Stiles knows the rules of friendship, and the first rule is to not fall in love with your best friend. He remembers fondly when his dreams were filled with soft curves and red hair, but now they're plagued with black hair and tan skin. It effects the way he looks at Scott, but at the same time, it doesn't.
Stiles comes to the conclusion that he has always been in love with Scott.
He's somewhat lucky that Scott isn't experienced enough with his emotion smelling werewolf nose to know what Stiles is feeling, but Derek has picked up on it.
"Stiles." Derek says, as Stiles comes into his loft. Stiles waves as he goes to help himself to something to drink, and Derek gives him an unimpressed look. "What brings you by?" Derek says, as his phone beeps.
"Tell Braeden I said hi." Stiles says, and Derek smiles despite himself. Stiles grabs a bottle of water, and helps himself to one of Braeden's cupcakes.
"You didn't answer my question. Why are you here?" Derek asks again, and Stiles throws himself down on Derek's couch.
"Aw, Der. Do I need a reason?" Stiles kids, and Derek rolls his eyes but doesn't say anything. "Scott's out with Kira again." Stiles says, and Derek gives him a raised eyebrow look.
"They're just friends, Stiles." Derek says, and Stiles snorts in disbelief. Derek doesn't say anything for a second, and Stiles just watching the baseball game on the big screen television. "You're jealous." Derek says, and Stiles sputters while Derek smiles at him.
"No, I'm not." Stiles says, and Derek laughs. "Now I know why I broke up with you." Stiles hisses, but Derek just keeps laughing.
"You are so jealous. I can smell it all over you. You like Kira!" Derek accuses, and it's Stiles turn to laugh.
"Oh, honey. Thank God you're pretty." Stiles says, and Derek frowns. "Look, I just don't want to talk about it." Stiles says, and Derek leans forward to stare at him.
"Oh." Derek says, and he leans back to stare at Stiles smugly.
"What oh? I hate when you do the oh thing!" Stiles hisses, and Derek smiles at him patiently.
"You're in love with Scott." Derek says, and Stiles faux laugh while standing up to throw away his trash. Derek stands up to follow him into the kitchen, and Stiles steals another cupcake. "You smell like love." Derek says, and Stiles opens his mouth to say something but Derek cuts him off. "And not platonic love. Romantic love." Derek says.
"I have trouble believing that they have separate smells." Stiles says, and Derek smirks at him. "God, I hate your face." Stiles says, and Derek laughs at the lie.
"Yeah, yeah." Derek says, waving him away. Stiles opens his mouth to say something, but his phone vibrates in his pocket. He fishes it out of his pocket, and he smiles softly to himself to see that it is Scott. "It's Scott isn't it?" Derek says, smugly.
"Yes, shut the fuck up. I'm leaving." Stiles says, and Derek shakes his head fondly.
"Good luck with lover boy." Derek says, and Scott flicks his nose.
"You are the worst." Stiles insists, and he kisses Derek's cheek before grabbing his coat. "Text me, love you!" Stiles calls.
"Love you too, Mr. McCall." Derek says, as he shuts the door and Stiles doesn't even dignify that with a response.

Stiles finds Scott waiting for him at their apartment already on the phone ordering dinner. Being Scott's roommate has been the best, yet sometimes, worst decision of Stiles life.
It's one of the best because he genuinely likes spending times with Scott, and Scott is a pretty awesome roommate. They have almost the same schedule at school, and they work at mostly the same time so it isn't like they never see each other. What's not so nice about it is that Stiles has started paying more attention to things that Scott does. Like the way Scott only wears boxers to bed or the way he drinks the milk of of the cartoon. Which, if anyone else did it, would bother Stiles. Not when Scott does it; instead, Stiles finds it endearing.
"Hey, man." Scott says, and Stiles smiles at him while he moves to sit down on the couch. Scott hangs up the phone before walking into the living room to slump down next to Stiles with a loud yawn. Scott lulls his head onto Stiles' shoulder while they watch television. This isn't new for them, but Stiles loves it all the same. "What were you doing at Derek's?" Scott asks, and Stiles looks down to that he is frowning.
"Just watching the game while you were out with Kira." Stiles says, trying to keep the jealousy out of his voice. Scott may not the best at detecting emotions, but he still knows Stiles better than anyone. "Think he misses Braeden." Stiles adds.
"So he called his ex boyfriend to keep him company?" Scott asks, and Stiles shrugs his shoulders. He and Derek are in the past, and they've both moved on. Well, theoretically. Derek has Braeden and Stiles has a soul crushing unrequited crush on his best friend.
"It's not like that, Scotty." Stiles says, and Scott turns his head to nuzzle at Stiles neck.
"You stink." Scott says, and Stiles laughs in surprise. Scott joins in before he sits up to look at the door, and a few seconds the door bell rings. "I got Chinese. Hope that's okay." Scott says, and Stiles nods his head. They usually eat pizza, Chinese, or they try to find something in their fridge.
Scott grabs his wallet before paying the delivery boy, and bringing their food inside. Stiles shifts some on the couch to make room for the food, and Scott sits down next to him. Scott throws his legs into Stiles' lap, and Stiles stares at him mockingly before he sets his food on Scott's legs.
They eat in silence while they watch the game, and every so often Stiles or Scott makes a comment about the game. Scott is having trouble with the chopsticks, and he drops some food on his bare chest. Stiles laughs softly at his clumsiness, and he leans over to pick the food up between his fingers.
Scott grabs his hand before he can steal away the food, and eats it out of Stiles' fingers. Stiles feels his mouth fall open as he feels Scott lick around his fingers before pulling Stiles fingers out of his mouth. Stiles feels his heartbeat spiking in arousal as Scott watches him, and Scott's eyes darken.
