Day 5 red and blue

Five days in and the final exam hits hard. Both sluts kneel naked and cuffed, tits out, waiting to see who keeps her collar. They open wide, throats stretched around thick cock, drool running down those big tits while a beard scratches their thighs. Every slurp is scored. One slips, earns a sharp smack across the ass. The other keeps steady, nose pressed to skin, taking it deeper. Hands stay behind their backs, restraints digging in, proving they can serve even when they can't move an inch. Their asses get spread and taken next, stretched slow then fucked hard, each thrust counted as another point. The blonde's heavy tits swing with every slap of hips. The one who breaks position or comes without permission racks up demerits fast. By the end, the numbers are tallied and one girl earns the right to climb higher. The other packs her cuffs and walks.
