A few years ago my wife and I were newly married. I had taken a job on the west coast. We had moved away from our families in the east. With the new job I was making plenty of money so my wife was able to stay home and enjoy life. As the years past our family started to grow. We now had two girls and wanted very much to move back to where our families were.



This presented a problem. We ended up selling our house on the west coast at a substantial loss, due to the market conditions. We decided that we would move in with my wife's parents until we could save enough for a loan on a new home. Luckily they are pretty wealthy and had a large home.



My wife has two sisters, she is the oldest. The middle one, Sharon, moved out of the family home a few months back which just made it us and the youngest, Shelly. Sharon was 26 at the time and Shelly was 23. Sharon was the typical east coast party girl, going out to the bars and clubs every weekend and having fun. Shelly was a little more reserved, staying in most nights, although she did have a boyfriend named Cody who didn't live too far and spent most of his time at the family home with Shelly.



It was summer when we moved back, and it was a scorcher. Most days the AC ran all day and night. Everyone pretty much hung out by the pool during the day, including my wife's parents. Shelly had fairly pale skin and was always trying to get a good tan, at the same time she did not appreciate tan lines. So there were a lot of skimpy bikinis being worn around most of the summer. Luckily she could pull it off, she was a 5'7" petite blonde with a small C cup and an ass to die for! Seeing her in a thong bikini was a sight for sore eyes.



I really didn't know the family all that well when we moved in so it was a learning experience. I spent most of my time reading outside while everyone was hanging out in the pool, I wasn't much of a swimmer at that time. One day I was home hanging out as usual and Shelly comes in with her boyfriend to go into the hot tub, they walk by and say hi and continued to get in the water. Before I knew it they were all over each other, making out, feeling each other up. I could see from the pool deck that Cody had his hand in her bikini. I just watched, I didn't want to interrupt, I was enjoying the show too much. Finally just as they came up for air Cody's cell phone rings, it was his boss, he had to go back to work on an emergency. He got up out of the pool and was sporting a very hard cock that was easily visible through the thin board shorts.



I jumped in the pool to cool off before anyone noticed how hard I was getting. I swam over to the jacuzzi hot tub area and jumped over the wall that separated the two and joined Shelly. You could tell they were both left hanging, he left with a hard-on and her nipples were poking through her padded bikini top. I slid over to her side and asked her how she was doing she responded telling me how horney she was and that she couldn't believe he left her hanging. I told her that I could not believe it either. I noticed something then that I hadn't before, she had a hand under the water in her bikini rubbing her pussy as we were talking. I decided that I would be blunt with her and I asked her if she was masturbating. And she responded by telling me that she was reliving a little tension and that I should do the same. Continuing on that bold streak I said why do we go upstairs and do it in earnest then. She called my bluff and got out of the pool immediately. Grabbed a towel off the rack and I followed her to her room on the third floor. She quickly dried off and removed her bikini right in front of me. She told me to take my shorts off so I did and she started rubbing herself again. I was impressed, this reserved girl was now masturbating in front of her only brother-in-law.



At that point I started to stroke myself with pride. I was a well built guy at 6' and muscular but didn't overdo it. I was proud of my package too, I even went once every other week to a men's salon and had it groomed by a pro. It is about 8" long and fairly thick. Shelly laid down on the bed and I laid next to her we were both going at it now and had made no real physical contact until I decided I would see what one of her titties felt like. I rubbed and pinched her nipple as I stroked it, meanwhile she is finger banging herself and rubbing her clit.



I can tell that she is going to cum any second so I get ready myself. She cums loudly and shortly there after I shot my load all over my stomach. She looks over at me and dips a finger in my hot cum and puts it to her mouth and smiles. I started to get up to leave and she told me "same time tomorrow". I just smiled.



The next day we were home alone again, and again Cody was there. I figured our little jack off date was probably cancelled since he showed up. Just as I was getting ready to go upstairs to my room she asked if I would stop by hers, I thought that was strange but went with it. Why I went to her room her and Cody were already in there kissing, she was topless and his pants were undone. Once she noticed I was in there she asked if I wanted to join the party, I said okay, but a little nervous since Cody was there, I was not accustomed to being around naked guys with hard-ons. Shelly sat on the bed and looked at both of us and told us to strip, I started to take all my clothes off and Cody was already done, he just had a pair of shorts on, apparently with no underwear. Finally we were both naked and semi-erect. Naturally we checked out each others packages, his was as long as mine but not really as wide. He also shaved his bare while mine still had some hair on top. I assumed at that point that he was completely hairless.



