I am going to make your buttocks red and sore now as I bring down my hand on each buttock as they redden nicely to my hand...As I continue to spank yo..., I tell Sandy to masturbate for me to view and as my hand again comes down even harder on your bare ass, I slide a finger into your pussy and discover you are soaking wet.As I complete 24 strokes on your bare ass, I tell Sandy to come over to us and to lick your fuck holes cunt and ass as I keep you firmly restrained on my knee...I tell Sandy do. "No, don't stop," she said. "I'm close. I'll come when you come. I want to watch your semen squirt out. I want to see its force and gauge its volume, so when you give me a psychic fuck I can use this experience to imagine your come flying into my cunt."David groaned, and when his hand made one last stroke, his balls lifted and tightened, and he felt semen fly up through his shaft and shoot into the air. His eyes started to roll back into his head as his body stiffened, but he forced himself to. He felt even more scared now, sure he had seen pussy in magazines, but this was his first real one so to speak and it was his mothers, the woman he loved most in all the world, he couldn’t draw his eyes away from her naked body, and now his hard cock was throbbing, it seemed to have a mind of its own. “You like mummy’s pussy? Would you like to taste it? Would you like to fuck it David? His mother smiled, spreading her pink lips pussy with her fingers.David’s hand involuntary went to his. I stuttered, “What? ..No, wait…what?”“Never mind,” she said, and quietly ate her food. Things got a bit awkward after that, as we finished our meals, in almost dead silence.She got up to do the dishes and turned her back to me. I weighed my options, but all I could see was that tight ass, protruding from her skirt. And I absolutely LOVE a woman in a skirt.I crept up behind her, and rested my semi erect dick on her ass crack, and hugged her from behind. She gasped but didn’t do anything to stop.
