No.

"No, I cannot forgive you. I'm afraid I'll have to tell Superman that you were rude, did a poor job of protecting his city, and that you're a slut." You tell her while mentally making sure that she fears her cousins judgement.
"Oh, please don't do that!" She begs from her knees, "I'm not usually such a slut, I just couldn't help myself for some reason! And I think I'm doing a pretty good job with the city, but it's stressful, that's why I was rude. Please don't tell him. I'll do anything!"
"Fine, I have a few things you could do." You pull out your phone and take a picture of her cum covered face. "But if you do anything wrong, this gets sent straight to Superman." You show her the picture and she looks worried.
"I'll be good, I swear."
