MAZO-020 Deviation value 75 Student Council member 'I'm a good girl in front of my parents...' Releasing stress with an extremely narrow hole, the masochistic young lady orgasms instantly, eyes rolling back to the limit

Student council member (1●). A top-tier beautiful girl who exudes clarity. She retired from the band in spring. Anticipating recommended exams, she also joined the student council. Her behavior is exemplary, and teachers praise her; she strives to meet her parents' expectations. Despite this, she didn't succumb to pressure and continued playing the role of a good girl. However, even such an excellent student has another side. At home, on the train during commutes, in the classroom... Even when mindful of others' eyes and appearing well-behaved, it seems different once in bed. She started using SNS to pass the time before classes begin. The number of likes skyrocketed whenever she posted selfies, which felt strangely good. Direct messages from strangers increased, and school complaints naturally spilled out. This has become more common with the spread of smartphones. From there, she ended up with a pervert... Though confused, her first sexual experience made her instantly hooked. It felt a hundred times better than masturbating in the bathroom. Her developing breasts were forcefully sucked by unfamiliar devices that restrained her body. Slowly oozing out thick love juices. Even her pubic hair was tied up... Her bean-sized nipples were stimulated, growing larger, and today she's erect (laughs)! Her small butt was held with both hands, and a raw penis pistoned into her from behind over and over. Treated like a fleshlight, even her underage anus twitched. Defeated by the adult's stamina, she reached climax and 'Ah... ah... it feels so goooood!!!' Her vaginal pressure naturally increased to squeeze out sperm. At this age, she was pounded into being a female, reaching orgasm like that. Of course, they'll meet again next time.
