For the record, she also has a fine ass, and she's a fitness freak too so very slim - would be hard to give her face/body/tits anything less than a 9 out of 10.
Thing is, as I've said, extras are non-existent, her demeanor sullen and bored, and massages passionless and completely lacking in technique. Hj also very forgettable too unfortunately
