Jane is a slut

We were young when we met, Jane was 22 and I was 23 but, we were mature for our age, we'd lived varied lives and had all manner of experiences having both left home at the earliest opportunity. Sex wise, we were probably more experienced than most people of our age. We fell in love and about a year later we got married.
As with all couples, we were constantly discovering what made each other tick. We got on well and always manage to sort out our differences and problems.

Anyway, not long after we got married we had what turned into a heated discussion about Jane flirting with some guy.. I really didn't mind but, initially, she denied it. Then, after much talking and tears, for some reason it all came out - before and up to when we got married, Jane had been having a casual affair with her former boss! They basically just met up for sex.
I was really shocked but, strangely, I wasn't at all annoyed by her betrayal, I was intrigued and, I have to admit, more than a little turned-on at hearing her confession.
I'd met Barry, Jane's former boss, a few times and never suspected a thing.. why would I? Barry was married, balding, an overweight plain looking guy in his fifties. Jane was young and pretty, with big boobs on a curvy figure and long blonde hair.. she was a head-turner!

Reluctantly, Jane also admitted that she had met Barry a couple of times since we'd been married!!
Over several hours, I got her to tell me all about him and their time together, then.. we had the best sex we'd ever had!
I realised then that I was a voyeur or cuck or something, I don't know, but, it turned me on massively knowing I'd married a complete and utter slut.. I love it. Jane admitted she was a slut.. she needed regular sex, much more than me, so, we came to an agreement - she could have sex with other guys but, she must tell me about it afterwards.

Things progressed quickly, I encouraged Jane to meet up with Barry again and, she did!
Within seconds he'd replied to her message, and a couple of days later Barry was around our place. Jane had told him I was away at work, Barry replied that he'd come around from work but, couldn't stay long as his wife would be expecting him.
I can't explain how excited I was, I had a permanent hard-on for days. Jane had told me that Barry had a big cock, long and thick and.. he always made her cum - apparently he was good with his fingers.

I went down the pub before Barry got there, and left Jane to it. The next couple of hours were slow and painful. Eventually I got a message from her and rushed home.
Jane opened the door to me wearing just her dressing gown and a big smile. 'Phew, I think he needed that' she giggled as she shut the front door and.. I fucked her right there, in the hallway on the carpet.
I pulled her gown open, quickly looked her up and down, her tits were bright pink with red streaks where she'd been mauled by Barry. I dragged her to the floor and pushed my cock straight in.. her pussy felt loose, squelching as I banged into her. It wasn't long before my spunk had joined Barry's, deep inside Jane.

Jane went on to have sex with Barry two more times (that I was aware of!), both times when I actually was away at work. She told me all about it, I loved it and her telling me how he made her cum was a huge turn-on. I really wanted to watch them fucking but, it wasn't to be sadly.
From that day on, I wanted Jane to show me how much of a slut she was.
