Gay Erotic Stories

I woke up in strange surroundings – it looked like a hospital ward. Around me, surgeons in gowns and masks prodded me with small, thin needles. My whole body was covered in them, as a nearby machine delivered small electrical charges through them. It felt like there was something in my arse – it seemed quite small, but it was pumping in and out. What the hell was happening to me? My demands for answers were ignored, as they continued to perform their procedures on me. Although I was awake, I didn’t fell any pain, but I was very uncomfortable. I looked down to my chest, and saw a fresh scar running across my left pectoral. I was terrified and angry, but I tried to work out how I ended up here, but I simply couldn’t remember. I was too drugged to resist – not that I had much choice as I was completely outnumbered. “Increase the voltage, I want to see how far we can take this one”, said one of the surgeons. Suddenly, the electric shocks became much more intense – my muscles were contracting involuntarily at an incredible rate. I was twitching uncontrollably, as the electric shocks brought me to the most intense orgasm I have ever had. The surgeon bent over to my face. “You haven’t felt anything yet!” as I lost consciousness.

I came too in a dark room, sitting upright in a metal chair – it seemed more like a dentists’ chair, but I was bound at my neck, arms, waist and legs. I was completely naked, and had been shaved all over. I had also been hooked up to a drip, and electrodes were over much of by body. I was scared and getting increasingly angry. A man in a medical gown came into the room. “What the fuck are you doing to me?” I said, through gritted teeth. “Have you ever wanted to be more than you are? To make the full use of your potential,” the doctor said. “Of course I do, but I could have done without the medical torture, you bastard!” He merely smiled. “Watch this screen please”. Images of naked men began appearing in quick succession. I had heard of this kind of thing before, I think it was called conditioning. “I’m straight, and if you’re trying to turn me, it ain’t going to work”. Again just a smug, creepy smile. “Whatever, have you got any popcorn?” I said sarcastically.

As I watched the images, they became more pornographic. Scenes of men wrestling, oiled and sweaty, orgies, fisting, bondage, pissing – everything you could imagine. The doctor increased the dosage of the drip, as the electrodes delivered mild pulses through my body. Something clicked in my head, as I found myself responding. I felt my cock stir, and swell, as I pictured myself in the images. “The subject is responding, activate the implant”. My chest twitched; suddenly I felt my blood rushing around my body. “Before you ask, that’s testosterone, and your body may undergo some changes as well”. I couldn’t hear him; my heart was pounding as I began sweating and grunting. The doctor left the room. The screen showed increasingly powerful images of men fucking; I could practically smell it in the air. I looked down at my cock, which was fully hard – about 6 inches. It wasn’t enough – a jolt of electricity shot through me. It kept growing, becoming longer and fatter. It shot up to reach my stomach. My balls grew heavy and large as well. That wasn’t the only change – I heard a cracking noise as the muscles in my thighs swelled. My calves grew as well, as the restraints started to buckle. I felt myself lift from the seat as my buttocks became hard and round. My forearms suddenly expanded, as did my biceps. My chest began to jut out, as a deep cleft formed between my pecs. My neck grew thicker, as my shoulders bunched. All the restraints buckled. My blood was boiling. I roared and flexed my new muscles, as I frantically tried to free myself.

The door opened, and two guards pushed a naked man, who was chained at the hands. The man was powerfully built, and, like me, completely hairless, apart from a close crop. His expression was more feral than human. Before leaving the room, one of the guards approached me, and withdrew the drip and removed the electrodes. The restraints withdrew into the chair, and I was free. We both flexed our muscles, as our cocks strained at each other. I sniffed the air, and began circling him like a wolf with its prey. His body was impressive. Taut muscles rippled under his skin, his cock sticking straight out. I launched hungrily at him, and savagely kissed him. He forced me down on my knees, to suck his powerful cock. It was the best thing I had ever tasted. I reached up to play with his nipples. He moaned, as I furiously sucked his hard cock. He turned around, and I stuck my tongue up his hairless arsehole. All that I had seen in the conditioning had taught me well; I was a natural. But after a while, I became increasingly aware that this was not I – something was controlling me. I stopped rimming him, and looked around confused. Suddenly my chest twitched, and I felt a new surge of testosterone. My muscles expanded, and my cock grew another inch. All doubts left me, replaced with only one thought. “Fuck me, fuck me hard” He turned back around, and lifted me up by my arms. He clamped his mouth over my cock, and took its full length. I groaned as I felt close to cumming. I pushed his head away and looked down at him. We didn’t need to speak; we could read each other’s minds. Pushing me against the chair, he spat on my arsehole, and rammed his cock up me.

