SDMF-044 At home, I make my younger sister wear a school swimsuit so that I can slide her inside her at any time. ~An undeveloped body that doesn't know men falls in love with her brother's twisted love~ Kirari Kaede

That was my second year. I don't know what happened at school, but my brother doesn't leave his house anymore... "Onii-chan...I know that you have my school swimsuit..." Anyway, I want to cheer up my brother. With all my heart, something happened that was a secret to my father and mother...Maybe it was me who changed, not my brother.
