Bored and restless, a sister and brother find themselves alone in their cramped apartment. As they bicker, the brother's eyes can't help but wander to his sister's curves, her nipples hardening under her thin top. She notices, and a game begins. She teasingly plays with her hair, her breasts, her pussy through her shorts. He responds, his cock tenting his pants. They're both curious, both horny, and the tension builds as they circle each other, the air thick with unsaid words and unfulfilled desires.
