Gay or bi-sexual Muslim males are scarce, but my fantasy would probably work for one willing to think outside the box, so to speak! I would love to be confined in near permanence in the most wickedly restricting burqa EVER - made of either leather or heavy latex, with a built-in lockable adjustable hobble-strap round the bottom, preventing it from being lifted above the knees without permission/cooperation. Small zipper at the crotch, another across the mouth, and a few tiny leather-punch holes at the nostrils and eyes, giving minimal air, and vision. lockable strap round the waist, pinioning my arms in a loose folded position, rendering me utterly at the mercy of my sadistic, demanding master, who could easily fool any "critics" into imagining the victim as female, which would make all this cruelty utterly acceptable to his peers. This arrangement would also allow him unrestricted use of my "goodies" via the zipper, or by lifting the burqa up and back over itself, secure at the waist, thus exposing my nether regions to whatever nastiness he might prefer at any given moment. I could be fed and hydrated through the upper zipper, and given use of the toilet, when I was suitably exposed as described above.
All it would take would be a truly dominant sadist, of enormous sexual energy and need, with privacy and the financial independence to make adequate use of his slave. Maybe he would have a few close friends who would discreetly share the secret...endless face fucking and the other variety, would be always on tap...I can imagine all sorts of variations on the theme, and hope I can meet the right person one of these days...
