IPZZ-823 | Having discovered that I possess a special type of semen with skin-beautifying effects, I've been isolated in a semen research lab as a test subject, and a beautiful, nymphomaniac doctor forces me to ejaculate multiple times a day into her face. 18 ejaculations, including some for my own selfish desires!! Sakura Momo

A man with an abnormally large sperm count whose erections won't subside.
After investigation, it's discovered that he has a unique constitution, occurring in only one in tens of thousands of people, and he's asked to be a research subject.
A female doctor is astonished by his extraordinary recovery ability, no matter how many times he ejaculates.

One day, while working, some sperm accidentally lands on the doctor's face,
and the skin where it landed becomes smooth and silky.
By chance, it's discovered that the sperm contains a large amount of ingredients that are excellent for beautifying the skin.
From that day on, the doctor is forced to have her sperm squeezed out of her through sperm collection and facial ejaculations, partly due to personal reasons...

A total of 18 massive facial ejaculations!
Sakura Momo happily accepts the sperm with a smile!
