The XC-Club is a swingers club on the Bahnhofstraße in Erftstadt-Liblar, west of Cologne. It runs on a party calendar rather than fixed opening hours: an after-work night on Tuesdays it calls Afterwork XCitement, a Friday weekend party, and a Saturday party — with named one-offs threaded through them, from an FKK swinger party and a couples' Sunday afternoon to a gang bang day run in two sittings and a golden shower night.

Regulars and new faces are equally welcome, in the club's own words. Registration for the parties runs through JOYclub, and the club can also be hired out whole.
