Chapter Text
For as long as anybody could remember, Derek and Stiles have been, well, DerekandStiles! Not like- EW- not like that. But they’ve always been extremely close. Close enough that one might think that they were romantically inclined. They weren’t, but people talk.
However, Stiles could very much so attest that they were in fact, not together in any way ,shape or form. He could even provide you proof if you needed it. Exhibit A, the sound of the headboard slamming into the wall at an alarming rate while some girl lets out a litany of moans and curses and “DEREK!”s.
This is not the first time Stiles has been left tossing and turning trying to get some sleep through Derek’s romps in the bedroom, far from it, actually. You see, Derek is what some may call a ladykiller, though Stiles prefers to just flick his shoulder and call him a whore.
Normally it wouldn’t even phase Stiles, really it wouldn’t. Normally Stiles would grudgingly roll over, get out of bed, put in his headphones and listen to some ‘that isn’t even music it’s just a lot of noise and some screaming, God dammit Stiles this isn’t 2006 anymore’ (Derek’s words, not his) and maybe work on getting his Worgen to Pandaria.
Which is about a million times better then how Derek reacts every time Stiles has someone over. Stiles lays there a moment thinking about last time he had a boy over and how Derek stomped around their two bedroom apartment ‘cleaning’. He even tried to come into Stiles’ room to get ‘the, uh, thing. You know, the one I lent you a few days ago that I need back for my landscape photography class’ (there was no thing).
At the thought, Stiles starts to get more than a little miffed. It’s not that Derek’s nonsense had ruined what was some amazing sex, it’s that Stiles is tired and cranky and his brain feels like goo trying to remember all the functional groups for his organic chemistry midterm tomorrow. Today, Stiles thinks after looking at the clock. In six hours. Shit.
Stiles heaves himself up from the bed and over to Derek’s closed door, where he gently pounds on the door with all his strength. “Derek!” Stiles shouts exactly in time with whatever girl he’s in there with moaning out Derek’s name in a very climactic way (ew). “DEREK!” Stiles shouts again when the headboards slamming doesn’t even slow “I swear to you if you don’t keep it down I am going to bring in some 9.0 molar acetic acid from my midterm tomorrow and switch it with the one you use for your stop baths!”
That seems to get Derek’s attention if the sudden scramble of feet across the room is any indication. The door flies open and Derek appears, wild eyed, sweaty, and breathless… not to mention nude. Very, VERY nude.
“You wouldn’t!” Derek growls out at him, voice wrecked from his previous activities. “that would absolutely ruin all my negatives for MY midterm next week!” Stiles crosses his arms, chin jutting out defiantly “Kind of like how you’re ruining my midterm by keeping me up all night?”
Dereks shoulders sag with guilt, head down. His green eyes look up at Stiles through his long lashes, “I’m sorry, babe, I completely forgot. Why didn’t you say something earlier?” Stiles can’t stay angry with Derek when he uses that look, he just can’t, but that doesn’t mean he can’t pretend.
“Well, I figured I could wait until you were finished. I just didn’t figure I’d be waiting THREE HOURS for you to be finished.” he peeks his head into the room to find none other than Erica Reyes laying flushed and panting in Derek’s very rumpled bed “How can you even handle that for that long!”
Erica looks up at him and starts laughing. “What can I say?” she gets out between giggles “Derek is just that good! He does this thing where h-” “Okay thank you Erica, you can go now” Derek spits at her trying to close the door behind him.
“Are we done here? Can I maybe go rest my addled brain now?” Stiles asks “You know I need to be in prime condition to even have a prayer of passing this midterm. What am I going to do? What if I forget the difference between Cis and Trans?! What if I forget how to draw a benzene ring oh my god what is a ketone?!” He rushes out, beginning to panic.
“Stiles!” Derek exclaims when he notices Stiles’ breathing beginning to pick up “Stiles you’re going to be fine”
Stiles keeps babbling trying to list the different kinds of organic compounds to reassure himself “Alkyl halides, ketones, aldehydes, carboxylic acids, ethers, esters, amines and amides, alkyl halides, ketones, aldehydes, carboxylic acids, ethers, esters, amines and amides.”
Derek sighs at Stiles “you forgot alcohol” he mutters, after becoming very familiar with the compounds having had to quiz Stiles on them for weeks.
Stiles momentarily stops, looks at Derek and says “Yes, alcohol would be very good right now” before bursting into a fit of giggles. "Come here, babe" Derek says pulling him in for a hug and burying his nose in Stiles' hair "you are top of your class, you're going to be fine. I promise. I'm sorry for keeping you up all night"
Stiles relaxes into the embrace and quietly responds "actually Lydia is top of the class. I'm 2 percent behind her." Derek chuckles "Lydia is also a terrifying, ginger genius who doesn't count." "Strawberry blonde." Stiles snorts into the taller man's muscular chest, causing Derek's dick to twitch a little at the feeling.
The bedroom door opens behind them and Erica huffs out a laugh "if Derek didn't just spend the past 3 hours murdering my vagina I would be concerned why he's holding a half naked man while fully nude."
Derek tenses before Stiles pushes off him with a start. "Oh my God I am so done with this right now!" He cries before scurrying back to his room and falling into a fitful sleep.
