Bloodlust

Sunset gets bitten by a mysterious bat she's never seen in the human world before, and it seems to have some side affects on her.

Sunset is bitten by a bat that appears to just not exist in the human realm when she researches it. After the bite she's starting to experience some weird after symptoms, and has completely lost her appetite, but has a weird craving.

For the sex tag, there's no explicit sex just some suggestive scenes, and talk of it.
