My little sister is a really pretty girl and she gets dick pics all the time from annoying boys, so being the girl she is, she started using them as blackmail. She now has about 30 boys doing her bidding because one stepped out of line and she got someone to print out 500 copies of the photo and mailed it to his family.
My sister is 16 and she’s running a black mail Mafia. She’s going places.
Your sister is a budding felon and also probably a terrible person. This isn’t cool when men do it to women. It’s also not cool when women do it to men.
It’s not cool for anyone to do it to anyone. Seriously.
