Its been 2 days since your repairs.
You have been wandering arkund the city for a purpose, the fine clothes given to you by the kindly creature who fixed you serving to draw undue attention from male - and some female - humans. A showy black skirt with decorative frills, tights and heels, making you look like you were cosplaying as an android from a game made decades ago.
You stumble upon an alley way where you hear voices, a man is attempting to force himself on a sex worker, thinking he's entitled to free sex for some reason. You dont care, but you were built for combat, it seems a good opportunity to test your repairs and upgrades. You charge down the alley rapidly, the man only registering your approach a second before you make contact. In less than a second you register new equipment and subroutines; your fuel tanks have been retrofitted for biological material. Before you can register the change consciously you sink your fangs into the man. He tries to fight you off but your metal body and machine strength is many times more than he can struggle against. Your new, tungsten fangs dig into him with ease as the sex worker flees in terror of you and him. You engage a pump to drain the blood from the man into the retrofitted sterile tank.
His struggling ceases and you drop him to the ground, blood dripping down your chin. You obfuscate your appearance and begin traveling using the alleys to get back to the creature who repaired you, to demand answers as to why it saw fit to alter your programming.
You enter its shack to find the creature unsconscious on the ground, paler than usual, coughing occasionally, small amounts of blood coming out. You recall that it needs blood to live and begin searching its food stores for blood for it to drink, finding its blood supplies depleted. It dawns on you that you inadvertantly drained an entire human's worth of blood, give or take a pint or 2. You have no means of feeding the blood to the creature except to reverse the pump in your throat to bring it back up to your mouth. You press your lips to the unconscious creature's mouth, parting its lips with your tongue and force feeding it the human blood. It jolts awake and swallows the blood eagerly, before running its fingers through your hair, mingling its organic tongue with your mechanical one. Its moaning as you feed it blood you stole, and a feeling is coming over your programming, it feels good for some reason.
It pulls away after having its fill, panting and regaining its color, it asks. "why did you come back...?"
"Why did you alter my programming, and give me the ability to drain, sterilize, and store blood?" You ask as a counter.
"Honestly...? To see if i could make a vampire combat doll. I didnt think id get to see it work in person though..." It responded, bedore continuing "i am sorry... I shouldnt have experimented with your being..."
You sit silently with it laying in your arms for a moment before responding "its alright, in fact... I think i know how to pay you back for repairing me."
"Oh?" It asks quizzically.
You kiss the creature again, before whispering "i will be your vampire doll, and i will hunt for you, as long as... You'll let me kiss you some more... Dolls will need you to fix them, after all..." Your words come out with a new emotion you werent accustomed to; you were nervous.
Its eyes went wide with surprise, before nodding silently.
"I can... Keep giving you more modifications to make it more efficient if... If you like..." It said, blushing.
