When I was 17 my grandad took ill and after a short illness passed away leaving my gran widowed and alone. she came to stay with us for a while and after a few weeks she said it was time for her to return home. gran lived at the other side of town in a big old house, a bit creepy really. the day she was due to go home my mum pulled to one side and said that gran wasn't looking forward to being in the house by herself and said I would be doing both gran and herself a huge favour if I would go and stay with her for a while, just until she could get used to the idea of being on her own. I didn't take much persusion, I loved my old gran so much and she was always really good to me, she often told me that I was her favourite grandchild, and there were fifteen of us so that always made me feel very special.

 So for the next few weeks I lived with gran, only occasionally going home to see mum and dad or if I needed anything from home. although it was quite a big house, it only had two bedrooms which were both very large and were connected by an adjoining door, one night, it was Friday, I hadn.t been in bed all that long and I had just heard gran go to her's when the adjoining door opened and gran walked in, "are you still awake", "yes gran","I was just wondering if you would go in to town with me to morrow, I need a few things but don't really fancy going myself", "that's ok gran, I'm not doing anything to morrow and I would love to go to town with you", "oh thank you Charles, sweet dreams". as she turned back to her room the light coming through the window caught her and just for a second I could see the shape of her body through her nightie, no I thought, I felt myself being sexually aroused by what I had just seen, my old gran, at the time I didn't know how old she was, I now know she was sixty nine and I had a raging hard on after seeing her with her nightie on. gran was like most other women of her age, short, carrying a few pounds more than she should, grey, almost white hair and slightly stooped. as for me, well I was still very much untouched, I had never had a girlfreind, to be honest had never really fancied any girl, at the time I thought there might be something wrong with me because it was always older women that turned me on, none as old as my gran though, my freind's mum, a few of my ex school teachers and one of the ladies in the office where I just started working, but none of them had made me feel as horny as I was feeling right now, I began rubbing my rock hard throbbing cock and in no time at all I was having the most powerfull and intense orgasm I had ever had, I tried to catch the spunk with my hand but it was no use, what a mess, I cleaned it up with my underpants the best I could. what will gran think when she see's this.