Stiles isn't sure what to say, and Scott intertwines their fingers. "Don't take my food." Scott whispers, and Stiles scoffs in amusement. He isn't sure where this is going, but he wants to find out.
"Sorry." Stiles whispers, and Scott smiles at him while he pulls Stiles closer to him and Stiles lets himself be led closer.
"Your heart is racing." Scott whispers, and Stiles shallows thickly. Scott has dragged Stiles completely on top of him, and Stiles is breathing heavy. Scott runs his warm hand over Stiles' chest to feel his wildly beating heart under his hand.
"You make my heart race." Stiles admits, and Scott grins dimpled at Stiles. Stiles moves until he is straddling Scott so that he is more comfortable, and Scott moves the hand that is not holding Stiles' onto Stiles' back. Scott runs his fingertips just over Stiles' spine, and Stiles finds himself moving into the contact.
Scott licks his lips before he leans into kiss Stiles. It isn't what Stiles was expecting a kiss from Scott to be like. They bump noses, their teeth clash, and Stiles is so nervous he thinks he is going to faint. Eventually, they get it right. Their mouths mold together, and Scott eases his mouth open to kiss Stiles better.
Stiles doesn't hold back the moan that slips past his lips, but Scott shallows it. Scott lets go of Stiles hand to tangle one into Stiles' hair, and the other one he gently scratches at Stiles' back. "Scott." Stiles whispers, and Scott smiles at him
"Tell me what you want." Scott asks, and Stiles kissing him again. He isn't sure what he wants in the moment. For Scott to fuck him? To keep making out? To grow old with his best friend he's been in love with since he trully understood what love was really like?
"You." Stiles says, and he really hopes that Scott understands what he is trying to say. Scott grins wickedly at him, and he gently pushes Stiles back so that he can stand. Scott leans down to pick up Stiles with his super human strength, and he grins down to kiss Stiles when Stiles makes a squeaking noise of surprise. Scott keeps a firm grip on Stiles' hips while Stiles wraps his legs tightly around Scott's waist.
Stiles grips Scott's hair in his hand tightly, and he rocks his hips forward when Scott grabs onto his ass before dropping him on his bed. Stiles scoots back to make room for Scott, and Scott moves in between Stiles parted legs. Stiles drags Scott by his hair into another biting kiss, and Scott pulls away to run his lips over Stiles' cheek before doing the same to his neck.
Stiles knows what Scott is doing. He is putting his scent on Stiles, claiming him in a way as his and Stiles shudders a breath when he feels Scott drag his teeth lightly over his sensitive throat. Scott moves to suck a dark mark high on Stiles throat where he won't be able to hide it easily.
Stiles moans loudly when Scott rocks his hips against Stiles' hard cock, and Stiles can feel how hard Scott is on top of him. Scott is only in his boxers while Stiles is still fully dressed, and he seems to realize this before he tugs on Stiles shirt.
Stiles lets himself be undressed while Scott kisses him again, and soon Scott is pulling Stiles boxers down with his teeth. Stiles' cock springs free, and Scott sits up to trail kisses from Stiles chest down to his cock before he takes it in his mouth. "Scott." Stiles whines, and Scott pinches his thigh in answer.
Stiles stares at the ceiling, knowing if he watches then he'll come too quickly, and he feels Scott pulls his mouth off his cock. He looks to see Scott lick the precome off the tip while Scott palms himself. Stiles pulls Scott to him to kiss him, and he gracelessly pulls Scott's boxers down as fast as he can. "I have lube and condoms in my room." Stiles pants, and Scott nods his head before giving Stiles one last kiss before running as fast as he can to Stiles' room.
When he gets back, Stiles is laying on his back with his legs spread waiting for Scott. He jumps some when he feels Scott push a slick finger inside of him, but he welcomes it. Scott kisses Stiles' thigh while he works another inside, and Stiles just slowly mutters Scott's name. Scott finds that spot that has him seeing stars, and Stiles buckles his hips high in the air.
Scott pulls his fingers out of Stiles, and Stiles listens to the sound of Scott opening the condom. When Scott finally, finally, pushes his cock into Stiles' hole, Stiles feel complete. It's better than he could ever imagined, the way Scott cock stretches him deliciously, the gasps of air Scott makes that Stiles can feel against his skin. "Please, move." Stiles begs, and Scott kisses his shoulder ever so gently as he thrusts deep. Stiles cries out in pleasure as he scratches at Scott's back with every amazing thrust of Scott's cock inside of him.
Scott moves to rest his forehead against Stiles' as he pants into Stiles' mouth as he moves faster and faster. "I love you." Stiles cries as Scott hits his prostate.
"I love you too." Scott whispers, and he reaches down to stroke Stiles dick as his thrusts get sloppy.
"No, Scott. I really love you." Stiles whimpers, and Scott doesn't say anything he just kisses Stiles filthly. Stiles comes when Scott runs his thumb over the tip of his cock, and he cries out Scott's name.
Scott comes with his mouth attached to Stiles' jaw, and he bites down but not enough for it hurt.
****
Stiles is still panting when Scott pulls out of him to throw away the condom in the bathroom, and he brings back a wash cloth to clean up Stiles. Scott slips naked under the covers, and Stiles turns over on his side to look at him.
Scott pulls the covers over Stiles, and he slips his hands under the cover to run across Stiles' entrance. Scott slips just two fingertips inside Stiles again, he just wants to be close to Stiles, and Stiles sighs in containment.
Stiles feels his eyes grow tired, and Scott leans forward to kiss him. Stiles kisses him back, and Scott drags his cheek over Stiles' like he did before. "I love you." Scott whispers into Stiles' hair, and Stiles grins as his eyes close.
"I love you too." Stiles mutters, and he closes his eyes.
He knows that Scott will still be in his bed in the morning.
