It was quiet hot but hearing a knock on the door I locked my smartphone and opened the door.She was there again to check my grandmother and see if med...cation worked or not. After filling her report she saw me and smiled. I also smiled back. She asked for my phone as it was an HTC. The looks of my phone caught her attention.She asked if she can see it, to which I handed over the phone to her. Next, she wanted to check the camera and asked if she can. I was completely taken aback and forgot what. . Uhn-gah, Yeahh! Oh God! Baby! Mmmm, do it to mommy, make mommy cum, YESS NOWW! I’M CUMMING JACK! . . cum with me, ohhh I can’t help it! I’mm CUMMMING AG_GAINN!!!” Then she caught a movement in the corner of her eye and looked in that direction. Their door swung open, and a naked Jack was standing there, his hand on his dick, shooting a long rope of white goo like a streamer.Mandy heard her son bawl out, “I’m cumming in you, Mom! I’m giving you my cream inside your sweet pussy, right. I’d never understood why Lindie never wrote to me or Russell to my brother Terry. There was so much that I didn’t understand. So much that I wanted to know over the years. But as our lips separated and Lindie dragged me inside of the sanctum that had been closed off to me, I just let those questions slide from my mind.I glanced around the kitchen where the four of us had played on rainy days, raided the refrigerator, and generally raised mayhem. I glanced in a complete circle, drinking in old. My own prick had become hard by now and I took it out and started jerking off Mom said " get between my legs and rub your cock on me it will help you cum, just stick it in me, OK." I agreed and took my pants off and climbed up on the bed my cock was leaking pre-cum already.In all this time I had never thought about having sex with my Mom, but her pussy was so open and so wet I wanted to just fuck the shit right out of her, but I couldn't, so I started rubbing my hard-on up and down the wet lips.
