9 out of 10
The lips reaching for more
Deep sucking
Grinding on the O spot.
Tongue always out flicking and wrapping the skin.
Tongue running circles.
Tickle the balls with her fingers.
Stroking with her soft small hand.
To push this into a 10 would be swallowing and painting the cock with cum dripping down and sucking till limp.
Very good suck indeed.
Lucky man.
