The serf's body is a canvas of red lines and sweat, each mark a testament to their master's artistry. They gasp as the master's whip cracks against their stomach, their cock hardening despite the pain. The master watches, satisfaction etched on their face, before stepping closer, their breath hot on the serf's ear. "You're mine," they growl, fingers digging into the serf's hips, leaving bruises that will remind them of this session for days to come. The serf nods, eager for more, for everything their master desires.
