When did you start getting interested in thebuttcrack of female

The first time I ever saw a woman's butt crack was in 2011，when I was 12 years old. One day, while eating at KFC after school, I noticed a woman who looks like thirties had come in with her child; she was wearing a white top and blue jeans. She was slightly heavy-set, with a large, round, and shapely ass. In a stroke of incredible luck, she sat right next to me. Half of her butt and her black underwear were exposed, it was something I had never seen before. She seemed aware that she exposed her big ass; she kept standing up to pull down her top or struggling to hitch up her pants, but to no avail—her jeans simply couldn't contain her large ass. It was a truly unforgettable experience for me, and from that moment on, I began to take notice whenever a woman's butt crack was exposed.
