This is part of a linked set of stories about a family. It consists of several parts; this is part 4 and tells the story, taking it up after the events that occurred at the end of part 2, and giving the wife's view of events.
This is not a stand-alone story so it is best to read parts 1,2 and 3 first.
Everyone taking part in sex acts, is over the age of 18.

As I lay on the floor of our lounge gaining back my breath, after a very vigorous fucking, I think I knew our families' lives had changed.
I'd been cheating, all our marriage, but I'd always ensured that Robbie was kept in the dark.
It wasn't that Robbie was a fool. The only reason that I'd been able to keep things undercover was because he had always trusted me.
Gordon's extrovert nature and the fact that he had always acted in a sexual manner towards me, and the girls, had covered the reality that he had been fucking me for years.
Not that he was a better lover than Robbie, in truth he was such an arrogant, conceited lover, he just took what he wanted and the only reason I ever had a orgasm with him before today, was the naughtiness of it all.
Gordon wrongly thought that the girls might be his, I never told him, but the girls had different fathers. Neither were Gordon's or Robbie's. I admit it, I'm a cheat, a liar and a slut. Now, I'm a whore.
I don't know why Gordon paid this time, he's so stingy. I think it was so he could out me and hurt Robbie, his younger brother. Of course, Robbie would now demand DNA tests on the girls' and when everything came out in the open, our family life would be destroyed.
We had only one hope. Robbie had been gobsmacked when we arranged the gangbang for the next Friday. But, he had said that although he wouldn't accept being a willing cuckold, he would accept being our pimp. I didn't believe it but it was something I hoped he might consider.
He had left before I could clean myself off. Gordons cum was running from my cunt and down my leg. I guess the thrill of outing me and destroying his brother, had caused him to deliver a big load. He was a real shit, poor lover, dreadful son and a bastard brother in a literal sense. Unable to catch Robbie, I returned to the living room, still naked.
"You're a real bastard Gordon. Why did you do that? It's been a secret for years, and you've benefited from it more than anyone. What's going to happen the next you can't find anywhere else sleep. You're not going to be welcome here."
