I realized the key to a woman's sexiness was her waistline when I turned thirty. I like breasts and I like asses, but in the end, nothing beats a defined waist. Even if her breasts are a bit small or her ass isn't big, as long as she has a waistline, she just looks irresistibly erotic. On the flip side, no matter how large her breasts or ass are, without a waistline, she just looks like an ordinary pipe. Well, I can still enjoy a "pipe" too, but a woman with a waistline is definitely more attractive. Since then, I've become picky about women's waistlines. Even if a girl has a model-like slender figure, if she lacks a waistline, it's kind of disappointing. This time, An-chan, the girl whose waistline I fell head over heels for, appears in this video. The reason I'm talking so much about waistlines is because she's the ultimate sexy-waisted girl. When she undresses, her perfectly balanced figure and translucent skin are stunning. Her slightly thick pubic hair is incredibly erotic and absolutely perfect. Especially the way her labia rubs against my dick feels unbelievably good. It's not just her waistline—her labia also adds to her ultimate erotic appeal.
