"Care for a jog?" You ask. The thought of her jogging causing milk to fling everywhere you guys went made you very excited.
"I don't mind, but only if you can do one thing for me." She said.
"Done"
"But I haven't even said what I want you to do yet."
"Right. Well I likely would be cool with doing it anyways." You say, trying to cover up your excessive eagerness to see her milk faucets bounce around.
"If you insist then." She said, walking up to you. She grabbed your legs with her lower arms and your arms with her upper ones. She wraps your legs around her waist, so that your clits are rubbing each other. You tighten your legs, securing you in place. She then repurposes her lower arms, using them to line up her nipples with your own. One in place she pulls tour arms around her back, pushing your smaller but harder nipples into her own larger and softer ones. She wraps her own lower arms around your ass, cupping both of your cheeks which doubles at keeping you stuck in place.
With this, she begins to jog while carrying you. She apparently was way stronger than she looked. As she went, your nipples, still very hard, and extremely sensitive had begun to dig into her own, creating a tight, but very strong suctioning seal. Now as her tits bounced around, her nipples yanked yours around too. You felt like each of your boobs gained 10 pounds.
30 minutes of constant jogging later, you both were sweating pretty hard. You were satisfied, but not exactly how you were expecting to be. About 10 minutes in, your body began to perceive her boobs as being your own. You felt every bounch, every jiggle, and every drop of milk stored inside of them.
"So, how was it?" Alexis asked.
"Not what I was expecting, but still very nice." You honestly answer.
"Haha, I bet you wanted me to spray milk around with every step right?"
"Y-yeah, something like that?" She sets you down but still holds you close to her. Your nipples were still trapped inside of her boobs too. Giving you a hug, she releases her arms letting you take a step back so you were not standing quite on top of each other, or you would have.
The moment she took a step back you were pulled forward by your tits, causing you to trip and stimple. But that too was prevented by her tits. Your nipples were seriously stuck together.
A look of panic appeared on both of your faces. Neither of you had expected or wanted this. "Don't misunderstand, I mearly was using you as a bra. I didn't know something like this was even possible!" Alexis quickly explains.
"Don't worry, I am not blaming you. But maybe we should get some help." You propose. She nods and picks you back up. Apparently she was intending on carring you to the help station.
Once their, you are examined by the personal. Apparently, whoever had these tits before had spiked them with some of their transformation oils before sending them to Alexis. As it was, your boobs had merged into each others, making you literally share them. Your boobs were seamlessly connected to hers. That at least explains why you felt her milk and such as if it were your own.
"Wait, where are our nipples then?" You ask. The attendant helps you get a view of the sides of your boobs. Half way between the both of you, a merged version of your nipples have appeared, sticking out to the side now, instead of the front since that was no longer an option. They had Alexis' size, but your hardness and sensitivity. Plus they were trickling milk now. A tiny but steady stream poured out of either one. It had enough force though to not run down your boobs too. A worker, along with Liz, comes up to you both.
"Well, this certainly is new. I am so sorry about this sweeties." Liz starts, giving you both a "group hug". "Are you in any pain or feel like anything is about to break?"
"I think we are fine in that reguard, Mom. We just are merged together is all." Alexis answered.
"Wait, Lis is your Mom?" You ask shocked.
"Adoptive, but yes! That is my beautiful daughter you are merged with." Liz answers, which in tern causes Alexis to blush. "Hypothetically speaking, I wonder if that now makes you also my daughter? Temporarily of course."
"Please don't make the awkward Mom." Begged Alexis.
"Very well dear. Now then, unfortunately it will take us a bit of time to seperate you both. So while it isn't a problem for Alexis, since she lives here, what about you? Is there anyone we should contact for you? Or something you need? You should plan on staying here for about 2 weeks. Hopefully less, but possibly also longer. We will not charge you for it at all, and will comp everything for you as an apology for the inconvenience. As for your work, we can technically write this off as a medical emergency/injury, so you should not need to worry. We will handle everything for you."
"Thank you for offering to do that, but 2 weeks?" You couldnt believe you were going to have to share a body for 2 whole weeks, fully naked, while being carried around if not acting as a bra for Alexis. This was either a dream come true or a nightmare. Maybe even both.
"Again, that is only our best estimate. But optimistically speaking, it shouldn't take that long. However the opposite is also true too." Walking over to an medicine window, Liz picks up a vial of some kind of gray liquid. "This is my best proposal to make your stay here as easy and comfortable as possible. This vial will further merge you too together, and reform your body slightly into a better suited shape. You should end up being a centaur like being, except human in shape. Your upper torsos would remain split (aside from your shared boobs) and would be facing each other. You would need to work on walking together, but it is better than one of you carrying around the other. We would also bulk up your lower body in order to counterweight your upper half, by adding on an udder near the back. And I am certain we could fine someone's hair to use if you wanted a tail. We would even pay you since this is still a new concept and has only limited testing. But has yet to produce a bad result. You would be considered a temporary test subject, and would be contracted as such. Of course if once this is over with, we could renegotiate to hire you on full time if you wanted to. But this is for a later conversation and I am getting off focus. So what will you choose, it is entirely up to you?"
