…to your little brother Jim’s room.
As you entered it was its usual interior. Toy weapons, nerf guns, Lego and a single football filled the room, together with Minecraft and Fortnite posters and relics, and a newly addition priced skateboard as your little brother had become recently somewhat of a skater boy.
From a racecar bed your scrawny, little, blond haired brother rose from the sheets looking like had had woken up from a shock.
His long blond hair, rained down on his face as he gasped after air, looking at you entering the room with amazed eyes.
“Big brother, I’m feeling weird.”
Suddenly he hiccupped, whose pulse through his thin little body caused Jim to expand a little right then and there in front of you, making you look at him in disbelieve.
“What happened?” he hiccupped once more and grew once again in size. “Wow…. I grew!”
Jim stepped out of his bed, which was now smaller than before, facing his brother at eye level, standing in his undies, that was tighten around his junk, and with a third hiccup it began to strain and Jim had now passed his big brother in height.
“This is *hiccup* cool!” Jim said, growing even larger.
Not understanding how this was possible, you slowly backed up while trying to contain the problem: “Jim, listen to me, you got to stop hiccupping.”
“I can’t *hiccup*” Jim responded, his underwear ripping off to reveal his uncut, hairless boyhood: “It just feels so good *hiccup* and I always wanted to be a big boy!”
Jim now began rubbing his belly with a painful facial expression. “Oh, my tummy… I can feel a big one coming up… uuuh.”
You panicked and ran out as the rumble of hiccups begin you began to emerge louder and louder, while feeling the house give away from the growing mass inside of it. Pulse after pulse caused the little boy to grow and grow, exploding out of the house finally, now a naked teenage giant with a towering forty-foot height.
