It only seems fair.

I gulped. “I guess that’s a fair request. Just don’t go too crazy with it, okay? I promise I won’t either.”

“Sure, I’ll respect your boundaries. But if you mean you won’t touch me when you say you won’t go too crazy with it, then I’m calling it off.” Jade got close to me again. “If you turn me into a sex doll, I want to be used for my intended purpose.”

My pants became tight. “So, uh, I guess there isn’t a bed in here, but do you have some soft surface to uh… play on?”

“Oh, we have inflatable mattresses somewhere! Let me get that real quick!” She ran toward another aisle and came back with a package of folded plastic and a small battery powered pump. We spread the mattress behind the counter and set it to slowly inflate. “So now for your choice of toy for the day: I guess if we’re doing this, we might as well do it with one of the expensive realistic ones, right? Or do you get off to seeing me reduced to a bunch of cheap simple plastic?”

“No, realistic is definitely better. I think we need to unbox the doll though if we want to copy it with the Alterscope.”

“The Alterscope? Is that the name of this thing? Well, then you better be able to pay for the doll. No customer in their right mind will buy a box with a broken seal on it, who knows where that might have been.”

I looked at the three-digit sum on the price sticker, and got the required amount out of my wallet. Thank the Alterscope for letting me avoid financial troubles. Jade handed me the box to open while she went to the register to put away the cash.

The doll was surprisingly heavy, featuring arms but not legs, and its ‘skin’ had a rubbery feel to it. It was soft and yielding to the touch, but there was an inner structure preventing me from pinching completely through any body part. Its exaggerated boobs were fitted with a little valve, presumably to be inflated even further. The face occupied that really uncomfortable part of the realism spectrum, with a hole hiding behind painted silicone lips and two realistically painted blue eyes staring at me unmovingly. A wig of high-quality blonde hair decorated the top of its head.

“You done admiring her beauty? Don’t worry, she’s self-lubricating and the reservoirs come pre-filled out of the box. Also I’m sure you noticed the little valve between her boobs, that’s compatible with the pump we used on the mattress, if you want. I’m sure she won’t mind.” She winked at me, then plonked herself down on the mattress. “I’m ready when you are. It’s about two PM now, my shift goes until six. We can leave the shop closed, usually there’s fuck all customers on an afternoon like that. Maybe turn me back around four, so I can turn it around on you?”

I nodded awkwardly, not looking forward to becoming subject to the Alterscope’s magic myself. “Sure, sounds good to me.”

“So then, show me how that blue lens on your ‘Alterscope’ works. I don’t need to be naked for this, do I?”

“Not as far as I know, no”, I assured her. I armed the Alterscope with the emerald lens and copied the doll, then I carefully slid the ruby and, for the first time, the sapphire lens into place and took aim at Jade.

“So, you sure you got everything set up corrhhhhhh” Her question was interrupted by a quiet hiss coming out of the new doll’s mouth valve. Her spiky blue hair had a distinctly artificial look to it now, and her grey eyes gave the impression of being painted on. She was still wearing her tattered clothing, although the cotton of her shirt had a definite plasticky sheen to it now.

I reached out to touch her cheek, marveling at how different her skin felt to the silicone rubber of the original doll. “So you’re still in there and you can feel this, can you?” A sudden feeling of guilt and concern came over me. What if she was paralyzed in there, desperately trying to move or speak? How could I live with myself if I woke her up in two hours’ time, only to find her traumatized?

I got back up and took the Alterscope from the counter, switching the lenses out for the amethyst one.

After a quick press of the button, I heard a deep inhale coming from Jade, quickly dissolving into rapid panting. “Getting cold feet, huh? gasp Yes I could feel you gasp touching me. gasp It’s amazing!” She took another deep breath. “Now turn me back into a doll and have your way with me, before I change my mind and turn you into a dildo to get myself off!”

Thus motivated, I quickly did as she commanded. I lowered myself to kneel over her, then leaned down and carefully tasted her lips. They felt warm and soft and real, but with a tinge of artificial cherry flavor that had to have come from the original doll. Exploring deeper with my tongue, I discovered a smooth tunnel that was probably more designed to accommodate my cock than to be kissed. Regardless, it oozed more of that sweet cherry flavor, which probably doubled as lubricant for when the hole had to accept things other than tongues.

I got back up onto my knees and struggled to get her shirt down over her shoulders, making her boobs wobble a bit when I slid it down her torso. Due to the doll being legless, I had no problem pulling it off of her completely, rendering her naked and exposing her artificial pussy. Apparently, whatever underwear she might have been wearing had disappeared in the transformation as well.

Her tits were the next thing to get a haptic appraisal from me. Groping them felt weird, not as stiff as pure silicon would normally feel, but they were still much perkier than natural breasts of that size had any right to be. They weren’t as big as those on the template doll, but still more than the large handful Jade had hidden under her shirt when she had been a breathing human. Remembering that there actually was a conscious human being under the artificial shell, I switched from exploratory gropes to loving caresses, teasing all around the spherical mounds, then finally bending down to kiss an erect nipple. I was rewarded with the same sweet artificial cherry flavor I had already tasted on her lips, and suckled on the nub a bit before moving on.

