Prompt is at the bottom. Fluff warning. Enjoy!

Moving furniture was hard, Lucy thought, walking into the still very empty bedroom of her and Natsu's new apartment. She'd just finished setting up the most important things in the bathroom, namely the shower curtain and all their toiletries, and taken the very first shower in their new home. She was very thankful that they'd just ordered pizza so she hadn't had to unload anything from the kitchen except a pair of cups. They'd sat on their dining room floor eating the pizza straight out of the box like the heathens they were.

They'd managed to set up the varied boxes from his old apartment and hers in the rooms they belonged in, but the simple process of carrying all of it up two flights of stairs and then trying to figure out what her boyfriend's chicken scratch on the side of the boxes was tough work. It really didn't help that when she'd peeked inside one, the contents had not at all matched what he'd written on the cardboard.

Lucy scrounged through the backpack Natsu had thrown to the side of the room when they'd first arrived and came up with a soft red t-shirt. She slipped it over her head tiredly and flopped down onto their 'bed' for the evening. It felt a little under-inflated. She laid there for a few minutes, staring at the darkened ceiling, watching the ceiling fan whir. Her legs prickled at the air, having opted to forgo sleep pants and stuck to just her underwear now that it was summer.

Still, the current in the room raised a few goosebumps and Lucy vaguely registered that she hadn't grabbed the blanket she had purposefully laid out on the pillows stacked just a foot away from the bed earlier. Brown eyes slipped shut as her breathing slowed and she wondered when Natsu would get back from the truck rental place.

Natsu heaved a sigh, chucking the keys onto the counter. He ruffled his hair and blinked blearily. Reaching for one of the two cups in the sink, he filled it with water from the tap and downed it. The blue light coming from the oven informed him it was nearly 11 pm. This wasn't that late for him on a normal day, but today had been anything but normal.

He and Lucy had moved everything they owned out of their respective apartments, into a big truck, and then up two flights of stairs. He'd done a lot of the heavy lifting and of course, that stupid stripper and the piercing freak had been conveniently unavailable. He didn't even bother asking their friend Erza who, while physically very tough and strong due to her job as a personal trainer slash kickboxing instructor, very much considered herself a lady and would have just ordered him and Lucy around. Lucy, who'd been brought up as a lady, had put more of her elbow grease towards figuring out where things should go.

He was fine with that, since he didn't really get her whole feng shui thing. If he didn't like the way something looked, he could always just move it later when he wasn't so tired.

Placing the cup back in the sink, he bypassed the door to the bedroom and walked through the living room to get to the other bathroom door. The bathroom was rather generous in size with a full Roman bath that Natsu would have loved to use, had he not feared he would drown by falling asleep. As it was, he saw that Lucy had laid out his soap and shampoo as well as a towel and some clean boxers. Breathing a sigh of relief that he wouldn't have to hunt for any of that, he stepped into the shower and turned the water up hot.

When he exited, the large mirror was covered in a layer of steam. Underwear secured to his waist, he paused in toweling his head when something else caught his attention. A little toothbrush holder was next to the sink, holding one purple brush and one red one.

A happy little fuzzy feeling bubbled in his stomach. He knew it was silly, especially since he'd been keeping a toothbrush at Lucy's for a long time now, but the fact that the little red brush was now his only toothbrush really tickled his fancy. There was no twin waiting in his apartment because now he only needed one for their apartment.

Lucy's used towel was already hung up over the towel rack, so Natsu slung his over the shower curtain rod. He ran his fingers through his damp hair a few times before brushing his teeth and turning off the light. He let his eyes adjust before walking through the connecting door between the bathroom and the bedroom.

His eyes landed instantly on Lucy, curled up on the right side of the air mattress. Something tugged at his brain about the image, but he ignored it, padding into the room and trying to softly lie on the side of the inflated bed.

Unfortunately, he was more exhausted than he realized and his muscles gave out as he tried to slowly lower himself. His resulting plop onto the mattress was heavy and uncoordinated. A little 'eep!' and some motion out of the corner of his eye caught his attention before his body was jostled by another body hitting the mattress.

That body groaned and rolled over, laying over his arm. A hand semi-slapped him during the commotion as the series of soft curves adjusted around his side when he pulled his arm sluggishly from underneath.

"N'tsu?" Lucy's voice was rough and groggy. His arm pillowed her head as she slowly tilted up to look at him through sleepy eyes.

"Yeah, Luce." He turned onto his side to face her, free arm slinging over her waist to slip a hand under what was surely his shirt. She hummed and slung a leg over his thigh and he felt some goosebumps raise at her cool skin. "Ugh, cold…"

She murmured something incoherent and he retracted his hand from the mild warmth of her back. His hand groped in the dark until it landed on something soft and cottony. Fisting the material, he pulled and tried to lay the folded blanket out on top of them. He only managed to set it haphazardly on their legs before giving up.

Re-tucking himself around Lucy, he felt her press her lips thankfully on the skin between his bicep and shoulder where she could reach.

"Welcome home, Natsu," she whispered as she burrowed into the hollow between his shoulder and neck. A smile quirked his lips up as he pressed his face into her hair.

He managed to mutter, "I'm home," before sleep claimed them both.

Prompt: Imagine your OTP having to share an air mattress for the night. Person A is already in bed and comfortable, and person B, very tired from the day, flops down on the other side, thus launching A into the air.
