Five girls,One guy and a Hot Tub  (Group Sex Story, Male- Female Sex Story, Fetish Porn Story.)

Justin gets to stay at a house in the hills with only his sister and her friends for company This is the story of my sister's 18th birthday. I was a 20 year old university student at the time and as a gift from our parents she was given the use of our holiday home at Mt Buller for a week. Every snow season the four of us; my parents, my sister and I, go up and stay for a week or two in early July depending on our commitments back home. Usually my sister and I both have a friend come up with us, but this year was different because my best mate Adam was in Europe for three months. My sister, Paige, was bringing four of her best friends along this year to celebrate her birthday while my parents would be staying with friends who also have a house nearby. And that is how I discovered I was going to be staying with my sister and four of her rather hot friends in a house in the snow for 6 nights. My parents gave me the option of staying with them of course, but I found it rather exciting to be staying with four hot girls nearby at all times so I declined under the guise of not wanting to put my parent’s friends out too much. - Sunday July 5th, 2009 - We left for Buller around 9am Sunday morning. With eight of us this year we had to take two cars. My parents drove with my sister, Paige, and her friend Kara. I drove my car with Paige's three friends Amanda, Dawn and Melissa. Melissa was slightly older that the other girls. She was 19 already and I got on well with her. She was extremely outgoing and had a reputation for trying anything once. 5'6" with Auburn hair, a fiery personality to match and great tits. Her pert breasts always seemed to stand out and were probably a C cup. Amanda and Dawn were identical twins. They were insanely cute. 5'2" tall, each with Brown hair and that slight baby face quality that makes them look years younger than they really are. They're 18, a few months older than Paige and their breasts were a perfect perky B cup. Dawn had a crush on me, although I didn't know as much at the time. Kara, hmm Kara. She is the stereotypical blonde bombshell. 5'8" tall, long blonde hair and massive suffocate-yourself-in-those-D-cup tits. Then there is my sister herself. I get on great with Paige, I'd even say she is one of my close friends. Most of my friends seemed to fight with their sisters, but I can't recall ever having a negative interaction with Paige. She is 5'6" with brown hair that she streaks with blonde tips. She has a strong jawline, but not in that masculine way. It’s actually quite beautiful. The trip up to the mountain took a couple of hours, so there was plenty of time to chat. Dawn was very talkative and informed me that she had never been to the snow before and wouldn't be able to ski. She talked me into giving her skiing lessons. The trip was pretty uneventful. We arrived at around 11:30am and after Mum and Dad left we spent some time getting unpacked and showing the girls around the house. It was a large double story house with 4 bedrooms, 2 bathrooms and most importantly a hot tub/spa on the balcony at the back of the house. Half the balcony, including the spa itself was enclosed behind a glass wall to keep the heat in, but there was an uninterrupted view of the valley below and other mountains in the distance. The view alone was worth the trip. Now of course such a large house was quite a waste on just our family of four. Mum and Dad bought it as an investment to rent out during most of the year. Even in the off season there are always hikers and the like looking for places to stay. Everyone explored the house and chose their rooms. I unpacked in my usual room, while the girls had to share. Melissa and Kara got their own rooms while Amanda and Dawn were happy to share with Paige in the master bedroom. Everybody had lunch once we were settled and we hit the slopes at around 1:30pm. Dawn intercepted me as I was leaving the house and made me take her to rent her ski gear. Then I started teaching her the basics. I've been skiing most of my life and find it second nature. I've never taught before and found that its quite hard to put the motions I find natural into words. Eventually I escaped from Dawn and went down a few runs on my own before returning home as the sun started to set. Sunday night was when this story really starts to pick up steam. I cooked some meat on the barbecue for dinner and the girls started drinking. They had all brought a weeks supply of alcohol with them and weren't wasting any time. After dinner the girls settled in the lounge and started the fire. I grabbed a book I brought and went out onto the balcony to read, it was freezing outside of course but it wasn't too bad in the spa area. The girls were inside quickly getting drunk and making a lot of noise. They were quite distracting and I couldn't concentrate on the book. An hour or so later Dawn came out onto the balcony. She was wearing a small blue bikini that left nothing to the imagination. "Hey Justin. We're moving to the spa, Want to join?" she asked. "I was just going to read. You guys wouldn't want me ruining your party atmosphere, I'll get out of your way." "Sure we do! Come on, you have to join us." I was genuinely surprised she wanted me to join them, but I wasn't going to decline an invitation to jump in a spa with 5 hot bikini clad women, even if one of them was my sister. In hindsight, it may have only been Dawn that wanted me to stay. I went back inside and a few minutes later I was wearing my swimming shorts and lowering myself into the already warm spa. It was a decent size hexagonal spa that easily fits 6 people, although their knees tend to touch. Everyone else was already there and the only empty spot was between the twins so I eased myself in between them. Amanda was wearing a pink bikini that was otherwise identical to Dawns. Good thing they were colour coded, or I wouldn't have known one from the other. Kara, Melissa and Paige sat opposite us and behind them was the sweeping vista of the valley below, still lit by moonlight. "Ok," announced Melissa, "Justin's here so we can resume out little game of truth or dare." "What? You guys have been playing truth or dare?" I asked, surprise. Why would they ask me to join a game like that? "Oh yeah. We've been having lots of fun. Kara was even dared to show us her boobs." Amanda announced. What? I couldn't believe she would do that, and then be willing to continue playing with a guy. Then again I could tell Melissa and Kara were already pretty drunk so perhaps this wasn't so strange. Dawn reached out of the spa and picked up a wooden arrow that I hadn't noticed before. "I believe it was my turn," she said. Then Dawn threw the arrow lightly into the air and spun it. It spun around and landed in the water with a small splash, pointing toward Paige. "Truth or dare?" Dawn asked her. "Truth." "Hmm, Have you ever had sex, and with whom?" asked Dawn. Wow, this had well and truly escalated into the dirty stuff it seemed. I kept my mouth shut so as to not risk reminding Paige that her brother was here. My fear was baseless. "Gee Dawn, you don't want to ease back into it?" said Paige. "What? We eased into it earlier, and Justin is probably loving this." She was right, I was loving it. "Fine. Yes. I fucked Leon Hanks last year." Leon Hanks, I knew that name. He was that guy Paige went out with for a couple weeks the year before. She fucked him after just a couple dates? Paige grabbed the arrow and spun it into the air. It landed on Amanda. "Truth." said Amanda, before anybody could ask. "Have you ever experimented with a girl? if you catch my meaning." Paige asked her. Hearing my sister ask such a sexy question was quite a turn on. I hadn't heard her talk like that before. Amanda paused for a while and looked at Dawn, who nodded and said "What the hell, go for it." Amanda finally answered, and I noticed I was holding my breath, "Actually, yes. We both have," she signalled towards Dawn, "We're bi-sexual." Everyone erupted into chaos at the revelation, the sudden squealing and yelling from the other three girls hurt my ears, while simultaneously the thought of some girl on girl action made my shorts begin to stir. Dawn interrupted everyone almost yelling to put a stop to the other voices, "I prefer men though, just to make that clear." "But I prefer the pussy." added Amanda, with a twinkle in her eye. I was startled at her crassness and realized she was more drunk that I had first thought. I hoped she wouldn't regret coming out of the closet during a game of truth or dare. When everyone calmed down Amanda picked up the arrow next and spun, it landed on me. "Truth." I said. I was a little afraid of what these drunk chicks would have me do if I chose dare, yet at the same time I still wanted to. I decided to play it safe until someone else chose dare. "Ok Justin, how many women have you fucked?" Even though I saw it coming, the bluntness of the questions still hit me in the face like a bag of cement. I glanced at Paige, she looked intrigued. "Um, uh, I... Two... no, Three." I stammered. Maybe I needed to drink too, loosen myself up a bit. Perhaps tomorrow night. Everyone seemed content with that answer, I caught Dawn glancing towards my crotch. My dick was rock hard by now, but of course she couldn't see that through the turbulent water. I picked up the arrow and spun it myself. It landed on Kara. "Dare." she said. Expecting a truth, I hadn't thought of a dare. I stared at her blankly for a moment while I tried to think. "Ok Kara, why don't you show us all those massive tits of yours again." I said, then tried to swallow the lump that had formed in my throat. Everyone stared at me, mouths open. I stole a quick glance at Kara's chest. She was wearing a strange black and white bikini top, one cup white, the other black and it looked ready to rip apart