My wife became pregnant, and though we shared the joy of growing our family, it meant I had to endure a dry spell in our sex life. As a young husband, my desires were impossible to suppress, and I suffered nightly frustration. That's when my wife's older sister, Maya, began living with us. The moment I touched my sister-in-law's voluptuous body, my pent-up lust exploded. Seeing how tormented I looked, Maya agreed—just this once—to give me oral pleasure. Her warmth and tenderness brought a new ripple into our marriage.
