Summervacation with granddad

Emma, the 13 year old daughter, smiled as her parents told her she was being sent to her “Grandfather's” farm for the summer. Her parents were archeologists, and during the summers, when they weren't teaching, they usually went off to some far off place to dig up what Emma thought of as 'dead things'. And then Emma always got sent off to Grandfather's farm. Her parents had been working on their PhDs for the last two years, though, so it had been two years since she'd spent the summer with Grandfather. Grandfather wasn’ her real Grandfather but as her own grandfather had died before she was born, my mom’s cousin Chris had ben “adopted” as Emma’s Grandfather.
She was a little nervous about it this time. She'd always loved going to the farm. It was an old place, with lots of big barns and little outbuildings, and there were all kinds of interesting things to see and do. As she grew up, her Grandfather gave her chores to do, and each year they seemed harder, and seemed to take longer. But each time she left with a feeling that she could handle almost anything. She knew how to use all kinds of tools. She understood the needs of animals. She could drive a tractor and set a fence post all by herself. Now that she'd turned sixteen, she was curious as to what trials he would set for her this year. She was a little afraid that it might be harder than she could do.
But ... she'd get to spend time with Grandfather, who was her hero in many ways. Emma was what most people would call 'plain' looking. She had mousy brown hair that her mother liked to put into pigtails, and long bangs that almost covered her eyes.
She didn't mind that, though, because she liked the feeling that she was hiding behind them, looking out on the world which, for the most part, ignored her. She had been a skinny child, without much strength, and couldn't run fast, or climb trees quickly. When she rode her bike up a long hill she had to get off and walk halfway up, usually. She wasn't any good at baseball or other sports. And she had braces and wore big round owlish looking glasses.
As a result, she had few friends as a child. When she discovered reading in school, she found that books were her best friends, and she eventually gave up trying to find human ones. Grandfather was the one human outside her immediate family who treated her like a real person. He joked with her, teased her, asked for her opinion about things and generally treated her like she was already an adult.
It had been a particularly rough year for Emma. She'd gotten her braces off finally, but still hadn't retrained her lips, so she almost never smiled. Her breasts had endured a big growth spurt, which meant they had been sore and tender a lot. She'd never worn bras, mostly because she didn't have anything to put in them, but then, almost overnight, they grew to the size of grapefruits and wobbled around inside her shirt.
When she put on a bra it hurt her tender orbs. So she wore thick heavy clothing to hide her Bobbing boobs. When they quit hurting she was used to going braless and the loose clothes made that possible to keep doing.
Her hips had also swelled outward, but she thought that was a curse too because it just made her pants fit too tight. And that made it hard to put things in her pockets. Growing up was just a pain.
Having no friends to introduce her to boys, and being used to keeping her nose in a book, Emma entered the period of her life when hormones began flowing through her veins and she had no outlet to deal with them. She'd recently discovered that, during a bath or shower, there were some places on her body that felt really good to wash, but she hadn't thought out what to do about that, except maybe wash a little longer than was really needed to get clean.
So, Emma was looking forward to going to the farm for some reasons, and nervous about going to the farm for others. In other words, she had more in common with other teens her age than she thought. She was confused and unsure of herself.
Chris was taking a breather from wrestling with a recalcitrant bull when his brother drove into the yard. He'd been looking forward to seeing little Emma again. He didn't mind being alone on the farm most of the time, but she was such a breath of fresh air that it was a treat to have her around. She never complained about anything he asked her to do, no matter how dirty or hard the job was. She had a good attitude about everything and was smart as could be. And she was cute too.
Chris didn't have time to date women, and his sexual needs were pretty well satisfied by beating off from time to time. He had some pretty hot videos and ten or fifteen fuck books that he rotated through. He was afraid he wouldn't ever get around to having children to pass the farm on to, but there wasn't much he could do about that.
It wasn't hard, though, as Emma grew up, to fantasize about her. When she'd turned 13 she began to look more like a girl than a boy, and Chris's imagination took care of the rest. Of course she wasn’t a raving beauty or anything, but she more than made up for that because her insides, that part of her that was the REAL her, was beautiful and always had been.
Thinking about her now made his dick tingle. It had been two years since he'd seen her, and his imagination had made her into something he knew she probably wasn't.
The car stopped and the back door opened. A woman got out.
No, it was Emma!
But she LOOKED like a young woman. Chris couldn't believe what two short years had done to her boyish body. She had curves in all the right places.
She screamed out his name and came bounding across the yard, slamming into him in a bear hug. He felt soft breasts pressing against his chest and hugged her back. Her hair smelled good. She smiled up at him and he saw her braces were gone. Her smile was beautiful. His cock lurched in his pants.
Unconsciously he pressed his groin to hers and then backed off frantically, realizing what he was doing. He hoped she hadn't felt it.
His brother and sister-in-law stayed for dinner and then drove off on their way to the international airport. They'd be gone three months. Emma and her Grandfather were left alone in the old farmhouse.
It was May, and the planting hadn't started yet. Calves were due soon, but none were imminent. Chris had spent the winter repairing broken equipment. All in all, there wasn't that much for them to do for a week or two.
So Chris had planned on doing some home renovations, with Emma's help. When he told her about it she beamed and when he asked her what her opinion was about colors, fabrics and furniture, she blushed with the pleasure of being important. Chris opined that they should start with the spare room, which Emma always used when she was there. They planned and talked deep into the night and finally went to bed.
Chris jacked off, wondering what Emma looked like naked, now that she'd grown into a woman.
Emma, for her part, remembered how, when she hugged her Grandfather, she felt something pressing against her crotch. It had hit her right at the place where it felt really good to rub in the shower. She had suddenly realized what it was just as it was taken away.
