I've got that clip It's a Bound2bMessy one from about 2011 called "Girls Pieing Girls", with Sarah and the (still wonderful) Fi Stevens
However, I can't see that it's currently available anywhere. It's not on either the main B2B site, or their "Video Vault" Vidown offshoot, which as far as I can tell actually has the same clips as the site itself. And, as the link to their Fi scenes on here shows below, it's not on UMD either I'm afraid
For what it's worth, I don't think they ever had a member's area in the sense another poster suggests. I was an avid collector of Fi's scenes back when she was active (she retired around 2012/13), and from memory B2B used to rotate clips in and out of their back catalogue over time as it took me a while to pick up all the Fi scenes I knew they had. So, rather than this one being stuck behind a paywall somewhere, it's more that it just wasn't on their active list when the Kowalski brothers (I assume) quietly retired, and now the selection of films is frozen at the point they last updated the site. I recognise a lot of the clips btw, and everything is at least ten years old! In fact a couple of Fi's go back to the mid/late-2000s...
But as I said, the clip the picture's from seems to have gone the way all WAM eventually does. Sorry.
Thank you everyone for the help. I know I had found it uploaded to a site at some point, but I couldn't seem to find it again. It's a shame when any video goes missing from the internet, but I guess this is just another.