I had never been fucked before, but it went in with little resistance. Everything told me this was right; that this was meant to happen. He pounded me into submission, sweat glistening on our engorged muscles. I didn’t take long to cum. Suddenly, I jolted upright, and felt my whole body climax. Energy shot through my muscles, as they expanded threefold. I shot a huge load over the chair. Behind me was a furious raw, as he exploded inside me, and I felt my rectum drowned in cum. But I wasn’t finished. My balls immediately filled up again, and my cock, already dripping, became fully hard. I whipped around, and pushed the man onto the floor. He turned around on all fours and bared his hole to me. I spat at my cock, and savagely penetrated him. I thrust harder and harder. It didn’t take long; I filled him with my cum, as his cock shot out again and again. We both collapsed, exhausted and covered in sweat. I felt some of the muscle that I had gained during sex had drained away. My body had returned to the point where it had first changed. I lost consciousness again

Part 2 – 1 week later

I woke up in my bed, back in my own flat. I was completely disorientated. I had no idea what day it was, or where I had been. I thought briefly that it had been a weird dream, until I looked down at my body. It was as muscular as I had remembered, and still hairless. I leapt out of bed and ran into the bathroom. I looked at myself in the mirror. My chest jutted out proudly, as I flexed my biceps. My cock quickly grew to its new length of 12 inches. Something inside wouldn’t let me question what had happened to me. I just knew it was right, and to accept it. I had the urge to fuck men ingrained into my head, and nothing was going to stop me.

I ran back into the bedroom and instinctively jumped out of the window, stark naked. I landed effortlessly on the lawn. Again, this seemed natural, that I could survive a jump of considerable height, without a scratch. It was the middle of the night, and the streets were empty. I quickly left my small town, and strode through the countryside, at a speed that was surely super-human. Striding through fields and woods, I felt at one with nature. I soon found it easier to run as an animal would; on four limbs. My old life meant nothing. I was something new.

It didn’t take long to spot my prey. A police car had pulled up on the side of the road I couldn’t see the driver, but I could smell him. He was taking a leak. I followed his scent and watched him as he shook his cock. He wasn’t in the best of shape, but had a chunky, manly look about him. About 40ish, I could smell his musk in the air. I walked up to him, and allowed him to see me, fully naked, and rock-hard. “What the fuck?” he said, as he rushed to me with his baton, ready to arrest me. I leapt over him, and landed several feet behind him. Before he could work out what was happening, I ran up to him, picked him up and threw him back down a short dip into a field. I pounced onto him and licked his face. “What are you going do to me?” he said, trembling. I merely grinned. Forcing him to crouch, I pushed his head on to my cock. Fucking his face roughly, he was struggling, but was no match for my strength. I hoisted him up and ripped his body armour off. I kept staring into his eyes, which drained him of all resistance, as I tore his clothing off. His body was hairy, and had quite a gut, but his muscular chest and arms compensated this. I sucked on his nipple, as I whipped his belt off. I pulled his trousers down, to see his boxer shorts jutting out. He was completely submissive now. “Take your boxers off,” I ordered. He did as he was told. His cock was a pleasing size – not huge, but had girth, and a mushroom head.

I took him in my mouth, and played with his nipples. He groaned in pleasure. I could tell he was going to explode soon, so I stood up. “I’m going to fuck you, and you’re going to love it. It’s not going to hurt – you’ll feel yourself opening up and taking it all” He grunted yes, and turned around. I licked his arsehole, fingering him to loosen up. He pushed back on my finger, as I tickled his prostate. I knew he was ready for me, as he relaxed his hole. I entered him, my cock swelled to its new enormous size. He clamped around it, as I began pumping him. In the middle of a field, the dead of night, we made as much noise as we could. He took to it well. We changed positions, me lying on my back as he bounced up and down on my cock. He suddenly groaned, and shot his spunk over my chest and face. This brought me over the edge, as I came repeatedly. He fell off, exhausted and confused. It slowly dawned on him what he had just done. “You’ve just realised some of your potential. I’ll come looking for you if you haven’t started to explore some more of this. I’ve got your scent now, friend”. I got up, and sprinted off in the direction of the next town. I was more than ready to find some new men to have, and to see how far I could take it.
