In the beginning she would try to assure me that my chastity was only ever meant to be a temporary thing. It had begun based on a recommendation from her sister after she learned about my 'performance issues' to help train me to focus on something other than my own selfish pleasure; any time I failed to fully satisfy her in bed my cock would find itself locked up for an increasingly long and frustrating sentence.
Just a few days at first, but quickly that became a week, then two weeks, three weeks, then a whole month, with minor reductions available for each hour I agreed to be tied down and edged or for every dozen orgasms I licked her to. By the end of that first year I was spending more time in chastity than out, having what I could only assume was the intended effect as my body began to crave her orgasms as it trembled with pent up lust, and my brain learned that it was so much happier when I didn't cum.
Meanwhile for her part she'd underestimated the intoxicating feeling keeping me denied for endless weeks and months, and found more and more that she dreaded those brief times I would be free of my cage. Her sister has earned this might happen and just encouraged her to embrace life as a goddess; I seemed perfectly content in my new place as her slave after all so where was the harm?
If I could've thought straight maybe I would have begged her not to when she announced her decision to make my denial permanent, but as sexually broken for her as I'd become I instead smiled, thanked her and asked to worship her pussy instead.
