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.
I nodded yes and that brought a big smile from my son. He lowered his face and he started working on both my large nipples. My husband rarely wants sex these days. I needed Rob in the worst way. As my son was sucking on my tits, I could feel the tip of his cock pressed against my opening. I had to have him. I reached down and brought his cock to my folds. Rob looked at me and then began to slide his massive cock into me. God, how I missed that! I pulled my legs back and gave Rob full access.
There was no wasted effort. Rob pushed his cock all the way inside my belly. He rested it there, letting me feel how big he is. I clamped down hard and squeezed his rod with my muscles. I think we both had one thing on our minds. Rob was going to give me his first load of cream without me being on the pill. That is just how it worked out. Rob brought me to a hot boil over the next hour. His thick member stretched me like no other man I ever had sex with. We climaxed together.
