Mom fucks her stepson while her husband rests

Like so many other times her husband came in, ate dinner, took a nice bath and locked himself in his room, and just as after so many nights she went to her stepson's room, the boy had grown so much in the last year that only she knew how to take advantage of it. It had started with little flirtations, innocent jokes and little carelessness of her showing herself naked, until the boy could not take it anymore and confessed his forbidden desires, she reassured him and gave him permission to do with her whatever he wanted, there were no more pains just the two of them naked and joyful.
