She tentatively reaches out, her fingers wrapping around his shaft as he gasps at the unexpected touch. Their hearts race as they explore each other's bodies, the taboo nature of their actions only serving to heighten their pleasure. Michelle's pussy drips with lust as she jerks her brother off, her own clit throbbing with need. She can't help but imagine what it would feel like to have that massive cock plunging into her, stretching her tight cunt. As their passion intensifies, they struggle to remain quiet, their bodies writhing against each other in the confined space, their moans muffled by the closet walls.
