DVRT-009-Uncensored-Leaked — The switch that turns a bad older sister into a masochistic sow - Ninomiya Waka

My older sister, who was notorious as a bad girl in our town, had a switch that would turn her into a masochistic slut. Since she had always treated me like a slave, I decided to r** her when she transformed into a masochistic slut! But... I had no idea she would revert back to normal, so all I could do was pray to God (crying).
