Introduction:

Could a foursum be on the cards?
Ali is my sister in law and at 37, 5 feet 6 tall, size 12 with strikingly natural black bobbed hair, she is a very normal, shy mum of three. Our two families have grown up together like a lot of families, spending Christmases and other holidays at each other's homes. Ali and her family came to stay with us on their way back from their Sumer holiday this year. The timing was perfect as we have just moved into a new house and I really needed Dans help (Ali's husband) finishing off a few jobs around the place. As the jobs were ticked off one by one and the weekend approached, Claire (my wife) and Ali started planning a very long over due housewarming party.

The house was looking even more amazing than we could of imagined as it filled with family and friends. The drinks flowed and Claire looked incredible, with her short blonde hair and tight black dress showing off her petite size 8 body and 32a breasts, there wasn't a guy in the house that had not noticed her and wondered if her long slim legs were dressed with nude holdups or tights (she always wears holdups, a delight I had enjoyed earlier in the day as she dressed herself after a short but intense love making session)

The party was in full swing and there seemed to be as much flirting going on as dancing (blaming the hot summer nights) and as I made my way upstairs and opened the bathroom door, I was taken aback by Ali sitting on the toilet seat (still dressed) with her head in her hands looking very tipsy. I apologised at first not realising she wasn't busy and it was only when she didn't reply that I went back and checked on her again. Ali replied but seemed to slip forward and as she did I instinctively caught her in my arms and stood her up, she clung onto me and said that she needed to lay down as she didn't feel well. Ali and Dans room was opposite the bathroom so it wasn't long until Ali was sat on her bed and asking me to unzip her beautiful floaty summer dress. The zip open very easily and as it did and Ali stood up her dress fell to the floor. I had always wondered about Ali's body and truth be told I had fantasised a few times about her when I had been alone and now here she was standing with her back to me in just sheer cream full knickers and a matching bra. Ali turned round and looked me up and down before asking me if her body was as nice as her sisters? Ali's body was a bit fuller than Claire's but she looked incredible for it, even more than my fantasy had aloud me to believe, so as I took the opportunity to look Ali up and down my cock quickly hardened, something that had not gone unnoticed by Ali. As my eyes drifted away from her midriff and down to her hips my heart and cock leapt as there, shyly hiding behind the thinnest vail of sheer cream panty was a very full but trim and beautifully tidy black pubic bush, a real contrast to her sisters shaven blonde pussy. My swelling was now complete and very obvious so as I approached Ali and she grabbed at my hardness it was only a few seconds before we kissed open mouthed and fell backwards onto the bed.
Ali took my hard swollen cock out as we kissed and with no resistance her panties came off, she opened her soft thighs and just a few seconds later my thick cock was at the wet swollen entrance to her pussy. We both paused for a second, then as we pulled towards each other I felt her warm, wet, tight pussy grip my cock and a second later as we paused, we held each other close and looked into each other's eyes, enjoying that most intimate moment of being inside someone for the first time. As we enjoyed each others bodies, her bra came off and Ali's 34b breasts looked stunning as I kissed and touched my way round my sister in laws womanly body. Ali was fast becoming more than my self control could cope with and as my body tensed and the wave of orgasm flooded down my body and out into Ali's beautiful pussy, Ali's own orgasm gripped her and we came together, entwined in a hot passionate embrace.

Ali and I got our selves dressed, straightened up our clothes and hair, then Ali went back to the bathroom and I went downstairs to find Claire. I gave Claire a deep and passionate kiss and as I did so Ali came into the room and did the same to Dan. As they kissed I felt my hardness swell again knowing what we had just done. as Ali and Dan kissed Ali looked over at me, I had no idea that my wife's shy sister was such a wonderful lover!

A few hours later the party had finished and Claire and I were finally in bed after what had proved to be a very eventful and successful party. Claire and I kissed with increasing passion my hand drifting down between her thighs, her legs opened for me and two fingers slipped comfortably into her warm wet and waiting pussy. It wasn't long before Claire had my hard cock in her mouth and I watched as she worked my shaft up and down so expertly like she had done for the past number of years. Claire straddled across my face and as she did I expertly licked her very wet pussy enjoying and savouring her very unique and lovely taste. Claire climbed onto my cock and after a few moments and several positions once again I collapsed in a heap having shared an orgasm for the third time that evening with both sisters. As I held Claire in my arms and we both glowed in the aftermath of our wonderful evening and amazing sex, it became very obvious that Ali and Dan were also having sex right at that moment. I smiled as I asked Claire how she felt knowing what they were doing, Claire replied that it turned her on immensely knowing that Dan was hard! She asked me how I felt about Ali, I replied I felt exactly the same..

Thanks for all the comments, just a few observations to make if I may 1) I'm not a professional writer, so if sharing my experience is not what you are expecting then I'm sure you'll find professional sites more to your taste. 2) This experience really happened so adding or subtracting content is just not correct (as much as I'd like too) but thanks again for all the comments.

Made out with my sister in law once. I think I could have taken it farther, but I hesitated and the window of opportunity closed on me.
