As a single mother working nonstop, I always felt guilty for leaving my son Yuki feeling lonely. However, my son's friend Takashi was always there for us, gradually becoming an irreplaceable presence in our lives. Lately, seeing him—whom I've come to care for like a son—I can no longer suppress my feelings. Every time he stays over, I find myself masturbating by his pillow, indulging in pleasures beyond compare. And tonight again, gazing at his sleeping face, I'm overwhelmed by uncontrollable desire.
