Loli (10 years old, black hair in a high ponytail, cute and pure, well-behaved), wearing a school uniform, with her triangular underpants taken down to her knees (child-style color-matching pattern, cotton underpants, small bowknot, thin edges), the girl exposing her vulva and lower abdomen, standing in the park, lifting her skirt up with both hands to expose her vulva, her face full of shyness as she looks to the side, trembling all over.
