This is the moment of the story, where the first POW is led on the auction block:
"In a corner of the tent the men erected a low platform, where two guerrillas drag the first POW, fully naked and with his arms tied behind his back. He's sinewy and sturdy young man, with face features a bit rough, like a farmer. Not very tall, but with big muscles, he resembles a bull, also for the heavy and very big nuts dangling between his legs. He's similar to the hairy and masculine para sergeant - with impressive manhood -which one of the gentlemen has just bought from the guerillas. But the penis and the gonads of this bull are even bigger and heavier."
