Siblings convene in a dimly lit room, the air thick with anticipation. The brother, hard and throbbing, strokes his length as the sister watches, hungry and eager. He grunts, his pace quickening, and she opens her mouth, ready to receive his hot, sticky offering. His first spurt lands on her tongue, and she swallows greedily, her eyes locked onto his. She guides his pulsating cock, milking every last drop, before licking her lips clean.
