Derek had an incredible blast with Sean. It was amazing, seeing how a cute girl like Sarah came over to his house and how she quickly transformed and grew into a young muscle guy like Sean. Not only did she become a guy, but he was tall and muscular, all thanks to the Chronivac which Derek’s friend Jeff had set up for him earlier that day. Jeff had set it up that any girl, who was within 10 feet of Derek for any given period, would age to 18 years old and would become very aroused and muscular. Derek’s first “victim” was Sarah, who left his house as the hunky Sean, after spending the night.
So, Derek met up with Jeff and told him about his experience. Jeff and Derek shared the apartment, so it was easy. Jeff owned a Chronivac device in his room, which was connected to his laptop.
“Dude! It’s amazing! I mean, she quickly regressed back to 18 and changed into a college dude with big muscles! But…” Derek sighed.
“What? What’s wrong?” Jeff wondered.
“Sean was nice, but he was kinda… Lean. He wasn’t very big!” Derek sighed.
“You mean, you want the girls to gain even more muscle, after they transform into guys?” Jeff reasoned.
“Yeah! Like BIG bodybuilders! Huge young muscle men! Like, they had spent years in the gym!” Derek smiled. “I wanna be surrounded by muscle. That’s why I want to have a hunky boyfriend and not a skinny girlfriend! I want a partner with huge quads, thick abs and big biceps!”
“Easy!” Jeff smiled as I changed a few settings on the Chronivac. “I made it so the girls will still change into young guys, but after they change, they’ll gain a LOT of muscle!”
“Ohhh… Nice!” Derek nodded. “I can’t wait to invite another chick over and to see what kind of dude she changes into!”
Derek took his cell phone and walked into his room. He glanced over his contact list and looked over all the names and numbers. He finally found someone he could call, just to see if the Chronivac worked. He spotted the name of a young lady named Jessica, who took some of the same college classes as him.
He called her up and invited her over to watch a movie at his apartment, just for fun. He would order a pizza and he would get a movie online to stream. All she needed to do was show up.
“Hey, Derek! How nice of you to call me! Sure, I’ll come over and hang out with you! Very cool!” she said. A few hours lady, Jessica came over after she had her workout at the local gym down the street. Jessica was very dedicated to working out, and she loved to show off her short, slim, firm and toned physique. She was 5 feet tall and she had thick thighs and big calves. She had a six-pack and short, slender arms. She was short and muscular. She had long black hair, tied together in a ponytail in the back. Just the way Derek liked it.
“Hi Derek!” she smiled as she walked in, still wearing her gym clothes and sneakers.
Derek led her to the coffee table, where he set down the pizza box and two cans of fruit juice. As he sat down on the couch right next to her in order to have a nice chat, he noticed how Jessica started to change.
Over a period of an hour, Jessica experienced a very slow, gradual and smooth transformation as her body became more masculine. She grew taller and she gained more muscle. She sat on the couch, watching TV and eating pizza. While she sat there, her legs slowly grew longer and more muscular, as muscle was added to her quads and calves. She rested her ankles on the footstool, but she had to constantly adjust the placement of the footstool just because her legs kept on growing longer.
Jessica didn’t notice anything during the first hour, but Derek started to see the changes. He spotted her longer legs and the added muscle. He also noted how her arms started to fill out with bigger, bulging biceps and triceps. Her gym shirt started to feel very tight in her arms.
Next, her breasts began to flatten. However, her chest new grew big, round, large orbs of pec-muscle. Big boobs were suddenly replaced with large, round pecs. Her torso widened and her flat stomach now began to fill up with well-defined abdominal muscles. All this muscle strained her gym shirt even more!
Derek just smiled as the changes became more obvious. Jessica was getting more uncomfortable, and she asked if she could take off her gym clothes. Derek just nodded, and she removed her shirt and she just put on her shorts.
As she stood up to get her clothes, Derek noticed how she had gained almost a foot in height. She was also regressing from age 24 down to age 18 and turning back to an 18-year-old boy! Her face was changing, and she started to gain more hair in her armpits, on her chest, on her arms, her legs, and on her face.
“Are you alright?” Derek asked her, as she sat there, feeling her face and her arms with her hands.
“Uhh… I’m feeling kinda… hairy all over…” she sighed.
Finally, she got up and walked to the bathroom, only to come back, a minute later.
“Holy shit! I’m a GUY! I’m not even a chick anymore! I’m a DUDE!” she – or HE gasped.
“Grab a seat, Jesse…” Derek smiled, as he patted on the couch next to him.
Jesse had accepted his new name as he carefully sat down on the couch. After all, he was just hanging out with Derek… It was just two young college guys, enjoying a pizza together, right?
But Jesse’s growth wasn’t over. His muscles kept on growing. Jesse was about 6 feet tall now, but he kept on packing more muscle on to his frame.
Jesse was overcome by an intense tingling sensation in ALL his muscles, throughout his entire body, and all at once! Every muscle tensed up as everything started to grow more and more and MORE!
“Hey! What’s happening? I’m growing! I’m getting more…. UHHHH!” Jesse groaned loudly as his muscular growth accelerated rapidly while Derek looked on with a wide grin on his face. What was happening to Jesse’s body was truly incredible!
Jesse’s cock and balls grew exponentially, inflating until his balls touched the ground as two large basketballs, tied together by flesh and bones. His cock grew into a mighty manhood, which was a big, long, 18-inch python. It was long and inhumane, to say the least! But that was the least of his worries.
Jesse’s muscles continued to inflate, and they became absolutely stunning in size. They became so massive, Jesse’s body had to change in width as his spinal cord widened drastically. Large mounds of muscle inflated on his legs, his arms, his shoulders and on his back, making him look like a large, walking inflatable balloon. He waddled around with massive mounds of muscle. His entire body grew to ten feet wide. His arms were super-thick and wide, with so much muscle on them, that he could barely even move. His legs were bigger than the pillars on any major building, filled with huge pilons of thick, solid muscle. His quads were over three feet wide. His shoulders, together with his pecs and his lats, were just incredible, flanked by so many large mounds of muscle sticking out, that he resembled a walking wall of muscle. Jesse suddenly gained over 700 pounds of rock-solid muscle, becoming a walking, talking and living human muscle block. It was a miracle he could even walk.
For Derek, this was his dream come true. He had wanted a girl to change into a muscle man, and he got it. Jessica changed into a muscle guy with over 500 pounds of muscle added to his frame. He was absolutely humongous! There were no clothes big enough to cover this enormous, expansive body. But Derek didn’t care. He was going to spend the whole evening with this huge muscle creature, rubbing, hugging and cuddling him. And, there was this enormous cock and balls, of course. Derek had enough to work with. He had a whole night and another day to have fun with Jesse, the muscle giant.
