Treacherous Affairs

"Come on, she's never even going to know." Isaac said as he and Scott sat surrounded by books at his kitchen table.

"Isaac, no. Seriously, this is my kitchen." Scott said, shaking his head.

"So? We've done it in Derek's kitchen."

"Yeah, that's Derek's kitchen, where he does god knows what else. This is my kitchen; I eat dinner here with my mom." Scott hissed, pretending to read.

"Oh come on, where's your sense of adventure?" Isaac waggled his eyebrows and Scott shook his head without looking up.

"She could get home any time." He said.

"And we can hear for like a mile, plus maybe it's time she found out." Isaac managed to sneak that one in there and Scott looked up with a stern face.

"Not like that."

It had been just over two months since they had first got together and Scott was still cautious about telling his mother. She could handle him being a werewolf so why wouldn't she be able to handle him being in love with another guy? Isaac didn't know why he wouldn't tell her but he tried not to push the matter too much. He knew that they were going to have to say something at some point.

"Don't you love me?" Isaac pouted out his bottom lip and Scott let out a huffing sound.

"You know I love you, that doesn't mean I have to just blurt that out to her."

He knew that Scott loved him; of course he knew that, he said it enough. He was just a little cranky that he couldn't tell her about them. Granted, if Isaac's dad was around he wouldn't be rushing off to tell him, but Scott's mom was different.

She even let Isaac stay there for a while when he was sick of living with Stiles and Derek, who had no regard for the other inhabitants of the house.

Either way he was going to let it slide, again, because they had been at school all day and studying all afternoon, and he had plenty of time to convince Scott later.

"You want to go upstairs then?" He raised an eyebrow and Scott tried to hide his smile as he looked up from his book.

He tossed it onto the table and they both scrambled away and up the stairs to Scott's bedroom. They had barely made it through the door before they were tumbling back onto the bed in a tangle of limbs.

Isaac grabbed Scott by his wrists and pinned him back, grazing his teeth over his jaw line and ran his tongue over his bottom lip. Scott bucked up with his hips and struggled to get out from under Isaac, not enough to actually make a difference.

"Hey, who said you could do that?" Isaac growled, his lips slowly caressing Scott's neck.

"I didn't think you'd mind…" Scott gave another few bucks; grinding their hips together and making Isaac bite his lip.

"You want to be in control, get on top." Isaac smirked and Scott laughed.

Isaac pushed his shirt up and licked him from his navel to his sternum, pausing only to pull his nipple in between his lips, causing Scott to let out a low groan. He flicked his tongue back and forth and Scott parted his lips and exhaled heavily.

"God you're hot…" Isaac whispered and Scott grinned.

"Don't…" He panted.

"You are…" Isaac said as he shimmied down Scott's sweats and took a hold of his solid extended cock, and gave it a few short tugs.

Scott inhaled sharply. "And you're way too good at that."

"Tell me what you want me to do then." Isaac improvised and Scott smiled.

"I thought you were in… oh… in control…"

"Well I know what I'd do to you… if you want…" He felt Scott tense up a little and hoped to god he wouldn't pull away and make him stop.

"Uh… this, this is good… actually I'd rather you put your mouth to better use." He said, giving Isaac a sensual grin.

"I can do that." Isaac said, slightly disheartened but not enough to stop him.

He pressed his tongue flat against the base and slowly slid it upwards until he was swirling it around the tip. Taking it into his mouth he wrapped his hand around him and gave a few pumps as he slowly sucked on the head.

He pressed his tongue against the tip as he takes more of him in.

"Oh Fuck –" Scott said, lifting his hips to give Isaac even more.

Isaac couldn't help letting out a groan as he took Scott's cock all the way to the back of his throat and Scott let his toes curl at the feel of it.

Isaac's hands reached around to grab Scott's ass cheeks firmly, using them to pull his hips into him, slamming his own lips down until they couldn't go any further. He reached into his own jeans and took hold of his cock as Scott gripped his fingers in his hair.

