At birth she had been named Gennifer but had always gone by 'Jenny'. In high school Jenny had always been a popular enough girl. She'd dated a bit but nothing serious ever came about from those dalliances. Academically speaking she was mediocre and she wasn't really interested in going to college. After twelve years of compulsory education she'd had enough of school and instead opted for a nice enough job at a coffee place in Bozeman.
Her parents were fine with this choice. They weren't really the academic types themselves and hadn't complained when Jenny's older sister Leslie took a pass on the college and career path. To some degree they were relieved because paying for college wasn't really one of their goals in life.
When Leslie took a job at a local lumber mill it wasn't long before the divorced owner of the place asked her out on a date. Her long brown hair, comfortable demeanor, and her pleasant appearance captivated him. Despite the fifteen year age difference between them Leslie didn't hesitate when he took her to a fancy place one night and proposed.
The thirty-three year old Zack was successful in business but not so much in his first marriage which ended with a difficult divorce. His ex-wife had left him the six bedroom house and she moved away to Florida to escape the snow. He was a big man who had the look of someone who worked hard and who never needed to work out. He held his own in a business suit and he also wore his Carhartt's as if he were born in them.
Their wedding was modest as weddings went in rural Montana. Leslie wore the requisite white dress and deservedly so. There were friends, family, neighbors, and business associates in attendance and it was truly a lovely event.
It was later that night when Leslie discovered the full spectrum of Zack's ardor and passions. Although Leslie had talked about holding off on children for a while she discovered that Zack had no such plans. She had been caught up in the passion of her first sexual experience when Zack took her virginity and soon enough she accepted her first load of baby batter.
Their honeymoon was spent in a friend's place on the lake at Coeur D'Alene. It was a blur of romance and bare, unprotected sex and Leslie wasn't terribly surprised when soon enough she discovered she was pregnant. Zack was overjoyed at the news and that pleased his new bride.
The baby boy was born right as Jenny graduated from high school. Not having anything else to do she stayed with Zack and Leslie for a few weeks to help with the new baby and the big house. In that time she spent more than a little time sneaking glances at her sister's husband and admiring his rugged good looks.
In due time she went home and embarked on her new career in the coffee business.
When Jenny's nineteenth birthday came along Leslie couldn't attend the family dinner because the second pregnancy wasn't as easy as the first. Even though she was only in her first trimester Leslie was nauseous all the time and it was hard to function.
In one of those quirks of the universe a candle from Jenny's birthday cake hadn't quite been extinguished when it had been tossed into the kitchen garbage can. Hours later the diligent family dog woke everyone up and they escaped from the house and huddled together to watch their family home brightly burn in the night.
Jenny and Leslie's parents decided that the fire was their reason to retire and after the insurance issues were settled the two of them decamped for the warmer climate of Florida.
That left Jenny in need of a place to call home and of course her sister Leslie came to the rescue. Well, actually Leslie was laid up with complications from the pregnancy so it was Zack who helped Jenny get settled in at the house.
It was understood that Jenny would satisfy her rental obligations by handling her sister's duties about the house. Jenny had no problem with this and after quitting the coffee gig she did a fine full time job of juggling child care, laundry, shopping, and caring for pregnant Leslie.
Zack got used to seeing Jenny working around the house and taking care of her sister and the baby. As a particularly hot summer started in Jenny found herself going about her duties in a halter top and shorts. Zack couldn't help but stare at her long legs and trim body. Jenny would catch him staring at her and she misread it as Zack's disapproval of her efforts.
Jenny spoke to Leslie and Leslie just dismissed Jenny's concerns thinking it was work pressure and worries about the pregnancy that were bothering Zack.
Eventually Leslie took notice of Zack's attentions towards her younger sister and decided to confront him about it one evening.
"So you're checking out my sister quite a bit lately. What's that about?"
Zack shrugged. "She's cute, what can I say? You girls are something special and I don't mind looking at you."
Leslie's face scrunched up. "And nothing more? You're not going to fuck her?"
"Leslie!" complained Zack, "You're the only woman for me, baby! Can't blame a guy for looking at a pretty girl can you?"
"But it's crossed your mind, right?"
Zack was savvy enough to stop and think about what was being said. "Is this some sort of trap where no matter what I say I'll get in trouble?"
Leslie shook her head. "No, I guess I'm not going to blame you for looking when we haven't been able to do much lately with me sick all the time." She said this while caressing her baby-filled belly.
They changed the subject after that and talked about other things. What was ironic was that Zack had not consciously thought about Jenny in an improper way and now it seemed to be stuck in his head. It was also stuck in his head that his wife seemed to be encouraging him to pursue Jenny.
For her part Leslie found herself smiling later that night as she saw Zack eyeballing Jenny's legs again. Neither of them were aware that Leslie was harboring a bit of a kinky desire to see her husband and her sister together. Leslie felt guilty for having such a kink but at the same time the idea of her husband boinking the chaste and proper Jenny gave her chills. On balance she knew there was something a bit wrong about her kink but she embraced it anyway.
Over the years Leslie had harbored a love/hate relationship with her proper little sister. This grew when people had treated Leslie like a trophy wife for marrying the older and successful Zack. Those same people would gush and go on about Jenny's virtues and how she was 'one of those girls who will always do the right thing'. Leslie loved her sister but she also wanted to see her brought down a bit.
Thus Leslie started doing whatever she could to push things along between Zack and Jenny.
Her first effort was to get out of bed one day and keep company with Jenny while Jenny did the laundry. When Jenny put a load of her own things in the washing machine the sly Leslie reached over and switched the cold water to hot. The result was Jenny's clothes were now a tad smaller than before. This made Jenny's modest tits stand out more than before.
The next time it was putting too much bleach in with Jenny's panties. Jenny always used a touch of bleach with her panties to help keep down any bacteria but after Leslie got done with them they were always kind of itchy because they'd never been rinsed enough.
Then there were the sexually charged conversations she started having with Jenny. At first Jenny was shocked that her sister would talk about such things but then she did so in a mature way and it wasn't long before Jenny opened up about her own desires. Leslie enjoyed having gotten Jenny to discuss the notions of sex and Zack at the same time.
Leslie did some other clever things but the one that worked the best was the one she hadn't planned at all. One night she was getting into bed and she vomited all over the place! With the summer heat the smell of puke permeated the bedroom.
Jenny helped to clean it up and she made the bed afresh for Leslie while Leslie cleaned up. For his part Zack decided it was time to sleep in the living room. A little pissed off at the situation he got himself four fingers of whisky and drank it down.
It was well past midnight when Jenny decided to go to bed and having a raging headache she went to Leslie's medicine cabinet and found a brand name bottle of pain reliever. Blue pills. She took three of them and went to her bedroom.
With the hot night and the air conditioning on the fritz Jenny was uncomfortable to say the least. Add to that her itchy panties and she was fit to be tied! Getting up she closed her bedroom door, hesitated for a moment, slipped off her panties, and then lay down on her bed. Sleep hit her like a pickup truck.
Zack was restless on the couch. It had been months since the last time he'd been with his wife and as usual he was trying to sleep with a hard on. He thought about going to the bathroom to relieve himself in the sink but then his mind drifted to Jenny. He thought about her long legs. Her pleasing smile. Her perky little tits. The tight belly. Her delicate hands.
