Prompt 7: Cosplay
"I'm not going to wear that," Derek said, adamant as he pushed away the costume that Stiles was holding out to him.
"But, if we're going to fit in at the convention, you know, to get the skinny on what new evil seeks to set itself up in Beacon Hills, we need to dress the part," Stiles said, not for the first time. He was very proud of himself for being able to keep the whine out of his voice, and for not flinching at Derek's growled response.
Free Reader Tip #8: Werewolves are extremely stubborn creatures; you need to be very persistent and sneaky to get them to do what you want. Really, to get them to do what you know is best for them. This will take time. Don't give up hope. Especially when you know you're right, and your werewolf knows that you're right. Pride plays a big part in all of this. Pride and straight up pigheadedness.
A little more cajoling and promises that no pictures would be taken, and Stiles managed to get his werewolf into the costume. Derek made for a rather sexy looking, old-school Batman if Stiles did say so himself. And, as Derek was remaining pouty and put-out about the whole thing, eyeing the bat gloves as if they were minions of Hell that would suddenly come to life and strangle him, Stiles was the only one noting the sexiness of the whole ensemble and wishing, a little, that he hadn't made that promise to his dad, and Derek, about no sex until he turned eighteen.
The minute he did turn eighteen, he was definitely going to make Derek suit up, and have his way with the Bat. Na, na, na, na, na, na, na, na, Batman!
