In a dimly lit, Mexican dungeon, Regiodickass, the reigning king of ass castigo, wields his iron rule. His victim, a delectable behind, arches and jiggles, eager for punishment. Regiodickass starts slow, the rule's sharp tip tracing the curve of the ass, then sudden, stinging blows, leaving perfect, red welts. The room echoes with the symphony of rule on flesh, interspersed with the recipient's gasps and moans, their body writhing in a dance of pleasure and pain.
