This is an amateur video submitted to an SM magazine, and the names of those involved are pseudonyms. According to the male submitter, a girl named Aika is known as a beautiful girl on campus. She is 155cm tall, has a boyish and lively personality, and has a pure appearance that everyone likes. It seems unlikely that she would be in a relationship with a perverted middle-aged teacher like me, who is much older. However, I've reached the point where I've inserted a vibrator in her and made her wear a collar, and we lead an unusual daily life where she walks around with me. As passersby give us suspicious looks, she clings to my arm and shows that she's with me consensually, like in an unhealthy love drama. According to Aika, I'm her former teacher and current master. When I was her student, she confessed to me, but I turned her down because of our teacher-student relationship. After she got into her desired university, we started dating on a graduation trip, and now we're in a long-distance relationship with strict daily rules. For example, she has to contact me at a set time every day, shave her body hair, take birth control pills so I can have creampie sex with her, have phone sex every night or not masturbate that day, and if she can't masturbate, she has to take erotic selfies and send them to me. She follows my demands faithfully. I told her to declare that she's my property, so she sent this video for her 20th birthday. Her dream is to marry me one day and live as my possession forever. Despite the unreasonable relationship, she enjoys being dominated by me and depends on me.
