Painting pumpkins
When you go to a girl's house in the fall and end up covering her butt in cum like it's a famous painting
He told her it was a surprise party, but it was just him and his cum on her butt.
She came home from trick or treating and found a whole mess of cum on her backside.
He said he was bringing a pumpkin, but it was just a bag of cum and a lot of attitude.
