A form of group sex that specifically consists of 1 man and 2 women. Ideally, the ladies involved should be bisexual and interact sexually with each other to some degree but this is not required. The two women may be completely hetero and have no contact or interaction with each other. Either way, the focus of attention is generally on the man. Any normal man who is legitimately attracted to women and finds himself blessed with such a spectacular bounty of female unicorns would NEVER decline to participate under either set of circumstances.

Note: A king's threesome will provide a splendid opportunity for the participants to perform a variation of an "Eiffel Tower". This is highly recommended and encouraged. Whether it's the two ladies or one of the ladies and the guy who high five each other and regardless of the sexual position or configuration, the Eiffel Tower is certain to produce a cute little smile and / or giggle from one or both of the ladies and a rush of gratification and ego boost for the man.
