McKenzie struggles through the school day.

Things were definitely getting worse.

McKenzie sat on the toilet, gaping at her crotch. Her clit was even bigger now than it had been this morning. The organ jutted nearly an inch and a half from her crotch, it’s color deepening from pink to an angry purple. It ached and itched and seemed to pulsate with McKenzie’s rapidly increasing heart rate.

To make matters worse, her entire lower body hurt like a motherfucker. It almost felt like someone was taking one of those stick blenders to her insides.

This had to be some kind of infection. That seemed like the only reasonable answer to what was happening to her. It sucked too, because that meant McKenna had to go to the nurse and she hated doing so. The school nurse was a total uptight bitch.

There was a knock on the stall and a soft, sweet voice that said, “McKenzie, are you almost ready?”

It was the voice of Jessie Gomez, McKenzie’s best friend. The two girls had gym class together and McKenzie had been in the process of changing into her uniform. That had been five minutes ago.

“I’ll meet you out there,” McKenzie muttered.

“Coach Hastings is getting mad, McKenzie,” Jessie replied.

“Ugh, fine. Whatever.”

McKenzie felt more irritable by the second. She quickly changed not her gym uniform and slammed open the stall door. There, standing before her, was Jessie in all her glory.

McKenzie’s best friend was a gorgeous girl with a sweet, bright-eyed face and a curvy bombshell body. Even in the school gym clothes (an oversized t-shirt and shorts), Jessie seemed to stretch the fabric with her magnificent proportions.

McKenzie had always known her best friend was hot in a clinical way, but now, for the first time, she really understood it. Jessie was a total fucking babe!

McKenzie felt a painful throb in her nether regions and swore her clit grew a little bigger.- - - - - -

Gym was a mistake. For one thing, McKenzie’s abdomen was hurting so much now that she spent every other second wincing under her breath. She could hardly stand up straight, let alone run. However, this was hardly the worst part.

For eighteen years of McKenzie’s life, she had been straight as a board. All of that went out the window today, apparently.

For the first few minutes, McKenzie valiantly tried to avert her gaze from her best friend’s perfect ass and bulging tits. Unfortunately, this proved to be a futile endeavor. Especially since the pain in McKenzie’s abdomen made it nearly impossible to focus on anything.

Even worse was the fact that Jessie was hardly the only hottie in the gym class. There was Helen Yu, who had what might be best described as the tightest ass in history. Then there was Isabella Jenkins who had lips begging to be kissed. Then there was Annie Myers. It was with Annie the everything came to a head.

Up until recently, Annie Myers has been a bespectacled, pimply, flat chested nerd. She had long, messy brown hair that always looked unkempt and overgrown and a little greasy. She was a sweet girl, but all-in-all fairly unlucky with the genetic lottery — that is until a little less than a month ago.

Finally in her senior year, puberty had decided to come visit. Really it visited, through a rave, smashed all the windows, and set the house on fire. Annie’s boyish, flat chested had erupted into a pair of luscious, titties worthy of a playboy centerfold. Her butt had grown plump and round and mouth watering. Even her acne had cleared up, leaving a cute, if somewhat bewildered looking face. Annie still had her greasy, overgrown hair and thick, coke bottle glasses, a remnant shell of her old nerdy self that could barely contain the goddess within.

Because Annie had blossomed so quickly, none of her clothes fit. McKenzie actually felt sorry for the girl, who was **** to play gym basketball in a t-shirt that couldn’t even cover her bellybutton and seemed to suction to her new breasts.

However, pity was the last thing on McKenzie’s mind as she collided with Annie on the basketball court. For a second, the world spun and McKenzie was **** to reach out to stabilize herself. It was then that her right hand sank into something soft and plump and oh-so-pleasant. McKenzie, knew what she was touching the second she made contact, but some alien urge compelled her to linger for far too long.

As McKenzie touched Annie’s breast, she felt an unholy rush between her legs, followed by a gut wrenching pain in her abdomen and clit. She swore she could actually feel her clit getting bigger with each passing second she touched poor Annie.

Eventually, after about five seconds, McKenzie rocketed back to her senses and found herself staring into the mortified eyes of Annie Myers. It occurred to McKenzie that this was quite possibly the first time someone else had touched the girl’s breasts.

Everyone was watching the two of them. McKenzie recoiled and began to babble incoherently as she backed away from the stunned class. Finally, she blurted our the word “nurse!” And ran off.

McKenzie hoped to God the stuck up school nurse might have an answer for this bullshit because she certainly didn’t.
