Breeding Femboys and what comes next

I'm seeking something long term, dark and slightly disturbing. I want to rp what happens when femboy(s) I'm willing to play one or multiple for different partners fall prey to those unruly beasts, and filthy monsters, and other dark fates.

I want to rp my character being impregnated and what comes from it the birth, the raising and managing of the kids. Perhaps he is trying to escape, accepted his new life, trying to keep his owner happy or even servicing his now adult children.

He could be the black bride of some demon a once virgin sacrifice now carrying the anti christ.

He could be trapped deep in a hive stuffed full of eggs forced to birth control standby from his tentacle, insectiod or xenomorph masters.

He could be a conquered prince who was o m ce proud now serves the lowly orc or werewolf conquerors as a communal toy. That or he is the prized egglayer of a conquering dragon.

Perhaps he was taken by aliens and insiminatedby a machine or taken to study the reproductive habits of his kind.

I have many ideas and few limits I just need the monster to do the deed.
