"Mr. Caffeine" bombs as the emcee of Ubisoft's E3 press conference.
The principal focus of The Human Centipede II (Full Sequence) is the sexual arousal of the central character at both the idea and the spectacle of the total degradation, humiliation, mutilation, torture, and murder of his naked victims.
Examples of this include a scene early in the film in which he masturbates whilst he watches a DVD of the original Human Centipede film, with sandpaper wrapped around his penis,
and a sequence later in the film in which he becomes aroused at the sight of the members of the 'centipede' being forced to defecate into one another's mouths, culminating in sight of the man wrapping barbed wire around his penis and raping the woman at the rear of the 'centipede.' [source]
I like the idea of a man becoming obsessed with the first film, but don't understand why a sadist would impair his pleasure by wrapping sandpaper and barbed wire around his penis.
