I'm laying in my bed next to my stepson. We are both naked and he is on his side facing me. I reach over and start to jerk him off with my hand. He spreads his legs wide and lays down flat on his back. I continue to jerk him off and he starts pumping his hips up into my hand. I can feel the warmth of his cum starting to fill my hand. It feels great! I keep jerking until he cums all over my hand and body. I am a good stepmom.