under the strain of her massive cans. "Oh damn, I walked right into that didn't I?" she said. "Everyone else has seen, why should Justin be left out?" said Melissa. "Sounds good to me." said Amanda. Everyone looked at her with bewilderment. Kara slowly reached behind her back and pulled, her top dropped from her chest. Actually more accurately they popped off her chest, the potential energy held in her massive boobs released all at once. "Wow!", Only a moment after did I realize I had said that out loud and that my mouth was still open. Then I noticed everyone was staring at Kara's tits rather than me. Kara removed the top from the water and then settled back into her seat. Her nipples sat on the end of big dark bulging areolae, which sat comfortably just above the waterline while her massive melons floated in the water, teasing my cock. While I was staring at Kara's knockers, I didn't notice she had spun the arrow already. It landed on Melissa. "Dare." she said. "Go topless, like me." Kara immediately told her. Melissa didn't hesitate. She had her tits out before I could process what was happening. Her yellow bikini top floated in the water as I stared at her C cups. Her nipples were small and petite, softly sitting on tiny pink areolae. From then on things wound down. The two most adventurous and most drunk people were topless and the rest of us didn't seem to be willing to join. Everyone chose truth from then on. I had one more turn and Melissa asked me if I'd ever eaten pussy. I answered no. Everyone quickly became comfortable with the new clothing arrangements and we enjoyed the atmosphere and the view. My erection eventually went away and an hour or so later everyone started leaving the spa. I enjoyed watching Kara and Melissa's exposed tits bounce as they climbed out. Then I was the last to leave and went to bed. The slopes were a lot less busy now that the weekend was over. I got up fairly early and spent the morning skiing. After lunch Dawn found me and begged for more lessons which I happily provided. I forced her to take on a slightly steeper slope which resulted in her falling over, a lot. The girls went out for dinner that night, while I stayed in and actually got some proper reading done this time. The girls returned home at 10pm. Dawn went straight to bed as she was apparently quite sore and tired, but the others decided to go into the spa again. I was getting a drink in the kitchen when Melissa emerged from her room heading for the spa upstairs. She was wearing her very tiny yellow bikini bottom and nothing more. She wasn't even bothering to cover her tits on her way to the spa tonight. My cock jerked at the sight. "Joining us?" she asked. I just nodded and stared at her firm looking round ass as she walked away from me. Once she was upstairs I practically bolted to my room to get changed. When I reached the spa, Kara was already topless and Amanda was just removing her top as well. Her perky breasts stuck out and up, nipples hard as diamonds. And big too, huge even. Her very pink nipples were like those erasers on the end of pencils, thick pencils. Their areolae were small and flush against the curves of her mounds. Dawn was missing and Paige was the only one without her tits hanging out, which I was relieved to see. My heart lurched when I realized I hadn't even considered that my sister was here in my rush to get to the spa so I could perv on some jugs. I sat between Kara and Amanda and grabbed a drink, this would be a good night. Relaxing in a spa with my sister and 3 of her half nude friends. We talked briefly about the nudity and how comfortable the girls felt with it, then Melissa propositioned me. "You know Justin, it's not exactly fair that we're baring a part of ourselves and you're not. You should take those shorts off." "I don't think so. My sister is here remember." I replied. "That's no fun," said Kara, "I dare you to take them off. Paige won't mind I'm sure." Paige didn't say anything, but she looked pretty amused. Did she know they were planning this? "What would I get in return? I've got more to worry about with Paige here, is that worth more to you?" I asked. "How about... If you let your dick out, I'll give you a handjob." Kara offered. My heart lurched, and my dick jerked in reflex. Apparently this was news to the other girls as well who all exclaimed in shock at Kara's forwardness. Paige protested, "Hey, you never said anything about jerking my brother! I agreed you could see it if he agreed, thats all." Before anyone responded, I interjected on instinct "A deals a deal.". I quickly stood up and pulled my shorts down in one swift motion before I lost my nerve. I hadn't drunk much at this stage, but I like to think I had enough of a buzz to justify my rash actions. My dick sprang into the air and I looked at Paige as I did this, her eyes were wide and her mouth was open. Then I sat back down, partially hiding my cock in the bubbly water, its head quite visible as it almost broke the surface. "Holy shit. That looks massive." said Melissa, "how big is that? It's much larger than Andrew's." Andrew was Melissa's boyfriend, she was the only one of the group to have a boyfriend. "7 inches." I said. I had never thought of my dick as particularly large, but I was happy to hear Melissa say otherwise. It made me feel superior to Andrew somehow. Andrew was in my year level at school. I never liked that guy, he thought too highly of himself, and it showed. He was a bully basically. Suddenly I wished it was Melissa who'd offered to give me a handjob, just to stick it to Andrew. "Great, that's something I needed to know." said Paige. She sounded exasperated. I slouched back and relaxed as Kara inched closer and reached for my cock. She started lightly caressing it and then slowly jerking it as she wrapped her hand more firmly around my tool. I stretched my legs out and put my feet up on the seat opposite, the space freed by Dawn's absence. This allowed me to rest my shoulders on the edge of the spa and float to the surface, my cock protruding completely from the water near the center of the spa. Karas hand moved up and down my shaft faster and faster. I closed my eyes and zoned out as the girls talked amongst themselves. I focused on the sensation in my dick as the buxom blonde to my left performed her promised handjob. Moments later her hand disappeared, then reappeared from a different direction. My eyes opened in a flash and I found Melissa now had her fingers wrapped around my tool. Suck on that Andrew I thought, your girlfriend is pleasuring my superior dick. My eyes darted to Paige and then quickly back to Kara's massive tits. My sister seemed to have forgotten she was sitting in a spa with 3 other people and was staring intently at my dick while her hand seemed to be between her legs. This almost tipped me over the edge, but luckily Melissa released my dick right at that moment. Kara's hand returned soon after and resumed her handjob. I stared at her tits which bounced lightly on the surface of the water as her arm jerked up and down, milking me. Then I started darting my eyes around trying to look at Paige without her knowing. I glanced at Amanda's tits, then Melissa's, then to my sister's water concealed crotch and back to Amanda's chest. Paige's arm was definitely moving slightly, she was covertly masturbating to her brother getting jerked off by her friend! Never in my wildest dreams had I imagined such a thing. It was a massive turn on however and after a couple more discrete glances I couldn't hold on anymore. My cock erupted and I spewed cum everywhere. Thick gobs of it landed in the water, on my stomach and dribbled down Kara's hand. The girls all screamed in delight and reflexively jerked backwards, having not realised they'd all slowly leant forward to watch. "That was interesting." said Amanda. "That was hot!" amended Melissa. I relaxed back into my seat, the cum washed off my body by the water. We all sat there in silence for the next 10 minutes or so watching my cum float around the spa, being pushed around by the air jets erupting from the surface. I noticed a clump float into Paige's side. I tried not to look, but the thought of my semen contacting my sister's skin was a massive turn on. I was quickly hard again. I secretly wanted another handjob. I secretly wanted my sister to administer it. But the girls had other ideas and started climbing out, apparently that was enough for the night. Kara grabbed her towel and wiped the cum on her hand into it. I hadn't realised that she had left her hand covered in cum, my dick jerked harder. I climbed out of the spa and put my shorts back on. "Hehe. He's hard again already." said Amanda, pointing at my dick as I pulled my shorts up. "What can I say? I'm surrounded by topless women, I'm only human." I replied. Everyone went inside and I spent some time cleaning my cum out of the water. Then I made my way to bed. I was still too worked up, so I masturbated in bed thinking about my sister's hot body. I really wanted to see her topless and wondered if I'd get the chance, this week was quickly becoming the most interesting week of my life. I blew my load again while picturing my cum brushing Paige's skin in the spa, which led to fantasizing about cumming onto her chest. I chastised myself for thinking of my sister in that way, but I couldn't help it. I had a difficult time sleeping after fantasizing about my sister for the first time ever. So I got up, had a shower and headed out to ski as soon as possible. I found Dawn that afternoon on one of the beginner slopes. She was doing very well, so I suggested she should try one of the intermediate runs. Barely anyone went on it, so she wouldn't be as embarrassed if she stacked. She liked that idea. I followed her slowly down the run and part way down she stopped for a rest. We started chatting and she brought up the night before. "You know, I'm kicking myself for not