Feeling that bi curosity again !!

Can anyone help out my confusion.

Edit:
[b]Reason for my curiosity[/b]
Around 2.5yrs back I met a couple at bar. We drank a lot and went to their place, I was super drunk and disoriented.
She and I were having 69 and then suddenly she pulled my legs up and he inserted in my ass.

I didn't even realised until a minute later that a cock was in my ass.
She kept me down by sitting on my face and I came by just that in my ass without she even touching me. 🤭
But don't remember the feeling of it and forgot about it until recently. Hell I don't even remember how big he was :(
So want to relive that without alcohol 😉
