Swingers Parties are usually a private arrangement between a group of friends where they all meet at a private house and enjoy themselves.
Swingers parties are a great way for couples to meet new playmates, as their is usually a good mix of people, so that the chances of both partners finding a playmate to their liking is greatly increased.
The events will usually have between 20 and 100 people, who are all known to the host or arranger.
The organizers will usually charge a nominal fee to cover the cost of refreshments and the clean up crew.
These parties can be anything from an elegant get together with couples slipping off to a bedroom to play, right through to full on orgies.
Group sex is quite often on the menu at house parties, and its a great way for a girl to get herself multiple partners, and for people to experiment with their bi side.
New couples can have same room sex with other couples watching - called soft swinging, or they can be voyeurs and watch others playing.
