Unbeknownst to her brother, Michelle accidentally walks in on him adjusting his prominent bulge in the bathroom. His thick, veiny cock catches her eye, and she can't help but imagine it filling her hungry pussy. Their eyes meet, and the tension is palpable. She tentatively reaches out, her small hand wrapping around his shaft as he grows harder. He groans, leaning into her touch. They're interrupted by a knock at the door, forcing them to quickly separate, leaving them both breathless and yearning for more.
