Nothing could've prepared Jamie and Charlie for the sight that beheld them when Timmy opened the door from his room. Rather than being the pint sized muscle boy he had been when he had entered it, he now towered even over Charlie, who stood 5'10. And he did not look happy.
"Alright, so heres the deal squirts, You're not gonna fuck with me any more. Jamie, I'm the older brother now, no questions asked. If you step a fucking toe out of line I'm going to beat your tiny ass into oblivion. As for you Charlie, when we go back to school on Monday you better stay fucking clear of me and the bitch you've been dating or I'll make you watch me fuck her pussy, and lick her clit till she screams my fucking name. Are we clear?" Timmy's now even deeper voice resonating through the house.
Both boys, astonished by the once innocent seven year olds behavior, and his language, only nodded in consent.
"I SAID ARE WE FUCKING CLEAR YA LITTLE CUNTS?" Timmy roared, veins popping out on his neck and forehead, his face turning red.
"Y-y-yyess, we're clear" Both Charlie and I said in unison, staring up at Jamies once small brother.
It was then then that all three of them noticed some continuing changes in Timmy. His arms started to fill out more, his legs straining against the fabric the once large gym shorts he was wearing. "AGHHHHH FUCKKKKKK!!!!! I'M GETTING FUCKING BIGGER!!!! OHHHHHHHGOOOOOODD!!!" Timmy moaned in approval. We both watched as Timmy shot up another four inches in height to look like a behemoth at 6 foot 6. And the muscle appreciatively added on. But that wasnt the only thing that changed. I saw hair start to dust his chest, legs, arms, and face. Blond to match that on his head, except that which was trailing up from the unmistakable bulge in his shorts, a slightly dirtier blond.
Now he looked older than the sixteen he had when he opened the door, at least eighteen.
"You shitstains look downright puny next to me now. Do either of you have hair on your chests, hell Jamie you still look like youre twelve, have you even gone through puberty?"
Jamie stared down at the floor.
"Timmy I----" Jamie was unable to finish his sentence has Timmy thrust his once older brother against the wall.
"It's Tim. Get it right, or ill woop your ass"
"Tim, a-a-a-are you hungry. Do y-y-y-you want food?"
"Thats what I like to hear. How about the two of you prepare breakfast for me, and Charlie how about you invite that nice piece of ass over so I have someone to fool around with."
As Tim swallowed down the last bites of his sixth plate of food, Carrie, Charlie's now ex-girlfriend walked through the front door, and eyed him appreciatively, as he only wore a very tight fitting pair of shorts, with his looming shoulders, big arms, and broad chest and back on display. She quietly placed herself on Timmy's lap, and Charlie and Jamie watched in wonder, as he took her right there on the dining room table. She screamed, and he moaned as she whispered dirty things into his ears. When he came his muscles had another spasm, and seemed to grow a smidge. Not enough for him to notice, but enough that both Timmy and Charlie looked at each other with the tiniest bit of apprehension.
