The most amazing sexual position ever! One couldn't even compare it to 69 or even the lazy dog!! It's simple enough, just get your unconscious victim... er willing partner to lie on the their stomach and place your "candy" on top of their "jiggle mountain". Relax and enjoy

Aaron: I have some from Mike too... at least it was fun

Caren: That's for true : way better than 69ing

Aaron: Or even the lazy dog!
