A Private Session Full of Surprises

I have always fantasised about going to a bdsm dungeon/club, find myself tied up and bent over in a private room with a dom, while he teases me with a bunch of toys, especially on my butt, and then surprise me with pouring melted candle wax all over me. I never tried it because I never felt comfortable with my own body, and I will probably never have the guts to do it, but I can't stop thinking about it.
