Group sex
I've had one-on-one sex many thousands of times, I've had two at a time too, but proper group sex is in a different league, it's the right kind of exciting action. Three or more is awesome, I really enjoy that. That's why I sometimes enjoy a good group of guys with nice dicks, who fuck me over and over again, and then gradually fill me with cum or suck me from head to toe. The more dicks and cum, the better and the more it turns me on...
