It's cold. Dark, I can't see anything. Blindfolded. I think I'm naked. I can't move. Metal on my wrists, my ankles, my neck; total restraint. I'm on my knees bent forward and I can feel the cold concrete floor against my knees and feet. I hear dripping and it smells strange. Smells clean but odd, moist, sweaty. My arms are held forward and cuffed. I hear someone open a door and walk in. I try to speak and ask what the fuck is going on. My words are lost due to an open-ring style gag. My mouth is held open with a steel ring strapped in my mouth. My tongue licking and feeling, figuring out what the fuck is in my mouth. I'm making all kinds of pissed off gurgling sounds but the person doesn't respond. I hear the person moving things around, turning squeaking knobs. I hear a small hum like a motor turning on, and little puffs of air like a tire pump sound. I can't stop myself from drooling even though I've given up on trying to speak. All I can do is listen.
I hear footsteps approach. I feel a hand rest on the back of my neck. Finally they speak, it's Bryan.
"Relax William, I'll take good care of you. I've done this a few times and I'm getting really good at it. The blindfold keeps you from knowing any of our secrets, and the mouth gag keeps you from complaining too much. An unexpected bonus is that it makes your protests sounds like a cow in distress, which you are now."
Bryan's hand stroked along my bare back, soothing me with touch. His hand glided down my spine, reaching my ass. His hand gently followed the crack of my ass, brushing across my anus and reaching down further to wrap around and hold my balls. He carefully but strongly gripped my balls, pulling them slightly away from my body, feeling and weighing them.
"Oh yes, there's quite a few loads waiting for us in here. And I know how to get it all out, every drop, more than you could ever imagine. I'm going to place some temperature and heart rate monitors. These are both for your safety and to let me know your semen production potential."
I felt Bryan press two sticky sensor pads on my chest. Then I felt two more being placed onto my scrotum, one on each side of my balls.
" There we go. Your heart rate is pretty high, William. Try to relax, breathe slower, you can trust me." Bryan resumed rubbing my back a bit and I was able to relax a little, despite being freaked out still. "There we go, now you're relaxing. That's good. I need you to be relaxed for this next part. I'm going to insert a pretty large plug into your ass. I'll work you up to it with my fingers as best I can, but it'll still be uncomfortable for a bit until your rectum stretches and relaxes around it."
As my mind processed what he just said, I heard a glove snap on his hand and lube being squirted out. I jumped when I felt his gloved hand rub lube onto my asshole. But it felt good, he has a gentle touch. Then I felt the tip of a finger begin to apply pressure against my anus. I was still tense, but trying to relax.
"It's okay, just breathe and let me in." I took a deep breath and slowly let it out, relaxing as I breathed. I felt my anus relax and his finger push me open. He kept pushing in, his finger gliding all the way in until I felt his knuckles against my ass cheeks.
"There we go, good job. Now try to relax and breathe while I put in another." He gently pushed a second finger in, all the way to the knuckle again. Two fingers deep inside my ass. He just held them still, not moving. My ass kept clenching onto his finger. We sat there for what felt like an hour, not moving, just relaxing. It was probably only a couple minutes. When I was more relaxed and my ass had adjusted to his probing, he began slowly moving them in and out. This felt incredible and my cock began to grow uncontrollably. I heard him squirt more lube on his hand on work it inside. Suddenly and gently a third finger slid in. I was really getting stretched.
I felt Bryan reposition his angle a bit. Then he carefully curved his fingers down toward my prostate. When he found it I felt a flood of sexual electricity shoot through my groin. It felt incredible! He wrapped his three fingers around my prostate, rubbing, feeling, massaging. My cock was rock hard and I was moaning and drooling into my gag.
"Easy little cow, don't go making a mess before we're ready."
Bryan's fingers began slowly pulling out of my ass. I felt stretched and I could feel my ass gaping wide after he removed his fingers. I heard him pick up something metal.
"Now just relax and breathe. This plug is electric and has a warming feature so it won't be cold. It matches your body heat. Now just breathe."
I felt the tip of the metal plug touch my asshole and start to push in. It wasn't cold like I expected the metal to be. At first it wasn't too uncomfortable, but once the plug went beyond finger length, I realized it was getting bigger fast. Also it started to curve down as he inserted it, directly rubbing against my prostate. I couldn't believe the size. This felt more like a giant metal dildo than just a plug. I kept expecting it to be in all the way, but it just kept going further and getting bigger. I was moaning and drooling, my hands grabbed onto a pole and my body was sweating. Finally my asshole popped over the largest part and settled around a narrower spot, designed to keep it inserted, like a butt plug. It felt massive inside of my ass, and the heavy weight was putting pressure right on my prostate. My cock was twitching and painfully hard.
Then I felt some leather straps around my waist. I felt extra pressure on the plug as he fastened the straps into place, they lock the plug into my ass so I'm unable to push it out.
"Now just rest for a moment and get used to that. I know it hurts, but I know it feels good too, doesn't it, William?"
All I could do is whimper a little and drool. He was right. As my body accepted and relaxed around the massive steel intrusion, it really did feel good. I felt full, helpless, and owned. My cock was still aching hard and twitching. Every involuntary twitch of my cock made my ass squeeze around the metal plug, forcing it to rub against my prostate. If I tried pushing it out, the straps kept it from moving out too far, and pushed it back into place. Sometimes it felt like I was being fucked with it as my body tried unsuccessfully to push it out and it came right back in.
"Okay, now for the next device. This one isn't painful, you'll actually love it...at first."
I heard him pick up another device and move closer to me. He reached between my legs and wrapped his hand around my cock. I felt a warm washcloth cleaning my cock, then his hands applying a thick lubricant, something like vaseline. His hands felt so good massaging my cock, but they stopped just as it was getting good. Soon I felt something start slipping over the tip of my cock, a smooth rubber lined hole with a hard metal tubular frame. The device kept sliding further onto my shaft, the soft rubber inside feeling like a pussy or a mouth. As it reached the base of my cock, my tip slid into a ribbed and tighter sleeve at the furthest end of the tube. This end pocket fit around the ridge of my cock tip snugly, gripping it at the ridge. It felt like I was all the way down a throat. Then I felt more straps. Bryan was strapping this device onto my cock. I felt like cattle, helpless and used.
"Feels pretty good, doesn't it? Just you wait. You ready?"
"Nnnngggghhhh," was all I could say. I sounded like a cow in distress. I heard Bryan walk over toward the sound of the humming and air pressure. I heard him flick a switch, the humming picked up pace, and the hissing air pressure sound began puffing in rhythm. The device on my cock slowly began tightening, feeling like a blood pressure monitor as it filled with air. Once it was tight, I heard another switch get flipped. The device began slowly moving up and down on my shaft. Oh my god it felt amazing. It felt like a firm handjob and blowjob at the same time. It was still moving slowly, and the ribbed end was bumping up and down over the ridge on my tip. It felt so good. I was moaning and drooling like crazy.
"Very good. Feels nice doesn't it? You'll never have a blowjob as good as this machine can deliver! This first orgasm will be an easy one. Go ahead and let it out, I'm ready for it."
With that, he must have turned up the pump a little bit as it began moving up and down a little faster on my cock. Back and forth across the underside of the head of my dick. Closer, closer. Fuck, I couldn't take it much longer. My ass clenched down on the metal plug, pushing it against my prostate as I felt the first spurts of my semen start shooting out my cock.
"Good job, you're doing great. Give me your cum."
