Anybody have any good recommendations for stories where parents are forced to watch their daughters have sex? Not necessarily forced/NC for the daughter (although that could be an element). Bonus points if one of the parents is against it (eg Perfect Angel by P. Phantom). Also bonus points if the parent(s) help against the wishes of a reluctant daughter.
That may be a bit too specific, but someone suggested Perfect Angel and Bad Girls by P. Phantom and that got me thinking.
Thank you if anybody has any suggestions.
