Author's Note: For those of you following this story. I've gone back and rewritten the first three chapters, giving more depth to the situation. I'd suggest you go back and start from the beginning but it's up to you as the plot remains the same. Cheers :)

Chapter Four

Chat Noir cocked his head as he watched his partner dash away like her backside was on fire. Shaking his masked head, the hero let out a sigh. "And like always, she runs away just when things are getting interesting." Snatching his baton from his back, Chat Noir suddenly broke into a smile. Ladybug was Marinette and he knew where Marinette lived.

Feeling delightfully smug with this revelation, Chat also realised that his partner hadn't headed directly home. That was to be expected, some time ago they'd agreed that it was best if they switched around their routes home so they weren't followed. It seemed that Ladybug had naturally fallen into their usual routine, as he knew the direction she'd gone in wasn't the fastest.

With this in mind, and a grin on his face, Chat Noir swiftly made his way to Marinette's balcony. As he arrived he immediately jumped down the open skylight and onto Marinette's bed. On all fours, he leant forward to see if she was in the room below. As he was doing so Ladybug dropped down, transforming back as she landed and stared at him in shock. "What are you doing here!?"

Chat Noir's attention was briefly diverted as a red kwami zipped by him. When Tikki was out of sight, he padded his way up the bed smirking as Marinette lost her balance and tumbled backward. Pleased with the opportunity, he crawled his way up her body and lowered himself chest to chest with her in a very feline fashion. "You ran, I chased. You know I live for the chase, right?"

Marinette stared up at him, her neck pulling back into the pillow. "B-but you weren't behind me."

He chuckled and touched the tip of his finger to her nose. "Now that I know who you are, I also know where you live. Besides I want to know why you ran away."

She swallowed. "Because you didn't use my real name."

Lifting his hands to prop up his chin, Chat Noir laced his fingers together and looked at her thoughtfully. "So, you took offence because I didn't call you Marinette. You do realise that up until about five minutes ago my every instinct is to call you by the name I know, which while in costume is Ladybug. Honestly, would your first impulse be to call me Adrien while wearing this?"

Ladybug gulped and blinked with wide eyes. "Well, um…"

"I didn't think so. But what I do find intensely interesting is that you kissed me as soon as you discovered who I am under this mask." He said tapping the black encircling his eyes. "What else intrigues me is what you did in that video, to know that it's Ladybug who wants to do unspeakable things to me is very, very enticing."

At that point Marinette lifted her hands to his shoulders and pushed herself up along her mattress and away, but she didn't get very far. Chat Noir stayed put as he continued to watch her. "So, you're only interested because I'm Ladybug?" She asked while worrying her lip.

"Oh no, I was already hot under the collar before that. Now though," he sucked in an unsteady breath, "I'm doing my best not to pounce on you."

"You are lying on me." She pointed out.

A flash of teeth showed in his smile. "Yes, I am. You seem nervous. Would you prefer me out of the mask?"

Marinette gave the faintest of nods and Chat Noir said the words that would release his transformation and he watched with delight as his lady's eyes grew hungry at his change of appearance. Adrien caught sight of Plagg in his peripheral vision but the kwami took one look at the situation and made himself scarce.

With his kwami gone, Adrien dropped his hands from his chin to rest them on either side of Marinette's shoulders and slid himself up so he was nose to nose with her. "Better?"

Unsteady hands cupped his face. "Do you want to kiss me like this? Out of costume I mean." She whispered nervously as her eyes trailed to his mouth.

"Yes," he all but growled as he dipped down to claim her lips. He intended to kiss her gently at first but her mouth hungry moved over his while her hands sunk into his hair, pulling him nearer. Adrien shifted one arm so he cradled her nape, the other reached for her waist as he tried not to squash her. Then her tongue brushed over his lips and he kissed her with increasing vigour.

Marinette's fingers strayed from his hair, down his shoulder, over his shirt and to his chest. Instinctively he arched up to give her more access and he groaned as his hips ground against hers unintentionally. The tension that had been building between them for years was unleashed, their pent-up emotions driving their need to explore each other into a frenzy. Adrien's tongue dipped into her mouth and she threw a leg over his, hooking her ankle around his knee to bring him closer.

The hem of her shirt lifted slightly and his thumb brushed the smooth skin of her hip. Marinette moaned his name into his mouth as she kissed him eagerly and he edged his hand upward to caress the bare skin on her side. Then her fingers found his peaked nipple and he broke the kiss to gaze down at her, breathing heavily. "You're driving me crazy."

