Snow can wait

Summary:

A blizzard is forcing Senku and Gen to find shelter inside a cave. In order to warm up again, there is no other way but to share body heat. However Gen has a crush on Senku since forever, so he tries to avoid the contact at all costs. Eventually bringing them both into a difficult situation, where they have to come clean with their feelings and help each other out.

Notes:

Just recently I started to watch Dr. Stone. First few episodes I wasn’t sure if I would continue but then BAM, I got hooked badly. How good is this show??!! It’s impossible not to love Senku and all the rest of the characters. Maybe it was also that with Gen’s appearance things changed to the better :D. I’m now in season three and afterwards I will defenitely also read the manga.

This scene is probably happening three years after Senku broke free from the petrification, making Senku legally old enough for these kind of actions. Also seeing that it is almost Christmas and winter, I thought the overall theme would fit the season :)

(See the end of the work for more notes.)

Work Text:

“Senku!! We have to find some shelter or we’ll soon turn into popsicles!”

Gen was screaming with his arms raised over his head in order to protect himself from the snow that came crashing against his face like throwing-stars. His clothes were already soaked with melted snow and his body was shivering uncontrollably. Every step was costing him way too much energy and with the way the biting wind blew the snow right into their direction it was hard to see anything.

“I know a place!” Senku called back over his shoulder and suddenly a hand grabbed a part of Gen’s sleeve. Soon he got pulled forwards into the white masses of snow.

In hindsight they should have never left the village. Everyone had warned them, that it was probably going to snow. However no one had mentioned to them, that the little snow would turn into a full fledged blizzard!

Seeing that it was in the middle of winter they had covered themselves in many layers of clothes, but by now it felt as if Gen was wearing nothing at all. He was sure that he would never ever feel warm again and his teeth were chattering without end.

They had left the village a few hours ago, because Senku had wanted to find sage. He had once seen it growing near the mountains during spring and it was one of the few herbs, which would also still grow in winter. A few of the village children were having a sore throat and Senku had meant to quickly find something to cure them.

What all of this had to do with Gen was beyond him. Any other villager could have done the job, but no, now it was his turn to freeze his ass off, just because Senku had lost all track of time. While they had gathered the herbs deep in the woods, they had not paid much attention to the clouds. Only when the first snow was softly melting on the tips of their noses, did Gen remind Senku of their long way back.

However the beautiful snow soon turned into a death trap. The ice crystals hitting their skin were painful, breathing was only possible through fabric pulled over the mouth and most likely only a Canada Goose Jacket would have protected them well enough from the biting wind.

Suddenly Gen felt that it became easier to breathe and see again. He blinked the last snow from the tips of his eyelashes before he dared to lower his arms.

Senku began to pat his clothes up and down in order to remove the snow that was sticking to the fabric.

“This is a small cave I have once found and marked as an emergency shelter.”

“Oh how well prepared you came. And I suppose you also stocked some firewood in advance?”

Senku frowned.

“Actually no. However there is…,” Senku froze for a second, before he shook his head.

“No, I must have forgotten.”

Gen’s face became ugly.

“Well then,” he also removed the snow from everywhere he could reach and then began to explore the tiny cave. There really wasn’t a lot to see. It was a cave! Some dry leaves on the ground, but no sticks for firewood anywhere.

“We are so fucked.”

“Hm,” Senku’s expression turned grim. He stepped closer to the entrance of the cave and took a last look at the raging storm outside.

“This blizzard will probably last a while longer. We should stay here for now.”

“Lovely,” Gen crossed his arms in front of his chest and leaned against the stonewall behind him.

Without the wind tearing at his clothes he finally regained a little body-heat. He raised his hands, cupped them and blew into them. With some relief he realized that they had not yet frozen off. He continued this, until they became less stiff.

“I wouldn’t do that if I were you.” Senku stuck a finger into his ear.

“Huh? But it’s helping me unfreeze.”

“Yeah, at first. However the moist air which will make them warm up at first, will damp the skin. Just like sweat it will cool the skin in the long run.”

“What?” Quickly Gen put his hands back down and tried to wipe thems dry on his already wet clothes.

“You can put them against the skin of your neck to warm them up.” Senku placed his hands up and under his scarf.

