Today, I'm Marina Saita, a 21-year-old born on May 9, 2002. My interest in sex started around third grade when I'd touch myself in the bath, feeling good without realizing it was masturbation. My first time was in junior high, with an 11-year-older guy who was very patient and gentle, so I felt it right away. I met my master, who shaped my current sexual preferences, when I was 16, and I was trained by him for three years. We did all sorts of things like candleplay, bondage, neck choking, and facial fucking, but since I didn't have much experience, I wasn't really aware of being trained as an M. I just got caught up in it without realizing it. I don't really like getting physical injuries or bleeding, but I love being mentally dominated. I'd get off just from my master's commands, even without being touched, just from his words and gaze. I became a body that could be turned on just by being stared at and hypnotized. I generally love insertional sex with multiple orgasms, but my master only inserted me every 3 to 4 times, so I think that made me more dependent on M-training play. In my case, I often reach multiple orgasms, and when that happens, I lose track of things. Even if I'm mentally orgasming, my body also spasms. It's different from the external stimulation in regular sex; the pleasure comes from within my body. When the intense pleasure lasts and I'm in a daze, I might cry, drool, or even have an accident. My lower body spasms particularly badly. Since I've become an M-trained body, even when I have a boyfriend, I ask him to step on me hard in his leather shoes or shock me with a taser.