She gave him a pleased smile as her chest heaved while she tried to catch her breath. Adrien's eyes were drawn by the movement and he groaned as he took in her nipples straining against her bra. Marinette took the opportunity to plunge her hands under his shirt, skimming them over the taunt skin of his belly and up to his pecs. "I can't believe you're Chat," she murmured as she gripped the inside of his shirt and pulled him back down.

Mischief sparked in his eyes. "Why is that?" he asked as he pressed a kiss below her ear and nibbled his away along her jaw.

"You act completely different," she uttered as she tightened her fingers on his torso.

Adrien ran his tongue from her chin to the hollow of her throat. "As Chat Noir I can express myself freely." He lifted his head to look at her. "I can be as passionate as I want. Is my shirt getting in your way?"

"A little," she admitted as she bit her bottom lip. Then she gasped as Adrien tugged his shirt over his head and dropped it on the bed.

"How's this?"

A hand hooked his nape and Marinette began exploring his chest with her mouth. His eyelids fluttered closed as she tongued her way around his pecs. Adrien's arms strained as he held himself over her, his own desire to pleasure her in return becoming urgent. He rolled onto his back, taking Marinette with him and switching positions. For a moment she was startled and he took the opportunity to nudge his hands under the hem of her shirt and slide them up her sides, his thumbs caressing her midriff and up to the undersides of her breasts as she leant forward to kiss him.

"We should stop," she murmured against his skin as she took his nipple into her mouth, completely contradicting her words.

Adrien cupped her breasts, his thumbs now stroking her peaks. "Are you sure?" he asked as he pulled the lace cups of her bra down for better access, her shirt still in place.

Marinette rocked against him. "We should but I don't want to."

"Neither do I," he told as he lunged forward to capture her mouth with his. Adrien kissed her frantically as he continued to stroked her breasts. Marinette shucked off her shirt, breaking their kiss briefly before she hungrily returned. She unclasped her bra, tossing it away as she pressed her bare chest to his, growling at the skin on skin contact.

Adrien grabbed her ass and ground himself against her, showing her just how much he wanted her. "We shouldn't go all the way," she gasped between kisses.

"I didn't think we'd get this far," Adrien chuckled as he nibbled his way along her shoulder.

She pushed him onto his back and rolled her eyes playfully. But before she could reply he zeroed in her chest, propping himself up on his elbows to take a mouthful of her breast and tonguing her nipple. Marinette clutched his head as she panted in arousal and he kissed his way to the other side. His hands caught her knees and he pressed his heels into the bed to undulate his body against hers. "You're killing me," she growled into his hair as his mouth continued to work magic on her tingling body.

"You have no idea how badly I want to get you naked right now."

"Actually, I think I do."

Marinette shuffled to sit back on his thighs, her fingers trailing down his abs and over the waist of his jeans to trace the bulging outline of his erection. Adrien's fingers dug into the sheets, as he sucked in a breath. "I get the impression you want me naked too."

"Whatever gave you that idea?" she smiled cheekily.

He caught her wrist. "As amazing as this is, we really shouldn't go any further. I don't want you to regret this tomorrow."

"Why would I regret this?"

Adrien released her wrist and drew his hand down to interlace their fingers. "Because you ran away from me when I didn't call you Marinette, plus we're in the heat of the moment. Believe me, I'd like nothing more than to continue but we've only just discovered that we like each other."

Marinette crossed her arms over her bare chest, suddenly self-conscious. She hated to admit he was right. Her current boldness was strength by his as well as the fact that he was Chat Noir and she had no problems expressing herself to her partner. Her footing with Adrien had always been uncertain. Even now as she looked at him with his heavily tousled hair and swollen lips from kissing her, she began to feel the nervous energy she usually had around her crush.

"I'm not rejecting you, Marinette." Adrien said as he noticed the worry in her eyes. He sat up and pulled her into a hug. "As I said to you in the mask, I love you. I couldn't be happier to find that my good friend is also my partner. To be honest I had wondered if you were Ladybug on and off."

Disbelief had her screwing up her nose. "You did?"

"Yeah, I did. I guess this is my unorthodox way of asking if you'll be my girlfriend."

Marinette blushed as she smiled shyly. "I'd love to."

"Fantastic," he grinned as he bopped her nose with his fingertip. "Now we better get dressed before I completely lose control and throw you down on the bed to have my way with you."

Things are moving faster than either of the superhero couple would have imagined. But what will the next day bring? Marinette always tends to overthink things.

Thanks for reading! Apologies for the massive gap between chapters.
