Fancy Dress Mishap

I took my husband to a costume party where we pretended to be other people so we could try wife swapping with another couple and after a while we found a couple willing to try it.
All 4 of us kept our costumes on so I got fucked hard by star Lord with mask and he fucked spider gwen. It was only by chance as me and the other woman were getting cleaned up I noticed a tattoo on her wrist as we decided to play with each others cum filled pussys and I realised it was my sister in law.
We left the hotel room after and I haven't said anything to my husband about knowing who they were. Now everytime they visit I can't help but think how his brother in law is a lot smaller than him and how he fucked and creampied his sister.
Should I tell him or his sister or just keep it to myself as a dirty sexy secret?

Was this a masquerade sex party in a venue? Like in Eyes Wide Shut?

It was just a big party in a hotel for staff, former staff, friends family so you had to put your name up for an invite and get it approved.

You should ask hypothetical questions around it to see what he says, the sister too.

Might give you an opportunity for more fun?

You said you and the other woman, now known to be your husband's sister, "decided to play with each others cum filled pussys." Did that include licking the cum out of each other? Or did you find out she was your sister-in-law before you could trade oral?

Do you or your husband have any identifying tattoos or scars that might tip off your sister-in-law that she got fucked by her brother and fingered or eaten by you? If you do, you might consider the advice above and drop a brick sized hint or two that you know she fucked her brother.

Which leads me to one last licentious thought: maybe it wasn't random chance, and your husband and his sister knew from the start who they were fucking and have had a great time since then gloating about getting off with each other right in front of their clueless spouses. We are, after all talking about siblings with many years of hearing each other speak, scream, mumble, grumble, and [if they were lucky] orgasm. Unless they both fucked in absolute silence and didn't converse at all, before, during, or after, they knew exactly who they were getting fucked by. Any suspicions?

I agree with the last part of what Commenter #4 said.
I find it really difficult to believe that brother and sister fucked without knowing it was their sibling.
I don't think it's your dirty sexy secret.
I think it's theirs.
And now that you know your husband is way bigger, you know why.

They've probably been fucking for a long time.
You recognizing her tattoo then she got you off when you two
"played with each other's cum-filled pussies"
makes it pretty clear she wanted you to know.

Why would she do that?
Maybe they want you to join them.
It's her husband who has the little cock.

Who knows?
Maybe you should ask her?
