Although both girls had ultimately decided against Christy remaining as Madison's human cock, neither of them were happy about it. Throughout the entire day, Madison's had felt as if she had lost a part of herself. Christy felt similarly too. They knew what the source was, but not exactly how to fix it in detail. The simple answer was that Christy had to become Madison's cock again. But this time, in a way that wasn't quite as dangerous.
After a boring day of school, since neither were in the mood to transform anyone, they met back up to fix their situation. "Hey Madison, umm... I kinda... er how do I put this..."
"I want you to be my cock again Christy" interrupt Madison. "All day I have been feeling like a part of me is missing, and I reqlized that its you, Christy, as my detached cock!"
"I feel the same way! All day I felt cold and empty inside. I miss being your cock" admitted Christy, feeling a huge weight lift off her chest knowing that Madison wanted her back too. "So what do we do?"
After a few hours of testing, the had finally found the perfect solution. Christy would become Madison's cock once more, but instead of a human cock, she would be closer to a cock replacement. Whenever they were seperated physically, Christy's body would actually function as a working version of Madison's cock. That meant her breasts functioned like Madison's testicles, if she managed to get off, she would vomit horse cum, she would find whatever Madison found attractive, attractive, except for herself.
Durring their tests, it had been revealed that Madison found Christy irresistibly attractive, which meant Christy would end up trying to fuck herself the moment she saw her own reflection. So Madison suggested they restore Christy's overridden sexual preferences back to her origional ones, meaning that Christy now found Madison to be irresistibly attractive, and not her own body.
Christy would also keep her mare pussy. And whenever they could afford to be, christy would let Madison's real cock be inside of her, where it would stay until they had to seperate. When they were together, Christy would hang underneath Madison's body limply with her head raised so she could still see and interact with the world. However, she would fully become Christy cock when in that state. So if Madison had to pee, it would come out of Christy's mouth, same with her cum. And Christy's entire body would become an erogenous zone, similarly to Madison's actual cock was. Christy would feel Madison's body as if she was attached to it. Lastly, if while Christy was mounted as Madison's real cock, Madison were to want to fuck something, she would use Christy to do it since Christy's body would be where her cock normally would be. In ither words, Christy would be shoved head first into the pussy which Madison wanted to fuck.
When Madison had Christy mounted, her cock's sensitive surface would be extended to Christy's skin, and would no longer be creating the pleasure loop. That being said, it would not happen immediatly, but only after an initial 10 minutes. This window was decided for when they wanted to just fuck each other as actual girlfriends (to which they agreed to officially make public knowledge the next day), and not each others body parts.
Interestingly, Christy's id now labled her as being simply a horsecock and nothing else. Christy the horsecock. Even more amusing was how all of her body's measurements had been converted into cock themed data. Breast size became ball size, height became length, waist size was her girth. Even her mouth's widest possible opening size was recorded, and somehow she had a urethral diameter number. She only could assume it was her esophagus's opening diameter. They bith had gotten a good laugh when her head was labled as "gland".
