Three hours after changing John with the Chronivac, Barbie decided to check in on him and his friends. Barbie had hoped that one or more of them would have treated John like shit, just like he did to her, and then he would finally understand how much of a jerk he was. It would be a bonus if all of his friends learned a lesson about treating their friend, now a woman, poorly.
Barbie found an option in the Chronivac to let her spy on John to see how things were going. A screen popped up showing the group, live and in ultra HD with full audio, no less.
Barbie was shocked to see that John's three friends were busy fucking John's brains out. It looked like they were in Mark's basement. John was currently on her hands and knees with Pedro ramming his cock down her throat, Mark plowing her ass and Nick furiously lapping away at her dripping pussy. Nick was positioned so that John was able to wrap her slender hand around his cock, which she was frantically jerking off. John was moaning loadout around Pedro's cock. She was mercilessly twisting her nipples with her free hand.
Barbie could easily tell that John had taken several loads in or on all parts of her body. There was cum everywhere. It was in her hair; smeared on her face, hands, tits, back and ass; she could even see it dripping from her ass AND her pussy, which was shocking considering Nick was basically lapping up his own, or someone else's, load. Men were such fucking hippocrites.
She could tell that all of them were having a grand old time. Mark and Pedro were casually chatting and high fiving each other frequently, while Nick had a devilish grin on his face between licks. Even John, now Joan, seemed to be intensely enjoying her new situation.
Barbie's blood was boiling. This was supposed to be a punishment, but now all of them were having a fucking blast and orgasming over and over. She couldn't let this stand! They all had to be punished.
Barbie brought up the Chronivac command screen and furiously started typing in commands. She let the video and audio up, which continued to infuriate and inspire her.
After about ten minutes of typing and revising, Barbie suddenly stood up and glared at the orgy one last time. She hit the enter key on her keyboard and vanished in a flash of light.
Just as quickly as she vanished, she appeared in front of the guys (and girl). They all appeared to be shocked to see her but, for some reason, continued on with their fuck session as if nothing had happened.
They all appeared as if they wanted to say something, but they were unable to make a single peep.
"You fucking assholes," Barbie said as she made eye contact with each of them, "I tried to teach you all a lesson but instead you just start fucking John all night long?"
Each of them continued to fuck and suck John.
The only noises in the room were the wet smacking sounds of a fuck fest along with John's aroused moaning.
"Well guess what, fuck heads," Barbie said angrily, "you're definitely not going to be happy with what comes next."
Everyone watched in awe as Barbie's clothes vanished from her body. As she stood there naked, a huge grin splayed across her face, they could see her body start to vibrate. Suddenly her body began to rapidly change. It was like watching a naked Bruce Banner turn into the Hulk, except it was obviously a woman turning into a man.
Her hair shrank into her head until nothing was left but a short, trendy fade. Her arms and chest exploded with muscle, her tits flattening and her nipples shrinking and pointing downwards as her pecs inflated in size. Her stomach rippled as an 8pack of abs etched into her stomach. Her legs exploded in size, resembling tree trunks, each muscle clearly defined and covered in bulging veins. Her hands and feet grew to massive size. Dark hair sprouted across her legs, arms and torso. A thick beard covered her face as her jaw sharpened, a large adams apple pushed out from her neck, her nose flattened and grew wider, her brow became more prominent.
For a brief moment, Barbie stood in front of them as a massive, hairy hulk of a man that would put any body builder to shame. All that was missing was a cock. Barbie saw that everyone's eyes were locked onto her groin, and smiled as she felt a pressure building in her dainty, lady pussy.
A massive cock and balls burst out of her crotch. Her shaft was at least a foot long and as thick as a beer can, but still completely soft. Her balls were the size of oranges and hung halfway to her knees. They looked swollen and full, and they were. Barbie had instructed the Chronivac to give her the ability to shoot massive loads as frequently as she desired.
Barbie took several deep breaths, her massive chest heaving. She ran her hands up her torso, running her fingers along her huge muscles and through her body hair. She stroked her beard with one hand and ran her other hand through her short hair.
She chuckled as she reached down with both hands and started to rub her massive cock to life. It took less than a minute for her cock to become fully erect. It was massive, maybe even up to 15 inches in length with a huge, angry knob of a head.
She grunted in pleasure as her first massive load erupted out of her cock, flying across the room and splattering loudly against all of the guys that were watching her transformation. Shot after shot erupted out Barbie's huge cock until all of the guys (and John) were drenched in Barbie's jizz. They continued to fuck each other without reacting, the slippery cum making all of their movements sound wetter and louder.
Barbie smiled broadly and laughed as she saw the fun rapidly absorb into their skin.
"Now it's time for the real fun to start, boys" as they all felt their bodies begin to change.
