Hey all, I found a link for this and haven't seen it posted on here before (I'm sure someone will try and prove me wrong!)...But...This film is so brilliant it deserves to be seen if anyone like me missed it first time around! The rather sexy porn star Kimberly Kane gets a rather brutal introduction to sploshing! Enjoy!
In addition to this excellent Documentary, there is also an entire "lesson" about WAM / Sploshing with Mistress Shae Flannigan (she's the one doing the instruction in the Munchies Documentary above) on Kink University.
