Jason lays back in the chair, massaging his fat member, feeling the new sensations that he had only learned his new body could feel, looking at his 'little' brother now, making him even hornier, knowing he had power over his brother.
"So bro, now I'm the man, you have to do everything I tell you to!" Jason said with a grin on his face, the idea of having control made his hardness twitch, begging for attention. Soon, the male hormones took over his animalistic sex drive and he furiously pounded away at his new cock, laying back on the couch.
Matt sits on the floor indian style, watching in half shock and fear, amazed at the scene unfolding before him. He was supposed to be the big brother. The one with the control, the one that was looked up to. All he could think about now was the big dickie in front of him. He wanted to be the big boy. And it wasnt fair. He looked on as his little brother jacked his hard cock with his eyes closed.
Jason was awash in WILD feelings of invincibility, as the hormones washed over his 11 year old mind in a 19 year old body. His eyes shut tight, he felt his orgasm approaching, the strongest one yet that he experienced. Pretty soon, his balls drew up and he fires 8 hard shots of cum all over his chest and face, the orgasm so strong that he blacks out, eyes slightly open and crossed, tongue stuck out. The feelings were too much for his 11 year old mind and it checked out.
Matt snapped out of his shock as he heard the big splats of cum splatter all over his brother. Looking over, he was in a tizzy. One side of him wanted his big dickie back. The other side felt disgust at having to eat his brothers cum to grow up again. Matt saw his brother passed out, so he decided to go ahead and do it if he ever wanted control. Matt knew Jason was out of control, 11 year olds can't handle the emotions and sexual feelings of being a teen, so Matt wanted to do him a favor.
Matt walks over to his unconscious brother and starts to suck the cum off his brothers face, working his way down. Matt feels his body get hot as the cum starts to catalyze inside his body as soon as he smurches the cum off Jason. Matt moves lower and sucks the cum off his brothers hairy stomach, seeing the hair thin a little bit, his skin now burning as the cum worked its magic. Matt looked down towards the treasure trail and keeps sucking and licking up the nasty semen, and feels his bones restructuring and reorganzing themselves.
Soon, before Matt reaches Jasons now 16 year old cock, he gets an idea and runs to the bathroom. He looks at himself and finds that hes around 12 years old, his little cock with a sprinking of hair and around 4 inches long. Matt runs to his dads nightstand, and grabs the pair of handcuffs that his dad keeps in the drawer, next to his Police mans badge. Matt stuffs the key to the cuffs in his sock and runs back downstairs and finds Jason still passed out. Working quickly, Matt cuffs Jasons hands around the arm of the couch and goes back to work on the remaining cum. Sucking all of it Matt started to realize something was changing. When he started, he was disgusted with the taste and idea of what he was doing. Now, with every bit that he swallowed, he became hungry for more. Matt felt something odd happening the same time he was growing. He felt something enveloping his dick. Looking down, eating all the semen had caused him to grow a foreskin. Something that he didnt have before. Looking at Jason, who had diminished most of the body hair that he had grown, had also developed a foreskin. Matt grinned in delight, feeling new gay feelings wash over him as he aged to 13. Somehow the semen was aging him slower, but adding things to his dick. It had not been so kind to Jason, who looked to be barely eleven now.
Matt stood up and tightened the cuffs a few more clicks, not wanting Jason to wake up and squirm out. Matt moved down and ate the leftover cum from around Jasons now hairless dick. Matt was still hungry for more, so he pulled his little brothers new foreskin back and started to eat the last remanants of semen from his dick. SOon, Matt felt himself bobbing up and down on Jasons dickie, and Jason started to writhe on the couch, moaning a little, the feelings washing over him again.
"Ooohhhh" JAson cooed gently. Matt heard the high pitched moans of his little brother. MAtt was a little upset that he wasn't aging from his 13 years, but he was clearly bigger and more mature than Jason.
Jason, who was coming to as the sexual feelings started stimulating him. Thinking to himself, I never want to be a kid again. Jason felt something holding his hands above his head, cold steel, then he felt something warm and wet on his cock. His fat man cock. Jasons eyes flew open and there was his worst fear. He was a kid again. Slipping from 11 and getting younger. And there was Matt, between his legs, older than he is now.
"NOOOO!!! I dont want to be little! Give me back my big weenie!!" Matt whined like the kid he was becoming. Pretty soon those complaints washed away as Jason started bobbing up and down fast on his brothers newly uncut cock.
"Oh Matty, it feels nicceeeee" Jason hissed, not sure what he wanted to do, get his rocks off or keep his age.
"Untie me!" Jason demanded.
Matt pulls off his little brother and smiles.
"NO way little bro, I was never mean to you when you were littler. In fact, I treated you pretty good. All you did to me was bully me. So im teaching you a lesson."
Jason looks down between his legs. "Why is my dickie different?" MAtt pulls his foreskin down, causing his brother to shudder in pleasure.
"You mean this? We grew foreskins, they were cut off when we were born, but we got em back. Must be a side effect." Matt explained as he rubbed his thumb over the sensitive head of his brother.
Matt was so horny that he started to suck faster on Jason, bringing him to an explosive climax. Jasons screamed at the top of his lungs as his orgasm pushes him to 9. Matt slows down and pulls off his little brothers dicklet, smiling at his own work.
Matt looks down at himself and sees that he has fair skin, freckles and a few sparse hairs around his abdomen, and a long foreksin, that covers his cock even when hard. Matt starts to pull his foreskin back and shivers, pulling fast on his dick, it wasnt long before he exploded all over himself. Matt greedily ate up all his cum, expecting to get some more growth. After a few mins, his cock grew another half inch to four and a half and the foreskin fit a little more snug.
By that time, Jason had waken again. Not only was he younger than MAtt, this time he was only NINE! Jason whined at the situation.
"noooooo!" he whined. "Give me back my big dickie!!!" Jason walks over and smiles.
"Not anymore. I'm the big brother again! ANd I'm gonna be nice to you and treat you like a big brother should! I'm gonna watch out for you and spend time with you!" Matt leans in and kisses his brother on the lips, pulls back and sees that his brother has developed the same fair skin, freckles and red hair as he did. Matt smiles.
"And make you feel nice too!" Matt reaches down and starts to play with his brothers hairless dick.
"You like it when big brother plays with your weenie?"
