I giggled quietly to myself as I got back to my apartment. Art had let me borrow some of his older stuff to take home and try out, and I immediately grabbed the Recombiner. I was going to have some fun tonight.

I locked my room door, making sure my roommate was fast asleep. It was almost midnight, afterall, and she did have to get up early for her job. Fortunately I wasn't working at the time, so I had as much free time as I wanted. Well, I guess I was technically working for Art. It sure didn't feel like work though.

Wasting no time, I stripped. I didn't want to rip holes in my clothes by adding new limbs with the Recombiner. It really was just a lot easier to be naked. I scanned my body into the Recombiner's crystal modifier core. Art tried to tell me how it worked… I got some of it. But most importantly, he told me how to do a few interesting things… which I was eager to try out.

Wasting no time, I flipped through the options, eventually coming across the one I spotted during Art's demonstration, but couldn't possibly try in front of him. Before I did anything though, I wanted to make sure that I could easily restore myself… and, who am I kidding, modify myself at will. I pulled out a portal bracelet that I had borrowed from Art. Flying through the menu, I quickly gave myself an extra arm, with an eye in the palm of the hand, and attached the bracelet to the base of it. Soon, I had a detached arm with the Recombiner off to the side, so that I could modify myself into whatever I want and still be able to operate it.

"First things first…" I selected my crotch area on the Recombiner, and was greeted by the one I had my eye on. A few quick taps later, and instead of my pussy, I had a dick. Horny as I was, it already stood at attention even as it appeared. Touching it gently, I shuddered at the alien sensation. I was about to start trying to masturbate with it, when I figured I might as well go all the way, and placed a copy of my pussy on the palm of my right hand. "Time to find out which sex has it better…" I grinned to myself, and pushed my palm onto my penis. It didn't seem to matter that my hand wasn't even an inch thick but my dick was a good six-ish inches, it went all the way in.

Pumping furiously as I fucked my own hand, I was surprised when I came. I quickly yanked my hand away, and suddenly got worried that I hadn't used a condom. Crazy delusions and images of me giving birth to my own babies through my hand-vagina floated to my mind before I shook them off as I basked in the glow of my orgasm… well, two orgasms, I guess. How the hell does that work?

I had planned on keeping my penis for the rest of the night, but it began to get really annoying. How do guys live with those things? I erased it from my crotch, patting the smooth blank area lightly. I selected my right hand to get rid of the pussy on it too, but accidentally erased the entire hand. Going with it, I gave myself a foot instead, and turned my other hand into a foot too. Placing my new feet-hands on the ground firmly, I tried to lift myself up and stand on my new feet. I failed miserably, collapsing over backwards, luckily onto my bed.

I had feet, not entire legs, and I didn't have the upper body strength to lift myself up like that. Maybe if I weighed less… I deleted my legs, making it so that my body tapered off at the crotch. Like that, I easily managed to stand up on my new feet, taking a couple steps around the room. It was a little annoying to have everything upside down though, and I could feel the blood rushing to my head, so I gave up and just erased my head clean off my shoulders. I wanted to watch where I was going though, since my other eye was trained on the Recombiner. Trying to think creatively, I tapped my breasts, and happily found that I was able to modify them, too. I swapped my nipples for eyes, but quickly grew dizzy from the insane depth perception with eyes that were a good deal farther apart than they normally would be. Once I got used to it however, I was able to see just fine, even if my vision was a bit bouncy.

Just walking around was starting to get boring however, and my arms-with-feet were starting to get tired. I swapped my arms for regular legs, and gave myself new arms where my legs used to be. Since my crotch was empty, I remade my head growing from it, and erased my spare eyes. Standing in the mirror, I almost looked normal, if it weren't for the fact that my breasts were way down my body… and my torso was shaped wrong. It felt odd to have my breasts hang "up" my body too. This new shape was getting to be too much for me, and it wasn't even that interesting. So I decided to go for "interesting".

Earlier I had managed to give myself two heads, but not two different personalities. Art had shown me a feature that let me split my consciousness, so that I could effectively be two different people… albeit inhabiting the same body. Eager to give it a try, and to experience talking to myself, I first decided I would need another form.

I returned myself to normal (Art had shown me where the restore function was), and promptly gave myself a second head. I had to shift my original head over to the left so that there would be room on my shoulders. Not long after that, I activated the split consciousness option in my new head. I suddenly lost sensation from that head.

