Good review, Argento, and an accurate depiction of Gina whom I have seen multiple times. As you say, she has a lovely personality and gives a great service. Highly bright; PhD student, or something.
You must have a good technique if you got her to come; I've only ever managed to bring her off twice in many sessions.
I know it's subjective, but I find her figure a total turn on. Slim but curvy with large breasts which, in fact, are only a 'B' cup, for connoiseurs of that kind of thing! Anyway, she's one of my all time faves.
