Gay Erotic Stories

My name was Johnny. I came from a nice, safe suburban home. I had just turned 18 and was in the middle of my exams. A gawky, tall boy with little muscle and a small dick – a late developer and perpetually horny. I had been having weird dreams – of men fucking, rituals and strange-looking creatures for months. I kept seeing images of something, a glimpse here and there whenever I saw my reflection. It looked the creature from my dreams, with huge muscles and horns. I put it down to exam stress and boredom. But I found myself wanking off far more than usual. When I tried to ignore it, I felt as if it would explode. I needed a girlfriend or something to fuck, fast. That was until last month.

I had just climbed into bed, after yet another wank, when I heard a slight noise in the house. I opened his eyes and looked around – and I heard it again. It was like a very distant tinker – the sound of glass breaking. My parents were away for the weekend, and I was beginning to get scared. Deciding to investigate the house, I got out of bed and reached down for my cricket bat from under the bed. I was wearing boxer shorts and an old t-shirt. The house was cold, and I was shivering. I opened my bedroom door and looked down the landing to my parents’ bedroom. I could see the slightest sliver of light around the door – barely noticeable. Ignoring my nerves I stormed down the hallway to the bedroom, cricket bat above my head, and kicked the door open. But the room was empty – no sign that anyone was in there, and none of the lights were on.

I was about to leave when I glanced at the full size mirror in the corner. A large and muscular creature – the one from my dreams- looked out at me, licking its lips with a long and thick tongue. Its eyes shone with a yellow light, as it sneered at me. It had a massive cock, which pointed out directly at me. Its tail wrapped around its body, and its fangs glistened. It had sharp horns all down its arms, and on its head. I heard the noise of breaking glass again, and was overcome with a stench coming from the mirror. The demon started to walk through the glass, but it didn’t break. I remember I felt sluggish, and couldn’t move no matter how hard I tried.

Shaking with fear, I gasped as the demon escaped the mirror, only now it seemed more human – still impossibly large and muscular, but definitely now a man with small horns sticking out of his bald head. The smell was even stronger now. He stretched his arms, and flexed his massive chest. He looked down at me. I was paralysed with fear, but I also didn’t want to move. I looked directly back at him. He didn’t say anything as he moved down and clamped his lips on my mouth. I felt his tongue enter my mouth. It was so big; I could feel it down my throat. I couldn’t breathe. I tried to move my head away, but the man held me between his massive hands. He forced my head down to his nipple, and pushed it into my mouth.

Something in my head clicked, and I suddenly bit it. I felt warm blood spurt into my mouth. It tasted delicious, like nothing on earth. I felt myself shaking as it went through my body, like I was having a fit. He released my head, and stood to the side, allowing me to see my reflection in the mirror. Eyes wide, I grunted as the blood released a strange power through me. The front of my t-shirt suddenly got tighter, and I could see an outline of chest muscle straining through. My arms started to swell, filling the space in the sleeves. I flexed my chest and arms, and pulled the ragged t-shirt from me. My stomach used to be thin and shapeless, but now, it became defined, with a taut six-pack. My shoulders and back expanded with muscle. I kept shaking as my boxers started to tighten as well. My thighs and calves grew hard; as the fabric started to give way. I could see the outline of my penis in my shorts, as it began to grow. I got a hard-on, but it went way past what it usually grew. I could see my cock-head stick out the bottom of my shorts. It grew so big, bigger than anything I had seen in the changing rooms.

My boxers got tighter and tighter, as my cock got harder and harder. It tore through my shorts, and I yanked them down. My dick shot up, and I saw a pair of hairy, low-hung balls. They had gotten big too. I felt my new body all over, my hard arse, the veins on my legs, the heftiness of my chest. I looked in the mirror and saw an athletic body, better than those bastard rugby players at school. My cock was rock-hard, I needed to cum so badly, and I grabbed it with my fist and wanked hard. I barely noticed the man, until he got behind me and squatted down. He forced me to bend over, and started to tongue my arse. I remember whimpering, as his long tongue went inside me. His hands went to my nipples, and twisted them. I loved these feelings, and I wanted more. He sat on the bed, and pulled me onto him. I thought it would kill me, that giant cock, but it went in easily. I could open my arse to take anything, as I later found out. I still remember that feeling – of being fucked by this animal. He pushed up into me, as I pushed down onto him. The power in him, and in me – it was a superhuman fuck. His cock went so far into me; it was like I could taste it.

Still inside me, he pushed me onto the floor, and pounded me. My cock was dangling from side to side, the hardest it had ever been. We fucked for hours, maybe days, the cum building inside both of us, waiting to explode. I saw us in the mirror – his face grew more demonic, as wings sprouted from his back, and a tail erupted from his lower back. His mouth and nose grew into a snout, as he growled and snarled. His muscles swelled even more, and horns pierced through his arms and shoulders. His cock filled me up completely, as I felt my body change as well, new muscle growing again. I felt the strength in me multiply ten-fold. My skin stretched, as the muscle kept growing. We reached breaking point – I came before he did, my balls shooting a ton of spunk out of my cock, splattering the mirror, which absorbed it immediately. He ripped his cock out of me, and wanked himself ferociously. A gallon of his cum exploded over me and the mirror, which again absorbed it.

We both collapsed, our bodies returning to their normal state. I thought I had changed back to my old, gawky self, but I could see that my new muscular body was still there, glistening with sweat. Before I could say anything, he stood up and walked to the mirror, disappearing into it. I had been given a gift, this body, and an uncontrollable urge to show others the way. I started with my best friend.
