Upside Down Slide Sex Position is another new position which you can try if you feeling bored with the usual positions that you know. Watch out guy with flexible dick, this will put your shaft into test. Just how far you can bend it in the wrong direction? I am also thinking that good penetration can only be achieved if you have a long dick. Either way this position can be used for anal and vaginal sex! It’s her choice on which hole she wants you in. She in total control her, making all possible movement up and down, back and fort, and grinding. She has to support her weight by her legs, which can be tiring is she’s not used to squatting.
