Your father has already passed away, and you live with your mother and younger sister, Mao. They have spent their days together peacefully, if not amicably. However, Mao, who used to innocently follow you, has grown up to be a bitch who humiliates you whenever she sees you. And in the past few years, her breasts have also grown rapidly, irritating not only your mind but your cock as well. You dream one night that Mao, who looks like a demon with horns, a tail, and a bat, is giving you a titjob and forcing you to ejaculate without any way to stop it. Unaware of this, Mao visits your room and smirks at you, making fun of your attempts to impregnate a trash can with a large amount of tissues in it. One day, while your sister's attitude and big tits are getting on your nerves, your mother tells you about Mao, who has been nodding off at school for the past month or so and increasingly going out after school without telling her where she's going. She asks you to look out for her, but then decides to go away on a business trip. You decide to live a short life together with Mao while paying attention to your mother's wishes. You are grateful to your mother for her kindness and encouragement, but you also feel a sense of shame. But she turns the tables on him and says, “I don't want to be ordered by my brother, who's a fucking ronin!”, this hurt him deeply. Mao goes to sleep one night and only enough her body starts becoming transparent, She suddenly wakes up and immediately falls in love with her brother who is worried about her, but she soon regains her usual mood and begins to order him around. He is immediately put off by this and heads right to his room. When you leave your room, something is amiss. You find that Mao is nowhere to be found in the house. You remember that her body became transparent, you immediately run out of the house frantically searching for her but she is nowhere to be found. You return home anxiously but you eventually fall asleep as if you had fainted. When you wake up, what you see in front of you is the huge ass of a beautiful woman with big tits who calls herself a saint sucking you off. Being a perverted virgin you immediately begin eating her out and eventually end up having sex. Turns out, you are a hero who has been summoned to another world. Your mission is to defeat the Demon Queen. The Demon Queen suddenly appeared and ruled over the demons with her mighty power. She changed the world's official language to Japanese, eliminated studying, and orders cooks around the world to develop and serve her delicious sweets. She also turns all who defy her, human and non-human into cats. Now is the time for a virgin's big dick, which had no use, to become a sex sword to defeat the demon Queen in a different world! [From [official site](http://www.orcsoft.jp/dwf014/story.html)] ## Characters ### Rusuhara Daiki (留須原 大毅) The main character... i.e. you. He is a ronin and NEET who has already failed the university entrance exam twice. He used to be a good boy who excelled in both the literary and military arts, but has become a lazy man due to repeated setbacks. He feels guilty and indebted to his mother, who is kind to him, while his younger sister, Mao, who makes fun of him at every opportunity, hates her 100 times more than he finds her absolutely adorable. He has an inferiority complex toward Mao, but because he is a sincere person with common sense at heart, he tries his best to suppress his desires. He is not well groomed at all, and his long hair hides his eyes with its long bangs. Although he is a large man with a muscular body, he is the type of man that women fear before they think of him as dependable. He used to work out and used to be even more muscular, but now he has a sagging belly and the physique of a Showa-era pro wrestler. Although he is unaware of it because he is a virgin, he has a big dick, and is also very energetic and has a high sex drive.

She is a brash and sassy girl who teases and makes fun of you, her older brother, at every opportunity. When she was a little girl, she used to follow you around, calling out your name. She is a glutton when it comes to sweets, but all that fat goes to her breasts. She is short and petite for her age, but has big boobs that have grown to the point of being ill-suited for her frame. Her face is cute and innocent for her age. Her eyes are narrowed, and she has a sassy and confident look in them. She wears her black hair in twin-tails. When she is summoned to another world as the Demon Queen, she grows horns, a tail, and bat-like wings. While she is the Demon Queen, she becomes the master of the demons and makes unreasonable demands on the countries where humans live, forcing them to make Japanese their official language and to offer sweets to her. Although she is mischievous and thoughtless, she is not excessively vicious and does not take human lives. She hates to lose, and insists that she has not lost yet, even if her body has already given in to cock. But that is also in anticipation of even harder play. She has a tight pussy with a high body temperature and meaty folds with a strong grip. Despite the fact that she is an impertinent girl with huge breasts who says all sorts of mean things to her older brother, she does all this due to her desire for her brother to cruelly dominate her and unveil her masochistic side.

She has the title of “saint,” which indicates that she is an innate user of “sacred magic” that leads to divine power. She is in her late 30s. She is a widow. She is ostensibly a loyal servant of the king, but in reality she is in charge. At first glance, she appears to have a gentle and calm personality, but her true nature is that of a whore, and she is as skilled as a prostitute. She also likes to play the role of a masochist in SM play, but her desire for hard sex is not as strong as her desire to be abused. She has a plump body with big breasts and a huge ass. She wears her blonde hair in an ponytail and wears glasses showcasing her blue eyes. She always has a smiling expression on her face, and her tone of voice is polite and never abusive. She wears a ring on her left finger. During sex, she pretends to be a slave to her man, but this is only to arouse him more, and she actually prefers to take the lead. She has a meltingly soft, yet tightly packed vagina that enraptures any man.
