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.
Then I felt his large tip against my pussy and I pushed my hands flat on the table as he started to push it in. I could feel my pussy lips stretch as his tip went in then he carefully slid all of his long thick shaft into my wet pussy. I felt so full and already tingles of pleasure were surging around my pussy. Mark held my hips then he started to thrust in and out slowly. Whenever he pushed back in I moaned as my pussy stretched around his dick each time. As he gradually sped up I was moaning more and more and I could feel my nipples were like bullets in my bra. I would have loved to be naked so they could have swayed freely but still I did have a huge dick in my pussy so I can’t complain. Mark was pushing every one of his inches back into me everytime and my pussy felt like it was burning. As he sped up more his balls were smacking against me making me even more aroused. I could hear him breathing heavily and I hoped he’d make me come before he did. It now felt like electricity was darting from my pussy as he rammed his dick in and out of me and I was moaning even louder now.
Feeling an orgasm building inside me Mark kept thrusting and just as he was all inside me I started to shake and I shouted as I came hard to a shuddering orgasm. My body was shaking and I guess my pussy must have tightened around his dick as I heard Mark groan and felt his dick buck inside me as he came hard in my pussy. When we both stopped coming he gently pulled out of me and collapsed on the chair. Standing up I looked for a tissue and saw a box by his bed. Walking over I took some and wiped my pussy before I cleaned his dick too. As I put my panties on he put his now soft dick away then after he turned off his computer we went downstairs to the party. Karen saw us and said “Where have you both been” and I replied “Just talking”. Mark smiled at me and I smiled back before going to get a drink as I think I earned it.
