Ore Wa, Shokushu Breeder ~kisei Shokushu De Naedoko-ka Suru Onna-tachi~

In Makai, there is a dungeon. In it, there are fighting competitions between horny men who are fighting to get a shot at the sinister succubus Masako Aoyuki. The plot and the fighting in the anime are amazing and so is the animation. There's lots of screwing and oral stuff after the fighting. You'll enjoy this.
