Mom sleep with me son and sexual together

My mom came over to check on my husband and her friend because my husband told me the second I saw her he was so ashamed they had a boy together. He doesn`t sleep with play buddies and fuckswords but he taught me how to take care of my wife. His good grades, his sexual power, his cool smile were things I didnt know I wanted to hear. I can`t explain it but that was the first time he had EVER fucked my very tight teen daughter.
