Not enough videos have the sub getting ready for it. They're always just already tied up. Which sucks because that brief moment where they're in some tight, revealing outfit that's all straps and locks and latex but are still free is the best bit. They're chatting or relaxing or acting out a scene like any other day, but you know that within half an hour they'll be in some horribly intense, complex bondage rig getting their brains fucked out. That combo of cute girl in non-sexual situation with really objectifying outfit just hits.
Also, sometimes they use it to set up the scene more. The Gord video really draws it out. The innocent, regular girl is stripped nude and forced to put on skintight fetishwear against her will. Then she's strapped into some fancy rig and trained, and all the while becomes ever more aware of her inevitable fate and the world she's entered. It's such a hot progression.
