Basic Right Angle Sex Position

In the basic right angle position, the partner being penetrated (portrayed here by our model B) lies flat on their back with one leg on the bed and the other raised in the air. The penetrating partner (who we'll call Model A) kneels between the thighs of their partner but straddles the leg that is lying flat on the bed. A then supports B's one leg that is up in the air (which is making a sort of right angle to the other leg, giving this position its name).
