I'd Love To Be Involved

Listening to, then actually watching my husband being fucked, was a whole new sexual high for me.
He didn't know I'd arrived home that evening, a day early because I wanted to surprise him. So entering our home I immediately heard his voice saying "Oh yeh, that's it, fuck me with your big cock".
His voice had a pleading needy tone, one I instantly understood.
You see my husband has a big dick too, and his words plus the genuine feeling he put into offering himself up to be fucked, sounded just like me when he fucked my pussy and arse.
It turned me on as I continued to listen, with each moan and comment making me more and more horny.
I decided to see if I could move up to the lounge door and watch.
And I got lucky.
They obviously wasn't expecting me and hadn't closed the living room door. So I crept up, looked through the gap and saw my husband knelt up naked on the couch with an older man, also naked, stood behind my husband, ramming his cock hard up my husband's arse.
It to me was such a beautiful sight, one I wanted to view up close. However I somehow knew if I strode in I'd destroy that wonderful moment.
So I stood touching myself as I became their voyeur.
It was electric watching them fuck and it genuinely was one of the most erotic experiences of my life.
And when they changed position so my husband was on his back, I could actually see the older mans cock sliding into my husband's arsehole as they kissed.
I'm not overstating this, I very nearly orgasmed when they clinched to kiss as they fucked.
Even so I decided to leave and booked myself into a hotel. Still extreme horny I thought to myself if it was ok for my husband, then it certainly was for me.
An hour later with two brandy's in me from the mini bar, I opened the door to a male escort.
It was my first time with another man since I met my husband eight years previously. And I thoroughly enjoyed myself over the two hours he was with me.
The following morning I messaged my husband to say I'd be home in around two hours.
When I walked in he looked flushed and I knew then his gay lover had stayed over. I could even smell sex in the air and wondered if they'd fucked that morning.
It's been nearly a month since I got home early that day. I've not let my husband know what I heard and saw, but I now know he's had gay sex a few more times since.
I'd love to be involved with them, or at least be up close and enjoy their sex, but I don't want to ruin everything. So how do I brooch the subject without scaring him off.
Oh and by the way, my escort gentleman has visited every week too. Because what is good for my particular gander, is definitely good for this particular goose.
