It was the day after my 21st birthday, I was finally old enough to drink! It was early in the evening, so I decided to walk down a few blocks to a neighborhood bar. It was pretty quiet inside as I sat and ordered a beer. An older man was sitting just down from me, and I noticed he was eyeing me. He wasn't in bad shape, probably in his late 40's with a goatee, brown eyes and a sturdy figure. After a few minutes, he came down started talking to me. He was friendly enough I found him quite interesting. At some point we were discussing hobbies and he mentioned robots- specifically how he liked to make them. He was an engineer and seemed to specialize in all kinds of advanced machines.
By now I had had 4 beers (he insisted on buying the last 2) and was feeling kind of drunk. Suddenly, he asked if I would like to come over to his house and see some of his work. Normally I would have been more cautious but the alcohol has loosened my inhibitions. I agreed to go, stopping only to pee before we left.
His home was a relatively short walk from the bar, and it seemed quite big. He led me into his workshop at the back of the house before handing me another beer. I began to examine some of his handiwork and was quite impressed! He hadn't been bragging about his skills.
Out of the blue, he asked me about my sex life. That sort of jolted me and I slowly answered "Sure, but..."
He laughed. "I'm not asking you if you wanted to have sex with me, I'm a lot older than you are."
I felt relieved. Truth be told, I had never been approached about sex (neither had I had much experience), so I didn't know what to say.
He then astonished me by asking "Would you like to go for a ride on a machine?"
"Ride? What kind of machine?"
"A sex machine."
I couldn't believe it. I knew about vibrators and small toys, but an actual machine?
"Come, I'll show you," he said. My curiosity, mingled with my slight arousal at the mention of sex, got the better of me. I followed him into a smaller room at the back that I hadn't noticed before. It was very dimly lit, with light background music playing. In the center of the room was what resembled a large massage table with a small bed on it.
He said, "Take off your clothes and put them on the chair over there."
I hesitated. Sure, I'd had a good time with this man so far, but could I trust him?
"I don't know about this..."
"Nonsense, you'll enjoy this and it will feel real good. It'll be like nothing you've tried before." I knew I had had too much to drink as I found my self-undressing. I walked back to the table and he demanded, "The underwear too!"
"But I-"
"Don't be shy, it's just us." So I slid my underwear off and found myself completely naked. I felt embarrassed standing in front of him, but luckily the lights were dim. Nobody else had seen me naked except the family doctor and the high school football team when we took our showers. I was wondering what he would say if he saw my hard cock, since it was over 7 inches long. Although I was nervous, I was also getting aroused.
He told me to get up onto the bed and lie with my head on the pillow. I don't know why I felt compelled to do what he said, but I obeyed. The bed was designed so that my upper body lay comfortably on it while the lower part sort of dangled off. I assumed he would remedy that. The part I was resting on was soft and comfortable, making me feel drowsy and comfortable. My cock grew harder.
Then told me to spread my arms and legs out a bit more so that I was at a spread-eagle. I did so, unassuming, as he came near the head of the table. I didn't know what he was doing until he pulled out some soft, padded Velcro cuffs that I hadn't seen before. They were attached to the bed and before I knew it, both my wrists were bound securely.
"Hey!" I half-heartedly protested.
He shushed me, telling me it was just part of the machine. I didn't want to admit it, but this twist was beginning to turn me on even more.
He came down to where my legs were and pulled out two padded leg rests for my lower body. Putting my legs on each, he secured me to them with two more of the same Velcro cuffs around my ankles. Now I was completely helpless and starting to feel scared.
He reached under the table to adjust some knobs and the next thing I knew, my legs were raised up in the air, bound and spread. I got even more scared.
"You're not going to..."
"What? Fuck you? No, I won't be doing the fucking." He chuckled and went to behind my head where I heard him fiddling with some equipment.
I was completely under his control, trapped and unable to move.
He flipped a switch on the wall and a small spot light came on, shinning down from the ceiling on my cock, balls and my ass. Oh God! It was like almost like a small stage light which illuminated my privates and my ass!
Then he reached down between my spread legs and brought some kind of mechanical arm up from under the table. I tried to raise my head to see what he was doing. The arm looked like it had been modeled after a human elbow joint, able to go back and forth in a thrusting motion. Attached to its end was a medium-size, thick dildo. He spent some time adjusting it and coating it with what I assumed was lube, until I could feel him pushing right against my asshole. I started to make a noise to object, when he suddenly came up to the head of the table and popped a rubber ball gag in my mouth! He lifted by head as he tied it and then let it drop back on the pillow.
Damn! What was I to do? I could only make small groans now, no matter what I tried. He leered at me and said he'd remove the gag after I'd tried the machine for a while. I needn't have worried about having my asshole torn though. He turned the machine on and the dildo began to tap slowly against me. It didn't actually go inside, but just kept bumping against the entrance, like it wanted in. I had never thought of my ass as an erotic spot, but this was making me reconsider. He adjusted the speed, making it go a bit faster. Tap. Tap. Tap. Oh, it made my ass feel funny.
The man approached the side of the table and reached up toward the ceiling, bringing down another mechanical arm. This one he positioned near my cock. It had a sort of cylinder, unlike the one with the dildo. He opened the cylinder and I could see it had some kind of foam lining inside it. He put some kind of massage oil all over my cock. It was soft because I was still kind of scared. Next he placed the cylinder around my cock and closed it so my cock was trapped inside. I noticed the cylinder was open at both ends. He made some more adjustments to it.
Then he took a small leather pouch and forced my balls inside of the pouch. He then tightened the strings on the pouch so my balls could not escape. A small string from the bottom of the pouch was attached to the arm. He made a final adjustment to the arm from the ceiling and turned it on. It pushed down to the bottom until it was touching my crotch, then it slowly went up until my cock head disappeared inside. Then it started down again.
Every time the arm pulled up, the pouch with my balls inside went up as well, pulling my balls with it. It was not painful but very erotic. He'd tied them in the spot that could get maximum stimulation. Ohhhhhhh. Then it went back down. Ahhhhhhh.
He adjusted the speed until it was going faster and faster. My cock swelled and grew as hard as it could get. It was so tight inside the cylinder, in fact it felt like it was tightening and releasing each time my cock was inside. I was moaning uncontrollably now. With each stroke my cock head would disappear inside the cylinder and then on the down stroke my cock head would fully appear outside again. My cock head is especially sensitive and this kind of stimulation was driving me crazy as it kept me just on the edge. It was feeling so good; I had never felt anything like this while masturbating.
He slowed the cock machine considerably and then went between my legs, adjusted the dildo so it was entering my asshole just a little. I felt myself squirming against my restraints. When he restarted it he made it very slow. In, out, in, out, in, out. The machine was starting to slowly fuck me. Ohhhhhhh. My asshole had become looser because of the constant tapping from earlier and all I felt was unbelievable pleasure as it opened me up.
The man came to the side of the table and poured the same massage oil on my chest and tummy; then he started to rub me. His hands were strong and skilled; whenever he reached my nipples he would pinch them. He was pinching and squeezing them as the machine was milking me slowly, tugging on my balls and fucking me. Ohhhhh damn. All I could do was moan uncontrollably as I felt unbelievable pleasure coursing through me.
