SNIS-979 I (the brother) encountered my sister at a sex shop. I thought it would be awkward, but when my sister smiled at me out of the blue, the perverted brothers inside were thrilled by this unexpected development. Shiori Minato

I went to a brothel excitedly, but who came out was my little sister!? My favorite little sister found out I go to brothels, it's embarrassing and awkward as hell! I thought I'd rather die... but then she smiled and touched my crotch! "Big brother wants to do it? Actually, it's not okay...". My little sister, grown up and perverted, seduced me with dirty talk. To have such a heart-pounding development is super lucky!! Even knowing she's my sister, the perverted brothers lose their rationality and commit incest in the chaos!
