Katie crawled in through her bedroom window and dropped to the floor silently. She reached back and closed her means of entry, drawing the blinds shut before striding across the room and flicking the light switch on. She turned to the mirror, and watched as the snarling green alien it reflected grinned back at her. Her arms stretched out before her, an almost rubbery coating of scales adorning them. She wriggled her toes, unable to sense or feel her fleshy human toes inside the slightly longer and clawed toes of the reptilian alien she wore. She dragged one of her long claws down her cheek, hooking the scimitar like appendage into her mouth and giving a soft tug.

The green skin lifted from her own. The latex-like surface distorted and stretched unnaturally, revealing pale skin glowing with a soft pink blush underneath.

Katie wasn't always a green skinned, tentacle-esque haired green alien with claws and scales. This morning she was a normal human girl, and then everything changed.

Her day had started like any other, and she woke late in the afternoon. Her 'profession’, if you could call it that, demanded her to be awake when others were not. After a light breakfast and plenty of exercising, she went to check her mail, noticing a strange cardboard box at her front door without a shipping label. She wasn't expecting anything.

She hurriedly pulled the box inside and studied it. It wasn't at her door last night, so it must have arrived today, but she hadn't seen or heard it come. Tearing into it, she was even more confused and hesitant. A strange, slippery material flowed through her hands as she attempted to lift it from the box, pooling back into the box. Finally grabbing a sufficient hold on the item, she held it in front of her to get a better look at it.

It was a rubber - no, it was latex, she corrected herself - bodysuit, in varying shades of green. Katie had tried out her own latex bodysuits, usually black though and never with an attached hood or gloves like this one. As she pulled it from the box she noticed a note at the bottom. “A gift. It will help you in your line of work. -A friend.”

She frowned at the implications that someone knew she was a cat burglar, but it seemed they didn't intend to turn her in. Perhaps they'd have her work a job in exchange for the suit, in which case she better see if she even wanted to keep it. She examined it, looking for a zipper or some other way in. The only openings were the suit's mouth, and its two lower holes. She started pulling at the back, trying to find and separate and opening when it ripped apart.

She stared, partially in anger and partially in shock. Normal late suits don't just tear apart, they stretch and pull long before that happens. It wasn't until she watched the suit seemingly mend itself, pulling the hole together until it completely vanished that she was reassured, and even excited. No chance for it to open during a heist of her's.

She quickly stripped down, though she wasn't sure why. She normally wore her suits with at least underwear, if not some material to help prevent chafing. But something about this suit, from it's long toes and fingers adorned with heavy claws, to the intimate details of it's breasts and genitals spoke to Katie. She felt a suit so personally detailed only could be appropriately worn with her own 'intimate details’.

Forcing the rubbery green material apart again, from neck to anus, she marveled at the pink insides. It looked soft and cushioned, and excitedly she slipped her right foot through the new hole and into the appropriate leg. As she filled the suit, she watched as darker green muscles swelled into form. Her toes made noticeable bumps as they slid towards their home. Each toe popped into place, the stretchy material forcing snuggly around and between of them.

Katie couldn't stop herself from panting as she wriggled her toes against each other. The suit felt strangely tight, as if it had suctioned itself against her. That meant she could feel as her toes rubbed against each other, the microscales on the suit's surface catching and tugging their surfaces. She reached her fingers between each of her toes and gripped onto her foot, giving the suit a soft pull. It was nestled in against her and was reluctant to shift in anyway.

She licked her lips, her excitement building.  She shoved her left leg hurriedly, taking less care this time. She could almost feel herself drawn in by the suit, the sheer tightness seemingly pulling her in. Pulling the legs up like pants, she felt the hips of the suit reach her own, and a pair of tube like appendages tickled against her sex. She blushed, doubting if she should continue. The suit assuredly was made for longer term use, making the detailed vagina and ass functional.

She gulped and forced the suit up. It wasn’t as difficult as she thought it would be, the suit seemingly to almost ‘intelligently’ work its way into her holes on its own. It offered little resistance climbing her body as she pulled the firm green abs against herself. Her career required her to be in shape, but she wasn’t as perfectly flat and smooth as this suit made her look. She liked it, even if she was missing her belly button and her breasts had vanished into the generous cups the suit sported.

She finished slipping her arms in, and looked into the face of the mask. The sclera of the eyes was pure black, and she wondered if she’d even be able to see out of them. She gave herself a few deep breaths before pulling it over her face. The hood had its own appendage that forced its way into her throat, suffocating her momentarily before she was able to breath again through it.

Shuddering, Katie made her way to her closet mirror. The seam in the back of the suit was closing itself, she could tell. After a moment, she was sealed in. There was no sign of the pale redhead in the mirror. She looked for any resemblance, any shape of her own body that distorted the suit. There was none. Katie was gone, non-existent in her rubbery prison. Instead, a green alien stood and stretched, admiring herself. Being able to vanish and become unrecognizable sure would be useful, Katie thought to herself as she walked away from the mirror and began to prepare for the night’s heist.

