A fantasy story – all participants are over 18 years of age.
It was on my 18th birthday, and I was still at school when we had our first sexual encounter.
Susie my older sister, was 19 years old, and worked at our local post office.
Dad was employed by a well known insurance company, and worked in one of their London offices.
My Mum had some kind of desk job at the local council offices. Both Mum and Dad worked the usual 40 hour, 5 day week, but Dad in particular, spent a good part of his day commuting.
Susie would have been about 5' 5'' tall, and I guess, about 140 lbs in weight. She had naturally dark brown, shoulder length hair, blue eyes, and very pale skin. Her breasts were quite large with prominent nipples. She had the most gorgeous bum, and very nice legs. As I found out later, her pussy mound was quite prominent, with just a very small amount of pubic hair at the top, which she always kept very well trimmed. Her pussy lips were smooth, and pale pinkish in colour. To be honest with you, I thought that my sister was the most beautiful woman on earth, but then I guess I was biased. When it came to clothes, Susie was very 'Girlish', preferring dresses to jeans. Especially during the summer months, when she used to take great pleasure, much to my delight, in wearing very low cut dresses, that did nothing to hide the curve of her breasts. They were often only mini length, which afforded a great view of her bare legs. She would wear as little as possible around the house, especially when our parents weren't around. More often than not, she would prance around in just a bathrobe, and sometimes in just her bra and panties. Mum was forever telling her off for behaving like "some kind of cheap slut"!
I was about an inch taller than Susie, and perhaps a little slimmer. Nothing out of the ordinary, in fact I was quite plain. I had the same coloured, shoulder length hair, and also blue eyes. My cock wasn't much to write home about...maybe about 6" long when fully erect, but quite thick. (At least, that what Susie said). I was usually in either jeans and tee shirt, or if the weather was really hot, then I'd be in my shorts. I had been fantasising about my sister for a few years. In fact, ever since I'd discovered the joys of masturbation. I'd had many a wank, just trying to imagine what Susie looked like naked..... Were her tits as big as they looked? Was her bum really as juicy as I had imagined?
One hot, sunny day near the end of July, I was on school summer holiday, and Susie had just started a two week break from her job. I guess it must have been about 11 a.m. Mum and dad were at work, and I thought that my sister had gone out, because I hadn't seen or heard anything of her. I was inside our shed, deeply engrossed in one of my dad's well worn porno magazines which he kept hidden, or so he thought, in an old chest. I had been wanking furiously for some time, when I sensed that I was being watched. I glanced sideways and had the shock of my life to see my sister's face pressed against the window. I started to panic, trying to hide my cock from my sister's gaze, but I knew that it was too late. She shouted for me to let her in. All I could do was to stand there, with my head hung low, ............... my shorts halfway down my legs, and my cock standing upright, swollen and rigid, as Susie read me the 'riot act'. She called me a "dirty little bugger". Said that I should be "ashamed of myself", and that "I should find something better to do.........like homework for example!"
I burst into tears, and kept saying how sorry I was. I begged her not to tell anybody...not a soul. I told her that I would do anything she wanted ......... anything at all. I must have spent a good ten minutes, 'signing' my life away. Of course, I was too young, and far too naive, to realise that she was enjoying every minute of my torture and humiliation. The cruel bitch just stood there with her arms folded, and let me rave on, and on!
Susie eventually forgave me, promised not to tell anybody what she had just witnessed, and to my astonishment, openly encouraged me to finish my wank right in front of her, there and then.
That eventually progressed to watching each other masturbate, then doing it to each other. I would be finger-fucking her pussy while she rubbed my cock. We took almost every chance we had to have bodily contact. Regardless of the consequences and the risks of getting caught; we had episodes in our bedrooms, the bathroom, the kitchen, and even the garden shed.
Those few weeks were like one long orgy. Susie loved to have me watch her fuck herself with all kinds of different objects, such as fruit, vegetables, candles, and a hairbrush handle, while I stood in front of her, tugging at my cock for all it was worth, and mouthing the 'dirty' words that I knew she loved to hear.
We had been having this sexual contact often, at times and in places, where we ran the risk of getting caught. Susie claimed that the risks made it all the more enjoyable. I had to agree with her on that score! On several occasions, my sister had mentioned that she'd like us to do something really outrageous and risky one day, and promised me a big surprise!
One night, Susie and I were in the lounge with Mum and Dad, watching "News at Ten". My sister was wearing her usual bathrobe, and I was in pyjamas and dressing gown. Mum and Dad sat in the armchairs, while Susie and I shared the couch. When the advert break started, our parents went to the kitchen to make their bedtime chocolate drinks. Susie didn't share their taste in nightcaps, and had just downed her third vodka and orange.
"I've got a treat for you little brother" She said, as she stroked the top of my leg. I asked her what she had planned, but she told me that I'd just have to be patient, and I'd soon find out.
Mum and dad returned with their drinks, and stayed with us until the news ended, before saying goodnight, and going up to bed.