“But then my neck will get cold and I’ll freeze even more!”

Senku just shrugged and finally sat down on the ground, hugging himself.

“So how are we supposed not to freeze to death? Soon it will be nightfall and the temperature will drop further.” Gen stepped forwards and sat down next to Senku. Both started to rub themselves up and down.

“Right. Don’t worry too much about that.”

“I should not? But I don’t want to die in here. Senku! Don’t you have one of your brilliant ideas to share?”

Senku huffed, brought his knees up and rested his chin on them.

“Well there is one way.”

“Yeah?”

“Sharing body heat.”

Gen’s face twitched before he turned it away from Senku.

“Ah, now that you mention that, I think I’m already feeling much warmer now that we are out of the storm. No need to share anything here!”

His laughter was more than forced and although he knew Senku was easily seeing through him, he also knew, Senku wouldn’t push him, unless it was absolutely necessary.

So for a time they sat silently on the ground side by side. Senku had turned into a human ball hugging his legs and Gen could see that he was still shivering. He himself already felt how the cold kept on creeping back under his skin.

Senku was such a pitiful sight, it immediately gave Gen a bad consciences. Seeing that it was a life or death kind of situation there was no room for him being shy. He sighed.

“I guess it can’t hurt to sit a little closer.”

He shifted over until their shoulders made contact, then a little hesitantly he put an arm around Senku’s back and started to rub.

Senku lifted his head up from where it had rested on his knees and scooted even closer towards Gen until their sides were flush together. He also put an arm around Gen’s hips and held him close, while he leaned his head on the other’s shoulder.

Gen’s cheeks were starting to feel hot. If only this wasn’t such a life-threatening situation, he would have rather enjoyed having Senku this close.

For such a long time he had set his eyes on Senku and Senku alone. But at the same time he had soon understood that in Senku’s kingdom of science there was no place for love. As Senku would probably phrase it: love was something that would keep you from thinking logically. He needed all his wits about him in order to rescue all seven billion people on earth. He was busy enough as it was, putting a relationship into the mix would spoil everything and eventually mean the downfall of all humanity. Gen really wasn’t keen on being the reason for the end of all humans.

Therefore he had always held back. Had never advanced a step too far.

The most he had ever dared to do was surprising Senku on his birthday with the telescope. Apart from that, his hands had never lingered where he touched him, nor has he dared to keep watching Senku for longer than necessary.

His heart was bursting with pent-up longing, however now was not the time to let it all spill like an erupting volcano. They had to focus on surviving!

“Does this make you feel any warmer?” Senku asked out of the blue.

Gen gave it some thought and swayed his head left and right.

“A little.”

“Well, there are three stages of hypothermia. In the first, we are shivering, become pale, feel numbness in our extremities and have an increased heart rate. In the second stage we lose awareness, might even start to hallucinate, heart rate and breathing will slow down, then incontinence and at the third stage...”

Gen didn’t want to hear anything about a third stage.

“Senku-chan!! I get it! You don’t have to go on.”

“Ah, I was merely stating facts.”

“And I don’t like those facts. Now go on, tell me what I have to do in order to keep us warm.”

Gen expected a wide grin to appear on Senku’s face like it usually would, when he was allowed to do things his way. However Senku’s expression remained perfectly calm, when he lifted his head and began to untangle the scarf from around his neck.

“We have to share body heat. This doesn’t really work as long as we are wearing clothes. Therefore, we need to undress and then get as close as possible and bury us under all the clothes we got. Like a cocoon.”

“Got it...what?!” Gen’s mouth fell wide open and he stared at Senku who was still continuing to undress himself.

Watching him sent goosebumps over Gen’s skin but rather in an unpleasant way.

“No...I can’t.” Gen shook his head, once again he felt his cheeks heating up. He cursed inwardly for the fact that he could still blush through these freezing temperatures.

“If you want to die here, go ahead. I think we saw each other naked plenty of times before, so what’s the big deal?”

Before Senku removed his underwear he placed the cape and scarf on the ground, creating a makeshift bed. Then he was about to remove the boxers, but that was the moment when Gen decided to look away.

Only when he heard the rustling of fabric, did he dare to turn back around.

