Miru is my kind, always-smiling older relative and childhood friend, and I have secretly loved her for years. I eagerly await her first trip home in three years, only to discover that city nightlife and dating apps have turned her into a slut who will sleep with almost anyone. “Want your big sis to take your virginity?” she laughs, telling me to pull out my cock. Her transformation shocks me, but this virgin cannot resist when she takes control with that adorable smile.
