Disbelief

I walked yesterday to my 18yr old son wanking his cock. I’m utterly in disbelief. My son has the largest cock I’ve ever seen in real life, at least the thickest slab of meat. I gasped as he stood there jerking that beast. He just smiled, he didn’t even stop stroking. I think he meant to leave the door cracked. I went straight to my room as I felt my thong drench. I played with myself to the thought of him jerking and burying in deep in my hungry c**t. I’m a terrible mother, terrible for wanting my sons cock. Terrible for climaxing to him. Terrible because now that I know what he has, I want it and I know I’m going to try and ride it.