Senku now lay comfortably on the ground covered with his tunic, a jacket and other items. His head was propped up on one hand and the other hand was invitingly patting the space next to him.

“Get over here Mentalist.”

Gen’s face had turned crimson and ultimately he had to raise both hands in an attempt to hide from the situation.

“I’m waiting, don’t let me freeze my ass off.”

“I...I…,”

For a second he briefly considered if dying tonight was an option, but actually he rather liked being alive.

Soon Senku’s voice drew him back to the here and now.

“If you are too embarrassed I turn around. Just hurry and come over.”

Senku turned around and Gen was now looking at his back, that was still peeking out a bit from under the tunic.

‘Fuck, fuck, fuck,’ he cursed inwardly. Finally he clenched his fists and accepted his fate. He started to undress with lightning speed, threw all the clothes on top of Senku’s and before he himself would freeze to death, he hurried to get under the mountain of fabrics and next to Senku. Although there wasn’t a lot of space under the clothes, he tried as best as he could to not make any skin to skin contact with the other.

Now they were lying back to back with less than a centimetre of air between them. Still Gen could well feel the heat which came radiating from Senku’s back. This heat was like a magic spell, inviting him to get even closer and it took him his entire willpower to prevent any movement. Even if his legs would soon become numb, because of the awkward position Gen had to remain lying in, he wouldn’t move, come what may.

Gen sighed. Finally his body stopped shivering, however the knowledge that a naked Senku was lying just behind him, was almost making him tremble once more.

He bit his lips hard and forced himself to remain calm, which worked until Senku pressed his back against Gen’s. A yelp escaped his lips and he wanted to protest but his body welcomed this new source of warmth in a way that did not allow any arguments.

Once more he sighed and handed himself over to fate. Maybe this was meant to happen to finally cure him from his stupid feelings towards Senku. Clearly Senku wasn’t the least bit affected, therefore Gen had as much proof as he needed to know, that there was absolutely nothing between them.

“Better?” Senku asked.

“Hm,” Gen nodded and for a while he managed to steady his racing heart and breathing.

Just when he thought he could make it through the night like this, Senku spoke up once more.

“Do you have any idea what would be even better than this and guarantee us a ten billion percent higher survival chance?”

Instantly all the colour drained from Gen’s face. He already had a bad premonition. Before he could stop Senku, he continued with his theory.

“We should embrace us and hold us close in our arms. Therefore we could protect our core much better...like this.”

Without further ado and any kind of agreement from Gen, Senku turned around pressed his front against Gen’s back and slid an arm around Gen’s hips until his hand was resting on his stomach.

“Fuck!!!” Gen screamed out and almost jumped out from under the cover.

“Oh, sorry not sorry for touching you with my cold hands,” Senku snickered and his breath fanned against Gen’s neck.

Not able to help it Gen’s head and neck turned scarlet, which Senku interpreted in his own way to confirm his theory.

“See! Like this it’s much better. Your skin is already heating up.”

“Absolutely NOT!”

Gen grabbed Senku’s hand and pushed him backwards while inching as far away as possible from the other’s body.

This was way too close! One wrong movement and even Senku would find out about Gen’s perverted thoughts which were already manifesting between his legs.

“No?”

“NO!”

“Ok, but if we don’t hold us like this our chance for hypothermia is ten billion percent higher.”

Gen remained stubbornly far away, although there was less than an inch between them.

“Mentalist...just turn around.”

“Which part of ‘no’ aren’t you getting?”

Senku chuckled, then Gen could hear movement, until a voice spoke right next to his ear.

“What happens inside the cave, will stay inside the cave. There is nothing you need to be embarrassed about. If you want to, we will never ever speak about this incident again, provided that we make it out of here alive. So, do you trust me?”

A shiver run through Gen’s entire body the moment Senku’s breath made contact with his ear. By now he wasn’t cold at all! He felt like a living torch! Actually he had a mind to pull the clothes from his body to get clear-headed again.

But Senku had a point. He did trust him. If Senku promised to never mention this day again, then he wouldn’t.

“Fine.”

