In the dim light of their shared bedroom, Michelle and her stepbrother find themselves alone, restless, and horny. Michelle's hand creeps beneath her pajama shorts, fingers brushing against her slick clit as she bites her lip, trying to suppress her moans. Her stepbrother, awakened by her quiet whimpers, watches her with growing lust. He strokes his hardening cock through his boxers, eyes locked on Michelle's writhing form. Boldly, he joins her, their mutual masturbation session escalating into a heated exchange of lustful glances and whispered fantasies.
