Dirty Schoolbus

When a guy shoves a twinkie up a girl's asshole and then ejaculates on it. Afterwards, he gets another girl to eat the twinkie out of the other girl's asshole while on a schoolbus. The girl with the twinkie up her asshole then proceeds to finger her asshole and then eat the sperm and twinkie from her fingers.

Example:

Kid: Wanna get a dirty schoolbus?
Girl with tight asshole: Hell yeah! I love twinkies up my asshole!
