In a cramped, dimly lit attic, Michelle and her brother seek solace from their strict religious upbringing. As they huddle together, Michelle's hand finds its way to her brother's thigh, her touch igniting a spark. He grows hard beneath her fingers, and she can't help but explore further, stroking his length through his pants. They exchange a guilty look, knowing they're treading on forbidden ground, yet unable to stop. Michelle's breath hitches as she frees his throbbing cock, wrapping her lips around it, tasting the salty pre-cum. Her brother, torn between lust and guilt, allows her to continue, his hips moving in rhythm with her eager mouth.
