It all started back when I posted on a sugarbaby dating site. I was bored of guys my age, all talk and bragging, but not really that great in bed. I wanted an older, more experienced man. Someone dominant. Someone who knows what he wants. Someone who knows how to get what he wants from a girl. I wrote all that on my profile, and you answered. You're all I was looking for, and on top of it all, you're pretty great looking. You worked hard to get where you are, and now you can afford a life of leisure, able to buy any experience or thing you want.

I quickly realized that to you, I am an experience you buy, a thing you buy. My job is to look pretty when you take me out on dates. Just looking at us, everyone knows what's up, but I enjoy it, and you don't mind. For you, I exist to look pretty, and of course for you to fuck whenever you feel the need. And our sex is amazing, everything I dreamed of.

After a short while you started to refer to me as "your doll" almost exclusively. And it made my stomach flutter each time you did. Of course you noticed, and after you suggested it, we hashed out a deal: I will become your real life fuckdoll. You will have full power and control over me, in every aspect that is possible. You will set aside a room in your mansion for me to live in, and I will do everything you tell me to, without hesitation or protest. Yesterday evening we signed a contract, set out by your lawyers, stipulating that we would keep this arrangement for at least five years, starting today, and with the option to continue on after that if we agree. You told me to be ready to get picked up for my new life bright and early today.

You left me with specific instruction: Be ready to be picked up by 8 am, wearing only a pair of high heels, and a long coat. With your help, I have already put all other things I own in storage, and terminated my lease, I won't be needing anything except what you provide me for the next five years at least. Then your limo stops next to me. Your driver opens the door for me, and I get in to start my new life, unsure what to expect, but my heart fluttering in excitement.

"Good morning, doll. I have a surprise for you." You greet me businesslike, and then ignore me for the rest of the drive. We drive through the city for a while, and stop next to what could be a tech startup, except there's no signage out front: A modern, clean office and lab building. Clearly someone is expecting us, because we are greeted by two burly men. They wordlessly lead us through a series of nondescript hallways. The building seems empty, the sound of my heels clicking on the floor echoing. I'm starting to feel a little anxious, when the men open a door into one of the laboratories and lead us inside.

The laboratory is clean, white, and futuristic, with glass-like softly glowing walls and ceilings. In the middle of the room is a workstation, with a couple displays and keyboards on it, next to a doctors chair with stirrups and armrests. On second glance, I notice that the chair is fitted with restraints for every body part of the person sitting in it. I'm about to ask you what's going on, when the man sitting at the workstation turns around and greets you: "Ah, this is the specimen, then?" he says, gesturing to me. "All right, let's begin!" he continues, but you interrupt him by lifting a hand and turning towards me:

"You have a choice to make here." you explain to me. "I'm planning to have you implanted with a neurological implant. It allows controlling virtually all your bodily functions, and your behavior, through a phone app, or verbal commands. You will for all intents and purposes become a living fuck doll. There's no risk associated with the implant itself: It's not a prototype, it's proven technology, although not widely advertised."

"Your choice is this: If you don't accept the implant, nothing will happen. You will go back to your life as it was before, no hard feelings. But if you choose the implant, know that the next choice you will be allowed to make on your own is whether or not you want to continue our arrangement in five years time. You will be my fuck doll for at least that long, and I will decide everything about you. After five years, I'll deactivate the implant if you want me to. If you want to go ahead, just drop your coat, sit on the chair, and put your feet into the stirrups."

I'm standing dumbfounded, at some point my mouth must have dropped open. I can't believe what you're telling me. My heart is hammering, and my thoughts are racing through my head. But after a few moments, a decision crystallizes in me: This is what I want. I want to be your fuck doll. "I'll... I'll do it." I say, drop my coat, and sit down in the chair. "Thank you!" you say while I put my feet in the stirrups. Where you were distracted and businesslike before, you seem relieved and excited now.

