She made gasping sounds. Then Mum gave a final shudder and relaxed. All tension seemed to leave her body.We lay there for a few minutes without saying... anything. Then Mum said, "Come up to me Mark."I slithered up Mum's body until our heads were side by side."I'm sorry, Mum. I came home early yesterday. The bedroom door was open and I saw you naked in bed. You were so beautiful. I couldn't get the thought out of my mind. I almost went crazy thinking about seeing you and I had to see you again.. Sarah got off the bed and pushed me down onto the bed. Dropping to her knees she took me into her mouth. Sarah's tongue pressing into the underside of my cock felt fantastic. She looked into my eyes the entire time, letting her lips slide of the top briefly, taking a breath before again forcing the entire length into her throat. She began to moan, the vibrations making it harder and harder to not cum in her mouth. Sarah's fingers were rubbing furiously and she came again with my dick near. To be honest, parking on-street wasn't that bad. We lived in a safe neighborhood and the lanes were wide enough that no one had clipped any of our cars. But my sister and I were particularly picky due to our mom.Mom died in a car crash when Jenny and I were only 2 years old. We know it's completely irrational to worry about parking on such a safe street due to this event, but it is what it is. We weren't the only ones to suffer repercussions about Mom's accident. Obviously, Dad was completely. She moved about a half inch, then started to choke. It didn't matter. "You're going to take the whole thing," He said. He pushed her down, almost violently, and her lips were suddenly at the base of His cock. Her face was stretched out on its girth, the tip was deep in her throat. Tetenia squirmed, her body writhed, she gagged and gagged some more."We are in thrall to you."His Supremacy held Tetenia firmly in place, and sighed contentedly. She began to massage the base of His cock with her.
