What you hadn't expected to see what a giant mansion. More so that no one around you seemed to even look at it. How had you NOT seen this thing before?! And, it was covered in dust, cobwebs, and look faded in several spots, and the garden was unkept. You were surprised when the front gate was not locked.
You knew you were likely too get arrested for trespassing or something, but this giant old house... well, seemed to call to you. It sat so large and empty, it felt like a shame to be left so hollow. Or maybe you were just being curious and hoping that it worked out better for you than it did for the cake.
There was a grand father clock unwound in the foyer. But... there was a folded message on a table. And unlike everything else, it wasn't covered in dust. Feeling like a sucker but unable to resist, you opened it.
"Hello, by opening and reading this message, you are now bound to this house as it is bound to you. You will know this to be true. You and this house are now join at the hip. This house's survival is now your survival. This is your fate. You are both master and hostage of this place.
'Anyone who enters this place after you is now yours to mold the mind, body and soul of as you see fit by right. However, the foundation of their new form is set by the very fabric of this place itself. However, if you'd find these kinds servants unappealing, you wouldn't have found this place. You will need many servants to sustain this place and you. They will not be mindless automatons, but they will love you unconditionally, and will prioritize your wants and needs, and be underlying loyal and obedient.
"However... if you should ever try to do anything naughty with them, or intentionally and willingly allow anything naught to happen to them... you will die screaming, and never stop screaming.
"They shall be immortal and serve you eternally. But in return for their obedience and servitude, you are to ensure their own happiness as well."
"Hey! Who are you? Are you a thief or something? I'm gonna call the cops!"
You turn around to see an angry woman looking at you... with a thought you reach out and touch her with the power of the house.
She shrinks down.. becoming about half the height she'd been before, but her figure still very clearly that of a grown woman if rather squat. Her skin turns into brown plush fur. Her eyes become plastic and golden. A black and white maid uniform appears on her body that may or may not be sown into her form, and a baby doll diaper appeared between her legs that you knew instinctively was just for show. Her human ears vanished to be replaced by cat ears. A tail poked out of her dress and her feet and hands became paws (with a thumb for the paws), while her face pushed into a muzzle. Her body and head became full of fluff.
The new pluhsie cat girl looked up at you and smiled, and curtsied. "Master, name me, command me, give me my purpose. I shall serve and obey!" The first of many.