Shelly dropped to her knees and took my cock into her mouth immediately. She used her other hand to jack off her boyfriend. She switched off a few times, I was really hard and so was Cody, both enjoying ourselves very much. She then switched to sucking my cock and surprised me by shoving his in her mouth at the same time. This was the first time that my dick had ever been in contact with another mans, and I don't have any gay tendencies at all at this point. I let it happen and I was glad I did, I loved seeing her mouth get stretched like that, it was such a turn on.



Shelly then laid back on the bed, now completely naked and told one of us to shove a cock in her, Cody obliged and I watched and played with her clit a little, which she liked. My hand was periodically coming in contact with his cok, for some reason neither of us minded. I eventually moved up and straddled her face too put my cock in her mouth. She happily took it, trying her hardest to deepthroat it. Cody then did something that surprised both of us, he pulled out and came on Shelly's chest, almost without warning. So knowing that she wasn't quite done I stepped in to the freshly fucked pussy and started fucking my sister-in-law's tight pussy. I flipped her over to get more leverage and she started to suck Cody off to get him hard again while she came for the second time. I couldn't help but admire her from behind, she had a great body, tone, tan, even a nice asshole. Plus it was all completely hairless!



Shelly's mouth is tired of cock chugging so she spits out her boyfriend and starts barking orders. She tells me to start rubbing her asshole, which I gladly do and then some. Then she tells me to keep Cody hard, which confused me at first so I asked her what she was talking about and she said to keep his dick hard, she wanted him for her butt in a little bit. Then I realized she expected me to touch this guys cock, and I am not really that kind of guy. I decide to do it anyway so I don't screw this situation up. I placed my hand on his semi-erect, wet cock and start pumping it as she rides me. As this is going down we are all caught up in the moment and Cody reaches under grabs one of his girlfriends luscious full tits and brings his hand back up, on it is some slimy stuff, before I know what is going on he is shoving two fingers full of cum from earlier into my mouth. I definitely had never tasted another's cum before in my life but for some reason it made me hard and ready to cum myself. I informed Shelly of this and she told me to pull out. So I did, as soon as I did Cody dropped down and took me into his mouth and was sucking my cock feverishly. She is so turned on by this that she cums also with a finger in her ass. I am a little stunned so i didn't cum right away like I thought so he had to work a little, but I was in the zone, I had tunnel vision, all I could see was this other man with my dick in his mouth and I was as hard as ever. Shelly moved in behind me with her pussy soaked hand and slowly started playing with my asshole. Within a few minutes she had two fingers in milking me into her boyfriends mouth.



I came hard, shot a ton of spunk into this dudes mouth. He pulled up and started making out with his girlfriend, swapping my seed back and forth between them. His dick was at full mast at this point so instead of just standing there I spit on my fingers and started to rub Shelly's asshole. Within moments I had two fingers buried inside of her. Knowing what was coming next she promptly got on all fours, I grabbed her boyfriends cock, ran my tongue on it for some quick lubrication, spending a surprising amount of time on the tip, and guided it with my hand into her waiting asshole. It took a few moments, but once the head got in all the way he was able to fuck her in earnest. At this point I scooted myself under her, with my face pointed directly at her pussy and started licking, she got the hint and took me in her mouth again. I was getting very turned on eating her pussy, tasting our combined juices, and occasionally delving into the ass area and licking the underside of Cody's cock. I couldn't believe what I was doing, but I was in heaven!



Shelly was getting close now, I could taste it in her pussy. I turned around and put my mouth next to hers and my cock near her pussy. I reached down and started rubbing the tip around her wetness, teasing a little while making out with her. Finally I stuck it in and could not believe that her pussy was still so tight after so much fucking today. The double penetration turned her on so much that she came within a minute or two of fucking. Neither Cody nor I had cum a second time yet so while he was still in her ass he grabbed my cock out of his girlfriends pussy and pulled it under him and started rubbing his own asshole with it. I felt the tip rub against something hard and realized he had a buttplug in this whole time. He reached back with his other hand pulled out the buttplug and started to sit down on the head of my cock. I was still very hard and enjoying myself a lot so I went with it. I thrusted up a bit and 'popped' into him. We then got into a rhythm of me fucking him and him fucking her. It didn't take but a few minutes of this before we both came, I shot my load into his asshole while he shot his into Shelly's.



Everyone was exhausted and I was feeling a little embarrassed about what I had just done. We were all satisfied very much though.
