I didn't go full sin on this. Is this sinful enough? You tell me

Also, I've gotten so many emails because of this fanfic that I'm surprised my phone hasn't given up. Still as loyal as if brand new, I see. So! Forgive me if I don't reply to any comments, it's through the emails I get that I see them!

iii: sin

It did not take them too long to leave, Manon's mom appeared a minute after Alya's dad and she drove Marinette home. Her parents are washing the dishes from dinner when she arrives, and they compliment her costume and then shower her with a new pastry they want to sell in their bakery. It is delicious, creamy and has a nice vanilla touch. Marinette sneaks some into her bedroom and Tikki flies out the pocket of her dark outfit, accepting the baked good gracefully and then heads over to the desk to eat it.

Marinette decides to write on her diary then before showering and changing for the night. Her Kwami helps her remember all details of her day and they spend a great deal of time talking about how Chat Noir, the real Chat Noir, appeared at the party and no one else knew but them. She swears she will punch that cat once he sets foot in her bedroom and send him flying through the wall. Even if it was fun to spend some time with him, what he had done was too dangerous, and Marinette does not feel furious, but she does want to punch him, both for his antics and the amount of cat puns he cracked in the few minutes they spent together.

Tikki laughs at the face she makes and the teen sighs in annoyance, telling her friend that she can go to bed because now she is far too agitated to sleep right away. And so the red little thing flutters to the divan and makes herself comfortable on one fluffy pillow, almost immediately falling asleep. Marinette stays awake glaring holes at the desktop of her computer and kicks off her shoes, still unsure of what to do. She grabs the first book her hand can find and heads to the loft where her bed is, coming to the decision that reading will soothe her nerves.

She does not get the chance to crawl towards her pillows for she is hauled in their direction and a body pins her down to her mattress, its warmth familiar. "Hey, Princess." She hears the oh so familiar voice through the heartbeat in her ears and she registers the glinting pair of green eyes staring at her from above. Her mouth opens, air rushing into her lungs, but his hand covers the lower half of her face until she calms down and when she does, he smirks at her. "Did I mention that you look absolutely beautiful in this costume?"

"Chat." She says in a warning tone and he rolls his eyes at her, shifting until he is on his knees and she can sit up. "What are you doing here?"

Her voice is a hiss and he places a hand on his chest in mock-hurt. "This is the third time today you ask me this, Princess."

"Now, of all moments, I have the right to ask this."

Chat waves her off with a dismissive motion of his clawed hand. "Paw-lease, Princess, I just wanted to spend some mew-ments with you like this." She makes a face when he sweeps his palm at her and her eyebrows rise when she remembers that he mentions, at any given opportunity, that he would like to see her dressed in an outfit like his.

Marinette never understood why, though, but she can certainly feel her body warming up when the look in his eyes turns too passionate to bear. He had seen her dressed like this earlier this evening, alright, but he did not look at her like this. Her pulse is wild at the base of her throat, thumping erratically just above the fake bell she wears around her neck. She says nothing, but she does want to break the sudden new wave of tension that fills the room like a shroud, yet words fail her and die on the tip of her tongue when she finds herself too captivated by his glowing gaze.

And then his hands are on her, on her waist, and she naturally lies back down and he settles himself between her parted legs, his chin resting on her sternum. "Did I mention that you look absolutely beautiful in this costume?" He repeats and his voice is... Sensual. She fights to get some air into her lungs.

"You did."

"Do you believe it?"

"I don't."

"Well, Princess," his grip tightens around her and she swallows past the knot of anticipation in her throat. "You should. You know I never lie."

'Had he fantasized about her in a Chat Noir costume before?' is the last thought that runs through her mind before it goes completely blank.

She stands still and holds her breath when he cranes his neck up to kiss her chin and nip at the exposed skin of her neck. Her outfit makes her feel too warm, it is too hot in her bedroom, and winter is just around the corner. It is not the room, she realizes when he moves up, his chest moving against hers, it is her body, it is him; it is both of them that are burning and she does not know what to do with this new sensation. Sure, they made out multiple times before, their hands wandered and he kissed her senseless once or twice whilst keeping her trapped between his firm body and a wall.

But this is a whole new level. Being in her bed, feeling his weight on top of hers, having his teeth play with her ear lobe. She tugged uselessly at the collar of his outfit, knowing better than anyone else that it would not come off until the transformation wore off. Does she want him like that? Shirtless? Pantless? Does she want the both of them naked taking their relationship to the next step? A naked Chat Noir meant revealing his identities and she does not want that – but now they are far too involved with each other, his duty and her personal life have already mixed together.

Will it hurt to show him who she is and have him show her who the one that helps her fight Hawkmoth is?

Chat makes her thoughts dissipate when his mouth finds hers and she finally moves to hold his face between her trembling palms. His tongue sweeps out and meets with hers, she places wet open-mouthed kisses on his throat, pulls his hair, his fingers dip into the curve of her hips and she is aching for him in a way she cannot describe. His kisses trail fire in her skin and her insides are twisting in a pleasant way, and Chat moves up higher, his lips fiercer now and Marinette wonders for an instant if it will leave a mark. Her arms weave around him, hands gripping at his shoulder blades, and she bends her knees so she can –

"Ah!"

They freeze when their hips come into contact, faces just a breath away. Marinette can feel something hard against her inner thigh and her face flushes red, and so does his. Chat holds still for a moment, trying to collect himself and calm his breathing, and once he pulls his wits together, he moves up and away to sit back on his heels, watching her with an unreadable expression and indecipherable eyes. She holds his gaze at a loss of what to do, closing her legs slowly until they touch as she grows more self-conscious with each second that ticks by, and rises to a sitting position. She does not know what to say to break the growing silence, her ears are buzzing and her heart is threatening to leap out of her chest.

He is the one to speak first, voice low in a tone that sends shivers down her spine. "Do I look as ravishing as you do now?" His hair is a mess, messier than usual, as if a tornado had played with his golden locks, his face is incredibly flushed, his lips are so, so red, and his green gaze is filled with desire.

Her lungs seem to be working double-time, pumping oxygen into her brain so she can think through the haze. "Yes," despite all the air she is taking in, the word still comes out as breathless whisper, "Yes, you do."

His eyes light up then and he leaps forward to press one last kiss on her swollen lips, forcing her back until she has to use her elbows to support herself. "Black is definitely your color." Her breath catches in her throat when one of his claws trace her jawline. "It looks meow-nificent on you."

The air comes rushing out of her lips in an exasperated huff and she tries to hit him with her pillow, but he has already leapt out the open trap door above her bed. "Insufferable, ridiculous cat!"
