She doesn't notice at first.

Her focus was on the screen of her yo-yo as he landed on the balcony beside her. The familiar black blur of his tail was barely noticed as it swayed from side to side as he made his way towards her, pressing his side against hers as he peered over her shoulder.

"What's the plan today, Bugaboo?" he asked, extending his staff to act like a cane.

Ladybug hummed, fingers flicking on the screen to zoom in on a map of the streets of Paris. "Well, Hawkmoth hasn't chosen a target at all this week, so I expect he will try to find a victim soon. But until then, we could always patrol along the Seine until we reach the Eiffel Tower."

Chat Noir nodded in agreement. "Sounds good to me. We could hang out there, maybe talk to a few civilians, brighten their day. I'll have to head home early, though, Father scheduled my Chinese lessons earlier than usual."

She sighed at that, closing the yo-yo so that the screen was hidden. "You know you could always practice with my maman, she doesn't mind teaching you."

"Oh, I know!" he said as he raised a hand to rub the back of his neck. "But you know how Father is, he'd rather have a professional teach me than my girlfriend's mom."

Ladybug scoffed at that, eyes finally moving to him as whatever response she was going to say died in her throat. On top of his head was his suit's black ears, but with the noticeable difference that they were fuzzy . Gone were the leather ears that she grew accustomed to. In their place was the unmistakable, honest to god, actual cat ears . A smile grew on his face as he realized she noticed the change, and he took as step back so she could see without craning her neck.

And look she did. His furry ears were in the same exact spot as his previous version's, but they seemed to move a lot more freely than the others did. The short, black fur shifted slightly in the breeze, and she was glad it was still daylight so that she could see that detail. The sound of a car starting nearby caused one of his ears to jerk in that direction, and dear lord was that cute. The only thing that would make it better is if he made is tail to be real as well and- yep, there it was. Instead of the belt that she had expected, a smooth furred tail curled to his side, the tip of it flicking back and forth as he watched her in amusement.

She stared at the tail, watching it move like an upside down pendulum. His chuckle was the thing that startled her out of her trance, eyes darting back to his face as he spoke.

"What's wrong, m'lady?" he purred, eyes darkened as he stared at her. "Cat got your tongue?"

She nearly dropped her yo-yo as he licked his lips before flashing her his teeth. And, fuck, were those fangs she saw? Legs a bit wobbly, she stood shakily as he ran his tongue over his newly elongated canines before he lightly bit his bottom lip, fang clear against his skin. And, god, didn't she wish it was her own skin he was biting into. Shivering slightly at the thought, she imagined him pressing up against her as he nuzzled her neck, fangs sliding across her neck and nipping her skin before finally sinking his teeth into her shoulder-

The akuma alert that sounded from her yo-yo and his staff jolted her from her thoughts, and she took a trembling breath. Duty calls. His ears went backward in displeasure, and he huffed before stepping back towards her and kissing her chastely on the lips.

"We'll talk about this later," he murmured, a clawed hand lightly cupping her chin.

She nodded, brow furrowing as he stepped back and the two briefly looked at their respective weapons for the akuma's location before leaping onto the next rooftop.

Pushing the new discovery from her mind, Ladybug's thoughts turned towards on how to find the akumatized object on Hawkmoth's latest victim. The familiar steps of locating it, calling her Lucky Charm, and figuring out how it would help to break the object cleared her mind, and she nearly forgot about Chat Noir's changes as they did their customary "Pound it!"

Nearly. His tail brushed against her leg, and she shivered slightly, wishing that she could feel how soft it was through her suit. He smiled softly at that, and leaned down to whisper in her ear. "I need to get going, but I'll come by later to chat about the changes I made, okay? Is ten good?" She made a confirmative noise, nodding. "Great, until then m'lady," he said, grabbing a hand to kiss as he bowed.

She laughed, using the same hand to lightly shove his head away. "Until then, Chaton." The two grinned at each other before heading their separate ways.

. . .

Marinette sighed, erasing her sketch again . That dumb cat and his stupid tail, stupid ears and stupid fangs. Tossing her sketchpad to the side, she groaned into her hands as she laid down on her bed. She had thought that making new designs would distract her until he came, but every time she tried to focus she kept on being drawn back to Chat Noir's new changes.

