where can I find more sample pictures of this

I'm pretty sure that's Kym and London Andrews (Vicky) from "Pour it On." The video is available on wetandmessy.com

I think you have to join to download it, but there are some great videos on that site. I'd definitely recommend it.

I second that emulsion...joining wetandmessy.com is a decision you won't regret. They have a fantastic back catalogue of material and the membership fee is really affordable. Do it..you won't regret it.
Here are just a few compelling reasons to give them a few quid for some truly A1 content

That's the thing about samples... they tend to be finite because they are samples.

Go drop some coin if you like them... you also help the producer make more.
