Day 25 (Day 30): Doing Something Hot

"Oh god..." John sighs. "That's good."

"Is it?"

John bites his lip and groans. "Isn't it obvious?"

"Well, of course, but-"

"Then stop asking and keep going."

It all started because of the stupid weather. Yesterday it was a nice temperature outside, Sherlock didn't even wear his coat all day. They didn't need to turn the heat on, as they usually do by this time of year, but since it was reasonably cool and warm at the same time, they left it off for another week or two.

By the time they woke up this morning, they were icicles. It was freezing. It was a cold that they thought would be warm by the afternoon, but it stayed cold all day. The sun was bright, but the breeze was cold. It was the type of weather that made you want to stay in bed all day.

Unfortunately, they couldn't, because Lestrade called with a case that kept them out of the cold flat all day. By the time they got home after dinner, it was still cold. They turned the heat up and took turns in the shower, then they met in bed for sleep.

That's when John said he was too cold to sleep.

"I want to sleep with your coat on," John had said over an hour ago.

"No. If one of us gets to, it's going to be me."

"Didn't your mother teach you to share?"

Sherlock snorted rudely. "That woman taught me no-"

"You say one bad thing about your mother and I'll kick you in the bollocks."

"Mmm," is all Sherlock replied.

They spent more minutes laying in the silence. Their feet rubbed together in a way that built heat between them, and finally they looked at each other in the dark and came to the same mind.

They darted at the same time, their mouths meeting in the middle and clashing full of teeth and lips.

"Ow-" John started to say before Sherlock attacked again, this time his lips soft against John's.

John sighed and Sherlock moaned, pushing John onto his back and climbing on top of him.

An hour later, they're in the same position, only now John is on his front and Sherlock is still finger fucking him, which he has been doing for nearly forty-five minutes.

Heat licks at their skin, and they're glad they're doing this because their body temperature has raised a significant amount since trying to sleep in the cold room. The heater is still on, but John has half the mind to get up to turn it off.

If was being warmed any other way than Sherlock's fingers up his arse, Sherlock's sweaty skin flush against his, and Sherlock's breath steaming up every bit of him that Sherlock's mouth can reach, he would.

John grinds back on Sherlock's hand. "What are you even doing back there?" he pants.

Sherlock shifts and John feels his breath now against the back of his thigh.

"Exploring," Sherlock says.

John groans. "Just fuck me, Sherlock..."

Sherlock hasn't yet. John penetrated him a few weeks ago, after Sherlock begged and John didn't even think about saying no, but Sherlock hasn't had the honor yet.

Sherlock kisses the small of John's back. "Are you sure?"

"God, if you don't then why the fuck else have you had your hand up there for almost an hour?!"

Sherlock chuckles. John sighs when he feels Sherlock's fingers vibrating inside him.

"Okay," Sherlock says after a few more minutes of twisting his fingers in and out of John. "I will. Condom?"

"No need," John says. "We just got tested, remember? We're good."

"Are you sure?"

"I'm not planning on fucking anyone else, are you?"

Sherlock gasps as if offended. "Of course not."

"Then shut up and get your cock in me!"

Sherlock pulls his fingers out and kisses up John's back. "Okay," he whispers in John's ear. "Turn over."

Sherlock, of course, has never felt anyone under him like this. Sure, they've gotten each other off by mutual hand jobs in this position, and he loves to suck John to completion while John is laying on his back sprawled over the bed, but never like this. Never has he ever been on top of someone, surrounded by the heat of their body on his really rather harder than pretty much ever dick. He's never felt this good.

"Oh, John..." he moans against John's mouth.

"Good, right?" John asks, his fingers tangled in Sherlock's hair.

Sherlock tightens his grip on John's hips and thrusts again. He groans low from the back of his throat and bites John's lip. It makes John tighten his arms around Sherlock's neck.

Sherlock tries his best to be good for John, to not only think of himself, so he rubs his hands over John's thighs, hips, up to his ribs and around shoulders. John's skin is burning against his; it feels like their bodies are being welded together with each thrust.

"I love you," Sherlock whispers.

"I love you too..." John gets out before a loud moan when Sherlock thrusts in as hard as he can.

Sherlock's ready to finish only minutes later, which isn't surprising to John. He pushes a hand between him and Sherlock, stroking in time with Sherlock's thrusts and eventually clenching tightly around Sherlock's cock and coming first. Sherlock follows seconds later, shoving up hard into John and digging his nails into John's skin as he comes and comes for what seems like forever.

They catch their breath and Sherlock falls off John, shifting to his side of the bed that's gone cool from not being used.

"Oh god," Sherlock sighs.

"Good?" John asks, reaching for a tissue to clean up.

"It's so hot."

John laughs. "You're hot? I just had someone on top of me for an hour."

"And that someone is so hot."

John cleans Sherlock up too because clearly Sherlock wasn't planning to do it himself.

"You're hot," John mutters.

"I am hot, my skin is absolutely burni-" Sherlock stops. "Oh. Oh you meant-"

"Sexy hot, yes."

Sherlock smiles. "You're hot too."

"Mmm," John sighs, hovering over Sherlock to give him a kiss.

Sherlock stops him. "I'm too hot!"

John laughs. "Alright, I'll turn the heat down. You straighten up the duvet because you're the one who is going to whine about being too cold later."

"If I get cold later, I'll just do you again."

"You can do yourself," John mutters as he exits their room.

"Rude!" Sherlock calls, settling on top of the duvet.

He does end up getting cold later in the night, but he just cuddles closer to John and continues sleeping.
