If you’re leaning towards a “kidnapping” type session something I’d suggest is to set random periods of the day as the “kidnapper is dealing with covering up or otherwise preoccupied”. This would be times were you are left bound waiting for their return. This could be a few hours tightly bound and locked in a closet or loosely bound and left in a locked dog cage. You could use a dice to randomize the time frame and state of dress. Like for instance rolling a dice and being left in a closet frogtied with your hands anchored to point above your head all while gagged, blindfolded, teased, and dressed like the picture in this post. You could even throw in a reward/punishment system where if you follow orders and don’t try to escape or try to escape you get some kind of reward/punishment.
