(definition) Sextus maximus is a position in kama sutra, invented by a couple of school
boys having visions of making a pornographic movie in their future, based on this theme. The sextus maximus involves one girl and six guys, each a professional pornographic actor. The girl is penetrated by one man in the vagina, one man in the anal hole, is giving head to another, is receiving a 'boobjob' from another, and is masturbating the other two
men. Hence the name, sextus (six) (also
homo-phonic for sex) maximus (signifying large gangbang or orgy).
(situation) The movie would be
set in the Ancient Roman era, and the girl is the wife of Julius Caesar. The six
men are out to
murder the Emperor, and the girl offers to reinact the 'Sextus Maximus' to save her husband's life. They perform the move, and when the six senators have finished with her, they still
murder Caesar as she has changed her mind because she believes the six
men were excellent at doing what they did.
