You are out of town and order an escort to your Hotel to release your pent up penis explosion. Once the escort arrives, it's your Mom!!! She wants to chat or hang out since you'd already paid for the hour. But you are very horny!!! So being the cool Mom that she is, she tells you to start masturbating and that she is your escort for the hour and will do what you ask other than having sex, touching her vagina and butt.
You start telling her what you want: kisses, tongue, breasts and hugging. Eventually, you are about to cum and she tells you to stop masturbating and put your penis between her legs...not her vagina and grind HARD until you cum
