Makoto and Shinobu are my two childhood friends whom I haven't seen in years, but who had always been admired as being the manliest of men, even when they were kids. I, Ryunosuke, am going to be attending a high class school that was once an all girls school, but has slowly started to admit boys. Makoto and Shinobu were already attending there, so the three of us will now be sharing a room together in the school dormitory. I'm looking forward to the start of my rough but manly school life. However, when I get there, it turns out that they are both girls! GIRLS!! I now have to share a room with two people who I, for my entire life, had always thought were boys! They then tell me that it's a secret that they are really girls and that they've been pretending to be boys. Now I will have to help them keep up this rouse. What am I going to do??!! Thus begins the story of Ryunosuke's manly school days which will now be filled with days of plumpness, sexiness, and the maximum amount of naughty slip-ups!!
