I forgot what it was called. But it was a foreigner who got stranded on a random island but then was deemed the queen of the island. He pretty much mated with everyone, then it turned to bestiality, then near the end his nipples and his urethra opened up so that men could use them as fuck holes.. it's just.. disturbing..
It's also on MyReadingManga but I'm just glad I forgot what it was called ( ̄∇ ̄")
