Sugimori Yoshiyuki was seriously injured with fractures in both hands and had to spend time in the hospital. One night, his dick was affected by a mysterious anomaly! His dick became so stiff that it ached, his testicles swelled up, and he experienced intense ejaculation symptoms and a spectacular desire to jack off.

Yoshiyuki's realizes that he's in the worst case scenario; he can't cum even if he wanted to. In this state of agony, the nurse in charge Tsutsumi Kanon, offers him a helping hand, or rather, a pair of tits.

She smiled like an angel, and then smothered his cock. Now he's in between her ample tits that are bobbing up and down, while she wraps her wet lips on his cock. These vulgar sounds as she sucked did not match her innocent appearance, and she knew just what to do to make a man feel good.

The next day, Yoshiyuki is told a startling revelation by his doctor, Sanetou Shiori.

"Due to symptoms of excessive erections and abnormal semen production, your penis and testicles may burst if the condition isn't dealt with. But rest assured, the nurses I have chosen will take good care of you, and the problem will be solved."

The three assigned to Yoshiyuki are Tsutsumi Kanon, who is soft, innocent, and motherly, Nanase Ana, who is a cute seductive gal, and Amasawa Sayaka, who exudes a mature and seductive charm.

Thus, Yoshiyuki is nursed by three experienced and sexually active bitch nurses.
