Crosses And Cheats

We all have our crosses to bare. Mine is cheating on my first wife (who i'd married when we were both only twenty) with her brother Corey when she died.
We were actually in his bed fucking, when I got the phone call from my wife's workplace.
She'd had a seizure and had died in the ambulance on her way to hospital.
After the funeral I moved away, not only because of what had happened with my wife and Corey, but also I had to get my life back into some sort of focus.
For three years I didn't date a female, although I kind of went into overdrive fucking young guys in my new apartment.
It was all to cover over what had happened, yet as quickly as I started fucking young men, I stopped.
Some time passed and then I met Lucy. We dated, fell for each other and eventually two years later we married.
Before we married I knew she couldn't have kids, but I was fine with that and got on with enjoying myself with a stunning looking woman.
Then I learned only months after tying the knot, she used to have sex with her brother Rial as teenagers. How I found out, was through a woman who used to be Rial's girlfriend not long after they moved over from the Czech Republic. And given certain things she said, I knew it was true.
When I spoke to my wife about it, she didn't deny it, but very calmly said "Who said we ever stopped".
It all clicked in then. The times she returned home late from visiting him. Or the times they'd go into my wife's painting studio at home, and normally so well presented, she looked like she'd been dragged through a hedge when they walked back into the house.
What's the saying, 'If you can't beat em, join them'. Well kind of.
To me it was my Karma returning to bite my arse. So instead of going crazy, a few days later I invited Rial around without Lucy knowing.
And as it turned out, not only do they still have sex, but Rial, unknown to me before, enjoys cock down his throat and up his arse.
Lucy got in from work precisely when I knew she would. And her face when she saw me knelt up naked and balls deep up her brothers arse, will stay with me forever.
There was nothing she could say, nothing.
And she knew it.
So like the guy I used to be, I carried on fucking Lucy's brother right there in front of her.
She started to say lots of things, as I continued to bury my cock up Rial's arsehole. But didn't actually say anything. Then after a few minutes of stamping around, she walked out.
Lucy moved back over to the Czech Republic five days later. Rial stayed. And I've been fucking him ever since when he's been at my new home. He's completely in love with me, and that's truly genuine. He wants to move in permanently, but I'm not so sure I want to engage in a long term relationship with someone who can hide that he used to sleep with his sister.
And besides, how would I continue to fuck the neighbours son if Rial moved in.
