About three year ago I was living with my girlfriend at her mothers house which, to go against the grain, was a fantastic time. Her parents were fun, especially the father who loved to lounge around talk rubbish, and drink cider. The days were a pleasure never hard. With every good time, though, I believe there has to be a bad time or a challenging time. That challenging time happened to be 6ft tall, twenty-seven, long dark hair very ample breasts, tanned slender legs that went on and on, a body to die for, that for my good luck, or my bad luck, depending on how you looked at it, was constantly flaunted in sexy underwear. Usually in the bedroom with the door slightly ajar just enough for peering eyes… Her name was Tracy, my girlfriends sister, and boy was she horny.. I hated seeing her dressed in a thong and stockings in her bedroom, for there was nothing I could do about it. The times that she came out of the bedroom to the bathroom, and just chatted to me as if nothing was different clad in black thong stockings and a bra that just covered her gorgeous tits, or was it that I just hung around there waiting for her to come out. I remember coming home one particular afternoon, whilst no one was in I decided to kick back with a beer, just as I was going to the kitchen I heard music coming from upstairs .I walked upstairs to see who was in, and could hear that the music, which was now quite loud, coming from Tracy’s room. Seeing as the door was slightly open I walked towards the door, with the intention of entering, but before I got to the door I heard, what I thought was a male voice. Intrigued I slowly stalked my way to her door. I got to the edge of the door and slowly, quietly peered in. Tracy was on her knees naked except for a pair of boots, sucking on the biggest cock I had ever seen the face at the opposite end of the cock was in absolute heaven moaning, and telling her how much he wanted to unload his cum down her throat. I could not look away as Tracy, like a porno star, took this guy’s massive cock down her throat. Then his legs started to buckle and twitch, his hips started to jump up and down off the mattress in rhythm with her. And bang he was coming and Tracy was gagging, she seemed to take it all down her throat. With a massive hard on, myself, I decided to get away as quick as I could and out the house amazed at what I had just witnessed. An hour or so later I returned, and with Tracy lying on the sofa, I tried to act as normal as I could. ‘I know, you was watching’ she said. Fuck that had done it, I could feel my face starting to burn, and any chance of trying to act as if I had no idea what was going on -with it. ‘Saw what’ I replied. Well it was worth a go even if I had been caught red handed. ‘Look I’m not going to beat around the bush, we have been teasing each other for so long now you want to fuck me and I you. end of story’ she said The fact that she had been the one teasing me was beside the point; yes I did want to fuck her. Before I could say anything else she went upstairs and told me to follow. I could not believe how up front she was being and was starting, as I reached the bottom of the staircase, to have second thoughts. by the time I had got to the top and saw Tracy removing her bathrobe any second thoughts had been thoroughly tossed aside. At her bedroom door, she stood, high black boots black fishnet stockings that went up forever, up to a little black thong and a beautiful pair of firm tits I had ever seen without further ado I stripped out of my clothes and stood before her in my underwear. We kissed, passionately, and we fell to the bed. I took the imitative and kissed her body down towards her beautiful now exposed pussy and started to lick her outer lips whilst every now and then I darted my tongue over her clit. Tracy started to moan and I went into her inner lips and started to slowly but gently lick, Tracy started to wriggle her hips, and I slowly guided a couple of fingers into her, now soaking, pussy. Hooking my fingers upwards as I did whilst putting enough prolonged pressure with my tongue on Tracy’s clit. This seemed to do the trick it did not take long for Tracy’s moans to get louder and louder, her movements to get more erratic as she started to explode. Her back then arced and she let out a loud moan as she started to cum … ‘I want you inside me …now!’ I stood up in between her legs. My god she was still wriggling on the bed as I dropped my shorts my erection stood up nice and proud. The sight of Tracy laying there dressed the way she was, was like looking at a model I new I was not going to last long. I kneeled before her and slowly entered my cock inside Tracy. Tracy wrapped her stocking legs around my back, and that felt good I slowly pushed my cock up to the hilt and she let out a satisfied moan as I slowly started to build up a good rhythm. ‘Come on faster, fuck me faster’ I started to fuck her faster and harder and the sweat started to roll off me I could not believe I was now fucking Tracy fast and hard, and she was moaning beneath me I could feel her getting closer to orgasm, and I started to feel myself starting to reach orgasm as well, and with a worry thought about slowing down. But Tracy had none of it she grabbed onto my ass and thrust me into her, that was it I decided I was goanna just go for it I started to fuck her as fast as I could so fast my rhythm totally went out the window. I was pounding her pussy hard and fast Tracy was now moaning louder and louder I could not control myself anymore, and exploded into her pussy just long enough to feel Tracy buck underneath me as she exploded. Finally I crashed on top of her sweating and panting feeling great. Well great until I heard movement on the staircase…..
