Mistress's Boot Meets Sub's Ass

In a dimly lit dungeon, a stern mistress towers over a trembling sub, bound and kneeling on all fours like a dog. She circles him, her heels clicking on the stone floor, before landing a firm kick on his ass, sending him sprawling. The sub yelps, but the mistress is relentless, training him with her boot, teaching him obedience. She kicks him back into his cage, locking him in with a satisfied smirk.
