DRPT-057 If your pussy is no good, let me lick your anus! My younger brother, who is so worried about a woman's body that he can't concentrate on studying for his entrance exam, begs him to prostrate himself! Monaka Sengoku, a gentle older sister who wakes up as an anal bitch after having her asshole sneeze every day

The younger brother's current problem while studying for entrance exams is that he sees his older sister in a sexual way and is unable to study. When my sister pointed this out to me, I took the plunge and begged her to have sex...and of course she refused. However, her younger brother doesn't give up and suggests, If your pussy doesn't work, let me lick your anus! The older sister had no choice but to accept it, but she gradually became addicted to having her anus licked... without her brother's anal licking.
