Buried in the mists of childhood is something that brought me to an obsession with confinement in rubber bags, for ever-increasing lengths of time. It doesn't really matter which gender happens to be on the outside, in control, or age, or multiplicity even. I have done it all. I obtained some actual Vietnam-era bodybags from Army Surplus, made of a strong fabric, heavily rubberized on the inside, untearable, air-tight, water-tight. Olive green, black rubber on the inside. Strong full-length zipper. I got a "starving" seamstress, to alter it to a fairly snug fit for my body, and install a small zipper across the mouth, and at the crotch. She insisted on a personal 'fitting' which lasted for a three-day weekend, during which time she methodically made use of both zippers, for her own lengthy satisfaction, and milked me into a state of near-hysterical need, which amused this plain middle-aged rather dumpy woman, immensely. Admitting to having not been with a man for twenty years, she made up for lost time with a determined single-mindedness and much alcohol. I was powerless to resist, which seemed to be what I enjoyed as much as anything in life. Gradually recognizing this, she told me she would guarantee me at least ten orgasms a day, if I just stayed where I was, in her care and confinement. I won't bore you with the details, but she worked out a fool-proof way to keep me clean and fed and watered without ever getting totally free of the bag, which was ingenious and effective. When I asked her what would happen if I said no, she giggled tipsily, and said nothing would change, except for the ten orgasms, which would magically become none! So I agreed, and she told my landlord I wouldn't be back, and just to dispose of my thrift-store effects, and I became a resident in her tiny cottage. A year passed in a welter of sweat, slow suffocation, forced cunnilingus, and absolute r**e, and my enormous appetites were met! I no longer had any wish to be free, and admitted that while 'in extremis' in front of her two older sisters, who were happy to be witnesses to my voluntary enslavement. One of them worked in a blood and sperm bank, and let it slip that both 'motile' high-count sperm, AND the ooze they called 'pre-come' were much in demand, and would bring a premium in 'fees' for appropriate 'donations' under strict refrigeration 'protocols'. Suddenly my captress and her siblings were rather better off than they had been, and my orgasm count almost doubled! And the teasing became very lengthy, so they could capture the elusive 'pre-come' in sufficient quantities to satisfy the sisters' employers. his was before the days of Viagra, but the blood-bank sister knew of something illicit and highly effective, and I was dosed with it, liberally, producing endless hours of massive arousal, and huge quantities of sperm, enough for two 'regulation' conainers, usually. Ten years have passed, and they are allowing me to share this, anonymously of course....
