In, Monster Girl Breeder, the protagonist is preparing for a gamming session playing the latest erotic fantasy game when he finds himself being whisked away to a fantasy world. The most surprising thing is, he wakes up surrounded by horny monster girls who need him to repopulate their isolated village. Yes, that means he's going to have to fuck all of these monster girls so they can get knocked up and flood their village with brand new little monsters. It's a tough job, but the protagonist in this game certainly can if anyone can do it.
