I'd say that would mostly depend on how things went between the two couples. If everything goes well then the only after effect would probably be a closer relationship. If things don't go well for one couple or the other, it could cause a rift, especially if the two couples were friends before they played together.
If the two couples just meet and go at it, and one or the other decides they aren't interested, what I've seen more often than not is that the uninterested couple just stops communicating, no longer emailing/ calling or returning calls/ emails.
