I do not know what has gotten into my son! He has changed overnight. I went into his room this morning to wake him for school. He had an erection as usual. I told him to get up and get ready and do what he needed to do to get to school on time. I walked backed to my room to change for work and as I took my pajamas off he snuck up behind me bent me over my bed and started fucking me really hard. He held my hands behind my back so I could not move. I was so angry but at the same time turned on. When I thought he was finished he let up and I turned around to scold him some more. He replied by shoving me onto my back on the bed and fucking me some more. It was starting to feel good but I was not letting him know! He came all inside of me and thought he was going to leave me unsatisfied with his cum dripping from my pussy. Well that fucker was wrong! I told him to man up and finish the job. I started riding him so I could cum hard too, Bastard started to get soft so I sucked it for just long enough to get it hard again and last long enough for me to cum. Then I told him to get the fuck out of my room and get ready for school. Now he knows HE's NOT done until I say he's done!
