The Black [Man to Rubber Woman TG]

Commissioned by FlyingBatman

Dave finds a mysterious black substance slowly spreading over his skin. It should make him worried but instead it seems to be making him horny, and making some lovely physical changes.

~

I’m one of those people who doesn't ‘wake up’ right away. My alarm goes off, I roll myself out of bed, shower and get dressed, but I’m not really there till after my morning coffee. Which is why it's not surprising I missed it at first. It was only when I was sitting on the train, slowly letting the caffeine seep into my system, that I felt something tingly and odd on my chest. I pulled back my shirt to reveal a tiny black patch of…something, sitting on my skin. Curiously, I pressed a finger to the substance and found it smooth, like rubber. Black rubber. 

Considering I worked in finance, I couldn’t think of a way a bit of black rubber could have melted onto my chest, let alone without me noticing. But the train pulled up to my stop, and I shrugged it off; I’d wash it off in the shower tonight. It didn't hurt, in fact, I could barely feel it at all, and I had a huge list of tasks to get done today. Whatever the mystery substance was, it could wait.

At least that’s what I thought. 

As I sat down at my desk to start typing, I felt hyper aware of that little spot on my chest. It made my skin tingle strangely, and it seemed to be getting bigger. A little voice whispered in the back of my mind, ‘Go to a doctor’, but then I laid eyes on my full-to-bursting inbox, and the voice of reason was quieted. Besides, it didn't hurt; it just felt…tingling. It was almost nice. 

I tried to focus on work, but it was impossible to ignore the strange, heavy feeling in my chest. As the day went on, that tingling got stronger and spread from the centre of my chest all across it, even to my back. 

“Hey, Dave? Are you alright?” Asked my supervisor.

“Fine, I just have to go to the bathroom!”

I quickly stumbled to my feet and walked as quickly as my legs could take me. With every step, it was more obvious that something was wrong. I could feel a sway to my shoulders that had never been there before, and a strange jiggle and weight hanging off my front. I made it to the bathroom and locked the door, ripping open the buttons at the front of my shirt to reveal the spot had grown, a lot. 

It was covering my entire chest now and had wrapped around my back and shoulders like a sports bra. The likeness was even more apt thanks to the two round mounds growing out from the middle. They were obviously breasts, supple, detailed, silky smooth, black rubber breasts. Complete with nipples. 

“What the hell?”

I ran my hands over them; they were slightly stiff, but still had some give. They were certainly harder than the real thing, but it didn't change the fact that as I pressed my fingers to the ‘skin’ a bolt of pleasure shot through me. It made me gasp, and the black rubber covering me began to creep downwards. I thumbed over the nipple, surprised to find it felt real. It was like this weird body suit was actually part of me. 

The black continued to creep down under my clothes, smoothing over my stomach and subtly changing its shape. The shock wore off after a moment, and I snapped myself out of stunned stillness. 

“Get off me!” I hissed, trying in vain to dig my fingers into the black substance and pull it off. It was useless. It was fused to my skin, it almost felt like more than that, I swore I could feel it seeping into my skin, becoming part of me. 

The black substance slowly crept over my buttocks, and as it did, it swelled. I moaned despite myself, feeling my butt get rounder and more bubbly. My hips, also coated in black, seemed to grow wider to accommodate and as the goo spread down my legs, they became thicker, ready to support the weight of my new peachy ass. Whatever this stuff was, it was turning me into a woman! 

And it felt…good. 

The more the black spread over my skin, the more pleasant that tingling sensation became. It was like a lover trailing fingers all over my skin, leaving heat and desire in their wake. With trembling hands, I buttoned my shirt back up, right to the collar, so none of the mysterious substance would show. I could still feel it, though. There was no ignoring the changes that were taking place beneath the thin fabric of my clothes. 

My pants were tight across my ass, and getting looser over my calves as the black slowly spread over them as well. The front of my shirt was getting tighter as my new breasts continued to grow. I wouldn't be able to hide them for much longer, or stop myself from making sinful noises if that pleasure didn’t stop. 

I could feel the rubber slowly coating my body, surrounding my thighs and legs, my crotch was untouched so far, but it was only a matter of time. I shuddered to think how good that would feel. As if in response, my breasts continued to grow with my arousal.

This was insanity. I didn't even know where this strange black substance had come from, and now it was transforming me from the outside in. And it truly was going in. I swore I could feel parts of my insides rearranging. And yet, it felt so good, it was hard to panic. How could I worry when pleasure was soaking into every pore the delicious goo touched? 

