What is the Anniversary of Tap? Who knows and who cares? Is it about Spinal Tap? Probably not. Is it about the invention of the faucet? Doubtful. Is it about Tapping that Ass? More than likely not, but that's about the closest we've been able to come since the only thing we know for sure is that it's got some amazing boob and butt baring sex scenes from the gorgeous Mayu Kawana! Anniversary of Tap must be a salute to the first time you tapped one off to the magnificent Mayu!
