This could work on F/X.
Johnny can be played by Jackie Earle Haley.
His wife would be Paula Malcomson
Capri can be played by any random 23 year old ex disney bitch.
Dayton Callie could be the Wolf.
Johnny would be a total head case. It would show his dual life and the control he holds over these poor girls. The first episode would start with him picking up Capri the whore and making her sit in his lap. The middle would be showing him at home, with the wife and kids and ideal life and no one is wiser. A Few scenes of him having car sex and gaining control over capri. The end of the pilot is Johnny fucking Capri in front of strangers at a club.
A few episodes later Capri ODs, He fucks someone in his house with the kid in the hospital, he meets other whores. Very much there could be a "Monster of the Week" with whores...But he always comes back to Capri.
Season 1 ends with the Facebook message to his wife. The message Pops up, the audience sees is. A womans hand picks up the phone....Cut to black.
CLIFFHANGER FOR SEASON 2!!!!
Ooooh, t hey could also overlay his texts with Capri while he is in scenes with his family.
Like during a nice family dinner his wife is telling a story about her day, and text bubbles just pop up with shit like:
"Then wolf is to clean your butthole, and I will inspect it"
