There is a clear statement in the kamasutra about threesome. It says 'when a man enjoys two women at the same time, both of whom love him equally, it is called the united congress' and there is an open door for foursome or some more as it also says 'When a man enjoys many women altogether, it is called the congress of a herd of cows'.

Greek myth was made of incest, murder, polygamy and intermarriage in which eroticism and fertility were elemental; sexuality was there right from the start, demonstrating woman’s essential reproductive role in securing the cosmos, extending the human race and ensuring the fecundity of nature.
Also, to the ancient Greeks masturbation was a normal and healthy substitute for other sexual pleasures – a handy ‘safety valve’ against destructive sexual frustration.

There are only few words regarding a congress between one woman and sevral men. In the chapter about the different kind of congress, we can find these lines: 'many young men enjoy a woman that may be married to one of them, either one after the other, or at the same time. Thus one of them holds her, another enjoys her, a third uses her mouth, a fourth holds her middle part, and in this way they go on enjoying her several parts alternately.'