Pulling back Scott sat up until they were both on their knees. "Let me take care of that." He said huskily and reached into Isaac's jeans, taking his cock in his hand and rubbing his thumb in the hot sticky pre come on the head.

Isaac grabbed Scott tightly by the waist and buried his face in his neck. He took his hand and brought it back to his shaft so they were both pumping one another furiously. Isaac lifted his chin to kiss Scott through his laboured breathing. Their lips were pressed together but it was hardly a kiss, more the sharing of breath, the intimacy was undeniable.

It didn't take long for them to reach climax, almost simultaneously before falling back beside one another in a hot mess. Scott smiled in his elated state and Isaac reached out to take his hand, lacing their fingers together.

"You know, we should get back to study." Scott said.

"You can't be that concerned about your grades, it's only week one." Isaac grinned.

"Hey, I promised my mom I would try."

Isaac sighed. "Yeah, okay then. Meet you down there?" He said as he got up to walk to the bathroom.

"Are… are you okay?" Scott sat up and asked with a tilt of his head.

Isaac gave him a grin. "Yeah but I think your mom's back and I need to clean up a bit."

Scott laughed. "Yeah okay."

Isaac headed out of the room and into the bathroom where he locked the door as he straightened himself up. He sighed to himself. He and Scott worked so well together but something was missing. They still hadn't made that final step to physically complete the relationship.

Isaac knows that it is a big step, especially for them, but he's starting to feel like Scott is ashamed. It doesn't help that he doesn't want to tell his mother either. Maybe it's something to do with Allison, he thought. He was pretty sure that she didn't know about them yet, that was just Boyd, Erica, Stiles and Derek. Jackson probably had a clue but he hadn't said anything and Isaac almost wished that it was out in the open.

Maybe that would make Scott accept their relationship for exactly what it was but at the moment, he seemed to be holding back.

That was not the case for Derek and Stiles.

"Oh God… Derek!" Stiles' voice echoed through the loft as Derek tilted his hips up and thrust himself even deeper into him.

His ankles rested on Derek's shoulders, his jeans pulled down to mid-thigh and Derek's only unzipped enough to do as he pleased.

Stiles had come back from school to find Derek doing sit ups. Well, he was hanging from the rafters doing air sit ups but still. It's not like it took much to get Derek in the mood, all it really took was one hot kiss and next thing he knew Derek was more than a few inches deep inside him.

"You're fucking amazing…" Stiles panted.

"You never shut up do you?" Derek said with a circle of his hips that made Stiles' groan get caught in his throat and come out in a much higher pitch.

"You… you love it."

Derek's lips made a crescent shape and he let out a growl as he pulled himself out and lay back on the couch for Stiles to lower himself back onto him. There were cracks in his voice as he felt Stiles' heat engulf him once more.

It was only a few thrusts of his hips before his stomach had tightened and the waves of pleasure ripped through him. Stiles only had to rub his cock against his hand once before he was coming too, making a mess of Derek's chest, not that he seemed to mind.

Had they been upstairs in Derek's giant comfy bed they may have laid like that for a while but Stiles climbed off and lay on his back on the floor, unable to use his legs completely yet.

"You know… if you do that every time I get home from school… it might make the idea of sitting through another day… bearable." He panted.

Derek's head may still have been spinning but he managed to raise an eyebrow and look down at him from the couch. "Might?"

Stiles chuckled. "Well your game might be slipping a bit Derek… yesterday was like… unbelievable but today was… well, I believed it." He smiled, knowing that it was stirring Derek up even if there wasn't any truth to it.

"I didn't even see you yesterday, remember?"

"Really? Oh… well it must have been a dream then. Still, dream Derek is upping his game, maybe you should too."

"You're delirious, and that's good enough for me." He said, standing up off the couch.

"That's all you're aiming for? Good enough? Hey, where are you going?" Stiles sat up, his body still tingling.

"To shower Stiles." He said as he walked towards the stairs.

"Wait up!"

They both headed up the stairs, Derek shutting all the possible doors in between him and Stiles, just to make it difficult. When he got to the bathroom he pulled down his jeans and kicked them to the side, groaning when he saw the pile that had formed on one side. It was a mix of clothes from Stiles and Isaac, and possibly even one of Scott's shirts and he wished he had gone to the ensuite rather than the communal teenager bathroom.