joining you guys in the spa last night." "No sweat, there is still a good 5 nights left. You're still learning, so you need recovery time." "True," she replied. Then she hesitated for a moment. "Amanda told me about your adventure last night." "Oh." "It sounded hot. Did you really blow your load in the water?" She was getting very close as she spoke, until her face was practically against my chest. "Ah-huh." was all I could bring myself to say. She backed off for a moment then, "It makes me wonder how far these escapades will go." "Yeah, me too." The conversation was taking on a more casual tone and I found myself becoming quite comfortable talking about sex with the hot twin. "How far do you want them to go?" her tone was very casual now, no hint of the previous sexual tension. "As far as Paige allows them too I suppose." "So not very far then." "I wouldn't be so sure." I replied. "Can you keep a secret?" "Ok, what is it?" she asked, getting all interested. "Well it's probably not a secret really, the others might have noticed... But Paige didn't seem as negative towards the activities of last night as she would say." "What makes you think that?" "While Kara was jacking me, she had her hand between her legs." Dawn was shocked, "No way!" "You have to promise not to tell anyone. She was very discrete, the others may not have noticed." "Ok, ok. I promise. You really think she was diddling herself while her brother was being jerked?" she asked. I just nodded. "That is... hot, “she continued, "You know what? I don't want to wait for tonight and risk Paige putting an end to all this." As she spoke, Dawn dropped to her knees and placed her hand on my fly. "Do you mind?" I nearly choked as I stuttered "Ah, no. Not at all. Mind what?" The cute twin zipped down the fly of my snow pants to find my track pants underneath, then she pulled them and my boxers down at the front in one motion. My shaft became visible and she hooked her thumb under it and pulled. My dick flicked out into the freezing air and began to inflate as the hot minx with her face inches from it gasped. "Very nice," she said, "It must be cold." Then without hesitation she pull her goggles up so they rested above her eyes then reached forwards and sucked the head of my cock into her mouth. "Oh, fuck yeah!" I exclaimed as she started sucking the length of my cock, swirling her tongue around it. Then I remembered where we were. I scanned the scenery but nobody was around. We were standing right in the middle of the track on a flat section. If anybody came down this run there would be no hiding what was going on. I lowered my gloved hands onto the back of Dawns head as she rocked back and forwards over my rock hard knob. I slowly thrust forward with my pelvis, holding her head in place. I found the depth where she started to choke and withdrew, then started to fuck her face. She was still wearing her skiing goggles which pressed into me with each thrust. Suddenly someone rounded the corner further up the track. I was facing that direction so Dawn wouldn't have seen him. There was nothing I could do, so I just kept fucking her sweet face. The skier got closer and closer then passed us quite quickly, his head turned towards us and his jaw agape, then he was gone around the next corner. Dawn jerked off me when she noticed him pass. "Oh shit. Why didn't you warn me?" she asked. "There was no time to do anything, so I didn't say anything. It was nobody we knew thankfully." "Almost gave me a damn heart attack." she said while clutching her chest. Then she quickly resumed her sucking. I replaced my hands on her head and started fucking her face with increasing ferocity. The pleasure built higher and higher as my cock slid in and out of her wet lips until finally I reached a climax and my cock exploded. Dawn choked as I shot cum down her throat. She pulled back and my dick popped free, still erupting hot cum. She coughed up the cum I'd shot down her throat which dribbled down her chin as blast after blast of semen continued to spew forth from my junk and slam into her face. When my orgasm finally passed, her cute face and goggles were covered in semen. "Shit, sorry. I should have warned you." "No it's fine." she said with one of her eyes sealed shut by my white goo, "I was planning to swallow, so I actually should have been ready for it. My bad." Dawn cleaned up as best she could, wiping the cum off her face and flicking it onto the snow while she continued to try and clear her windpipe of any remaining cum. Once it was no longer noticeable we headed down the mountain again. That night we all went back to the spa after dinner. I didn't wait for an invitation this time and nobody objected. Everyone except Paige was already topless when I arrived. Dawn was the first to speak after I arrived, she had a vodka drink in her hand. "Hey Paige. Why don't you take your top off. Everyone else has. Even Justin got his dick out last night I hear." "No way. I'm not stripping in front of my brother." replied Paige. I noticed her eyes dart towards my crotch as she said it. "Oh don't be a spoilsport!" cried Amanda, "I want to see those tits too." The other girls joined in with the chastising. Would she buckle to peer pressure? "What if Justin removes his shorts again?" asked Dawn. It didn't take much coaxing and soon Paige was reaching for the drawstring on her bikini top. The girls weren't even drunk yet this time, I was amazed how quickly this was moving. Paige released her top and threw it clear of the spa. Wow is the best word to describe what I felt and saw next. With the exception of this week I'd never thought of my sister sexually before and wasn't really aware of what kind of breasts she had. She easily had the second largest tits here after Kara. They were a generous C cup and my jaw dropped when I saw them for the first time. Her hard nipples were darker than the twins' and not as large as their eraser behemoths, yet they were bigger than Melissa's. All the girls were now topless. "Nice tits sis." I can't believe I said that. I felt myself blush. Without realizing it I had become very comfortable with the sexual nature of this whole trip. I stood and once again dropped my shorts and threw them out of the spa before sitting down again. "Nice cock bro." said Paige, then she blushed also. Melissa exclaimed, "Oh yeah. This is hot! Brother and sister checking each other out." Without any prompting Melissa reached for my dick and started jerking it. I thrust my pelvis forward so my cock poked out of the water. I reached over in turn and placed my hand on her left tit, giving it a bit of a squeeze. "Can I try?" asked Dawn. Melissa released my dick and Dawn moved towards it. Then she lowered her face into my crotch and sucked my shaft into her mouth. Everyone jumped up in shock and started shouting at once. "Holy shit!", "no way!" and "you go girl!" were some of the things I heard cried out. Everyone quickly settled again and I pulled back out of Dawn's mouth so I could reposition myself. I sat up on the edge of the spa and looked out over the valley below while Dawn started to suck my cock once again, and for the second time that day, although I assume nobody else knew about that. It was a different experience receiving a blow job in front of four other girls. It becomes so much more intense. I found all I could do was watch the others and how they were watching me. Paige looked fascinated but was trying to hide it, Melissa and Kara moved in close to get really close up views of my cock disappearing into Dawn's face. "What's it like?" asked Paige. Everyone looked at her. "I mean, not his... but sucking cock in general. I've never done it." "Dawn has a cock sucking fetish." Amanda told her. I could attest to that. Dawn stopped just long enough to say, "You want to try?" Paige just glared at her, giving her best death stare. I placed my hands on Dawns head once more as she continued to bob up and down on my cock. Then I looked at Paige's tits. I'm not sure why I did it so blatantly, it wasn't initially conscious, but I couldn't help myself and didn't care about hiding it any more. So while I was getting my dick sucked by a twin goddess, I stared intently at my sister's rack. "Ah Paige, he's staring at your boobs." Amanda informed her. "They are hypnotic." I said. "And I'm staring at his cock getting sucked, so I guess we're even." said Paige. This continued for a good 5 minutes. It's hard to actually tell when your dick is in some chicks mouth, but it felt like 5 minutes. So for 5 minutes I stared at my sister's cans while Dawn's tongue swirled around my dick and her head bobbed up and down in my lap. Then I came, and I came hard. My balls tightened and I erupted into the back of Dawn's mouth. This time she was ready and caught all of it, slowly withdrawing her head until only the head of my cock remained between her lips and I released shot after shot of hot spunk. "Is he cumming?" Kara asked right as I finished and Dawn was carefully lifting her face away from my member, careful not to allow any semen to escape her lips. She then turned to face Kara and opened her mouth, displaying the massive load of cum inside. Then in one smooth motion, she closed her mouth and swallowed every drop. "Holy shit." exclaimed my sister. Dawn went back to my knob and licked it clean, swallowing what she collected. Then I slid back into the spa and relaxed. The rest of the night was pretty uneventful, sex wise anyway. We all just sat around partially naked, or fully in my case and drank, talked and made fools of ourselves. I groped each of their tits except for Paige's at various times, and they all jerked my dick briefly as well, again except for Paige. Eventually we all got out after we were all pruned, went inside and lay naked or partially naked by the fire to dry off. Then we slowly drifted off to bed one by one.On Wednesday Dawn found me as I was leaving the house. We spent