Gen closed his eyes, bit down the inside of his cheeks and in one fluid motion he turned around into Senku’s welcoming arms. Gen was well aware of his erection that was now pressing right against Senku’s groin, while Gen’s arm sneaked around Senku’s torso. The man had asked for it! Gen didn’t dare to open his eyes. This was the end. Now Senku knew everything. After tonight he would probably still talk to him, but their relationship would be a different one.

Senku cleared his throat, reached out and put his arm around Gen and pressed him closer.

“Well, this is a completely normal human reaction to intimate physical contact. You don’t have to feel ashamed.”

Gen’s eyes flew open.

“Clearly YOU don’t have this problem!” Gen’s voice sounded feeble. His head started to become dizzy from lust, but he could absolutely not allow himself to lose control.

Senku shrugged and replied nonchalantly.

“I just never cared enough about this kind of actions. Did you have any partners before?”

Gen cast his eyes down, focusing on Senku’s collarbone.

“Yeah, a few.”

“And do you miss them?”

Gen shook his head.

“Nah, it had never been something serious. At the time I got petrified I was single.”

“But it explains a lot. Then this is probably happening because of long term withdrawal. When was the last time you had sex?”

How could Senku ask such a question with such a straight face. Gen’s expression distorted.

“Well….several thousand years ago you genius.”

Senku smiled.

“I thought so.”

Gen still couldn’t believe that they were scientifically discussing his boner. Damn! He wanted to scream at Senku for not being able to grasp the obvious. I am attracted to you! I want to be close to you and your touch is driving me crazy! Gen wanted to howl all those things at Senku, but instead he bit his tongue. If Senku simply believed he was sex-starved, then maybe they could still remain friends after tonight.
“But the solution is simple. I can help you take care of this.”

For a second Gen felt like the green petrification light had struck again. He couldn’t move a single muscle, but then his eyes became as large as saucers.

“Senku-chan! I kill you if you touch me!” Gen hissed through his teeth. He was this close to losing it!

Senku, who still looked as if they were discussing the weather smiled.

“But an orgasm has many benefits. Especially in this kind of situation. The body temperature will rise, then there is oxytocin and dopamine getting released and finally all the feel-good serotonin.”

Gen couldn’t believe it. Senku was talking about sex as if he was citing one of his chemical formulas. Right now Gen just wished to run far, far away. But although Senku was explaining an orgasm in such a matter of fact voice, it was still able to kindle the flames of lust inside Gen.

“I don’t care about the benefits! The answer is still no!”

“Hm, ok.”

Without any prior notice Senku suddenly took Gen’s hand and put it between his own legs.

Gen instantly meant to pull away, but Senku held on tight. After just a moment he felt Senku’s cock slowly getting harder. Gen’s face lost all the colour.

“See? I’m also not entirely immune.”

“Senku...please,” Gen pleaded with his voice almost gone. Please what? Please let me go? Please don’t stop? Gen didn’t know what he wanted to say.

Senku chuckled, the way he always did when science fascinated him.

“Actually it is quite interesting how it feels ten billion times better getting touched by you, instead of touching myself.”

Gen’s face was crimson red and he could only stammer a reply.

“I...I had no idea.”

Senku made Gen’s hand move up and down, which in turn made Senku gasp and then chuckle with his eyes closed.

“How astonishing. It clearly activates my amygdala.”

Spare him these scientific facts! Gen couldn’t take it anymore. He felt hot and cold at the same time. The fact that they were trapped inside a cave with a blizzard raging outside was long forgotten. His entire world revolved around the pulsing thing in his hand and Senku’s lips dangerously close to his own.

He only needed to lean in. What difference would it make by now really?

However before he could put his plan into action, Senku made the most hilarious proposal.

“I think we should do this to each other.”

“What?” Gen awoke from his trance. With his eyes wide open he now stared deep into Senku’s red eyes. He looked determined, not the least bit embarrassed.

“Provided you are ok with this of course. I would be.”

“You?”

What was happening? Was Senku only acting in the name of science or could it be...? No, Gen inwardly shook his head. This was probably just another experiment on the long list of Senku’s science achievements. Reading about sexual pleasure in a book was all good and well, however actually experiencing it, must be mind blowing even for Senku who would rate it in the end like an experiment with himself as a target group.

Senku leaned forwards and placed his lips right next to Gen’s ear. When he spoke he brushed against the soft skin.

