Stiles was still overwhelmed by the amount of contact, and the enthusiasm involved. This time last year he’d had probably- well, not killed, but he’d certainly have done something ridiculous and dramatic to have Erica pressed against him. Or even Isaac. But now he had Derek and...this was his life. He’d expected the two of them to maybe follow Derek, but they remained with him, Erica pressed against his side, arms wrapped around him, and Isaac content to just touch Stiles’ hand and arm.
Boyd crept behind them, heading for the kitchen quietly to see Derek, just to bump against him, gently scent, a little less handsy than the other two-
“Do we get to keep Stiles or are you going to want him back when the movie starts?” Erica yelled whilst Isaac moved ahead to try and get first dibs on a film. “No more Marvel!” She added, hugging onto Stiles’ arm. “Find something normal.”
“What do you mean normal?” Isaac asked. “Like Mad Max?”
“No! Like a regular movie.”
“Gimme a clue, woman!”
“Mom, Isaac’s yelling at me!” Erica grinned at Stiles, rubbing her cheek against his shoulder.
Stiles snorted, his cheeks flushing. “No, don’t do that.”
“But you are our mom! Derek’s our dad-“
“That makes you and Boyd siblings, so gross,” Isaac returned, holding up the Star Trek movies.
“Lame,” Erica replied.
“Okay, you choose, I give up,” Isaac replied, stepping away as Erica bounded forward again. He sat himself down on the sofa and Stiles, after a moment of deliberation, reached out and ran his fingers through Isaac’s hair. He’d seen Derek do that to them, and it seemed safe. Isaac made a soft noise in his throat that made Stiles feel equally pleased and oddly protective at the same time, and he continued to pet him gently, perhaps lavishing a little more attention on his than was strictly necessary, but it was making Isaac happy.
He jumped slightly when Boyd’s large hand rubbed against the back of his neck, before he sat down beside Isaac and watched Erica reorganise all of Derek’s movies.
