I first learned about Monaka at SM Night in December 2022. She asked her agency manager to show her because she was very interested in SM. After the performance, she was introduced to the agency and said that she was interested in SM and wanted to appear at SM Night Itsuka. Around spring 2023, Monaka left her exclusive contract with a certain manufacturer and started working on projects on her own, so I asked for an interview. When she was 10 years old and in the fourth grade of elementary school, she asked her mother to let her learn to dance, and in exchange she was told to become an idol, and from then on she began working as a local underground idol. From the age of 10 to 17, Monaka worked hard at her idol activities! In the dressing room, she was always alone in the corner of the room and never spoke to anyone. Apparently, the members called her gloomy. When she went on stage and put on the idol mask, Monaka danced and sang with a bright and energetic energy! In this shoot, I decided on the theme of stripping off the idol mask that had taken root in Monaka during her first hardcore SM experience. First, in the bondage training with rope master Nuegami, she began tying up in a pink outfit similar to the one she wore when she was an underground idol. Monaka has a lolita face, but has very large, beautiful breasts. Her reaction when tied up with rope was very erotic. When wooden clothespins were attached to her tongue and nipples and pulled, she let out an erotic voice and immediately began drooling. When she was lifted into the air for the first time and her beautiful breasts and panty-clad crotch were hit repeatedly and violently with a rose whip, she screamed and lost consciousness in the air!! Just seeing her reaction and erotic potential, I was convinced that Monaka Sengoku is suited for hardcore SM!!
