"I'll guide you... Sorry, I climaxed too much!!" He thought he was going to teach a nearby college student about sex... but because he hadn't had sex in so long, he was brought to orgasm by a young penis. His uterus, twisting and constricting, gripped the riding position and couldn't stop. His unsatisfied wife, Kitano Mina, HMN-574, was filled with desire.

One day, a married woman discovered that her college neighbor, Hajime, harbored feelings for her. During her husband's time away on a foreign mission, she was sexually frustrated… So she began to seduce Hajime and bring him home. Of course, she was dominant… However, the long-awaited sex and Hajime's unexpectedly firm penis overwhelmed her will, causing her to climax multiple times. "Ah, um… I'm so sorry…" she cried, unable to control herself. Even after being penetrated multiple times, she still used the apologetic riding position with vaginal thrusts. "Young man… young man…" she climaxed nine times, feeling ashamed before the young man.
