Kim interrupts the process

Kim holds up her hand before anything happens. "Wait! Wait. Don't do anything."

You tilted your head, staring at Kim. "What's the matter? I'm just going to--"

"I don't want to know about the how. I don't want the behind the scenes, not right now. All I know is there's a beautiful woman standing in my apartment that I can kiss and hold without damaging my relationship with my boyfriend. Let's not reveal whatever the magic is you've done, let's just... just..."

You were surprised when Kim threw herself at you! She wraps her arms around you, and kissed your lips, deeply and passionately. Your new mass on your chest collided with Kim's in a way that certainly grabbed your attention, but you tried to push it out of your mind while focusing on your girlfriend, wrapping your arms around her in return. You were slightly shorter in this new body, meaning it was easier to kiss Kim without her needing to get up on her toes if you don't bend down. In essence, you were a better fit for her now, size-wise, than before.

And Kim clearly loved it. You were on the inside, but that feminine exterior with just the right touch of tomboy to match your personality, maybe Zoe actually did too good of a job. If Kim enjoyed this new body with your mind in charge, would she be able to settle for the normal you anymore?

You pushed that thought from your mind. It wasn't important, and that can be worked out later. You kissed her deeply, holding her tight, just like you'd wanted to do every night, until you'd begun to grow distant.

"It's a perfect fit, huh?" Zoe mused rhetorically in your ear. Kim wasn't able to hear her, so she felt free to talk to you. "I can tell that Kim is excited, her body language indicates that maybe you'll want to get seated sooner rather than later. If I might recommend? Let her do as she likes, once you're settled in somewhere."

You nuzzled Kim, using Zoe's body to maximum effect as you rested close to her. It wasn't just how you looked, or felt, or sounded--all of those were the obvious things to you. You didn't realize until Kim rested her head to your neck, inhaling deeply that you likely had a different scent, a flowery aroma that was something Zoe had worn earlier that day. And in the kiss, you probably had a very different taste. The illusion was plenty complete, Kim was immersed in the new you, and it spurred her on further as she took your hands, tugging you toward the couch. You happily complied, hurrying to take a seat, as Kim sat on your lap.

She reached down, pulling up your tee until your breasts were freed, tugging it off your head as she sighed happily in the sight. Her hands roamed along your neck, down your chest, searching for seams or some other sign that of this body being merely a costume or clever prosthetic, despite her insistence that she didn't want to know. You knew that she couldn't let something like that go, and anything that broke immersion would kill the mood. So more and more, as she saw just how real your body really was, she grew increasingly excited. Kim fumbled with your bra--a strange turn of events--as she pulled the fabric away, letting your breasts spill free. Her hands cupped them, and you jolted a little. "Ah, your hands are a little chilly...!"

"I can't believe it, these are real... they're really real. Logan, I..." She trailed off for a bit, her hands trembling a little as she slid her hands along your side, down to your midsection. "Even when you first showed up like this, even with how you sound and what you asserted, I thought it was some clever illusion. This is... it's perfect."

Her hands gripped your breasts harder, still trying to search for a flaw, or a seam, or something obvious, but Zoe's body was immaculate, and designed to be undetectable once she was sealed up. Kim could search every inch of you and not find a flaw. And you were probably going to let her, at this rate.
