On a summer day, I met Risa, a 19-year-old waitress at a family restaurant. Though she doesn't have a boyfriend, she handles her job diligently, speaking in a trendy, modern way while laughing cheerfully. Risa is highly sensitive—no matter what she's touched with, she reacts instantly to various stimulations like vibrators, fingers, and sex. Her intense responses are so overwhelming they leave you breathless. Risa's pure, innocent reactions exude a charm that deeply moves the heart.
