My house has become a hangout for three popular girls from my class, and they find the porn I've been hiding, forcing me to watch it with them. They're clearly amused by my reaction and escalate things, saying things like, "Jerk off like you always do lol!" They get carried away with their playful imitation and start using my dick as a toy! At first they were just messing around, but then the three of them get serious...!?
