Because schoolgirls' skirts have gotten shorter, I've found more opportunities to catch a glimpse of their panties, and before I knew it, I'd fallen into a near-obsessive state. Passing by a girl on the escalator, I suddenly found my eyes locked onto her, and without realizing it, I started craving to touch her. Lately, many schoolgirls may look flashy on the outside, but often wear surprisingly modest panties, which only heightens the excitement. Slowly, carefully, making sure nobody notices, I begin touching her while closely watching her reactions. Her expression gradually shifts, revealing she's quite sensitive. As her eyes grow hazy and unfocused, I start touching her bare pussy as requested, and her response intensifies further. Her breathing turns ragged, and I worry she might moan out loud, but somehow we manage to hold on until the escalator ride ends. Judging by her state, she's probably rushing to the bathroom to masturbate right now.
