These barely fit! (Patreon)

Jackie stepped into the bathroom after her cramps returned. It was the worst pain she'd felt in ages, but she knew that her body was changing again. And once she made her way to the mirror, she couldn't keep her eyes off her large, natural breasts. She was pleased to see that the potion had transferred even more of Sabrina's attributes to her body. 

As a novice potion brewer, Jackie was worried that using the popular girl's strand of hair in her potion would lead to problems. There was a list of potential problems with the DNA manipulating potion, and thankfully, none of them seemed to be happening. As she squeezed her brand-new breasts, she felt a rush of heat flowing through her. It felt so strange - she didn't remember being this horny in the past.

“These are way bigger than Sabrina’s breasts,” she whispered. “Wow … I’m going to need a new bra. These can barely fit in here.” Years of being jealous over Sabrina’s perfect body made her decide to do something completely harmless to her former high school friend. Jackie had always felt like a boring ginger, so having a body that looked physically sexier was something she was interested in once she realized that she could use another person’s hair to splice one’s DNA.

But then she felt the pain return, and she knew that she was starting to change again. "This soon? These literally just grew…" As she walked, she couldn't help but notice how different her gait was now. Her hips were swaying back and forth more, and she could feel her breasts bouncing more heavily with every step. She looked down at her waist and was shocked to see that her hips were widening. 

Sure, she felt sexy, but she was starting to worry about just how far the potion would alter her body. She only wanted certain features, and now, Jackie was starting to change more than she wanted. She went back into her bedroom and grabbed at her throbbing tummy as she groaned. Wincing, she looked at the nearby potion book and let out a surprised moan.

Her eyes fell upon the ingredients list, and she realized that she had messed up. The concoction required Sabrina's hair, but it also needed significantly less water and blood that Jackie had actually used. "I used too much," she realized. "Oh no … this isn't good. This isn't good at all."

A wave of heat ran through her, and she felt her hair transforming. Her long, luscious red hair became wavy and brown. Her voice changed, and she felt her mind going blank. Slowly but surely, she found that her mind was slowly growing dumber with every passing second. The potion book no longer made sense to her, no matter how long she stared at the words as she realized that she'd been turned into a bimbo version of Sabrina. She had become physically stunning, but at what cost?

She wanted to cry, but the transformation had taken away even that part of her. Now, all she could think about was how hot and bothered she was. Her pussy was dripping wet, and her nipples were hard as rocks. Her body was so sensitive that even the slightest touch made her moan and groan in pleasure, and in a way, she actually liked how she was now. "Maybe this won't be so bad…"
