Demoness Mask

, , , , , , , ,

In which I am a mask, and consensually possess and transform someone, while leaving a parting gift after I'm done. I wrote this in a quicker burst of capitalizing on a mood for masks and possessions a friend sparked in me.


Julie let out a soft gasp as she stepped through the large double doors into the store. She hadn't expected too much from a magic shop, but the air in here felt quite mystical somehow. The warm glow, the soft couches, the large mirror on one wall, the glass displays all made it feel cozy, and there was a surprising variety of things set inside them. Some were expected, like stage magic kits and crystals, while others were things like clothing and snacks.

Walking around, she saw one thing in particular that caught her eye. It stood out, being set haphazardly on the counter next to the cash register, seemingly abandoned. It was a purple mask, shaped like a cat's face. A darker portion covered the eyes, and horns stood up in addition to ears. It felt almost magnetic, but she put it back down, ringing the service bell to see what to do with it.

She waited. And waited some more. She rang the bell a second time, but no one came out to see her. The shop said it was open outside, but there was nobody inside other than her it seemed. She picked up the mask again, finding a small string to hold it onto her head with. With a mental shrug, she stepped over to the mirror, and slid it over her face.

Her green eyes were visible through the holes of the mask, once she got it on; her pale skin was visible on the lower part of her face, her jaw uncovered by the small thing. She did a little spin to show it from all sides; it was a cute addition to her wardrobe, even if out of place when she overwise had a simple shirt and skirt combo. But as she looked again, she saw something odd, as her eyes flashed to red, soon joined by an uncomfortable but mild headache.

She quickly pulled the mask off, not minding the string snapping. She looked into the mirror, her eyes still red, faintly glowing even, but with the mask off the glow faded and they turned back to their usual green. She looked at the mask, on the floor, alarmed. "What is this?" she thought, trying to figure out what was happening. She believed in magic, yes, but never experienced something so direct.

And yet, she felt compelled to put it back on again. Not just because of its attractive power, as it looked for a wearer, but also simply to sate her curiosity; she had to know what this thing's deal was. And so, with some hesitation, she bent down, looking it in the eyes before holding it to her face.

As she held it in place, its power kicked in, Her headache returned, her eyes shifted once more, and now it stuck itself to her body, a painless yet bizarre sensation. The longer she wore the mask, the more right it felt, like she was supposed to be wearing it, like it was meant to be part of her face. She touched a hand to her cheek, the seam between mask and skin still there, yet feeling less so as time went on, and she heard a voice, both inside her head and from outside it at the same time.

"Ahh, this is..."

Julie was alarmed at the voice; she wasn't used to hearing multiple voices in her head that were out of her control, and certainly not hallucinating them in any way. She looked around for the source, before realizing that the voice was coming from her mask and stammering out a response.

"W-who are you?"

If the stiff mask could smile, it would. She could feel a comforting warmth coming from it, it's presence trying to help put her at ease as best a sapient mask could.

"You may call me Lily~ Normally I run this shop, but, well..."

"You turned yourself into a mask?"

"Yeah, I kinda messed up the duration for something I was working on... never test on yourself without a spotter!"

Julie nodded, confused by how this was possible but following along. She walked around a little, still looking into her reflection, faintly seeing the outline of something human and not at the same time.

"I... I want to help, but..."

There was a small giggling noise coming from the mask, before Lily spoke again.

"You can't do magic like this? Don't worry, I have a more... direct method."

This was making Julie a little nervous now, the mask a bit intimidating. What did she mean by direct method? Her skirt swished, a tingling going up her spine as she squirmed a little.

"I want to, well, possess you; let me take over for a few days, I'll handle all the hard stuff, maybe give you something in exchange~?"

Julie shook her head a little, the swishing going all the way down to her thighs. She looked into the mirror, the purple striped, fluffy tail pushing her panties down and making her skirt lift upward. It was cute, especially with the mask, and felt nice... but she couldn't just up and give herself up to someone else, not now. She had her job, and her friends... Plus, she wasn't completely sure how much she would want to give up control to someone she just met.

"I'm sorry, but, I don't think I can do that right now..."

"I understand! Just, leave me here, alright? And if you change your mind, or find someone who is up for it, you know where to find me!"

