I was invited by a friend to play paintball in Tokyo, and that's when I met Aoi, an incredibly cute military-style girl, and instantly fell for her. Luckily, I ended up on the same team as her. However, being a complete beginner, I was constantly scolded by Aoi due to her bold and assertive personality. During the game, an accident caused me to fall on top of her, and getting turned on in the heat of the moment, I impulsively pinned her down. While Aoi is highly skilled with airsoft guns, she's completely inexperienced when it comes to sex.
