One day when I was doing laundry, I noticed my son Rob's cum stained undies. I was so horny I began to finger myself. Rob appeared and saw me. We ended up fucking in the laundry room. That led to a summer's worth of sex between us. Rob went back to college. Before he left he told me he wanted to impregnate me. I must have been crazy because I went off my birth control pills. Rob is due back tomorrow for a holiday break. My pussy is tingling thinking about his long prick.
Everything seemed to work in my favor. My husband had to leave for a short business trip. That would give Rob and me a few days alone. Rob finally arrived back. A friend from school dropped him off. I opened the door with just a robe on. Rob practically scooped me up and moved me to the couch. He untied the belt of my robe and pulled it free. I was standing there naked in front of my son.
Rob pulled his clothes off. I had almost forgotten how thick and he was. I needed that cock. I got onto my back and Rob joined me on the couch.
"Are you off the birth control?" He asked me.
