Unexpected change of clothes in train

Train is almost fully empty and voyeur is sitting across a gorgeous brunette in light summer dress. Normally, he is secretly filming her. When train was reaching the next station, she didn't something unexpected. She changed into a much sexier blue lace dress and matching blue heels. She was discreet while changing clothes but voyeur still caught a glimpse of her tits and her awesome ass in sexy thong. She even put on makeup.
