The siblings had grown up together, sharing everything. But as they matured, the girl began to notice her brother staring at her inappropriately. One day, after catching him red-handed, she decided to confront him.
"I saw what you were doing, perv," she spat out, her eyes narrowing menacingly. "You've been watching me change for years."
Her brother's face flushed with embarrassment and shame. "I-I can't help it," he stuttered, his gaze fixed on the floor. "You're so hot, sis."
The girl smirked, taking a step closer. "You know what? I think I'm going to use this against you. I'm going to tell dad that you were perving on me."
His eyes widened in horror. "No, please, I can't bear to see you like this."
