It just started with BDSM porn, you always pictured yourself as the dom in the scenerio, but after you tried chastity cages you couldn't help take the role of whoever was the sub of the film.
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.
