The girl she met through an app for finding a casual hookup was Himari-chan, a college student aiming to be a nursery school teacher. She seemed kind, serious, and perfectly ordinary. When she admitted, “I think I’m a masochist,” I slipped a vibrator into her before our date. At the hotel, I played with her, spanked her, went down on her, and pounded her from behind like there was no tomorrow! Her expression was adorable—she was a total masochist I could torment endlessly.
