I am a professor at a university. I often sit in the library, reading documents for my research. There is a female student who has been appearing recently. A beautiful and elegant girl, always quietly reading books. Sometimes our eyes meet. Probably because I haven't had much contact with women, I misunderstood. One day she started talking to me, it turns out she is Momo, a student in the class, being introverted and shy, I didn't pay much attention to students. For this reason, my class is often very boring. But Momo likes my lectures, looks forward to my next class, she also likes a writer similar to me, it seems there is some connection between us. I am also very impressed by Momo's shy expression. "If possible... I would be very happy to hear more from you, sir." It took me a while to realize that was her invitation. There was no reason to refuse, I took her home and talked about my favorite works. When it was late, I was going to take Momo to the train station, she suddenly confessed her feelings to me. When she said she wanted to "eat" me, I was confused for a moment, but because Momo kept advancing, I quickly synced with her. At this point, I realized that despite her innocent and pure appearance, her sexual tendencies were very "bold". I don't know when, but I have become her slave, following her wrong instructions, letting her have sex with me whenever she wants, doing whatever she says...
