A mischievous brother tests his sister's boundaries with a gay roleplay, feigning desire for her. He strokes his cock, gazing at her with fake longing, and she can't help but feel a thrill. "What are you doing?" she gasps, her heart pounding as he edges closer, his hot breath on her neck. He grins, "Just exploring, sis. Aren't you curious?" She swallows hard, her pussy dampening, as she considers giving in to this twisted, yet tantalizing charade.
