She is currently 25 years old, she just looks younger because she's so petitie and her tits are so small (but cute).
If this is true (and could be, despite of her look), why the hell is she still playing the 18ish - or little more - all the time?
As for her enthusiasm, yes, I must agree. I have a 17min. video of her called "Tiny Lisa and a cowboy" where she shows her inner and outer sluttiness. Anyway, she definitely has some talent.
