My wife is pregnant, and we're enjoying a happy time together, but that means our sex life has come to a halt. As a young husband, my sexual desires are hard to suppress, and I struggle daily with this frustration. Then, my wife's older sister, Misa, moves in with us, and being close to her voluptuous body reignites my pent-up desires. Seeing my distressed state, the sister-in-law agrees—just this once—to perform oral sex on me. From that moment on, our relationship takes a new turn.
