Cheating For Two

My wife Erica has been cheating on me with a coworker of hers.
What she doesn't know, is since I found out, I've been fucking both her son and daughter.

It was actually her daughter who told me to check out a car park they often have sex at.
So I did. And yes my wife was bouncing up and down on her colleagues dick.

Back at home, Becky asked me if she was right. When I nodded, my step daughter simply said "OK, let's fuck".
We did. We had sex in her room, then in the shower where she had me fuck her ass. I swear, I'd never been so turned on.

When my wife got home later on, she had my step son Andy with her. He's older than Becky and had been at college.
I'm not overly sure what the siblings said to each other, but when I was fucking Becky in her room again the following day, Andy walked in.

He made out it was a total shock to him, but now I know they'd arranged he'd catch us.
It was a bit of a charade with him feining disgust and anger, but I knew the gay twenty year old wasn't staring at my cock for nothing.

It was Becky who told me to discuss what I knew about his mom, in his room.
When she entered only ten minutes later, her older brother was giving me oral sex.

Becky left us to it, but not before saying to Andy "We share everything, right!". A few minutes later I busted my nut down his throat.

And that's been the case for ten amazing months.
Some days I'm balls deep up a beautifully tight young pussy. Other days I'm fucking a very willing gay ass.

I'd love to get them both together and possibly record us having sex, but Becky says she's not into that kind of sex.
She's into everything else though.

As for Andy, I only fuck him when he's home from college. We do have great sex, really rough sex sometimes. But he's not as sexually active as his younger sister.

You might ask why my wife cheats on me. It's because it's in her nature. I'm her third husband.
