Derek came out of his astonishment when he heard Isaac screaming and he went to stop his uncle who was going to spank his beta again.

"Peter, we are going to talk to him at home, not now."

Peter stopped his arm on the way to Isaac's ass. Derek looked at Isaac who was looking at him with fear, as if he expected Derek to burst and break some of his bones, but the alpha put him into a hug saying that he had worried them. They leave of Deaton's and went to the apartment. Isaac looked at Peter with of fear and hate, it was years since anyone had spanked him, his father had done it when he was younger but one time or two.

- Okay, you go to your room Isaac, and have a shower, we are going to talk later. And you Peter, with me to the kitchen.

Derek said calmly. Isaac went up the stairs and the sound of the bath water began to be heard.

- "spanking?" He asked incredulously to his uncle.

- What? It is what I would have done if you had put your life in danger.- he replied serenely. Derek glared at him.

- I'm old for that, so is he.

"Well, tell me, old man, what are you going to do to make him obey before he's dead?"

- I can't spank him, I have no right.

- He lives under your roof, you care about him, right enough. Go up and make sure that boy does not put himself in danger again or I will and then, I'll give you a spank for coward.

- Grrrr ... - Derek growled, he knew that his uncle was right

- Okay but, if he hate me then you will adopt it.

Derek went upstairs and found Isaac sitting on his bed with his head down and his pajamas on.

- Isaac - he called, Isaac looked up hoping to find anger on his alpha but he breathe when he anger wasn't on Derek's eyes.

- Isaac, you worried me today. What was happening trough your head?

- That ... that I am not a child so that you can't leave me locked here, I could help. - The rebellion sprang from his body.

- You're a child, if we leave you here is for your safety, look what happened.

- IF YOU HAD INCLUDED ME IN THE PLAN IT HADN'T, - he shouted, couldn't believe that Derek didn't understand him.

"Isaac Lahey, you won't raise your voice again to me. We have had this discussion already, you were not prepared to go, now come here, I will teach you what happens to the disobedients.

The rebellion vanished the moment he heard his full name. Derek was going to kill him, he was sure. He was going to break every single bone on his body. He was so focused on his fears that he didn't notice when Derek grabbed him by the wrist, lifted him off the bed and laid him over his lap.

PLAS. The first spank came down hard.

"Derek no." Isaac understood where the thing was.

- Oh, Derek yes, you decided to be a bad kid well, this is what happens to bad kids.

PLAS PLAS PLAS PLAS PLAS PLAS PLAS PLAS PLAS PLAS PLAS PLAS PLAS

A rain of spanking fell on Isaac's poor ass as he twisted, trying in vain to escape of Derek's grasp.

- You stop moving or I swear that I take off my belt. - Derek threatened. Isaac in a moment of frustration used his werewolf teeth and bit Derek's leg hard, realizing too late what he had just done.

- ISAAC, GET OFF, Derek shouted and Isaac visibly shrank into the alpha's legs. Derek pull of Isaac's ear and get his beta up.

- Don't bite me again Isaac.- he said while his other hand get down Isaac's pants and then unbuckled his belt. Isaac panicked.

Hi again! I'm going to post the last chapter as soon as I can. I was wondering if you would like a story like this but with the twins as principals. What do you say?
