25 year old Daon’s dream is to have a beautiful and romantic first sex experience. Then one day she finally found the perfect sized dick that could give her that fantastic experience ; but the problem is….. The man who has the perfect sized dick is none other than her brother’s friend, Na Woo-hyun . Na Woo-hyun is my brother’s friend who has frequently visited our house since childhood. I tried to console myself by saying that I should not have dirty feelings towards my brother’s friend but whenever i closed my eyes the size of Nam woo-hyun’s dick kept coming in my mind. Daon even broke up with her ex-boyfriend because of his small sized dick. At last, Daon could not let go of this opportunity and said , ‘’Oppa, sleep with me just once.’’
