Praneel was waiting for a change in his body, but after a few minutes nothing was happening. He felt silly wearing Danny's oversized boxers and with that weird gel covering his skin. He and Danny were getting worried that they have wasted 8 years of Danny's life until some noises started to come out from Praneel's stomach that caused him to groan in increasing discomfort. “Ugh!” Praneel groaned while he held his belly in hands. He suddenly burped and then his body finally began to stretch and expand. His once small feet and legs grew to large size 13 feet and immediately towered over Danny who was watching how his neighbor turned into a teenager.
When his legs and feet stopped growing, the rest of Praneel’s body started to grow to match them. His torso grew wide forcing some notorious pecs and abs. His arms were the next thing to grow as they stretched longer and formed some muscles on his biceps. Praneel’s breathing became heavier as his body went through a rapid growth spurt. His thighs inflated with some muscle which caused his butt to fill in the large underwear nicely, the fabric was even stretching a little from the muscular butt that Praneel formed. He kept showing signs of discomfort as his face restructured to that of a 16 year old guy. Stubble formed on his new chiseled chin at the same time hair grew on his pits and several pubes on his crotch. A coat of light sweat was present on Praneel’s overgrown body while he kept groaning in discomfort.
“Uuuh” He let out a deep moan as the underwear caused the final step to his growth. Inside of the boxers, Praneel’s small package suddenly doubled in size. His cock got so big that it almost bursted through the once large underwear but instead, it started to sneak out from a side. “Uuuh!!” Praneel moaned louder as his balls dropped and grew large and hairy, pushing his cock even more out of the now small boxers.
Praneel’s growth was finally complete. Where the once innocent 8 year old was, now there's an athletic 16 year old teen. Moments after his transformation, Praneel seemed that he needed some time to recover himself. Meanwhile Danny can’t take his eyes of the guy in front of him, especially at his large dick which head was protruding from a side. He was almost mesmerized by the sudden change on Praneel's body that he didn't heard his phone was ringing for a while. When he noticed it, it was too late. “Shit!” Danny said in childish voice as he realized that it was his father who was calling him.
While Danny called his dad, Praneel finally felt good, he was only wearing the tight boxers so he didn't felt to uncomfortable, however his new size made him felt a little bit clumsy and awkward. “Hey Danny!” He said with a surprisingly deep voice. “Can you give something else to wear?” The 16 year old said to the kids in the room who texted his father instead of calling back. “Sure, wow!! You even sound completely different!” Danny said while Praneel blushed a little in shame. He wanted to explore his body some more but without Danny around, some things need to do in privacy, he thought while his cock head thickened a little.
