The guy says his older sister got married 2 years ago with a guy that works as a truck driver. They don't have any kids yet and she spends most of her time alone, so when she feels lonely at home she shows up at his place to hangout or simply to have someone to talk to. They started to go out almost every Friday night and come home drunk and this was how things started. For about one month they only where able to have sex if they were drunk but then the guilt went away and his sister revealed herself as a girl that really likes to please her man. He's says he feels pity of her husband.
