"What?" The Mary's say in unison again. Surprised at and shocked at the thought of never being able to be fully separate to each other. "But we are the same person!" they respond as the witch starts to make a new vial taking a drop from female and cow. "You'll become different over time, just as identical twins do. Simply being in the presence of your self makes you act different." She says taking out her own flask from her hat and pouring some of it's contents in. "Speaking of which I'm giving you each new names, though they are fairly similar to your current ones." She says when the mary on the left objects, "What? But I'm the first mary I shouldn't have to change my." A look at her double reminding her of the conversation of who was who from earlier she stops and nods. "Yeah... okay What did you have in mind?" Taking a paper The witch etches a symbol on the back and writes, "general fix for maries." on the front. "Well I think you'll be Mari, and you'll be Marie." She says motioning to the right then left mary's.
Finished with the vial the witch gives it to Mari first, "Drink it all, no halves for this one." She instructs as Mari swallows the concoction quickly, the vial like the others refilling itself before it is offered to Marie. "You to, both of you need to take a full dose." The witch smiling as Marie gulps it down and watching her experiment. "Hope you enjoy this... more stable form. This vial will send you back to this new one any time." She says setting it in the vial tray. "Also, you can swap places if you both agree to." She adds a bit cryptically.
The pressure easing for the moment, mari and marie feel a stretching form their shoulders as nubs pull out beginning their returning arms, their breasts releasing and splitting from each other as well. Marie starts to go a general pink color while Mari has the return of her bovine like ears and some increased white and black spotted fur on their back and ears. Their positions shift as the Larger shared udder disappears as they seem to be connected at the hip now. they lay across from each other on the couch, Mari getting the feeling of an udder returning to her confusion as she doesn't see one, while Marie feels her nerves sharpen and increase in her causing her to feel very sensitive. No legs come back but both having a set of arms is more than enough of a change to their situation. Their tails fuse together and Mari feels milk in her mysterious udder while Marie feels a full feeling as some liquid is filling a lot of her, making her breasts and stomach area inflated.
"Marie... Do you see an udder, I feel one but I can't see it."
"Sorry Mari I don't... unless..." She says having an idea at the last moment. "Mari I might have figured it out." She says leaning up, showing a massive increase in their spines flexibility and leaning on top of Marie, "What is it?" She asked before being quited and her face guided to Marie's breast, taking a suckle she is shocked to find milk, more creamy and delightful come out of it. "Marie... does this mean?" Mari asks as Marie nods, "I think so, I'm your udder." She shudders at the intense almost climatic feeling of being suckled by her other half.
Being shocked in to silence the witch speaks up. "I'll be... far closer to you two for now on, to make sure you don't almost mess yourself up again, but have fun with your self and the vials, I'll be making a basement for myself." She says a door appearing in front of her on the wall she opens up and heads down the stairs, it seemed almost normal now to the two who were once Mary. Mari is the first to speak, "I think you need to be milked Marie." She says with a teasing grin.
