Cuckholding Stories Where Dad is Forced to Watch

[AllyGirl84]

I think I posted something similar to this a while back. Most stories of these nature always have the father walking in and suddenly dying of a heart attack or something. Any recommendations for stories where the father knows about the relationship between mother and son and is unable to stop it?

This may not be 100% what you're looking for but this is a story about the father knowing about the relationship. I don't want to spoil but stick with it.
