To some cats, catnip was the only drug that mattered. The not-so-innocent plant incited raw emotion, all worried vanishing as felines let themselves bask in their carefree days.

Well, with all due respect to catnip, Adrien had a different drug in mind that was far more mind-numbing and addictive.

The way Marinette threw back her head and exposed the pale skin of her neck to him, allowing him to press his mouth over it with hot and moist kisses - that was something worth pushing a little plant away.

Her fingers gripped his blonde locks as her free hand ran under his shirt, feeling the flaming hot skin of his back.

She was his everything, from the way her eyes her lit up when she got excited; from the way she'd untie her ponytails and tease him with not only her little red ribbons but her long raven hair; from the way she would hold him and not say a word when she knew he simply needed the comfort of company.

Marinette Dupain-Cheng was the most wondrous drug he had ever been exposed to, and he knew he was doomed to be addicted to her for all of time.

Adrien grinned against her throat as he pressed his girlfriend further against the cushion of her chaise, reveling in the way her pretty pink lips parted as she arched her back, seeking his touch.

"Eager, Princess?"

She let out a soft groan.

"Shut up. Keep kissing me, chaton."

"As my Lady commands."

OoOoO

Their first kiss was when they were fifteen though Marinette refused to count it.

"It was to a break a curse," she wailed whenever he got cocky and brought it up. "You don't even remember it!"

"Doesn't matter; my Princess saved me from a wicked, wicked curse," he teased. "My hero."

Blushing, Marinette pushed him off of her chaise and pointedly ignored him as he laughed on the carpet.

OoOoO

Their second kiss had been accidental. Well, it wasn't an accident, per say, but getting carried away most certainly was…

"I-I'm sorry?" Marinette stuttered, eyes blown wide as she looked up at the model.

He gave her a sheepish smile, rubbing the back of her neck.

"I mean...it's a shame we didn't get to finish the scene. Mylene and Ivan are great," he said quickly, despite the couple not being around. "But well...I thought we could finish the scene, just to see how it would have gone?"

The Scene.

As in, the scene where her character kissed his; where Marinette was supposed to kiss Adrien.

An inhumane noise garbled its way out of her throat as she continued to gape at him. The seconds ticked by, and he began to shift a bit awkwardly.

"Unless, of course, that's too weird…." Adrien said finally, avoiding her gaze. "I just never really did something like this before…"

"You're in front of the camera all the time," blurted Marinette.

He chuckled, and boy, if his laugh wasn't the most beautiful thing she had ever heard, she didn't know what was.

"Well...that's true, but I mean...I'm not working with my friends then," he said quietly, almost shyly.

Well, how could she refuse him after that explanation?

Marinette smiled kindly, pushing away her very panicked emotions for the moment. It was sort of a new experience for Adrien, and she was determined to make him experience as much normalcy as he wanted.

Taking a deep breath, she summoned a bit of her Ladybug courage.

"Well, then, s-shall we?"

Adrien's bright smile made her temporarily forget the butterflies fluttering in the pit of her belly.

"And...action," he said softly before he got in character. "We need to get you out of here, Agent Smith. It's too dangerous; you could get hurt."

"I'm not scared of that monster, Officer Jones," she said, far more confidently than she did during the actual rehearsal.

She nibbled on her bottom lip for a moment before she stepped forward, tilting her chin up as he leaned down. Her hands gently placed themselves on his chest, her eyes fluttering shut.

When their lips just barely brushed against each other, they stopped, as if someone - namely Chloe - was going to burst in and interrupt them again, but nothing of the kind happened, and Marinette leaned forward to press her mouth against his.

She gasped when his hands gripped her hands a little tighter, a subconscious action most likely, but it didn't hurt.

Sparks. There were definitely sparks.

It was so unbearably cliche that not even Marinette, a hopeless romantic, believed kisses could have that sort of effect on someone, but she was so very wrong.

It had just been a gentle brush of their lips, so how did it instantly change into them devouring each other, drinking each other in like a dying man in the desert drank water?

How did Marinette end up sitting on the desk, legs wrapped around his waist as he rocked his hips against hers?

How could she explain the hand skimming the back of skin under her shirt, stopping short just under the clasp of her bra?
The hand bunching the material of his shirt to pull him closer, closer to her?

The soft gasps that left her lips when his ghosted over the nape of her neck?

The ribbons falling to the floor as he let his fingers comb through her now loose raven hair?

If it wasn't the fact that they relied on oxygen to breathe, she was sure they would have stayed like that for the rest of the day. Possibly forever.

Panting, Adrien pulled away from her, his cheeks flushed, and his eyes darkened with desire as he looked her up and down, looking uncharacteristically smug as he took in her disheveled appearance. He had done that, and she doubted either of them would forget anytime soon.

Marinette's hands shook as she removed them from his person; likewise, his hands slowly left the warmth of her back, though his fingers did graze longingly over her hips, making her shiver.

"And...scene," he murmured.

"Scene…" She agreed, closing her eyes.

It was a scene. Just a scene.

OoOoO

There were also extended, deleted scenes.

Like when Marinette wore that Chat Noir sweater with knee socks to school, and Adrien had pulled her into the nearest storage closet, pressing her body against the door and capturing her lips before she could fully comprehend what he was doing.

They didn't talk about what they did or how it affected their friendship. In fact, there was little talking at all when they were like this.

Marinette was panting in his ear as he slid his hands up her thighs, over those damn socks, and stroked the flesh under her ass, which was unfortunately covered by her shorts. His face was buried in the crook of her neck as he placed soft kisses on the areas he could reach.

