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 nearby recently. A beautiful and elegant girl who always reads quietly. Sometimes our eyes meet. Probably because I haven't had much contact with women, I misunderstood. One day she came to talk 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. It's also for this reason that my class is often 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 kind of connection between us. I am also very impressed by Momo's shy expression. "If possible... I would be very happy to hear more stories from you, sir." It took me a moment 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 when she suddenly confessed her feelings for me. When she said she wanted to "eat" me, I was confused for a while, but because Momo kept advancing, I quickly synced with her. It was only then that I realized, despite her innocent and pure appearance, her sexual tendencies were very "bold." I don't know since when, but I have become her slave, obeying her wrong commands, letting her have sex whenever she wants, doing whatever she says...
