Jenny was relaxing on the couch watching TV and feeling very sleepy after a long day in the sun. She was spending a few days at her Uncle's farm outside of town as she often did in the summer. As she had just turned 18 this was her last summer break before graduation. In his 30s, her uncle was handsome and well built and she had always felt comfortable visiting him, although his wife, her mother's sister, was a witch. She could never understand what he had seen in her and they didn't have any children either. Jenny wondered if they even had sex. As she lay there she found herself wondering how big his cock was and if he liked to fuck young girls with it. "Such naughty thoughts Jenny!" she told herself, but the just the idea of having sex with her uncle had made her panties a little damp.
She was wearing a cotton print dress with a button down front and had kicked off her shoes to lie on the couch while her uncle finished the chores. Her aunt was away visiting 'friends' she had said, and the house was quiet except for the sound of the TV. Her uncle had told her his wife had taken to visiting friends in the city several times a month, often staying overnight and sometimes he wondered if she was coming back. "Well, at least the house is peaceful with her gone" he had said. Jenny slid down and began to doze, her dress riding high up her thighs till it exposed her panties and she didn't bother to adjust it. She began dreaming about having sex in the shower with the stranger with his soapy hands caressing her breasts as his cock tried to find the entrance to her pussy. Then as it slid into her she was saying "oh John! Uncle John..."
Her uncle found her there sleeping when he came in. He noticed how grown up and sexy she looked lying spread out on the couch. Her breasts had filled out since the previous summer and made luscious mounds beneath the thin fabric of her dress. Perhaps it was just his imagination but there seemed to be two little bumps pushing out the fabric where her nipples would be. He found himself wondering what Jenny's naked breasts would look like and an image of her with her dress unbuttoned and her breasts exposed flashed through his mind. "Stop it!" he told himself, "she's just a girl", but the body laid out on the couch was clearly that of a sexy young woman, albeit one who happened to be his niece. He continued to gaze at her, noticing the way her dress was arranged around the womanly swell of her hips, he could see she was wearing tight pink panties that clearly outlined the mound of her pussy. He wondered if she had had sex before, or was still a virgin, and began to get a very uncomfortable hard on as he stared at her. She must be very tired he thought, and decided to carry her up to the guest room to put her to bed, as the sight of her lying there with her sexy legs and exposed panties was a recipe for trouble. His wife had been a cold fish in bed for the past few years and the sight of his sexy sleeping niece was very arousing.
He scooped her up in his strong tanned arms, one beneath her bare sexy thighs and the other beneath her arms. She murmured something sleepily and put her arms around his neck, pressing her breasts against his chest and resting her head on his shoulder as he carried her up the stairs. Her dress had ridden up to her waist fully exposing her panties and his dick had extended down his pant leg and was throbbing against his thigh.
He entered the darkened room, and laying her gently on the bed, he leaned over to kiss her cheek. As he did so her hand, which had been draped over the side of the bed, came into contact with the lump in his pant leg. Somehow he found her lips instead of her cheek and as he kissed her he felt her fingers slide up the length of his imprisoned shaft and back down before wrapping around it and giving it a squeeze. Startled, he stood there in the dark as Jenny's hand began to massage and squeeze him. Before he knew it she had rolled over toward him and her hands were fumbling with his belt and unzipping his fly. In a minute she had his bare cock in her hand and was stroking its turgid length.
"Mmmmmm you have such a big one Uncle John, it's so thick and long and hard, I was so hoping you had a nice one!" she whispered.
Then he felt her tongue on the tip, licking the sensitive skin and kissing it before enclosing the fat head between her lips. The sensation was wonderful. He hadn't had his cock sucked in years and Jenny seemed to have considerable experience. His eyes clouded over and he groaned softly
"Jenny, what are you doing?"
"Kissing you goodnight uncle John." came the whispered answer and then her lips resumed their task.
His eyes had become adjusted to the dim light and he could see that she had a hand between her legs and was rubbing her pussy as she sucked while her other hand was still wrapped around his shaft, stroking it gently in perfect rhythm with her sucking. Her lack of shyness and quick evaluation of his equipment suggested she wasn't a virgin and the pleasure she was giving him with her mouth made him lust for more. He was quickly losing control of his desire. As if it had a will of its own his right hand reached for Jenny's naked thigh.
