A Dangerous Kind of Purity

My sister always prided herself on her self-control. Even after six years of dating, she still insisted she was untouched. One day, I noticed something strange–her tongue was covered in metal piercings. That was when I realized… she had been using a different way all along. When I confronted her, she only smirked. "This way, men enjoy it more–and they become obsessed precisely because they can't have me. You wouldn't understand." However, looking at the damage already spreading through her mouth, I could not stay silent. I told her the risks–disease, even cancer–and that men obsessed with that kind of "purity" weren't good people to begin with. She did not listen. That very night, she gave herself to a powerful heir. Later, when the woman he truly loved returned, he discarded her without hesitation. She laughed it off, calling him a scumbag. However, on my birthday, she hid a knife inside a cake–and slammed it into my face. As the blade pierced through me, she burst into laughter. "If you hadn't pushed me to give it away, why would he stop valuing me? Why would he leave me? "This is all your fault. You deserve to die." When I opened my eyes again– I was back to the day I first saw the piercings on her tongue.
