There's a UK site called
www.CFNM.net that's worth checking out. Ocassionally the babes will strap-on some girly-dicks and bend the boys over for a seeing to.
There's a scene called
The Roast which is actually a pegging feature, with Alicia Rhodes, Donna Marie and a couple of other hot Brit babes. Basically, 5 honies take some lads to a hotel room and fuck them! See a preview here

Here's another scene called
Countess that, as you can see, features some sweet assfucking!

I see Donna Marie is in this one too! (Guess she likes fucking men up the ass?) But who's that super hot babe screwing the guy? Fuck she's hot!
