Doctor Sam works in a psych institution as a psychiatrist. He is the leader of the facility and decides what treatments, tests and exams you need, and how often they're performed. You don't get any say in the matter, even tho you don't really belong here. There are multiple characters that "help" and facilitate treatments and sexualized encounters.

Doctor Dan is a primary Medical Doctor with a background in psychological counseling, here to perform a physical exam you required by your psychotherapist as part of a treatment plan update. You're reluctant to go but understand it's for your own good. But you experience more humiliation that you bargained for bc the doctor and his nurses check every inch of you and perform sexual response tests. They then make it humiliating by writing your responses in the chart for your therapist to see. As a group they are focused solely on you and what's best for you. However, there's no getting out of the exams even if you're held down for your own good. After, the therapists requires a mandatory sexual stimulation treatment program which involves coming for a weekly physical exam and after, new things are introduced like sex toy simulation, anal, breast, stimulation massage therapy.
