I was with a provider today and when she gave me a BJ she had something in her mouth that was so hot and my cock felt like it was on fire.  It did feel great.  Whatever it was she had to lean over the bed and replace it with another.  Does anyone know what she did?

alternate with cold.....    

LMAO

OOOOHHHH so that's who she was .... LMAO

which I've seen a few porn videos of, but never could grok that.

Never had that experience, and don't know exactly what she could have in her mouth that would comfortably allow for it, but nice to know of it and wouldn't mind trying it some time.

I have, however, had the pleasure of a blow job with the gal having something cold in her mouth like an ice cube, and once even ice cream.

The juxtaposition of the cold and the warm tongue is quite the turn on.

Oh, and if she is Satan after all:  You lucky SOB!

Did I just see a Heinlein vocabulary word?  

You know you're dating yourself, but I also know you don't care.  Grok on

You've figured it out.  

Just hot and good.

You could be right.

through the tip of my cock.  It wasn't half bad.
