I read a review recently where it said unprompted, she got into the Viennese Oyster position for greek... I wasn't exactly sure what the VO position was so I googled it... OMG, erotic hot pics came up... It takes a lot of flexibility... I am wondering how rare this might be, many on here experience this position?

Yes, I have been with quite a few providers who have assumed this position.  It's pretty hot, but my favorite is still cowgirl.  Watching a providers tits bounce and having her grind her hips still does it for me the best.  However, everyone is different!

I agree, my favorite visual has always been the various cowgirl positions, perhaps reverse asian cowgirl the best of them, that is hot to watch, but just seeing the Viennese Oyster position eagerly awaiting my insertion, wow
