Show, don't tell

"I don't want to know a single thing about it right now, I just want to... how to put it. I want to just experience whatever it is you two can do with me, like what is described in Project Inside Out."

That was an uncharacteristically bold assertion to make, but it was driven by your need to learn more and your concern that explanations will just go over your head in the moment anyway. You were so distracted by what Zoe and Chloe could already do together that it was stirring something deep within you, and now it was time to just go with the flow.

"You're... sure?" Zoe said, mouth left hanging wide open after she spoke. She thought she had a good handle on you needing time to adjust to the idea of Zoe and Chloe being so different, but either she underestimated you or seeing a face on a crotch fighting for control of a body just sort of broke you. But in a good way. In a way where you were excited that you were being invited to join in, and you could get to know the details after everything was done.

You nodded, slowly. "What do you need me to do?"

Chloe was less dumbfounded, being the adaptable type to take charge, herself. "Well, if you want essentially to replicate our greatest experiment, then all you really need to do is stay calm. Pretend you're an injured person, maybe there was some sort of serious accident in the lab. In that case, just stay put and we'll do the rest." The slimegirl slid closer to you, not in an aggressive way or anything, just getting a little closer.

You surprised yourself with how calm you were about this. It helped that you'd just seen Zoe in her underwear moments before, that seemed to be the best distraction of all. And now from what you understood, Zoe would be encasing you, while Chloe would be within you... this was the weirdest thing to happen at work to you, by far, but possibly the most enjoyable to think about.

Zoe stepped over to you too. "Just like Chloe said, just relax. We'll make it quick and then... well, I'm sure you'll surprise us yourself once we're done!" Both Chloe and Zoe were elated by your response, it was just so hard for them to come to grips with it that everyone just sort of focused on this one moment.

And then... it began. Chloe lost her shape, as transparent green slime **** its way to your mouth, flowing into you with incredible ****, yet being slippery enough to avoid any resistance--you don't think you could stop Chloe's entry into your body even if you wanted to! But again, you volunteered for this... you closed your eyes, trying to get a grip on the strange sensations flowing into you. Soon, you had to contend with what was happening outside of you too, as Zoe removed her lab coat and her body opened up in multiple locations, wrapping around you and the remainder of Chloe like a big blanket from above. The warmth you felt wrap around your legs and arms hugged you tightly, as Zoe sealed up her body wherever she was able to get fully around you. Your torso was enveloped next, but your head remained free for just long enough for Chloe to finish pulling all her slime into your body, slithering down your throat and into your stomach. You felt huge at the waist and stomach from Chloe's slime, it felt like you should be bulging widely at the midsection, but once Zoe's head wrapped around your and sealed up...

You looked down. No sign of a bulge, although the sensation was there. No sign of anything being wrong, technically. However, one thing was obvious: you were in Zoe's body, you looked exactly like her, and you seemed to be able to move her hands, legs, and head freely. Your hands immediately rested on the stomach, feeling where Chloe still existed within you as a giant mass of slime, but seeing no outward effect. Your hands trailed up along Zoe's bra, tickling the breasts a little, then up to your face. This really was you, and you were in control of Dr. Hildebrand!

Or, you were. You felt a coldness percolate up your throat, before your mouth starts to move on your own. "Wow, you know, I am thoroughly impressed that you withstood all that on your first time!" It was unmistakably Chloe's speech patterns, with Zoe's voice. You were surprised to hear yourself speak, but given that you were lounging around in a sexy, curvaceous body of one of the most respected doctors on campus and you were wearing only her underwear, it was par for the course.

Just like you'd committed to, you just went with the flow. And the results were amazing!
