In the film, our male protagonist already has a girlfriend. One day, he visits her house, only to discover that his girlfriend is nothing special! His girlfriend's older sister, "Kitano Mina," is the real stunner. Not only is she beautiful, friendly, and talkative, but she's also surprisingly lecherous and incredibly proactive. Wherever they go, Kitano Mina will try every trick in the book to seduce the protagonist when her sister isn't looking!
The male protagonist immediately felt seasick upon seeing this. The three chatted happily, but the male protagonist was actually quite distracted, only thinking about how he could have sex with the sister. His oblivious girlfriend, unaware of anything, got tired after playing around and fell asleep. As the male protagonist helped his girlfriend back to her room and prepared to go to bed himself, the sister suddenly knocked on the door and entered.
He was about to turn off the lights and go to sleep when there was a soft knock on the door. Before he could speak, the door was pushed open, and it was Kitano Mina who opened it. Without any pleasantries or extra expression, she walked in, closed the door, sat down on the edge of the bed, and then the two began to kiss. And that's how it all happened.
After that, the male protagonist would visit his sister whenever he had a spare moment. The two of them would have sex in various places—the living room, the study, the laundry room—and when they got tired, they would lie down on the bed together and sleep, then wake up and continue, until they were completely exhausted and their legs were too weak to stand!
