Locked in the house, Michelle's curiosity piqued by her stepbrother's late-night activities, she peeks into his room. Caught mid-masturbation, his thick cock in hand, they freeze. Embarrassment turns to desire as Michelle's eyes linger on his size. They share a look, and she tentatively touches his dick. He groans, pushing into her hand. Their taboo lust ignited, they clumsily explore each other's bodies, Michelle's tight cunt dripping, her stepbrother's cock throbbing. They're interrupted by their mom's voice, leaving them breathless and yearning for more.
