[ Hentai Sex Manga ] Marine A Go-Go Episode 1

Based on the manga by Komiya Sanae and Nonomura Hideki. Dr. Narutaki, a genius devoted to preserving authentic Japanese males as opposed to the losers they have become in the modern era, need sperm from 100 specimens. The issue is that these 100 specimens will not willingly give it to him, so he devises a scheme. He seduces Marin, a seductive girl from an all-girls school, and forces her to wear a special costume that converts her into a man's desire and will not come off until she collects all 100 semen samples. Southpole One, a sexaroid produced by the doctor's assistant, interferes by depleting and stealing the men's sperm first, effectively turning it into a race. "For the bright future of Japan, I shall take your semen!"
