Mystery roleplay night

One partner plans a whole scenario in secret, and the other only finds out once it starts. For example, you tell them “Next Friday, be home at 8, don’t ask questions.” Then you set up a scene – maybe you transform the bedroom into a “spa” or a “strip club” or a “doctor’s exam room” and you have a roleplay ready. The surprise factor and the effort you put in can be very arousing. Give the other a veto token they can use at any point if they are uncomfortable or want to stop the scenario (so they feel safe despite not knowing the plan).
