Ideas for the less used senses?

[Quarz]

Basically a random thought of mine.
Looking through cards the majority of them is aimed at the sense of touch, be it now stroking, slapping or something else. And most of the rest are not aimed at senses at all.
Hearing and sight mostly are stimulated through porn, but aside from that don't find much use.
Even less use find taste and smell, even though from what one reads many people think they are very important for sex.

So I am curious, which creative things one could do during teases with the (at least after my observations) less used senses. (not that they are unused, smelling underwear is well known for example)
Any good ideas?

Could do like a mind control. For the next week, find one scented candle and smell it every time you cum. After a while that smell would end up turning you on when you smell it randomly.

Or something like that.
