These key here signify that I control your freedom, I control your cock, and I decide whether or not to release you - to let you go. Guess what? I'm always going to decide not to. Oh don't worry, I'll keep the keys safe. Sometimes they'll be on a necklace, sometimes I'll just slip them in between My cleavage, and sometimes I'll hook them on the waistband of My panties. That way you'll never forget who controls your cock.
