Yuko downs a potion and becomes an invisible dominatrix free to indulge every urge. At a bar, she grabs a patron’s hand and forces him to fondle her breasts before rubbing her wet pussy against him. She urinates into his glass and secretly makes him drink it, smothers his face with her pussy, finishes him with her mouth and swallows his cum. She then moves to another patron and jerks him off to orgasm, gleefully playing with every cock she finds before the story continues in Part 2.
