Christmas is a time for...
Christmas is a time for giving, and I'm feeling very generous this year.
In my hand is the key that unlocks the chastity cage I put you in last Christmas. Since you've done so well locked up for a whole year, and been so obedient, and pleasured me in so many ways with nothing in return. Since you've been absolutely subservient to my will for a whole year, I've decided to give you the greatest gift of all. I'm throwing away your key.
