I witnessed my mother-in-law getting fucked and covered in sperm

I can't believe what I just witnessed. My mother-in-law, who I thought was as innocent as they come, getting her fat, hairy ass pounded and covered in cum. It was the most shocking thing I've ever seen. I didn't know what to do, but I couldn't tear my eyes away from the sight. She was getting fucked like a whore, her big, fat ass bouncing with every thrust. The sight of her being taken from behind was too much to handle. The guy was fucking her hard and fast, his big cock stretching her tight hole to its limits. He was drilling her so hard, I could hear the sound of skin slapping against skin. The sight of her getting covered in cum was something else. It was all over her big, fat ass, making it even more enticing. I couldn't believe my eyes. This was definitely not the kind of family fun I was expecting.
