[mosaic book] I'll be your toilet

An eager young woman with twin-tails agrees to become a man's personal toilet, offering herself for urination and intimate acts in a cramped bathroom setting. She strips down, embraces the role of a prostitute, and revels in the sensation of being used as a receptacle for his bodily fluids, while the man, dressed only in a simple shirt, dominates the encounter with confident, teasing commands. The tension builds as she balances embarrassment with pleasure, culminating in a climactic exchange where she invites him to fill her once more, promising future encounters.
