I have to say the early ones were more to my liking. I've never been close enough to a real lactating lady to know for sure, but the spraying out through the bra in a single stream seems a little odd. The very first picture was amazing, in particular.
I love the girl getting milked in the barn, that's silly but sexy too. Reminds me of the Chimerian Effect, one of my favorite stories. The girl who kept taking the BEcoli to make herself huge, ends up in her grandpa's dairy barn helping the family business.
