"So. Where have you been?" The question came from one Derek Hale, alpha werewolf and current guardian of Isaac Lahey.

"Just hanging out with Scott and Stiles," he answered, taking off his sneakers at the front door. One of Derek's rules, he didn't want mud getting tracked into the house.

"Isaac Lahey," Derek's voice was warning, even if he was hanging out with Scott and Stiles, it was twelve thirty in the morning and an hour past his curfew.

"Y-yes?" His voice faltered, the tone of Derek's voice was scary. Isaac knew that even if Derek was royally pissed off at him, he wouldn't do anything to seriously hurt him as his father did. Still, that didn't change the fact that his alpha could be one scary dude.

"Care to tell me why you were hanging out with Scott and Stiles past your curfew?"

"Well. We just kind of lost track of time I guess, I'm sorry." He tipped his head down, avoiding eye contact with the man as he waited to get yelled at and worse.

Derek's arms folded across his chest, eyeing the teen in front of him with a strict look in his eyes "You know perfectly well how to look at your phone to see what time it is Isaac. Losing track of time is not an excuse and you know that."

Isaac's looked up, his lower lip out in a kind of pout, "But – uh.." He went to argue, but one look from his guardian made him clam up, "Yes Sir. I'm sorry." He apologized again, wanting to leave his spot from in front of the door, but also not wanting to risk moving either.

With a hard sigh, Derek shook his head before speaking, collecting himself "Alright, I want you in your room. Change into your pajamas and wait for me. Got it?" The teenager before him knew exactly what that meant. Derek heard a canine whine emit from the boy and a soft 'yes sir' before sulking past him and heading toward his bedroom.

Isaac shut the bedroom door behind, chewing on his bottom lip as he pulled out an old t-shirt and a pair of pajama pants from his dresser. He had known he should've left Scott's place at ten, but he let the other boys talk him into staying for a few more rounds of their video game. Then, before he knew it, it was 11:45 and 15 minutes past his curfew. Derek might have let it slide if he was half an hour late, but in the moment he had decided if he was going to be late, he might as be late and have beaten Halo. So, here he was, sitting on the edge of his bed in his PJs, waiting for Derek to come and sp- he couldn't even think about it. It was so humiliating, so childish, he hated to admit the fact Derek was about to punish him like some little kid. "Isaac." He jumped, taken out of his thoughts by the sound of Derek's voice entering through his mind.

"I really am sorry for missing curfew Derek, but I haven't in a long time. Can't you just let me off the hook?"

"I've told you a hundred times what happens when you break any of the rules, and letting you off the hook means letting you do as you please. And I won't let you get into your head that if you pout a little you'll get your way." Walking towards Isaac, Derek motioned for him to stand. Quickly, he was obeyed as Isaac reached his feet and waited. "What did I tell you last time you missed curfew?" He asked, sitting down on the bed after he removed a wooden hairbrush from his back pocket.

"But, that was almost four months ago! Please Derek!" Isaac went back into pleading again.

"I asked you a question Isaac, I expect to be answered," Derek's voice wasn't overly harsh, but it was firm enough to let Isaac know that he wasn't in the mood for any games.

"Y-you said that you'd s-spank me w-with that hairbrush," he eyes darted down to the object sitting by Derek's leg and then to the floor. "And that it would be," he paused for a moment, trying to form his words, "it would be bare." The boy had to fight the urge to plead with his alpha some more, but bit his tongue.

"Correct," Derek caught his ward by the arm and pulled him over his knee, hooking his fingers into the pants before him and yanking down until Isaac's milky white butt popped out ontp display. "Now, I want you to think about why you are here. I give you rules for a reason Isaac, and I expect them to be followed. You know by now that I will not tolerate disobedience from you, so. I want you to count aloud, you'll get fifteen. Ten for breaking curfew and an extra five because this is the second time you're being punished for this."

A shiver ran down the beta wolf's spine, the moment he was placed across Derek's lap he felt that surge of submission pass through him. Derek's own dominance was pulsing as he explained to him what was about to take place, his face burned red at the fact he was giving up his fight and accepting his fate. "Yes Sir," as soon as the words left his mouth a loud CRACK rang out in the bedroom. A sharp gasp came from the teen's lips when a pink oval shape was left on his backside. "One."

