It took Eric a full week to fully notice the slight personality shift in his girlfriend. At first he thought she was still a bit melancholy from the eventful night, but quickly he noticed it wasn't quite that.
It was more like, an internal turmoil and skittishness within her was gone, and she seemed more, resigned, or something.
She skulked her way through school, a mild grin on her face whenever anyone referred to her as a rat.She was quite open with her gnawing now too, freely chewing chronivac created wooden sticks in front of anyone, parents, teachers, peers.
She ratcheted up their sexual play on the school grounds too. There was barely a lunch or break where she didn't pull him aside somewhere for a grope or a quicky. Eric had been reduced to up his stamina and recovery via the Chronivac a little just to keep up. The fact that she didn't have the Chronivac boost for her libido was astounding.
The most noteworthy event was when she shocked most of the school populace another week after that for swimming lessons, emerging from the dressing rooms not wearing the usual one-piece, but a two piece swim suit.
Not only did this leave all of her extra nipples on full show for the entire congregation, but it also made abundantly clear to everyone that Smelly Rat was not shaving anything anymore. All of her nipples were completely rock hard and puffed up, while her bush stuck out of the panty on all three sides. Guys gawked at the rows of pointy nipples never seen in person before, while girls, shocked, immediately began to gossip and point.
Comments of, "What a slut", "look at the state of her", "oh my god, she's such a freak" and, "she's so hairy", were immediately heard coming from the group.
Trying to suppress her spreading grin, the shaky mutant girl got as far as getting into the water before the teacher's T.A. was dispatched to cover her up and drag her out. Wrapped in a robe and hair still dripping it didn't take long before she was in the principal's office with her parents on the phone.
Of course, with the Chronivac having normalised her change, the school was just concerned with her exposure. To their credit, her parents just agreed with her argument that she just wore the same uniform as all the other girls, and that punishing her was discrimination. The argument raged for some time but eventually the school relented.
In victorious protest, Smelly Rat dropped the towel and strode all the way back through school grounds in her swim suit to retrieve her actual clothes, bare feet slapping against the floor with every step. Had her suit not already been wet it would have shown a damp spot in her crotch from excitement.
From that day forth, every swimming PE class she wore the two piece relishing the stir it caused.
In the bedroom, their wordplay evolved at her slow but steady request, as did her want to be dominated and humiliated.
It wasn't unusual for Smelly Rat to find herself crouching on the ground, being blasted in the face by Eric, while he called her things like, "Disgusting Smelly Rat, look how she gobbles cum, bet you wish it was rat cum. You gross animal."
Eric would have felt bad shouting the like at her a few weeks ago, but her face was always one of resigned acceptance of what she asked him to say, and the puddles of grool left behind proved she very much got off on it.
Some month after starting to use it in the bedroom Eric, wanting to expand the boat, and it co-inciding with their 3 year anniversary, decided to do something special, inspired to do so by her request to, "make our anniversary a memorable day", and her insistence she felt like a good, "kink session"
Smelly Rat entered the bedroom that night and gasped. Eric stood in the middle of the room, holding a collar and a leash in his hands.
"Hello you Disgusting creature... time to strip!" He demanded. "Rat's don't wear clothes." He added.
Frantically Smelly Rat pulled the clothes from her hunched body, then stood grinning wickedly back at him.
"Good... now kneel you animal. Rats get leashes." He continued.
Moving almost so fast she tripped, Smelly Rat got on her knees, trembling in anticipation as Eric closed the distance, and wrapped the collar around her neck. As he did, Smelly Rat, rubbing her nipples, gave a gasp and a twitch of pleasure.
"I see how much you love showing off your filthy ratty body. Showing off all your changes. Well... tonight we're going to have fun with that my Smelly Rat." Eric chuckled.
Smelly Rat trembled and with an excited voice asked, "W-what are you planning?"
With a wicked look, Eric responded, "Why, you're going to show yourself off fully to everyone." He revealed.
Smelly Rat gasped, "But, the police!?".
Eric waived his hands, "Don't worry, I've worked a few Chronivac filters in. No one will think to report you, physically interact with us, and once you leave their sights they'll forget what happened".
Smelly Rat's mouth closed in surprise, as he continued, "but any reaction they have while you're there will be completely genuine."
Bringing forward a leash he clipped it with a 'click' to Smelly Rat's collar. She leaned forward with a deep, "Oooooooohhhmmmmm". Eric paused, "Did you just cum?" He asked. To which his ratty girlfriend feebly nodded, a grin spreading widely across her face.

It did not take long into their walk for Smelly Rat to begin enjoying herself immensely. People stopped and stared. People pointed. People gossiped and whispered. People jeered and heckled. She loved it all. It was like her dreams coming to life.
"What the fuck is that!? Why does she look so freaky? Is this like performance art or something?" One person called. Eric was about to respond when Smelly Rat, hyped up on adrenaline, finally found her voice.
