HUNTA-863 For three days while my parents were on a trip, my older sister, who is a serious class representative, was forced to sleep and fucked by the bully's orders.

My older sister is a very serious student who works as a class representative and is a typical honor student both in appearance and inside. But I was ordered by a bullied girl to put my sister to sleep using sleeping pills. Then, on the first day, my sister was raped by the bullies while she was asleep. On the second day, my sister starts to feel it when I continue to fuck her even though she doesn't like it. By the third day, my sister had transformed into an outrageous dick-crazy who asked for it herself.
