Nitta helped Natsuki, who had never orgasmed before, with her masturbation, but only he ended up orgasming, and lunchtime was over. Nitta was tormented by the memory of what had just happened. Natsuki appeared calm, but she reached her hand under the desk and touched Nitta’s crotch. Natsuki lifted her skirt as if to continue from where they left off during lunchtime, inviting him. Nitta desperately wanted to make Natsuki orgasm, and despite being in class, he reached for her crotch. They continued to play with each other’s genitals without being noticed, but Natsuki still couldn’t orgasm. Finally unable to bear it any longer, Natsuki grabbed Nitta’s hand and hurried out of the classroom.
