HUNTA-739 Thanks to my sister, who is incredibly popular in our all-girls school, I do lewd things every day with a younger student who admires her. My sister from the prestigious girls' school is called 'Onee-sama' by the underclassman...

My older sister, who goes to a girls' school, is adored by her juniors and is called "onee-sama", but at home, her hikikomori brother obeys her! My Older Sister, Who Can't Resist Because She Has All-you-can-eat Creampie Sex Every Day, Can't Resist Her Brother's Demands, "I Want To Fuck Another Woman!" And a rich kiss and put the junior girl in a state of obedience. A junior girl who is fascinated by her sister's confession is sacrificed to her brother who has become a sex animal! I'm going to have sex with a lot of resistance in vain!
