When I ran away from home, I was picked up by two slutty sisters from the neighborhood. "You can stay at their house, but in return you have to never say no to sex," was the deal, and they kept having sex with me whenever I was at home. The older and younger sisters came over in turns, and when the older sister was having dinner with our parents, I had sex with the younger sister. When the younger sister was watching our parents in the living room, I had sex with the older sister. They kept coming over to my room in turns. Thanks to them, I was always empty of sperm.
