She smells sooo goood

It began when I was young . My older niece stayed over for a week or so. We were playing outside when I had to use the restroom so I when inside. I don’t quite remember how I got into her back pack that was in my sisters closet but I I did and locked the door to sniff her panties. She comes knocking on the door and I quickly put them back and opened the door. She asked me if I was smelling her panties and I acted like I don’t know what she was talking about. Til this day o don’t know what she thinks happened.
