Anythig goes apparently...

Three weeks ago I had a massive argument with my husband Phil. He'd accused me of cheating on him with an old school male friend of mine, who had stayed with us over the previous weekend. He'd found a condom wrapper under the bed and went balistic. I knew I hadn't cheated on Phil with my friend, so I became angry and accused him of using the condom.
For the next couple of days he kept on accusing me, coming out with sly remarks.
That weekend he went on his usual overnight fishing trip, but before he went, he just couldn't help himself and once again layed into me about cheating on him. Very frustrated and annoyed I got myself ready and headed out.
Sat in a bar on my own, a younger guy came over and started chatting me up. I knew he was after only one thing, but liked his cheeky wit and his handsome face. When he asked me if I'd like to share a room with him for a couple of hours I refused at first. When he told me he knew Phil quite well and I wouldn't regret the time spent with him, I followed along and we took a cab to the motel.
The sex was unbelievable. At nineteen years old he knew way more about pleasuring a woman than Phil ever would. For over an hour he took my body and senses to new sexual places. I also learned what it was to take a large thick cock, one much bigger than Phil's. It was me by the time it was time to leave two hours later, who was begging him to fuck me again.
Stopping short of our address he got out of the cab with me, walked us both over to a dark alley and for the next twenty minutes I took his huge dick up my very eager ass.
Taking his cell phone number, before he left me and my ass full of his cum, I asked how he knew Phil. He just said "ask him what he gets up to on his fishing trips". I wanted to know more but he'd walked on.
The next day I couldn't get what he'd said out of my mind. So I waited until phil had gone to work, dug around in his fishing gear and found a packet of un opened condoms, the same as was found under our bed. Straight away I phoned the young guy I'd had sex with and asked him what he meant by saying "ask Phil".
His response has changed everything, he said "Your ass isn't the only one in you marriage, which I've fucked. Phils not such a great fisher man, but he can suck and take cock just as good as you can".
I was left stunned and silent. I couldn't believe what he'd just told me until he added "You nearly caught us the other week when you came back from the mall with your friend. We had to shove everything under the bed, then I climbed out of one of the back windows, fucking half naked".
My mind was racing and finally speaking I asked what things under the bed.
Apparently anything does go, Phil and our young lover had flung a dildo, lube, two used condoms and empty condom wrappers under our bed.
To get himself out of a tight spot he'd accused me of having a fling with my friend, when all along he was having a gay affair with the same young guy who'd fucked me senseless all over the motel room.
Now I have a problem. If I tell Phil I know about his gay relationships and that he goes fishing only to get himself fucked. I'll also have to admit I've had sex with one of the same guys who has fucked him aswell.
Boy this is a mess!!!
