I married my former coworker and left my job to start a family, but I carried a secret I could never tell anyone—that my ex-boss, Mr. Matsuda, had once been my sex slave. I thought our connection had ended when he was transferred overseas, but it turned out I was the only one who believed that. After returning to Japan, he resumed working as my husband's superior and soon began visiting our home without hesitation. He tightly bound my body with hemp rope, and helplessly, I was flooded with memories of past pleasures. Obedient to his commands, I surrendered myself to the sensation of the ropes, took his rock-hard cock deep into my mouth, and climaxed intensely. His dominant demeanor and the overwhelming pleasure he gave my body reignited old memories and awakened new desires within me.
