One day, a very serious and timid girl sitting in front of my seat suddenly wore flashy underwear that was so transparent that it was visible through her white blouse! As I was staring at it, I couldn't help but get an erection even though I was in class! ! When I couldn't hold back anymore, I pretended it was a coincidence and touched her butt lightly, but she reacted more sensitively than I expected!

Usually the white bra lines just show through, but today they are so clear and flashy! Is that serious girl wearing flashy underwear? Just thinking about that gap makes my lower body tingle! I can't hold back anymore, so I secretly touch her butt from the back seat! Then, she suddenly starts fidgeting and makes an erotic face...
