If I volunteer to join a sperm bank, I'll be considered an exceptional donor, and the unpopular man, whose semen is forcibly collected by female doctors and nurses whose eyes change, until he's completely depleted, will be called DOKS-668.

An unpopular, mediocre man volunteers to join a sperm bank and is immediately recognized as a once-in-a-decade exceptional donor!? From female doctors who want to study the data to busty nurses aiming for temporary bonuses, his semen is continuously collected until his testicles are empty... a dreamlike busty harem clinic!!
