My Clinical Trial Ended Up Being a Maso-Cum-Milking Hospital

I was a long-time shut-in.
The first job I decided to apply to was a clinical trial for a new vaccine.
Surely, this is an easy way for even someone like me to contribute to society!

But when I went to the hospital deep in the mountains,
all I found were naked men, leotard-clad women, and 24 hour surveillance.

This seems more like a cum-milking factory. They inject us with semen-enhancing formula,
and measure our dick data daily.
Sure, t's pleasurable at first, but as my cum-supply runs low,
it's like squeezing blood from a stone.
At this rate, my dick is gonna break, so I try to make my escape, but...
