Women's uniform skirts are shorter! It is full of the schoolgirl of the mini length which ascends the staircase. I think that the skirt of the uniform is short though it is a girl school walking in the town. It is the only existence that chases by the eye. It is a situation that a short schoolgirl of the skirt length goes up the stairs in front of me, and it becomes exciting if my position is good. However, a healthy society person is actually not able to look at cancer at such time. I feel embarrassed when I see myself who is looking at me. I feel like I'm going to step up stairs quickly while I'm thinking... All right! If you are a staircase girl, I will show you the actual state of the secret of the schoolgirl who has stepped up stairs.
