Is this meant to mean like TTRPG PCs? If so, I haven't actually done this before. My characters have only ever been in relationships with NPCs. However, my DM DID write his OWN pornographic encounters for those characters in his campaign that were involved with NPCs, and shared them with the players.

yes, all of this.
i guess i just dont know the other players enough to share,
....im also very concerned that the things i smutty write could influence the plot

-laughs in DM-

if you were my DM it'd be impossible to hide my smut from you LMAO!!

Nah, I just shoot fun fantasies at you with Drizzt and another dragon you know and love

god yes!
