[First collaboration between the genius of modern erotic fantasy F4U! ] The teacher, who doesn't know the ejaculation control system, cares about Momonuma, a girl with glasses who is shaking in the classroom and ends up pairing up. The teacher is confused by the sudden onset of ejaculation control, but accepts it for the sake of his students. However, despite her plain appearance, she was a super lewd and incredibly slutty slut...! I'm always being overtaken so much that I can't help but feel stupid in my classroom, in the library, or at home! "If you can hold it in, can I insert it?" Every day by a girl with super-sexual sex squeezes into her chest!
