This is called the knee-rock because of the action it makes the man perform. The woman lies on her back and brings her knees up to her chest, she can cross them if she likes. Almost like the fetal position but don’t think about that. The man then kneels in front of her and rests against the back of her thighs while he thrusts. With this position the woman receives full contact from the man and gets maximum sensation on her vulva, clitoris and thigh. This should not be used for too long as the woman will not be able to move too much and it is also quite an intense position. It also leads to quite deep penetration which some women will not enjoy.
