On holidays a few years ago I’d become friends with a group of guys around my age and we’d mess about together but one day we in one of their hotel rooms sitting on the balcony watching the hot girls below,now I noticed my twin sister walk up to the pool dive in and swim back out to then go and lie on chairs beside the pool in a tiny thong bikini and took her top off but lay on her stomach,the boys loved this and eventually we all had our cocks out wanking over her but I never told them who she was I just wanked along with them eventually cumming over the sight of my sisters ass and watching them do the same. I didn’t spend much time at the hotel after that just incase they found out but it was still an amazing experience.
