Ok, fine, Joanna shouldn't have spiked Cassandra's food with Expandi-grow, but the short, petite redhead had been complaining non stop for the past couple of days about her flat body. Every waking moment she would hear how Cassandra lacked an ass, how she lacked tits, but did Cassandra ever think to consider that maybe Joanna didn't want to hear it?
So, what was she supposed to do? Of course, she should have confronted Cassandra about it and had a serious adult conversation. But she was irritated beyond belief, and so, when they had their next movie night, she made sure to buy some Expandi-grow from one of her contacts and dumped the entire little baggie into the chow mein they were having.
When Cassandra took her huge plate of chow mein, Joanna was having trouble keeping her laughter inside. She would have to stop her after the first bite, but it was still fun to imagine what would happen if she ate the whole plate. Her giggly mood went down the drain when she walked into the living room to find that Cassandra had indeed eaten the entire plate of chow mein and Joanna's plate as well.
It wasn't long after, that Cassandra's tits began to expand. At first, Joanna decided to play off what was about to happen as something supernatural, or something medical, anything to take the blame off of herself. But when the tight shirt that Cassandra always wore began to swell lightly, she began doubting how much she could keep her involvement a secret.
The redhead didn't seem to notice at first, her green eyes glued to the screen. She didn't seem to notice when her shirt had begun to ride up, exposing her smooth flat stomach. It wasn't until her bra had begun to dig uncomfortably into her back and shoulders that she finally took notice.
As would be the reaction of any sane person, Cassandra freaked out. Her eyes darted between her slowly swelling breasts, which had gone from an A cup and now to a B cup, to Joanna. The girl culpable for all of this simply stared, her face showing no surprise at what was happening.
"What the fuck is happening to me?!" Cassandra asked, distressed.
Joanna's resolve lasted an entire five seconds.
"I spiked our food with Expandi-Grow," began Joanna, her eyes glued to Cassandra's growing breasts. "You weren't supposed to eat it all, and not that fast. I was going to stop you after a bite, but you ate it all!" She explained, afraid of Cassandra's reaction.
To Joanna's surprise, however, Cassandra began laughing. She laughed hysterically, pointing at Joanna's face.
"Jesus Christ, your face." She howled, unconcerned with her now D cup breasts. Cassandra reached to her back and unclasped her bra. She took off her shirt as well, exposing herself to Joanna.
"I knew that you spiked our food, that's why I ate it. Now I can grow some real fucking tits." She growled.
Anger replaced all concern within Joanna. And before either girl knew it, Joannas was on top of Cassandra, wrestling with her playfully.
