Definitely NOT 19. I would guess at late 20's early 30's - this is based upon her body and the way she interacted.
Pros:
Very good figure
Easy to deal with (despite language barrier)
Clean and well presented
Cons:
Photo's definitely touched up
Rushes - very brusque and clinical - no attention paid to creating a fun environment etc
Reeled of the usual nonsense and numerous fake orgasms etc - I find this very offputting and somewhat insulting, but it is what it is
