Tell them to buy a Gigi. They'll understand when they've experienced true pleasure.

Oh, Gigi, you silicone nymph! ::sighs::

We had something like this lol. The key club. Mostly pilots and their wives with a few exceptions. If you were going to be gone you would leave you key in someone elses mailbox who was another member of the club. Automatic green light to come to your house and fuck your wife lol. Still done on a regular basis. A female ( I guess a male could also but never seen it done) can put a box of tide detergent in the front window closest to the front door. Same thing except shes inviting company herself - hubby may or may not be part of the key club. House parties work the same. Girl goes to a bed room. Gets all sexy n ready. Opens the door to the first knock after she is ready and a prospective playtoy will wander in. The catch is a large house with a bunch of rooms and the guys dont get to know which wife is in which room. That way until you get to your own or find yours by accident you and her have no idea of who each are fucking. Also a common party for the ... well oakleaves and above.

0_o up till now I'd never heard of them...though that does explain that little bit in The Grinch where the Grinch's adoptive mommies are having a party and all the other whos are dropping their keys in a big fishbowl.
