Unsupervised Siblings' Steamy Hour

With their parents out, horny siblings Michelle and her stepbrother find themselves alone and bored. Initially, they retreat to their rooms, Michelle fingering herself under the covers, her stepbrother jerking off in the shower. A heated argument ensues when he catches her, but later, they make amends, masturbating openly in front of each other. Michelle's eyes widen at the sight of his thick, straight cock. As they're about to act on their mutual lust, a sudden noise forces them to stop.
