Relina's eyes went wide with fear when she saw the plug Frea pulled out.  Even with the lube, she didn't like the idea of having that thing inside her.  "I'll... I'll take the clamps, mistress," she said as she walked over to Frea's box.  She searched through, pulling out three clamps.  The ones she chose were some of Frea's weakest and lightest ones, clamps that would barely squeeze when they were placed on something.  Setting them down in front of Frea, she walked over to the cage and spread herself.  Her sex was still wet, perhaps even more than before, and there was soon a wet stain on the floor under her.
