Steve continues to suck and lick his brothers overdeveloped cock as best as he could, unable to beak free from the strong inhuman grip of a baby, from the bulbous head down the thick shaft all the way to the base where his younger brothers large heavy balls sites, he worked away slurping trying to make him cum as soon as possible in the hopes to be released.
“Slurp…” “ Shlerp…” “Slurp…”
“Hahahhaaha“ “Geeheheeh”
Henry giggles and laughs to these new sensations, unable to comprehend what any of it means, only knowing that it felt good. Feelings an ordinary infant wouldn’t normally have but he had something he shouldn’t, an oversized fully-developed adult genitals. Genitalia that reacted the way any grown man’s would and worked overtime thanks to the genetic modifications made to him.
“Shlarp”… “Slurp”… “Gulp”…
“Twaheee” “Gahhaha” “Tehehee”
Steven was not as happy as his brother about this, giving a blow job to your younger but more endowed sibling is not fun. But his plan seems to be working because the euphoric expression on Henry’s face is slowly turning to one of longing despite the continuing laughing and steady grip on his head.
To confirm his suspicions the dick forcefully in his mouth feels more ridged and from what he can see between bobs the veins along the shaft are pumping bigger, almost flexing, The low hanging sack is pulling up and pulsing.
And then it happened, a salty eruption exploded out in his mouth with so much force he choked, thankfully at that moment Henry let go of his hair and Steven jumped back choking and gagging. Spiting out cum and trying to breathe, desperately trying to get a bearing while watching his brother in the midst of his first orgasm.
And an odd sight that was, Henry a baby squealing and gasping on the ground with a huge cock standing up in the air squirting semen all over the place. And just as soon as it started it was over, the adult organ slowly stop shooting and starts to droop, not going completely flaccid but still chubbed up and drooling. The large scrotum relaxing and laying on the floor heavily.
Steve steps over to Henry wiping his mouth and trying not to step in the cum puddles.
“ Well little bro I don’t know if I should be angry or impressed with you…”
Said Steve with his arms crossed looking down.
Henry seems to be in a sedated state, eyes glazed and a innocent smile on his angelic face.
“ Look at this mess I gotta clean up, the floors, me, you! And I have no idea what I’m going to tell mom and dad…”
Then Henry made an uncomfortable look on his face.
“Oh no don’t cry now things are bad enough as it is!”
Little dose Steve knows things are going to get more complicated. Henry Squirms and groans, the out of placed shlong twitching. But Steve notice’s something at the base of the monster, hair! Peach fuzz but definitely hair growing into a full bush and even the balls are sprouting fur! Now it truly looks like an adult weapon worthy of any porn star.
As if that wasn’t creepy enough the hair spreads up Henry’s belly and chest arms and legs even getting a beard, leaving a Henry looking like a mini lumberjack.
“Yikes”
Yells Steve unable to believe what’s going on. Little did he know he’s the one who jump started this transformation. The release of hormones from the orgasm has put the alterations in Henry into full operation, making the perfect soldier.
Henry’s whimpers start to sound different, deeper and gruff. In fact less like a baby and more like a teen, following the voice change Steve sees Henry’s body and limbs stretching out getting gangly and long his face contorting and bloating into a young man’s face, his body making gurgling and unsettling sounds, like bone and flesh ripping healing, organs growing. If Steve wanted to throw up from tasting cum earlier then he really wanted to now. Henry appears to be taller then Steve’s parents now at least 6’7 many 6’9 though he couldn’t tell since Henry is still on his back.
Now Henry looks like a tall skinny and hairy man.
“Urg” Henry almost yells
His voice sounds like a man’s now. His body convulses and muscles grow bigger, his arms flex up getting veiny biceps, his chest bulk out getting large pecs his nips pointing down to the sides a deep valley in the middle, abs popping out his middle down to his Adonis belt, legs thighs and butt expanding until Henry finally collapse on the ground looking like a sweaty hairy monstrous bodybuilder, eyes closed catching his breath deep and shallow.
Steve couldn’t believe it right where his baby brother was is now a giant of a man. Who’s now stirring, opening his eyes, sitting up and now looking at himself, his hands feeling up his body.
