Bruce led Wanda to the Batcave. She was astonished how big it was, and how many rooms there were. She looked in one room, and saw a room filled to the brim with trophies. She was in astonishment.
Bruce started walking again, and Wanda followed, thinking he was leading her somewhere. He walked to the end of a long hall, and pressed a button on a keypad on the wall. The doorway swung open, revealing an enormous bedroom the size of the living room.
"When you were asking me those questions before, were you serious? Are we a thing now?" Batman asked. He had taken his suit off, and was slowly unbuttoning his shirt.
"Of course I did, Bruce. You've been nothing but kind to me since we met," she replied.
"That's not something I would expect Deadpool to say. But it's very nice nonetheless." They didn't notice it, but they were right next to each other now. Holding hands even. Their faces were, like, two inches apart.
"Come here Batman," Wanda said. She grabbed him close and kissed him. Like, a real kiss. FRENCH KISS even. On the lips. Bruce had completely removed his shirt by now, tie and all, and was in the process of removing his pants. Wanda was wearing a bra and also removing her pants. It's a pants fiesta!
They got on the bed, the feeling of ecstasy still fresh. In nothing but underclothes now, they began removing THOSE.
"Are we going to regret this tomorrow?" Batman asked, completely void of clothes.
"I don't think that's possible," Wanda replied, also sans clothes.

and you know what happened next. :)