The gentle brush of her kwami's paw on her hand made her lower them to her chest as Tikki floated in front of her. "What's wrong, Marinette?"

" He's what's wrong!" the teenager cried out. "He… he had to go ahead and make his ears and tail like an actual cat's and now I can't stop thinking about it!"

"Is that all you were thinking about?" the kwami asked, eyes twinkling as Marinette sputtered and grew red.

"Tikki!" she admonished, fingers gripping onto her nightshirt. Her heart pounded as she realized that the kwami had felt her slight arousal earlier in the day.

"It's not like I haven't had a holder feel like that when transformed before," Tikki said, shrugging.

Marinette squeaked at that, eyes wide as the two heard a thump from above. Both pairs of eyes went up as the skylight window opened, shining green eyes peering down at them. Chat Noir blinked slowly at the two before he crawled into her room, shutting the window as he landed softly on her bed beside her.

"Hello, princess, Tikki," he purred as he sat down. "Plagg's gonna be occupied for a bit, but he'll join you later, Tikki." At that, he winked at the kwami, causing her to giggle knowingly.

"Of course," she chirped, hiding a smile behind her paw. "Send him down when he's free." Tikki sent a comforting smile to her chosen, quickly nuzzling her cheek before she flew down out of sight.

The two sat, or in Marinette's case laid, in silence for a few moments. Chat's ears twitched as he listened for any sound in the floors below, and Marinette wanted to pet them so badly.

So she did.

Her hand raised up and he pressed his head against it, purring when she scratched behind his ear like she did when it was just leather. Her fingers grazed the back of the furry ear, causing it to flick, as if it was trying to get rid of a pesky bug. Which honestly wasn't far from the truth, but she wasn't going to fly away. Oh, no. Her thumb came around to the front of his ear, and she lightly ran it and her pointer finger upwards. The ear was a bit cold on her skin, but she figured that was due to the night's cool air as he traveled from his mansion to her house.

"So how come they're real?" she asked, eyes quickly darting to the tail that was curled next to her leg.

She scratched behind his ear again, and he spoke through his purring, voice a bit distorted from it. "Hmm, so Plagg mentioned one day he can change the suit to what we truly want, and I asked about the animal traits. You know, since I can see in the dark and all. Apparently the transformation can give you as many traits as you want without becoming the actual animal. Figured you'd like it."

"I do," Marinette hummed, tugging on his hair. "Come here, kitty. My arm's getting tired."

Her legs spread a bit and he quickly crawled between them, his hips aligning with hers as he nuzzled into her neck as both of her hands petted his ears. His purrs grew louder, and she could actually feel the rumbling on her chest.

"Does it feel different from the leather ones?" she asked.

"Mhmm, I can actually feel it," he said, pressing a kiss to her jaw. "Can feel your hands are warm."

"Your tail?"

The tip of the mentioned body part was curled on top of her ankle, tickling her gently, and he shrugged. "About the same, I think. You can pet it if you want."

One hand released his ear, and she trailed her hand down his back to his tail. It was soft just like his ears, if not softer, and she couldn't help but think she preferred this version of it the most. Not that the regular belt tail wasn't useful, but she thought it would be preferable to have the actual cat tail when they were alone and not facing an akuma that wanted to take their miraculouses.

Suddenly remembering a few cat videos of some cats acting funny, she scratched her nails at the base of his tail where it met leather. Chat stiffened above her as he inhaled sharply. He nipped at her neck, reminding her that he had fangs now too, and growled.

"You don't wanna do that, Bug."

"Oh?" Marinette said, lifting a leg over his hip and using it to press him against her. His head jerked up and he stared at her, pupils blown. "What if I want to do that?"

He groaned as she proceeded to scratch the base of his tail again. The black tail quivered quickly under her touch, and his hands gripped her comforter, claws digging into the fabric. She laughed quietly at his reaction, and his eyes narrow as he rutted against her. Feeling him twitch through her pajamas and his suit, she shifts her hips up to grind against him, hand still scratching all the while.

