A sexual escapade involving three men: a man lying face down on the bed who can be dead or alive, a black man wearing a Batman suit, and a man who sodomises the lying man. The man in the Batman suit defecates on the sodomiser's erect genetalia and stands in a superhero pose while the sodomiser sodomises the man lying down. The difference between the necrophiles and the coprophiles is mainly the absence of the corpse.
