A/N- Just to warn you, there is some rude stuff in this chapter!

On the day of the barbecue the Betas were psyched up for the match, despite knowing they stand very little chance of winning. The Alpha house was made up of the best sporting jocks and even though the Betas had some star players like Danny, Isaac and Scott they were still disadvantaged. Nevertheless that would not dampen the Beta spirit, plus there were loads of Sorority girls cheering them on, everyone had turned out to watch the game.

On the way to the game Stiles had received a text from Erica, 'Just heard Derek and Kate broke up!' Stiles can't help smiling as he returned his phone to his pocket and headed into the locker room.

Stiles and Derek were both captaining their houses, and they were both taking the match extremely seriously. At half time the Betas were only one goal behind matching the Alpha goal scoring prowess much to Derek's frustration. He could be heard yelling at the team from the other side of the field, while Stiles excitedly pumps up the team ready for the next quarter.

It was in the nature of the Alphas to be really competitive but they seemed to be treating it as a matter of house pride. With the scores almost level tensions were running high and little scraps were breaking out between the players. The referee was having a hard time controlling the game.

After the team talks the players run back to their positions on the field, on the way Jackson deliberately crashes into Stiles.

"Wow you're taking this very seriously Stilinski, we had a wager that you organised this just so you could gawk at us in the locker room!"

A few Alphas laugh at Jackson's lame joke; Stiles has to hold Scott back to stop him punching Jackson in the face. The other team members start to run over to the commotion, spoiling for a fight.

"Wow you caught me Jackson, you freaking irresistible, like gay guy catnip!" Stiles replies.

"Leave him Jackson, he's not worth it." Derek calls to his team.

Stiles looks at Derek, so hurt that he doesn't call Jackson out, he had stupidly believed they were friends. But Derek words hurt more than a thousand comments like Jacksons, he tries to shake it off but just replays the look they shared over and over in his head. A look of distain, like he was something Derek stepped in.

He plays the part well in the next quarter, trying not to let what happened put him off his game. In the end the Beta's lose but not by much and the team are jubilant despite their loss. The plan was to head back to the Alpha house for a barbecue and drinks, but Stiles is in no mood to socialise. He makes his excuses to Scott, faking not feeling well so he can return to the Betas house alone. Stiles flops on his bed burying his head in the pillow, he would not cry not over Derek Hale.

"Stiles, Stiles! Open the door. I need to talk to you!" Derek bangs his fist on the door.

Stiles flings the door open in a rage, "No need to break the door down!"

"I'm sorry he shouldn't have said that to you..."

"You literally don't get it do you!" said Stiles stomping back into the house.

"Stiles, just stop...what do you mean?" said Derek following Stiles into the house. He tried to grab Stiles' arm but he shrugs him off turning to look him in the eye.

"It doesn't matter what that idiot said, I matters that you're captain of the lacrosse team, head of the Alphas and you didn't stick up for me and say something to those jerks...I thought we were friends!"

"We are friends, Stiles I'm so sorry, I should have said something, I should say at lot of things but I just can't seem to!" Derek tugs at his hair in despair.

"Say what! Stiles almost shouts then he adds quietly "Derek just say it, it's me, you can tell me anything. Why do you keep pushing me away, I don't understand you sometimes."

"I've fallen for you Stiles, It's driving me crazy, I can't stop thinking about you." Derek blurts out before he can change his mind.

Stiles looks stunned, Derek couldn't have said anything that would have shocked him more. He opens his mouth to speak and shuts it again. Derek had achieved the impossible, rendering Stiles speechless.

"Stiles?" Derek asks tentatively.

Without warning Stiles steps forward grabbing the back of Derek's head and kisses him. Derek seems shocked for a few seconds before he responds kissing Stiles back hungrily. Stiles feels Derek's tongue against his own as the kiss turns open mouthed and sloppy. He smiles as he pulls back, breathless all he can say is 'Wow.'

Derek beams, "I know...wow!"

Derek initiates the kiss this time, before he knows it he has Stiles pressed up against the wall, both of them panting for breath. Derek presses his hips against Stiles and smiles against his lips when he lets out a deep moan. Stiles pulls away, his hair a mess where Derek has run his hands through it, his lips are red and swollen from their passionate kissing.

"We should take this to my room." He pants still out of breath.

Derek grins as Stiles grabs him by the hand and leads him upstairs. As soon as Stiles shuts the door Derek pushes him up against it with his whole body, and attacks his lips. Derek grinds his hips against his spreading his legs wider with his own. Derek runs his hands under Stiles' t-shirt, a thousand goosebumps erupt on his skin at Derek's achingly soft touch.

"Oh my god." Stiles moans out as Derek attacks his neck, kissing and biting downwards. He steps back to drag Stiles shirt off, then goes back to kissing his chest, biting a nipple between his teeth. Stiles pushes him back dying to finally get his hands on those abs he's fantasised about for so long. He pulls Dereks t- shirt over his head, getting it stuck on his ears, his moves are no way as polished as Derek's. They both laugh as Stiles finally gets it off, flinging it across the room. He tentatively kisses Derek's pecks, Derek watching him wide eyed. Stiles kisses down lower and lower until he's on his knees licking Derek's delicious hips and pushing his jeans down as low as they will go without undoing them. Derek throws his head back letting out a low moan as he runs his hands though Stiles hair.

"Is this ok?" Stiles asks as he starts to undo Derek's buttons.

"Yes" is all Derek can manage he's holding his breath, nervous but desperate for Stiles' touch.

Stiles drags Derek's Jeans and boxers down his legs.

"Fuck" Stiles says to himself as he sees Derek's rock hard cock for the first time. He looks up at Derek who has his eyes screwed up shut. He gives it a few gentle tugs, looking up at Derek trying to gauge his reaction, not wanting to rush Derek into anything.

