Recently, dating apps have been gaining popularity, and I've been using one occasionally during my work breaks. One day, between jobs, I chatted someone up, successfully lured her out, and arranged to meet the next morning at a nearby station. The girl who showed up was Chiharu, a cute, smiling young lady with a refined, well-mannered demeanor. At school, she was treated as a top student and even served as class president. Raised strictly under her parents' rules, she had a curfew and lived a tightly controlled life. In order to meet everyone's expectations, she had long been pushing herself, pretending to be someone she wasn't. Just listening to her story made my shoulders tense from the strain. When she entered high school, she grew exhausted from that lifestyle, and at a friend's suggestion, tried using a dating app. That's when she discovered a completely new world unlike anything before. Her rationality crumbled, and she awakened to lustful desires. Since then, whenever she has free time, she checks the site and has become deeply addicted to paid sexual encounters. Her way of relieving stress is having rough sex with older men. This time, having chosen me, she agreed to cooperate in filming in exchange for certain conditions. When it comes to masturbation, especially as her period approaches, if I ask her to demonstrate, she honestly brings her hands to her breasts and crotch, touching herself shyly. Close-ups of her face while making her speak lewd words, or moving her mouth in a dirty, suggestive way—she fulfills every request without a single look of discomfort. Her gestures and attitude are incredibly alluring. When she shows me her panties, they're remarkably neat and clean, perfectly reflecting her charm.
