Our eyes locked, and I hugged him close."Thank you Dad, for taking me shopping."He pulled away with a shaky breath. I could see the outline of his par...ially erect cock through his pants. I turned back around and let him unzip me. He abruptly left.We drove home in a tense silence. He said he was going to watch TV. I was pleased with all my new stuff, but I was still really horny. I started thinking about my Dad, and how handsome he was. Tall, and 6'1" with salt and pepper hair and the bluest. I began licking her butt-hole, while occationally teasing her pussy. After tickling her lovely backdoor, i pushed her booty all into my face and stuffed my tongue into her asshole.I bent her over and thrust my cock at her tight love hole. I pushed my head slowly into her anus and surprisingly the rest slide right in. She didn't even flinch. I grabbed her ass, digging my fingers in as i slowly pulled her back. She whimpered a bit as i slide her ass hole all the way down to my balls."You like. ..No...no, John, please," Marci said. Shhhhhh, quiet, I know this is the second time tonight...I know your exhausted and sore, I know it will be painful...you will soon rest," I whispered. " Don't pull away from me, Marci...Don't you ever hold yourself from me." I said menacingly. She lay there whimpering quietly, she lowered her head to see my hard thick long, extremely hot cock shooting disgustingly copious amounts of pre-cum all over her, giving little jumps when it squirts directly onto her. "MOM!!" I said, "There's no way. I'm sorry this happened, but it will go away." I knew I was lying and so did she. "Look, you are your father's son. I know him and I know you. Neither of us will sleep with you in this condition so just do it, I don't mind." Besides, we're going to need all of our energy tomorrow." She ran her hand up and down my hip and pressed her ass into me. I knew she was right. Tomorrow was going to be an exhausting day, especially if this rain freezes. And no way am I.
