my sister in-law

My s****r in-law, I really can not believe my luck, my s****r in-law has taken advantage of me since the day I married her s****r. It started at my wedding night reception, we were having a smooch, and to my shock she whispered in my ear I have no knickers on and then I felt her hand down my pants, I was soon very hard. She removed her hand and whispered if they play another slow song I will wank you off, but I expect a good fingering in return. I was very excited and at the same time I felt guilty and worried about my s****r in-laws age. The next song was 10cc I’m not in love and the smile her face told me she know what she was doing. I tell you what happened next was fucking amazing. She put one arm around and pulled me close at the same time she slipped her other hand down my pants and started stroking my cock tightly rubbing up down the whole shaft. I looked around to check no one was looking then I felt my way up her very short skirt and my index finger went straight in to her bald and very wet pussy and I pushed it in. She started to increase the speed of jerking actions and I was very close to Cumming. So I slipped another two fingers into her pussy and pushed them deep into body, she put her mouth to my ear and said one day I’m going to fuck you. And then she withdrew her hand and said the song has nearly finished so you better remove your fingers quick. I asked her to meet in the car park in 15 mins so I could fuck her, but she said that’s not a good idea im only 15. To cut a long story short 4 weeks after that she gave my blow job swollowing every last drop. We have had sex 35 times, I have given her oral sex 6 times she has given me 237 hand jobs she loves cum spiting in her face, and 56 blowjobs swallowing all the cum. But what I enjoy most is every time we see each other she always lets me play with her tits every opportunity she gets them out for me. I must just tell you about one night, my wife had gone to a hen night and I was at home with k**s about an hour after the k**s had gone to bed the door bell rang and it was my s****r and mother in-law they had been Xmas shopping and dropped in on the way home for a cuppa. After I made them a cup of tea we sat in the dark watching a film, but our three dogs were asl**p on the sofa leaving two armchairs. My s****r in-law said I will sit you lap so I said ok. I was hard for the whole film as my s****r in-law kept pressing her nice firm ars up and down my cock. The film had ended and the lights were back on. But as we sat chatting I felt my s****r in-law undo my zip and I could feel her hand on my cock the next thing I knew it was out , she wriggled about a bit and then I felt my cock enter her fanny ,I could not believe it. Then my mother In-law went to the loo, so my s****r in-law decided to give me a blowjob instead, but at the moment my cock entered her mouth the mother in-law walked in. She did not say a word instead she started undressing, she stripped naked and she looked fucking very sexy. She said I haven’t had any sexual activity for over ten years. My s****r in-law left the room without speaking. I sat there by now naked and invited my mother in-law to sit astride as she sat my cock diapered up her fanny and she started to ride my cock ,it didn’t take long before she started getting very excited, she started shouting please cum in me ,fuck me and as I shot my load she had an amazing orgasm. What a night that was.
