You're getting your butt fucked and your partner farts and you stick your tongue in their ass like a key and you do it twice to open the door for more fun
He farted while I was getting butt-fucked, so I stuck my tongue up his ass like it was a key and I did it twice to open the door for more fun.
I was getting butt-fucked and he let out a fart, so I stuck my tongue up his ass twice like it was opening a door to the best part.
He farted mid-fuck and I stuck my tongue up his ass twice like I was unlocking the secret door to more butt-fuck heaven.
