The serf, collared and shackled, kneels before their master, head bowed, eyes downcast. The master, dressed in black, circles them like a predator, their voice a low rumble, "You exist for my pleasure, my pet." The serf nods, their body trembling with anticipation. The master grasps their chin, tilting their head up, "Look at me." Their eyes meet, and the master smirks, "Good. Now, let's begin." They grab a riding crop, running it along the serf's cheek, down their neck, tracing their collarbone, before snapping it against their nipple. The serf yelps, their body jerking, but they remain in position, ready for more.
