Bruce groaned as his foreskin slipped up over his sensitive cock head, finally in place. The he looked at Andrew's huge flaccid penis and decided to take pity on him, after all he was his little brother and he loved the kid to death, no matter how annoying.
"I wish Andrew had his foreskin back, but large enough to cover his entire penis." He wished, smiling as Andrew grunted and the huge penis was suddenly engulfed in a soft sheath of skin. Bruce groaned watching, rubbing his hard 8 inches.
He put a quarter in the machine and got the card, wishing this time that anything and everything he wished for would come true without costing him anything, and that all the wishes were specifically controllable by him, and the powers didn't take things literally, like they warn about in all those old movies he watched. He could wish for anything, even alter reality, and it would bend to his will.
Bruce groaned and felt his dick twitch at the mere thought of all the power. He turned back to andrew and tested his new powers out.
"I wish that Andrew's dick would grow another foot, and that while it grows it's one of the most intense and pleasurable things andrew can feel, inch by inch." He groaned watching his little brother writhe. Andrew started panting and felt his dick tingling, all the way down to his massive balls.
"Oh ohhhhhhh. Bruce! Bruce it's coming! My penis is growing!" He moaned and tutted against the air, hardly able to move for his bean-bag sized balls. Bruce smiled and rutted into the air as well, his 8 inch cock leaking a large amount of precum already, making the sensitive foreskin slick. He moaned and nearly nutted as Andrew finished growing, seeing a small amount of shiny precum work it's way out of Andrew's slit. Oh.
"I wish Andrew's body and organs were able to handle his enormous penis and testicals, without modifying his body. I wish his prostate was stronger and more powerful, and ten times more sensitive, and his heart was powerful enough and he had enough blood to sustain his erections." Andrew squinted as his brother wished for these things, his twelve years of life hadn't really prepared him for all the intricacies of sex. He suddenly felt stronger however, and could breathe better, the ache in his chest that he hadn't really been paying attention to went away quickly and he looked up and grinned at Bruce, then lunged forward and moaned loudly as he felt a gush of something from inside his balls. He whimpered and humpped the air, Bruce watching and groaning himself as at least half a gallon of precum drooled out of Andrew's huge penis.
"Oh, Andrew. God that's hot." Bruce groaned and rubbed himself, stepping closer to Andrew's cockhead. He masages the sensitive skin and groaned as the slit of his cock opened to drool out more precum. Bruce was so turned on.
"Andrew... Oh oh god... Oh, can... Can I fuck your penis slit?" He whimpered, nearly cumming from that sentence alone. Andrew groaned as well and decided it would be ridiculously hot to have his big brother fuck him in anyway, especially in a way most guys would never get to enjoy. He nodded his head and yelled with pleasure as Bruce stuffed his 8 inches into his pee slit.
"Oh, oh god, it's so wet!" He keened, shoving himself in and out of Andrew. Andrew howled in pleasure, the 8 inches not going anywhere near filling him up but the foreign feeling alone almost pushing him over the edge.
Bruce groaned and wished, suddenly, that his penis was longer than Andrew's, growing pleasurably with each thrust, but still skinny enough to fit comfortably into his cock.
"Oh, and with the necessary modifications to my body too, so my organs can handle it." He tried out the wish, and was proven of it's usefulness as he felt his body become stronger, and his cock began growing inside of his little brother.
"Oh, oh! Bruce! BRUCE! Oh! Your pe-penis... Oh it's getting bigger!" Andrew moaned and humped as much as he could back into his brother, masaging the fleshy skin of his huge testicles with his hands. He felt his brother hump faster, thrusting in and out while moaning, his penis beginning to snake down into Andrew's penis.
"Oh it is! Oh it's huge!" He moaned, still thrusting. "Uhhhh, I'm in your balls! I'm in your balls!" He groaned and sure enough there was a large rounded object poking out at the skin of Andrew's left nut, thrusting in time with Bruce. Andrew rubbed his palm against the Bruce's cockhead, giving them both a sense of extreme pleasure.
"Oh! OH! I'm going to cum! I'm going to cum in your balls! I'm going to cum in your balls Andrew! Do you what me to? Oh, do you want your brother's sperm in your balls?" Andrew whined and nodded, feeling his huge penis twitch.
"Cum in my balls Bruce! Cum in them! Fill my balls up with your hot sticky juice! Oh I'm so turned on!" He moaned out, the almost ridiculous begging turning both brothers on even more.
"Oh... Ohhhh, I wish I had huge balls! Big balls so I can fill my brother up with my speem and then he can cum my sperm out! Ohhhh!" he shouted as his balls suddenly filled out, from large eggs, to baseballs, to grapefruit size to softball then almost as big as Andrew's, hot and full of sticky cum. He thrust harder and deeper, moaning Andrew's name.
"Oh Andrew, oh Andrew, oh god! I'm gonna can in you! I'm gonna cum up your penis! Oh Andrew, I'm gonna shoot it, I'm gonna squirt it in your big testicles, little brother it's going in you I'm squirting oh I'm squirt, squirt, squirting.... I'm cumming I'm cumming here it CUMS!" Bruce babbled and came inside his brothers testicles, making Andrew jump and jerk, moaning as he had a penis enema.
"Bruce! Oh oh! BRUCE! CUM IN MY BALLS!" He shouted loudly and then came himself, ejecting Bruce forcefully from his penis as his and his brother's cum flowed in gallons out of him.
Both brothers panted, overwhelmed from their orgasms. Bruce, the responsible big brother, wished they were both clean and back to a healthier size, and their bodies modified to fit that size. He shrank back to a nice and hard 8 inches, his testicles back to their normal size, and then watched as his hard cock went to a good five inches soft, foreskin slipping over his cockhead, which was oversensitized from the previous activities. He sighed and saw his brother's pranks settle back into to a more comfortable and appropriate seven inches, before becoming soft and shrinking to about four, his newly acquired foreskin protecting his oversensitized glands as well.
His testicles had returned to a more appropriate size too, and they both looked at each other, wolf grinning.
Bruce wished up a blanket for Andre and wrapped him up in the blanket, smiling as Andre came and sat his his lap.
"That was amazing." He said simply, and Bruce had to agree. He smiled and looked at his brother thoughtfully.
"I wish Andrew also could wish for anything he wants, just like I can, except if it's really too dangerous or gets I can overwrite it." He said and Andrew felt his entire body tingle from the power his brother had just granted him.
They grinned at each other and Bruce threw his arms around Andrew. "So little bro? What do you want to do next?"
