[WARNING THIS NOVEL IS A SEX NOVEL WHICH INCLUDES SEX CONTENT][Author Note: I have changed the story entirely]Arthur's head hurt like crazy as he woke up. He kept his eyes closed, rubbing his temples and feeling a super comfy bed under him - definitely not his cheap mattress back home.“What the hell...?” he mumbled as he finally looked around.He was in some rich person's bedroom with a fancy four-poster bed and red silk sheets. Sunlight came through pretty stained glass windows, making red patterns on the marble floor.Everything screamed royalty - fancy mirrors, portraits of hunting scenes, and even a painting of a barely-dressed goddess that seemed to be watching him.“How did I get here?” Arthur wondered, getting out of bed. “I definitely drank too much at Mark's party last night”The last thing he remembered was almost getting hit by a car while crossing the street.Looking in a mirror, he got another shock. He didn't look like himself at all! Instead of being skinny with acne scars, he now had muscles, clear skin with just one cool scar on his jaw, with a reddish brown hair, and green eyes.“Damn, I'm hot,” he said, touching the scar.For a moment, he remembered his old life. He pushed up his glasses. Kids made fun of him. Jessica laughed at him when he asked her out. “Like I'd be with a loser like you,” she told him.Suddenly Arthur realized what was happening. “I've been transported to another world! Just like in those stories online!”He spun around excitedly. “I must be someone important here. This is gonna be so cool!
