Marcus immediately noticed that Luke wasn't just plainly disgusted. He was shaking like a jelly, losing balance and almost fainting. He was worried that something could be happening to Max's cousin, something like what happened to his former friend. "Are you ok, Luke?" Marcus asked as he tried to help him, he used his big hands to take the cum from the boy's face. Cause he didn't know what to do with it, he cleaned the white goo from his hands using his hairy belly. It was a total mess, but at least it wasn't on the boy's anymore.
Meanwhile, Luke waa hearing his stomach making very weird sounds. Uuugh! What’s happening? I feel so weird!" He groaned as his stomach started to hurt. He felt his body starting to ache all over. His jersey and cargo shorts started to feel tight. "What’s going on?! My body! What's going on with my body?!" Luke shouted nervously. Before he knew it, his body had started to grow taller. His size 8 sneakers were already feeling very tight. "You! You did the same to me! I'm turning old like you and Max, isn't it?" Luke yelled at Marcus as he felt his feet pushing against the material from inside of his shoes.
"Aaaah!!" Luke screamed as he felt his getting so small as they tried to contain his growing feet. "Stop it! Pleassssee!! I don't wanna be an adult! Not yet!! I'm not ready for it!!" Suddenly Luke’s top half of his feet bursted through his small sneakers. His toes were now long and large, but they didn't stop there because his feet continued to grow larger which caused his shoes to become demolished by his new and wide size 15 feet. His legs started to get longer and longer causing him to grow to a new height of 6'4. His arms grew longer as well. He still had a skinny build but his clothes were extremely tight on his now long body. "Oh my gosh! Look at my feet!! They're freaking huge!!"
"Please, Luke. You need to calm down." Marcus said as he gazed upon his the boy's new body. "You're being too loud! Someone else could hear you and we'll be in bigger problems." "How do you expect me to be quiet if I've grown two times my size right now?!" Luke said in a now mature, scared and nervous voice. "Oh! Ooooooh! It that weird feeling again!!" Luke groaned as he rubbed his now long and lanky arms.
He felt them inflate with muscle, forming large biceps on each arm. His jersey began to tear a bit as his back and chest widened with muscle. His exposed stomach began to tense as it formed a thick set of abs. Luke's jersey ripped open from the muscular pecs that were forming on his mature chest. At the same time, his legs began to feel weird as they expanded with thick muscle. His once baggy cargo shorts were now very tight from his overgrown muscular thighs. Then, Luke suddenly felt itchy all over. He and Marcus looked down to see that hair started sprouting all over Luke's body.
"Ugh! Make it stop! Please!! It feels like ants eating my skin!!" Luke pleaded as he desperately scratched his neck, his armpits and around his crotch. He can feel tiny coarse hairs poking out of those places while he rapidly matured into a man. "Uuugh! Help me, Marcus!! I don’t wanna be big! My clothes feel so tight but I don't wanna be nake!!" Luke cried out. Marcus can't do anything but just gaze upon Luke's growing body. He knew that the only one who can help them was Jeanie, but she wasn't around.
Meanwhile, Luke was groaning in pain as he reached down for his tight cargo shorts. "Uh!! Uh!! Oh no! It's already happeniiiing!!" He began to moan as he felt his dick trying to burst through the fabric, it was too tight that it was as painful as it was arousing. His balls were inflating and showed no signs of stopping. His dick continued to push and push against his tight shorts but they weren't giving in yet. "Aaaahh! It's so tight!! Aaaahh!!" The strong fabric was so painful around Luke's growing package.
"UGH!! I can't hold it anymore!!" Finally, he had enough. He used his now grown-up strength to rip his tight shorts open. Marcus watched how Luke's large and throbbing schlong popped right out from his now skin-tight shorts. His thick balls were also free and Marcus can see them disturbingly hanging low full of pubic hair. "Aaaah That's better." A sigh of relief came from Luke as his dick was now free from the restraints of his tight shorts.
Luke's transformation was now complete. He was now has the body of a large 6'8 jock in his late twenties. He looked strong and virile but he seemed very unpleased with the result. "Are you ok?! Luke how do you feel?" Marcus asked as he noticed that Luke wasn't moving since he tore off his shorts. Dumbfounded and exhausted, Luke said in a new deeper voice, "A little funny but the pain is gone." He said as his dick was throbbing and begging for attention. Marcus can see Luke wanted to touch it but he was containing himself.
Marcus knew how Luke was feeling and that he won't be helpful until he released his first load. So, trying to push him to do it, Marcus took Luke's bigger and calloused hands and guided them to Luke's fat salami. "What are you do-UGGH!!!" Luke tried to protest but Marcus had started to stroke Luke's thick and throbbing cock. "HEY!! UGH!!!! AHHH!!" Luke's eyes rolled back from the pleasure. After a few seconds he didn't need Marcus' help. He was jacking off by his own.
"AH!!! UH!!!" Luke could felt a pressure building from inside of him with every stroke that he did on his large dick. "UUUUUUUH!!" Suddenly he released a thick a heavy dose of sperm all over himself and Marcus. You could say it was a kind of revenge of what Marcus had done to Luke before.
Out of breath and weak, Luke looked at Marcus, he was now taller than the man in front of him! "How are you feeling now?" Marcus asked cleaning off his body looking up at Luke. "Weird. I can't believe now I'm in the same situation than you and Max." Luke said as he looked down at the body he got after his massive growth spurt. "Luckily for me, I've found several adult size clothes. So, we won't be naked for so long." He pointed at the pile of clothes on the floor while Marcus took them. "It's kind of bizarre..."
"What?" Marcus asked as he kneeled. "As a kid, my penis and testicles are not that important, just some sensitive lumps to cover. But now..." Luke said as he began to sway his dick. It was so big and heavy that it makes some slap sounds when it hit Luke's muscular thighs. "It feels like I'm having a third leg or so. I don't know if it would get comfortable with some time, but for now it feels totally foreign to the rest of me."
After wearing some briefs, pants and tank tops. Marcus and Luke were ready to look for Max. But... Where to start? The forest was so vast and full of wildlife and they were... Umm... Barefoot and still learning to walk with those obscene bulges between their legs. "Where are you, Jeanie?" Marcus thought as they came out of their cabin through the window.
