My Step-father Maintains That "wanked To DEATH" Is A Real Thing

I'm unfortunate enough to be an actual claustrophile - obviously the opposite of "...phobe" - most dates find an excuse to leave real quick, when I spring this on them.

Then I met an actual grandmother, sixtyish, gray-haired, horn-rims, over which a pair of cold grey eyes studied me thoughtfully, who professed curiosity in this new(to her) preoccupation of mine, and a willingness to "try anything once" - dismissed casually as an understandable willingness to exploit a well-hung much younger male, whatever it took...

To cut to the chase, so to speak, I let her confine me in my expensive rubber bondage-bag, purchased online. Once she had be bound at the4 ne4ck and waist, my arms trapped in a folded position, she caressed me into straining erection protruding from a well-placed zippered opening, and got on top of me, easing me inside her tight sex, and settling down to a very lengthy session of pseudo-r**e, while pressing her mouth to my mouth, behind another air-tight zipper, occasionally moving her mouth to cover the two mental-ringed air-holes at my nostrils, introducing me to extreme 'breath-play" which just blew me away, despite her threat of dire consequences if I left her unsatisfied...I did my damndest to delay my orgasm, to a reasonable amount of effort and success, but this old nympho was insatiable, and I knew my fate included many repeat performances...

We've been together five years now, and I delight in being her helpless sex-slave and "boy-toy"