"Still ok?" This time he just gets a grunt in reply and when he takes as much of his cock as he can manage in his warm, wet mouth Derek's eyes fly open and moans loudly.

"Oh my fuck" He moans out thrusting his hips forward, almost choking Stiles on his generous length. Stiles puts his hands on his hips, taking back control. Using all his best moves he licks and sucks until Derek is a moaning mess within minutes. Stiles looks up, his big brown eyes full of lust meeting Derek's and it sends him over the edge.

"Stiles i'm gona..." Derek tries to pull back but Stiles just takes him deeper and he comes hard in his mouth.

Derek drops to his knees, his legs so wobbly they can no longer hold him up. He kisses Stiles "Thank you...that was...amazing."

Stiles grins happily, his own cock is still staining painfully against his Jeans desperate for any kind of friction. As soon as Derek has recovered enough he leads Stiles over to the bed and pushes him down his whole body weight on top of Stiles. He kisses Stiles gently at first but it soon turns heated, Derek rubbing against Stiles painfully straining cock; he is already semi hard again.

"Wow you have a lot of stamina."Stiles compliments.

"A year you remember? And I've thought about this a lot... but it's so much better." Derek grins.

Stiles beams proudly as Derek removes the last of his clothing, their cocks rubbing together as Derek gently thrusts against Stiles, giving him the friction he so desperately needs. Soon Stiles in writhing around in ecstasy, Derek taking both cocks in his hand still thrusting against Stiles' body, now slick with sweat. It doesn't take long before Stiles comes with a ragged gasp over both their stomachs, Derek following Stiles' lead by less than a minute.

After they clean up they lay side by side still breathing heavily, "I feel like jelly." Stiles says sleepily.

Derek pulls the cover over them both and cradles Stiles in his arms, pulling him against his chest. They dose for a little while both to sleepy and satisfied to talk or move. When they awake from their dozing, Stiles turns to give Derek a lingering kiss.

"Stiles about earlier, I'm going to say something to those guys, they can't get away with that. I won't have anyone talk to you like that; I just got so carried away with the stupid house rivalry. I want you to know I'm so sorry."

"Thanks but it really doesn't matter to me after what just happened, anyway I have a better idea, come to the winter formal with me? As my date?"

Derek gives a nervous look.

"Unless that's not what you want I just thought, oh...was this just a one time thing?"

"No way!" Derek hastily interjects "I would never do that to you...I want everything with you."

Stiles smiles "So you'll be my date?"

"Yeah, of course, I'm just nervous of how people will react to this; I mean it's going to be a surprise."

"Yeah well it surprised me!" Stiles laughs.

"Stiles what are we now?" Derek wonders.

"Boyfriends? I mean if you want?"

"Yeah, I want that." Derek smiles shyly.

"Until the formal which is what three weeks away, let's just keep this to ourselves, I don't want to pressure you, let's just take this slow and get used to it being just me and you." Stiles kisses Derek again but before it can turn into anything more they hear the door open and a rabble of voices below.

"Crap, ok out the window, my secret lover!" Stiles said pushing Derek out the bed.

Derek laughs as he races around the room trying to find his clothes. They share a chaste kiss as Derek disappears out the window, just in time as he hears Erica calling him from downstairs. He pulls on his sweats and heads for the kitchen.

"Hey" he greats the Beta's that are back from the game.

"Where did you disappear to?" Isaac asks as he and Erica follow him into the kitchen.

"Oh you know, had stuff I needed to do and..."

"Stiles Stilinski, you had sex didn't you!" Erica shouts out.

"What, no, how could you know that!" Stiles can't cover up quick enough totally shocked and bright red at Erica outburst.

"You have sex hair, swollen lips and if I'm not mistaken stubble rash!" Erica points out the offending areas.

"Shush! It's supposed to be on the down low!"

Isaac looks completely miffed.

"Was it...him?" Erica asks with a huge grin.

"Yeah." Stiles can't help it as a huge grin spreads across his lips.

"Who, what?" Isaac asks.

"Shush!" Comes from both Stiles and Erica.

Isaac just goes back to looking confused.

"Was it...good."

Stiles grins again

"I knew it, you can't keep that 'I just got laid grin off your face!'" She replies excitedly.

"Big?" she asks with a cheeky wink.

"Erica!" shout Stiles and Isaac.

"What, I have to know!" Erica looks mock scandalised.

Stiles grins again as he returns the juice to the fridge.

"Knew it!" Erica shouts, just as Danny and Scott walk in.

"Knew what?" Scott asks "Oh hey man, where did you get too?" he asks Stiles.

"Oh I had too..."

"Have sex apparently?" Isaac interjects innocently.

"Isaac!" Stiles moans as Erica bangs her head on the fridge.

"It's supposed to be on the down low!"

"Opps" Isaac laughs.

"Wait you had to go have sex, what?" Scott asks always a little slow on the uptake.

"Wait was it?" Danny gestures at Erica in a totally unsubtle move.

"Yeah it was! And amazing and huge." Erica blurts out.

Danny looks like all his Christmases just came at once.

"Stiles you old dog, can't believe you cracked him!" Danny congratulates with a slap on Stiles back.

"I never said any of that!" Stiles look mortified.

"What is going on!" Scott looks blankly around at everyone.

They all laugh at Scott's expense.

Stiles puts his arm around Scott and steers him into the living room.

"Time we had a little talk, about the birds and bees." Stiles said.

When Stiles has finished an exhaustive conversation where he was pumped for details about his encounter with Derek he returns to his room to find a text from Derek.

'Can't stop thinking about you. X'

Stiles grins and replies 'Me either, we should do that again really soon x'

Derek replies instantly 'Can I climb in your window tomorrow morning? X'

'You can come in anytime ;)'
