Hello everyone, my name is Hosoda Keiko. I was born on May 9, 2002, and I'm currently 21 years old. My sexual desires first began awakening when I was in third grade. While taking a bath, I unconsciously touched my crotch and found the sensation pleasurable, though I didn't yet understand it was masturbation. My first sexual experience happened in middle school with someone 11 years older than me. He was very gentle and took his time, so I didn't feel any pain and quickly began experiencing pleasure. Later, at age 16, I met my current Master, who shaped my current sexual preferences. Through three years of training, I experienced various acts including candle play, bondage, choking, belly punches, and brain orgasms. At the time, I didn't consciously identify with masochistic training—I simply fell into it naturally. I'm not particularly fond of physical injuries on my body, but I absolutely love psychological domination, often reaching orgasm just from my Master's words or gaze. I've even become someone who can climax simply by being stared at while receiving a countdown. My favorite is G-spot orgasm through intercourse, but since my Master only allowed penetration once every three or four times, I may have grown increasingly dependent on masochistic training. I often experience continuous orgasms, during which my consciousness becomes hazy, my body convulses, and an internal pleasure unlike normal sex overwhelms me. The climax lasts a long time, sometimes making me cry, drool, or even involuntarily urinate as I lose awareness. I especially tend to experience strong convulsions in my lower body. Since becoming trained through masochistic play, even when I have a boyfriend, I find myself actively asking to be stepped on with leather shoes or stimulated with a stun gun.
