Several weeks ago my wife Sue told you of her fantasy to be spanked by our friend Dave. Following that we had a few friends around for a few drinks the first saturday of the new year. Among these were Dave and his wife. As the evening went on I said that she should approach Dave and tell him of her fellings. She has no problems with straight forward flirting or chatting up but this had her beaten. Even when everyone was quite well oiled she just kept looking at him and having the odd chat. Eventually after everyone had left we got chatting over a last glass of wine and Sue said she was so turned on by thoughts of Dave she wanted me to spank her. She became very insistant even though apart from the odd slap on her bum I had never done anything like this before. Even though I protested (feebly, though I might add) she has her powers of persuasion. Sue stood up and undid the zip at the back of her dress, eased the straps off her shoulders and allowed it to fall to her feet. She stepped out of its crumpled pile on the floor standing there dressed only in a matching red bra and thong. She cutely wiggled to her handbag and took out her hairbrush walked to the sofa and told me in a cooing sexy voice to come across and sit in the middle of the sofa. How could I refuse. I sat down, she gave me the hair brush and lay face down along the sofa with her hips on my thighs. Her arms outstretched above her. \"Undo my bra\" she said and proceeded to take it off. \"Now I want you to stroke and fondle my ass\" I did this for a minute or two and then she said \"Now you are going to smack my bum with your hand\" I gingerly did it a few times then she told me to be a bit harder. Her cheeks were now beginning to pink up a little. \"Now you must use the brush because I have been having very naughty thoughts about Dave and you must punish me\" Feeling very apprehensive I brought the brush down gently onto her right cheek and waited for a reaction. None came. Then I brought it down a little harder onto the other cheek. This carried on for a few more smacks then I stopped as she reddened up a little. \"why have you stopped\" she snapped \"I was beginning to enjoy that\" \"sorry\" I carried on smacking each cheek in turn. Each stroke delivered with a slightly harder force. She now began to groan in pleasure as the strokes noisily slapped into her beautiful bottom. I started to enjoy what I was doing. Between each stroke I took a little time to listen to her groans of pleasure and to plan where the next stroke would be delivered. I carried on spanking and felt my groin start to swell into an erection that pushed against her stomach. Eventually she said \"I want you to do one more time on each cheek but I want you to do each one as hard as you can\" I raised the brush quite high and aimed at the middle of her left cheek. I brought it down as hard as I could her cheek rippled then involuntarily clenched tightly. For the first time she squealed in pain. then for the last time raised the brush again pausing for several seconds. As I brought the brush down even harder to her right cheek she sensed it and tensed just as the brush crashed home right in the middle of her cherry red cheek. She squealed again then brought her hands down from stretched out above her head to comfort her glowing buttocks. I started to gently rub her very hot and red bottom. She groaned in approval pulled her hands around to her front and started to fondle my powerful erection. I slipped my hand between her cheeks and slipped her thong to one side. I probed and found a soaking wet pussy. But as they say thats another story for another day.
