When couples come to an idea of trying anal sex out, they, usually, do that in a doggy style but this couple is too nasty to do it that way and that is why they decided to perform it in different positions and to shoot a video in order to choose the best position.
It was her first anal action and the cutie was so nervous that her anus was totally dry and very narrow. The dude had to use his fingers and tongue to make her relax and to prepare her for the moment of penetration.
At first they tried a variation of a missionary position out but then the chick rode his dick.
