The best way to fuck other women on the side without ending up in divorce court or in the wraths of a pissed off girlfriend. This can broaden the sexual horizons for any couple by providing the male with the opportunity to get some new pussy occasionally and helps the woman live out her secret, curious masterbation fantasy.
That dude is lucky. He had a big threesome last night. His girlfriend's co-worker rode his cock while his girlfriend sat on his face and rode it like the Kentucky Derby.

Get the threesome mug.
The act of three people having sex simultaneously.

A fantasy for most men because it is NEVER going to happen.

If it did,they probably would be left out because the two girls would forget he was there.
Forget the threesome. It is the male equivolent of Big Foot.

You have heard about it, seen madeup footage of it, but it does not exist in the real world.

A threesome is a form of sex that is the third level on the ladder of sex (2 people = secs, 3 = threesome, 4 = smash, 5 = mass orgy, 6 = shrekfest). Threesomes are not very famous as it doesn't have the amazing feeling like secs or the fun like smash or shrekfest. It is not considered one of the main forms of sex, that's why people refer to it as a "secondary form." However, another type of a threesome is called a "Gleesome Threesome," which is much more famous and common as it involves the use of Dildos and Blow jobs.
Person A: "Wanna have a Threesome?"
Person B: "Is it a Gleesome Threesome?"
Person A: "It can be if you want."
Person B: "Good"
