Be Careful What You Wish For

My wife is older than I am, a retired social-worker with a masters in abnormal psych, and she is an actual control-freak, who needs to have her own way on EVERYTHING, and thus has NO problem with my obsession with being kept hooded at all times, and thus unable to disobey ANY whim she may command. Since early retirement after an inheritance, I have lost all touch with the real world, as our life together gradually becomes more one-sided, and I do what I'm told unquestioningly, to boost her quality of life, thus mine too...she crafts, sews, reads copiously, and watches some TV shows, which I am almost unable to hear, and certainly can't see. We cuddle on the love-seat, me naked, as always, and I tease her clit constantly, to her exact specification, while she keeps me locked in a stainless-steel 'cage' with only my balls exposed and vulnerable to abuse. She maintains that she can make me come through nothing but "testicle caress" but this remains to be proved...she isn't a great fan of conventional intercourse, preferring manual stimulation, and oral service, via the zippered opening at my mouth, in the heavy sensory-deprivation hood-helmet, she keeps me locked up in, most of the time.
We'd be happy to consider any suggestions anyone would like to proffer, for the enhancement of our weird sex-life....
