Never Seen The Situation Going This Way.

My husband invited Nathan around after the easing of lockdown. He's my husband's new workmate and nineteen years old.
After a few beers my husband told me out of the blue, Nathan has a massive cock. I'm still not sure how he knew, nevertheless he had Nathan show me.
It's enormous and so thick. Ten and a bit inches and nearly seven inches around, I know I've since measured it.
At first I thought it was a prank cock as it was so big. That was until my husband insisted I stroke it.
That continued until Nathan's cock became rock hard, then my semi drunk husband suggested I try to suck it.
Nathan sat right back as I got between his legs, pushed his jeans and boxers right down and I saw his full cock and balls for the first time.
Looking at my husband, he said "Go ahead, I want to see you suck it".
Those were his exact words, so I did.
At first I was apprehensive, but once I kind of got used to its sheer size and thickness, plus wary of my husband being sat right there, I went fully into giving Nathan and his wonderful cock the best blow job I could.
After a short time, my husband said "I told you she was good". And that comment is what made my mind up.
My man, my husband wanted me to have sex with a teenager, so I really went for it. Him saying that comment, meant he'd discussed Nathan having sex with me, prior to that evening.
And sucking his cock wasn't all I was going to settle for. As soon as I knew Nathan was mine, and I mean sexually, emotionally and physically, I quickly removed my knickers, hitched up my skirt and straddled his thighs.
Just as I heard my husband saying something about it Only being a blow job, I guided Nathans cock into my pussy and sank downwards.
The feeling of such a large cock filling and stretching my pussy, had me instantly building to a climax. When he began thrusting upwards, I swear I couldn't hold back the utter joy his cock gave me.
I orgasmed so strongly, I clashed heads with Nathan as my head snapped forwards.
It didn't matter one bit as I heard my husband almost pleading with me to stop. And Nathan did slow down somewhat. But I wanted him, I wanted his huge cock fucking me. And I wanted my husband to watch what He'd started.
Putting Nathans hands onto my breasts, I took full control and made every inch of his cock pleasure me. It was so amazing to have him fill me so wonderfully I almost forgot my husband was there after a few minutes.
He'd stopped asking for us to stop, and when I eventually looked back at him, he was slumped into the chair he was sat on. His face just registered total resignation and I think humiliation.
His whole demeanour had changed and so had mine.
To prove who was leading the night from then on, I got up, leaned over the arm of the sofa and had Nathan fuck me from behind.
His stance had changed too. He no longer cared if my husband was there and entered me with force and told me I was His woman.
I'm not sure if my husband heard him say it, but he didn't refute it, or become angry.
It's the most I'd ever orgasmed in one sexual time. Easily over a dozen times and throughout my husband sat mute. That was until Nathan's cock erupted up my pussy.
My husband cried out "Don't you cum inside her". But it was too late and I found myself telling him " You wanted this".
He's said subsequently I swore when I said it, but I know I didn't.
Completely and utterly turned on still, I moved off Nathans still erect cock, then did something I've never done with my husband. I knelt in front of his colleague and sucked in his cum and my pussy juice coated cock.
It tasted strange, but not unpleasant and I revelled in giving the young man something he too had never experienced.
Feeling his cock throbbing in my mouth, I pulled Nathan on top of me and gripping his cock, had him slide it back into my vagina as I lay on my back.
Literally only inches from where my husband sat, Nathan and I fucked on the rug, and kissed.
In those twenty or so minutes we indulged fully, totally ignoring my husband, I knew our marriage as it was, was totally and irrevocably changed.
Every thrust, every swirl of his tongue over mine, was like a permanent piece of our marriage buried. And I loved it all.
My husband opened the door and the opportunity to his young colleague. I opened my legs, my mind and my sexual self to Nathan and his gorgeous cock.
There's no going back. And to that end I've had Nathan stay over since. And each time my husband either watches and masturbates, or sleeps in our guest bedroom as Nathan fucks his wife.
My husband and I have talked extensively about our new arrangement. And I've told him categorically, if it isn't Nathan, then from now on I'm having other lovers. His response was and is "I'll clean up when they've gone".
