Go into the community bathroom
From Create Your Own Story
You walk into the bathroom. It's completely empty, so you go to hide in the showers. A few minutes pass and a few other guys show up, confused you ask them what they're there for. One man answers, "We're here for the gangbang, just like you."
You find out that every Saturday morning, a few girls come to the showers to get fucked by a dozen or so guys. The first girl to come in is the well known school slut, Tina. You've walked into a bathroom stall where she was giving head at least three times, once she even offered her services to you. She starts by getting fucked by one guy while she sucks off another. The guy fucking her gives her a creampie, and the guy getting blown switches to her pussy. You realize your expected to cum in this girl with ten or so guys cum already inside. Eventually she gets to you. You were hesitant but you find out that cum is a really good lube, and actually enhances the experence quite a bit. Before you cum another girl comes in. Shes a tall redhead with massive tits. She pulls tina off of you, and starts licking cum out of Tina's pussy. As gross as it is it really turns you on. The redhead starts sucking you off as Tina moves on to the other guy. You blow your load all over her face, getting in her eyes and hair.
Exhausted, you clean yourself up and head back to your dorm room. You know what your doing on saturday mornings from now on.
The End.
