Notes:

Better late than never. XD This is my take on Marinette March this year. ^-^ I wanted to finish it entirely to drop it all at once before I did, because I feel bad I don't finish things faster anymore. Anyway, I got through some technical issues, still fighting a cold, and here it is. XD It's a lot of smut. So, if that's your thing, welcome. XD I didn't realize how much was in this until I was editing today. XD Thank you to everyone who answered my random questions while writing this!! I appreciate you all! <3 As always, there will be songs on chapters and then a master playlist at the end. Thank you for reading, and I hope you have fun! XD

Chapter 1: Day 1: All-Nighter

Chapter Text

Marinette Dupain-Cheng had a game she played every night she was home. One that involved her neighbor through the thin walls of her bedroom wall behind her headboard. It was a game of who could come undone the most. Most nights she won, but tonight it felt like he was.

It had become progressively harder for her to get off when all she had dreamed about was his hands on her body rather than her own and his throbbing cock between her thighs rather than her vibrator. She wanted to feel his muscles move beneath her hands, his warm breath against her ear, as he whispered all the secret thoughts, he had about her, and his low moans and oaths as he pumped within her soaking wet pussy.

She wanted it all, craved it all.

His moans filtered through the wall, colliding with her own, as she ran the silicone tip of her vibrator along her wet pussy. Her legs spread further apart, as she ran her free hand up her stomach to capture her left breast into her hand. She caressed the swell of it and pinched her hard nipple between her fingers to tug on it and arch her back in bliss.

Give it to me,” she moaned loud enough for him to hear, earning her a growl from behind the wall. “Are you going to let me win tonight?” She panted and ran the toy down to tease her entrance. “I want to feel your hard cock in my tight, wet, pussy, so bad. I want it filling me, fucking me, making me scream the name I crave to know.”

Another groan came through the wall, and she giggled and bit her bottom lip. “You’d like that, wouldn’t you? You’d like to feel my warm mouth wrapped around that cock of yours, making you moan, and beg for mercy.”

“If you wish to win, you should knock it off,” he teased through the wall with a soft chuckle.

“If you’d pull your weight, maybe I would win easier,” she teased back, causing him to laugh harder.

“Alright.” He paused for a moment before talking louder, as if he was facing the wall instead of away from it, “If I had you in my bed, I’d place your hands on the headboard and fuck you so hard you’d remember me the next day.”

Mmm… try harder.” She smirked and brought her vibrator back up to tease her sensitive clit with a gasp.

I’d lay you back, slip my hands beneath your thighs, slowly part them, trailing kisses up your inner thighs before dipping between them to run my tongue along your pussy, and tease that sensitive clit of yours with my tongue and soft lips.” She moaned, listening to his words. “I bet you’re sweet as honey for me.

She gasped and trembled, dipping her vibrator inside and hitting the perfect spot until she fell apart with a loud moan.

He darkly chuckled, “That’s my naughty girl. Again, for me.

Marinette moaned and slowly eased her slick vibrator out of her pussy and ran it up to tease her overly-sensitive clit. A gasp left her lips, as she brushed it along herself. Another groan fell through the wall, followed by a hiss.

“Three to two,” his words fell into her ears, and she came undone again. “Three to three.”

She rolled her eyes at him and reached behind herself to hit the wall, causing a laugh to follow. Sitting up onto her knees, she faced the headboard and slowly spread her thighs along her silk sheets. Marinette ran her vibrator along her pussy again, circling her clit and brushing past it to slip her toy within herself. She shoved her pillow between her thighs and sat on it, gripping the headboard in her hands, as she rolled her hips to pretend it was her mysterious neighbor.

I wish you were this vibrator in my wet pussy and the pillow between my thighs making me feel this amazing.” She panted and moaned, brushing her clit against the satin pillowcase and causing her vibrator to shift within her tight pussy.

Fuck, princess.” The man moaned and his headboard slammed against the wall, making her wonder what he was doing.

Tell me what you’re doing.” She threw her head back for a moment, causing her long midnight-hued hair to cascade down her back, as sweat coated her body; while, she rode her pillow and toy.

You really want to know or is the mystery more tantalizing?” He suddenly groaned with a few more slams. “Four to three. I’d say you’re losing, princess.”

“Fuck off,” she rolled her eyes and giggled. “Help a girl out then.”

If only this toy was your pussy wrapped around my hard cock, fucking me hard, and making me slam my headboard against the wall instead.” Her neighbor spoke against the wall, running his nails down the texture of it and making her breathing hitch. “If only my mouth was wrapped around one of your peaked nipples, sucking, nibbling, and licking it until you were soaking wet around my fingers. If only my na—” A lascivious chuckle fell through the wall, as Marinette came undone once more.

Four to four,” she breathed.

“So I hear, princess. How many more can you give me?” He teased, and she giggled.

“I can go all night, but can you?” She shifted on her pillow to turn up her vibrator before reaching over for a second one to settle against her sensitive clit. She turned it on and gasped out another moan, settling back down on the pillow and getting lost in the way both vibrators teased her. She arched her back and gripped the headboard, rolling her hips faster until her toes curled and she came undone again with ease. “Five. You better catch up.”

He softly laughed, “I may have to let you win tonight. I don’t know how much more I can give you.”

“Are you giving up?” She panted, licking her dry lips and shifting to grab her glass of water from the nightstand.

“Maybe.” He cleared his throat. “I’m tired.”

She giggled. “This might be the first night I have won in a while with you.”

He snorted. “I’m letting you win.”

“Are you?” She teased and set the glass down. “Too bad. I thought you had me.”

He growled and she heard the sound of a vibrator kicking on.

“New toy?” She hadn’t heard that sound before.

“Maybe.” He groaned, as the sound of his bed hitting her wall began again.

She rolled onto her back, using one hand to pump her vibrator within her slick pussy, while the other teased her clit with her other toy. Her back arched off the bed, as she came undone with him.

“Five to six.” He breathed and hummed in bliss. “You win. I’m fading fast.” His tone came out breathier and huskier, as if sleep was taking him under.

“It’s almost five in the morning.” Marinette slipped the toys from herself and set them beside her on the bed. “God, what I wouldn’t give for your tongue between my thighs, tasting what you do to me.

Damnit, woman.” He groaned and she heard the bed shift beneath him. The sounds of his movements were slow, deliberate, and lazy. She listened, gently running her fingers along her wet pussy and brushing her nails along her inner thigh. Her breathing matched his, listening to his soft moans. She bit her bottom lip and arched her back, circling her fingers along her clit, as she came with the sound of him.

“Six to seven,” they spoke in unison, and she giggled.

God, we’d be dangerous together.” Marinette let her hands fall above her head. The cool air of her apartment teased her nipples and caused them to harden, thinking about what her neighbor could look like. She hadn’t seen him since she had moved in a year ago from her parents’ house.

The silence that followed her words made her giggle and sigh, as she slowly got up to wash her toys and put them away. She had been with a few men prior to this adventure, but no one had made her feel the way this mysterious man did, and he hadn’t even touched her.
