"Get outta there you gross pervert!". Lisa's sister growled through the closed bathroom door.
Inside the bathroom Lisa scrambled to put on her scavenged clothes. Up early she had burrowed through her childhood clothes for something that would fit, the last of which was banished to the back of the wardrobe 2 years ago. She had had barely any time to shower afterwards, and was now in such a rush that she was sweating again. Her heart hammered as her sister banged again.
"Lisa get your ass out here. I need to shower too you know." Lisa grinned nervously at her sister's annoyance. She stole a quick look at herself in the mirror. Painted into clothes she hadn't worn in years, fabric straining even through her reduced size. She didn't know what had drawn her to pick something too small, but now that she wore it two thoughts dominated. One was how much it emphasised her additional rows of nipples when she arched 'just so'; and the other was that by wearing something small, she'd be prepared if...
... Well she'd just be prepared, that's what.
Head down, hunched forward to hide her chest and grinning to herself, Lisa whipped the door open, ducked under her elder sister's annoyed swat, and dashed down the hallway cackling, "All yours you old haaaaag!"
--------
Lisa recieved more than a few second glances and funny looks on her way to class. She did her best to be unobtrusive and hunched over to make sure her chest wasn't showing to anyone. She avoided all contact with people on the way in, keeping her head down and books clutched and pressed tightly to her chest. A few people did double takes and stopped what they were doing to stare, puzzled at her.
By the time she got her desk she could feel all rows of her nipples had hardened against her clutched books. Something about the looks she got reminded her of her dream, and she spent most of her first class day-dreaming about it. She could get the images out not her head. People staring and pointing at her naked and changed body. At first she was petrified, like in the dream, that someone would see her and call her out for her mutated body. She continued to shrink back into herself at first, the tight fabric of her too-small tee stretching and rubbing as she twisted. This continued for some time. First period, second period; then, as Lisa sat for second period she felt the tee pull loose from her jeans.
She straightened in panic and "eeped" as the fabric rolled up and she felt cooler air on the second from bottom row of nipples. She glanced down and could see the little pink nubbins poking out proudly. Her heart hammered and a rush of blood went in two dierctions. The first to her head, making her gasp and panic. The other went down, deep into her core as all the images of the later part of her dream flooded her mind. The rush of exhibitionism, of showing off her mutated rat body.
Red faced and trembling Lisa grabbed the offending tee and shoved it back into the waistband of her jeans. The damage was done, however. No more images of embarrassment plagued her now, just those of her twisted ratty form showing off in front of the entire congregation.
Her toes curled in her shoes as she got a vision of her nails growing, hardening, becoming claws. She splayed her toes, urging, willing, almost begging them to lengthen into paws. Rock hard teats begged to be freed. Her tongue kept flicking the backside of her longer incisor teeth, wishing she could use them to gnaw something. In an attempt at distraction, she grabbed a pencil, and, putting into her mouth, began to gnaw.
Immediately, relief rushed through her and she was able to relax. Something about the repetitiveness of it went to her core, and sated all of her other urges. It was almost a meditative experience. So, in fear of what she would otherwise feel, it was that Lisa found herself chewing through two pencils during that class alone, having started a third before the bell finally rang.
Lisa jumped and rushed from her seat, running to the school's stationary commissary between classes, buying a box of wooden pencils for fear she would run out of them, and revert to feeling as weird as she did at the start of the lessons.

[Hey Lis, wanna call over after school? Mom's away again working shift until 2 in the morning. Wanna see how ur doing.]
Hunched over, standing outside his house, Lisa looked down at the message. Eric was the only other person in the world who knew what had happened to her. Hell he and that stupid computer were the main reason it had. Though she didn't blame him, she loved him dearly, and right now as she stood there, waiting for him to open the door, she needed him too.
As the door opened and he sheepishly smiled at her, she stood up straight; almost the first time that day, new nipples standing and pressing against her thin tee.
His eyes swept up and down as she smiled back at him and stepped forward, leaning in and standing on her tippy-toes to kiss him, so great was the height difference between them now. As her lips met his, she felt him slide slightly up and graze the underside of her upturned nose. It made her shiver at the sensation
"Hey babe, how you feelin'?" Eric asked, as Lisa closed the gap and pressed her body fully against his. Soft and warm, he could feel her thicker thighs envelop his leg were they pressed. "I had some more looks on the chronivac, but no joy really, same as last night. So sorry again that this happened."
