My older brother was a sex addict at sixteen, and being overweight, bespectacled, and acne-ridden, was not able to deal with his addiction - other than through me! Somewhere he got hold of some REALLY kinky porn magazines, and stories, so consequently, me being a hundred pounds lighter, scrawny in fact, and not very brave at the age of fourteen, I was "roped" into his fantasies, as an unwilling participant. Our father went on business trips regularly, and Randy had bullshitted him into believing he was trustworthy, sensible and reliable, thus capable of being left "in charge".... So, I was subjected to all kinds of imaginative bondage and torture, always involving long sessions of having his cock in my mouth, for hours on end. He was insatiable, and after much complaining on my part about cramps and cut-off circulation, he fabricated a very effective strait-jacket, out of an old raincoat, rubber-lined, and with a draw-cord hood attached. He riveted a broad belt cut in half, to the sleeve-ends, and was thus able to buckle them effectively behind my back, loosely but inescapably. End of "problem" in his view, so the length of my confinement doubled and tripled, until I spent almost every minute of our unsupervised "togetherness" trussed up comfortably like that. The hood tightened down like a second skin, round my head and face, leaving only a wadded-up orifice over my mouth, just big enough to accommodate his tireless cock. We slept like that, even, while he face-fucked me every few hours.
Problem was, I was beginning to get very horny myself, by then, and looked forward hungrily to his clumsy assault, through the rubberized material, on my larger-than-average erection! When it dawned on him that my efforts to please him were directly related to the state of my arousal, things settled into an unwilling mutual effort. The inevitable happened - I quickly became as addicted to my helpless cooperation, as he did, from the opposite end of the scale, and his power over me was complete! Then Dad remarried, and his new bride, a plump foul-tempered 'bossy-bitch' caught us in flagrante, and blackmailed us into utter compliance, showing him the "carrot" and me the "stick"......She kept our father occupied all the time he was home, and enjoyed "supervising" our activities, whenever possible, with suggestions for him to escalate his torture and confinement of me! This went on literally for years, until Randy got his first job and left home! I was devastated, until Helga made it clear that it would be business as usual, but under new management! So, the orifice in the hood was plugged with a ball-gag. and she deftly inserted a six-inch zipper right over my crotch, giving her unfettered access to my tireless, eager cock! This was a new and delightful experience, but a few skillful punishments, through scary rationing of my air, taught me to take her needs and wishes very seriously, and concentrate on not coming, until she was completely satisfied, and brought me to climax quickly and mercilessly.
This lasted a long time, and I ended up marrying her daughter, another plump foul-tempered Germanic blonde, who was delighted to maintain the status quo, and looks like it will be permanent! Every submissive masochist's dream, I guess, but there is a down side - you don't get to see much of life, other than earning money for your wife, and then - the blackness of heavy rubber, and more sex than anyone but an addict would be comfortable with....
