Gentle Manne, just a heads up: Vesper's not naked, ahhaha!
And the spikes are coming from her back, like a Gengar. But! I wasn't clear. At all. Now that I read it even I'm confused. So I'll go fix mine and you can go fix yours? Naked Vesper just sounds awwwwk. I'll put this in instead:
She ripped off her blazer. I must be insane. She ripped off her blouse. I must be insane. The black, close-fitting halter underneath her clothes covered her front and left her white back bare, where purple-black spikes sprang up like the volatile aft of a Gengar.