===

Katie pulled at the skin of the suit again. It didn’t seem to tug away from her skin the same way as a moment ago. She rubbed the back of her head, the thick and tentacle like strands of the suit’s hair running between her clawed fingers.

Digging the claws into the suit between her breasts she pulled at it, trying to separate it into a seam like before. It started to part, before snapping back together. Maybe it wasn’t going to let her out until she removed her haul?

She sighed. During the heist, she had to be a bit more… creative when it came to finding a spot in the suit to put what she took. She hadn’t much time to think, and it’s not like it came with pockets, except for a couple more organic pockets. She squatted down, blushing red inside the suit and glad she was alone in her home this time. Reaching down, she parted the elastic lips of her green vagina, pulling out handful after handful of gems and jewels set in various pieces of jewelry. Katie felt horribly embarrassed, and a glance in the mirror revealed this was as strangely lewd as she thought it would be.

She quickly pulled away her hand once she finished, and looked down at herself. Maybe she was overtired, maybe it was stress or nerves. She wasn’t getting the suit off tonight, anyway, so perhaps she ought to go to bed.

“What do you think you’re doing? Giving up, already?”

Katie froze. The voice sounded close, almost behind her. She had checked and made sure she was alone in the apartment. She spun on her feet. Silently her feet padded through the apartment, the only sound was her claws clicking over the hard floors. “Hello?” She called out, cautiously. She was off her guard, and that made her feel vulnerable. Weak.

“Where are you running to? Like a child, running to her mommy.” Katie’s ears burned red. “Don’t bother looking for me.” The voice seemed to be taunting her, giving just enough pause between each remark for her to almost react. It was keeping her feeling awkward, being nearly interrupt each time.

“I’m you. Or, a part of you, inside the suit now. A mysterious bodysuit shows up at your door and you can’t help but put it on? I bet you feel so sexy in it, don’t you?” Suddenly Katie felt herself moving. The suit, with all its synthetic looking muscles, overpowered her and forced herself to stride to the mirror. Katie’s naturally stealthy gait led her to spend much of her time partially crouched over and watching her steps. The suit was making her strut sexily, her head held high. As she stood and posed in the mirror she admired her legs, leading down to her feet. They looked more feminine than her natural feet with their more delicate arch and their perfect toes.

“Yes, that’s it. You’d be happy to let me be in control, wouldn’t you? Just give up, let a real woman who knows how to use her body take the lead.”

Katie shook her head, snapping out of the haze. She broke out of the pose the suit was holding her in. She had to get this thing off of her, immediately. Collapsing to the floor with a thud she felt almost too well through the walls of the suit, she started aggressively clawing at the covering on her feet. The suit peeled back like scraps of rubber, curling away from her pale feet. Her toes popped out of each of their appropriate pockets in the material. She panted, watching her sweaty toes glisten exposed to the room. She felt a chill run through her as her skin was exposed to the air for the first time in hours.

Laughter started softly, in the back of her mind. The suit, surely. “That’s cute, did you think you won?” A flurry of fleshy tentacles extended out from the rips in the suit Katie had made only moments earlier. Each was only an inch or two long, but the sheer quantity of them made it seem like an undulating sea of the appendages reaching out from against her. They pulled the shreds of rubber back down, fusing it back together. As the tentacles pressed against her skin, she whimpered softly. They were cold and wet. She could hear them moving around her, making wet slapping and sticking sounds. It sounded like a pot of wet pasta; wet surfaces rubbing against each other and her, and sticking to her skin before peeling off with a slimy residue.

Katie watched helplessly as her progress was eaten away. She bit her lip, the suit’s sharp teeth digging into the suit’s green slick lips. She felt all of it, even though she shouldn’t be able to feel any of it. It was a suit, and she was the person wearing it. She should be in control!

She grabbed hold of her toes, slipping her fingers between each of them in a mad panic. She wouldn’t let the suit just bury her again without putting up a fight. The fleshy nubs forced themselves under her fingertips, worming between her and her iron grip on her toes. She watched the green skin crawl over her own, her pale toes succumbing to their intimately tight embrace inside the suit before her claws reformed over her plain human nails.

Katie shot to her feet, struggling to claw off as much of the suit as she could. Each rend was repaired quickly, the tentacles pulling their pulsing masses across her flesh as quickly as she could pull them apart. In her wrestling, she staggered around, fighting the suit for control until she collapsed in her bed.

“Give up. I’m all the best parts of you: your willpower, your confidence, your sexiness, your strength. I could make you so much better, because I’m better. I’m what you always wished you could be. I’m a real woman, powerful and in control. You’re a puppet inside me.

“But don’t worry. I’ll make it enjoyable for you too.” Katie gasped, her body shaking as the suit revealed it’s final surprise. The tubes she had fitted into herself earlier had begun their own assault into her holes. She whimpered, feeling the appendages in her mouth, ass, and vagina all swell, pushing and teasing deep into her body with their newly phallic shapes. She passed out shortly after, from the exertion of fighting the suit along with the unique torment she was receiving at its clawed hands.
