14 years old having sex with 17 year olds and up

So my "friend" is having sex with older guys and her parents don't know. My "friend" is 14 years old but she lost her virginity at 13. My "friend" is starting rumors about me saying I sent nudes which I really don't she's the one who send pics of herself in the shower every night that's also child pornography. I wanna get even by snitching on her she thinks she so tough but let's see how tough she is when I tell her parents she fucking 17 year olds she even invited a 21 year old guy over to fuck her. She's literally being jail bait and no she's not being raped she wants it she throws herself out there. Like she did me so dirty by saying I sent nudes but when really I didn't she wants to play dirty so can I. And I have so many secrets against her and she has nothing on me. I'm just wanna reach her a lesson. 
She's telling anyone that will listen I'm sending nudes.
