It Was At Her Insistence.

My wife told me, I either submit to her demands, or I won't be fucking her anytime soon.
The reason she wanted me to go along with her demand, is I'd persuaded her to have a threesome with a hot girl when we were on holiday in May.
I fucked them both and watched as my wife and the nineteen year old had lesbian sex.

Back at home my wife told me we needed to reverse the roles and have a bisexual guy join us. One that would fuck me.
I said no at first, yet my wife is sooo horny looking and extremely sexy, I eventually relented.
It didn't happen straight away (Start of July), but after lots of chats with men online on a couple of swinger sites, we finally agreed on a forty six year old guy called Tom.

I was nervous at first when he arrived at our home, but my wife was so up for it.
After a couple of drinks and lots of laughter as we chatted, we got naked and headed upstairs.
Tom's cock looked way bigger in the flesh so to speak and my wife was soon sucking on it.
She got most of the attention to begin with, that was until I was pretty much made to give Tom a blow job.
And what shocked me, is my wife and I found out I could suck cock just as good of not better than her. In fact even though it was my first ever time sucking dick, I was able to deep throat Tom's full length.
Tom and I then went on to fuck my wife taking turns, and as I was fucking her missionary, he lubed up my rear and slowly at her insistence, entered me.
It was weird because I was fucking my wife which felt good, but no where near as good as the feeling up my arsehole eventually became.
It was so powerful a feeling, when I finally came inside my wife's pussy with her having a really violent orgasm, it felt like my arsehole was having a huge orgasm too.
We all moved then, but Tom pulled me up to a kneeling position. And as my wife watched, he fucked me incessantly doggy fashion until he came inside me, filling the condom he had on.

We all went downstairs and had another drink, then Tom said he should go. He'd arrived in a taxi, but my wife told me to drive Tom home.
It was a fifteen minute journey that lasted an hour and a half.
That's because Tom had me sucking on his cock, then he fucked me over the boot of my car, in a lay by down a quiet dark country lane.
After he'd cum all over my arse cheeks, he told me he was more into young guys like me, than women.
I told my wife the following morning (she was asleep when I got back) that Tom and I had talked about the night and that's why I was so long.

And since that night, Tom has fucked me many times, with us often fucking outdoors or in each others cars.
We now fuck bareback as I love the feeling of his sticky hot spunk filling my rear hole. We've both been tested, so as far as I'm concerned at the moment, my arsehole is all his.