“Are you ok with this Mentalist?”

His voice was husky, almost erotic. Gen’s brain was probably playing tricks on him.

There was nothing he could do against the built up desire in his chest. It was like a dam had broken inside Gen and he pressed their bodies closer together. With a trembling voice he gave his consent.

“I want this, a lot.”

“Hm,” Senku hummed and then a hand sneakily went forwards and around Gen’s cock, making him moan into Senku’s shoulder.

With a precision Gen wouldn’t have expected from someone who was just experiencing his first time together with another human being, Senku’s hand was sliding up and down, making sure to hit all the right spots. Gen’s muffled pants were the only sound within the cave. He tried to also move his hand in a way that would Senku make feeling good, but the intense stimulation coming from his own erection was messing with his brain. Coordinating anything was almost impossible.

He registered Senku’s voice only with a few seconds delay.

“Your cerebellum is taking over, sending signals to tense your muscles pre orgasm as well as your frontal cortex which might make you fantasize about previous encounters.”

“Will you...shut up! The only thing I’m thinking about is you!”

Gen panted and leaned away from the lovely smell of Senku’s neck. Instead he finally captured Senku’s lips to finally make him stop reciting science facts.

Senku welcomed it and they skipped the soft kissing and instantly made them messy. Their tongues started to entwine and now even Senku seemed to have a harder time breathing. Both their hands moved in the same rhythm. The pre-cum that came leaking from their cocks, was helping to make the motion more seamless and besides the noise from their kissing, the wet sound of their hands was making Gen absolutely lose his mind.

He had to break the kiss, when he felt getting closer to his orgasm.

“Ah Senku I….” Once again he buried his face in Senku’s shoulder. His panting was heavy and when the feeling became too overwhelming he softly bit into Senku’s neck. “Ahh!”

Hot cum splattered over Senku’s hand when Gen reached his climax. However even though Gen was almost seeing stars from the intensity of the feeling, he still continued to move his own hand up and down Senku’s shaft and he was well aware of the fact, that although Senku’s face wasn’t giving much away, he was also close.

Gen sucked at the thin skin along Senku’s neck and finally even the scientist in his arms couldn’t hold back a moan.

“Gen!”

One more stroke, two and Senku pressed them closer together. Sticky liquid was running over Gen’s fingers and it was absolute bliss for him. He held on to Senku, feeling his body trembling in is arms, while he himself tried to catch his breath.

Before Senku could say anything stupid Gen quickly spoke up.

“If you tell me anything about what my brain is doing right now, I will strangle you!”

Senku chuckled against Gen’s ear.

“I would never.”

Gen felt how Senku’s fingertips were gently stroking up and down his back. Never before in his life had Gen felt this content and safe. Even though they were actually in a life or death situation, he didn’t fear death right now. He was so happy, he could hardly contain the radiating smile spreading from ear to ear.

But before Senku could see it, he simply leaned his head against Senku’s chest and closed his eyes.

“Hm, now I’m tired.”

“I could tell you why this is….but I spare you. You can sleep. I will watch over you, in case your temperature is starting to drop again. Sleeping within the cold is actually quite dangerous.”

“I’m not cold at all. I think I have never ever felt this warm in my entire life.”

Gen felt how the drowsiness overtook him. However before he lost consciousness, Senku pressed a kiss on his head. Or was it already a dream?

*

*

The next day Gen was woken by a soft light that shone in from the entrance of the cave. He rubbed his eyes, until with a sudden start, the memory of last nights events came crashing in. Quickly Gen glanced over to his side, where Senku was still fast asleep.

Gen lifted the fabric, which covered the both of them and he peeked down. Yes, yes, they were still very much naked.

Mortified, Gen tried to leave their cocoon made from clothes, without waking Senku. Luckily he knew that Senku was usually completely knocked out once he fell asleep, therefore he was confident that his actions wouldn’t stir him. Soon he had made it to the outside world and was greeted by a very cold air. Biting his teeth together to prevent them from chattering, he grabbed his clothes, which were still packed on top of Senku. One layer after another Gen put over his goose bump covered skin until he sighed a breath of relief. Fully dressed he tiptoed towards the entrance of the cave, where he was greeted by the most beautiful sight. The wood was covered in snow and the morning sun made it glitter as if there were a million diamonds on the ground. It was a sight to behold, but still not as beautiful as seeing Senku coming undone. Haaa, all the impressions from yesterday made Gen’s heart feel conflicted. He had no idea how he was supposed to face Senku in the future. Could he pretend nothing ever happened? He was still debating with himself, when he heard a loud groan coming from behind him.

