This started as a joke but her husband took it serious. She told him she would like to have a gang bang and even told him with whom she would like to have it. She said she wanted it with four guys, her husband, two of his friends and a fourth person she didn't told him right away who he was. Only after her husband told him he was planning the gang bang she told him who the fourth guy was. It was her brother. Her husband wasn't surprised, he was already suspicious he might be him.
