Cuckolds New Life

When we first met, dated and even at the beginning of our marriage, I was able to keep up with, and satisfy my wifes sexual needs.
She's simply put, a nymphomaniac.
She's twenty nine, slim, a brunette, pretty with average sized breasts.
Before we got together and this is something I've only recently found out, my wife would attend sex parties, often being the central attention of older men fucking her.
Just over a year after we married, I came home early from a business trip and found my wife in our lounge being fucked by two older men (50's).
She was sitting on one of the guys cock, as the other was fucking her arsehole from behind. My wife was obviously enjoying the sex and I even heard her orgasm as I stood in the doorway.
When they eventually noticed me, my wife told the men not to stop. So they carried on fucking her. She then told me to get them all a drink, and to bring them naked.
I'd never heard her talk to me that way, nevertheless I got the drinks and walked back into our lounge naked and fully erect.
Fifteen or so minutes later, with my wife lay on our leather sofa and both men having cum inside of her, I plunged my cock into her soaking wet c**t.
I didn't last too long and came adding my cum to theirs. And that's when my wife truly introduced me to my new role in our marriage.
Over the next ten minutes as the two older men drank the beers I'd gotten them, my wife had me devour her pussy, clit and arsehole.
I've always enjoyed giving my wife cunnilingus, but had only ever eaten out my own cum from her love holes.
Eating out the other mens semen, was new to me, but I did it to please my wife, who orgasmed twice whilst I gave her oral sex.
Once she was satisfied, my wife had me sit on the couch and hold her. One of the guys had become erect again and she had him fuck her as I held my wife and played with her breasts. He fucked her hard and fast, cumming after only a few minutes.
Once he'd cum, my wife and I went upstairs to shower, but not before my wife kissed both men goodbye. They were gone when we came back downstairs and it was then we talked about what had just taken place.
Apparently she'd been having sex with both men separately for a couple of months. I'd entered our home that day, when she'd invited them both round for the first time.
That first threesome they had, was eight months ago. Since then they've visited our home together several times, with the older of the two, Mike, fucking my wife almost daily during the weekdays, when I'm at work.
There has been a development however with myself and the second guy. He's called Stuart and as I found out during one of our get togethers, he likes me sucking his dick.
I didn't want to at first, but my wife insisted and I found not only did I enjoy it, I also discovered I'm better at sucking cock than my wife is.
Well recently I've also discovered I love being fucked too. Stuart is divorced and lives in a flat only half a mile from where we live.
He and I have been having gay sex once or twice a week at his flat, and each time he's fucked me. I now know he much prefers guys and originally wanted to fuck our other male sex partner. But he wasn't into guys sexually.
We all still get together each week for sex and I love the diversity of our liaisons, yet I'm definitely enjoying the sex with Stuart far more.
My wife and I are not going to split up or anything, but I'm also not going to stop exploring my gay sexual enjoyments either.
It's a door my wife opened up for me, and I've welcomed stepping through it.
