Intense orgasms oftentimes are achieved during the most heinous acts;. I dare you to use your imagination. One example of such is having sexual intercourse during asphyxiation. Sharing neurotic thoughts with strangers, really gets me excited.
I am now thinking of the time when two submissives and I had erotic sex, during a snuff session. They were both so frightened. I wanted to make things exciting, so I handed each of them a plastic bag to put over their heads. I secured the bags around their necks with duct tape and ordered them to have anal sex together. I watched and masturbated. Funnily enough, though they feared for their lives, neither of them had any problem achieving erections and cumming extremely hard inside of each others assholes. I finally took a sharp nail and made an opening in their bags for air to come in, but it was too late.
