The fact that the beauty product in question is from Japan is totally unsurprising.
Here's a VERY intriguing Japanese product from Ana Kasparian's "The Point." You have to watch the video to see what it's about, all I have to say is, any beauty product that involved wearing what appears to be a large ballgag and making blowjob motions with your head is A-OK in my book, whether it works or not! Having sexy news babes Ana Kasparian and Gina Grad discussion it does not hurt at all ... Ana's expression after airing the clip alone is worth the time it takes to watch the clip. "The Point with Ana Kasparian" has evolved into quite the fun little Youtube show.
By the way, Ana Kasaparian has a bondage porn clone. You can see for yourself here and here.
