与他的妻子和他的年长的继妹一起发生性关系

The elder stepsister was very sad due to her divorce from her husband. One day when she went to her younger stepsister's house, she told her younger stepsister to share your husband with me. The younger stepsister was shocked at first, but later with the condition that "I will give you my husband only once," the younger stepsister shared her husband to the elder stepsister.
