She had fallen in love with me and after a previous loveless marriage I think she was keen to please the man she fell in love with so indulged my litt...e kink. (I may divulge details of other occasions in future).I was living in a different part of the United Kingdom from her and she had came to visit for a long weekend and was staying at my flat when the following event took place.I had taken her out to the pub so I could watch the Monday night football as was my usual routine when she not. I said yes.I said I had come in my friend’s car. She said she would drive me to her place in her car and take me back home when I wanted.I went to tell my friend and returned to her.She put her finger under my jacket at the back and up under my shirt to the base of my spine then down my arse crack.I began to get horny. She took me to her car which was a 70’s Mercedes.She said that it was older but in perfect condition just like her.She was 42 and I was 31.We drove to her apartment and she said. "Oh Jeez! This was so wrong! But he didn't have a choice. Karen slappedhis penis back and forth. He was aroused and getting more so with everyslap of her hand. Before he could stop himself, he began spurtingexcitedly."Oh my God!" Karen exclaimed. She hadn't expected this! Looking up shesaw her brother's face contorted with embarrassment and excitement,caught in the throes of his orgasm. "Look at the mess you're making! It'sall over the floor!"He couldn't stop. His penis continued to spurt,. She jumps over and desk, and lands on me causing the cheap chair to squeak loudly and tip over and we both hit the ground. ‘Ohh!’ Is all came out of my mouth as I hit the ground. She may only weigh what feels like 115 lbs., but it still hurts when you land on concrete, in an uncomfortable chair. ‘How did…?! How…?!’ She starts to say but is unable to complete a sentence, ‘Oh, my God!’ Comes out and it seems that’s all she can say right now. She gives me a full kiss on the lips, but I’m not.
