"I think it's about time to get you back in your cage." Nikki had wound down on her conversation, and took a glance at your hard cock. "Oh, well look at that! Looks like we might need a little ice to help him out." So she quickly ran to the kitchen for some ice packs. As she pressed the cold bag into your crotch, she kept talking in your ear. "Just wait, next week will be GREAT!" Can you imagine how much fun it'll be with your cock in my mouth?" The effect was maddening. You wanted your cock to shrink down so she would take the ice away. But with her purring in your ear like that, it was taking much longer than expected!
When you finally shrank enough, Nikki put your cage back on. It was the new one, the gift from Mistress Liza, the one that was open so your cock could feel something besides just hard plastic, but also still very short so you couldn't get an erection in it. Nikki expertly put the pieces together with only the minimum required skin-to-skin contact with you. She threaded the padlock through it's hole, and slowly started to push it closed. Closer, closer. Then she leaned in very close to your face and looked you in the eyes.
