Locked away in their parents' house, two siblings find themselves alone and horny. The brother, a strapping young man, can't help but think about his sister's tight body. The sister, a petite brunette, has been catching her brother checking her out and can't deny the thrill it sends through her. They start off innocently, playing a game of truth or dare that quickly turns heated. The dares become more and more risqué, until they're both naked and panting, their bodies yearning for each other. The brother takes the lead, pushing his sister back onto the bed and spreading her legs. He teases her clit with his tongue, making her squirm and moan before sliding his hard cock into her tight pussy. They fuck hard and fast, their bodies slapping together, their moans filling the empty house.
