Honestly Didn't Know

For eight months I've been fucking a female colleague from work.
She's in her mid thirties and believe me, she's a real dirty bitch.

There is nothing we don't do, either at work or at my flat.
Before we began having sex I knew she was married, but told me her older husband wasn't horny enough for her.
And I can believe that.

She sucks my cock, rims my arsehole, has me tonguing her pussy and arsehole, then fucking her pussy and arsehole too.

We use sex toys as well. With me fucking one of her fuck holes, as she uses one of the dildos to fuck the other.
Pussy and arse to mouth, she just doesn't care and these past few weeks she's had me fist her arsehole.
She's by far the dirtiest bitch I've ever had sex with, and we fuck a lot.

Sometimes we can sex three or four times in a day. Often having quick but intense fucks at work.
After one of those fucks a few weeks ago, another female colleague who I get on with, told me when she saw us all flushed coming out of a store office after sex "You do know she's the bosses wife".

Not once in all the time we've been having sex has she hinted the boss is her husband. I honestly didn't know.

The thing is, now that I do know, fucking her in as many horny ways and places is all the more amazing.
