Sterek AU: Ever since he was a kid Stiles has dreamed about being a baseball player. He eats, sleeps and breathes baseball, and the thing he’s always wanted more than anything is a chance to play alongside his idol, Derek Hale. Once they’re finally on the same team Stiles and Derek clash over the fact that Stiles can’t seem to take anything seriously, and Derek can’t seem to take a joke. The only thing they can agree on is baseball. 

Stiles:  Derek put me down!

Derek:   How about no?

Stiles: Derek! For the love of— put me down now, or I swear I’m going to end you! To your end!

Derek:   I turn my back for five minutes and you manage to get yourself possessed by a Japanese fox demon and mated to a coyote. Don’t think I’m letting you out of my sight any time soon.

Stiles:  DEREK!!!
