Maki greets him with a smile, but Kazuya, who has a strong libido, suddenly consults her to teach her how to put on a condom instead of studying. Maki, who is originally weak to push, can't refuse clearly, and puts it on his erection as she is told. Kazuya, who was excited about his first rubber, couldn't stand it. Maki desperately persuades her, but her mind and body, which are vulnerable to pushing, are defeated by his forcible caress and young and strong meat stick.