most of the day together on the beginner and intermediate slopes. I really came to enjoy her company and it was becoming very clear she had feelings for me beyond just wanting to suck my dick. Nothing sexual happened all day, but we talked about how excited we both were to get back in the spa. Eventually night did come. We ate at a local pub which was absolutely packed, then headed home at around 9pm. I went to my room to change and headed to the spa. Dawn was already there, and had a surprise for me. At least, I assumed it was Dawn but didn't know for sure since she was completely naked and indistinguishable from her sister without her colour coded bikini bottoms. She greeted me with a hug, then did a little spin to show herself off. Her pussy was completely bald, ass nice and round, hips wide. She had a classic hourglass figure with perfect tits and pussy to match. My cock grew to its full length in seconds. "Wow!" I said, "You're incredibly game tonight." "I told you I was excited about tonight. I want to suck you off again." she gave me a wink and spun around again to show me her ass, giving it a little slap as she did so. Then she stepped down into the spa and I joined her. The others came out together, all topless and took their seats in the spa. Amanda sat next to me, placing me once again between 2 smoking hot twins, one of them completely nude. It wasn't long before someone noticed Dawn's condition. The bubbling water obstructs a clear view pretty easily, but the unbroken expanse of pale skin was pretty noticeable. Paige noticed first, "Dawn! Are you nude?". My sister's tits bounced lightly as she said it. "Oh yeah. I couldn't be bothered putting something back on after getting undressed." The little exhibitionist then stood up and showed off her ass and pussy to her friends. Amanda squeeled "Woo, go sis. Show off that ass. It's a good one if I do say so myself." Then Amanda stood up and wiggled her hips out of her own bikini bottoms. They dropped to the water revealing her own completely bald pussy. 

Then she sat on the edge of the spa and lifted her legs out of the water so she could completely remove the rest of her clothing. Once she was done she stood back up and showed us her firm ass, it was identical to Dawns of course. I realized that now they were both nude and side by side, there was absolutely no way to tell them apart. At least not for my untrained eye. Paige had a hand in front of her agape mouth as her friend completely stripped in front of her. "One of you needs to grow their pubes out or something so we can tell who's who." I said. They laughed. As soon as Dawn was done stripping, Melissa stood up and shouted "Yeah, Part-ey!", then faster than you could say nudity, the rest of her bathing suit was lying on the balcony as well. Her pussy was the opposite of the twins, darker and covered in wild hair, only trimmed on the sides to prevent anything showing out the sides of her bikini. Kara immediately stood and joined Melissa in getting her kit off. Kara's twat was lovely as well, neatly trimmed into a strip of blonde hair above her slit. "What about you Paige?" Dawn asked, "feel like a little exposure?" "Perhaps not, but don't let me bring the party down." she said. Damn, my heart sank slightly. I could see my sister's breasts but I found I now wanted to see what was between her legs as well. Was she shaved? Or wild and bushy? While I was staring at the bubbly area between my sister's legs, Dawn grabbed my cock in her hand. "Ok, get back up on the edge so I can suck this beautiful dick again." she commanded me. "Bloody hell," Melissa said as I lifted myself out of the water and onto the edge like the night before, "You're becoming a bit of a slut aren't you Dawn? Let me suck him off." Wait, what? The only girl with a boyfriend was going to be the second one to suck on my cock? Suck on that Andrew! Dawn backed off and Melissa moved in. She draped her hand around my shaft and then started licking the head of my dick. I groaned in ecstacy. Kara, Amanda and Dawn all moved in to get a closer look. Then Amanda grasped my shaft when Melissa removed hers and started jerking it up and down while Melissa continued to lick and suck on the tip. The four of them started sharing my cock from that point on. Melissa deepthroated me before releasing my dick into the air and allowing Kara to sink her mouth over it. Melissa, Kara, Amanda, Dawn, back to Melissa. All four of them sucked on my meat like it was the most amazingly sweet candy in the world. I couldn't stand the waves of pleasure sweeping through my body much longer. I told them to stop for a moment or I would explode. "Hey Amanda, you're bi... so does that mean you like licking pussy?" Kara asked. "Yes..." she replied, waiting for Kara to elaborate. "I've never been eaten out before." "Say no more." Amanda quiped. Kara climbed out of the spa and lay on her back, spreading her legs so her pussy was exposed to us all. Amanda moved in and her head blocked my view as she started eating out her friends pussy. "Holy shit!" said Paige as she looked around in bewilderment, as if she didn't believe this was all happening. But that was when I noticed she was masturbating furiously, so I guess she didn't really mind. She wasn't trying to hide it tonight, her hand was clearly down the front of her bikini bottoms pleasuring herself and I tried to imagine her fingers penetrating her love hole. Right as I was doing so two things happened at once. Melissa's face buried itself on my cock once more, and my sister looked me right in the eye. She didn't look ashamed to be masturbating in front of me, in fact she got into it more once our eyes met. Her back ached back and she squealed out loud without ever breaking eye contact. "Fuck yeah," she cried, "suck my brother's cock you slut." Finally I broke eye contact to watch Kara getting eaten out by Amanda for a while. A hand removed itself from my balls and Dawn climbed out of the spa. I was so engrossed in my sister's masturbation that I hadn't even noticed Dawn was playing with my balls while Melissa sucked me off. Melissa continued to bob her head up and down on my cock while Dawn walked around the spa. She stopped above Kara's head, planted her feet on either side of her with her ass to me and slowly squat herself down, lowering her pussy onto her friends face. Kara didn't resist or speak up in any way, instead she started licking at Dawn's cunt. I couldn't stand it any longer, this was quickly turning into a oral gangbang. The subtle musty scent of the pussies being eaten a few feet away wafted across my nostrils. "I'm gunna cum." I cried. Melissa removed her face from my dick and started stroking my shaft with her hand as fast as she could, "I want you to cum on my face." "Oh yeah," Paige interjected, "cum all over her face bro." And so I did. My cock spasmed and started to shoot a torrent of semen across Melissa's face. The first shot hit her in the eye, sealing her eyelid shut. The second shot missed her completely, flew over her head and landed in the water, right in front of my sister. All the follow up spurts landed across Melissa's nose and mouth, coating them in a thick white glaze. When I was finally finished spewing my load over Melissa, she started scooping it off her face and dumping it in her mouth. When her mouth was full she swallowed the whole load. "Oh, swallow my brother's cum." demanded Paige, "yeah. Oh fuck. I'm cumming!". My sister started bucking against her hand as her climax hit. I could see the cum that escaped Melissa's face lapping against Paige's arm and stomach as she shook uncontrollably from her orgasm. As my sister started to come down from her orgasm, the other 2 reached theirs. Dawn's hit first, almost immediately followed by Kara. Dawn nearly fell backwards as her pelvis spasmed under the intense pleasure Kara was obviously giving her. Amanda had trouble trying to hold Kara's ass in place as she continued to lap at her pussy. Finally everyone was done cumming. We all collapsed into the spa and rested. Everyone just sat there for another half hour or so, before leaving the spa. I gave Dawn's ass a light slap on her way out. Or was it Amanda? - Thursday I slept in, I was beat from the night before. I woke at 10am and all I could think about was the incredible time we were having in the spa every night. I stayed inside until after lunch before finally going out onto the slopes. Everyone else had been out since before I woke up. It didn't take Dawn long to find me once I got out there, Amanda was with her. "There you are sleepyhead." she said, "I've been looking for you." "Yeah? Have some nefarious intentions up your sleeve do you?" I asked. "Not really. Just want to suck your cock again." A woman near us heard and gave us a harsh look of judgment and disgust before turning around and walking off. Amanda chuckled, "You'd think she'd never heard someone offering to blow someone in a public place before." "You really do have a blow job fetish don't you?" I asked Dawn. "Yep." she said, beaming. "How about we go down one of those empty runs again?" So we set off towards the least used intermediate run. Amanda came with us, saying she wanted me to pump some man juice into her belly after her twin sucked it out of me. Her words, not mine. It made me wonder what these girls got up to back home, or was it just the mountain air turning them into total sluts. We stopped part way down the run. Dawn was getting quite good and didn't fall once. Amanda spotted a little alcove between the trees on the left and we all followed her in there. It was out of view to anybody further up the slope, and hopefully anybody that went flying past wouldn't think to look sideways once they were in line of sight. As soon as we stopped Dawn had my cock out and down her throat in mere moments. She very quickly brought me to orgasm, the combination of the cold mountain air, being in public and