This position is rather complicated, so to listen to your own feelings and do not risk, if you are not sure in your abilities. The woman lies on the couch, leaning her back against the armrest and presses her straight legs to the body. Her arms are under the head. The man puts his feet on the armrest, crouches and grabs the armrest with the hands, placing between his straight legs. The male partner enters the woman from above, swaying on his legs and moving his buttocks.
