Sumire is a married teacher, but recently the couple has often had conflicts. This time, the school organized a field trip for students, and Sumire and the vice principal were sent to inspect the scene. Because the motel only had one room left, she and the assistant manager had to share a room. Taking the opportunity to be with the beautiful and seductive teacher, the vice principal deliberately got drunk, quickly making Sumire drunk without knowing anything. When she woke up, she found herself being overfed by the vice principal. However, with his skillful technique and sexual experience, the assistant quickly conquered Sumire. Up until now, she had only had sex with two men. She had not had sex with her husband for a long time, so the desire that had accumulated for so long was released. The feeling of happiness brought by the vice principal aroused a desire inside her, something she had never felt before. Rejecting the teacher's morality, the married woman again and again indulged in sensual pleasures. Sumire exposed her most shameful self to him, letting him ejaculate into her womb, wanting to become his own woman.
