I caught my brother having sex with our mom

I have been going to college for the past few years here, and this year was my last year. I finally graduated, and I was free (for the most part). But when I got home after graduation was over, no one was around. Not a single sound in the house... that was until I stepped in further, hearing some feint moans coming from my parents' room. My dad wasn't home, so I figured it was probably my mom playing with herself or something.

As I got closer, I could hear the sound of skin clapping. No, she wasn't getting off, she was probably cheating on Dad. I had to investigate, and when I did, I couldn't believe my eyes.

My brother, who is 18, was fucking our own mom right in her bedroom. And he was going at it hard. I couldn't believe my eyes, yet it was so hard to look away. Just the sickness of fucking your own mother really made me uneasy, but at the same time... I was getting a little wet too.
