Invited by a friend to a Tokyo-based paintball field, I ended up falling head over heels for Aoi, a military-style girl I met there. She was stunning with a slender, attractive figure, and we became teammates—but she had a bold, strict personality. As a beginner, I kept getting in the way and was constantly scolded. Then, during an accident, I accidentally knocked her down, and overcome with excitement, I pinned her down right then and there despite the ongoing game. She's skilled with an airsoft gun, but when it comes to sex, is she a complete novice?
