Standing With My Cock In My Girlfriends Pussy

This was in England . I was 17 , my girlfriend was 16 . We both liked to have sex . One night we were at her house . Like most English Council Houses (the local authority owned them) , All these houses were basically the same . They were built in blocks of two . Mirror images of each other . They had a front door , at the front of the house . A back door in the rear wall . This door was in a porch . A square brick area about five feet square . We sometimes had sex in there . If it was dark , or in the winter . I would unzip my Jeans and take my cock out , she would lower her panties or remove them . I woold stand with my back to the wall , facing the back door . My girlfriend would stand in front of me . With her back to me . I would wear a condom . Lifting the back of her dress and fucking her . She had a sister 3 years younger . We had done this many times . No one had come to the door , it was always locked . This night as i was fucking her . We heard the door being unlocked . It opened , it was her sister . She was excited to tell us some family news . I stood with my cock in my girlfriends pussy , just about ready to cum . I could not pull out . I had to stand there looking innocent . She seemed to talk for ages . I was excited seeing her . Knowing where my cock was . So my erection stayed hard . After about 5 minuutes she went back in to the house . I heard her lock the door , i fucked my girlfriend . Cumming almost instantly . When she was about 12 , her sister had shown me her pussy . My girlfriend did not know . We had been sitting on the couch , watching tv . My wife was facing the tv . Leaning against me , facing to my right . I had my back to the arm of the couch , watching the tv over my right shoulder . Her sister was in her bedroom . She came down and climbed on to the far end of the couch . She did she did not sit down . Crouching on the couch with her legs wide apart . Giving me a clear view up her dress . Showing me that she was not wearing panties . Showing me her pussy . As she was standing there talking . I was remebering seeing her pussy .
