i have been divorced for about 8 years now and my two sons are now older so instead of a set day they now come round to visit or stay when they want. A few months ago my eldest 20, phoned to ask could he bring his girl friend and stay the night no problem. they arrived just as i was leaving to go and play darts at my local. It was a quick hello but i did notice she was quite a few years older (I later found out 11) than my son. I arrived home the flat in darkness I thought they were both out but as I passed the bed-room the very loud sounds were of a couple having a good fuck. I tried not to listen but they were very noisy and of course I was soon hard so had a wank. I awoke to the sound of my sons groans, she was quiet obviously her mouth was full of cock. I went to have a shower giving my cock a good rub till I came. I started to dread them coming over as they were so noisy and loud when they were at it I did not want my son to think I was listening intentially. They took me out for dinner one night to say thanks for leting them stay over and I have to say she was a very sexy lady. I saw her looking at me a few times with a sly grin on her lips and it clicked then, she knew I could hear them. My son went to the loo and she leant in close I got a good view down her dress, she whispered I hope we don`t keep you awake but your son is so horny. This woman was now full on her hand stroked my arm, I tried to keep a distance but she was having none of it. I noticed she kept topping my sons glass up so by the time we left the restaurant he was very tipsy. We got back to the flat she said I would like a nightcap I brought the brandy out I had none, she a very smal glass but she poured my son a large one. Soon my son said I have to go to bed and tried to take her with him his hands were all over her he had forgot I was there. She let his hands roam over her and she was touching him. I left to go into my room so I could not see I tried to sleep but could not, it was all quiet from the other bedroom so I quietly got up to make myself a coffee. I was standing in the dark looking out of my kitchen window drinking the coffee when the voice said I would mind one of those. I knew deep down what was going to happen next but I should but did not stop it so let it play out. I made the coffee handed it to her all she had on was a T-shirt which hid nothing, he is out for the count to much booze she said. We went into the living room not puting on lights, of course now my cock was rock hard, I heard her snigger I know you want to give it to me and you can, having a son and father is part of my bucket list. I said no its not going to happen but she stood up walked towards me lifted the T-shirt a little so a could see her cunt. Come on just get that hard cock out a fuck me till i am sore. I grabbed the T-shirt dragging her the last few inches pulling her over my knee. Oh yes please smack me and for the first time ever I smacked a womans bottom hard. She squealed harder, I did then I pulled her legs open pushing my fingers into her cunt she was wet and slippery. I jambed my fingers in hard time and time again she just got wetter. She twisted round pulling at my shorts till my cock was in her mouth I put my hand on the back of her head pressing her down she deep throated me like an expert. I twisted my hand in her hair pulling her up and down on my cock and soon she had mouthfull of hot spunk I wanted to abuse this woman and I am not proud of it but she lapped up everything I did. She soon got me hard again, no going back now I fucked her my hand over her mouth so she couldn`t make any noise. When I was finished I stood up to walk away, she lay writhing like a snake on the carpet she opened her legs and started to frig her herself to have another orgasm it was like she could not get enough. As left her there my guilty thoughts were my sons GF but I knew if she made a move again I would fuck her senseless. Four weeks have gone by and I have avoided them like the plague my only hope is she will get bored with my son and finish with him
