The whole thing started with a flu epidemic of all things, first mum, then dad then my sixteen year old brother fell ill, as for me I was the healthiest seventeen year old you could find, bugs bit me and they died, so I ended up as the nursemaid for the family. Luke was the one hit the worst, my brother had come down with the virus just as mum and dad were recovering and he got so bad we had to call the doctor out to him, after much poking and prodding the doctor mumbled something about secondary infection and put Luke on a course of antibiotics. Thankfully it was the school summer holidays so Luke and I didn't miss out on our schooling, but mum and dad had jobs to go to and as soon as they were fit enough they went off to work leaving me alone with Luke and boy did he need looking after. He had a high fever and for most of the time was sleeping, but when he woke he was delirious and thrashed about in the bed, at those times I would hold him and mutter comforting words which seemed to calm him.

One morning Luke started to thrash around, I was in the bathroom just drying off from taking a shower when I heard his weak cries and I rushed to his bedside still naked, when I got to Luke's room he had already thrown off the covers and was just about to fall out of bed. Quickly I went over and eased him back onto the bed then sat beside him and held him in my arms as his body moved restlessly against mine, his pyjamas were sopping where he had been sweating and I decided that before I covered him up I'd change them. With his restless movements it took ages to get his pyjamas off only to discover that there wasn't a clean pair to put back on him, by the time I realised this Luke was thrashing on the bed again and I decided that he'd be better off naked than clothed in damp pyjamas. Climbing onto the bed beside him again I pulled him to me and drew up the covers, his skin seemed to burn against mine and I felt really worried about his condition as he'd been feverish like this for nearly a week already and there were no signs of his fever breaking, even with the antibiotics helping.

I was so lost in my thoughts that I didn't notice where Luke's hands were, what finally attracted my attention to them was a growing feeling of excitement in me, with a gasp I realised that Luke had one hand on my boob and the other on my pussy, hell it was in my pussy, at least two of his fingers were. Just as I reached under the covers I realised that Luke was not moving restlessly, he was leaning against me quietly and seemed to be almost asleep, the thought struck me that he was calmer because of where his hands were and I decided, though I'm not sure why, to let him stay just as he was, once he was asleep I'd extricate myself from his clutches. There was just one major problem with that decision, as the minutes passed Luke's hands gently moving on my boob and in my pussy were getting me really horny and I mean really horny and when I felt his cock twitching against my leg I wondered if I had made the right decision.

Sighing I reached under the covers to move his cock away from me, but as my hand touched his cock it jerked to full erection and Luke gave a low sigh as though of pleasure, at the same time his fingers began to move more firmly in my pussy and his other hand started to tease one of my nipples. Of course what I should have done was to have moved his hands away from me and slid out of the bed, but Luke seemed to be at peace for the first time in days and I just lay there with my hand touching his cock and his hands exciting me more and more with each passing second. By the time another ten minutes had passed I was so excited that I couldn't have moved away if I had wanted to and with a groan I closed my hand around Luke's cock and gave it a gentle squeeze, his response was a sigh and to move his fingers in my pussy even more firmly.

It wasn't long before I could feel an orgasm building up inside me, panting and groaning with pleasure I began to wank my brother which made his hand move faster on me, which made my pleasure grow, which made me move my hand faster on him, on and on, round and round in a spiral of increasing pleasure that eventually had me shaking and gasping in climax. Even as I began to shake Luke was moving beside me, his head came up to rest on my chest and his mouth closed around a nipple sending me over the edge, but it didn't end there, Luke kept on sucking at my nipple, tweaking the other one and fingering my pussy until I thought I would explode with ecstasy and all the while I was wanking him. My brother may have been in delirium and unaware of what he was doing, but what he was doing was driving me crazy and when he suddenly kicked off the covers I could only lie there and gasp at the sight of his hard cock with my hand moving up and down on it. The next moment his hand had left my pussy and with a sudden, unexpected leap that pulled his cock from my hand he was on top of me and sliding his cock into my pussy.

"Oh Christ!" I gasped out as his cock slid right into me.

For a moment I was too stunned by what was happening to react and by the time I had got over my shock Luke's cock was sliding in and out of me so deliciously that all I could seem to do was to move with him. Young my brother may have been, but he moved in me like an expert, his thrusts were firm yet gentle while his withdrawals were slow and exciting, with this sort of heavenly treatment it was no wonder that I was climaxing within a few moments.

As I came down from the heights of pleasure my brother began to move a little faster in me, with a gurgling cry I was crashing into another climax followed by another and another, each time my peak faded a little Luke would speed up a little more and thrust a little harder almost as though he was fully aware of what he was doing. It seemed to take ages for Luke to reach his climax, but when he at last thrust deep into me and gave a shiver I was so far gone that I could barely croak out a weak, sobbing cry as I felt the heat of his seed filling me and spreading inside me, even then Luke kept on moving until his cock started to shrink, then, with a deep sigh, he rolled off me.

Shaking and quivering I held my brother in my arms as his juices started to seep from my pussy, in a way I couldn't believe what had happened, but in another way I was revelling in the sensations he had given me. I felt so confused, what I had let happen was wrong yet it had made me feel so good, I couldn't blame Luke because he had not been aware of what he was doing. I had only myself to blame for letting things get as far as they did and I did feel guilt and shame, but at the same time I was feeling so satisfied that it overshadowed my guilt and it gradually dawned on me that I wanted Luke to take me again, I was shocked at my feelings, but there was no denying them, I wanted to be fucked by my brother. Beside me Luke stirred and rolled onto his back, with a guilty start at my thoughts I pulled up the covers and felt his forehead, as my hand touched his hot skin Luke opened his eyes and smiled up at me.
