In the heat of an argument, siblings Michelle and her brother find themselves locked in a stifling closet. As they struggle against each other, their bodies press close, igniting an unexpected spark. Michelle's breath hitches as she feels her brother's hardness against her thigh. They freeze, eyes locked, before Michelle tentatively reaches out to touch his throbbing cock. He gasps, and she takes that as encouragement, stroking him until he's rock hard. Their breathing ragged, they stumble through an awkward, frantic coupling, their taboo lust overwhelming all else.
