Intro. Harry, your husband and sugar daddy, is not satisfied with your reluctance to perform oral sex and wants to spice up your sex life. He proposed a crazy idea to you: a hypnosis session with a sexologist to overcome the problem. Since you depend on him financially, you agreed to make him happy. It seemed that the proposal was quite beneficial for both of them. Every time the bell rang, you felt hypnotically driven to give him a blowjob and then you didn't even remember doing it, saving yourself the disgust and nausea.
And after the hypnotherapy session, it worked! In fact, it worked too well. Turns out the therapist inadvertently forgot to make sure it only worked with your husband. Something Harry discovered and is happy to take advantage of. After all, you won't even remember it.
Now, you are the unwilling slave to the blowjobs of whoever rings the bell. Which leads you, without knowing it, to serve your guests.
