staircase school girls, when i see inside the uniform skirt, i feel like an erotic punchra

When a girl school student falls down the stairs, she is just in front of her eyes. It's a clunky thing that all of us are moving in front of our eyes. Isn't it best if you see the underwear even in a flicker there? The best thing about being more erotic is that if the seen underwear is sexy, ingested, transparent or T-back, you'll never be able to think of it! what's that mean? she's a staircase schoolgirl.
