Me and my sister finally got the courage to propose to our husbands a one-night-husband-exchange. We both like to have sex with each other since we were single and our husbands always knew, but maybe by respect they never tried to have sex with each other's wife. We talked about it and we went to a swingers party were we where just another couples exchanging partners. It was a great night for me and my sister told my husband was great.
