You can get that toy from www.primalhardware.com
it's called the tonguetacle I believe. I'd link but copy and paste isn't working for me on mobile.
I had taken a look at getting one as a colon tube for myself, but in the end opted for a colon tube from siliconenozzles.com. I liked the idea of having a bore hole for enemas and lube shooting, so maybe just an idea to think about. I do live how sexy this toy looks though.
Also, Natalie Mars is a national treasure and an inspiration to all sissy anal stretchers.
