One day, her witnesses Aoi giving her boyfriend a blowjob in her room, and does something out of the ordinary…

In the quiet of her room, Aoi kneels, her lips wrapped around her boyfriend’s length, her eyes closed as she savors each thrust. Suddenly, the door creaks open. Her roommate, Lille, steps in, her breath catching at the intimate sight. Instead of turning away, Lille approaches, her fingers tracing the curve of Aoi’s neck. Aoi pauses, a mix of surprise and anticipation in her eyes. Lille leans in, her breath hot against Aoi’s ear as her hands find the hem of Aoi’s top, slowly lifting it. The boyfriend, a silent participant, becomes an observer as Lille joins the scene, her touch both possessive and inviting, intensifying the unexpected moment.
