As she loaded her clothes into the washing machine, Lisa saw unmistakable cum stain on her panties. At first she suspected her husband. But she knew it wasn't his style. Then her mind went to her son, Dan. At first she let it go. After all her son is only eighteen and he probably got horny and used her panties without thinking. It won't happen again. But it did. Two more times, she saw cum stains on her panties.
But this time, instead of getting angry for her son's nasty habit, Lisa got excited. At first she thought it was because an eighteen year old kid paying attention for her forty-four year old body. She found herself touching herself as she imagined how Dan was using her panties and realized she was excited because of the idea of her 'son' using her panties to jerk off. She felt sick. But the days go by, she saw more cum stained panties and the sickness she felt went away. She saw Dan was getting more bolder with his little habit. She found her panties going missing and ending up with her laundry.
Lisa wanted to see her son jerking off. So she set it up. Like always she put her clothes in the hamper. But this time she watched her son closely. She saw Dan getting into the laundry room and she followed him. Lisa spied on her son as he jerked off using her panties. She was getting more and more excited. She wanted to do more than watching. She wanted to act out on her fantasies.
"Dan!"
As soon as he heard his mom's voice, he dropped the pair of panties in his hand and turned around.
"What the hell are you doing?" Lisa asked.
"I'm sorry mom... I just..."
"You're just what? Jerking off to my panties?"
"I..."
"Do you have any idea what's your dad going to do to you!?"
"Please mom... please don't tell dad! I won't do it again!"
Lisa was enjoying herself. Seeing her son begging with his rock hard cock hanging out was exciting for her.
"Get out of your clothes."
"What!?"
"You don't want me telling dad do you? Remove your t-shirt and pants!"