“Ahhh, my back hurts! I hate sleeping on the ground!”

Gen turned around with his fake smile plastered all over his face.

“Senku-chan good morning.”

Senku blinked a few times, until his red eyes landed on Gen. They lingered a moment too long for Gen’s taste, until Senku finally turned back around and got into a sitting position. He rubbed his spiky hair and yawned.

Since his entire back was exposed, Gen hurried to focus back on the snow outside. Only when he heard the sound of fabric, did he dare to take a peek.

While Senku was putting on his clothes as well he started to speak.

“Mentalist, would you please come over. I think we need to talk.”

Gen swallowed hard and his stomach tensed. Slowly as if in slow motion he stepped over.

“Yes...you mean about last night?”

“Yeah, I think I should be honest with you.”

Somehow Gen didn’t want to hear what was going to come next. He simply held on to the fabric of his scarf and pretended that last night had been no big deal at all.

“Just forget…,” Gen was about to make them shrug of everything but Senku held up his hand.

“The truth is, sex is actually a bad idea in order to fight hypothermia. It’s the same like blowing into your hands. Sex will raise your body temperate and heart rate, but at the same time it will make you sweat, which will also make your body cool faster. I’m sorry about that. But what wasn’t a lie was the part that I really wanted to do that with you. I always felt like you are interested in me, but held back because you thought that I might not be into things like that. Let me tell you this. You are wrong.”

Gen’s eyes became wider and wider. Was he still dreaming? He put his arms behind his back and pinched himself hard.

“I might not be the most experienced, but…,” Senku cleared his throat. “I read a lot about it and researched the topic regarding gay sex with...videos. So I’m not unaware about the concept. Also I was already more attracted to men, even before we met.”

“You, what?”

Senku put a finger into his ear and tried to look smug.

“What I am trying to say is, I like you and I don’t mind getting intimate with you.”

Gen’s mouth fell open.

“Senku...”

“Provided I didn’t misinterpret your signs. So, what do you say?”

For a moment Gen was too shocked to react. Was this really happening? But ultimately Gen started to laugh.

“You are really something Mister Science.”

He then stepped over and hugged Senku tightly.

“I want to be together with you forever! I want to be close to you and never ever part ways.”

“I’m glad.”

Senku put his arms around Gen and held him tightly, while nuzzling his soft hair.

“Now, I need to tell you something else.”
Gen leaned backwards, looking sceptical.

“What?”

“This cave...it’s actually kind of special. There are some hot springs running underneath it, therefore the ground is like an underfloor heating. Actually we had never been in any danger at all.”

Senku looked innocent, if not for the slight blush creeping along his nose.

Quickly Gen hunched down and reached for the floor with his hand. His eyes went wide, when he felt the warmth coming from underneath.

“What the!!!?? Senku! You tricked me!!”

Senku crossed the arms in front of his chest and grinned.

“I didn’t plan for us getting into the blizzard, but the cave was the best option. Actually I didn’t lie, I only held back some information and seeing how the situation unfolded, I just grasped the good opportunity.”

Gen had a mind to strangle Senku, when he got up from the ground again.

“Actually manipulating people's emotions is my part, but seeing that I very much like the outcome, I will overlook it.”

Gen smiled and Senku returned it.

“Now, let’s go back to the village.”

Senku reached out and took Gen’s hand in his, he didn’t let go, not even when Kohaku and Ginro came asking question. Senku held on and Gen couldn’t haven been any happier.

 

Notes:

I had to do a lot of research for this story :D, which was fun. I learned much about human brains during orgasm, hypothermia and some more stuff. I felt like otherwise I wouldn’t be able to portrait Senku in a good way, if not for adding some science facts in there.
Hope you liked the little one-shot.

Please leave a comment or a kudo, I’m always happy to hear from you! Also chances are higher I might write another story ;)
