Sister surprise

Note : This story is completely fictional!

well it all started when i was a little younger, my sister had a friend that used to come round to our house nearly every day called jane , well jane used to play fight with me and try to get my trousers down all the time but she never did it and some times my sister mandy would try to help her but they never did it as i was too fast for them.

when mandy used to go out drinking with her friends and got back home late at night she would always be drunk and i found her naked on the bathroom floor a few times and lying on top of her bed as well she had a fantastic breasts and a very sexy body with nice shaven pussy i always got an erection when i saw her but nothing ever happened .

so i moved down south when i got older and she still lived up north we still phoned each other a few times but when it got to her 40th birthday i got told to come up to a surprise birthday party for her , when i got to the pub she was in and walked up to her god did she look sexy sat at the bar and all the memorys came flooding back to me of her naked on the bathroom floor and gave me a mighty erection, the night went on and i got to know another of her friends god would i like to get to know her better she was sexy to say the least,half way through the night i was stood next to mandy [my sister] and her friend ,her friend kept asking me if i wanted a drink i knew if i did i might do something that would start trouble so i said no . mandy was very drunk by now and started telling me how much she realy loved me,i didnt know how to take it as she was drunk, i was surpossed to be staying the night on her settee but knew if i did i would try to shag her and didnt know if it would cause trouble so drove home bavk down south regretting it all the way home.

a few years later i was coming to my 40th and was going out drinking with my sister and a few friends and her friend lisa the one i met on her birthday was there as well and i was staying on my sisters sette the night so i could have a drink, we had a great time and the last bell went and we all went back to my sisters for a last drink, i fell asleep in the chair as had a lot to drink but when i awoke there was nobody there at 3 am and the lights down stairs was of but somebody shouted and woke me up didnt know who , i needed to go to toilet so made my way up stars and saw that my sisters light was still on and door was a little open,thoughts of her lying on the bed gave me an instant erection,so i had to have a peek to satify my mind ,so just peeked round the door and what a sight i saw my sister and lisa doing the 69 position with my sisters head away from me so i saw her pussy and her friend with her tongue in my sisters pussy licking her clit, so i had to get my cock out and start playing with myself this was too good to be true, i got a bit more braver and sneaked into the room hoping to to be heardand watched a bit longer and thought well now or never so took my cloths of and crept up to them playing with each other my cock in my hand ready for anything , moved just in line with my sisters pussy and took aim and pushed my erect cock as far as i could push it deep into her pussy and she moaned oh my god yess so i started to pump faster and then she realised it was me shagging her and said stop this is not right and asked me to pull out , i thought of my god im in trouble now what shall i do, so i slowly started pulling out my god lisa was licking my cock as i was pulling it out i nearly come on the spot,as i was pulling out i heard my sister moaning so i thought il push it back in hard and see what happensand lisa licked my balls god it felt good,then i said to my sister do you realy want me to pull out and lisa said no just fuck her she will enjoy it and then my sister turned to me and said well we are passed the taboo stage now so you might as well fuck my brains out which took my breath away, i thought well if she wants my cock shes going to get it and started pumping my rock hard cock in and out of my sisters pussy while playing with her fantastic nipples, while lisa was licking my cock going in and out her pussy i let it fall out a few time and lisa put it straight in her mouth and sucked it then put it back in my sisters pussy , they swpped places and my sister was licking my cock as it slid in and out of lisas pussy we carried on like this for hours until we all fell asleep . when i woke i thought it had all been a dream but when i saw lisa and my sister lying naked next to me my cock was erect straight away, so i decided to go down on my sister and lick her pussy which i had only dreamed about until now and while i was licking her i felt a warm mouth round my cock as lisa was giving me a blow job we played swapping around until we all came then got up cleaned up and got dressed. god what a brilliant night it was couldnt have dreamed any better,when we were all down stairs we started talking about the night and i was told i was surposed to get up a little later and find lisa in the postion i found my sister in and shag lisa and not touch my sister but after my sister had my cock in her she didnt care it was rong and just wanted more, from then on i visit my sister at least 3 times a month and all three of us have great fun together and we have talked about asking jane to join us as well , well that could be another storie if it happens hope so well if it does i will put it on line
