One day, a sudden downpour awakened my strange sexual desire for nipples and underwear that stick together after getting wet... Wet bras, see-through panties, and wet, see-through nipples! The destructive power of see-through underwear clinging tightly to bare skin! Part 1: A delivery girl was caught in a sudden downpour and brought the catering while soaking wet. Feeling sorry for her, I lent her a towel and a hair dryer. Watching her dry off made me feel uneasy... Part 2: I was caught in a sudden downpour while out! I tried to get into my room, but I couldn't find my key. I was worried I would catch a cold if I stayed there, so I boldly asked my neighbors for help, even though I had just moved... Part 3: A student at a private school brought me a good luck charm for passing the exam. However, her dress, caught in the sudden rain, clung to her body in a way that was so erotic it might affect her exam results.