Emma knew about sex. She'd had her first lessons right on this very farm, seeing the animals mating. And, of course there was the obligatory sex ed class in High School, though it was short on real detail. She knew the mechanics of it, but had never seen a human penis before. She'd never even thought about how big one would be until one had pressed against her crotch. As she went to sleep she wondered about what her Grandfather's penis might look like.
In the morning Emma bounded out of bed and put on a T shirt. She felt so comfortable at the farm she didn't even think of wearing her usual thick shapeless clothing. Jeans completed her outfit, though they were hard to get on over her recently swollen hips. She ran a brush through her hair and then tied it back in a pony tail so it wouldn't be in her face as they worked.
It didn't occur to her to look in the mirror before she went down to breakfast. If she'd looked, she might have changed clothes.
Chris was cooking eggs when Emma walked into the kitchen and sang out her morning greeting.
He turned to look and dropped the spatula.
Her T shirt had been white when new, but it was more cream colored now. It was thin from years of wear and her areolas and nipples showed through it. It was also a little small for her. It being May it was chilly, and her perky nipples had lengthened considerably, making obvious big dents in the material of her shirt. Her jeans were skin tight and, to get them up and over her hips, she'd had to pull them tight in the crotch. Her camel toe was as obvious as her nipples.
Chris bent over to get the spatula and didn't want to stand back up because he knew his now stiff cock would make a big hump in his jeans.
But he had no choice. He sighed. "Man oh man, Emma, you sure have grown up."
His comment caught her by surprise. Her Grandfather was staring at her chest. She looked down at the front of her shirt, expecting to see a stain or something, and saw her nipples. She blushed bright red and covered her breasts with her hands.
"Oh no!" she wailed. "I didn't think." A tear started to form in her eye.
Chris could see she was embarrassed. "Emma!" he said loudly.
She looked up at him timidly.
He went on. "Honey, you got nothing to be ashamed of. You're a beautiful young woman. You're in the prime of your life and it's only natural for you to look sexy. I'm just an old pervert to notice how desirable you are, that's all. It's really all my fault, honey, and I'm real sorry."
Emma stood there, her hands over her breasts. That wasn't helping Chris any. It just made her look even more sexy.
She sniffled. "Grandfather, I'm not sexy, I just look ... slutty," she moaned. "I didn't think about how I'd look when I put this shirt on. I don't dress like this at home Grandfather, honest."
"Well it's a good thing, honey" he said grinning. "You'd have the boys hanging all over the place with their tongues hanging out and their hands in their britches."
Emma's mouth fell open "You stop that right now!" she squeaked. "I'm embarrassed enough and you don't be needing to tell me lies like that. Boys don't ever look at me. I'm going to go change clothes."
She turned to leave.
"MAGS!" yelled her Grandfather.
She stopped.
He came up behind her and put his hands on her shoulders. He turned her around. He was standing close to her, close enough she could smell his manly scent.
"Emma, honey, I'm not making fun of you," he said seriously. He put his finger under her chin and lifted it until she had to look him eye to eye. "When I tell you you're beautiful, I mean it. When I tell you boys would kill to be near you dressed like that, I mean it. Heck, you gave ME a hard on!"
He stopped suddenly. He hadn't meant to say that.
"What I mean is, I'm not making fun of you at all. In fact, I'd like it a whole lot if you DIDN'T go change clothes. I don't get to see a sexy woman often, and you, little darlin', are one sexy woman." With that he hugged her to him, pressing those delightful breasts into his chest.
Her arms flew around him, hugging him tight and he let his boner lightly graze the front of her tight jeans. They held the hug for longer than usual, but it wasn’t uncomfortable because neither of them wanted it to end.
Finally he pushed her away. "Sweetie, I'm only a man. You can't rub that sexy body against me and nothing happen. And it ain't right for an Grandfather to have the kinds of feelings about his niece that I'm having right now. Besides, we've got work to do."
Emma didn't say anything. Her mind was running a mile a minute, thinking about all the things he'd said. She believed now that he'd meant them, and that was something completely new in her experience. No one had ever looked at her as a female, much less a desirable one. She liked the feeling ... a lot.
Emma didn't change her clothes. She caught Grandfather staring at her all day long and the hardon he'd mentioned was visible to her all day too. They got a lot of work done, but by the time the day was over both were horny, though Emma didn't recognize that feeling.
She liked the way her Grandfather looked at her. It made her feel squirmy inside. She'd always been able to talk to her Grandfather about anything, and she didn't think he'd mind if she did so now.
"Grandfather?" she said when they'd put away all the tools and were cleaning up at the kitchen sink.
"Yeah, baby?" he said, washing his big hands.
"Did you really get a ... hardon ... " she blushed as she said the word "because of me?"
Chris had been lusting after his niece all day long. As she worked he had stared at her loose boobs in their tightly confined T shirt. The thought of tweaking those stiff nipples and sucking on them until she spasmed was mouthwatering. And that sweet deep camel toe of hers, advertising her obviously virgin pussy.
Had he not been so hot for her, he might have moderated his answer, but instead he was bluntly honest. "Baby, you made me so hard today that sometimes it just plain hurt."
Emma thought about that. Instead of thinking of him as a dirty old man, she felt a thrill of pleasure that a real man found her desirable. She knew full well what that meant, but that didn't scare her either. She had no experience of any kind, and had no idea what "sex" might be like, so it wasn't scary or "bad" in her mind.
"So that means you want to have sex with me Grandfather?" she said innocently.
Chris sighed. He knew exactly how wrong he was to want his innocent niece. but he'd been leaking in his pants all day long. "Sweetie, you are so hot looking in that outfit that any man on earth would want to have sex with you. I'm sure no different than they are."
"Is it painful? I mean ... would it hurt if we ...?" she asked.
