HUNTA-277 Forced to participate in a “SEX study session” hosted by a woman who just wants to eat virgins? After enrolling in university, I decided to live with my sister who resides in the city. Then, every weekend, she gathers her friends and makes a hug

A younger brother who went to a university in the city decided to live with his older sister who moved to Tokyo. However, her older sister is a ridiculous bimbo, and on weekends, she makes a big fuss with her female friends and erotic stories! When the younger brother who was dragged into the circle finds out that he is a virgin, he calls it a SEX study session and begins a writing experience! I don’t want to lose my irreplaceable first experience with something like this! But I can’t stop the piston from the comfort of my first SEX! After all, all the bimbo begged for Ji ○ port and ejaculated all night long!
