The turd splashed upon his face...

[Marquis de Sade]

At Fournier's establishment we had another curious article of furniture:
a kind of toilet chair, provided with the usual hole and set against the
wall; things were so arranged that a man could lie in such a way that
while his body extended into the neighboring room, his shoulders passed
through an opening and his head occupied the place usually reserved for
the chamber pot. I had been appointed to the task, and kneeling between
his legs, I sucked his prick as best I could throughout the operation.
Well, this extraordinary ceremony consisted in having a workman, who was
paid to act a part whose full consequences he neither knew nor divined;
in having, I say, a man of the people enter the room containing the
chair, climb upon it, and do his business squarely upon the face of the
patient over whom I was toiling; but the shit bearer had absolutely to be
a poor drudge fetched in from the humblest milieu, he had as well to be
old and ugly, he was inspected before being put to work, and were he to
lack any of these qualities, our libertine would have nothing to do with
him. During all this, I saw nothing but heard rather a lot: the instant
of collision was also that of my man's discharge, his fuck sprang down my
throat the same moment the turd splashed upon his face, and when he
emerged from beneath the chair and got to his feet, I saw by the state he
was in that he had been handsomely served. By chance, after the exercise
was over, I happened to meet the fellow who had performed so brilliantly;
he was from the Auvergne, a good honest chap who earned his livelihood
working with stonemasons; he seemed delighted to earn a crown by doing
naught but ridding himself of what he would have had one way or another
to expel from his bowels, and this little chore struck him as infinitely
less arduous than carrying his hod. He was, what for his looks, quite
dreadful to behold and must have been over forty.

Il y avait chez la Fournier un autre meuble assez singulier: c'était une
espèce de chaise percée dans laquelle un homme pouvait se placer de telle
sorte que son corps dépassait dans une autre chambre et que sa tête seule
se trouvait à la place du pot. J'étais du côté de son corps et, à genoux
entre ses jambes, je lui suçais le vit de mon mieux pendant l'opération.
Or, cette singulière cérémonie consistait à ce qu'un homme du peuple, gagé
pour cela sans savoir ni approfondir ce qu'il faisait, entrât par le côté
où était le siège de la chaise, se posât dessous et y poussât sa selle
qui, par ce moyen, tombait à plomb sur le visage du patient que
j'expédiais. Mais il fallait que cet homme fût exactement un manant, et
pris dans tout ce que la crapule pouvait offrir de plus affreux; il
fallait de plus qu'il fût vieux et laid. On le lui faisait voir avant, et
sans toutes ces qualités il n'en voulait pas. Je ne vis rien, mais
j'entendis: l'instant du choc fut celui de la décharge de mon homme, son
foutre s'élança dans mon gosier à mesure que l'étron lui couvrait la
face, et je le vis sortir de là dans un état qui me fit voir qu'il avait
été bien servi. Le hasard, l'opération finie, me fit rencontrer ce
gentilhomme qui venait d'y servir: c'était un bon et honnête Auvergnat
servant de manoeuvre aux maçons, bien enchanté de rapporter un petit écu
d'une cérémonie qui, en ne faisant que le dégager du superflu de ses
entrailles, lui devenait infiniment plus douce et plus agréable que de
porter l'oiseau. Il était effroyable à force de laideur et paraissait
plus de quarante ans.
