Back to Katie's apartment

“Fuck, that was hot.” Katie exclaims, tossing her head back with relief as you drive away. You glance over at her. She's still squirming in her seat like she was before, but now it looks far more relaxed and erotic.

“How are you feeling?” You ask, unable to keep yourself from look over at her.

“Wonderful.” Katie purrs delightfully, closing her eyes and letting her hips grind into the seat ever so slightly in a gentle rhythm, as if fucking an invisible cock. “We're getting along so much better than before.”

Katie is panting louder now, clutching at the door and center console as she moans loudly. Clearly unable to control whatever is happening to her and, frankly, looking like she doesn't want to.

You press down on the accelerator a little harder. You're not sure what good getting her home will do, but watching your girlfriend being pleasured like this while trying to focus on the road is maddening.

You drive up to her building just as she screams her way through a second orgasm, leaving her exhausted and panting.

“Come on. Let's get you inside.” You encourage her. She nods weakly and allows you to help her to her feet.

“Fuck.” She groans, leaning against you heavily as you walk awkwardly to her apartment. “It's so fucking good, but it just doesn't stop.”

The door to her apartment isn't even closed before she begins stripping off her dress, sliding out of it as if its utterly foreign to her.

“That's better.” She grins, turning to face you. You look down at her and notice something immediately.

“It's changed.” You remark, running your hands over her breasts. The glossy texture of the material is still there, but flush with her skin now, as if completely fused with her flesh. It looks almost tattooed onto her. There's also quite a bit less of it, all of the straps across her back having vanished.

She dismisses your concerns. “Shut up and kiss me.” Launching herself against you so forcefully that you actually stumble backward against the door, Katie mashes her mouth against yours, exploring it with her tongue as she claws at your body.

“God I want you inside me.” She moans, excitedly tugging at the buttons of your shirt. With your mind clouded by lust and eager to fuck, it actually takes you a moment to process what she's just said.

“Um... babe?” You interject, pulling away. “That could be a problem.”

She looks at you blankly for a moment, then her eyes widen in horror. “Oh fuck. Fuckfuckfuck.” She curses repeatedly. Then, almost as quickly, a mischievous sparkle hits her eyes.

“I've got a solution. And I think you'll like it.”
