Liquid Nipple Torment

I recently watched a video on XVideos.com in which an attractive young lady was bound to an examination table for some torment of her scrumptious looking nipples. The torment seemed to center around spraying an unknown liquid on her nipples, which aroused her. Sorry, I can't find the video, now. 🤔

Any idea what the liquid might be? Is there a liquid that would, maybe burn a nipple for a short time and not leave marks or cause damage?

I don't know what it would be but rubbing alcohol used to do wonders for me when I was younger when I put it on my glans. At first it felt cold as it evaporated then it felt warm and tingled.

I like to play with nipples in many ways. With the help of tools, it would also be interesting to try small weak electrodes...

Even mellowed with a carrier oil, clove oil, and cinnamon oil stings on the skin. It might cause pain, discomfort, and irritation and some can cause an allergic reaction. Menthol, winter green, peppermint or other minty oils might also be uncomfortable. Using a carrier oil is always recommended recommended as essential oils can irritate on their own.
