To cut a long story short, I am being blackmailed by my next-door neighbor, who installed a small camera in the flimsy wall between his apartment and mine, and has recorded all my inventive self-bondage techniques desperation has driven me to! I'm a youthful 35, fit and healthy, with an appetite for hand-jobs verging on addiction! I'm also into pretty kinky stuff, with latex, and total enclosure/sensory deprivation, which involves a pretty complex safety regimen. Anyway, this guy, a retired corrections officer, in his sixties, borrowed the landlord's pass-key and copied it, and can let himself into my apartment any time, apparently, to make videos of me struggling in my weird stuff. I enjoy getting into a really slim-fitting 'mummy' sleeping bag, and tying the draw-cords tight enough that the built-in hood scrunches down tight on my head, leaving me only an opening about an inch wide, over my mouth. Then I masturbate lengthily, on and off, all night! Anyway, one Friday evening, with no date again, I settled down to this consoling activity, and didn't know he was there, watching, until I went to release myself, and couldn't untie the draw-cords! I struggled a bit, then rested, and that was when he revealed himself, by straddling me, and kneeling until his dick thrust into my mouth, and stayed there endlessly, as he threatened all kinds of nastiness if I didn't cooperate....as straight hetero as I am, I was utterly revolted, but unable to do anything about it, except maybe bite it, which didn't seem like a good idea, as helpless as I was! Gagged with his rock-hard erection, I cooperated reluctantly, and hours passed. I swallowed a lot of come that night, and managed not to throw up, and I was humiliated to find myself erect and desperate for some stimulation, but unable to reach myself, with the strap or belt or whatever he had secured round my waist. Finally, he withdrew, and got off me, and I gasped myself into stability, with enough air to speak, and protested vigorously. "Why are you doing this?" i whined, and he chuckled and said "because I can! Because I want to! Because you can't stop me! You get my drift?" I croaked "You can't just KEEP me like this!" and he said "Oh really? Why not? What's to stop me?"I didn't know what to say, and he sighed and said patiently "I OWN your perverted little ass, young man! I can make you a You-tube star, complete with address, S/S number, the works! Shit, I could rent you out to any serious face-fucker or blow-job hound, for good cash money! You're between jobs, you're an orphan, and there's NOBODY cares whether you live or die, or just disappear! You dig?" Now I realized the seriousness of my situation. He snipped a small hole in the bag, and my eight-inch erection burst out into the open. "Mmmmm! Very nice!" he chuckled. and began to masturbate me, slowly, intensely, ceaselessly, until I was gasping and groaning, desperate to come, but being carefully denied, just at the exact second I was about to explode! "Want me to stop?" He hesitated his fingering, and I groaned "Yes! NO! I don't KNOW!" which made him laugh. "You LOVE it and you know it! You want it to go on forever! Don't you?" I moaned indistinctly and he released me and said "Say it!" "Yes!" "Yes. what?" "I want it to go on for ever!" What was I saying! I hated this! But my body was making a liar of me, and we both knew it. "Just imagine, hour after endless hour of this, and all you have to do is suck cock! Mine, someone else's, what's it matter? Sounds pretty good now, doesn't it?" "Fuck it! Yessss!!!" I wailed, humiliated by the admission, but deep down knowing I had never ever experienced anything like this before, and determined to get as much of it as humanly possible, no matter the cost!
