Mother in law discovers inappropriate images on her stepson's computer

When the young guy was away at work, his MIL decided to snoop around on his computer. What she found there left her utterly shocked and appalled. The computer was filled with inappropriate pictures and videos that were far from family-friendly. It turned out that our naughty boy had a thing for some rather taboo content featuring his mommy. The MIL, being a good woman, knew she had to have a talk with her stepson as soon as he got back. But something strange happened. The more she looked at those images, the more aroused she got. It was like a forbidden fruit that tasted so sweet. She couldn't help but crave for more. When her stepson came back, she confronted him, but instead of being mad, she found herself in the middle of the most erotic encounter of her life.
