Marrying My Father In Law?

My father in law Ron, who's fifty six, has an unbelievably thick cock. It's thicker than my wrist and around seven inches long.
I know this because every weekend when his son plays golf, Ron fucks my mouth, pussy and arsehole with it.
My husband is a golf professional, so that pretty much makes me a golfing widow. And having needs, I turned to Ron originally to help convince his son he should be paying more attention to me.
Unfortunately my husband's answer was to book himself and two friends on a long golfing weekend away.
That was the final straw for me, so I asked Ron if he'd call by.
Wearing only a see through pair of knickers I invited my father in law in and told him, if he didn't fuck me, I'd find someone outside of the family to cheat on his son with.
In less than five minutes Ron was sat on our sofa, his trousers around his ankles and I was attempting to suck on his hardening cock.
The sex we had over the next hour or so, was some of the best sex I've ever experienced. And the only person to have bettered that experience, is Ron himself over the last twelve months.
Whenever I'm feeling horny, which is all the time when I'm thinking of my father in law, I'll message Ron and either have him call round, or I'll take the dog out and meet him in the woods close to his cottage.
We've fucked many times in those woods, and I just love being naked outdoors with Rons thick penis driving me from one orgasm to another.
There is a twist to my confession however.
I've just recently found out my husband is also enjoying cock (He left his lap top open, and on a video of him being fucked by a guy I know well, when he went to accept a delivery off a courier) . And that's why we hardly ever have sex now. One of his golfing buddy's has been fucking my husband for over two years (Something I found out a few days ago) so now I don't feel guilty at all for having sex with his father.
However I'd like to permanently make myself and Ron an item. But I'm afraid it'll not go down well with his son. He doesn't know his father is fucking me, nor does he know Ron and I have fallen in love.
Ron (He's a widower) told me only a couple of weeks ago, he'd love me to move into his cottage with him.
I'm so tempted to just confront my husband with everything, but I don't want to mess everything up myself and Ron have together.
So, what do I do.
