Brian soon arrived at home where his younger brother Kebin was waiting for him and noticed that he had a special blue drink.
"Hey what's that?" Kebin asked.
"It's a special drink that can solve our problems. A magic lady gave it to me." Brian answered pouring an equal amount into a cup for each of them. "Here you take some and I'll take some."
"I'm not sure about this, Brian..." Kebin commented. "What does it do?"
"I don't know. Maybe it will make us super strong to keep up with the farm. Come on, we need all the help we can get." Brian said as he gave the cup to his brother. "Do you want to lose the farm? Me neither, so bottoms up!" Brian said as he drunk the powder. Kebin wasn't sure about it and waiter that something happened to his brother before he drinks his cup.
Brian finished drinking but nothing seemed to happen, he didn't feel stronger, faster or anything. He felt... full. His stomach started to make weird sounds like he was getting a strong stomachache. "Oh, damn!" He drops his cup and put his hands on his stomach. Maybe, you're right, Keb... I don't feel so good."
Just then Brian started to feel funny. His whole body seemed to stretch and grow longer all of sudden. "Wha- what?!! Whoa!!!" Brian tried to stay quiet as his body suddenly transformed. He was almost as tall as the door frame now. His brother, who was a little bit shorter than him now seemed pretty small to him.
Brian looked down at himself and saw his belly button peaking from underneath his now very tight t-shirt. His shorts looked more like boxer briefs that didn't cover his legs anymore.
Before Brian could get the chance to comprehend what was happening, his stomach started to growl again. Suddenly his whole body was tingling and he let out several loud burping. “Oooooh!” Brian felt uncomfortable, almost sick.
He looked down at his shoes and saw his feet starting to push through and stretch the shoes surrounding them. One by one he watched his toes burst out in front of him followed by his feet getting so big they ripped through his shoes entirely.
The growth continued up his legs as his calves and thighs grew larger ripping right though his shorts leaving the lower half of his body in just tight white briefs. "Uuuuh! Kebin help me!! I don't know what's happening to me!!" Brian shouted in pain while he tried to keep the rest of his clothes from his ripping but it was too late.
His arms were already starting to grow thick with muscles. He couldn’t help but flex his growing biceps. His back and shoulders grew so thick that his once loose fitting t-shirt didn’t stand a chance. Brian’s only piece of clothing that remained was his now tight fitting underwear.
Brian looked down at his torso and noticed that his body began to form a thick chest and lean abs to match his strong arms. He was a little freaked out when he watched some hair growing under his belly button and around his nipples. It felt itchy, and that feeling was moving through his legs, crotch, armpits and face.
Brian tried to keep some dignity in front of Kebin, so he didn't scratched his itchiness, but he touched his itchy face instead. Through his hands he could feel his face began to transform into one resembling an older version of his young self. He can feel hair between his finger, probably some stubble thickening into a proper beard. Despite that, he can notice his jaw was so firm and masculine now.
While investigating his new face. Brian didn’t realize about the growth that was starting to happen inside of his tight underwear. However, Kebin can see it. Brian’s small butt began to bulge from behind him as it grew larger and larger. Until Brian was interrupted by the sound of a loud rip from behind him.
He cupped his now bubble butt with his hands in shame and was shocked by how big it was now. "What the-?!!" Brian couldn’t believe it, his ass was huge, but his fascinated expression changed into shame when he felt some hair protruding from his ass crack.
While he was feeling ashamed of his exposed butt, Brian started to feel something really weird happening in the front. It was making him giggle quietly and then feeling super weird to the point he was moaning a little. He realized that his balls were growing until they were big enough to drop.
"Uuuuuh!" Brian moaned a little bit uncomfortable while he felt his balls swelling and stretching his tight briefs to their limit. At the same time, he can feel his dick growing longer until it's shape was clearly visible through the stretched fabric. It was too much to handle, so the right briefs finally gave up and burst out, letting his thick hairy balls hand low between his thighs and dick become fully erect and bouncing around like crazy for a moment.
Because Kebin suffered of phimosis, he can't pull his foreskin down. So, when he noticed his brother's adult cock pulling it's foreskin down by itself he can only associate it with a painful experience. However, Brian was aroused right now that he let out a pleasureful sigh instead, and started to stroke his now thick and veiny cock.
Kebin didn't understand what was his brother doing. His face seemed like he was in pain but he didn't stop. In the middle of pleasuring himself, Brian noticed that Kebinwas looking at him with a concerned expression on his face.
"Brian!! Stop it! You're scaring me!!" Kebin yelled at his brother, appalled and frightened by the 30 something year old hunk that stood before him. Brian was totally embarrassed and for a moment he tried to hide his hairy body from his little brother.
"Uhh, I’m sorry, Keb! Please don't watch me! I can't control these new urges coming from inside me." In fact, Brian couldn’t stop stroking, "I didn't expect I would become older! I just wanted to help us to keep up with the farm!"
Brian felt a pressure starting to build inside of him. "Uuuuuuh!! Oooh!!" He was moaning loudly. "Don't look, Keb!! I'm going to- Aaaaaahh!!!" He shouted while his dick released a thick white substance all over the floor and Kebin's face. "Sorry, sorry!! I’m so sorry!" Brian said really embarrassed.
Kebin didn't say a word, he just tried to clean his face and when he was done he looked at his naked grownup brother and said, "I think you're getting younger again. Look, your pee pee is getting smaller."
Brian looked down and realized that Kebin was right, however he wasn't getting younger. It was his dick just getting soft. "I don't feel I'm changing again. Look at me, I look just like dad!" Brian said trying to calm his little brother. However, he knew that he was going to do more than look like his dad now, he realized that madame Illusia's powder gave him the body to complete a fatherly role on his little brother. The question was now.