"…Hi." I offered to myself.

"Hey, Amy. I'm Amy!" my other head giggled. "And you're… we're not crazy talking to ourselves this time."

I really had no idea what the other me was thinking or doing. I guess it did work. I was taken aback when my body moved involuntarily.

"So I guess we both have full control over our body?"

"Looks that way." My left hand drifted over to my pussy. I wasn't moving it. Or, well, I was, but I wasn't.

"What are you doing?" I forcefully stopped my hand short.

"Oh come on, you know you want it too."

"Yes, but there's so much we could do to ourselves first." I grinned at myself. She grinned back.

"Wait, I've got an idea first." My body walked itself over to my dresser, and picked up the portal ring from the spare arm, pulling it around the other Amy's neck.

"What are you… Oh." Before long, she had her own body. The Recombiner couldn't handle making us into two actually separate bodies, so we had to use the portal ring to keep ourselves connected, yet separated. What this meant was that we still could control each other's bodies, and felt from both of them. I was reminded of this when my own right arm reached up and tweaked my nipple, without me doing it. The other Amy giggled and smiled at me.

"Okay, okay, how about this. We each just control our own body, no fooling around with the others'. It'll be better this way." I proposed. Other Amy nodded, and turned back to the Recombiner. "What are you doing?"

"You'll see." She winked slyly at me. "Go lie down on the bed."

I had barely gotten to the bed before everything below my boobs disappeared and I fell flat onto the bed. I tried to get up, but I had no arms, either. I felt myself being picked up. "Wow, you're light like this." She turned me right side up and propped me up against a pillow.

"So I'm just a bust?" I wriggled my chest a little, puffing out my boobs. "I feel like I'm just an object now."

"That's the plan. But specifically… a sex toy." Amy grinned as she pressed a button on the Recombiner. I couldn't really see what happened, but I could tell. My nose and mouth were gone, and in their place was my vagina.

"What the hell?" I exclaimed, "Wait, how can I talk… oh… that feels really good." I was speaking out of the pussy on my face. It was moving like a mouth, and I even had a tongue inside it. The problem (or the blessing) was that everytime I talked, or so much as moved my "mouth", it felt like I was eating myself out.

"I found a Hybrid menu on the Recombiner. It's like fusion. So I gave you a mouth-pussy." Amy grinned at me.

"Oh, wow." I couldn't get out much without shuddering in excitement.  "Uhn… so… what, am I just a… sex toy?"

"Yep." Another quick tap on the Recombiner, and replacing her vagina was a generously proportioned penis. I could tell where this was going. Another tap, and all that was left of me was my head, featuring a very prominent vagina-mouth-hybrid. "And this is going to be the best head in the world."

It didn't take very long for both of us to come. Other Amy lay on the bed, gasping in exhaustion, and I… well, I couldn't exactly move, and talking wasn't easy when I was still impaled on her dick. "You're… really talented with that mouth... vagina… thing." Amy gasped. I gave her a playful squeeze and she yelped. "Sorry." She pulled me off her. "Alright… now, I guess, I'll be your sex toy, if you want." She grinned. She eagerly restored me and handed me the Recombiner.

"Hm… I don't really have any ideas that jump out at me right now… I'll just mess around with you until I think of something." I said, flicking through the menus of the Recombiner. I idly changed the other Amy while I thought about what I could do to her, erasing her limbs, giving her extra mouths, random stuff. I found the Hybrid menu that she was talking about, and started going through the extensive list. I could technically fuse any part with any other part, though I wasn't sure what some would even do. What good would fusing the left and right arms do? I decided to try it out anyway.

"What the… that's really weird." I looked over to where Amy was trying out her new right arm. At first glance, it looked like any old arm, but it seemed to be able to bend in any direction. It could work as both a right and a left arm, at the same time. Her fingers could bend in both directions easily, and could even form fists facing whichever direction.

