*This work is a collection of videos posted in the SM magazine "Mania Club". - [Message from the author, Katsuya (pseudonym)] It's an embarrassing story, but ever since I can remember, I've seen her sister as a woman. - I masturbated thinking about her sister more than once or twice. - It was my dream to marry her sister. - Her sister's marriage made that dream impossible forever. - I thought so and gave up, but to my surprise, her sister asked for me. - My sister's vagina feels better than any masturbator I've ever used. - But that first experience was far from my ideal. - In my delusions, she was mine, my property. - But the first time I had sex, I was at the mercy of my sister. - So I made up my mind. - Trying to have sex with my sister again. - I thought I would 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 after my sister who leaked in her diaper. - And inspect every corner of my sister's body who changed into gym clothes. - When I palpated the inside of my pussy with my fingers, I raised my voice and got into heat, so after giving me a lot of blowjob service, I gave him an injection of a meat stick from the back. - [Scene 2] She is usually a strong sister, but I have come to understand that her real face is a masochistic temperament that wants severe punishment. - When I ordered her to come to the meeting place with the vibrator in it, her sister kept her promise and appeared with a cheerful face. - On this day, I have prepared various props for her to bully her sister. - She was strapped to the wall and paddled against her body and nasty toys teased her twat. - Unexpectedly, I got so excited that I sucked her penis, and in the end, I straddled her sister's face and shot it in my mouth, and made her drink her sperm. - [Scene 3] In order to educate my cheeky little sister, I bound her hands behind her and made her give me a blowjob. - I can't use my hands and serve only with my mouth, so it won't be my sister's usual pace. - After that, in a closed room with just the two of us, I continued to rape my sister to my heart's content, teaching her the taste of my penis.
