"I have a complex about my inverted nipples," she said without confidence. I've never actually seen an inverted nipple with my own eyes, so I can't say anything about it, but I honestly doubted whether it was a material that would cause me to have a complex. I was like that, but I realized the moment I saw a real depressed nipple. "I was born to meet a depressed nipple." It was such a shock. Why it's buried, why it doesn't show its face, what color the nipple is, it stirs up various imaginations, and I'm obsessed with the inverted nipple. I thought, 'I want to make sure I get an erection'. Originally a hunter race, humans can't help chasing prey that runs away, and on the contrary, their instincts can't be aroused by prey that is standing still. In other words, it is a natural human instinct to want to make a sunken nipple erect. It is no exaggeration to say that I recognized that instinct for the first time. I was going to have sex today, but the purpose has changed. Judging from the results, I think I was able to make them feel it. I think, but the important depressed nipples never got erect. I was so frustrated. I seriously wondered why I didn't have that power. And I made up my mind. Challenge all kinds of depressed nipples all over the country and hone your skills. Wait for the sunken nipples you haven't seen yet! I will definitely free you from that closed world!
