ADN-351 Weekend only, couple swap, night when my wife is embraced by someone else

My husband came home with a gloomy expression on his face. - I made a terrible mistake at work. - This is the first time I've seen my husband so depressed... Then, something unbelievable came out of his mouth. - "Would you please do a husband and wife swap?" - My husband and I had no choice but to accept his partner's proposal to make up for the mistake he had made.
