If you want to break the monotony of your sessions. I'd suggest you incorporate hot candle wax fetish for an upcharge.
Now this can be dangerous and requires skill but the pleasure mixed with pain is worth it.
Ladies start by lightly dripping hot wax on your clit...and then slowly on your labia folds. At this time you should now gently start ouching, ouueing, or moaning. Let your client give it a try too. Make sure he has a steady hand. Next throw your ass in the air...spread your cheeks and let him drip that hot wax straight onto your booty hole. I imagine if you do anal maybe your reaction is similar to a slight knee jerk and then ahh followed by a devilish grin.
Next see if your client is amenable to you dripping hot wax on his tip. The effects of all this is to excite the mind with quick tingly flashes of wax heat and then the body will be opened to new receptors.
Drip wax also on the feet, belly button, ear lobes, or any spot on your body that's typically your erogenous zone.
I'm sure this will be a new experience for many of you.
Good Friday and Happy SexWaxing ;-)
