When I was eighteen, puny, bookish, and with raging hormones and no outlet, in desperation I went to the apartment next door, where there was a real brute of a man, who used to tease me in passing, crudely and offensively, sometimes offering to "wank me to death" and laughing like a drain when I got all red and embarrassed and hurried on by. Anyway, I knocked on his door one Friday evening, and asked "Can I come in?" when he answered. He stepped aside silently, grinning widely. He was fat, sweaty, bald, unshaven for days, in a dirty tee shirt and stained sweatpants, but I was in the grip of something stronger than me. "What?" was all he said, but he chewed his gum with a leer,picked his nose and wiped it on his pants, scratched his ass, and in general was utterly disgusting. Part of me wanted to flee, but another part just KNEW that if I was ever to find whatever it was I needed, this would be the guy! ANYTHING would go with him! I shrugged, and he said impatiently "What the fuck you want, kid?" I said "I dunno...have you ever tied anyone up before?" He chuckled and said "Better believe it, four-eyes! That what you want? I'll tie you up! Okay? You serious, or just wastin' my time? Ten seconds...! I drew a deep breath, faint apprehension trying to break through the fog of arousal. "Okay then, fuck off! " he growled and turned from me. "No, wait!" I said, my voice shaky. "Go ahead, do it! Quick, before I change my mind!" Suddenly serious, he went to a closet, telling me to get naked, which I did. I laid my glasses on a table, and suddenly things were all blurry, and he had the sleeping bag over my head before I realized what was happening. It fell all the way to the ground, and he was tying it at my neck, and waist. with rope or something. It stank! One end of the zipper ended right at my upper lip, and he slid it down an inch, giving me more air. "Okay, bub, you wanted to be tied up! What now?" he sn****red evilly. "I don't know.... whatever you say, I guess.....I mean it's not like I can stop you!" I said my voice shaky with fear, but with excitement too! Something was going to happen, I knew! "Good attitude, kid! You might even enjoy it! In fact I'll guarantee you enjoy SOME of it, and the rest, well I don't give a shit! I'm gonna enjoy it, that's fersure!" He slid open the other end of the zipper, up to my tightly-bound waist, pretty much, and took hold of my balls, with his fat fingers, squeezing and yanking them cruelly, until I yelped. "Shut the fuck up! In fact...." he slid the upper zipper tight closed, and now I only had what air I could draw through the metal zipper, and had none left over for the luxury of speech! He said he was going to "wank me to death" since his earlier offer had obviously drawn me here! That actually felt really good, especially with me utterly helpless to resist, but after a while, he pulled me close to him, slid the zipper back down, and pushed his tongue into my mouth! I wasn't ready for that, and the taste of tobacco turned my stomach! But I could do nothing but bite his tongue, and as helpless as I was, that didn't seem a good idea, so I just stood there and let him french-kiss me, endlessly, as he fondled me. He finally pushed a large pouch of chewing tobacco from his mouth to mine, then sealed me up again so I couldn't spit it out. The taste was awful! My hands, trapped above the rope at my waist, found areas of hard, crusty deposits on the cloth, and it dawned on me it was probably dried come! "Just to add to your fun, lemme tell you that old bag is thirty-odd years old, ain't never been laundered! I've sweated in it, peed in it, shit in it even, threw up in it, came in it, you name it! It's all in there, in some quantity or another! Gross you out? Huh? Good! When my six-pack is finished goin' through me, I'll piss it all over you! You only rent beer, y'know....! Sound like fun? Maybe you'll throw up in there, too!" His chubby fingers were driving me crazy, as he rambled on, and nothing else seemed to matter, not even his constant threats. He really seemed to enjoy telling me how he was going to keep me in the bag, all the time! "See how long it takes you to go fucking batshit crazy!" he gloated. I was so excited even this didn't really bother me, at that point, anyway. Then soon, he muttered "Gotta go!" and stuck his fat cock through the inch of open zipper, not into my mouth, but alongside it. Then he peed, and peed and peed, and the hot liquid soaked into the thick fabric, ever lower, until I was saturated right to the waist, at which point he withdrew and sealed the zipper shut again! Now the entire upper half of the bag was saturated with his foul-smelling piss! To be totally honest, I wasn't quite sure how I felt about that....it wasn't all bad, it seemed! Then the wanking resumed, tirelessly, and I slipped into am kind of dream state, as time passed ever so slowly. Just when I was about to explode, he stopped altogether, and re-zipped the lower half of the bag, then put me on my knees, and filled my mouth with his hot hard cock, ordering me to "suck it or die!" So I sucked it, with increasing skill, under his guidance, realizing it wasn't as bad as I first thought. It actually felt pretty good to my surprise. Now he rambled on about what all he was going to do, in horrifying but strangely exciting detail. The entire weekend passed this way, and I had never dreamed of such total sexual fulfillment. When it was finally time to get ready for work on Monday morning, I assured him that I would be back in the evening, and every evening, and every weekend, for EVER!
