About a year or so ago my mum decided that we had a spare room so why not use it. My mum is a nurse, and her hospital trains up new nurses. She had a new nurse start there called kelly who was 20 at the time. Kelly was in her final year of a nursing degree, and needed a place to stay near her work. So my mum and dad talked it over and ended up asking her if she would like to stay with them. They charged her a modest amount (in fact a generous amount for inner london at £90 a week), and let her eat with the family. At the time i was at home for my final year at uni, and my youngest sister stayed at home too. I was 20 but 6 months older than kelly, and my sister was 17.

Kelly was not an absolute knockout and at first i thought she was boring and normal looking. I have a girlfriend who i love and cherish, but anything different and im like any other guy... lustful. Kelly wore glasses had average sized tits, but a really lovely soft ass. She was shy at first around the house, but after a while she would come downstairs to watch telly in a small top and these little black shorts. Which would let just the bottom of each cheek of her arse hang out. I didnt look at first, however all of a sudden i found myself unable to stop staring at the crack of her arse as she walked away, or the cleavage between her tits as she bent over. I told myself i was being silly, because to be honest my girlfriend is much fitter with a nicer arse and bigger more rounded tits. However, as i said anything different!

I knew that sometimes she noticed me looking, and she must have thought i fancied her because every now and then she would flash me a smile or a look over her glasses seductively. I thought she was just teasing until one night about six months after she moved in.

My mum and dad were always a 'one bottle of wine a night' couple, and the lodger was no exception. She would also drink every night, maybe it was something to do with the stress of being a nurse.

My mum and dad went away for their summer holidays and took my sister away with them, me and kelly both worked so we met up in the evening. The first few days all we did was sit there watching tv on the couch, however this soon progressed to us having a few glasses of wine and snuggling. Now snuggling is not what i would call cheating, it was an arm around the shoulders. However soon the snuggling turned into a cuddle, then into an embrace. And after a few more glasses of wine i had lost all inhibition, and so had she. We started slowly kissing, our tongues twirling around in each others mouths. She was wearing a small top and her little shorts. I was wearing nothing but my shorts and a top. I am pretty athletic as i play (played) rugby for the uni, so she wasted no time in running her hands over my stomach. Suddenly we broke off as my hand was just sliding between her pussy lips. "This is wrong, sorry" she said. Then my world came crashing down, and i realised this was the lodger, what an idiot i had been. I thought about my girlfriend, and stopped then and there determined that something like this would never happen again. All the while wondering why she had been so wet, and why i had been so hard.

Perhaps it was fate, i dont know. However a few days later we had a few bottles of wine and ended up in the same position. Only this time i worked her small shorts off and started fingering her tight hole. She grasped my cock in her hand, and rubbed it up and down as we tongue fucked each others mouths. This went on for an hour but we stopped, again feeling guilty.

My mum and dad came home soon after with my sister. We were watching tv one night and although after a long chat we had decided not to tell anyone or do anything like it again, i found myself sitting next to kelly rubbing her shoulder while everyone watched tv. Then my mum and dad went upstairs to bed and so did my sister. I was still rubbing kellys shoulder, with her hand placed on mine. Then my hand worked down to her breast, and went inside her top. I caressed her nipple, and looked in her eyes. We kissed and i put her hand on my cock, which by now was rock hard. She looked at me and i sai "look how i am for you" she kissed me again and i said "why dont you suck me". I pushed her head towards my crotch and pulled out my rock hard cock. Im no porn star, but i have a decent sized cock nearly 7 inches. She sucked it hard with her small mouth, and although i could tell she had little or no experience it was making me mad with ecstacy. Then we heard a stomping noise. The tv was still on, and we knew my sister was coming down stairs. I put my cock away and we sat up serenely, my sister announced she was going to bed, and kissed us both goodnight.

As soon as she went upstirs i grabbed the lodger by her arse and pushed her upstairs to her room. We lay on her bed tonguing each others mouths, and grinding her pussy onto my cock. Then i got my cock out and pulled my top off i was naked in front of her. She licked all over me, befor settling on my cock. Sucking and ;icking without much panache, but still she got the job done. I got her clotes off and we humped against each other for a while, whilst kissing. I sucked her tits, and licked along her stomach. Then i bent her over and stuck my tongue in her pussy, licking up and down her slit and into her arse crack. Then she got back on top of me and as we were humping against each other i tried to fuck her. However she kept whispering "no". But i kept pushing. This is how i know she had no experience because i ended up pushing my cock into her arse. Then once i was in i fucked her hard as she made small moaning sounds. At first i didnt even know i was in her arse, then i realised when i tried to finger it and ralised i was balls deep in it! After that all restraint wen out the window, i dont think she was a virgin but her puss was very tight. I ben t her over and fucked her arse then her pussy. Back and forth as hard as i could. It was in the dark and we were drunk so nothing was out of bounds. I took my cock out of her arse and told her to clean it so she dutifully sucked it, then aimed it back into her pussy.

As i was fucking her arse i was about to cum, so i grabbed her tits and said "babe can i come on your face", "wherever you want" she said. I flipped her over and she started taking her glasses off "no, leave them on" i insisted, so she pushed them back up. I then shoved the tip of my cock in her mouth and wanked furiously until i felt the telltale rush of cum. I then said "open your mouth baby", and as she did i squirted all over her face. She licked and sucked my cock, and rubbed her glasses and face in front of me.

Needless to say after that experience we were both so embarrased. And although i have tried to fuck her since, she has more success avoiding my advances than i do controlling my urges. So i still wish to fuck the shit out of her every day. Maybe its's better that way?