When Stiles made it in Derek gave him a sharp glare.

"Who said this was your laundry basket?" He said pointing to the clothes as he stepped under the hot water.

"Sorry, didn't think you'd mind." Stiles shrugged.

"You're a bunch of slobs, all of you. Erica was here for five minutes the other day and I could follow the line of crumbs from her potato chip bag to the kitchen." He grunted.

"Hey, hey, take it easy, I'll clean them up if you want." Derek narrowed his eyes as Stiles stepped into the shower. "Okay, clearly you want."

Derek turned his back on him, lathering up his hands with the bar of soap. Stiles tilted his head and he knew that something was on his mind. Obviously it had to be. Those clothes had been there for a week and he hasn't said anything. Stiles also found it strange that he had been exercising when he showed up, he had called first to tell him that he was about ten minutes away so he wouldn't have started a new work out. Not to mention he was working out in his jeans.

He's been strange for the last few days actually, Stiles thought. He put his arms around Derek's waist, almost expecting him to flinch away but he didn't, instead he gently caressed Stiles' arms until he was lacing their fingers together with a sigh.

"You know I didn't mean any of that stuff I said before, right?" Stiles asked, pressing his lips gently into Derek's skin.

"I know you didn't, I have no doubt in my ability to please you." He said, snapping a little but not letting go of Stiles' hands.

"So what's up then Mr Confidence?" Stiles asked with a smile and Derek shook his head.

"It's nothing alright?"

"Derek…" He said nothing, just stared down at their interlinked hands. "Derek you promised." Stiles muttered and Derek rolled his eyes, letting go to turn around and face him.

He pulled Stiles against him and held on to his hips as Stiles looped his arms around his neck. "You know I don't do this very well." He said through gritted teeth.

"Actually I've thought you've been amazing." Stiles shrugged, rubbing gently at the base of Derek's neck.

"You don't know any better." He muttered.

"True… but I know you're trying to talk to me more." He said.

"There's just… there's just a lot going on at the moment."

Stiles wasn't too sure what he meant, with barely any supernatural worries in two months things have seemed eerily calm and settled. He really hoped that wasn't a bad omen.

"Like what?" He asked.

"Would you calm down? Your heart is beating faster than it was when we were on the couch out there." Derek said, noticing the worry on Stiles' face.

"I highly doubt that."

"Stiles…" Derek grumbled.

"Okay, okay, what's going on Derek?" He asked, finally getting rid of his sarcasm and humour to get down to it.

"It's your senior year, you've got college coming… it just…" He grunted, absolutely hating this talking thing but he knew that it made Stiles happy so he tried. "It brings back memories is all." He said through gritted teeth.

Stiles nodded and pulled him in tightly, nuzzling into his neck and Derek did the same. Stiles knew that he was trying and he didn't want to push him to say any more so he just waited, his lips gently pecking Derek's shoulder and his thumb caressing the back of his head.

"It's been too quiet over the summer." He added and Stiles chuckled a little.

"Why can't anyone just be happy that we aren't fighting off deadly creatures for once? It doesn't have to be on the go all the time." He said.

"I know, it just seems like it's going too well." Derek said.

"Tell me about it." Stiles mumbled and this time it was Derek's turn to laugh.

"If you're going to get all sappy I swear I'll get out." He said.

Stiles looked up at him with the dopiest grin on his face. "I love you Derek." He said cheekily.

Derek's jaw set in a hard line and he rolled his eyes.

"Come on… you promised not to be such a sour wolf." Stiles smiled.

"No, I said I would forcibly get you to stop calling me that." He said.

"Come on, I won't say it again for the rest of the day."

"That's really the best I get isn't it?" Derek raised an eyebrow and Stiles grinned.

Derek shook his head and leant in to kiss his lips softly before mumbling quietly against them.

"I love you too."

Isaac and Scott walked down the stairs; all smiles. The chuckled to one another as they walked back into the kitchen.

