True story.

My mom remarried when I was 7. A day or so later I couldn't sleep and wandered into her bedroom like I always did before. I froze when I saw her and my step-dad naked and fucking on the bed. It was dark but the street light from outside lit them pretty well.

I can still picture it, too. Her eyes were closed and he was sucking on a breast while he fucked her. I didn't know what to do. I was mesmerized by the weird show.

My mom opened her eyes and spotted me. Instead of freaking out, she just calmly asked what was wrong. My step-dad looked at me and let out a frustrated sigh. he mumbled something about locking the door next time.

He pulled away from her and lay back. My eyes were drawn to his erection sticking straight up and still wet from my mom.

My mom touched my arm and asked what I needed. I said I was thirsty. She got up and walked to the kitchen, still naked, then got me some water. Then I went to bed and she went to her room closing the door.

Only time I ever caught them.