I groaned in delight; there was no way I could stay here. My new nipples were already straining against my shirt; soon, there would be no hiding my new womanly curves. I had to get out of here.

I can’t remember what excuse I came up with to leave, pretty sure I could have said anything the way I was staggering around, all pink in the face and glassy eyed. My boss probably thought I was running a fever: in reality, I was hot alright, just not in the way he thought. 

I stumbled into the house, barely able to stand. My entire body felt like it was on fire, I couldn’t remember a time where I felt more horny. As I staggered to the bedroom, I shed my clothing, letting it fall where it wished, along with a few drops of the wonderful, ecstasy-filled black goo. I was sad to lose some, but I can't think about it now. I needed…I needed, actually, I wasn't sure what I needed. I decided on being totally naked to start with. 

I fell onto the bed just in time to watch the black cover my crotch. I moaned, watching as my cock reshaped before my very eyes, turning shiny, black and smooth. A plastic pussy, just for me. The pleasure seemed to double, and I moaned, shuddering in pure ecstasy as I felt the black changing me inside and out. 

I reached down and clutched my shiny black legs, not to rip the substance away, but to try and spread it to my hands. It worked. The black goo spread over my fingers and palms like gloves, slowly hardening into that rubber-like substance. Experimentally, I ran my fingers over my legs and moaned; it was like the rubber was making everything more sensitive. Even my fingertips tingled with delight as they left streaks of heat across my new fake skin. 

The black was spreading over every inch of me now, seeping between my toes, the webs of my fingers, and creeping up my neck. The idea of it covering my mouth should have scared me, but it didn’t. It felt too good to resist. I felt that black rubber coat my face, reshaping it into something more feminine. Even as it seeped into my skin, mouth and nostrils, I never struggled to breathe. I could fully enjoy the sensation of my lips plumping and my new rubber lashes growing heavy. 

Part of me wondered if I was even human now. What was this strange goo that was changing? Those thoughts immediately disappeared as my fingers brushed over my new pussy. It was like electricity, pure pleasure, purer than anything I had ever felt, filled me. There was no way a normal woman would feel this way; it had to be the goo. The glorious, ecstasy-filled goo. 

I circled my new rubber clit and moaned; what started as a low, male moan turned to something much higher as my Adam’s apple melted away. I was now completely encased in the black substance, at its mercy, and I loved it. I kept rubbing my new clit, feeling the pleasure reach new heights until finally it became too much. 

With a shudder, I came, and the rubber seemed to react, all of it buzzed, spreading the pleasure over my entire body. Droplets dripped from my pussy and onto the sheets, some even splattered to the walls and began to grow.

Yet, I wasn't satisfied. My finger didn’t even slow as I continued to finger fuck myself to greater heights. The ecstasy didn't show any signs of letting up, so neither did I.

I balanced the phone between my ear and shoulder as I shoved the door open. 

“I’m just Dave’s roommate, I don’t know him that well.”

“Well he went home acting very strange this afternoon,” His boss continued, “your number was listed as the emergency contact, I just thought I should let you know.”

“Okay, well, you have, I’ll call you if he has food poisoning or something.” 

I still don't know why this guy was calling me. Dave and I met online because we both needed a roommate to afford rent. I barely spoke to the guy. He was a white-collar worker, I was blue, he was upper-crust, and I was from the rough part of town; the only thing we had in common was our current address. Still, the fact I was his emergency contact is pretty sad, i knew he wasn;t the most social guy but come on. 

I dumped my work bag and kicked off my boots with a sigh of relief.  My bones were aching as all I wanted to do was flop onto the couch and watch football. Then I felt something squash under my sock. 

“Ew…”

It was some sort of melty black substance. There were drips all over the floor, leading from the hall to…Dave’s room.

“Ugh, did you try to cook or something?” I yelled, trying in vain to wipe the substance off. “Gross, what is this?”

It spread to my fingers, then my jeans as I tried to get rid of it. If I didn;t know any better I’d think it was growing. 

“Hey! Dave! I don;t care if you’re sick I am not cleaning this up!”

I stormed down the hall toward his room and flung open the door.

“What is this stuff any…way…?”

