There's quite a few.
The guy from the Swallow Challenge above is called 'Master Blaster', and there's at least a couple more with him :
Game Room Fun
Mystery Milking (on a milking table)
Other's with another guy :
Wifeys 1st Hotwife Load
Wifeys BBC Valentine
Dark Dreams
There's another I've seen posted under her alter ego name of Kate, calling itself Kate's Idle Hands, another milking table film.
