I find myself alone in a dark room. I'm naked and blindfolded, my vision black apart from a hint of red, flickering candlelight in my periphery. I'm bent over a table. My hands are tied to the opposite corners so that I'm forced to lie flat on my stomach with most of my weight on my chest, my heels lifting off the ground and only the balls of my feet touching down. I have some kind of clamp pinched to each nipple, crushed painfully against the table. My ankles are tied to separate table legs, keeping my knees locked straight which are also bound to the posts, splaying my thighs apart. My cock hangs down below the table in the open air, unprotected, pointing toward the floor. Something is tied around my balls, painfully tight, squeezing them and forcing my dick to remain hard and throbbing, bobbing up and down in space.
All the hair around my cock, perineum, and ass have been shaved completely smooth and I feel utterly exposed and sensitive, tickled by every fickle breeze. I feel strangely full and realize with a shock that I'm that there's a fluid in me--not my bladder, but my ass. Some kind of a syringe or baster has been inserted into my rectum several times over and used to fill it to the brim with oily lubricant; I can feel it dripping out every time I unclench, running down my soft taint, around my aching balls, down my shaft and finally onto the floor, making a drip-drip-drip sound in the silence. I try to move but I'm fully restrained--my toes brush against the floor without finding a foothold--and can only manage to make the table creak, my nipple-clamps twisting.
I hear a door open quietly and close again as you enter. Before I have time to ask what you're doing or shout for help, you've wordlessly yanked me back by the hair and shove a ball-gag in my mouth, fastening it firmly around my head so that I can't spit it out, a leather strap biting into my cheeks. I can only groan a muffled complaint as you run your nails down my back, over my dripping butt, raking my helpless thighs.
Suddenly something hits me hard, making a loud smack against the soft flesh of my ass. I yell through my gag. You tell me to shut up and begin to spank me viciously with a heavy wooden paddle, over and over, harder and faster, the room filled with echoing thunderclaps. My ass smarts as it jiggles under each new strike, fresh welts springing up. You tell me that this is what I get for misbehaving, that I'm a bad boy, a dirty man--that I should be your whore for once. You tell me that you're going to make me your bitch by the end of the night, that I'll worship the ground you walk on by the time you're through with me, that I'll never step out of line again. I try to disagree with you though my ball-gag. Between swings, you use an electric wand to shock my tenderized asscheeks, one after the other; then my sensitive thighs, then my swollen balls, making me twitch involuntarily each time. You electrocute my taint and I bite down on the gag, straining to get free, thinking about how I'm going to take my revenge on you, imagining what I'd do with you tied up instead. But despite my efforts, the bonds don't budge and I'm forced to take my punishment in full.
After what feels like an eternity, the paddling stops. My ass seethes in the open air, flushed with warm blood. You put plugs in my ears and now I'm totally cut off, both sight and sound taken away from me. The loss of these senses only makes the pain of my ass more noticeable. I have no way of knowing what you're going to do next, no way to prepare myself. My muscles stiffen in anticipation, but I have nowhere to go. The suspense makes every inch of my body tingle.
That's when you grab my cock from behind, bending it down and back between my legs, and shove a girthy sound inside of it. The well-oiled metal of the rod feels white-hot as it plunges the full length of my shaft and beyond, through my urethra and into my bladder, tickling my prostate. I struggle violently to no avail. You move the sound in and out roughly, fucking my cock with it. After a while you pull it out and I exhale in relief--only to yelp as you shove an even thicker rod in, stretching my urethra to its breaking point. You hold a vibrator to the tip and send shockwaves through my body, making me arch my back in a mixture of unbearable discomfort and shuddering ecstasy. You repeat this several times, expanding my cock wider with each successive sound until I lose count, and edging me with the vibrator until I can't think straight--a slave to the pain and pleasure you force upon me in turns.
When you finish I lie still, exhausted. My balls are engorged with unspent cum and aching, my asscheeks searing, my cock tender; my urethra has been reamed out to three times its normal size and feels raw from being fucked, dripping lube and precum onto the floor. I hope you've made your point, that you're done with me. You pull my earplugs out and I hear you walk slowly in front. You warn me not to make any noise and pull the gag out of my mouth. I pant, head down, trying to catch my breath.
