you should add a sucubus on the females side and give her stealth pounce and breed
she could breed the monsters to death and the reason she dont get picked up is she has a aura
the other girls could also learn it from her and each has their own ability to knock guys down some might use drugs others poison others a aura like the sucubus
another type could be stunning looks this basicly stops anyone monsters from interfereing while a girl with stunning looks is breeding
why:
simple ive always loved counter play another idea could be a strong girl like a amazon who can drag the monsters into bushes 1 block rooms and other safeish zones to breed them into a broken state they cant recover from
another idea could be breeders cause mental damage while breedees cause stamina damage
example one girl is finishing off a mate and another is standing there the monster who activated the assault breaks the 1 girl mentally but drops her because he has gotten hit the monster would have low stamina and would gain perma stamina damage if he gets breeded this would make him extremly weak to a point where the girl would have a easy win against him
the idea is to warn off players from abusing it around other monsters
