"If your pussy is no good, let me lick your anus!" My younger brother, who is so worried about the woman's body that he can't concentrate on studying for his entrance exam, begs him to kneel on the ground! 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 her sister pointed this out to her, she took the plunge and begged her for 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 reluctantly accepts, but she gradually becomes addicted to having her anus licked... her body can't stand it without her brother's anus licked!
