Good question. I have no idea. According to the page's mumbo-jumbo, the STU is the most bestest feeling thing ever. And Supposedly there is an e-book with 'exercises'.
Yeah, that does look neat. The two problems I see are that it's like $90, and they say you only get like 50 uses out of it. Which really thats like $100 for a year's worth (if used once a week), so it's not too bad.
Burned through an Asa Akira "Forbidden Love" Fleshlight rather quickly last year. Tight and with lots of lube gave me some of the best nuts I've ever had, no kidding. Was looking into getting one of the Lupe Fuentes models but never got that far. Thing I hate about this is having to clean it afterward and then letting it dry. Always afraid I'll have guests over and spot it heh. Anyway, I recommend the product if you're bored and not getting any tang.
Wife just bought me a extra bottle of lube for my Tenga flip hole! No more filing up cavity with test tube like vials, now i just squirt it in like a bottle of ketchup on a dickhole sandwich
So it's like that realtouch thing, except in reverse. Guy bones pocket pussy, remote dildo thrusts in to chick based on his movements. Or I guess knowing the audience here it thrusts in to the asshole of a dude with tits taking hormones.
