Kim wants to try Zoe on

Kim just silently reaches out, taking Zoe's hand, and she wanders off to the bedroom, closing the door.

You didn't object, you trusted that Zoe was here to have fun with both you and Kim and not just steal your girl, but you were just a little jealous that your lovely girlfriend and your sexy former body were off sharing a room together and you weren't in on the plan. You couldn't help but think they were in there, making out or something.

And then, the door opens, and your jaw nearly hits the floor.

Kim strolled out, slowly, carefully. Her head and face were still plenty familiar to you, you'd recognize her long orange locks anywhere, and those green eyes stared intensely at you. But your eyes trailed further down, and you saw a Kim you'd never seen before. Her breasts heaved, massive globes dangling off her chest, almost cartoonishly large, and yet sculpted so well that they seemed like Kim always looked like this. Kim didn't have clothes remotely capable of housing these breasts, so she had an open jacket partly covering her for now, if only to help heighten the illusion a bit. At her legs, seamlessly extending from her newly widened, luscious hips, she wore a bikini that barely seemed to hold in place, clearly straining under the stretch of her exaggerated hourglass body. She continued to step closer to you, until her massive chest was resting against you.

"I asked, and Zoe agreed, to give me a bit of a change. For you, to show my gratitude. I'm going to show you the best night you ever had." She spoke breathily, her own heart beating rapidly at the thrill of her new form. "Especially since you're going to become my ideal woman next time you're wearing Zoe, this seems only fair, right?"

Kim roams around you, eventually shrugging off the jacket she was wearing, until her massive tits bounced in front of you. It even seemed to catch Kim off-guard, and she moaned a little from the movement. Zoe's influence seemed to really heighten the intensity for Kim inside of her body. She ran her hands along her massive chest, jiggling the flesh as she swayed her hips slowly back and forth, alternating between looking down at her form and eyeing you, to see if you were enjoying what you saw.

Clearly you were, as Kim confirmed when she came back close to you, running a hand along your pants. "C'mon, let's see just what Zoe can do for the both of us, hmm?" Kim purred her words at you, as she leaned in close, planting her lips against yours for a deep, passionate kiss. You couldn't remember the last time Kim was even half as interested at intimacy like this, but you already knew things were going to get totally wild.
