Every summer, when I go back to my hometown, I stop by my relatives' house to say hello. When I enter the front door of the country house, which is unlocked, and say "I'm back," my cousin Natsumi comes down from the second floor and glances at me while drinking barley tea from the refrigerator, saying "Oh, welcome back." Every year, when I come back, I feel embarrassed at first because it's been so long, but before I know it, I'm back to normal. I think she's a brat who doesn't like to be with her friends, but that's what makes her cute. And what surprised me was that her breasts have grown incredibly big, even though I thought they were still growing! When she came down the stairs, they were bouncing! My cousin has developed into a female body so much that I don't know where to look, and she makes her erotic body defenseless. Every year, we always get along and play around, and we always end up feeling a little naughty and getting each other horny, but this year, I definitely want to do it! ...And I did it. A personal video of my cousin's voluptuous, horny body, her growing breasts, and her loli-lined, shaved pussy having creampie sex during summer vacation. Please enjoy.
