I came home from college on Thursday instead of Friday like I said so I could suprize everyone. But I caught my mom and stepsister in bed together. They were both totally naked and asleep on each other. It was obvious what they had been doing. The evidence was clear. I just left and went to my boyfriends house. I called as if I had not been there. They do not know that I know. I am a bit upset about it. My mom just got remarried and I was just starting to get to know Becca. I don’t know what to say or do. Maybe they will just tell me. Or should I confront them? What do I do? It is all I can think about.
