Contra Dancing is a form of American folk dance in which the dancers form a set of two parallel lines which run the length of the hall. Each dance consists of a sequence of moves that ends with couples having progressed one position up or down the set. As the sequence is repeated, a couple will eventually dance with every other couple in the set. Contra Dancing was all the rage in 1800.

Contra Dancing is an ancient Japanese art-form. Basically, there are these one or two girls who stand naked in the middle of the room. Then these guys get naked and stand in the circle around them. Now it becomes truly artistic as the possibilities are endless. Somehow the men are brought to a climax either through oral sex, anal stimulation, direct coital contact, or masturbation. The men must restrain themselves though and the last of them is ready to orgasm. Then all of the men, often in numbers above 10, ejaculate their fresh baby batter on these girls' beautiful faces. The girls really love it and I know you will too.
