Oh boy is this your lucky day or what? Your stepsister has two girlfriends over for a slumber party. Parents out of town, time to have some fun. You poor some drugs in their drinks. After a while they get real horny. They don’t really notice what is going on. But they start rubbing themselves and look at each other with wild eyes. They start kissing and then all bets are off. They look at you and ask you to join them. Whip out the cock and give them some. Sure you will.
