I'm Fucking My Best Friend's Stepmom

My best friend invited me to his house. His stepmother invited us for snacks while we played Xbox. I decided to go to the bathroom, but when I got there, I saw a room. The door was slightly open, and I could see his stepmother half-naked. She noticed me and invited me in. She started giving me oral sex and then asked me to have sex with her. But my best friend found us! He wasn't prepared for what happened next. We started having sex together, my friend and I fucking his stepmother. She was satisfied, her breasts full of cum. But something strange was happening. Was it all a dream?
