Clad in only their underwear, Michelle and her brother find themselves alone in the house, their hormones raging. Michelle, her nipples hard against her thin bra, watches as her brother's boxers tent, revealing his growing erection. He catches her gaze, his cheeks flushing. Emboldened, Michelle licks her lips, her hand reaching out to cup his bulge. He sucks in a breath, his eyes fluttering closed as she explores his length, her touch gentle yet insistent. Their bodies press closer, their breaths mingling as they succumb to their taboo desire.
