Bro, speaking of watching porn on the phone, it's one of my habits when I wait for my girl.
One time I was waiting in a massage room so I whipped out my phone to watch some porn vids I had saved in my cloud drive. Lo and behold, I must've cranked up the volume to max earlier on doing some shit, the video started with the loudest sound of a girl moaning! I went "oh shit!" and quickly muted the video, then I heard the ML next door giggling with her customer at my expense!
