The young girl brought her boyfriend to meet her older sister, but little did she know that this would be the opportunity for the boy to have an affair with his future sister-in-law. The young man was always shy and reserved when talking, even when his sister-in-law 'made advances' towards him, he still appeared anxious and fearful. However, in the end, the young man was incredibly lucky to be able to sleep with both his beautiful sister-in-law and his charming girlfriend, as both were very skilled in bed. I wonder how the story of these three will unfold when he gets married?
