I keep returning to this kink and looking at the posts of horny trans boys who get off to the same thing.

Some of my favorite fantasies to explore are ones where the sub is kept in a constant state of domestic servitude. Either they could have a normal life outside of the house - only to be reduced to a slave whenever they’re at home OR they could be made to be a 24/7 servant, rarely or never leaving the house and always waiting to be used again.

There’s lots of forms this fantasy could take: keeping someone as a pet, a maid/house slave, etc.

My personal favorite version is the idea of taking a trans boy and allowing them to present as male in public, only to treat them as a submissive wife in private.
