Masturbation with a sharp object, something every girl likely has experienced. Back when they were innocent and didn't know much about sex, they might accidentally discover the pleasurable feeling of a desk corner touching their crotch. Slowly moving their hips, rubbing the corner against their genitals, they're overwhelmed by a sensation unlike anything they've felt before. Apparently, many girls secretly indulge in this kind of masturbation after that first experience. Once they've tasted it, this urge becomes unstoppable! *Please note that the recorded content may vary depending on the distribution method.
