I am a tired soccer mom dropping my son off at practice. It is a hot day outside and my son takes his shirt off during practice. Between that and the junk moving around in his athletic shorts it's getting me quite hot and bothered. Even though it feels so wrong touching myself from being turned on my my own son I can't help but pleasure myself. My book isn't doing a good job of distracting me. Eventually, I move to the backseat where I first use a makeup brush and then a bullet vibrator to get myself off. I surprise myself by squirting all over the backseat. My son then opens the car door to find me...
