Sitter for a teen m/f story

[Guest Guestlooker]

Looking for a story, obviously. Its a teen m/f story. Female babysitter gets called to a trailer to watch a male teen. He’s not happy. He has a thing where he shows off for another girl in the trailerpark or who lives nearby, but she never shows anything in return. He later faps in the shower and the babysitter starts getting all hot and heavy. She later seduces him and they fuck. 

Hoping to find it again, appreciate any help.

I feel like I've read this, probably a long time ago, but I couldn't tell you where I saw it.
