Drawing session’s hard end

Fragile blonde Pretty Di is a beginning artist. She needs a model to master her people drawing skills. Her boyfriend doesn’t want her to look at other naked men, and this is why he offers his help. He takes off his clothes and covers his hips with a blanket. Somewhere in the middle of the session, Pretty Di notices a movement under the blanket. She even puts on her glasses to make sure she’s not mistaken. Yes, the dude has a huge hard-on, and that means the drawing session is over.
