JUQ-128 My Beloved Sister-In-Law Who Raised Me Single-handedly Was Taken Down By A Worst Friend... Ai Mukai

Description

Ai-san and I are not real siblings. When I was a student, Mr. Ai was the child 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."
