For some reason, my older sister is cleaning the house in a sexy outfit. I thought I saw a panty flash, so I peeked closely—only to find she's actually flashing her pussy. Such a chance rarely comes by, so I can't help but stare, my cock instantly hardening. Then, as if noticing me, my sister smiles and continues exposing herself without a care. Her boldness only turns me on more. "Don't just stand there with your dick hard," she says, beckoning me closer. Intrigued, I move toward her, face-to-face with her erect nipples and wet bare pussy, completely drawn in by her provocative attitude.
