FGAN-155 Because panties make me feel stuffy! My cousin, who goes without underwear, keeps teasing me by flashing her private area, and I can’t help staring!

My cousin, who had been living overseas, came back for the first time in over ten years to take entrance exams, and I ended up letting her stay at my apartment, where I live alone, for a week. Having spent so long in a tropical climate, she was used to going without underwear and said panties felt too stuffy. As a result, she kept teasing me by deliberately flashing under her skirt. When she noticed me sneaking glances, she would playfully tease and provoke me even more.
