Chemical play can indeed be edgy play - because once it's unleashed, there is often little you can do.

I do want to offer up a real world solution for one specific type of play. Here is the set up:

I was doing figging with a sub and he got used to the sensation rather quickly, so I decided to add some Capsaicin to the mix. It became much more than he could deal with very quickly and of course removing the Capsaicin laded ginger root did nothing to provide relief. From somewhere in the back of my mind I dredged up the idea of using olive oil as a remedy - and it worked!

Thankfully this was a FemDom Mansion event, so I had olive oil upstairs in the kitchen. If you engage in this type of play, you might want to keep some on hand.
