Phantom Cock Syndrome

The term used to describe the sensation of discomfort momentarily after the event of anal intercourse. Said receiver may feel the presence of a male member still engaged in penetration, when infact he is no longer attached to the anal sleeve and the gape is returning to its original starfish-like form.