My voice trailed off in shock; I didn't know how to process what I saw. The whole room was covered in a shiny, black rubber: the furniture, the walls, even the figure on the bed. She was utterly gorgeous; with a perfect set of smooth tits and shapely long legs. At first, I thought it had to be a sex doll of some kind, but then she blinked; black eyes behind black lids, and her shiny lips smiled at me. 

“Oh, Liam, isn't it wonderful?” She moaned, “Oh, it just feels so good, I can’t stop.”

My eyes were instantly drawn to her fingers, they were thrusting in and out of her rubber pussy and my mouth went dry. Arousal flared inside me, and my skin started to tingle. This sight was alien, and yet, it was the most erotic thing I’d ever seen. 

“Dave?”

“Yes, oooohhhhh…it changed me, it’ll change you too. Don’t fight, it feels so good…”

That tingling sensation got stronger and I realised, to my horror and delight, that the black substance on my fingers, feet and pants was the same black rubber coating Dave. I looked down in time to see it soaking into my clothes, melting into them and then, my skin. 

“It took ages to change me, but it’s stronger now,” Dave groaned as his finger swirled over his clit. “I’ve fed it with my pleasure, you’ll change faster…”

My heart raced as I felt it coating me, reshaping everything from my ass to my feet and then rocketing upwards. I should have panicked, but Dave was right; it felt so good. I felt my new breasts grow and stumbled into the strange black room. More goo sprang up to meet me, changing my body faster than I could keep track. Dave opened her arms and I stumbled toward them helplessly; unable to contain my own desire as the black goo changed me inside and out. 

My heart began to pound as she reached out, her fingers brushing against my arm. The sensation was electric, sending shivers down my spine. It was like every nerve ending in my body had come alive, responding to her touch with an intensity I'd never experienced before.

“Come, sit.” She beckoned, sitting up on the rubber bed and patting the space beside her. 

I sat, my body tingling with anticipation, as Dave settled beside me. Her thigh pressed against mine. She leaned in, her breath warm on my ear, and whispered: 

"Close your eyes."

I did as she asked, my senses heightening as I waited for her next move. The goo was coating my face now; I could feel it burrowing between my legs, changing me to be just like my new rubber sister. Dave’s fingers trailed down my arm, each touch sending waves of pleasure coursing through me. It was like every nerve was on fire, responding to her lightest caress with an intensity that left me breathless. I gasped as her fingers grazed my breast, the sensation overwhelming in its intensity. 

"Oh God, Dave," I cried, my head falling back onto the bed. “That's... that's too much."

But she didn't stop, her hands continuing their sensual exploration, mapping every inch of my body with a slow, deliberate touch. I was lost in a sea of sensation, my moans and whimpers filling the room as she teased and tantalised me.

I shuddered and reached for her; my movements became more urgent, more desperate. We shed the last vestiges of our inhibitions, giving in to the overwhelming sensations that the black substance gave us. Our bodies moved in sync, a dance of flesh and rubber, as we explored each other with a feverish intensity.

Dave's mouth found mine, our lips locking in a deep, hungry kiss as our hands roamed over each other's bodies. I felt every nuance of her touch, every subtle movement of her fingers, as if my senses had been dialled up to eleven. If there was any way to get out, to transform back to my old self, I didn't care. Not even sex with the best porn star in the world could feel this good. 

Our breaths came in short, sharp gasps as we rolled across the bed, a tangle of limbs and rubber. Dave's hands slid down my body, her fingers slipping between my legs, and I cried out, my body arching as pleasure exploded through me.

"Oh fuck, Dave," I moaned, my voice hoarse with need. "Don't stop. Please, don't stop."

My own fingers found her pussy and we continued, lost in a world of sensation and pleasure, the rubber enhancing every touch, every caress, until we were both trembling on the edge of release. Our bodies moved in perfect harmony, a symphony of moans and gasps, as we pushed each other higher and higher, towards an explosive climax that left me breathless, yet hungry for more. 

Without hesitation, I pulled her to me and we continued to fuck, pressing our new pussies together. And as we lost ourselves in each other once more, the black enhancing every touch, every sensation, I knew that I wouldn't have it any other way. 

“We…we have to share it.” Dave moaned against my neck. “We have to share this pleasure with the world.”

“Yes!” I cried, “We’ll go out, we’ll spread it everywhere!”

I came again, and the black goo responded, shivering all over my body and sending Dave into another orgasm as well. This was the new us, and soon the whole world would share in our pleasure. I couldn;t wait to get started.
