They’re three days into a case in a small town in the fuck knows where Texas and Derek is desperate to get a full nights sleep. Unfortunately for them the only hotel in town did not have enough rooms for everyone so he was stuck sharing not only a room but a bed with Spencer Reid.
It's not that he didn't like Reids presence but for the most part the kid doesn't really sleep, maybe a few hours a night if he's lucky so a usual night is filled with Derek trying to tune out the dim lights and shuffling of book pages.
Derek sent a quick thank you to whatever Gods may or may not exist when Spencer turned off his lamp and snuggled his way under the covers at 11:00pm. He turned off his own light and settled in for the night.
However his slumber did not last nearly as long as Derek had hoped, he was woken up by a low groaning sound coming from Spencer. It only took a moment of consciousness to realize that Spencer had an arm slung across Derek's chest and one of his long legs over his thighs.
It's not the first time Spencer has ended up spooning him in his sleep but it's definitely the first time Derek could feel the young doctor's erection pressing into him. Now the groaning made sense, Spencer must be having one hell of a dream.
Spencer started slowly shifting his hips, essentially grinding into him. Derek should wake him up or at least shove him off, as much as Derek has dreamed about being touched by Spencer he's asleep and has no idea what he's doing.
On the other hand, Spencer would be mortified if Derek woke him up like this. Derek was pulled out of his moral dilemma by Spencer burying his head into his shoulder. Feeling the vibration of Spencer's little noises directly on his skin was sending heat rushing south.
Derek really wanted to just wait for Spencer to be done and go back to sleep but his body had other plans. He could try to get out from under Spencer's grip and go to the bathroom and take care of himself but that would probably wake up the young doctor who rarely got to sleep as it is.
So Derek made the sleep and lust clouded decision to let his hands wander lower. He shoved his sweatpants down just far enough to free his aching cock. He sucked in deep breath and mentally scolded himself for what he's about to do.
As long as he doesn't actually touch Spencer he's not doing anything wrong. He glances over at him to ensure that Spencer is still in fact asleep and finally grasped his length. He was so pent up from days of close quarters and not having a chance to masturbate that he knew this wouldn't take long.
If Spencer's uneven breathing in his neck was any indication Spencer wasn't too far off either. He could feel the small wet patch of precum soaking through the younger man's boxers against his leg. He imagined it was Spencer's slender fingers on him instead of his own and timed his strokes with Spencer's hip thrusts to keep up his little fantasy.
“Mnnn… Derek," Spencer whined. Derek stilled for a moment worried Spencer had woken up, but given that he hasn't stopped grinding into him he's definitely still asleep. But that means Spencer was dreaming about… him.
Derek bit back a groan at the implications and worked himself faster. He's been crushing on the guy for a while but was never given any indication that he was into him or men at all. Spencer's sweet little noises of pleasure were going to be burned into his memory.
Spencer's grip across Derek's chest tightened and he whined again “more, Der- please” Spencer was going to be the death of him. He rubbed his thumb across his slit to spread percum down his shaft.
He desperately wanted to touch him, to feel his skin .He knew it was wrong but when Derek used his free hand to lift Spencer's shirt up to lay a hand over his waist nothing had ever felt so right. Spencer didn't seem disturbed by the contact so Derek ran his hand over his abdomen feeling the little line of short hair leading down below his shorts.
Derek was practically thrusting up into his own hand at this point, the slight shamefulness of his forbidden actions only making this whole thing so much more erotic. It would definitely be crossing a line to touch Spencer's penis so instead he shifts his attention upward and lightly brushes across his hard peaked nipples.
Reid let out a loud moan at the contact and nuzzled his head Derek's neck, the hot breath on his skin sent shivers through Derek's whole body. He squeezed around the base of his cock willing his orgasm away not wanting this to be over yet. He didn't have nearly enough self control to stop touching himself entirely but he slowed to a glacial pace.
He slid his hand back lover down to his lean waist and over his bony little hips, he didn't linger there long however, his boxer leg had ridden up so far with his grinding that Derek could enjoy the exposed skin of his thighs.
He felt his way up the leg slung over his own and trailed up to where his ass cheek was hanging out of the loose fabric. Derek hesitated for a moment but ultimately decided to give his but a little squeeze. It was so worth it because Spencer whined and his grinding became erratic.
Derek could tell that the young man was close so he went back to his own unrelenting pace bringing himself back to the edge of orgasm waiting to hear the sweet noises Spencer would make when he came.
He stroked his thumb back and forth against the soft flesh of his ass relishing in the way his muscles clenched and his orgasm washed over him. He thrust his hips up one final time and whimpered into Derek's neck. His cock pulsed against Derek's thigh and the warm liquid soaked into his sweatpants.
Derek couldn't hold back anymore and gripped his fingers into Spencer's hips as he came, he stroked himself though it, aiming himself so all of the thick white ropes landed on his chest. He rode the waves of pleasure that washed over him wanting to enjoy this as long as he could.
When the post orgasm haze cleared up he gently removed Spencer's arm from across his chest, he stripped his cum soaked shirt off and balled it up on the floor, it would be an easy enough excuse to just say he got too hot in the night if Spencer questioned it.
He tucked himself back into his pants and put Spencer's arm back around him the same way it was earlier. Derek got the best night's sleep he's had in a long time.

He awoke with the startling sound of Spencer's alarm clock and heard him groan into his shoulder. He was happy to realize they are still in the exact same position they went to sleep in. Spencer must have realized it too because he rolled over and shot up. A blush crept up his cheeks. “morning Reid '' Derek said, still half asleep.
“Oh god i'm so sorry i didn't mean to…” Spencer squeaked out. Derek smirked “it's okay, I don't mind cuddling pretty boy” to up his teasing game Derek shot a wink at him. Spencer moved to get out from under the covers but stopped and shoved the heels of his hands into his eyes. He must have realized he had cum in his pants last night.
Derek felt a slight pang of guilt, clearly he was embarrassed about this. “You okay kid?” not guilty enough to stop enjoying the way he squirmed “yes, just some um weird dreams, gonna shower” he got up and sprinted to the bathroom. Derek laid back down and smiled at the ceiling, he really hopes Spencer cuddles up against him again tonight.
