The Centaur Vet (named Rex) approaches your face and slaps you with the huge elephant cock he procured whilst exploring the jungles of Afrika. The stench is overpowering.
"You're a dead elephant's bitch", Rex proclaims with satisfaction.
The other Centaur (Axle), agrees and begins to prepare the Ancient Ceremony of Jurisprudence. The heady scent of incense curls through the room as he etches mysterious figures and symbols onto the dusty floor with a large stick of charcoal. Meanwhile Rex stirs the blood from your castration operation into a mixture of semen and melty chocolate.
"Don't forget the elephant dick" says Rex.
Axle gingerly places the gnarled grey cock, along with your recently removed testacles, into the blood/semen/chocolate mix and dumps the concoction into a huge blender with sharp metal blades. You wonder, "Will it blend?"
Axle sets the blender to 'frappe' and murmurs a Centaurian blessing as the mixture tornados into the frothy, sacred elixir required. The Centaurs moan in expectant longing. You look bewildered and slightly nauseated.
Rex pours the smelly brew into three studded goblets. You drink, somewhat reluctantly, but soon realize genitalia and bodily fluids don't taste so bad. The two centaurs are already throwing back their second. You notice Centaurian love poles elongating between hind legs.
"Nice party", Axle says, "but now it's time to fuck."
