Looking for an old story from Literotica, asttr or Kristen Archives

[Mailman]

Many years ago I stumbled upon a story. Something along the way of cheerleader in her room on the phone with a friend, when a dark entity / ghost takes her and uses her. As I recall there was a baton, bedpost, etc. Door was locked and mother desperately trying to get in to save her.

Any guesses on which story that might be? Haven't been able to look it up since then.
