On top of Irving's impeccable customer service, this video (his fourth) shows continued improvement over his nice first efforts.
Powla seems considerably more ticklish (a 7 on a scale of 10) than the models in his first two videos, and Irving does all the tickling himself in this one. This is a good thing, as he obviously knows even more about what he's doing, and he tickles Powla pretty aggressively (6 out of 10) at times, although never torturously. "She's a "friend" of his, which is probably what holds him back from being more intense.
The restraint was good (8 out of 10). Although in the opening scene she was able to lower her arms when needed, this was corrected promptly, and he was able to tickle her all over, at will, the rest of the way.
Powla's the most attractive model (a 7) he's used to date, although at many points in the movie she was wearing a black mask over her eyes (a blindfold or a disguise? I could never tell).
I've already exhaulted his customer service (12 out of 10!) in another post under the "Discussion" thread dated 10/8. Suffice it to say, as he learns and improves, this'll be a site I keep my eyes on.
