"If you're not up by breakfast tomorrow, you're going to school without breakfast" Peter told Stiles as he saw him at his computer, it was now 11pm.
"Okay mom" Stiles answered,
"I am not your mother" Peter groaned out,
"no, you're not but you're acting like it" Stiles said. Mr Stilinski laughed,
"he's right you know, you're acting like a mother. Now come on mom, let's go to bed" Mr Stilinski said taking Peter's hand and leading him their now shared room.
"I meant what I said Stiles!" Peter called out, Stiles sighed, shut down the computer and went to bed.
Later that night Isaac snuck into to Stiles' room and was about to wake him up when he heard a low growl and the lights turned on, Stiles woke up. Isaac looked up ready to defend himself and Stiles,
"there's a bed in the guest bedroom, go to sleep" Peter told Isaac.
"He can sleep here with me" Stiles said and lifted the covers for Isaac to get in,
"any other pups that get in here through that window are to go to sleep, understood? And yes that does include my nephew" Peter told them as he closed the door and went back to bed himself.
"What was it?" Mr Stilinski asked as Peter got back in bed,
"Isaac sneaking in through Stiles' window. I told them to go to sleep and if any others sneak in through that window, they are to go to sleep too" Peter told him, hugging him and burying his nose into Mr Stilinski's neck. They both soon fell asleep. Peter awoke at 5am, got ready, went downstairs and started on breakfast.
Mr Stilinski woke up half an hour later, took a shower and got into his sheriff uniform and started towards the kitchen. He stopped at Stiles's door and knocked loudly "wake up" he said and continued his way to the kitchen, he kissed Peter on the lips and heard giggling,
"they do look good together" Allison told Lydia.
"Told you so" Lydia said and let out a yawn,
"why are we here so early grandma?" Erica asked Peter, he let out a growl.
"I'm not your grandmother, I established that last night with your mother" Peter said, the Sheriff just raised an eyebrow.
"Did I miss something here?" he asked, Derek looked at him,
"Stiles tends to mother them. Just like my uncle seems to be mothering Stiles, so they see Stiles as their mother, making you their grandfather, Peter their grandmother, and me their father" Derek explained.
Mr Stilinski nodded and just then Stiles and Isaac walked in,
"when were you going to tell me I was a grandfather?" he asked Stiles, Stiles let his mouth fall open. As soon as he composed himself, he looked to Isaac,
"say good-morning to your grandparents and father." Isaac looked at Derek who just nodded at him,
"morning grandpa" Isaac told Mr Stilinski and hugged him then did the same with Peter, or at least tried to.
"Morning Der, kids" Stiles said, hugging Derek. As Stiles opened his mouth to say something, Derek interrupted him,
"they already said morning to the adults" Derek told him. Stiles smiled at his kids, "good puppies" he said and sat down next to Derek, while Isaac sat next to Erica.
Mr Stilinski smiled at his new family as Stiles got up from his seat and helped Peter with setting plates with food in front of the others. Peter got the glasses while Stiles set the milk and juice at the middle of the table, they all ate breakfast. After breakfast the kids helped clean the kitchen, Mr Stilinski left for work and soon all the kids left for school.
