I'm trying to find a specific story, but I'd also be interested to hear about any other stories that fit the general idea of sexual shenanigans among a gaming group. Either the players or their characters, or both. I'm not especially interested in stories that are only fantasy, but in stories that at least switch back and forth between the gamers and the game world, or even focus entirely on the gamers. If that makes sense.
Now, the specific story I'm trying to find. A woman plays a solo D&D (or D&D-ish) adventure with a male DM. She plays a thief who's trying to steal from a wizard. The wizard catches the thief and chains her up, at which point the DM ties the player to the wall and plays with her the same way the wizard is playing with the thief. One specific detail I remember is that the next time the player brings her thief character into the larger gaming group, the character's alignment has changed from Chaotic Good to I think Neutral Evil, and the wizard is now her patron.
I think it's been a good fifteen years since I read this story, and I have no idea what reminded me of it, so I don't really have high hopes of finding it. But this site has surprised me before, so I figured it was worth a shot.
