Is it something you do regularly during cunnilingus or analingus to prohibited from it ending until you decide?
I find it so sexy to be handled, trapped if you will, with the back of my head gripped, being held firm, servicing pussy and/or ass. Throw in if it's unplanned and instinctual with some really dirty talk until climax...oral doesn't get any better in my book!
So speak out ladies. Who grabs a guy's head without even realizing it and grinds until it's like "mmmm, that was good!...oops, were you not able to breathe?"
