Expressive, intensely sexual 30-year-old married woman Yokomine Megu makes her porn debut. The former receptionist at a major corporation risks betraying her husband in her first affair, revealing desires she could never confess to him. She takes another man's cock deep in her throat and pussy. Tears fill her eyes after her first extramarital fuck—whether from guilt or the thrill of finally living out her fantasy, she does not say. Instead, she goes on seeking even stronger stimulation through more affairs.
