Michelle and her stepbrother find themselves alone, bored, and increasingly aroused. She retreats to the bathroom, her fingers dancing over her clit as she imagines him walking in on her. He does, catching her mid-act, and they share an intense argument. Later, they reconnect, masturbating openly in front of each other, their bodies aching for touch. Just as they're about to cross the line, an unexpected intrusion forces them to halt their passionate encounter.
