Hello Fancy -- welcome to AW. Looking forward to having you around.
Your first sentences are intriguing -- I want to know why Jenny is naked, what's burning her eyes, and what it is she wants to get over with! But I do have some issues with the writing.
George Orwell's famous advice for writers includes: Never use a metaphor, simile, or other figure of speech which you are used to seeing in print. "Naked as a jaybird" is a hackneyed old figure of speech -- your first sentence needs to be more arresting than a tired old expression that doesn't even really mean anything (how is "Jenny stands naked as a jaybird" different from "Jenny stands naked"?).
Is "It's burns behind her eyes" what you mean to say? It isn't grammatical and I can't figure out what it means. If it means "It burns behind her eyes" then I really think you need to tell your readers something about what "it" is -- otherwise it just doesn't make a whole lot of sense. "until ... the hot goes away" is also not strictly grammatical but with that one I can at least get the jist of what you mean, and can even imagine that "the hot" might be a deliberate variation on "the heat". Following "It's burns behind her eyes," though, I can't tell what's language play and what's just error.
Still, notwithstanding some mechanical issues, you've created an intriguing situation and you're starting right in the middle of it, which is great.
