* This work is a compilation of videos posted in the SM magazine "Mania Club". [Message from the poster, Katsuya (pseudonym)] It's an embarrassing story, but I've been looking at my sister as a woman since I first remembered it. I have never masturbated thinking of my sister once or twice. It was my dream to be connected with my sister. My sister's marriage made that dream forever unfulfilled. When I gave up thinking that way, I was surprised to find that my sister asked me. The comfort of my sister's female genitals was the best of any Onaho I've ever used. But that first experience was far from my ideal. In my delusion, my sister was mine and my property. But in my first sex, I was at the mercy of my sister. That's why I decided. Trying to have sex with my sister again. I wanted to train my sister in my ideal way. [Scene 1] I relived the "playing doctor" that I enjoyed when I was little with my sister. I will clean up my sister who leaked in the diaper. And every corner of the body of the younger sister who changed into gym clothes is inspected. When I palpated the inside of Oma Co ○ with my finger, I estrus with a hailful voice, so after giving plenty of blowjob service, I injected a meat stick from the back. [Scene 2] Although she is usually a strong sister, it has become clear that her true face is a masochist who desires harsh blame. When I ordered him to come to the meeting place with the vibrator on, my sister kept her promise and appeared with a cheerful face. On this day, I prepared various props to bully my sister. I restrained him on the wall, hit him with a paddle, and teased his pubic area with a nasty toy. I was so excited that I sucked my penis, and finally I straddled my sister's face and shot it in my mouth and gave me sperm ... [Scene 3] In order to educate a cheeky younger sister, I restrained her in the back and made her give a blow job. I can't use my hands and serve only by mouth, so I can't keep up with my sister's pace. After that, I kept committing my sister to my heart's content in a closed room with only two people and taught me the taste of my penis.
