Let me tell you about my sister-in-law. When I was dating her older sister, about ten years ago, I didn’t pay much attention to Marianne. She was a geeky, gangly nineteen year old, about 5’9” with a lean, almost skinny, body with long arms and legs and hardly any breasts to speak of. Her hair was very short cropped and varied between sandy blonde in the summer and mousy brown in the winter. A long, thin, small face graced with high cheekbones and a long, pointed nose. Small blue eyes in narrow eye slits gave the impression that she was always squinting although these were made larger by the cheap glasses that she wore that seemed to add to her mousy image. A narrow, pointed jaw seemed to exaggerate her small mouth and thin lips, making it look like she had too many teeth. Despite her gangly arms and legs, she had relatively large hands and feet on the ends of them - size eight feet and long slender hands with long slim fingers. As I have already said, she was a bit geeky looking – small face, long nose, narrow jaw and a small mouth with too many teeth. She was the sort of girl that men wouldn’t usually give a second glance to, however she was a pleasant young woman and easy to get along with. Wearing jeans, t-shirts and baggy jumpers didn’t particularly help either.

Leaving school early due to bullying about her looks, she took up farm work -milking cows, collecting eggs, that sort of thing. She cycled almost three miles to work daily along a busy dual-carriageway - quite perilous and not the sort of thing I would be brave enough to do.

After I got more serious with her sister, Marianne seemed to feel left out in some way and started going out with Kurt for fear of being “left on the shelf.” Kurt was trouble, a tall, lanky, cocky young man who could never hold down a full-time job. He was a loud-mouthed racist who liked making up excuses to beat up innocent Pakistanis or Indians. (“‘ere you’ve picked my parking space!” Thump! “Oi! You were looking up my girlfriend’s skirt.” Wallop!, etc.) Nobody approved of Kurt and even I didn’t think he was suitable for Marianne. He thought nothing of shoplifting or stealing and was always getting into trouble with the police. Then he got her pregnant and pressure from both his family and my in-laws forced them to get married.

Kurt went through a number of menial full-time jobs, which never lasted more than a few months at most. In truth, he didn’t like being told what to do and decided to be self-employed. His main job was as a window cleaner supplemented by a series of unsuccessful ventures such as selling goods at open air markets or car boot sales. He fiddled his tax and lived mainly off social benefit. Most of the time he spent sitting at home, watching satellite TV (with a pirated smart card) too lazy to go out and do any work.

Kurt came from a long tradition of large families where ten or eleven children were not unheard of. He turned Marianne into a baby producing machine, despite the fact that they didn’t have the finances to support them. After having four kids, she put her foot down and told him that enough was enough.

One of the benefits motherhood gave Marianne was that she put on more weight. Her skinny, gangly body became tall and slender. Her face filled out. This made her look more attractive; though still a bit geeky looking at first glance. The short hair and glasses now suited her (better looking glasses making her small blue eyes larger and more appealing.) Pigeon breasts filled out to a pleasing 36” chest which was very apparent because she often did not wear a bra letting them bounce around as she walked. On one occasion I was helping her adjust a wheel on a kid’s bike. I was kneeling down, working on the wheel, when she bent over in front of me to pass me a spanner. Unfortunately for her, she was wearing a loose top and, when I looked up to take the spanner from her, I found myself looking down the front of her top at a nice pair of dangling breasts and her nipples. I was too surprised to look away and gawked at the pleasant display. She didn’t seem to notice, yet that image kept replaying itself in my mind for weeks afterwards. That’s when I really noticed how attractive her body had become.

The next thing to catch my attention, and her best asset by far, were her long legs which I noticed had become rather shapely and sexy. There was slight muscularity in her calves with good muscle tone that was particularly evident when she wore high heels, climbed stairs or stepped over baby gates. At Kurt’s insistence she took to wearing short mini skirts or skin tight leggings that really showed off her fantastic legs and gave me plenty of opportunity for admiration and secret longing.

Then one day, some bastard broke into my office during the daytime whilst I was out and attempted to rape Marianne. Luckily she managed to fight him off, kneeing him in the groin before getting away. However the event had unsettled her and she was very upset. In a way I felt responsible because it was my office that the guy had broken into and if it hadn’t been for that, then Marianne wouldn’t have been attacked.

I visited her quite a bit following the attack, trying to reassure her and wanting to make up in some way. She told me that she was scared of going out now, even in daylight. I suggested to her that she should perhaps take self-defence lessons which would not only help her defend herself if some creep tried again in the future. But that it would also help boost her self-confidence. She didn’t seem too keen at first, but I persisted thinking it was a good idea. Finally she agreed, but Kurt didn’t like it saying that he could teach her himself having recently taken up jujitsu (so he could beat up bigger Asians!) Marianne didn’t like his idea and I had to agree that she would be better off being trained properly by qualified instructors. Miffed, Kurt refused to pay for her to take any lessons. Still feeling somehow responsible, I promised Marianne to pay for her course as an early Christmas present (three months early in fact!) The fact that the idea of my sexy legged, though slightly geeky looking sister-in-law becoming a man destroying Amazon appealed to me was also a deciding factor! Marianne wrapped her long arms around my neck and gave me a long kiss of thanks with her small but kissable mouth that aroused feelings down below. Luckily, Kurt was not around to notice.

A few days later, she came around the office to see me with the details of the course she had found. I met her at the door and she entered wearing a short blue jacket, matching mini skirt, thick black tights and high heeled shoes. My office is actually over a Chinese take-away, so as she climbed up the stairs that led to the first floor where my office space was, I followed gazing lustfully at the way her calves bulged and the slight shapeliness of her hams. At the top of the stairs, she bent down to remove her shoes to rest her feet. I’m afraid all I could do was stand there, unable to tear my eyes away from the back of her legs and the short skirt rising up towards her small firm backside. Finally she stood up straight and walked over to the old sofa I had brought from home to make clients feel more comfortable. As she did so, I noticed the slight bulge of slender muscles running up the outside of her slender legs. Then she sat down on the sofa, her short skirt riding up as she sat back and stretched out her long legs. Trying unsuccessfully not to keep staring at the vast amount of leg on show, I sat next to her and listened as she told me that she had found a course at a nearby town. The only thing was that it ran for two ten-week terms, twice as long as all the other courses offered elsewhere. “I want the best. Please, Jim,” she begged. How could I refuse, with those long legs turning me on? Taking a chance I put my hand on her thigh, getting excited at how firm it felt. “Of course, Marianne, for you I’ll do anything, I said. She gave me quite a long lingering kiss of thanks that stirred things that really oughtn’t. That was nearly three months ago.
