An idea, which wouldn't leave me alone. Set after season 2. AU, because Sterek and Sheriff knowing about supernatural.
WARNING: Two boys kissing.
Stiles made a pleased noise as Derek pressed him down on the couch, claiming his mouth in an intense kiss. The werewolf gently lowered his body on top of the boy's, keeping himself propped up on his elbow placed next to his head. Stiles' hands started to wander across his back and shoulders, eventually finding their way under his shirt as their make out session got progressively longer.
That's how the Sheriff found them a few minutes later.
"Jesus, again?!" the Sheriff groaned. It wasn't the first time he walked in on them making out (and he made sure it will be just making out until Stiles turned eighteen), but he hoped to never see them doing it on his couch again.
Derek lifted his head to look at him in surprise, clearly put off at not hearing him coming, and pulled himself away calmly. Though his stubble couldn't quite hide an embarrassed blush on his cheeks. Stiles craned his neck to throw the Sheriff a wide smile.
"Hi, dad," the boy chirped. "How was your day?"
The Sheriff raised his eyebrows, "Not as good as yours, I see."
"Maaaybe," Stiles drawled, getting up off the couch. "Dinner is ready. We were just waiting for you."
"How thoughtful of you," the Sheriff snorted, heading to the cabinet to put his gun and badge away. "You could make sure I didn't walk in on you, instead."
"You like being reassured we're keeping to our promise," Stiles replied from the kitchen.
"I'm not!" The Sheriff denied. "I know Derek is a good man and he will never take an advantage of you," the Sheriff smirked. "You on the other hand..."
"Hey!" Stiles cried indignantly.
Derek and Sheriff chuckled.
They sat at the kitchen table and started eating.
"So," Stiles started after a few minutes. "We want to warn you, that things may be a little weird for a while."
"What does that mean?" the Sheriff asked, concerned. "It's something supernatural? Are you in danger?"
"No," the boy shook his head. "Nothing like that. You see, the pack..."
Earlier that day...
The pack, sans Derek and Stiles, gathered after a meeting to discuss a very pressing matter.
"I can't take this anymore," Jackson complained. The rest nodded their heads in agreement.
"This sexual tension between them is going to kill me," Erica groaned.
"You're the one to talk," Isaac grumbled. "You're not the one who has to live with him." That gathered a few sympathetic looks and pats on the shoulder.
"We need to do something," Lydia decided. "Make them see how into each other they are."
"How?" Scott asked.
"We set them up," Allison light up, catching on onto the plan.
"Exactly," Lydia smiled. "We just need to throw them together outside of the life and death situations."
"Like a date?" Boyd checked.
"Yes!" Erica grinned. "I just know a thing..."
Their discussion proceeded for the next hour, each of them getting frustrated at the rest as their idea was rejected by the others.
"Okay, that's enough!" Scott shouted finally. "Why won't each of us try their own idea and if it won't work, the next person has a chance?"
"I agree," Lydia said, pulling a notebook and a pen from her purse. "We will draw a number. The number will point out person's place in the line. That fair for you?"
Everyone mumbled their agreement, got their number and left to plot their date for the Alpha and his Human.
None of them saw the red eyes shining from the shadows.
"Jesus Christ," the Sheriff rubbed his palm across his face. "They don't know you two are together?"
"Right?!" Stiles threw his hands up in exasperation. "You think at last werewolves with super senses would notice!"
"It's not like we're hiding it," Derek frowned. "Idiots."
"Why won't you tell them then?" the Sheriff asked.
"We will have fun on our own!" Stiles exclaimed, his face lighting up with sudden excitement. "We're going to rate their ideas and choose the best!"
The Sheriff looked at Derek, hoping for some rational input in the crazy.
The Alpha shrugged, "I'll make sure nothing bad will happen."
Stiles kissed him enthusiastically. The Sheriff sighed into his food.
