it is called the 9th level of an orgasm
Level One (lungs): the woman sighs, breathes heavily, and salivates.
Level Two (heart): while kissing the man, she extends her tongue out to him.
Level Three (spleen, pancreas, and stomach): as her muscles become activated, she grasps him tightly.
Level Four (kidneys and bladder): she experiences a series of vaginal spasms at this time and secretions begin to flow.
Level Five (bones): her joints loosen and she begins to bite her partner.
Level Six (liver and nerves): she undulates like a snake, trying to wrap her arms and legs around him.
Level Seven (blood): her blood is "boiling" and she is frantically trying to touch her man everywhere.
Level Eight (muscles): her muscles totally relax. She bites even more and grabs his nipples.
Level Nine (entire body): she collapses in a "little death," surrenders to the man and is completely "opened up."
