Summary

The following content is intended for mature audiences and may contain sexual themes, gore, violence and/or strong language. Discretion is advised.

Jegal Hyeon, the youngest team leader at a design firm, has lived for 32 years with a blessed(?) personality that has irritated everyone around him.

Then, one day, he is suddenly abducted by a mysterious UFO!

Waking up in an unfamiliar place, Jegal Hyeon is subjected to a 'Development' experiment under the observation of the spaceship's Captain, Callisto, and the head researcher...

"Just stimulating my XXX will NOT make me scream like a lust-crazed XXX! What do you think men are?"

"I... I'm feeling pleasure from the back?"

"I'm a man!"

The beginning of the project ? The Feminine Degradation Experiment!
