No feedback on adultwork so looking for info on this woman.
Nice body indeed. Mind you, if she's 24 years old, then I'm the Pope! I think you're looking at a woman there who's at least mid-30s.
My guess is that she's probably Eastern European and genuine enough. The rates are also pretty decent and there are a few in the general area offering similar rates.
Depending on your budget, I'd probably try her out at the 30 minute rate to start with. If you then like her, by all means try the hour. I think it's best to see, first of all that she offers all the services advertised or if there's anything that costs extra. You'll get a good understanding of what's on offer if you try the shorter booking first.
