Why did he smell burning?

Izuku groaned, slowly coming to the realization that something was off. Sometimes he'd smell the neighbors cooking, so maybe they were just having a bad start to their day. That sounded about right. But, wait, that wasn't what was wrong. Normally he didn't wake up all on his own. His cat Midnight would be there on his chest, purring loudly and complaining that she hadn't been fed yet.

Well, not really, she was simply a loving—if a bit odd—cat that he had saved a few months ago. He never really thought of himself as a cat person but he adored her companionship.

Izuku sat up in his large bed, enjoying waking up naturally for once. It really wasn't something he thought about when he decided to adopt Midnight, but here he was. Whatever had kept her from waking him up, he should find a way to repeat it. Izuku scratched his chest, and then stopped.

Didn't he have a shirt on last night? And why did his neck feel a bit moist? Did he forget to dress a wound or something? No blood on his bed or pillow.

Standing up he headed over to the mirror that hung on his closet door and inspected his neck, a string of red marks on his neck and chest. Strange? Wait, those were where Midnight liked to lick him, was he becoming allergic to his cat? That sounded terrible. There was no way he could live without Midnight.

He should check with a doctor soon, still he didn't feel anything about those areas, they were even sore or anything.

Rubbing his neck Izuku glanced up and down as his currently shirtless self. Because of his life as a hero and the nature of One for All, he was really fit, especially for a 25 year old. He didn't think he was that bad looking, though, he did hear people saying that he was plain, or that he had some kind of a baby face. "So, why don't I have a girlfriend?"

He sighed, and shrugged to himself in the mirror. He knew the answer, because he was a work-aholic that was still socially awkward and reeling from the break up he had when he was 16.

Which was getting pretty close to being ten years ago.

Wow, maybe he should try to move on.

Going on a date or something did sound fun.

Maybe, he should download a dating app. Or see if Mei figured out she was a human and could make real babies, though last he checked on her he was fairly certain that she was trying to turn herself into a robot. Mei was on a monitored list. Then again, maybe he shouldn't go after Mei.

Was Melissa single?

A clang came from the kitchen and Izuku blinked. That must be Midnight. Did she decide to cut out the middleman and just started feeding herself?

Considering how she could use the toilet, open doors, turn the T.V. on, among other things he wouldn't put it past her. Maybe she was like Nezu, only less super smart and just kind of smart, she sure did chatter a lot though. Was there a test to see if his cat had a quirk? Was that a thing? If it happened with Nezu it could happen with anything.

Izuku walked out of his bedroom and was fully intent on heading to the bathroom first. Then he realized the smell of cooking, was stronger, and was accompanied by the sounds of cooking. Coming from his kitchen.

If it was a stranger, he was going to be concerned, if it was his cat he was going to take her to the nearest vet/doctor/scientist, because there was no way that a cat should be capable of cooking. Especially since it smelled like pancakes.

His hand went to his phone as he approached the kitchen but found it was missing, he must have left it on the charger.

"What are you—"

Ass.

Izuku's entire thought process was completely halted when he saw who was cooking in his kitchen. And it wasn't his cat, that might have actually been less surprising. Instead he saw a half naked woman wearing one of his shirts.

She turned to look at him, a battered covered spoon sticking out of her mouth as she smiled at him. Her blue eyes felt so familiar, like he had seen them a hundred times over. With her wild dark purple hair that extended past her waist, and pleasant smile she was a real looker. Her legs were long, pale, and there was a lot of thigh being shown off, thanks to her bushy black tail pushing up his shirt so that all of her ass was exposed.

And what an ass it was. If she told him that her ass was her quirk, he'd understand.

But more importantly.

"Who are—"

"Meowning myaster!" The dark hair woman purred. "It's good to see you awake! I decided to let you sleep in this morning and that I'd cook food for both of us!"

She gestured towards the meal she was cooking and smiled even brighter at him, her blue eyes shining into his soul like a glimpse of heaven, though the way she wiggle her hips kept him grounded. Inside his shirt he could tell that something large was swaying on her chest. "Oh my, I should have known you'd be more interested in me ~ Nya!"

The one placed down the spatula and wiggled her hips again, raising her arms high above her head Izuku saw two important details he had missed early. The black cat ears that were strangely familiar on the top of the woman's head, and the collar with a bell on it around her neck. A very familiar collar.

"Well Myaster~" She purred, running her hands along the contours of her body. "What do you think of my new form?"

"I uhh, who, what?" This was bad. He had a weakness towards incredibly forward women that left him paralyzed. And wearing his shirt—and nothing but—was about as forward as it could get.

"Hmm, perhaps, the shirt is in the way," She pulled on the collar and glanced down at her breasts. Her pout was adorable. After a moment her face lit up. "Oh! I know, I'll do that meme you enjoyed so much, let's see it should be like this?"

She reached behind and grabbed onto the slack of his shirt, pulling it tight so that it hugged her body tight, exposing not only her outrageous curves, but her crotch as well. Her pubes were a lighter purple, and she was easily the sexiest woman he had seen anywhere near that level of nakedness.

"Nya~ I can tell that you like it, Master." She purred walking towards him. "But, we should probably wait until after breakfast! Nya! My first time eating as a human and my first time having sex? That's going to be a lot of fun."

"Sex?" Izuku shrieked, his voice cracking a bit. "Wait, I don't even know who you are? What are you doing here? Where's Midn...ight…" Izuku blinked. Blue eyes. Midnight's blue eyes. Cat ears, Midnight's cat ears. Fluffy tail. Midnight's fluffy tail. Collar with a bell. Midnight's collar. "Wait, are you Midnight?"

"Correct!" She jumped exposing herself to him once again, once she landed she pounced forward, jumping into his arms and wrapping her arms around his neck. She pressed her face into his neck and gave a light soft kiss. Oh. Those marks were hickies. "That took you longer than I thought, Master, but don't worry, I'm going to make sure to take care of you from now on! You deserve it!"

He could feel her breasts press up against his chest, his thin nightshirt might as well not even be there with how much he could feel, her warmth, her suppleness, her heft.

"Huh? But, wait, how are you human?"

"It's my quirk!"

He knew it. No cat used the toilet like that.

"So you're a human that can turn into a cat?"

"No, I'm a cat that can turn into a human Nya~" She nuzzled him and then stopped, placing both hands on his shoulders and looking him in the eyes. "Oh, and my name is Nemuri."

All things considered this was only about the third most confusing morning he'd ever had. The first being when One for All decided to talk to him, the second being waking up next to a naked Mei with a tag on his ear.

But still all things considered. "Huh?"

AN: I wanted to write a cat girl. And Nemuri...