being watched by a girl that looked identical to the one sucking my dick made the blow job I was receiving unbearably pleasurable. "I'm about to cum." I cried, half choking on my words as I struggled to get my breath. Dawn pulled away from my cock, releasing it back into the cool air. Amanda quickly moved in front and opened her mouth. I took hold of my dick and stroked it as fast as I could, placing the head on Amanda's tongue. A second later I exploded, spewing a torrent of white goo into Amanda's mouth. She collected it all and when I finally stopped cumming and removed my cock she proudly showed off her mouth full of semen. Dawn moved up to Amanda and the twins kissed. My cock jerked reflexively as I heard slurping sounds. They separated again and both opened their mouths, each showing pools of my cum on their tongues. I couldn't believe how slutty these girls were. After the twins swallowed all my cum and licked my cock clean, we continued down the slope again. We spent the rest of the afternoon skiing together and the girls gave me another blow job each across the afternoon. Dawn and myself really hit it off and found we had a lot in common, beyond the obvious love of blow jobs. I got on great with Amanda also, but not in the same way. I felt a special connection with Dawn, a connection that had been growing since we arrived 5 days ago. That night we had another barbecue and ate on the balcony. We started drinking and chatting, surprisingly everyone kept it very non sexual. Until an hour or so later Melissa yelled out "Spa time!" and stripped all her clothes off. Everyone else quickly followed and climbed into the spa. Paige was the only one still wearing anything and kept her pants on. She went to go inside when the girls stopped her. "Where are you going?" asked Melissa. "To put on my bikini." she replied. "Oh, come on. Your brother's had his cock out since the second night. Just take your clothes off and get in here." said Amanda, "Besides, I want to see that sweet pussy of yours." "Me too." added Dawn. Paige looked at me, then down at my hard dick, hidden by the turbulent water. "Fine." she said, with a grunt. A moment later her pants and panties were on the deck and I finally laid my eyes on my younger sister's succulent pussy lips. She was almost completely bald down there with a small triangle of neatly trimmed hair just growing through above her slit. I couldn't stop staring. While I was busy ogling my sister's crotch as she lowered herself into the spa, Kara started off the activities by sliding a hand under my ass and prompting me to lift myself up, exposing my hard knob to the air where she quickly sucked it into her mouth. Melissa soon joined in and the two of them shared my dick between them, sucking and licking my shaft while the other played with my balls. While they polished my cock, Amanda made a move on Paige. I didn't pay enough attention to what happened, but soon I noticed Paige climbing out of the spa. She lay back on the deck and Amanda lowered her face between my sister's legs and started lapping at her pussy. "Oh fuck yeah," I cried, "eat my sister's twat." The thought was too much for me, as I watched my sister receiving head from her friend I had my first orgasm of the night and began shooting cum down Melissa's throat as she was trying to deep throat me. She wasn't expecting it and choked, pulling herself off me and coughing up gobs of saliva and semen into the water. Meanwhile I continued shooting cum into the air. Kara moved in and took a load of cum on her face before she could get my dick in her mouth where I deposited the last of my spunk. "Oh my god! This feels so fucking good!" Paige cried out as Amanda flicked her tongue over my sister's clit and pumped her fingers in and out of her pussy. I relaxed back into the spa and watched the show. Amanda was clearly pretty pro at eating pussy and drove my sister wild. Soon enough Paige started to buck against Amanda's head and climaxed. It was then I noticed my dick was once more rock hard, the intense sexual energy of the scene in front of me and the strong smell of sex revived my cock in record speed. Dawn noticed it at the same time. She moved over to me and swung her leg over me. "No way." said Melissa, having recovered from my assault on her throat. I pushed myself out of the water and onto the edge of the spa. Dawn followed me and put one knee on the deck while the other leg supported her on the seat in the spa. Then she lowered her bald cunt onto my rock hard cock. "Oh my god." mumbled Paige, having come down from her orgasm and only just starting to pay attention to what was happening. Everyone else was just staring intently as I slowly penetrated Dawn's hot snatch. Once Dawn was sitting in my lap with my cock buried inside her, she lifted her other leg up and planted her knee on the deck as well, hooking her arms around my back for support. Then we started to fuck. I slowly pushed up into her body as she rocked her pelvis back and forth. The sensations were intense. I placed my hands on her perfectly round ass cheeks and spread them as I drove my cock between her pussy lips and up into her. This gave the other four girls a perfect view of my hard rod penetrating their friend, and Amanda's sister. After a few minutes of fucking slowly, I dropped backwards and lay down on the deck, my legs dangling in the water. Dawn leaned forward and planted her hands on the deck also, then began bouncing ravenously on my cock. "I didn't know Dawn was such a slut." said Kara. "Me either, I had no idea she had this planned." said Amanda. "It looks so filling." said Paige. My sister had moved right up between my legs as she watched me fuck her friend. Then she reached out and grabbed the base of my cock with her right hand for the first time as Dawn continued to bounce up and down my shaft, ramming her pussy lips against Paige's fingers with each motion. After a minute of this, of which I don't know how I didn't cum almost immediately when Paige touched me, I was finally ready to blow my load again. "I'm gunna cum." I warned. Then I immediately released into Dawn's cunt. I've never come twice in such a short time frame before, yet despite that I released what can only be described as a flood of molten white lava up into the beautiful woman riding me. I continued pumping cum into Dawn's repository for a spectacularly long time. Her pussy began to over flow and I could feel my sperm dribbling down all over my sister's hand and onto my balls. By the time I stopped cumming, my ejaculation had been accompanied with sharp jerks of my entire body and I was exhausted. Dawn leaned forward and kissed me as the spunk in her cunt continued to leak out around my cock shaft. I kissed her back passionately, our tongues intertwined. Then I felt my cock get pulled free of Dawn's pussy. Dawn rolled off me and collapsed on the deck. I then had an unobstructed view just as my softening dick disappeared into my younger sister's mouth. I felt the eyes of four girls burning into my crotch as they watched for the first time as their friend licked the excess cum off her brother's dick. Out of the corner of my eye I could see Dawn scooping cum out of her pussy. For a good 5 to 10 minutes Paige slowly and lovingly licked my knob clean as the others looked on in silence. Perhaps miraculously I then began to become hard again, I had been so incredibly exhausted I didn't think I'd be able to get it up again even with my sister slobbering over my cock. However, I was soon rock hard once again and Paige began to bob up and down on my rod. I put my hands on the back of my sister's head and pushed her down until my cum covered balls squashed up against her chin. She took my entire length without any troubles at all. I began thrusting up into her throat, becoming more and more forceful until I was fucking my younger sister's face like she was some cheap whore. "I'm gunna cum!" I shouted, releasing my sister's head from my hands as I didn't want to choke her. Paige lifted off my dick slightly as I began to erupt into her mouth. She swallowed each wad of semen the instant it left my dick, letting none escape. My sister was a dirty cum drinking slut after all, just like the four girls watching us. When it was all over and Paige removed herself from her brother's crotch, everyone just collapsed on the deck. Nobody said a word for fear of ruining the atmosphere. Shortly after we all made our way to bed without speaking a word. I caught Paige's eye briefly as she left the scene of the crime, but I saw no regret, only lust. I knew this wouldn't be the end, my sister would taste my cock again I was sure. I woke early on Friday. Not because I couldn't sleep after being sucked off by my sister, but because there was a blonde head in my crotch at 7am. I slowly woke from my drowsy state and smelled breakfast cooking down the hall. Pancakes? Waffles? I couldn't tell. My cock slowly roused with me as the mouth surrounding it moved up and down, a tongue travelling along my shaft. I was quickly as hard as nails. "Morning." said Kara as she removed her face from my dick long enough to speak, "I couldn't stop thinking about you being blown by your sister. I was so horny I had to come in here and suck you myself." "I don't mind." I replied. I could wake up like this every morning. I opened my eyes fully for the first time as I adjusted to the light, my curtains were already open and the bright morning sun was streaming in trying to blind me. Kara must have opened them in an attempt to wake me. I looked down at her again, now able to see more than a blonde blur moving over my knob. She was buck naked, with her round luscious ass sticking up in the air behind her. Suddenly I was very aware of her massive rack resting on my legs as she slurped at my cock with increasing vigour. I closed my eyes again and fell back against the pillow to relax and enjoy my early morning blow