Suddenly, the mask began to pull away. Within only a few seconds, Lily was pulled away, and Julie was just by herself again. The red eyes and tail took a few solid minutes to disappear this time, and she spent them all feeling up the fur before it vanished. She continued to think on it as she set the mask aside, tucked away behind the front desk, then did it more when she turned the store's sign to "closed", and did so some more when she walked home. By the time she reached her apartment, her mind was made up.

When her usual weekend break arrived, she called her job.

"Hey, is it alright if I take one of my vacation weeks now? Yes, yes I understand. I know it's sudden, just a personal break to spend a bit of time out of the joint. Yeah, thank you!"

Her time off secured, now was the time to call and text her friends, online and in-person. She gave them similar stories, telling them not to worry, that she simply wanted some time to be with herself. This was, of course, a lie, but she could save the truth for after she could prove it.

--

Her sleep that night was poor; the mixture of excitement and nervousness messed with her ability to rest. Still, she was invigorated enough by what was going to happen that she returned to the store far more quickly than she'd taken to return home the first time.

When she entered the store, she quickly went over to the mask, relieved it was still there. No one had broken in either, everything was left as is. Looking to see if anyone else was watching, she set the mask on once more, standing before the mirror as she felt the headache return, less uncomfortable than it had been before. Already she was getting used to it, it seemed, but that was fine by her. With the red glow returning to her eyes and the tingling in her spine, she heard Lily's voice once more.

"Ah! Back so soon? It's a bit hard to tell when I'm an object..."

Julie gulped, before nodding. She looked over herself, the red eyes in the mask, the tail gently swaying over the shorts she chose for today. Her brown hair and purple mask framed each other perfectly. The tail was so comfortable, in a way she had rarely considered before. She felt like she had to do this, even if it meant giving up control... which, weirdly, felt good. It'd be a nice break from being her own person for a bit, no doubt.

"I've decided, I wanna do it."

"Oh? Does my new friend want to be my new host?"

There was a pause, as she made sure of it to herself.

"Yes. Please, possess me, make me yours. Just, make sure I'm back in a week, alright?"

"Hehe, of course! Now, try to relax..."

Julie tried to do as she was told, closing her eyes as her mouth adjusted its shape, nose melting into the mask, muzzle pushing itself forward. Fur was spreading over her skin, and she felt odd ripples in her shoulders. "Oh, by the way, you might want to strip."

It was a bit hard to focus; with her hands and feet turning into paws and scales adorning her chest, her whole body was filled with pleasant tingles. But at the same time, her mind was losing connection to her body; Lily was taking over, while Julie was dissociating. It was odd, not entirely comfortable, but she was still excited, as Lily flexed an arm experimentally.

"Oh, I guess I'll do it myself. You just rest, dear~"

Julie nodded in agreement, feeling Lily pulling her clothes away, one piece at a time. The shirt and bra got top priority, allowing Julie to watch her tits swelling up a little, her nipples the first spots to glow within her fur and scales. A similar sensation to her tail growing in hit her head, white horns sprouting from her scalp as they merged with the ones molded on the mask, ears growing out into points to match.

The true reason for taking off her shirt became evident as her shoulders burned, two new limbs sprouting from behind. Soft feathers covered them, growing out nice and long, and Julie gave them a few flexes while she was still able to control their shared body. Lily, meanwhile, pulled the rest of her clothes off, allowing her tail more freedom, her clit on display as it grew longer and harder, developing into a cock with a soft sheath around the base.

Julie would blush if she still had control of their body, but the warm feelings she was sharing with Lily made it clear how she was pleasantly surprised and infatuated by her body. Lily struck a few poses, letting Julie take in the massive wings, soft paws, sharp horns, and adorable fur. With a dark purple collar around her neck, and her scalp's hair shifting to a deep, dark blue, the changes were finalized.

It was a bizarre mix of feelings; Julie had a new body, and someone else was piloting it. She could still sense things around her, but she wasn't in the pilot's seat; suddenly being someone's headmate was an odd thing, but she was still enjoying it somehow. Her mind began to drift away, into a soft sea of purple waters; before she surrendered entirely, she watched as Lily looked at a note she'd left on the counter.

"Oh, my~ that's quite interesting! Well, I'm sure I can arrange that..."

--

Julie felt herself lying on a long couch when she started to get pulled back out of her mental slumber. She groaned a little, looking around the backroom of the store she was in, a comfortable mix of office and lab with various equipment pieces on one side and a comfy lounge on the other.

