"Bree..." Lynn, not sure what came over her, slides closer to Bree. Lynn knew that her friend shouldn't have male equipment, but there it was. Glistening with pre, and all Lynn could think about was sliding it into her body. Suddenly the bloated feeling in her stomach didn't feel so uncomfortable.
"No, Lynn we can't. You don't understand what will happen. The changes will only get worse!" Bree tried to get through to Lynn, but she was too far gone. Bast had hoped Bree's friend would have more willpower, but giving in to the heat always lead to fun too.
Bree on the other hand kept fighting her arousal. Though her penis was standing straight in the air, Bree refused to let Bast's spell control her. Lynn kept creeping closer and closer until Bree was forced off the couch. Lynn licked her lips, and moved her head towards Bree's cock. Her enlarged tongue ran up the length of the shaft, and then Lynn swallowed the entire five inch shaft.
Bree moaned as Lynn began to orally pleasure her. The feeling was better than anything Bree had ever experienced. So much better than using her own hands. The inside of Lynn's mouth was warm and wet. Bree couldn't help but think, that if this was what her mouth felt like, her actually pussy must be a million times better.
"Lynn... you can't... stop..." Bree moaned. But Lynn kept sucking until finally, they both reached an orgasm. Bree exploded into Lynn's mouth, her balls contracting over and over again. Lynn drank as much cum as she could before she spit Bree's cock out of her mouth.
Below, Lynn's sex dribbled fluid onto the floor, and her changes were locked into place as soon as she reached her orgasm. Her stomach finally stopped bloating, and had turned a light pink color. Her breasts were enormous, having grown from C cups to E. Her nipples were leaking white liquid, milk. And a short tail waved behind Lynn. Her horns were only about two inches long, and pure white.
When Bree reached her hands up, she found her own horns were much longer, about four or five inches to match the size of her cock. Bree shuddered at the sight her transformed penis. It was no longer human. Still only about five inches, but it was something that should be on an animal.
The skin was thicker, and a dark brown color. Not yet black, but it did have some pink spots on the shaft. The head was larger on one side than the other, creating an obvious flare. There were small bumps around the head, and a sheath ran up about half of the length. It was a mini-horsecock. Behind her, Bree's own tail was now long enough that it hit the back of her thighs. Her breasts grew another cup size, and Bree's hair was almost entirely red now.
"They're both coming along quite nicely." Bast thought, admiring their changes. Lynn's desired form was becoming more and more obvious. While Bree desired to experience the same things as a male, Lynn wanted to enhance her womanly pleasures. And the being she'd seen on the screen of the tablet reflected that appropriately.
"What... what just happened?" Lynn breathed as she recovered from her climax. When her mind cleared, she screamed at the sight of her own body, and then Bree with her tail, horns, and the five inch horsecock.
