A woman likes flashing her panties and pussy at men to get them excited. She decides to show off on a train, but draws the attention of a young woman and ends up having some dirty female fun.
Excerpt: She leaned back on the seat and slid her ass forward a little, feeling the skirt ride up her legs. Katherine let the skirt ride up just enough to bring the stocking tops into view. She glanced quickly at the young woman and saw her watching intently. Katherine rested her head back on the seat and closed her eyes. Over the next few minutes she let her knees slowly part. She was sure the young woman would be able to see her thong and could feel herself getting wet as her excitement started to kick in.
