Church Goers ?

It's been almost a year since I found out my wife cheated on me with another church member.
The main reason I didn't confront them both straight away, is as soon as I got the video of them fucking in her car, I went round to my wifes younger sisters home and fucked the shit out of her.
It was my wifes sister who'd videoed them, then sent me the film.
She'd been passing the church and recognised her sisters distinctive car parked right at the back of the car park. Wanting to speak to her, she pulled up, walked over and witnessed her sister committing adultery. The man involved was well known in our community and used to be a senior member of our church congregation.
The message Ellie-Louise gave me with the video was "Don't get angry, get even. Call round I'll be waiting for you".
As soon as I entered my sister in laws apartment, she kissed me with passion and my revenge went from there. It quickly became apparent Ellie-Louise had wanted me sexually for some time, so I indulged her and myself in sexual acts I'd never done before.
The sex really was the best sex I've ever experienced and in fucking my sister in laws mouth, pussy and asshole over and over again, I got to witness a true sexual nymphomaniac, as she continually orgasmed multiple times.
By the time Ellie-Louise and I had stopped having sex the first time, I'd cum twice, once in her mouth and once up her arsehole, somewhere she adores being fucked. And I was absolutely worn out.
We lay on her bed naked for some time, and talked about what she'd witnessed and how I should respond from that point onwards. And what we spoke about before my sister in law practically sat on my face to suck my cock back to life, has now materialised.
The senior member of our church community and his sanctimonious wife has moved away soon after I spoke with him. I didn't give him a choice.
And nearly a year on I'm preparing to move away with Ellie-Louise.
It's taken lots of work and saving every penny I could, doing overtime and working a second job, but my sister in law and I are buying a house in another town where I'm soon to transfer jobs.
I'm ready now to leave my wife and file for divorce using the video, and have put an engagement ring on Ellie-Louise's finger. She's recently told me I'm the love of her life and I'm going to make my sister in law, my wife.
My wife, as far as I'm concerned can go and fuck as many fifty somethings as she wants, as our life together is over.