Immediately, the two burly men start applying the restraints fixed to the chair: They first strap down my wrists and ankles, then my knees and elbows. A broad restraint fixes my waist to the chair, another one goes across my chest. Lastly, one of them says "open wide", holding out a penis gag on a last restraint. Obediently I open my mouth, and he pushes the gag inside, using it to strap my head down to the chairs headrest. In just a few moments they tie me down to the chair, and I'm now immobilized, I can only wriggle my arms and feet a little bit, the rest of my body is held in place by sturdy straps. My heart is hammering, and I feel vulnerable and helpless, exposed and tied up in front of you and the three strangers.

The lab technician picks up something from his desk. I can see him from the corner of my eyes, moving to stand behind my back. The headrest has a circular opening, and the technician presses something against the base of my neck, and the next thing I feel is a sharp stab of pain and an incredibly loud thunk. "Mmmph!" I cry out into the gag. I can feel something cold and metallic shoot into me, nestling next to the base of my head, and what feels like tendrils crawling out from it, and I feel my body shuddering all over, and black out...

When I come to, I feel that I'm no longer strapped to the chair, but I can't move. "Ah, the implant finished mapping and mating with your doll. We can go ahead with testing and setup now." He picks up a tablet from his desk and stands up. "I know you already know this from the sales demonstration you witnessed, but the doll has three basic modes. Right now, it's in doll mode, where it can be posed, will stay in that pose, and will be able to follow very simple verbal commands." He takes my arm and lifts it up into the air. I feel it move easily and freeze in place, without being able to move it myself. "Move your arm back to the armrest." the technician commands, and immediately I do so- moving the arm, but not feeling myself decide to do so. "Then, of course, is the autonomous mode..." the technician taps the tablet, and I feel myself unfreeze. I lift my head wide eyed, touching my face with my hands: "Hooly shit, that's such a mindfuck..." But that's all I manage to do, before the technician taps a button again, and I go limp and slump back onto the chair. "... Aaaand of course we have the off mode."

"Next, we have arousal control." He starts showing you on the tablet. "Here, you can see your dolls arousal levels. You can set a minimum and maximum level..." I can feel a wave of pleasure first run all over me, then disappear just as suddenly. "... and you can, of course, also control its orgasms. You can disable them completely, have it trigger an orgasm each time someone cums into one of its three holes, have it orgasm normally once its arousal levels are high enough, or trigger an orgasm manually. And for the last thing to go through here, we upgraded your doll to have full fertility control for free- it's our latest feature. Similar to arousal control, you can set your dolls fertility from completely infertile, all the way to conception being virtually guaranteed."

The technician hands you the tablet: "This remote is, of course, included in your purchase. I suggest pairing your own personal cell phone to the doll for convenience as well, and then all that's left is for you to complete the customization wizard, and pack up your doll. By now, our technicians should be done with installations at your mansion."

The technician stands back, and you tap the tablet and give me an order: "Stand up." You must have put me back into doll mode, because I get up, and stand, and then remain standing frozen, my feet shoulder width apart, my hands at my side. You walk behind me, and I feel you touch the back of my head with your phone. Immediately I speak out: "Pairing successful." You walk back out in front of me: "This is awesome!" You say, looking me over, and then tapping on your phone. "Now, your name... your name will be Doll." In what feels like a flash of white light, I forget my old name, and know that I'm Doll. "And default settings are... hm... 50% minimum arousal, only orgasm by creampie, and infertile."

Then, you step back and gesture to the side: "Doll, pack yourself." I turn to where you're pointing, and see what looks like a stage box, a large crate with its sides flipped open. There's what looks like a Sybian mounted on the base, with two dildos mounted on it, and a third dildo at mouth height, held by a stand. I feel like a preprogrammed sequence must be running: Without being able to control myself, I walk towards the crate, and straddle the base, without hesitation inserting the two dildos into my pussy and ass. Then my body leans forward, my mouth opens and I slide the third dildo into my mouth, before freezing into position again. With the help of the technician, you close up the sides, pressing the padded, form fitting foam padding against my body. I feel the base that I'm straddling whir to life: Something wet and warm is pumped into my pussy and ass repeatedly, and then pumped out again, while the dildo in my mouth starts to pump a thick syrup into the back of my throat, forcing me to swallow it. I realize that it's cleaning and feeding me, while I feel the crate I'm now in jostle and move, as I'm shipped out to somewhere...