"Hey boys…" They both jumped a mile when they saw her standing with her arms folded and hip popped staring back at them.

"Mom! God, you scared me." Scott said.

"Why, what are you hiding?"

Scott's eyes widened. "Nothing!"

"Listen Scott, if you want to go up to your room to play video games that's fine but can you at least clear off my damn table?" she said and Isaac heard Scott's heartbeat lower substantially, making him sigh a little.

"Yeah mom, sorry." He smiled.

"Isaac you staying for dinner?" Melissa asked.

"I would love to." He said, giving Scott a smile that made his ears turn slightly pink.

"Great, I'll grab out another plate and when you're done studying make some room for the food please." She said as she headed to the fridge to grab out some food for dinner.

"You want to finish this chemistry stuff then?" Scott asked Isaac.

He shrugged. "Not really but I guess we should."

Scott sat back down and fell straight back into it while Isaac made faces at having to study but he knew it would probably end up better for him anyway.

Isaac always loved having dinner with Scott and his mom, she made him feel so welcome and it was the closest thing to having a family that he could remember. After he helped her clean-up he and Scott went upstairs to actually play some video games. When Melissa walked past the bedroom door she poked her head through.

"Don't stay up too late, you've got school tomorrow remember." She said.

"Promise I'll try and sleep by eleven." Scott grinned.

"Make sure that you do." Melissa said with a narrowing of her eyebrows.

"Good night Ms McCall." Isaac smiled.

She gave him one in return. "Good night Isaac." She said as she left the doorway and headed for her bed room.

"How late is it?" Isaac asked.

Scott shrugged. "Late enough." He dropped his controller on the floor and stretched out with a yawn.

"Tired?"

He shrugged again. "I guess, more just not looking forward to school."

"Hey you're the one who committed to doing some actual study this year." Isaac said.

"I know but I promised my mom I would, after all this wolf stuff I think she just wishes I would do some normal teenager stuff."

"You realise that normal teenagers are lazy and don't get good grades because they're too busy being out with their friends, right?" He teased.

"Yeah, their human friends."

"You have human friends."

"Who? Stiles, Lydia and Allison?"

"Would you count Danny?"

"Maybe, I don't know, he's Jackson's friend and Jackson doesn't want him involved in werewolf stuff. I guess it's kind of nice to keep that separate from someone and not have to worry about it."

Isaac nodded. "Is that why you don't want to tell her about us? Because there's already been so much change?" He added slowly.

Scott turned to him with a pleading look and Isaac felt guilty again. "I do want to tell her." He said.

Isaac nodded without looking at him and Scott sighed. He crawled closer and rested his chin on Isaac's shoulder. He wrapped his arms around him and just stared into his eyes as Isaac tried not to look at him.

"I just don't want her to feel like everything is changing all at once you know?" He murmured and Isaac sighed.

He turned his head slowly and looked straight into Scott's big brown apologetic eyes. "Yeah Scott, I know."

Scott knew that he wasn't okay with it but he knew that Isaac wouldn't get mad or try to argue if he said he needed more time. He was wonderful in that way, in almost every way. He tilted his head to give him a soft peck on the lips before he nuzzled into the crook of his neck.

"I love you." He said.

Isaac kissed his ear and rested his cheek against Scott's hair. "I know that too." He whispered. "Let's just go to bed then." He said and Scott reluctantly pulled away, getting up to shut his door.

Isaac unbuttoned his jeans and kicked them off, leaving them lying beside the bed as he climbed in. Scott did the same, also pulling his shirt over his head before crawling in beside him.

He took Isaac by the waist and pulled him back into him, plastering their bodies together and slipping his arm around to tangle with Isaac's fingers. He kissed his shoulder blades through the thin fabric and Isaac closed his eyes, lifting their hands up so that he could brush Scott's fingers against his lips and taking one of his fingertips between his lips and giving it the slightest sweep with his tongue.

Scott smiled. "That's not going to help me sleep." He said and Isaac grinned wickedly.

"Hey, I said let's go to bed, I never said anything about sleeping."
