I walked out to the parking lot with Diane close behind me. She was in a hurry to get into my car and close the door, so she was visibly relieved when... she saw I had moved it right up to the entrance. She rushed down the steps in front of me to get in only to find the door locked. “Please hurry before someone sees me!” She whispered desperately. I pushed the remote to unlock the door and she jumped quickly inside only to land on her bag of clothes. “You bastard!” She squealed as she ripped off. Even more terrifying was the hand impression pressing down now on her stomach. Yet glancing around the room she was totally alone.As she watched the hand indentation she suddenly saw a cut mark appear in the bottom edge of her skirt and watched as the cut moved in sections up towards her waist. It was as if someone was using scissors to cut off her skirt; then the skirt was whipped out from under her bottom and the hand indentation now moved to her thigh very close to her panties. She almost. .Oohh..Oohh…. Yeeeaah…(breathing heavily)Me: (while cumming) ohh…oh… yeaaaaah …![i cummed right between her pussy lips on her nighty and the area of the nighty squeezed between her pussy lips and my cock was wet and smelling of our juices and cum.My body which was tightly wrapped against her backside of her body was sweating out of control.And we both were trying to cool down our breathing.Her breathing was cooling down and she laid her head down and her eyes were closed,i took the opportunity. Suddenly my Father tapped my shoulder and I slipped my cock out of my Mother, almost leaving the as of yet still unfilled condom inside of her vagina. I collapsed beside Mother again on the bed as Father started to have sex with her, as he had started to do prior to my interruption. But as I started to relax next to Mother she turned to me and in the middle of her groans and grunts and other strange noises that I am sure would frighten a Poltergeist at night, she begged for me to put my cock in.