I went back to the menu as Amy messed about with her new arm. It was really distracting to watch her do things perfectly from her back. I decided to try out some more Hybrid stuff, and gave Amy a fused eye and mouth. It wound up that when she opened her mouth, there was a giant eyeball inside it. That weirded us both out, so I quickly undid it. Hair and arm? She now had an arm made out of long strands of hair. Apparently she could control each strand of hair individually, which made for some interesting moments as she teased herself. Nose and boobs? Small nostrils replaced her nipples. She spent some time going around smelling things with her boobs. Penis and vagina? Gave her a dick growing out from inside her pussy. Oddly enough, she could sort of retract it, and conceal it completely inside her so that she looked normal. It wasn't long before she was fucking herself from the inside by repeatedly moving her dick in and out. The pending orgasm made it hard to concentrate.

Then I tried combining her head and boobs. Amy's head noticeably seemed to soften. "What the hell… oh…" she began rubbing her hair-hand over her face. I couldn't resist, and reached out to feel it too, to confirm my suspicions that, yes, her head was indeed like a giant breast. "This is so weird… but so cool." She squished her head together and it compacted, distorting her face. I giggled. Her head was extraordinarily malleable and looked somewhat shapeless.

"Oh, yes! I've got it." I grabbed the Recombiner again, and reverted the rest of her body to normal, except the boob-head.

"Got a plan?" Amy asked, still feeling up her head. There's something you never thought you'd say.

"I'm going to turn you entirely into boobs!" I laughed, already fast at work at the Recombiner. I started with her torso, copying breasts down to the hips. Then, I used the Hybrid menu to turn her entire torso into the consistency of breasts. I immediately noticed (and felt) the effects as her body sort of flopped in on itself, now made of pure, soft, sensitive flesh. I ran a hand down her side, and she moaned. Hell, so did I. Something about the fusion made the breast hybrids far more sensitive than my breasts were normally. She was busy feeling herself up with all her limbs disappeared, only to be replaced by more boobs. She fell over onto the bed, unable to support her soft body without any muscles or external limbs.

"Hey, I was using those!" she exclaimed.

"Yeah, but now you have more boobs." She thought about this for awhile, then smiled.

"Fair enough!" She laughed, I watched amusedly as Amy tried to sit up, but without any structure to her body, she really couldn't. Her torso gave way, and she practically folded in half, face buried in her crotch. I winced, it looked like it hurt, though I knew it didn't. The breast-body was surprisingly malleable, and didn't seem to hold any one shape. I could probably twist her up like a rope and it wouldn't hurt, just turn her on. "A little help?" She asked, voice muffled by crotch. A tap on the Recombiner later, and she was now face-first in boob instead of vagina. "That doesn't really help!" she exclaimed.

I picked her up by her shoulder-boobs, spreading her out as I stood up, a tapestry of breasts, a little wider than I was normally. I ran a hand through her boobs. She grinned. "This feels really good." Of course, I knew that already. Our bodies were still connected through the portal. "Hey, you should use me as a blanket! We'd be so comfortable."

"Mm… you're not nearly big enough." I frowned, turning her around. After all, she was more or less the same size as my torso. A little wider when flattened, due to the fact that she was literally made of soft boob-flesh. I tugged at her sides, trying to make her stretch. She groaned a little, but she wouldn't stretch out nearly far enough. "I'd need at least two of you to do it properly."

"…well, why don't you turn yourself into boobs too? Then we can just wrap up in ourselves."

"…Hm." That did sound appealing. "But then who's going to work the Recombiner? I can't leave both of us limbless…" A thought occurred. "Wait a second." I flipped through to the Hybrid menu again, and tentatively fused my hand with a breast. Once I hit Accept, my hand went soft almost immediately, but still maintained a rough hand shape, though rather rounded out. I could still wriggle the individual fingers a little. I passed the Recombiner to the breast-hand, and tried operating it. It was tough, but I managed to fiddle with it until I fused my own head with boobs, and it softened.

"Success!" I shouted. Other Amy cheered. It wasn't long before I had reduced myself to the same state she was in, a boob-blanket. I left my arms though, so that I could tuck us into each other. I wove our soft breast-laden bodies around each other, so that we were raveled up in a tight ball of boobs, tucking in our heads next to each other in the center. Our heads were also fused with breasts, so it felt extremely comfortable to snuggle up next to each other. Finally, I erased both my arms, leaving myself identical to Amy, other than a single hand-breast clutching the Recombiner woven tight in our center. It didn't take us long to fall asleep, both exhausted, and in the most comfortable and pleasant sleeping position we'd ever been in in our life.
