The Scent of Evil (Mind control, masturbation, transformation, vampire) by Cantraps
A woman buys her sister a unique perfume, and her sister and friends accidentally learn just how special that perfume is.
A fun, quick, and hot transformation tale. It is very much a wish fulfillment story. What is most interesting, though, is how the different desires have their own degrees of power. One desire in particular literally overwhelms all the others. The visuals are excellent, as is the dialogue. However, the somewhat lower res of the uploaded pages can make the text bubbles a bit blurry. That nitpick is fully overpowered by just wow hot this all was.
