It was my sister Karen’s birthday and I’d been invited to the party her and her husband were hosting. It was to be a small party apparently. Their son Mark would obviously be there and a few close friends of theirs. When I got to their house I was the first to arrive. Karen opened the door and we kissed and hugged. “You look lovely Emma” she said and I replied “Thanks so do you”. I was wearing a new short light blue dress with and matching handbag. With my straightened long brown hair and my big boobs sticking out I did look attractive. Karen was wearing a red top with a short black skirt. Her boobs were smaller then mine but she had the nicer bum.
Karen led me to the lounge and her husband Ken was in there looking smart in a black suit. As I sat he passed me a drink and we all talked until her friends arrived. They all seemed to arrive together and I was introduced to them all. As we began eating snacks I said to Karen “Wheres Mark?” and looking around she said “Probably upstairs playing on his computer. I’ll go fetch him down”. “Don’t worry you see to your guests and I’ll go find him” I replied.
Putting my plate down I went upstairs and approached Marks door. I knocked but he didn’t answer so I opened it and saw Mark looking at his computer with his dick erect in his hand and what a dick it was. At least nine inches long and as thick as my arm. I walked in and shut the door then I said “Hello Mark you enjoying yourself?” He looked around at me, jumped up and tried to put his dick in his trousers. Stuttering he said “Aunt Emma I didn’t hear you come in”. Smiling I replied “I did knock but you were busy I see”. He was red faced and still trying to fit his dick inside his trousers as I walked over to him and said “Don’t be embarrassed. Most people jerk off Mark”. Looking at his computer I saw he had been watching a porn film that he had paused. A lady was bent over a table with a man with a huge dick inside her pussy.
Turning to Mark who had now given up trying to hide his dick and was just standing there with it throbbing I said ,”You like this position then?” and hesitantly he replied “Yeah I do. My ex and I did that position a few times”. “It is a great position for making a woman come” I said. While I was talking to him I realised my pussy was so wet and seeing his hard dick I wanted it inside me. Now I know he’s my nephew but we’re both adults and besides I could do with coming. A couple of my ex’s had big dicks so I knew how wonderful they felt inside me.
“I came up stairs on behalf of your mum to ask you to come down to the party but obviously you can’t go down there with that” I said. Looking straight at him I lifted my dress and pulled down my white see through panties. Stepping out of them I turned to the table, bent over it and pulled up my dress before spreading my legs wide. Turning my face to look at Mark he looked unsure at first but then he moved behind me. Feeling his firm hands stroke my bum cheeks I felt naughty and excited then he slid one hand onto my wet swollen pussy lips and rubbed them firmly causing me to moan. Taking his hand away too soon I would have liked him to rub more but I was already wet so it’s ok.
