It had already been twelve years since I began living with my nephew Kyosuke after the passing of his parents. My husband and I, unable to have children of our own, had raised Kyosuke as if he were our very own son. However, he didn't see me merely as a mother figure—he desired me as a woman. One night, he sneaked into our bedroom while we slept, crept up beside my slumbering husband, and began to claim my body. Desperately suppressing my moans, clenching my teeth, I was repeatedly brought to orgasm by his young, vigorous body. Though my mind resisted, my body burned with heat, trembling with forbidden emotions.
