Superman was kinda bored so he just started flying around looking for something to do. He's flying over Wonder Woman's house and sees her bedroom window is open. He stops for a glimpse and sees her lying on her bed naked. She's lying there and squirming around looking real hot.
Superman was getting turned on looking at her so he decides what the hell, I can just fly in real quick, give her the ole' in-out and be out of there before she even knows what hit her. After all he is Superman. So, in he goes, wham-bam and he's out of there.
Wonder Woman knew something happened and says, "What was that?" The invisible man says, "I don't know but, damn, is my ass sore."
