A sister and brother, their relationship strained by years of sibling rivalry, find themselves alone in the house one afternoon. Bored and restless, they turn to each other for comfort, their bodies betraying them as they begin to masturbate in front of each other. Michelle, her pussy dripping with desire, watches as her brother's cock grows hard and thick. She can't help but imagine it inside her, filling her up. As they grow bolder, their mutual masturbation turns into a heated session of fucking, their bodies slapping together as they chase their climax. But just as they're about to come, they hear their mother's voice, forcing them to hurriedly separate and pretend nothing happened.
