Harveytherabbit: Like my comment on the other animation from the different angle, the arm is the problem. I like the pressure on the groin, but the way the hand seems to magnetize to her mouth is not sensual. Something like slowing it down and arcing into her mouth from below would have added a lot. I'm not fond of the slap either, it feels like it's from the wrong direction and a bit too harsh a slap. I'm not fond of slapping in general, but when it's done well in a sexy way it's usually a short distance and more of a steady motion than a wind up and pow.
