the first time it happened was in a sex club, there were no private cabines so everything was public, i was still a top those days, but a guy with a big dick fucked me for the first time, everyone could see me, even my BF was watching how i got pounded by a stranger.
the last it happened in a gay sauna, started with a guy in the mirror room, during the suck and fuck you can see other men watching and it makes me only more horny.