"Good," Derek praised the kid for listening to him, he knew it wouldn't take much for Isaac to listen. The kid was already still broken from the way he was raised, but Derek was determined to show Isaac the right way, and that punishment didn't mean abuse.

Despite the position he was in, Isaac felt a wave of pride when he was praised by Derek, a sense of happiness in him at the thought he had done something good and praiseworthy. "Two!" Isaac flinched when the second crack landed.

CRACK SMACK "Ah! Three! F-four!" he wasn't even half way done and he already stuttered, dammit. Derek caught Isaac's right leg when he kicked up in the air at the smarting smack that was delivered to his quivering bottom. "Five!" Isaac gripped at Derek's pants, trying his best to keep still, knowing if he squirmed too much he'd get a smack to the thighs. Those ones always did hurt the most too.

After another handful of Derek's brush falling onto Isaac's bottom, Isaac finally tried to dodge the attacks with full force. "ow! Oh! Derek!" Issac didn't really think about it before he did it, but his teeth sank into Derek's leg as an attempt to get away.

"Isaac Lahey, stop that this minute or else!" Derek thundered out, causing an immediate still in the wiggling and kicking and a release of pressure off Derek's calf.

An extra hard smack landed onto Isaac's thighs after a moment of the tense silence, "ah ah! Why'd you do that for! I stopped!"

"That's for causing such a ruckus in the first place!"

"I can't help it, it hurts!" Isaac's feet stamped in an attempt at a weak tantrum. "OWW!" Another slap to the thighs.

"And don't start a tantrum now mister! I know it hurts, but you don't try and bite me, you know better than that! Now. We were only on eleven, the two to your thighs do not count!"

"AH! But!" Another sharp smack, warning. "Twelve! Thirteen!" Derek's last smarting hit was given a bit more force, to let Isaac know not to try and argue any further. He felt the kid tense under his hold before slumping and whining softly. "Please finish up, it hurts." his voice was demanding and he wasn't trying to order Derek around. Instead, Isaac was simply pleading for the spanking to end quickly, he was at his whit's end and from the sounds of it, tired. Derek finished up with two quick falls of the brush, before hearing Isaac's voice "fourteen…fifteen…Please forgive me, I'm sorry I acted so poorly." After the words came out of his mouth he began to cry earnestly, his once milky white behind was now a pulsing red tomato.

"You're forgiven Isaac, now I think its off to bed with you," his voice had lost his edge as he righted the boy's pants, eliciting a small whimper of discomfort. "Come on," Derek helped him stand before patting his head affectionately. "Is my pup alright?"

Isaac's face heated up a bit, but nodded anyways. "I'm okay, it ju-hic-st that it, hiccup, really smar-hic-ts." He hiccuped out before leaning his head against Derek's shoulder.

"I know kid," Derek ran a hand through Isaac's hair, the motion calming to the boy before him, before helping him into the bed and pulling the covers over him.

When Derek turned and walked to the door, ready to leave and head to bed himself he was surprised when he heard Isaac mumble in embarrassment "D-Derek?"

Turning, he saw Isaac had sat up in despite the discomfort it brought his throbbing backside and was blushing a deep shade of red as his eyes stayed cast down onto his comforter. "What's wrong Isaac?"

"Uhm, it's just I was wondering," He began to kneed at the blanket in front of him, "if you would stay…in here until I feel asleep," he looked up suddenly. "But you don't need to! I don't care either way! It's just a thought! You can go if you want though, it doesn't matter to me!" Obviously, the request was hard for Isaac to ask, and the importance of it was there despite Isaac's embarrassed rambles.

"I'll stay, move over." Derek pushed Isaac so he was against the wall, giving Derek more room to jump in bed beside the boy.

"Thanks…" Isaac mumbled again, but now he had his face buried in Derek's chest, the scent of his submissive side still emitting off of him as Derek rubbed his back soothingly.

Soon enough, Isaac had fallen asleep and Derek decided to sleep there as well, not wanting to risk waking the sleeping teen.
