ai-san and i are not real siblings. when i was a student, mr. ai was the of my father’s remarried partner. a year later, after my parents passed away, ai became my parent. during the days we spent alone, i came to feel a special love for ai-san, who was my only family member. just when i vowed to make ai-san happy in the future, my bad friend shinji approached our family. “your older sister is quite erotic and beautiful.”
