The boyfriend, unsuspecting, leaves his girlfriend alone with her 'study buddy' for the afternoon. The friend, a tall, muscular Argentinian, can't take his eyes off her ass as she bends over the books. She notices, and a game begins. She teases him, her voice dropping to a sultry purr as she asks him to help her with her 'problems'. He can't resist, and soon, he's burying his face in her wet pussy, lapping at her clit until she's squirting all over his face. She returns the favor, gagging on his thick cock before they invite the boyfriend in, eager to show him what they've been 'studying'.
