Tsukihi, a junior office lady in the same department, is beautiful, has a good figure, and is the Madonna of our company, with many fans among our clients. However, she was already a married woman when she joined the company because she got married as a student, so she is a flower out of reach to everyone. Recently, we started working together on the same project, and we are able to work together. She is friendly and considerate, and I have completely fallen in love with her. She seems to have trusted me as a senior at work, and one day she invited me out for drinks. As we got drunk, we started talking about marital relationships, which I don't usually get to hear, and she said, "I have sex with my husband," "My husband is completely passive, and I'm not satisfied with his sex, which is too ordinary," "Before we got married, my sadistic boyfriend trained me in anal sex," and "I don't cheat because it would be bad for my husband." Just when I was about to lose control, excited by Tsukihi's drunken talk, she said, "Senior, anal sex isn't cheating, right?"
