In the dim light of their shared room, siblings Michelle and David find themselves alone and restless. Boredom quickly turns to curiosity as they catch each other's gaze, lingering too long on forbidden territories. Michelle's fingers trace circles around her hardening nipples, while David's hand strays to his growing bulge. They tentatively explore their bodies, eyes locked, until a knock at the door breaks the spell. Later, they reconvene in the closet, desperation and desire overwhelming their inhibitions. Michelle's tight pussy clenches around David's thick cock as they rut silently, their ecstasy muffled by the thin walls.
