While Wendell was peacefully asleep, the puberthere was doing its job on his body, just like Wendell has planned it. Wendell’s body looked as though it was inflating, as his body stretched and widened his clothes began to shrink. His arms and legs began to swell like balloons, starting to shred the seams of his former baggy clothing. Wendell’s legs stretched towards the end of the bed as he gained height while his feet quickly grew to large size 15’s, too big for his father's size 12 shoes he had taken from his parents’ room. Wendell seemed to be deeply asleep because he was completely unaware of his rapidly growing body.
After a few hours, Wendell's body seemed to stop stretching, instead his body continued to widen. His chest was pushing down the front of his wife beater when large hairy pecs began to form, at the same time his stomach started to form a nice set of abs. While this was occurring, Wendell’s shoulders began to widen and form large muscles that gave him a manly v-shape. Wendell now had the torso of a man, but he still had a kid's face. However that was already changing as his face began to age through 12 years quickly. It become chiseled and form a nice patch of facial hair along his jawline and face.
While all that was happening in his top half, his bottom half was getting some drastic growth as well. Wendell’s thighs quickly got thick with muscle to match his size 15 feet. Inside his boxers, Wendell’s balls started to push from underneath, in no time they became exposed and inflated to chicken egg size. His dick was also growing rapidly as it became thick and long to a size of 8 inches, soft, his uncircumcised foreskin wasn't as loose as before and it partially revealed some of his swollen purple mushroom dickhead. Once Wendell’s transformation was complete now there was peacefully sleeping a 27 year old large and muscular man in place of the once peacefully sleeping small 15 year old teen.
The next morning came, and Anthony awoke from his peaceful sleep when he immediately noticed something off. At first he thought he was still dreaming, but a quick pinch to his left arm made him confirm he wasn't still sleeping. The morning sun beams were lighting directly to the puberthere and he recognized the device from a video he saw last night. He knew what the puberthere does and he started to connect dots about his brother's weird behavior last week and his insisting for that sleepover. He jumped out of his bed, making a loud thud on the floor and looked at Wendell's bed where he saw a large man sleeping that reminded him a lot to his father. He knew that man was Wendell, so he crossed arms and shouted to wake him up from his still peaceful sleep.
“Oh good you’re awake!” Anthony said looking down at Wendell. “Who?! Who are you?!” Wendell said with his new deeper voice, while he noticed the tattered fabric on the guy's shoulders. “Anthony?! Is that you?!” Wendell was in shock as she gazed upon the now 21 year old hunk that resembled his 9 year old little brother, he can't believe how much Anthony looked like his uncle now. “Oh! I know what you did and mommy isn’t going to be happy when she sees us like this! You’re going to be in big trouble!” Anthony said while he kept his arms crossed.
“Hey! Why are you looking at my pee pee?! I’m talking to you!” Anthony scolded his brother as Wendell stared at his little brother throbbing dick and hanging hairy balls. He can’t believe his eyes, Anthony has an adult set of dick and balls, even a thick bush of pubes that goes up and connects with a hairy chest. He was surprised of gazing at such an attractive man now. He thought to herself, “How did this happen? It's supposed Anthony is in his best friend's sleepover”.
“Hey! Why my pee pee is so hard and pointing up? Can you help me to turn it soft like yours. It feels weird to move like this!” Anthony said while he started stroking his dick and playing with his hefty balls. “Haha, this tickles…I didn't know big boys had hair in there, I've just seen the ones in your armpits.” Wendell blushed but didn't reply. “Can you help me find some clothes, so I’m not all naked anymore?” Anthony said flexing the muscles in an arm while he kept feeling his balls with the other one. “S-sure! I can give you some of dad’s.” Wendell had to change his own clothes as well, he didn't expect he would get so big and he also needed some distraction from the sight of such an attractive man pleasuring himself right in front of him.
