I don't know why they call it punishment, I love being tied down having my ass whipped without Mercy, then having a dick or a strap-on rant into my ass as hard and as violently as possible, while I'm laying near helpless and have to take it
My last girlfriend would peg me, and she knew I wasn't just bisexual. She knew I'd be getting some real cock inside me, and I have. After our relationship ended, I never went back to pussy because now I have a faggot pussy that has been railed by my gay lover.
