Vlad.

Krista was watching her boyfriend’s wrestling team for their college. They were in the top division, and were in the top three of that division. The team was about to enter the division tourney which would decide the winners for the game. “You were great” she said hugging Jeremy’s sweating body.
“Thanks” he said smiling at his girlfriend. “But Cornwall will kill us...unless we get something together” he said to Krista.
“You always think of something” Krista said as the two of them went out to the car. “Where we going tonight?” she asked Jeremy.
“We are gonna go somewhere different” he said as they got to his car.
“What kind of different?” Krista asked. “Like instead of vodka, we are gonna drink tequila?” she asked Jeremy thinking they were going to
an afterparty.
“Guess it isn't that simple” he said as they drove away from the school.
“I’m so excited...just to start this weekend” Krista said to Jeremy as she lit up a cigarette in the car. “I just think if you guys put your mind too this tournament you'll win” she said smiling at Jeremy.
“I guess” he said slightly annoyed that Krista was smoking in his car. They then went to the outskirts of their city to a factory that was sometimes used to throw giant parties.
“Holy shit...we are throwing a giant party?” Krista said excited.
“Not exactly” Jeremy said as he parked the car around several other ones. “Follow me” he said as the two of them went into the entrance of
the factory.
“Wow” Krista said as she looked around to see the place had mats, and everything. “Is this your secret practice camp?” she asked Jeremy. “Yeah it is” he said to Krista as he was looking around the factory.
“Babe...why do you look so paranoid?” Krista asked Jeremy.
“I guess...it’s time” he said before whistling. Several of the bigger guys came out of the dark, and grabbed Krista by her arms. “Take her,
and get her ready” Jeremy said before walking away.
“Jeremy is this some sort of prank?” Krista asked him as the two brutes brought her too a different dimly lit room.
“Put this on” one of the guys said tossing her a wrestling singlet.
“Really?” she asked them.
“Yes...put that shit on” they said as they shut the door. Krista was horrified, she had no idea what prank Jeremy was planning, but she was
scared for her life. “You have 15 seconds” one of the brutes outside said.
“Shit” Krista said as she had no choice, but to put on the tight, yet still loose singlet. She opened the door wearing nothing but her socks, and the singlet. She was taken back to the mats in the middle of the factory. She then saw Jeremy with one of the science nerds from her grade. 
The brutes then threw Krista onto the ground. “Jeremy? This is just a joke right. Cause I won’t say anything if it is. I just want to go home...or maybe a party” she begged to Jeremy who gave an evil grin.
“Krista...don’t worry you'll be okay soon” Jeremy said as the nerd smirked. Krista glared at the nerd knowing that she used to bully him. “Alvin” Jeremy said as he gave Jeremy a syringe. “Now you'll go from a bitch, to someone that'll contribute to this school” Jeremy said.
“Jeremy...I’m your girlfriend” Krista said as he was about to inject her.
“Well...I’ve been secretly fucking Erin Lamb, and she’s pretty cool. Think I’ll manage without you” Jeremy said as Krista yelped as he injected the fluid into her neck. Krista held her neck as she looked up in horror at Jeremy. “Now we should have someone equal to takedown Eagle’s Howard” Jeremy said as he smiled to his other team members. As they watched Krista fell down to her knees.
Krista raised her head up as the injection site began to reddened as the veins began to pulsate. Krista’s limbs started to get longer as Krista squealed as she extended her legs to see them growing longer. Her arms followed as she watched her hands growing to their new size. Her fingers thickened as Krista watched as black hairs grew on her hands. “No” she said in a gruff voice as the black hairs started growing down her arms. As the hair traveled up her arms, her forearms swelled with muscle as her longer arms swelled with muscle.
The guys watched in complete fascination as the black hair went around her broadening shoulders, as her chest receded, and muscle swelled on her now muscular hairy chest. The black hair grew onto her hardening stomach as the upper part of the singlet fit tightly on Krista’s masculine torso. The guys then watched as her legs thickened with
muscle as the black hair grew all over Krista’s legs. 
Krista was hysterically crying as the guys speaking was becoming more gibberish too her. Her feet then swelled as they tore threw her socks. Her toes grew thicker as the black hair grew on her feet. Her thighs thickened as her butt swelled with muscle fitting the singlet perfectly. Krista’s then felt another sensation as she cried even harder as a large bulge grew. The guys laughed in humor as they saw a once beautiful girl turning into some sort of hairy ape- man.
Krista’s hair started to shortened, and thin as it turned jet black. Her neck thickened as her features began to shift. A deep voice left Krista’s mouth as it said something foreign. Krista’s deepening voice tried to communicate with the guys, but she realized that she was speaking another language, Russian to be exact. Krista’s mind then started to burn as the new hormones, and the chemicals started to alter Krista’s brain. Her features began to harden as her chin squared, and her nose grew larger, and more pointed. Her eyebrows thickened, and turned black. Krista let out a deep bellow as a stream of cum started seeping through the singlet.
Krista’s mind was being morphed into someone else. A simpler mind was erasing the hectic mind of Krista. A life of training in a Russian village was overtaking Krista’s. The new man Vlad started screaming as the stream of cum got thicker as everything that was Krista was shot out of Vlad’s dick. “Welcome to the team” Jeremy said helping Vlad up.
Vlad was confused, but was happy he was with his new team. “Thank...you” he said in a very slow thickly Russian accent.
“We will teach you more” Jeremy said as he let his new team member sleep over his house. Jeremy laughed as he would rather have a new friend in Vlad, then continue dating Krista.
The next morning the team went into practice seeing their new hairy team member Vlad. A Russian exchange student Vlad, who was going to be a top competitor against one of their rival teams. Now they just needed to match several more guys.
