His Wife

An old buddy contracted me recently asking if I was single. When I said yes, he asked if I'd like to 'entertain' his wife.
Long story short, he knows I'm well endowed. He also knew in my teen years, I used to fuck several married women.
The first night, even though I'm a sexually confident guy, I was nervous as I've known Cal for a long time.

Anyways, without too much hanging around, she walks in their lounge wearing the sexiest lingerie and we get it on, right there in front of my buddy.

Oral sex both ways, fucking her pussy and asshole. And using toys too.
It's a great time and I bust my nut up her twice.
Two days later, he rings me and asks if I could call by and fuck her again.
I'm there in less than an hour and spend the whole afternoon screwing his wife.
When I'm leaving he tells me, anytime I want to call by, to just drop in and fuck her.

Over the next couple of weeks, not only do I fuck her with Cal there, but we have sex at their place and mine without her husband being present.

It becomes clear he can't keep up with his wife's needs, and it also becomes clear we're extremely compatible sexually.
There is nothing we don't enjoy together and now she's talking about making us a permanent thing.

In other words keeping her husband as a cuckold and having me fuck her, as and when I want to.
I spoke to Cal about it last week. His words "I'd love it".
Just have to work out now, just how it will all work.
