A couples party where all of the men put their car keys into a bowl or bag and at the end of the party, the women blindly select a set of keys to determine who she goes home with for the rest of the evening for sexual gratification.
Last night I got to take Jerry's wife Sue home from the key party for the first time. She gave me a better blow job than my own wife Jan, but I love her more than anything, especially since she likes to attend the key parties with me. Jan went home with Bill and said she liked how large his penis was, but that I still make better love to her than any of her other partners.

I took Bill's wife home from the key party last night. My wife could take lessons from that righteous bitch!

When at a party/gathering, all the men place their key rings into a bowl. Next, each woman takes a turn and grabs a key ring at random. Which ever ring she pulls, is the man she sleeps with.
