What kind of things do you do to your partner when they are deprived of senses?

(Im 36m and fiance is 31ftm)

Fiance likes to be restrained amongst other victim type things. I like to deprive them of senses (headphones, blindfold, ballgag) but feel I fall into the same things I do everytime I do and was wondering if anybody else does this with their sub and what kind of things they do to make it more fun for their sub?
