After a long day of training slaves, Mistress Ayn likes nothing better than to sit back and relax as her slave lies beneath her and pays homage to her boots with his tongue. Mistress Ayn explains that these are no ordinary boots though, these have been chromed out with little bolts, gears, and spikes around the heels. He had better pay attention or he could slice his tongue on these dangerous boots. Ayn digs her heels into his nipples and taps her spiky boots against his cock cage to make sure he stays focused on properly cleaning her boots.
