Your girlfriend tourns back to you, her grey lips. "Well, what do you think, hun?"
"It looks great, I love it," you answer. "But it does look a bit unnatural."
"Yeah, you're right. But come to think of it, it feels unnatural too." She smacked her lips. "It's like my mouth is covered in latex or something."
You took a closer look at her face. Her lips were glossy and had plumped up considerably. You traced a finger over her mouth. It was smooth. It's still soft, but more like silicone.

She drops her arms, and the changes seem to be finished. You gawk up and down her hourglass figure, resting your eyes on her hips. For a machine, she was positively sexy, her skin smooth like silicon.
Her body shuddered again, and she springs back to life. Facing you, she says:
