Despite thinking it's wrong to cross the line, the impulse to take advantage of my sister, who is wearing a school swimsuit and has enormous breasts, was overwhelming. My brother, a school swimsuit fanatic, targets her overly developed, youthful body! While our parents were away on a trip, leaving the house empty for a few days, my brother was secretly filming my sister, but just watching wasn't enough, and eventually... he used my innocent, pure sister in a school swimsuit as an outlet for his sexual desires. At first, my sister resisted, but she gradually became addicted to the pleasure of sex while wearing a school swimsuit. A detailed account of the incestuous acts between my busty sister and perverted brother within our home!