Letting out a breathy, " Mari ," he left one of his hands to fist her comforter, holding his weight, as his other slowly trailed down her side. His claws ran across her shirt and pants as he grabbed the underside of her thigh, slightly pricking her through her clothing. Lifting it higher, he growled as he pressed against her hard . She bit back a moan, and the hand that's still on his ear feels it go backwards in concentration as he ground against her.

" Chat ," she whimpered, head pressing back against her pillow. Seeing the opportunity, he ducked his head down to kiss and lick at her neck. Her grip on his ear loosened and she buried her fingers in his hair. His fangs glided across her skin, and she shivered and whimpered when he nipped her neck.

His ears moved forward at the sound, and she felt his lips grow to a grin. The grip on her thigh increased as he pressed harder against her. "Oh, you like that? You like the fangs?" he growled into her ear, nipping around her earring before pulling back to see her face. "I thought I saw you looking at them earlier. Were you imagining me biting you, marking you so everyone knows you're mine ?"

His tongue ran across his teeth again, mimicking his actions from earlier in the day, and Marinette freezes. Her gaze went unfocused as she remembered exactly what she was thinking about when she was Ladybug. Her core throbbed at the memory and she let out a gasp when Chat surged forward, kissing her deeply before whimpering a quiet, "don't stop," against her lips.

Realizing her hand stilled, she resumed scratching his tail and he purred appreciatively as he continued to thrust against her. It was faster than before, and she realized that he was close while he panted against her mouth. Detangling her fingers from his hair, she brought her hand down so both of her hands were scratching the base of his tail. He gasped, face burrowing into her shoulder as he moaned. She could feel his claws dig into her skin and hear it tearing her comforter as he frantically rutted against her.

Although she was nowhere near as close as he was, she dug her fingers into the fur of his tail and wrapped a hand around it and slightly tugged . A sharp pain on her shoulder made her cry out as he moaned into her skin, teeth buried into her shoulder as he came. He gave a few slow thrusts against her as he came down from his high, chasing the last bits of pleasure he could until he finally stilled against her, releasing his grip on her leg.

His jaw relaxed and he released his hold on her shoulder, licking at the slightly bleeding teeth marks. As his tongue lapped away the blood, his purring resumed in full force. Marinette hummed as 'groomed' her, hands leaving his tail to rest on his ass. Adrien always seemed to like grooming her after he came as Chat Noir, probably another thing that was influenced from his miraculous, but she didn't mind it too much. After he got it out of his system, she knew he would return the favor. Until then, she relaxed under his purring, giggling softly when he moved up her neck, licks slowly merging into feathery kisses that made her heart feel like it was going to burst out from her chest. He slowly reached her face, pressing a kiss to her lips before uttering, "claws in."

Plagg shot from his ring as her room flashed green, the dark kwami shaking his body as if it would rid him of the feelings Adrien experienced. He shot a dark look at his chosen, who was completely focused on his girlfriend underneath him, and rolled his eyes when Marinette's gaze moved to him. The girl wasn't done with the blond yet, and Plagg knew that. He zipped down out of sight, and the two could hear him complain to Tikki on how unfair it was that he was used in these situations more than she was.

Marinette snorted at that. The two kwamis liked to tease them about having sex, but she knew they didn't really care much about it themselves. They just wanted their holders to be happy.

Speaking of happy, she turned her attention back to the boy above her, lifting her head to softly kiss him. "Was this what you meant by I would like this? I think you got the better end of the deal," she quipped.

He chuckled, shifting slightly before making an uncomfortable face. "You say that as if I didn't just come in my suit. Seems like Plagg thought it would be funny not to clean this up."

Marinette laughed at that, hands pressing against his hips to get him to sit up. "You left a few pairs here last time your father was away on a trip. Get changed and finish what you started."

"Absolutely," he smiled, leaning down to press another kiss to her lips.

" Now , kitty," she warned, hand coming up to tickle under his chin. Although not as loud as it was when he was still transformed, Adrien purred at the touch before climbing off the bed. "I'm waiting."
