I found Mikoto, a first-year university student, at a track and field meet. She's a substitute. She's not a regular, but I cheer for her because she's hardworking and cute. I got to know her as I went to cheer her on at every meet. I gave her new shoes and training clothes, and I was able to tame her. Today I'm going to practice with Mikoto at a hotel. I'm hoping she'll sweat a lot and show me her naughty panties...
