Okay, seriously NOT for amateurs.
Unless you are both absolutely sure that you can handle this position, please don’t try it as it could result in some accidental neck-breaking if you’re not careful. Basically, this requires the guy to have some super upper-body strength as he will be doing some lifting. If unsure of his bodily prowess, the lady can try lying on something, perhaps a counter-top, to achieve this position. Seems difficult, but I hear it can be extremely orgasmic. Have fun.
