What did my best friend mean by this

My female best friend and I were in a cafe and were talking about taking sunset pics and we started clicking pictures. She never hands me her phone but this time she handed me her phone and specifically asked me to keep scrolling for more sunset photos and then BAM

I suddenly saw her nudes and I immediately gave her phone back to her, it was so fast she didn’t see that I saw her bare pussy. Never has my heart beaten that fast in my life. Phew.
