Fics like The Lust Virus

When Arthur Watts infected Penny Polendina with his virus, he added a not-so-little side effect that he hoped would please Salem greatly. It would take a while for it to take effect, but once it did, Penny would never be the same again. At the Schnee Manor, when the side effect of the virus finally activates, Penny sets her sights on her best friend. Has Ruby always looked so irresistibly sexy? She doesn't know but she doesn't particularly care. She just wants to fuck Ruby's brains out.
