I never saw anything to indicate those particular kinds of bad habits in the studio girls. Maybe some of the studio owners have a sideline in other kinds of contraband.
That seems too over the top. In my hobbling career, I have never once seen or heard from anyone there against their will. Most of these girls are there solely for the money, either because (Staff edit) shortcut at life. Most likely this was a side gig, but it will only help the cops nail the studio owners.
I've not once ever gotten any hints that any of the AMP/Studio girls I've been with had a habit and that is something I can pick up on in a heart beat.
Folks have posted some of the legal documents, but I only see Tokyo spa mentioned not Sunflower or Kfest mentioned in the complaints. Are there docs that actually mention Sunflower or Kfest?
