Helen could not resist. It was if it was always meant to be. There was an irresistible force controlling her cunt, which had only one desire, to get a...l of her son's young cock right up inside her... NOW. She wanted his sperm inside her. She had always wanted more c***dren but with what happend after having Mark it was inpossable."Oh Darling, Mark darling, Do you want to sleep in Mummy's bed every night for the rest of our lives? Do you want to fuck Mummy all the time? "Oh yes Mummy! YES! YES!. No problem for her as we have often been together naked in sauna, also on nudist beach. But all other times it was together with my wife also. So I got naked and got in water. I turned around and I saw how she also undressed naked and then slowly walked to water and inside lake. Even if it was evening and sun was already getting down, I saw her body so perfect. I always loved to look at her body. Long legs. Big, round ass and really big tits with big areolas around nipples. We were swimming,. As soon as I'd latched on I punched out with the heel of my right as hard as I could, aiming squarely at the knee a foot or so above.The last time I'd done that move, in about the tenth grade, I'd crippled the kid. He'd been a football player, one of the school jocks trying to show off for his buddies by shoving the wimp around, and I'd caught him by surprise and pretty much shattered the joint. He was out of football for good after that, the knee was shot. His parents had made a lot of noises. His hand by now had gone towards my groin, somehow I wanted to stop him, his newspaper slipped from his lap, he had a full erection. I had seen many cocks in men's changing rooms but this was the first time I was feeling excited. He had a beautiful bell end and a thick shaft, he pulled my hand over towards him, I didn't resist, I began to wank him, after a few minutes he let out a very contented sigh. His sperm shot like a string of beads onto the grass between us. He took a few minutes to.
