Estoy siendo follada duro por un amigo mientras estoy en el teléfono con mi esposo

My husband is very jealous and he often calls to see how I'm doing. This time he called at a very bad time. I fucked his best friend. I had to get out of this situation. His friend has such a big dick. He hammered me so hard, I got all wet. In the end, he came in my beautiful panties. How do I explain to my husband how I got cum on my panties?
