Naked student in class

A dark-haired student sits at a desk in a classroom, his shirt slowly slipping off his shoulders as he leans back, fingers tracing his own body. The blue jeans cling to his thighs while his hands explore, first his crotch, then his head, then the desk beneath him. By the end, he’s fully exposed, legs spread wide, shirt discarded, the classroom’s empty chairs and desk the only witnesses.
