Six months ago, my older brother got married and his wife moved into our home. She's the same age as me, cheerful, friendly, and doing her best as a housewife. But one day, I found a sexy piece of her lingerie among the laundry. From that moment on, I started masturbating every day, fantasizing about her. Then one day, her secret was finally revealed—and the truth was far beyond anything I could have imagined.
