This would be a man whose wife is bred (impregnated) by another man.
Surrogate mother's husband is a cuckhold for letting another man breed his wife.

Typically done in threesome of two females and one male. The male cums in the first females mouth, who then spits the cum into the other females vagina. Possibly resulting in pregnancy.
At the end of that threesome I became a surrogate mother.
