Blindfold on LetMeJizz
A scarf or strip of fabric goes over the eyes before anything else happens, and the whole scene builds on that one missing sense. With sight gone, every touch lands as a surprise, which is exactly what the setup is selling. Trust between the partners does most of the heavy lifting.
