"I have a complex about my inverted nipples," she said, sounding unsure. I'd never actually seen them with my own eyes, so I couldn't really say, but I honestly doubted they were worth a complex about. But the moment I saw real inverted nipples, I realized: "I was born to encounter inverted nipples." It was such a shock. They stirred all sorts of imaginations: why they were buried, why they didn't show their faces, what color they were. I became obsessed with them. "I absolutely had to make them erect," I thought. As a hunter-gatherer, humans are naturally driven to chase fleeing prey, but conversely, their instincts are not aroused by prey that stands still. In other words, wanting to make inverted nipples erect is a natural human instinct. It's no exaggeration to say that I recognized this instinct for the first time. I'd been planning on having sex today, but my goal had already changed: to "make them really arouse me and make my inverted nipples erect." If I may say from the results, I think I was able to make her feel it. But the all-important inverted nipple never got erect. I was very frustrated. I seriously wondered why I didn't have that ability. And then I made a decision. I would challenge every inverted nipple in the country and hone my skills. Just wait, you've yet to see an inverted nipple! I will definitely free you from that closed world!
