Jim and Cody in the bedroom
"What the heck!" exclaimed Cody. He ripped his t-shirt off his body, as it was impossible to fit over his torso and arms.
Huge muscles were revealed. Jim locked the bedroom door. Cody managed to squeeze out of his board shorts with only a few threads popping.
Cody stood naked, and he was a bodybuilding god.
Jim stood next to him in the mirror.
"Take off your clothes, Jim!" said Cody.
Jim kicked off his shorts and shirt.
Cody was 210 lbs of muscle compared to Jim's 110 lb frame.
"Wow!" said Jim. "I wonder…" He grabbed the balloon. "Control how gay and horny Cody is!" And he blew the balloon full of air, breath after breath. "Release!"
And Cody's giant boner grew huge and his muscles even more subtly beautiful and proportioned and his skin creamier and his eyes more beautiful and his hair gelled and styled… His butt stuck out a few more inches, too.
Cody was overwhelmed. He turned on Jim. "No!" said Jim. "You're too big for me!"
Cody plucked the balloon from Jim's hand. "Control how much of a hung gay muscle bitch twink bottom Jim is and how gay and horny he is and how big he is and muscular too!"
He took a deep breath in his giant muscle chest and blew. All at once Jim changed all over. He became taller and his muscles swelled, especially his butt. His cock bloated and drooped fantastically heavy over monstrous big balls, and Cody blew again. Jim swelled until he was almost as tall as Cody, but his muscles were more defined and sexy compared to beast-like Cody. Jim panicked as he felt the changes hit him, changes he couldn't avoid.
Cody blew into the balloon again, making it swell almost to bursting. "Release!" he said.
Jim felt his body changing, his mind changing, his penis lengthened in seconds, swelling thicker all the while, and his testicles grew even bigger than Cody's monster balls. His muscle ass swelled into a muscle bubble butt that ached for cock. Jim shuddered as the desire hit him. His muscles swelled bigger and stronger, his skin was smooth, but he was not taller than Cody but not nearly as muscular. Cody dropped the balloon and started kissing Jim furiously and passionately. They both swooned. Cody's giant monster cock was dripping pre cum and he used it with a forefinger to lube up Jim. Jim swooned and his cock swelled aching, giant and hard with the sensation of anal stimulation.
"Cody you have to fuck me!!!!"
And Cody pushed jim back on the bed, posed a most muscular which made Jim gasp and shiver, and hen rubbed his cock on Jim's bubble butt. Seconds later he was thirteen inches inside of Jim, who was sweating and gasping and hitting at Cody's brutal hairy muscle covered with dripping sweat. Jim reached over, gasping, and grabbed the balloon from the floor. "Control the size of Cody's cock… ungg…and how long he can stay hard and how much he can..ummnnnn cum!" He blew, panting into the balloon, and Cody's cock swelled so much bigger he cried out with pleasure. He blew again and cried out with pain that turned into sweet pleasure. "Release!!!" cried Jim.
