"What's going on here?"
"Mom!"
She walked deliberately into her bedroom. There stood her son in front of her dresser, his shorts at his ankles.
"What are you doing?" She tried to use a tone that was a bit sly and coaxing with a touch of maternal authority. She knew exactly what he was doing, and her heart was pounding like a drum.
"Mom, I can't tell you. It's just too..."
She paused and looked at him, her gorgeous specimen of young manhood, back from his second year away at college, robust and fit, and standing half naked in her bedroom.
She tried another tack. "I need to know, sweetheart. Momma just needs to understand. I won't tell anyone. It will be just between the two of us, I promise."
"Can I just go, and we'll forget about it?" He turned to escape out her bedroom door, but she blocked it.
"No, honey, we have to settle this." She closed the door and walked slowly towards him. "Tell me," she said and looked into his eyes.
"I was..."
He was masturbating into her underwear.
When he was home last summer, after his fist year at college, she began finding her dirty laundry disturbed from the way she knew she had left it. The circumstances made her suspect her son who seemed to be without a girlfriend for some time. She was very intrigued and she wanted to know what was going on, so she left a pair of her used panties under a t-shirt but on top of the pile in the laundry basket, and told her son that she would be going shopping and he would be alone in the house for several hours. When she came back that evening she found her panties buried at the bottom of the basket, soaked. The discovery shocked her, but she did nothing, and things continued until he left for school in the fall.
While he was away, the memory of his lust worked on her. Could it be that he really had sexual feelings for his mother? Weren't his hugs and kisses becoming more ardent in the time before he left? Could it be he loved her not just as a mother, but also as a woman? Would he still feel that way when he came back? As the months passed, her love and desire for her son grew.
On his first day back she, once again, deliberately placed her used panties in the laundry basked before she left for work. That night she had come home to find them soaked in his cum. She smelled it, tasted it and was delirious that her boy was back and that he wanted her. She wanted him, too.
