Anonymous Sex Club

I work at sex club as a hostess. I don't need the money, I just like it.
I love anonymous sex behind my husband's back. The club requires everyone to wear a mask, so I've never had anyone recognize me.
However, I've heard some of my clients talking at the bar and realized one of them is my husband's step-brother. I don't know what do you, so I ask the other girls for advice. I tell them my husband hates him for always bullying and taking his stuff.
They reassure me, telling me nobody has ever recognized me and suggest I finish him quickly with a handjob and ruin his night. I agree that would be kind of fun and go for it.
When I get into the VIP room with him, I strip naked and prompt him to touch me : he's touching all the right places and I'm getting distracted from the plan. I tell him to sit down and start stroking his cock. He hasn't brought any condoms, and I use this as an excuse for why we won't be able to fuck tonight... But his cock looks so good and I really want it inside me. The thought of a guy my husband knows and hates touching me is getting me excited. I give in and we fuck and it's amazing.
I then get down on my knees, suck him off a little, and have him cum on my tits. Once he's covered me, he says he expects the same treatment next time he's over for a visit. I'm confused but as soon as he calls me by name, I understand he knew it was me all along.
I'm torn between wanting him to come over and thinking that would be too much.
Anonymous sex is one thing but fucking my husband's step-brother in our own home is way over the line... But I want it sooo bad, and I've already fucked him anyway... So I just tell him to come over for dinner tomorrow.