job. Kara's tongue danced around my stiff rod as her lips moved up and down like a piston. Her saliva pooled around the base of my shaft and started to flow down the sides of my balls. A few minutes later I couldn't take it any more. The intense pleasure rose up my spine and down my legs to my toes as my orgasm crashed over me and my rock hard cock began to shoot its first load for the day into the busty chicks mouth. Kara moved off my cock as she swallowed the first shot of semen I'd deposited behind her lips. Simultaneously I shot my second stream of cum against her closed lips, then continued to shoot strands of thick semen all over her face. Most of it stuck there, but some fell back down onto my stomach. As soon as I stopped erupting my fluids onto her face, her tongue quickly darted out and gathered up all the excess cum that had failed to stick to its mark. Kara swiftly licked me clean and then stood up on the bed, giving me an unobstructed view of her naked form. Even from here I could see her pussy lips were dripping with moisture. "Thanks for breakfast." said Kara, before she stepped down from the bed and wandered off back toward the kitchen. Her face still plastered with cum. I soon got up and made my own way out to the kitchen. I had slept naked and didn't bother putting any clothes on. Luckily the heating had been left on all night. All 5 girls were already up and eating pancakes. All 5 were naked and Kara still had cum on her face as she bit down on her pancake. She noticed me looking at her and said, "What? I'm saving it for dessert." Paige laughed then gasped as orange juice went up her nose. "You slut." said Dawn in my sisters place, giggling to herself. "Hey, I'm not the one that fucked him last night, I just like how his jizz tastes." retorted Kara. "I didn't say there was anything wrong with that." replied Dawn, "I'm a bigger slut than you." We all ate breakfast and were soon out in the snow again. Paige and I caught up with our parents for lunch and hung around with them and their friends for a few hours. I called it an early day after that and went back to the house to read my book. That night after dinner, we all stripped naked and made our way out to the spa. Before I could even sit down, Melissa had her mouth on my cock and was sucking away. Paige sat down next to me and I couldn't look away from her free hanging tits as they lowered into the water. I reached over to her on my left with my right hand and grabbed her right breast in my hand as I settled into the water, resting my shoulders on the edge and holding my crotch up to water level so Melissa could continue sucking. Despite what had happened the night before, and how nonchalantly she was taking it, I still felt my throat close up slightly in anticipation of a recoil from Paige. My fear quickly subsided as my sister moaned softly instead of slapping me. I quickly lifted my left arm out of the water and put it around her neck, reaching down the other side to take hold of her other large breast. As I groped and kneaded my sister's melons, Melissa worked my cock with her mouth. She was quickly replaced by Amanda, then Dawn and finally Kara before the cycle restarted. They each took turns sucking me off for a while until Paige spoke. "Ok girls, back off for a bit. I'll show you how it's done." She didn't have to tell them twice. They all moved back into their seats as I released my sister's tits and she moved into position between my legs as I moved back and sat on the edge of the spa. Then for the second time in two days, my sister lowered her mouth over my member and sucked me into her warm mouth. Her tongue darted all over my cock shaft as she applied suction. My sister quickly settled into a slow rhythm on my cock. As she did so, Dawn lifted herself out of the spa and onto the edge, spreading her legs as she perched there. Amanda moved between her twin sister's legs and in the blink of an eye buried her face into Dawn's muff. "Holy shit, more incest." said Melissa, "I never even noticed the possibility." "We've done this before." said Dawn. I watched for a moment as Amanda lapped at her twin sister's pussy, then returned my attentions back to my own sister as she tried to suck me dry. I placed my hands in her dark, blonde streaked hair and pushed down on her head, ramming my cock down her throat and her nose into my pelvis. She barely flinched as she deepthroated me, pretty impressive. I didn't know she could deepthroat without gagging, I wonder if she'd done it before. "Look at Paige taking her brother's cock like a champ. She's the deep throat queen." I looked up at Melissa's voice. She was now on her back on the deck, with Kara between her legs. She had 2 fingers pistoning in and out of Melissa's twat as she licked at her clit. Paige continued deepthroating me. She released my dick, gasped for air and spluttered saliva and precum all over my balls before going right back down until that mixture was transferred from my balls to her chin and we repeating the process. Her eyes were watering like crazy, but it seemed like she liked it. I looked back at my sister's head in my hands as I throat fucked her and I started to felt that surge from my balls letting me know I was about to blow. "I'm gunna cum." I yelled. This time my sister pulled back a bit so I didn't erupt in her throat, then I blew. A torrent of hot semen spewed forth into my sister's mouth and she retained every drop of it. Blast after blast added to the pool growing in between her cheeks until I was finally spent. She slowly let my dick drop from between her lips as she moved back, trying to hold back the river of cum. My sister then angled her head up to minimize spillage and opened her mouth as far as she could, showing off the creamy white load I'd deposited there. Some of it flowed over the edge like the spillway of a dam and plopped into the water. Then she slowly swallowed the whole load, with her mouth still open. "That was the hottest thing I've ever seen." said Dawn. I slipped back into the tub and relaxed as I watched Dawn get eaten out by her sister while Kara lapped at Melissa's pussy. Paige lifted herself out of the water and joined Kara and Melissa by sitting on Melissa's face. Despite none of these three claiming to be bisexual, nobody was complaining about this situation. I watched the orgy of female cunt licking before me as my cock slowly recovered. Dawn, Melissa and Paige all had orgasms as their pussies were licked by their friends. Then the girls all swapped positions and created a daisy chain along the deck between the hot tub and the glass barrier overlooking the valley below where anybody hiking through the snow in the dark would get an eyeful. Although It'd be quite dangerous to do so, so it wasn't very likely. Each girl was on their knees and elbows with a pussy in their face and a face in their pussy, except for the end girls. Melissa was eating Paige, who was licking Amanda, who had her face in Dawn's twat while Dawn was fingering Kara's clit and thrusting her tongue down her hole. The girls moaned and groaned as they pleasured each other, prompting my dick to quickly regain its stature. Once it was throbbing with lust once more I climbed out of the tub and knelt in front of Kara, the only girl with her face not being coated in pussy juice. Kara quickly gobbled up my knob as I looked down the chain of sexy asses sticking high into the air. I began to thrust in and out of Kara's mouth when Melissa, at the far end of the chain, lifted her face away from my sister's snatch and peaked over her ass at me. She beckoned me with her finger then slapped her ass with one hand and spread her cheeks. That looked like an invitation to me. I pulled out from between Kara's lips and she collapsed onto the deck, resting her head sideways on the wooded planks while her ass stuck in the air in front of Dawn's face. I walked around behind the chain and kneeled behind Melissa. I grasped my cock firmly in my right hand and slowly guided it accurately between her legs. She was distracted eating out my sister and squealed when I penetrated her pussy lips. Paige looked back at the noise and gave me a big smile when she saw me behind Melissa with my cock buried inside her friend, then she resumed licking Amanda. Very slowly I drove my shaft deeper into that jerk Andrew's girlfriend. Melissa groaned loudly into my sister's muff as if she was trying to shout "Just fuck me already.", but I dragged it out and slowly inched my way inside her until finally my balls pressed up against her clit and her ass against my groin. Once I was balls deep in another of my sister's friends Amanda started squealing and pressing back against Paige's face as she approached climax. The force of her bucking passed along the chain until Melissa was slamming her pussy onto my shaft and I had to quickly grab onto her ass with both hands to prevent my dick popping out. I continued to hold on as Amanda fucked me by proxy, with my sister and Melissa in between. Amanda slowly ran out of steam and collapsed, pulling her face out of her twin sister's behind as she rolled to the side and slipped into the tub to get away from Paige's tongue. Apparently Paige didn't know when to stop and Amanda's nethers must have been too sensitive to go on. Paige pushed back once Amanda was gone, smothering Melissa's face and thoroughly coating it in pussy juices, then she pushed off and crawled on her hands and knees until she bridged the gap and planted her tongue between Dawn's cunt lips. Melissa followed her in small increments, sliding off my cock until only the tip remained between her lips, then waiting for me to move up and impale her once more so she could repeat the process until her mouth again formed a seal around my sister's clit. Now that we were all in position again I tightly gripped Melissa's ass cheeks and spread them as much as I could and started pumping my boner into her snatch