She decides to take 12 since she loves things in dozens.
After she finishes taking the pills she begins to feel a warmth in her panties. When she reaches down to grab her crotch she feels a large lump between her legs.
"What the hell? What's happening to me?!" She squeals as she looks down to see a massive bulge in her pink satin dress.
As the penis snakes it's ways down, she runs her hands across it through the fabric of her dress. As she becomes enticed by the hidden pleasures of it, she begins to feel overcome by a lascivious urge welling inside her.
Kara grinned as she realized what has become of her. Part of her wanted scream, and yell, and through a hissy fit like no other, but a stronger drive had taken hold now. You see Kara had always been on the small side when it came to her breasts. Being an A cup was something most considered to be her only flaw. She has beautiful flowing blonde locks, smooth supple legs, a generous ass that made anyone with an attraction to women give a second glance, and a smile that could have sent Troy and Greece into war.
But for Kara it wasn't enough. Many of the other girls were jealous of her flawless good looks. They began flaunting their larger cup sizes to make her feel less feminine and enervate her self-esteem. She had always been a nice girl, and she even joined a soroity with many of the girls who teased her before. But nothing had truly changed, despite her attempts to bury the hatchet, many of the girls still teased her about her breasts.
Now all of that is going to change. She put a hand on her hip and began to strut back to the soroity house, confidently putting the bulge in her dress on full display for the world to see. She was more well hung than any guy she had ever seen before. She felt more feminine than ever before, and all it took was growing a massive 12 inch dick (8" when flaccid). She loved the way her panties pressed against her schlong. Most would call it uncomfortable but she was enamored with the way that it drew her attention back to her new cock and large balls with every step.
"It's time to knock the rest of the girls down a few pegs." She then began silently racking her brain for ways to get back at the girls who bullied her.
