Maruta W, a gorgeous Japanese wife, and her husband, Maruta H, indulge in their cuckold fetish every night. Maruta W, a clear system slut, teases her husband with her dirty talk, "Use me tonight, like a toilet." She loves the feeling of being stuffed full of strangers' cum. Tonight, a new lover calls her, and she eagerly answers, inviting him over. Her husband watches, hard and frustrated, as she sucks and fucks the other man, begging him to fill her pussy with his hot cum. The night ends with Maruta W, satisfied and coated in another man's creampie, leaving her husband to clean her up.
