Mestre's grip tightens around the sub's bound wrists, his other hand delivering sharp, stinging smacks to the sub's already reddened ass. The sub, a willing captive, grunts and groans, his hard cock throbbing against the leather restraints. Mestre growls, "Take it, slut," as he increases the intensity, his hand a blur of motion, leaving the sub's ass a mass of welts and bruises. The sub screams, his cock pulsing, as Mestre brings him to the edge of pain and pleasure.
