Just The Tip
You saw a pair of blue silk panties spread out on the bed, and your key on top of them! When you looked back, Nikki had pulled her boobs out of the dress and lifted the skirt to confirm that she was naked under that flimsy blue dress. "Why don't you take everything off - including your cage - and come over here so we can play?"
You quickly stripped as commanded. Then you took the key from Nikki's little silk panties and unlocked yourself. You cock practically threw the cage off it, as it sprang to full erection as soon as it was free. You looked back at the bed, then at Nikki, then back to the bed. You reached down and grabbed the panties, turned to face her, and pressed them hard under your nose and took a huge sniff. She smiled as you tossed the panties onto the bed and crossed the room toward her.
