My brother's wife stays up night after night waiting for him to come home late. As she talks with me to ease her loneliness, we gradually fall for each other. We try not to cross the line and agree to share only kisses, but passionate make-out sessions become part of our lives. Then my brother is suddenly transferred, meaning she will move away. Knowing we cannot end with a kiss, I push aside her hesitation and penetrate her. Even fully aware that this affair is a disaster, neither of us can stop the forbidden sex.
