Story where son walks in on his mother having sex with his friend?

[Sai_dias_29]

I read this long time back. The only thing I can remember is the son coming back early from school and he hears voices coming from his mother's room. He goes to check it out, only to find his mother and friend have sex. I'm not sure whether or not he interrupts them or watches and confronts his mother later.

I have one titled "Watching Mom Get Deliciously Fucked" by author Janus. I do not have a link.
