The first variation is for the woman to arch her back & raise her hips in what is known as the Widely Open Position. This sex position requires the woman to raise her hips to meet the man. She can help keep herself in this position by digging her heals into the bed. She can also "push" into him with her groin to add to the sensations. With practice the woman can become a vital part of the rhythm during intercourse. This position also ads some friction to the woman’s clitoris & can help promote orgasm during intercourse.
Hard to do for long but when you just have to get off this works for me
Good for those wild sessions where she just has to get off.
