My dad fucked my best friend and I found the video online

I was scrolling through some sketchy links on Tinder when I saw it—my best friend, that hot chick, bent over, riding my dad’s big dick like she owned it. Doggystyle, sweat glistening, moaning his name. She knew who he was. She grinned at the camera like she’d been paid. I didn’t delete it. I rewound it. Again. And again.
