Chad reached out and grabbed the bag of carrots. It was large, but his new strength made it feel unnaturally easy to pick up. He turned the bag over in his palms, paused for a second, and then looked towards the doorway to the hall.
He hurriedly shut the fridge drawer and door, and bounded hurriedly, but cautiously, past the room his oblivious brother was watching the television in, and up the stairs. He noticed as he went up how the movement of the flesh of his upper body lagged behind his legs, core and head. He took a sudden breath of pleasure as he watched his pectorals strain a he stepped then float up as he approached the next stair.
On the landing, he went where his instinct told him to first. Into the relative privacy of his room.
The rule had been no food in his room. But he knew that that was just for the nuts and the little bits of food that hid itself and attracted the mice. Carrots couldn't break apart and go missing very easily.
With his heart pumping, and his now 13 inch dick throbbing. He sat on the bed and looked at himself in the mirror again, staring into his features and checking every new corner and crevice on his body. His now too small shirt and trousers lay on the bed, while his underwear began to look uncomfortably small on his waist. And his dick stuck up out far from them. His softball sized balls peaked and wriggled out from the bottom, waiting for the slightest movement for them to ripple and show off their store.
He impatiently picked at the knot in the plastic bag, watching it slowly come undone. And finally, the bag lightly rattled as it's opening gaped out, presenting the carrots to Chad's face.
"Okay, cmon. Just one for now, and then we'll see how far we can push this." Said Chad in a whispery talk. Chad removed one carrot from the bag, and put the rest aside, towards his pillow. He took one bite, swallowed, and then a couple more.
Before long, he'd eaten the whole carrot, and the tingling sensation began to slowly return. His bicep, triceps and forearms began to expand again. Increasing in size slightly, right before his shoulders and pecs began to follow. He dropped his eyes into a swing across his chest, watching hid arms edge ever so slightly away, and his pecs began to take up even more room in his view, he felt them expand as he contracted and relaxed them. As he looked to the mirror, his legs were growing too. Even around the joints they began to thicken, they looked as sturdy as ever as he wiggled his toes to the strange feeling.
In one final act, his hard cock began to thicken and extend slightly, from around 13" to 16". Chad let out a slight moan and placed his hand on his already stuffed balls as they pushed and slipped out against his underwear.
Finally, it all came to an end. The growth wasn't as drastic, but for one carrot it was big enough.
He gaped at his new body in the mirror and played around with it for a bit.
"Wow, I wonder what I can do with this... and I wonder what eating some more carrots will do."
