I have been seeing this girl for just over a year, she is very randy and has been into all sorts of stuff, she was telling me about an ex who during a swapping session ended up rubbing his cock with the other bloke. She really liked it and wanted to try it out. Anyway a bloke at her gym had been chatting her up and she hinted on a threesome, he was keen she told him he would have to rub cocks with me and he was not put off. Anyway I agreed as I would also like to see her get fucked, he comes around Friday and we have a few drinks, he is in his early thirties we are a bit older, anyway we end up in bed and we both kiss and grope my girlfriend, he fucks her and I watch and wank, the after a while she gets us to lie very close so our ball bags touch and she grabs hold of both of our knobs and i get massive hard on and so does he, she then rubs our cocks together and sucks them both until I come very quickly and she finishes him off. He fucks her later and I watch and then she gets us to stand close and fight with our cocks, she gets behind me and literally starts whacking his dick with mine and then she wanks us both off again.
They are bot really keen to try all this again and he has said he can bring a girl with him, my partner was truly made up and the next night we had great sex while she talked about it, and she cant wait to try again. I liked it but I wonder if she will want me to go further, but I feel committed, still the sex was great as was the double blow jobs, I will have to see what happens next.
