My sister Shion from next door has always been unfriendly, cold, and scary, so I'm not very good at her.... However, my parents are good friends, and she agreed to take care of me for a week when my parents went on a trip! Despite her blunt attitude, she spoiled me and lasciviously took care of me! She watches my porn with me, invites me to the SM club where she works part-time, and so on... and then I suddenly realize that she's actually interested in me. Is she actually talking about me? This is a completely subjective experience of living together with a big-breasted, tsundere sister!
