Yuria Mano, a high school girl, seduces a girl by showing off her underwear (WANZ-291).

My cousin Yulia, who lives in the countryside, came to stay with me for school. She's an incredibly cute girl at high school, but she often shows her underwear at home. She shows it while studying, and even had someone see her having sex with an upperclassman. She shows it while eating… Is it due to carelessness, or is it seduction? It's making me incredibly aroused!!
