As a single mother, I've been so consumed by work ever since my son Takaki was young that I may have left him feeling deeply lonely. But having his childhood friend Hirokun around, always there for us, helped ease the burden. He became like family. Lately, though, I've started feeling an unexpected attraction toward him. Every time he stays over, I find myself overcome with the urge to masturbate beside his pillow. And tonight, once again, I catch myself gazing at his sleeping face, yearning intensely for pleasure from the bottom of my heart.
