I don't remember anything about the story other than some parts of the plot as listed below:
The story contains a husband instigates his wife to have sex with a younger man. The wife reluctantly agrees and then uses her son as the younger guy.
The husband wants to see them at it. The wife agrees on the condition that he has to hide in the closet, and he won't try to discover the young guy's identity.
The sex happens with the son wearing something hooded, but at the end the husband comes out and pulls at the hood and sees their son, who runs out.
The story ends with the following scene: Instead of exploding with rage, the husband instead asks the wife how she's managed to convince the son into having sex.
I've tried tag search and targeted google site search, but I have not been able to find that story again.