"Umm.." she fingered the cloth of his tee. "Felt kinda weird today." Her tongue involuntarily licked her buck teeth.
"Yeah? Weird how?" He asked. She pulled her head back to look up at him sheepishly. "I um... Spent a lot of the day chewing on pencils... I think I may have a new habit." This made her giggle; and somehow, it broke the tension. Both of them had a good laugh about it as they broke apart, and entered the house.
Taking the lead, Lisa went ahead of Eric and ascended the stairs to his bedroom. She felt his eyes on her wider hips so she happily milked swinging them in his face as she went.
Eric, for his part happily enjoyed the show as his altered girlfriend swayed in front of him. Reaching the bedroom he paused as Lisa turned to face him.
"I've also been very, very horny today. Think we could..." She didn't have to finish her sentence as Eric nodded enthusiastically. She was no doubt in a vulnerable position at the moment, and he was going to do everything to make her feel better.
"Cool." she said and padded back. First she kicked off her shoes and socks, uncurling her longer toes sighing in relief. Then hooking thumbs into the waistband of her tracksuit, she pulled and strained it down over her much widened hips, revealing pale soft white skin and a cream panty straining at the seams.
"I definitely need to buy new clothes. My shoes are too small, my pants leg too long and waists too small. And my tees. Well they're way too big." She grinned, buck teeth on full display and nose crinkling up. Almost by habit now she was hunched forward, holding her hands.
Eric's eyebrow went up, and Lisa noticed the look. Looking down at herself. Catching the ratty stance she stood up straight again. This time she smiled. "Kinda been doing that too." Without any more ceremony she pulled the massive tee over her head revealing her breasts and rows upon rows of pointy nipples.
"Don't think I need bras anymore either. Don't think in general anyone sells clothes in my dimensions." With only the under strain cloth of her panties hiding any modesty, the short, thicc, mutated girl radiated heat and want.
"Say... Do you think I look like a rat?" Lisa asked. Eric, unsure of her tone answered with a hesitant, "You look like you Lisa, you're beautiful." The slight wince in her eyes confused him then.
"I know I'm me. But do me, I, Lisa, look like a rat?" She churred. Now a little on the backfoot he stammered a quick. "Of course you don't, it's barely noticeable."
"Liar" Lisa stated, tone insistent. "I'm a mutant" She said, tone turning sultry, confusing Eric.
"You're beautiful" Eric retorted.
"I'm disgusting..." Lisa countered in a moan. Eric was incredibly confused, Lisa looked incredibly turned on, but what she was saying had him worried she was spiralling down a worrisome path.
"You're not disgusting. You're beautiful" He grabbed her arms, fingers sinking into soft flesh.
"Call me a disguising rat" She begged, chest arching against his touch.
"Huh!?" Eric was caught off guard again.
Her tone was pleading, "Please, call me a disgusting smelly rat"
"But you're..." Eric started.
"Please!" Lisa cut in again. "Please do it", Eric looked her up and down, she was weak at the knees now, barely standing, he could see a dark front to her panties. She was definitely turned on. Against his better judgement Eric slowly answered.
"You're a disgusting rat". Lisa's moan was loud and long as she sank to her knees, hissing "Yesss..."
Confused but turned on by Lisa's state, Eric tried again. "Ah, um, dirty rat!"
"Yes I am!" Lisa enthusiastically nodded, scuffling back and tearing the sodden panties from her. Scrabbling onto the bed she lay on her back pulling her legs up and spreading her soft thighs to expose her pulsing asshole and engorged glistening vagina.
"I'm a smelly, dirty, disguising rat." She grinned.
Now getting into it, and getting what Lisa was at, Eric freed himself of his clothes and jumped onto the bed, sending Lisa into a squealing fit.
As he stoked her face and lined himself up with her warm slit ready to envelop him he whispered in her ear. "Some new kink you have my smelly, disgusting, dirty, rat girlfriend".
Squeaking in happiness and need Lisa intertwined her legs behind him and pulled him into her short, curvy, pale body.
"Fuuuuuccckkk.... You keep calling me that and there's no way you'll be able to get rid of me." She laughed, humping and squeezing him
"So you're okay with your new body then!?" Eric half stated.
"Being a disgusting rat-girl has it's advantages" She grinned, "Now fuck me... Stud"
And fuck her he did, until drenched in sweat, both collapsing in a heap on top of each other.
