I hear you, I said it in an earlier tread , these type stories always go way past the edge. It starts with the husband wanting it to happen when it does he'll show some concern about a few things. Maybe even say something to wife about how she's acting toward the guy like she maybe getting to involved. But like always in these stories she'll start lying and going behind the husband's back and if he finds out he'll try and get mad but they more he thinks about it the more he jerks off to it. In the end she'll do whatever she wants to do and the more she fucks around on him the more he'll jerk off. It's the same troupe.
There's been only one story, that I've read, where the husband has actually changed his mind about things and stood up and left. So only one writer has actually had the balls to deviant from the norm. Series is called Cuckold Consequence's by RoleplayLiterate
