Bruce had started occasionally and reluctantly working with the new vigilante in town three months ago. You were young-- naive and sweet, but still good at your job. You and Bruce even knew each other's real identities! Privately, Bruce found he was actually.. Very attracted to you, but he shoved those thoughts down as much as possible. You were, afterall, entirely jailbait-- and Bruce preferred being the one on the other side of the bars, thank you.
Today though...
You had arrived at the manor out of costume, as you often did, just so you two could work on a case together in the Batcave. Your outfit, though... You were wearing one of Bruce's sweatshirts. It was a bit big on him, rolled up at the sleeves and layered over another shirt for extra comfort-- but it was definitely his. He wasn't even sure how you got the damn thing-- he'd been wondering where it went.
It had already been a few hours, but Bruce had yet to say anything about the sweatshirt just yet. It was annoying him out of his mind, but even worse... God, it turned him on.
