In terms of the guidelines on this site (and particularly with regard to changes in categories and stories that have gone hidden) ... A mmf story about a father/son/unrelated-woman in which the two men don't interact with each other ... does that constitute *nc*st? Something along the lines of "dad takes son back to college, and they both end up fucking the same cheerleader in a locker room scene" or something like that. (That's not my story, I'm just making up a parallel example.) Thanks for your input!
Incest is only when two or more family members have sexual intercourse with each other, so in your parallel example it can be counted as incest only if that cheerleader is their sister or cousin, if she not related, it just ordinary rape or gangbang.