"I'm not art, I'm a rat mutant who loves being naked. Do you like my body!?" She asked, hands rubbing all over her tit covered chest.
"Fuck. What a disgusting freak", the man called out and hurried away from them.
Eric watched as Smelly Rat's hand trailed down into her bush and she began to slowly circle her clit. Making walking a very very slow process.
"Hey, nice ass-eeeaugh. The fuck is up with your body!?" Another young man exclaimed as her rounded them.
Smelly Rat grinned, "Well, I used magic to shrink down really small, then fucked a rat quite a lot. Absorbed all of his ratty cum, and turned part rat myself." Her tone was proud.
"You fucked a rat and are turning into one!? That's the most messed up thing I've ever seen. Who's he then?" The man pointed at Eric.
"Oh him, he's my owner and master" she grinned. In a panicked hurry the man scampered off. She turned to Eric and smiled. "This is fun... Master."
The next person walking their way with a shocked look, Smelly Rat took the initiative and greeted them. "Hi, I'm Smelly Rat, I look like this because I fucked my master's pet rat, don't you think I just look weird?". This immediately sent the woman fleeing with a "The fuck?!? Freak mutant weirdos."
The succession of next interaction all went similarly, though Eric noted they seemed to get more intense.
"Hi, I'm Smelly Rat, I'm a mutant rat-girl, I fucked a rat and turned into this. Look at all my nipples, aren't they disgusting!?"
"Hi, I'm a mutant rat girl. I fucked a rat, absorbed his cum and grew all these rat parts, I love them. You think I'm a disgusting animal right!?"
"Hi, Smelly Rat, that's my real name, because I love rat cum and it did this to me! Can you imagine, fucking a rat just to look this good. I'm such a filthy mutant."
"Don't look away, look at me. Look at these filthy nipples, look at my rat face, look how hairy I am. I'm a filthy, disgusting Rat mutant. I love rat cum, and I fucked my master's rat just to look this good! He was unreal! Hnnnggh... fuck yes..."
Smelly Rat was frantic at this stage, she was openly pawing her many nipples and fingering herself awkwardly while waddling around. Eric, holding the other end of the leash was loving it. He could see that the depravity of the exhibitionism was playing into her most animalistic tendencies, and, with a mind always on the wonderful furry and transformative rat porn filling up his phone, he really really wanted to egg her on.
So with no one around right then he joined in.
"Look at you, you gross rat creature. Out here with actual humans, talking about fucking rats and mutating."
Smelly Rat turned, with a surprised look on her face, "Eric!?" She gasped. Reading her mutated face he could tell she was flipping between shocked, and incredibly horny.
"You just can't help it! Just a filthy animal, dreaming of fucking my rat. You'd love to be shrunk again, wouldn't you!?" It was phrased as dirty talk, but Eric did put the slightest emphasis on it. "I could shrink you down, scrub his cum clean, and have him fuck you all night long, and you'd love that. I wouldn't even have to change your mind filters now."
"Eric... nnnngghh" she was panicking now, eyes wide and terrified, but unable to stop masturbating. He was pressing her buttons hard now, knowing it was pressing the issue for her she'd been unwilling to talk about or acknowledge out loud. Her eyes were pleading, but he could see she was torn between pleading him to stop, and wishing to egg him to go on.
"Maybe I won't even scrub the rat cum, and you can grow a nice long tail."
That was all it took to send Smelly Rat over the edge. Face scrunched up and furrowed, stomach twitching, she moaned into a long orgasm. Fingers buried in, she drew a deep breath and on the second moan, slumped to the lawn under her feet, face hitting the dewy grass.
It took her some time to come around to being able to take in her surroundings again. The grass, an alder tree. Pavement, a red parked car. Yellow door on a stone house, that Eric is knocking in Wait...
"My house!? Eric! No!" She hoarsely exclaimed as the door swung open. Smelly Rat, too weak to get up yet turned her head, hoping her dad couldn't see her and end up punishing her. She'd never be let out again. Then she remembered the change for people, they wouldn't remember this. In her head, she raged at what she would say or admit to her parents when suddenly her father spoke.
"Ah Eric, thank you for bringing Smelly Rat for a walk. She does so get cooped up and restless in the house otherwise." He smiled a friendly smile at Eric, and turned to his daughter, gaze patient.
"Come on girl. Time to go inside, you've had your walk now. Time for food." He beckoned sternly.
Puzzled, but slowly understanding Eric had played with their reactions too, she slowly picked herself up, and stumbled over on shaky legs. When she reached her father he pulled her closer and unclipped the leash from the collar. "I saw you came on the lawn again Smelly Rat." He said with a disapproving tone. "I know you can't help it. But I do ask if you could try to wait and do it indoors!"
She 'eeped and scooted past her towering father shooting a look of excitement back at Eric.
"Thanks again son. You're so good to our little Rat. See you tomorrow." He closed the door.
"Right Smelly. Dinner's waiting..." he pointed at the kitchen