As Julie got onto her feet, she saw Lily standing by the door, busying herself with some papers. Julie only now noticed how inhumanly tall the purple furred demoness was, despite how they'd been sharing a body before. She let out a small cough, letting her host know she was awake.

"Oh! Good to see you're up. How do you feel?"

"Groggy..."

Lily purred, loud and deep enough to hear, taking the smaller human's hand. Julie was still naked, so they could both see that her body was in its original state; smaller chest, human skin all around, and a slit instead of a cock. Lily, for her part, had a light dress, dark grey with holes cut for her wings.

"Good to hear! Don't worry, it's only been about three days or so, so you'll have plenty of time left to relax."

Lily kept talking while she guided Julie to her own clothes.

"Such an interest list of notes you left me: 'please take full control, you can use me for sex, i want you to jack me off...'"

Julie could only blush as the demoness read the demands off, pulling her shirt on. Fully clothed, the two returned to the entrance, where among the various goods that had been shifted, sold off and added, was a conspicuous closed box with no labels of any kind, just behind the counter. Lily picked it up, offering it to Julie alongside a small stack of high value bills.

"And here's your reward for helping me! I'm sure you'll enjoy it, but save opening it for when you're someplace private, alright?"

Julie nodded, still blushing and smiling. "T-thank you..." she said, sticking the bills into her wallet and grabbing the box. Before leaving, she tapped Lily's shoulder, gently kissing her muzzle. It was her turn to blush as she watched her new friend leave the store, her gift in hand.

--

Once back in her apartment, Julie eagerly opened up her box. Inside was a soft, padded case, holding a note, a pair of bottles with a dropper, and most noticeably, a mask. It was similar to the one Lily had been; an animal's upper face, specifically a cat, with purple colours and ears molded into the top. Unlike the other one, this one lacked horns, and the detailing was light stripes on the cheeks. Julie almost pulled it on then and there, but decided to check the note first.

"Hey Julie,

Thanks for lending me your bod for a few days! I figured since you seemed to like the changes, I'd gift you a fun little parting gift~ I'll leave the details vague, but I will say that this will change you without the possession, and if you want, you can use the purple bottle to make it permanent and the green one to undo the purple. And if you wanna get possessed again, you know who to call~

Enjoy~!"

She smiled, immediately pulling out the purple bottle and dropper. She looked over the label, carefully noting how much she needed, and quickly dropping it onto the back of the mask, watching it get absorbed into its surface, before sticking it onto her face, feeling the wonderful feeling of the mask fusing to her once more.

And yet, unlike before, while the mask was clearly part of her, it was still a mask, made of smooth plaster and plastic. Her eyes, although now a bright, deep blue, were clearly in eyeholes. Her human nose hid under the attached feline one. Her ears at least pulled up to meld into those on the mask, but they remained stiff, her face locked behind the mask. The feeling gave her thrills, tingling up her spine.

Of course, after a few moments she noticed her spine growing long once more. Her tail was the same as before, the same as Lily's, alternating dark and light bands and extremely fluffy. She curled it around herself, nuzzling inside it. Some hair on her arms and legs grew thicker, furrier, shifting to fur as pawpads formed, fingers growing slightly puffier, feet turning into full paws that mixed standing on her soles and toes. Soon, her shoulders felt funny, and she quickly pulled her shirt away to make room for her wings.

And they grew in quickly indeed, although this time noticeably different; they still had the characteristic purple, but these were different, full fingers extending out, connected by thick skin. Fur grew over them much more lightly, as her bat wings stretched themselves out, a muscle she'd rarely exercised before. And with them, her changes were finished.

She giggled to herself, pulling her panties and shorts away to expose herself fully. Her crotch was a bit fluffier than before, she noted, gently pawing at herself while looking into the mirror. She eagerly pulled out her phone, taking some pictures to commemorate the new body, reminding herself to ask Lily if she had any of their time together. She wondered how to explain to her friends that she had a new body, permanently with a mask on her face, until further notice, but that was a problem she could approach with Lily tomorrow. For now, she was going to take her advice, and enjoy some time to herself to explore her new body.

And also to modify her clothes. This transformation sadly didn't include her clothes, so she'd need to do some hasty tailor work to fit herself. Well, that was a price she was fine with paying. For her new form, she'd gladly pay almost anything.

And who knows? Maybe she could be the one to possess one of her friends next time...
