Fumino, who works at a library, is actually my sex partner. When we first met through an app, I thought she was plain, wore glasses, and had no sex appeal. But the moment I undressed her, I was shocked by her incredible body and intense libido, discovering her deeply depraved side that craves sex. Our physical chemistry is perfect, and we constantly desire each other. Lately, her fetishes have escalated, seeking increasingly risky acts. Our relationship, driven by mutual craving for excitement, keeps every day thrilling and intense.
