So I've had enough visits to different pros both who work on the site and off site to notice all sessions are ended differently.
I've had good experiences to where time is up and while my cuddle time is over im given a final embrace. I change into my street clothes, given a bottle of water and a final hug on at the door. I don't feel kicked out but I don't linger either.
All the way to watching a movie during a two hour session and there being 8 minutes left on the movie and im booted out instantly as the timer rings. To everything in between.