When Jenny felt her uncles hand on her upper thigh she knew she had him. She stopped rubbing herself and let his fingers slide up and explore her panties. She moaned softly as she felt them slide beneath the waistband and down through the patch of pubic hair to find the opening between her legs, already slick with her excitement. She moaned again and spread her legs wide, inviting him to mount her. His cock was long and thick with a large bulging head and she couldn't wait to feel it push its way between the folds of fatty skin that surrounded the entrance to her pussy.
"I want you Uncle John!"
Her whispered words were like a drug. Overcome with lust, his desire to plunge his aching erection into the warm, moist opening between Jenny's legs overwhelmed his last shreds of reluctance. He no longer saw his niece on the bed, but a young women with a luscious mouth and enticing breasts, her legs spread, waiting for a man to come between them. "I can pull out before I come" he thought, and stepping back from her he quickly removed his clothes before climbing onto the bed. He leaned over, and putting his hands on the mounds of her breasts, kissed her full on the mouth before climbing between her legs. She could see his erection waving between his thighs as he prepared to fill her waiting cunt.
"Please!" she said, "Please put it inside me Uncle John, I need to feel it inside me!"
Pulling aside her panties and placing the head against her opening he pushed into her. She was so wet that he slid in easily, despite the tightness of her pussy.
"Yes!" she cried out, "Oh god you feel so good! Fuck me now, oh god, please fuck me!" she moaned, thrusting her hips up toward him as he began to stroke in and out.
"Kiss my titties while you fuck me!" she begged, unbuttoning the front of her dress and pulling a bra cup aside to expose a nipple for him.
He lowered his lips to her breast, sucking on the hard nipple and massaging the other breast as he thrust his dick in and out of her with growing excitement. Jenny's tight pussy and lustful desire was causing him to lose control and he knew if he didn't withdraw soon he would flood the girl's cunt with his sperm. But Jenny had no intention of letting him escape without cumming inside her, and she wrapped her legs around him and urged him on as she felt his dick stiffen and swell, recognizing what was about to happen.
"Yes!" she moaned, "Yes do it now, cum inside me, shoot your stuff inside my pussy!"
Then it was too late. He groaned and his cock began to jerk and spasm wildly, shooting out thick jets of semen with such force that Jenny cried out and clutched at him as his pulsing cock filled her with his seed.
"Oh god Jenny! OH GOD!!" he groaned, startled by the intensity of his orgasm.
He lay on top of her, holding her tightly as his cock continued to pulse within her. He hadn't come like that in years and was basking in the sensation, hardly thinking of the consequences of what he had just done. Slowly the realization that he had had sex with his niece, that he had come inside her, possibly impregnating her, began to grow. Surprisingly, instead of causing anxiety, he found the notion incredibly pleasing and erotic. After years of trying with his wife he had given up the notion of fathering a child. Now here he was with his penis inside the pussy of a fertile young girl that he had just filled with his semen who seemed to share his desire.
"Sleep with me." she cooed, her hands lightly rubbing his back "Sleep with your cock inside my pussy. I want to feel you inside me all night."
"Oh Jenny honey, oh baby, my sweet baby!" was his response as he kissed her and nuzzled her face.
Jenny fell asleep in his arms feeling completely content and satisfied. While she had fantasized about having sex with her uncle mainly out of general horniness, the feeling of satisfaction when her uncle's large cock entered her for the first time, the pleasure of feeling him thrusting inside her, and the sense of fulfillment when his sperm laden cum flooded into her pussy and he had called her name had given her the most intense orgasm she had ever felt. As she dozed off she remembered that her last period had ended about ten days ago and she wondered if her body had unconsciously recognized the opportunity her uncle represented and fueled her desire for sex with him.
John woke up to the feeling of Jenny's hand stroking his morning hard on. She had removed her panties and when she realized he was awake she climbed on top of him and straddling his thighs she placed the tip of his erection at the entrance to her pussy and eased down onto it, her warm cunt enveloping his shaft, and she began to rock up and down, moaning and sighing in pleasure. His hands found her breasts and caressed and squeezed them till his dick began spurting inside her again. Any remaining doubts about the wisdom of having sex with his niece seemed to have completely vanished during the night and he savored the sensation as his cum flooded Jenny's pussy again.
She laid down on top of him with his dick still inside her and told him she had him to herself for three whole days and she expected him to take advantage of her as often as he wanted. His cock was the perfect size for her and the way he held her and kissed her made her feel like a woman, his woman. She hugged him again, pressing her breasts against his chest, and told him she would have breakfast ready for him when he had finished the chores.