as fast as my hips would take me. The sudden force I exerted made my balls let out a slapping sound with each thrust as they slammed into Melissa, but it also travelled right up the chain producing a shout of ecstasy from Kara as Dawn's tongue plunged deeper into her hot box. A few minutes later and I felt the dam about to burst. At the last second I decided to try something and pulled out as a torrent of steamy white cum exploded from my cock. The first burst hit her square in the ass hole, which was spread right in front of me, the tail end of it going up her ass to her lower back. I thrust forward so my balls pressed into the layer of sperm coating her anus and my dick aimed over her back right as the second wave released. My aim was true and a thick rope of my semen sailed right over her back and stretched itself from her shoulders, across her reddish hair and onto my sister's right ass cheek; hitting its target dead on. My sister ripped her face away from Dawn's twat as my molten seed struck her naked ass and she looked back at me with shock on her pussy juice smeared face. While she was turning around a third and fourth burst of hot cum splattered against the middle of Melissa's bare back. Followed by a few smaller shots dribbling down her ass crack as my dick came to rest nested between her ass cheeks. "Sorry, Bad aim." I lied once my orgasm had passed. Melissa started laughing as she pulled her face clear of my sister's cum splattered ass. "What's going on?" asked Kara as she and Dawn struggled to look back at the commotion. "Justin pulled out and blew his load all over Melissa's back, problem is that his distance is so good he hit Paige right on the ass also." Amanda explained with a grin plastered from ear to ear. Completely spent I moved back and collapsed onto my back. Melissa moved her face over Paige's ass and licked up the semen I had deposited there. Upon seeing that Amanda climbed back out of the spa and started licking up the cum coating her friends back and ass hole, then she moved over to clean the remainder off my shaft and balls. She left the cum in Melissa's hair for her to deal with later. Once I was all clean, Amanda took position behind Melissa and quickly licked her to the orgasm I had stopped just short of giving her. Paige, Dawn and Kara soon followed, reaching climax for the second time that night. Soon everyone was exhausted and lying on the deck regaining their strength. We all drifted off to bed and I found my knees hurt slightly from kneeling on the hard wooden deck for so long. I was exhausted and needed sleep, but I was also anxious that there would be no more late night spa sessions since we were heading home the next night. I woke early to a surprise on Saturday. Kara's back greeted me as I opened my eyes. The blonde hottie was riding my morning glory reverse cowgirl. After taking a moment to regain my faculties, I placed my hands on her hips and started meeting her bounces with upward thrusts as I greeted her. "You're a good alarm clock." I said. Kara looked back at me and smiled, "You seemed to enjoy it yesterday, and this morning you were already hard as a rock so I figured I'd take advantage." She gave me a wink and turned back to focus on her task of fucking my brains out. I was feeling exceedingly horning already, so I went all out slamming my cock into Kara's pussy. My view was stunning. I had a rear view of the blonde beauty with her massive tits barely visible to either side, they bounced along with her ass slapping my groin as my cock drove deep into her cunt. We fucked like this for a good 10 minutes with almost no respite. I think the events of this week were building up my tolerance. Eventually I couldn't take it any more. I lunged forward into a sitting position and grabbed Kara's big tits to hold myself up as my dick erupted. I pumped my hot seed deep into her womb. Simultaneously Kara appeared to reach climax as well. She screamed and arched her back, her head resting beside mine as her pelvis jerked over my erupting cock and her legs squeezed mine. We both came down from our orgasms and I collapsed backward. Kara fell forward on her hands and slowly gyrated her pelvis against me before lifting off my cock. I jerked involuntarily as the cool air greeted my dick popping free of her body. Next thing I know I was waking up again and it was 10am. I must have been so exhausted that I fell back to sleep right after. I dragged myself out of bed and headed to the kitchen to make some breakfast. While I was eating Paige emerged from her room and joined me, she was buck naked and I noticed that I was also. I was so comfortable with nudity now that I hadn't even thought to get dressed. Everyone else seemed to out and about already. "Nice hard on." said Paige as she started pouring some cereal. I looked down and saw she was right, I had a raging boner yet again and hadn't noticed it as it had become so common. "Thanks." I said, "Hey, sorry for cumming on your ass last night, hope you're not mad." "Not at all. You did it down my throat remember? Getting some on my ass is nothing compared to that. I was just shocked as I wasn't expecting it." "Ok cool. In that case would you be shocked to hear I was deliberately attempting to hit you?" She laughed, "A little. You know, I'm glad this week became what it is. To be honest, I've been lusting after you since I hit puberty. " As we ate breakfast Paige told me all about the feelings she had had for me over the years. How she'd tried to spy on me a few times. Even how one time when she saw me coming out of the shower six months ago wasn't an accident. I decided to refrain from telling her that I'd never really thought of her sexually until this trip, I didn't want to hurt her feelings. I did however comment on how hot she was and how the feelings were mutual. "Actually, I think that's why I was so reluctant when things turned dirty." She continued, "I was too reluctant to act on feelings I've been suppressing for all this time." We continued our candid chat as we ate and I discovered how turned on Paige got watching me fuck other women. I told her it was mutual. "You sure have a purdy mouth. Feel like some additional breakfast?" I asked once we had both finished eating. "Perhaps. I'll show you just how pretty my mouth really is." She walked over to the couch and beckoned for me to sit down. I did as directed and quickly my raging member was embedded between my sister's sweet lips and she gave me one of the best blow jobs I'd ever experienced. Only eclipsed by the ones she'd given me previously. She licked and twirled and deep throated my cock like a pro. "I'm gunna cum." I announced as my ejaculation approached. Paige pulled her face off her my dick and stroked it rapidly, aiming it right at her nose. "I want it splattered all over my face." she told me. I obliged. My semen spewed into her face with such force it coated most of her face in one blast while subsequent blasts slammed into her already glazed skin and flowed down her chin and dripped onto her beautiful rack. She opened her mouth when I was almost finished cumming and took the remaining shots onto her tongue, giving me a great view of it slowly sliding back towards her throat. Once I was spent she licked me clean, gave me a smack on the ass and went to the bathroom with her brother's cum splattered all over her face and tits. "Ready to head out onto the slopes, get some last minute skiing in?" she asked. "Sure, I'll just go get dressed." Once we were dressed we went out skiing. We spent the whole day together and had a lot of fun like we usually do. I realised because of her friends presence we hadn't done that this year. We met up with Dawn and the three of us had a fantastic time, we had lunch together and then went skiing down some intermediate slopes for Dawn's sake. Around 3pm Dawn headed back to the house due to sore legs, she still wasn't as physically adjusted to skiing all day like some of us. Plus she said kneeling on the deck the night before didn't help. I was sore also but didn't wanted to get some more skiing done before we went home. Once Dawn left it was a good excuse for Paige and I to hit the more advanced runs. Some time later we were barrelling down one of the advanced runs when Paige lost her footing going over a small bump in the snow and fell flat on her face. I couldn't avoid her and tried to jump over, but ended up face planting also. We both sat up and dusted ourselves off, finding neither of us were hurt. Then we burst out laughing. It reminded me of our younger days when we were more daring and less skilled at skiing, we would tumble over each other like that a lot. Only this time Paige was a beautiful grown woman. I started to get aroused, sitting in the snow laughing with this vision of loveliness before me really seemed to get me going. "God damn, you're hot sitting in the snow like that." I told her. "Thank you." she replied, then we found ourselves looking deep into each other eyes until we seemed to come to a mutual unspoken understanding. Together we crawled off the side of the run until we were somewhat hidden behind some bushes. We both struggled with our snow pants and multiple layers. Soon my cock was exposed to the cold air and rapidly growing to its full size. Paige had her pants undone and they were soon bunched up around her knees, her underwear going with them. She turned away from me and bent forward to rest her elbows in the snow, facing the bushes that barely separated us from the main slope and exposing her ass and pussy to the freezing cold air. I had a good view over the bushes and up the slope. I could see everyone coming down the mountain, but hoped they couldn't see much of me with all the shrubbery around us. I inched forward on my knees towards my sister's waiting snatch and my pants and underwear dropped with the motion, exposing my ass, balls and upper legs completely to the elements. It