This video is an amateur video sent to an SM magazine. *All names are the names of the posters. [From the male poster] Aika was a beautiful girl who was well-known at school. She was 155 cm tall, boyish, active, and outwardly a pure girl who was liked by everyone. She was a mismatched girl, a perverted middle-aged teacher who went to SM clubs to satisfy her sexual desires, so she should not have been paid any attention to me. However, now I put a vibrator in Aika and take her for a walk with a collar on, which is the height of perversion. When passersby look suspiciously at us, who are so far apart in age, she clings to my arm and appeals that we are in a consensual relationship. [From Aika] I am a second-year university student. My master is my teacher from my high school days. At that time, I boldly confessed to him, but there was nothing between teacher and student. After that, I passed the entrance exam for the school I wanted to go to, and on our graduation date, I became the teacher's. We are in a long distance relationship now, but (1) we contact each other at the same time every day, (2) we shave, (3) we take the pill so we can cum inside whenever we want, (4) we masturbate on the phone with the teacher every night, and on days when we can't call, we don't masturbate, and (5) on the days when we don't masturbate, we take sexy selfies and send them to him, so I feel like he has me all to himself, and I'm happy. This time, the teacher asked me to "declare that he now owns me," so I posted it to commemorate my 20th birthday. My dream is to one day marry the teacher and have him keep me for the rest of my life.
