Weapon masturbation that every girl will have experience with. When I was innocent, I didn't have any sexual knowledge yet, and I realized that the corner of the desk that happened to hit my crotch felt good. If you move your hips slowly and rub the corners of your desk, you will be struck by a pleasant sensation that you have never experienced before. Since then, it seems that there are many girls who indulge in Kaku Ona by stealing their eyes. Once you taste it, no one can stop this urge!