was freezing, but my arousal stopped it from annoying me too much. I placed my still gloved hands on my sister's cold ass, lined my dick up with her lips and pushed forward lightly, bumping my cock head against her until it was directed downward and my shaft slid along her pussy, lightly rubbing her clit. She was already sopping wet and ready for my throbbing dick but I teased her for a moment longer by rubbing my cock along her slit as I watched the skiers coming down the slope ahead of us. Nobody seemed to be noticing us, or looking in our general direction, so I guessed we were mostly invisible to them. "Oh shit, fuck me already..." called Paige. She seemed to be struggling to keep her voice at a low enough level to not attract any attention to us. I did as instructed and plunged my throbbing cock between her lips, penetrating my sister and slamming my cock right down until my balls rested against the now cold skin of her legs. She cried out at the sudden penetration, but there was nobody close enough to hear at that particular moment. I paused for a while and savoured the moment, flexing my cock to press on her insides. I squeezed her ass cheeks between my gloved fingers and took a long deep breath in through my nose. The fresh cold air stinging my throat slightly. "Ahh, that's the stuff, nothing like some tight sisterly pussy. I've been hoping for this all week." I whispered to her. "Me too," she said, "Although I wasn't sure if I'd go through with it. Now hurry up and fuck me, I feel too exposed out here." I started to thrust my rod in and out of my sister's cunt with reckless abandon. All the waiting, the teasing of the past week. It felt like everything was just a tease leading up to this event, I couldn't stand it any longer and couldn't hold back. I gave her my all and pistoned my cock in and out of my sister as fast as I could possibly go. I watched my dick split my sister in half with amorous fascination as each thrust quickly brought me closer to orgasm. I could smell pine needles, it ticked at my nostrils but I ignored it as I pounded my sister. I knew I could last much longer if I wanted, but I couldn't stop myself from going all out. The intensity of fucking my own sister in public with freezing air hitting my ass was too much stimulation. I looked up as I approached my climax and scanned the slope while my hips continued ramming my cock into my sister's hot snatch. There was a couple across the other side of the slope heading down at a slow pace. As they approached our elevation they turned toward us and were coming closer. A lump formed in my throat, had they seen us? No they weren't looking at us, they were busy talking to each other as they slowly made there way down. Suddenly I recognised them. They were our parents. Our parents passed us by as we fucked. Paige couldn't see them, and there was no way I was going to make her aware. I continued slowly fucking my sister as our parents passed us, chatting loudly with each other. I paid no attention to what they were saying, I was busy hoping they couldn't hear or see us. They passed right by us, but then they stopped just down hill from our position. I almost panicked and my cock slipped out of Paige. I froze for a moment and Paige reached back and tried to reinsert my dick into her with her gloved, frost covered hand. She failed. "What are you doing? Hurry up..." she whispered. I remained frozen, waiting to see if Mum and Dad had heard. Soon I became clear that they hadn't, in fact they appeared to be kissing and paying no attention to us. I quickly felt for my cock which had softened slightly but was now almost completely hard again. The idea of my parents being so close while I fucked their daughter was a massive turn on now that I knew they hadn't seen us. I aimed my cock back at Paige and without taking my eyes of our parents reinserted it into her pussy and resuming fucking her. I refrained from slamming myself into her as I didn't want our skin to slap together like had been earlier, but I fucked her hard and fast regardless. Our parents continued making out, completely oblivious to their frisky children fucking each others brains out only 20 feet away. My orgasm quickly re-approached and rapidly overtook me. Paige reached her climax at almost the same time. She bucked against my cock as it erupted deep in her tunnel and I splattered her insides with hot cum. My toes curled of their own accord and I was practically paralysed as the waves of pleasure swept over me. I didn't think I could cum more than I have the last few nights, but I did. While I watched my parents making out nearby I pumped load after load of semen into my sister's snatch until it was squelching out the sides coating my balls and running down both of our legs. Just as my balls emptied and the semen stopped flowing our parents broke their contact and resuming skiing down the mountain, soon completely out of sight. I collapsed onto my sister's back and she collapsed into the snow as I let out a massive sigh of relief and contentment. "That was awesome." she said. "You have no idea." I told her. After a few moments rest we got back to our feet and tried to clean ourselves off. Our legs were coated in cum and there was even some on our bunched up ski pants. I quickly cleaned myself off as best I could in these conditions and was fully dressed again in no time. Paige was scooping cum out of her pussy and swallowing it before she wiped the cum off her clothes and legs and flicked it onto the snow. Once she was dressed we checked each other for any visible cum and then continued down the mountain. It was almost 5pm so we headed back to the house as the sun would be setting any moment and we had to be ready to leave at 6:30 when our parents would be coming by to pick up some of the girls so we could head home. As soon as we entered the nice warm house we both immediately stripped our clothes off in the entry way as our legs still had some cum on them and we felt dirty. My cock was hard again as soon as I saw my sisters exposed body and I began to wonder if there was something wrong with me. How much abuse could my dick take before it dropped off or something. I tried to ignore my arousal and headed for the shower but Paige beat me to it. I would have joined her but it was a rather small shower. So instead I headed back to my room to pack while I waited. I passed Paige, Dawn and Amanda's room and found the door open with Dawn standing there completely naked and one leg up on the bed as she rubbed moisturiser into her skin. There is something about that minxes hot naked body that simply drove me crazy. I tried to keep walking as I needed to get packed and ready to go, but I couldn't help but stop and admire those thick protruding nipples and sexy wide hips. I then remembered that there was something I wanted to ask Dawn also, so I entered the bedroom. Before I knew what I was doing I had her up against the back wall with her ass sticking out and my dick lodged in her pussy. We fucked like only horny teenagers can. Then Amanda walked into the room. "Oh Amanda," I said to her, "could I have a minute with Dawn in private please, there is something I want to talk to her about." "Sure," replied Dawn, "you'll have to stop fucking me for a moment though if you want me to leave." I was confused for a moment, my horny brain didn't have much blood to work with, it was all in my cock. "Oh shit, you're Amanda?" I said rhetorically. "I'm fucking the wrong person! Unbelievable." "Haha." laughed the real Dawn. "Sorry to disappoint." said Amanda while I continued to plough her pussy with my cock. "No no, I didn't mean it like that. I'm very happy to get to fuck you too. I just thought you were Dawn for some reason." "No offence taken. Happens all the time. Well not the fucking but you know what I mean." "So what did you want to talk to me about?" asked Dawn. "Well now seems like a strange time to ask, but what the hell. I was wondering if you'd like to go out with me sometime?" "As in, on a date?" She asked. "Yeah." I said, somehow nervous even though I was plugging her sister as I said it. "Holy shit, this is a weird situation." said Amanda as she pushed her ass back against me to get as much cock in her twat as she could. "Of course I will." said Dawn, "I was planning to ask you if you didn't say anything. I've had a crush on you for months and was waiting for this week to get to know you more first." Then Dawn approached us and kissed me deep and passionately. I held her head in place as I pumped into her twin sister harder and faster, pinning her against the wall. I felt my orgasm approaching as I thrust my tongue into Dawn's mouth and played with hers. Then my climax ripped through me and I shot my load deep into Amanda's cunt. I held myself in place, pinning her against the wall as I ejaculated inside her and made out with her sister. When I was spent I finally broke the kiss with Dawn as I pulled my dick free from Amanda with a sloppy pop. "You're an incredible kisser," said Dawn, "You really know how to turn a girl on. Although usually you pump a girl’s sister full of semen after you take her out for dinner, not before." The three of us cracked up laughing at the absurdity of the situation, then Dawn sucked my cum out of her sister as if it were an everyday occurrence and we made plans for the following night. We were going to a local restaurant then a movie. Pretty traditional. I wondered if she puts out on a first date. Paige entered the room right as I was leaving so I went and had a quick shower, followed by quickly packing all my things. Our parents arrived at 6:30 sharp and after some chit chat we set off on the lengthy car trip home. The girls played silly car games the whole way home, but I didn't participate. All I could think about was my date with Dawn which I was inexplicably nervous for and whether or not Paige would let me fuck her again when we got home.
