Santiago: Leather
It was a large leather strap. Bigger than a belt. It hurt more, too. His father hit him across his legs with it, and eventually he rolled onto his stomach.
His father continued on with the beating. He was moved once more, and the leather rained down onto his back, and he could not help but cry out.
The beating went on for so long that Santiago could feel the pain blend. He could not feel each individual hit, but rather the collective, bloody, stinging pain.
Snot and tears ran down his face, and his father was far from finished.
