This is how a mother seduces her son

The boy was in bed doing a crossword puzzle when his mother appeared. At first it seemed like something innocent, maybe even fun. Mother and son playing together in bed. But it wasn’t going to stay as a simple game, and the mother, despite being old, was also a nymphomaniac slut.
After an inopportune word in the crossword puzzle “sex” the mother saw it as a revelation, she had to do it with her son. The boy seemed quite receptive, maybe he had jerked off hundreds of times thinking about his mother, but now he was going to fuck her.
