"What happens when you meet a tall and handsome elf king who has saved your life but kill your temper?" ~*~*~*~ "I'm more of a man in this house. Why can't you let me be on top?" Sean asked with a pout. Oswin groaned, rolling his eyes and wondering just how much more innocent Sean could be. "It takes a heavy responsibility to be the top," he replied. "Responsibility? Then it's perfect. I'm making more money, cooking,..." "Sean. I'm talking about things like stretching and penetrating," Oswin explained as he ignored the bulge in his pants. "Do you even have experience?” “Then teach me, your majesty.” “With pleasure.” ~*~*~*~ It all starts when the elf king, Oswin Alvingham, mysteriously gets stuck in the human realm and loses his powers. As he roams the unfamiliar一dirty and low class if he is to describe Earth, he stumbles into Sean Cooper, a fresh graduate, and a full-time table-waiter, who gets bullied in the alley. Though Oswin's magical power is lost, his physical strength remains invincible. When he rescues Sean, the latter decides to take him in as gratitude. And that is where the mess begins. How can the king of the elf cope with his new life? How can Sean convince himself not to be evil enough to kick his savor out of his house? Most importantly, how do an average mortal and the noble upper-class immortal live together under the same roof and on the same bed? ~*~*~*~* P.S: 1) This book contains mature and explicit 18+ scenes. 2) It also contains little graphic violence in some chapters, but I'll put a warning on the top of those chapters. 3) The ELF here is inspired by Lord of The Ring Series. Therefore, they are tall, slender and beautiful. Not tiny little beings like in children fairy tales.]
