My ex's favorite first go to position almost every time. Reverse Cowgirl, sometime's favoring one side, tightening herself around me, every so often pressing her pelvis down with force so she can feel me bounce against her cervix. A flexible well postured woman, has the talent for rotating their hips, twerking their torso's in any which way she pleases. She would regularly remark on the sensation my penis was like a freshly cut key, or clicking puzzle piece, that it fit her pussy in the most perfect way, shape and form.
