I read this months ago and I thought I saved it somewhere, but I didn't. The only thing I can remember from it was a scene where the father is getting a blowjob under his desk, while having a conversation/meeting with his son or employee? After the meeting is over his wife comes into his office and joins in. This scene takes place at the beginning of the story.
I was the thought the story was "Land of Cotton", but I can't find that scene in the story.
Edit: More of what I remember
The conversation was about how the son(?) Is doing a great job, and how the dad is excited about him taking over. The son(?) Doesn't know the dad is getting a blowjob while they're talking. Also, the mother Joins in, in the following chapter.
Update: FOUND THE STORY!
