Brother's cock drives sister wild, she can't help but masturbate.

Bored and horny, the sister finds her brother's cock on full display while he's changing. She can't help but stare, her pussy growing wet at the sight. He catches her watching and, instead of being embarrassed, he starts stroking his thick shaft right in front of her. She's torn between disgust and desire, her hand creeping down to rub her clit through her panties. They lock eyes, the tension palpable, as they both masturbate openly, their breaths growing ragged. Just as he's about to cum, she bolts from the room, leaving him panting and unsatisfied.
