I may have underestimated Gina.“And what did you see exactly” I asked knowing full well the answer.“You know what I saw” she said “you horny...bastard”“Well tell me”“I saw Sharon with her skirt up and you playing with her”I moved closer to her as she bent on all fours scrubbing the floor. I was determined to have my way with her. I noticed her face was slightly redder than normal. Maybe the blood was rushing somewhere else as well. She was wearing a light blue standard uniform that was low cut at. As she suspected and hoped he might, he grasped her panties at her hips and languorously slid them down her long legs, dropping them around her feet. And then, nothing. She imagined him grinning at her predicament, she thought she could feel his hands less than an inch away from the cheeks of her full curvy ass, massaging and pinching the air in just the way she wished he’d really do to her. Shifting her weight from one foot to another she fairly screamed out with her mind, Hey! Naked horny. He wrapped his hand around his shaft and I felt him lining up the head of his cock with my asshole and he made his first attempt to penetrate my asshole. “Relax your ass, baby I’m knocking on the door and I really want to come in.”I encouraged my father not to stop as I pushed back on his head, “Oh yes, daddy slide it inside of my ass.” Once his head finally slipped in I began to tense up it was a lot larger than I expected. It’s one thing when you’re used to taking a cock in your pussy but. The kissing gave way to moaning. "BEN. BEN, YES, YES, YES, RUB HARDER, SON... RUB INWARDS... PUSH YOUR FINGERS IN (but she knew that the fingers couldn't go in because of the pants)... YES... YES, YES, GOOD, THANK YOU... DON'T STOP... DO IT TO MOMMY... DO IT..."Ben was in his own throes of wild thrill. "MOMMY, OH MOMMY... YOUR HAND IS GOOD... VERY GOOD... YES, STROKE ME, MOM, STROKE ME... DON'T STOP... AHK... AHK... AHK..."On and on mother and son stimulated each other. For ten minutes Rachel.
