"Unleashing the Fruitfulness of My Secret Garden."

The main character, a young man named Jinsang, is at home when he suddenly gets the urge to masturbate. He takes out his penis and starts rubbing it, but soon realizes that he needs some sort of visual stimulation. He searches through his drawers and finds an old porn video tape that he had stashed away years ago. As Jinsang watches the video, he becomes aroused and begins to stroke his penis faster. The video shows a beautiful woman having sex with multiple partners, which only adds to Jinsang's excitement. He continues to masturbate until he reaches a climax, spilling his semen all over the place. Afterwards, Jinsang feels refreshed and decides to take a nap. However, he soon wakes up in a strange room with a group of people watching him. They explain that they are part of an underground hentai video club, and that Jinsang has been selected to star in their next production. Jinsang is initially hesitant, but the prospect of being filmed having sex with multiple partners soon overcomes his reluctance. He begins to perform various sexual acts on the camera, eventually reaching a second climax. Overall, this hentai video description and subsequent rephrase tell the story of Jinsang's sexual awakening and his introduction to the world of underground pornography.
