Later, they find themselves alone and naked, Michelle's eyes drawn to her brother's throbbing erection. She tentatively reaches out, wrapping her hand around his shaft, feeling it pulse with life. He gasps, his hips bucking slightly as she begins to stroke him. Their eyes meet, full of lust and fear, as they cross the line of no return, their bodies aching for each other's touch.
