Gay Erotic Stories

“What the hell happened to you?” said Bill, as he opened the door to his best friend, Johnny. He hadn’t seen Johnny for days, and now, he appeared at Bill’s house. “You look so different! Where did those muscles come from?” His friend was nearly unrecognisable – his t-shirt was tight, and his shorts barely covered anything. “Let me in,” said Johnny, “I’ve got something to show you”. Bill noticed Johnny’s eyes were glazed, and he looked a lot older. But he was curious, and worried for his friend.

“Come in before somebody sees you, but be quiet, dad’s asleep in the living room”. Johnny strode passed him, nearly knocking him down. He went straight upstairs to Bill’s bedroom. Bill followed him up.

“Do you want to be like me? The things I know, the power I have. You can have it. I want to share it with you,” said Johnny.

“Are you on fucking drugs? What’s going on, you freak?” Bill whispered. He saw that Johnny was feeling his crotch through his shorts. Bill’s eyes widened as he saw John’s cock swell through the material – it was huge. “What the hell?” said Bill.

Johnny looked directly at him, making Bill uncomfortable. “I’ve undergone a change, as you can see. It’s amazing. It won’t hurt, we can show others. You just have to trust me”.

“Fuck off!” said Bill, and turned to leave the room. But the door closed by itself. Panicking, he tried to open it but it was stuck. He turned back to Johnny, who had taken his clothes off. Bill was impressed and scared. Johnny was a 9 stone weakling until today, now he looked strong. His dick was enormous. Bill had never seen it hard before, but he was sure it didn’t used to be that size. Johnny walked over to him and stroked his face. “Get the fuck off me!” said Bill through gritted teeth, and tried to push Johnny away, but he didn’t budge. Johnny kissed him, and reached down to his friend’s crotch. Bill felt himself get hard, which he tried to stop, but Johnny knew what he was doing. He unzipped him, and pushed his jeans and pants down. Bill’s normal size cock sprang to attention, and Johnny took it in his mouth. Bill had never been sucked off before, and he found himself thrusting back and forwards in his friend’s mouth. “St…Stop it, John, what’s happening?” Johnny stood up, and flexed his muscles. Bill slowly reached out and felt his friend’s arms. He just couldn’t believe it was the same boy.

Johnny took him by the hands over to the bed. He sat on the edge, and undressed his friend. Bill tried to resist, but it didn’t work. “John, you don’t want to do this, you need help,” he said. John merely smiled. He gently wanked Bill off, and brushed his nipples. “Fuck, I’m gonna cum, ah, ah, ah!” said Bill, as he came over Johnny’s chest. Johnny smiled, and raised his wrist to his mouth. Bill saw small fangs grow in his mouth. Before he could say anything, Johnny bit into his wrist. Bill nearly threw up; he thought his friend had gone mad. Johnny stood up, and pushed his wrist into Bill’s mouth. Blood seeped into his throat, and the change began.

It was different to Johnny’s change. This time, it started in Bill’s cock. Even though he had just cum, he felt his balls fill up. He looked down and saw them swell, to the size of lemons. His cock, which had just got limp, shot up and grew to twice its biggest length. It got thicker and thicker, and Johnny took it in his mouth again. Bill’s muscles grew, as Johnny’s had done. His limbs trembled as the change took place. He was naturally stockier, and it became obvious that he would surpass Johnny, as his muscles expanded beyond his friend. Suddenly, the door flew open, and Bill’s dad stood in the doorway, open mouthed. He saw his naked son shaking, muscles growing in front of his eyes, while his best friend was sucking his enormous dick. Blood trickled down his son’s mouth, whilst his eyes glazed over in delight. He ran over to separate them, when they both looked over to him. He froze, unable to move.

Bill’s transformation was complete. He was a fine specimen of man, his chest broad and powerful, and his legs firm and muscular. He looked at his dad. “Join us, it will feel wonderful,” said Bill. “Son, whatever the fuck is happening, walk over to me. I’m getting you out of here!” his dad said. But instead he found himself walking over to the boys. Bill undid the buttons on his dad’s shirt, and took the shirt off. His dad had quite a gut, but he was muscular with it – he used to be a rugby player. Bill bent down, and licked his dad’s nipple, whilst Johnny unzipped him. Although no match for their massive cocks, the older man’s penis was nicely thick. He looked down in horror, as his son’s friend licked his bell-end, and devoured it in his mouth. He quickly got hard. He couldn’t fight them off, he tried to push his son away, but he didn’t flinch.

Bill went behind his dad, and licked the hairy arsehole. His dad whimpered, tears coming down his eyes. Bill gently fingered the hole, slipping a moist finger in. His dad gasped, as his son found his prostate. Bill smiled, as his dad pushed down on his finger. Meanwhile, Johnny turned over, and bared his muscular arse to him. The man’s cock was slippery with saliva, and rock-hard. He found himself ram his cock into the welcoming hole. Johnny grunted with delight, as his friend’s dad fucked him ferociously. After a while, Bill pulled his dad away, as Johnny leapt up. They both pushed the man onto the bed, his cock still hard and glistening. Johnny squatted over his cock, as Bill pushed his massive dick into Johnny’s arsehole; father and son pounding him again and again, again and again. Johnny laughed, as he was pulverised by the two men. Finally, the father grunted, as his cock exploded in Johnny’s hole. Johnny turned around, as Bill continued to fuck him. Soon, they both came, the bed drenched in spunk.

The older man sat on the floor in a daze. He was drained – that was the best sex of his life, but his brain told him to be repulsed. He looked up to his son. Bill was stroking his muscles, as Johnny sucked his cock. The dad slowly got up off the floor, and walked over to the boys. “Change me”. His son smiled, and brought his wrist to his mouth.

The neighbours heard a ferocious roar, as the gentle giant whom they had known for years, turned into a muscular beast. The noise that followed was unholy, like hell had opened up, an orgy of demons copulating. The police arrived and broke into the house. It had been torn to pieces, and the smell of testosterone and sex brought tears to their eyes. The only thing left standing was a mirror in the main bedroom, not a scratch on it. PC Jones found himself drawn to it. He pushed his face onto the surface. The constable looked over to his colleague, and licked his lips.

The End?
