Former swinger here. Had sex with two bisexual women and what anal with one while the other female was eating her out. When she started cumming, her ass clenched down on my cock and I couldn’t hold back, I came inside her ass uncontrollably. I’d describe the sensation as being better than the best deepthroat I’ve ever had, wet, tight and warm. She mentioned that having my cock inside her ass as she climaxed gave her one of the most intense orgasms she ever had.
