[ Hentai Manga ] Marine A Go Go 1

Based on the manga by Komiya Sanae and Nonomura Hideki. Dr. Narutaki, a genius who is attempting to preserve authentic Japanese males rather than the losers they have become, requires sperm from 100 specimens. The difficulty is that these 100 specimens will not offer it to him voluntarily, so he devises a strategy. Marin, a sexy girl from an all-female school, is put in a special outfit that turns into a man's desire and won't come off until she has collected all 100 semen samples. Southpole One, a sexaroid made by the doctor's assistant, is interfering by depleting and stealing the men's sperm first, turning the race into a race. "For the bright future of Japan, I shall take your semen!"