With my erection slowly but surely becoming too much to handle, I decided to free it from my pants and finally make use of the Jade doll’s primary function. Having already discovered the hidden depths beneath her lips, I was eager to find out how it felt to stick my dick in there. I put myself on top of her roughly in a sixty-nine position, and aimed myself at her lips. They parted surprisingly easily, bathing my penis in a feeling I hadn’t known before I had tested the Amber onahole the day before. The opening was warm and soft, and its walls seemed to subtly tighten and loosen with every one of my movements, caressing my penis along its whole length.

Eager to reciprocate the pleasure I was receiving, I bent down to taste her pussy as well. It was modeled in a surprising amount of detail for a sex doll, featuring outer and inner lips and even a clitoris. All of it was bathed in the same cherry-flavored lube as her mouth and nipples, and a few licks across her lower lips only brought more of it out. After a short while of licking those lips and simultaneously thrusting erratically into her mouth (it’s harder than it sounds maintaining a rhythm and also keeping your mouth on target when your partner is a completely motionless doll and you have to make every adjustment for yourself), my tongue found its way toward her clit.

In response, I felt her mouth-hole suddenly tighten around my cock, sending me over the edge and causing me to fill her mouth with cum. When my first spurt hit, some mechanism also triggered a squirt of lube to shoot out of her pussy and onto the inflatable mattress.

Coming down from my high, I rolled off of her and sat up. Her form still lay there motionless, staring up at the ceiling beside me, presenting her mouth, tits and pussy to anyone who dared take them. Her mouth seemed to feature the same ‘special cum catcher design’ as the onahole she had sold me yesterday, as there wasn’t a drop visible around it despite my messy climax just a minute ago.

I also noticed the valve between her boobs again, designed to accept the plastic tube from the pump right next to us. It took only a few moments to connect the tubes up correctly, and soon the pump was humming and slowly filling up her breasts.

Putting my hands on them again, it was easy to feel the pressure within, pushing apart the thick elastic silicone and spreading the fingers I laid on her. The texture of warm skin felt even more incongruous now that the spheres were being pumped up like two balloons.

As they slowly grew, I couldn’t help but wonder what my dick would feel like between them. Sticking it in though, it quickly got lost in the cleavage, and there wasn’t enough lubrication to make it feel as good as the holes on the doll that were specifically designed for this kind of pleasure. Still, with how Jade had reacted to being turned back earlier, I wondered how this would feel for her right now. I could only imagine the sensations to be extraordinarily pleasurable.

When the two tit-balloons reached the size of the rest of her torso, my dick decided that enough was enough and it was time for a second round of fucking. I turned off the pump and settled into a more normal sex position, if you can call missionary with the man squeezed in between two giant flesh balloons ‘normal’.

I had to prop myself with my hands against those giant spheres to get any rhythm going at all, but when I finally did, the bounce and wobble in her tits was spectacular. It, combined with the finely tuned ministrations of her pussy, was enough to bring me to a second climax in no time at all, depositing another round of seed inside her ‘special cum catching’ depths.

I decided that despite how hot it had looked to inflate them, the exaggerated size of her breasts was a bit over the top, and disconnected the tube from the pump. Squeezing the valve to let out some air, I rested my tired body against them to **** it out faster. I remained there for a minute until they reached a size that could conceivably exist on a human, then I closed the valve and popped it in again, leaving the Jade-doll with still much larger boobs than before.

I quickly set an alarm on my phone to make sure I woke up before her shift ended, then lay myself on top of her and took a nap in her warm embrace.

The alarm woke me up after fifteen restful minutes. I extricated myself from Jade’s boobs, put my clothes back on properly, then returned Jade back to life.

She took a deep breath and sat up on the air mattress. Her jeans were on her legs again, after having vanished with them when she had been altered. She looked up at me with a dreamy look on her face. “That was the best thing I’ve ever done in my life.” She paused for a moment in contemplation. “Can you take me with you? I wanna do it again tonight.”

“Hold on, you want what? I live with my mother and sisters, they’d ask questions!”

She eyed the Alterscope in my hand. “So use that thing to turn me into something small! You can turn me back in your room, then we can have some secret fun! What do you say?”

“Don’t you have people who would miss you? I can’t just take you away!”

“I live together with my sister, but she’s used to me spending the night at some guy’s house, it’s gonna be fine.”

“So I’m just another guy? Some one-night stand you can have your fun with and then leave?”

“Oh no, this is far too good to be just a one-night stand for me. I want to do this on a regular basis. Your friend with benefits, if you want.” She looked down at her boobs, which were still bigger than normal, although they lost their ridiculous balloon shape. “And these are some pretty large benefits.”

“And you’re just… cool with this? With me turning you into a thing for my pleasure?”

“You should really have a go once, see how it feels. Maybe then you’ll understand what I’m going through right now. Every touch is bliss, and then the ecstasy of fucking… it’s almost too much! And when you came in me, I… I still feel your cum inside me, and it’s like pure honey and sunshine! I never want this to go away!”

I felt a little creeped out at that description. “Hold on, you’re talking like an addict! I’d rather you come off the high you’re riding right now and make a rational decision for yourself. As much as I’d love a woman who offers to be my guilt-free fuck toy any time I want, this seems too good to be true… and I don’t want to destroy your life with this.”

“Honey, you’re not destroying my life—the complete opposite in fact! When I was lying there with you pumping into me, I felt like I finally had a purpose! Like I could finally do what I was made for! Please don’t take this away from me, I’ll be your test subject all you want!”
