If my family sees this! Relationship with stepbrother exposed!

My stepbrother and I are preparing for dinner with our family at my house. While I was getting ready, he asked if we should have some fun first. Without thinking too much, I slowly undressed and made myself comfortable on the bed. We got closer and had fun before we started. For a few minutes we forgot about time and enjoyed being together as we became sensually intimate with each other. Our family had to wait a little bit, we were a little late ???? Would you have accepted a delay at that moment?
