Looking for Forgotten Story by Description of Plot

So I've been looking for some stories I'm pretty sure were here under the Mind Control theme. The first one was a serial that had a theme tied in with DnD, where there would be someone given some sort of power by a stat-quoting wizard at the beginning and would end with a quote from the wizard outside of the story. They weren't technically connected other than the fact that the wizard was in all of them, and the story I'm specifically remembering is one about a rough, macho guy who takes a ring from the wizard making him really attractive to women for the first day, ending up in him fucking a few women. The next day, he turns into an airheaded but tremendously attractive woman who ends up fucking his-turned-her landlord (with the landlord not knowing he was fucking his previous tenant).

Anyone have a clue as to the title of the series?