"A-Adrien…"

By god, if his name spilling from her lips in that breathless whisper wasn't the most erotic thing he had ever experienced, he didn't know what was.

"Quiet, Princess," he purred, making her shiver as she felt the vibrations from his mouth. "We wouldn't want anyone to catch us, would we?"

Neither of them registered the nickname as Marinette suddenly moaned at the thought of being caught in this position; it would be disastrous, for sure, but the idea of someone catching them so flustered and enamored with each other certainly did something to her.

Adrien couldn't get enough of her and he took the chance to place his hands over her bottom, making her gasp as he lifted her up, still pressing her back against the door. Her legs - such nice, nice legs - wrapped around his waist and her nails dug into his shoulders as he crashed his mouth against hers.

She was rocking her hips against him and he groaned, pressing himself harder against her. She was going to be the death of him, and he her.

However, all things had to come to an end and it was the screams outside the closet that forced them to pull apart. An akuma, they could tell, from the crashing and shouting; the demand for Ladybug and Chat Noir was a pretty big hint too.

Marinette struggled to catch her breath even as she absently continued to rock against him.

"We should...go," she managed to say. "Out of danger."

Adrien was on the verge of suggesting they stay in that closet and ignore the danger - what were the chances of them getting hurt in there anyways - when he felt her shiver from the coolness of his ring that brushed against her skin. Right, right, his ring.

He was a superhero; a superhero in demand, and his Lady was most likely waiting for him.

Sighing, Adrien nuzzled his face against her shoulder for a few seconds before he pulled away, gently placing his classmate back on the floor.

Hawkmoth had shitty timing.

OoOoO

They weren't sure if they were dating or not - no one but them knew of their secret rendezvousing - but both Adrien and Marinette figured what they had was something close to that.

Why else would Sabine and Tom so easily greet the boy as he followed their daughter up to her bedroom after school? And have snacks ready for them?

He was over at their house almost every day, and if he didn't have so many appointments, he'd be there every single second he could.

"Did I mention I love your parents?" He asked, sighing in content as he broke off a piece of a croissant and tossed the buttery treat into his mouth.

Marinette looked up from her sketchbook, smiling at how relaxed he looked from her perspective on the chaise.

"Only every time you come here; they love you too, you know," she said. "Can't blame them either. You're quite the catch, handsome boy."

Adrien flushed at her words and she smirked.

That was a benefit of their little arrangement; not only did she get to continuously make out with the love of her life, but she managed to be his friend too. A friend she didn't stutter around anymore, and a friend who could make him as flustered as he made her.

("That's called a fucking relationship," she could practically hear Alya screaming at her.)

"You're not bad yourself, Princess," said Adrien after a pause, grinning at her as he gave her a look that she knew by heart.

Marinette rolled her eyes and tucked her sketchbook under her chaise before she curled her finger at him.

In a flash, Adrien was hovering over her and she laughed as she leaned back against the cushion, his lips ghosting over hers.

"Your eyes are so blue," he whispered. "So beautiful."

Marinette hummed as her fingers ran through his golden hair, giggling at the soft purr that came from him as a result.

"What a silly kitty," she said, leaning up and capturing his lips.

Before they could get into it, Adrien's phone rang and they both groaned. He reached into his back pocket and glanced at the caller ID.

"It's Nathalie," he said apologetically as he pulled away. "I'll be back in five."

He got off of her, albeit reluctantly, and Marinette sighed as she sat up, watching him go downstairs to answer the call.

"In five, you'll have to go," she said, getting off the chaise and straightening her clothes.

Looking at his books sprawled out on her rug, she decided she might as well help pack up his things.

Bending down, Marinette carefully picked up each of his notebooks and pens, gathering them up in her arms before she went over to her computer.

Setting the books on the desk, she opened up Adrien's bag.

She blinked.

A pair of luminescent green eyes blinked back.

Marinette from two months ago would have screamed and might have strangled the little cat creature staring at her, denying whatever implications that came with this discovery.

Marinette at that moment merely bit the inside of her cheek and wondered how she didn't see it before.

She reached into the bag and gently picked up the kwami, who was trying his best to act like a stuffed toy; at least it would have made sense if he meowed, unlike when Tikki did it nearly two and a half years ago.

"So…" Marinette smiled. "You're Chat's kwami. You're much cuter than he described you as being."

The kwami in question regarded her for a few seconds before he guffawed.

"Oh, man; Fuu can really pick 'em. Got any cheese, Ladybug?"

Marinette gave him an odd look but didn't comment as she turned around, just as Adrien's head popped through her trap door.

Green met blue; he took in the sight of his kwami sitting comfortably in his girlfriend's (?) palm.

And then he panicked, scrambling to get his full body in the room as he struggled to find a reasonable explanation.

Marinette laughed.

"Calm down, chaton. The secret was bound to come out sooner or later, right?"

OoOoO

"Say, Mari," said Adrien, staring up at the ceiling of his girlfriend's room as she snuggled up against his chest. Plagg and Tikki were curled up nearby in the little makeshift bed Marinette had made for them a few weeks back.

She let out a sleepy, "what" and blinked up at him.

The model smiled softly as he ran a hand through her hair.

"I love you."

Marinette smiled and leaned up to kiss him, softly and lovingly whispering her own "I love you" into his ear.

He got high off of her kisses, and they were the greatest drug he had ever been introduced to, but her very presence was enough to soothe him and leave him permanently content.

She was his other half, and no drug in the world - not even catnip - could compete with that.
