I can't stop masturbating to this one friend

I have a friend from a while back who I haven't been able to stop masturbating to these past few months. She uploads some of the sexiest videos and pictures on social media and I can't but help get a hard on for her and stroke one out.

Wish I could tell her or one of our old mutuals but I don't keep in contact with em and it might be weird lol. But just stroking to her is so nice, anyone else masturbate to old friends?
