Demoness Costume

The costume party was that night and Analise had still not figured out what she was going to wear. She was at the used bookstore, looking for inspiration, but it was not like she could sew something in under ten hours. At wits end, she was about to just go home and wear an orange shirt and a skirt and say that she was a hipster Velma when the cover of a well-worn book grabbed her attention. On the cover was a woman with bright hair. Her body clad in a black leather one-piece with matching arm length gloves and thigh high boots.

As she drew closer, Analise realized the woman's skin was bright orange and that her hair was a contrasting blue. Tattoos of a similar hue traced over the exposed skin of her shoulders, hips, and chest. The later two of which were considerably larger than average. A pair of golden, braided horns grew from the middle of her forehead to drape back over long, pointed ears. Gold on black eyes completed her ensemble.

Her fingers gripped the cover. There was a jolt like static cling. She turned the novel over to read the back, but the rear cover was only covered in blurbs. The art store was still open, she had been meaning to try out latex paint. Two hours later, she returned home with everything she would need.

She drew a bath first, reading the book as she let her skin soften in the hot water. The demon pictured on the cover was Kylbyi, the leader of a rebel faction opposing someone named Taulic. She assumed that was set up in some other story before this, because it was not particularly relevant to the chapters she read in the time it took for the water to cool. An intense shaving session followed until the only hair that remained on her body was on her head in a bun. She let the tub drain as she tried to figure out the best way to apply the paint.

At a loss, she put the stopper back in and dumped the two buckets into the tub. Settling down naked into the paint sent a chill up her spine as it squished between her toes and butt cheeks. She was starting to breathe a littler heavier from all the new stimulation. The feeling of it running down her chest as she scooped it up over her was like the caress of many tiny fingers. Laying back, the sensation of the excess running down her legs made her shudder.

When she began to rub it on her face, she noticed a different sensation. Until now, the layer of paint had felt more like a gauzy outfit than a second skin. As it began to dry and adhere however, she realized just how tight a fit this was going to be-and it seemed to be getting tighter, particularly around her bust.

While never exactly small, Analise was surprised to find how much flesh she cupped in her hands. It had to be a full extra cup size! Sure it was an effect of being sealed into the paint, she shrugged it off, but it was hard to ignore the building heat in her body.

Finally she was well coated and got out of the tub. There was only a little of the material left so she left it to dry so it could be peeled off later. Sitting at her mirror, she began to paint her arm with what she figured the tattoos looked like under Kylbyi's outfit. With each stroke, the heat and feeling of growing got more intense. Pressure began to build against her tail bone and ankles. Completing one arm, she felt a jolt run down it. Muscle definition she had not had before developed before her eyes.

Freaking out, she tore at the paint, only to actually scratch herself instead. Somehow, the paint had become her skin!

She threw the brush down. Her sigiled arm twitched and picked the brush back up. She grabbed her wrist, but could not stop her possessed hand from beginning to trace sigils on her other shoulder. Inch by inch her grip weakened until, at her elbow, her fingers left go.

[Look, you wanted the have the best costume ever, right?] A chipper sounding voice echoed in her mind. [Just relax and let me make you into the spitting image of me. You might even enjoy the new you.]

With the intricate lines finished, her arms itched as scales began to grow in, forming navy blue gauntlets up to her elbow. The sigils glowed ice blue over them. She tried to get up, to move away from the paint, but her legs refused to budge. Trapped in her own body, she could only watch as clawed hands traced lines over the rest of her latex covered body. By the second she looked more like Kylbyi. Her boobs were visibly growing now, swelling like balloons filling with water. Her hips, too, were widening, even as her thickening ass started to raise her up on the bench. She felt only a little bit of it, mostly just pressure and weight, as if her whole body was numb.

The pressure in her crotch grew more powerful as her body spread its legs. A clawed finger covered in paint traced circles around her mound. eliciting moans that rose from the pit of her stomach. With each pass, there was more plush flesh until her labia had been pumped to four times the original size and her clit was even more prominent. The sensation of bone knitting between her cheeks washed over her as a spade-shaped growth sprouted and then quickly grew to a length of tail that curved down to the floor and then back up to her neck.

Her new prehensile appendage joined in to the painting session, scooping up the blue liquid and tracing lines over her face as her fingers began to pinch her nipples. While gasping from the faint stimulation, as if feeling it through a fog, the itch from before returned as Kylbyi's horns grew from her forehead. Analise clenched her eyes closed as an acute burning sensation crashed into her. When she reopened them, the whites of her eyes had gone black.

In that time, her nipples and areoale had swollen and grown like crazy. The dark skin covered the front of her significant endowments, the curve of her tits now easily outside her shoulders. Her nipples themselves were each the size of her thumb. Even with her senses dulled, the claws dragging over her sensitive skin had her gasping even harder as her engorged clit twitched like mad.

[All right, looking good. Let's finish this up and get you to your party.]

She found herself getting to her feet as her claws dipped once more back into the paint. With splashes of blue on her hips, streaks ran down her legs to pool on the floor. With a crack, her feet bent upwards as toes became talons and her heel began to point. More scales spread from the tops of her feet up her shins and calves. She looked suitably demonic now, but could feel that Kylbyi was not satisfied.

Turning back to the tub, the remaining orange latex was still a pool. Scooping some of it up, the costume demoness applied it to her clit. Instantly, the organ swelled. It grew to the size of her nipples and then surpassed them before she could even realize what had happened. By time it registered, her new dick was already seven inches long, three fingers wide, and sticking straight out in front of her. Thickening veins pumped like mad under her skin pushing her to inflate even further as pre-cum beaded on the tip. It felt like an inch of length was added for every beat of her heart as it stood more and more erect until the glans was smacking into the underside of her tits spreading sticky fluid over her soft flesh.

[Okay, I'm happy with this.]

With that all of the sensations she had been feeling intensified as she was once again aware of her extremities. She dropped to her knees hard, wedging her cock into her cleavage. Overwhelmed, she began to thrust as pre-cum flooded between her mams. Hugging her boobs, she began to tilt backwards as her motions became more emphatic. Nothing had ever felt this good. She was sure nothing else ever would.

Her body locked up with one particularly large movement, her member throbbing. A swelling sensation centered on the base of her massive cock. Two heavy weights slid down against her fat vulva. A feeling churning filled her newly grown balls. The churning became a roil as it rose through her twitching dick. In a rush, her first male orgasm hit her in the face. It was sweet on her lips and tongue. She licked the sticky fluid up and moaned as heat spread down her throat. The weight between her legs increased. Another blast of cum washed over her. The warmth sank in deeper. Stuck in this loop, her body continued to grow as wave after wave of arousal gripped her being.

Hours later, she roused to the sound of her ring tone. Staggering to her feet, she picked up her phone. Her voice was surprisingly sultry as she assured Courtney that, yes, she was coming. She was just about to head out the door.

Hanging up, she looked down at her body. Her tits were massive, each of them curving down past her waist and out nearly five inches. Her arms looked like she had spent her life doing crossfit. Not able to see anything else, she relied on the feeling of her clawed hands as they caressed her tight abs. Her bubble butt. Her foot plus cock and handful of testes. Her eyes fell on the outfit she had bought. There was no way it should had fit but, as she pulled it on, it felt like a glove.

"Oh yeah, I am totally winning this contest."
