Antonio Mallorca sets up a tantalizing prank for his unsuspecting girlfriend. He brings home a lifelike Tantaly doll, identical to their pink-haired, big-titted neighbor Britney. As she walks in, Antonio, already rock hard, encourages her to 'fuck the doll' to satisfy her curiosity. She hesitates, but Antonio's persuasive words and the doll's realistic features prove too tempting. In a heated doggystyle session, she rides the doll, moaning and grinding, while Antonio films, ready to reveal the truth later.
