Superman was in the Fortress of Solitude. He decided to see what the other superheroes were up to.
He went to see Batman. When he got to Gotham City, he saw Batman was on a date as Bruce Wayne.
So he decided to check on Aquaman. When he got to their cave, he saw Aquaman & Minnow playing Twister alone.
Superman decided 3 would be a crowd so he went to see Wonder Woman.
When he got to her apartment, he saw through her window, that she was on the bed, disrobed and legs apart.
He watched for a moment then thought to himself
"It has been awhile since I've had sex maybe...no I shouldn't".
Then the more superman looked the stronger the urge hit him.
"I'm faster than a speeding bullet. I'll be done and gone before she'll notice".
He disrobes, flies in, haves sex & was gone in a blink of an eye.
Wonder Woman look around and asks
"What was that?!" The Invisisble Man said
"I don't know. But now my ass hurts like hell!"
(I'm pretty sure there are other versions of this joke. This is one that was told to me.)
