Bored teens, left behind after a late-night study session, find themselves alone and horny. One, a busty blonde, starts fingering herself under the table, her moans echoing in the empty classroom. Her studious friend, a lanky brunette, notices and can't help but join in, pulling out her own vibrator. They exchange shy glances, then eager smiles, as they masturbate together, their young bodies writhing with pleasure.
