Encounter in the wrong Purgatory

... As soon as the penitents opened that door, an auric glow blinded them for some seconds: presiding the hall, an immense, yellow and horned animal was seated on a throne surrounded by the pestilence.

And the pestilence didn't touch him, just floated around him, enamoured.
And the huge animal had a diadem of lightmilk on his astronomical head.
And he had white-varicose legs hanging from his mouth, like mostaccioli.

And his facial traits had almost imperceptible, but unequivocal human lineaments... and he spoke at last, and he spoke in Arab, and his voice was like the human voice passing through a Casio SK-60:

-"Ea, brethren of the good God, who is above, and is felicitous: we weren't waiting for your arrival in this tepid room, why are you here? ...But, but anyway I am glad we meet again after so long a-time, in this tepid room, after so long a-time [...] and you can open your eyes now: there isn't any Heaven or Purgatory, just Hell."

As the last phrase of the lifeless voice echoed on the isosceles walls all carpeted with rotting goats, the seated giant bit the pustules of his black lips, and swallowed the exuding pus with fruition: at his feet, undermined by the vice, small like vermin, grumous beings who once were human enjoyed orgasmic ardors in a bog full of yeast, looking at the unexpected newcomers with amazement.

The penitents realized that they were condemned to an unfair eternal punishment due to a bureaucratic error in the celestial calculus.
