Oh sweetie why are you acting up so much? I said you would get a reward at the end of the month and you behaved so good that I decided your reward would be a smaller better fitting cage. Now tell mommy that you are happy
It's been 4 months since you locked yourself up and lost the keys to your cage. At first you could resist not cuming, but by month two you got desperate, by month 4 however, you were a regular at the local love hotel and you were well known.
