A1 cock sucker in my book. Although she can't deep throat. She has excellent technique. One hand firmly squeeze his ball and base of his cock holding it in place. Using her other hand to stroke the entire cock and using her mouth on his head to make sure everything stays lubed up.
We even have difficulty deciding what to do with a wonderful dick like that! I don't know if I would be contemplating; I don't know if I would suck until my mouth was tired; I don't know if I would sit on him until I felt his balls touching my ass... To clear up all these doubts, the best thing would be to do all of this.
