This is terminology in the swinging community. A soft-swapping couple means only the females do the swapping and only with other females.

"Soft-Swappers" are the majority of swinging couples since, more often than not, the male husband is not bisexual.
"Steve and I love watching our wives fuck. This soft-swapping is a good arrangement since Steve isn't attracted to men at all."
