My brother, who's a ronin student, spends all his time shuttling between cram school and home. With no girlfriend in sight, he keeps jerking off constantly. One day, I caught him masturbating while secretly watching me, fantasizing about having sex with me. That's when he confessed, "To be honest, I've always had feelings for you—I couldn't focus on studying at all." Does big bro really depend on me? I want to understand his feelings even more.
