Sumire is a married female teacher, but recently her husband and her have frequently been in conflict. This time, the school organized a picnic for the students, and Sumire and the vice principal were assigned to scout the location. Since there was only one room left in the lodge, she and the vice principal had to share a room. Seizing the opportunity to be with the beautiful and alluring teacher, the vice principal deliberately got Sumire drunk, causing her to quickly lose consciousness. When she woke up, she found herself being 'invaded' by the vice principal. Nevertheless, with his skilled techniques and sexual experience, the vice principal quickly conquered Sumire. Up until now, she had only made love to two men, and it had been a long time since she had been intimate with her husband, which unleashed all the sexual desire that had accumulated over time. The pleasure the vice principal provided ignited her inner desires; she had never experienced this feeling before. Throwing away the teacher's morality, the married woman immersed herself in sexual pleasure over and over again. Sumire exposes her most embarrassing appearance to him, letting him in her uterus, wanting to be his own woman!
