FSDSS-727 — My Little Sister Loves Me Too Much And I'm In Trouble, Suzu Nagano

My parents remarried and I had a younger sister called Suzu. I thought we were good friends, but the moment I got a girlfriend, my sister changed completely. Suzu became jealous and showed me her panties, which I love, and tried to seduce me. We were usually good siblings, but I got turned on by her provocation and finally crossed the line.
