At the ticket gate, I spotted a petite, attentive office lady type walking around. As I noticed her heading toward the platform, I became curious about what kind of underwear she was wearing and decided to board the same train. Her backside was smaller than expected, yet her shapely figure was clearly visible even through her skirt. Gently brushing against her without being noticed, I could see her gradually responding. A subtly sensual and alluring atmosphere begins to unfold between us.
