While doing yoga poses, there are moments when you unexpectedly feel aroused. As you sweat, the inside of your leggings and armpits become damp, and as your body warms up, moisture starts building in your underwear. At times like these, you can't help but playfully tease your sexy ass during yoga. Mizuki gets wet in her underwear with an arousal that's different from sweat, creating an unpleasant dampness that somehow feels incredibly erotic.
