His Colleague, My New Lover

My husband came home from his company Christmas party with an older male colleague a fortnight ago.
They had a drink talking about this and that, then my husband tells me out of nowhere, Mike has a really big cock.
Before I know it, Mike is stood in front of me with the biggest dick I've ever seen. My husband practically orders me to suck it, so I did.
After a few minutes I heard my husband say "That's enough". But by then both Mike and I didn't want to stop.
My husband says it again, only a little more forcefully, to which Mike tells my husband to "Shut the fuck up, you wanted this".
By this time my pussy is aching for his huge cock and I decided to see how it'd feel deep inside me.
Removing my skirt and knickers I knelt up on the sofa and Mike got behind me.
The feeling of his large length filling me was so good, so strong, I climaxed immediately.
And for the next ten minutes or so as he fucked me so deep, I orgasmed over and over again.
My husband was angry when Mike came in me and then pulled out, but he wouldn't say anything further to Mike.
When Mike left in a taxi, my husband tried to shout at me, but I reminded him it was he who brought his colleague home. And it was he who wanted me to suck Mike's dick.
In the last two weeks I've met Mike several times and we've had sex in each others cars. He wouldn't have been someone who I'd normally go for, but he's a great lover and his cock is utterly beautiful.
