my girlfriend is a shy and pure literary girl. i was attracted to her modest and serious appearance, and i finally managed to start dating her. it was supposed to be such a fresh relationship where we hadn't even held hands yet. however, in my room, which i invited her to for the first time, she suddenly started masturbating while still in her uniform. she looked pure, but she was actually possessed by masturbation, an 'ona-kyou' (masturbation addict). at first, i could only be surprised. but before i knew it, i was also holding my crotch and showing each other. we sniffed each other, repeated simultaneous masturbation over the phone, and before we knew it, masturbation deepened our bond, even in the living room and tatami room. it was masturbation that connected us before love and before sex. now that i know the other side of my pure girlfriend, i can't go back to our original relationship. i am dominated by pleasure that cannot be stopped, and our days of closing the distance with insane mutual masturbation――. it might be a little abnormal, but it's a wonderful form of love that we have cultivated in our own way.
