Bukkake Anal Anatomy
Two closely spaced muscle rings, called sphincters surround the bukkake anal opening. The outer sphincter
is controlled like any muscle, you can contract or relax it at will. The inner sphincter is goverened
involuntarily and it responds to fear and anxiety, causing the receiving partner to tense up the
inner sphincter. You can learn to control the inner sphincter by inserting a finger into the anus while
in the shower and concentrating on the muscle group.
Richly endowed with nerve endings, the anus is also interconnected with the pelvic muscles and is
known to contract rhythmically during orgasm.
