"Tiny!? Premature ejaculation. Scumbag. Let's break up."

Tomoo Kagekura, a drab and poor college student attending a university in Tokyo, is shocked by his ex-girlfriend's words and develops ED. Tomoo, at the depths of despair, one day hears rumors of a suspicious "clinical trial part-time job."

It seems he will be staying at a hospital in the mountains for a month, conducting clinical trials for ED medication...

Tomoo participates in the part-time job, grasping at straws. Due to the efficacy of the investigational drug [O-1919], he becomes well-endowed & tireless, regaining his masculinity and confidence.

...However, the drug worked too well. At this rate, his junk will explode and he'll die!?

"The only way to calm down your erection is to have sex!" "What did you sayーーー!?"

The obedient nurse, Touwa Usakami, who has just tasted the flavor of men. The attending physician, Kaori Usakami, who adores Tomoo like a guinea pig. His ex-girlfriend, Himeno Tanba, with whom he has a chance reunion. Meg, a part-time coworker who loves sex and cosplay.

A steamy and erotic clinical trial part-time job with these four women now begins...
