Nancy woke late on Saturday morning. Nancy who just turned thirteen-years-old on Wednesday was glad that her cycle had ended the week before, for it only having been her second period, it was extremely hard on her. She was doubled over in pain almost every day and she still hadn’t settled into a normal cycle yet.
Nancy wondered why it was so quiet in the house, so she went looking for her family. Nancy’s mother Sue and her Father Chuck had went to the store leaving her fifteen-year-old brother George home to watch her.
Nancy searched all over the house and finally just as she was about to give up she heard some strange noises coming from George’s bedroom. Nancy hadn’t bothered to get dressed yet and was just in her little nightgown that barely covered her, Nancy needed a new nightgown since the ones she had were getting to be too small for her young budding body . Nancy stopped at George’s bedroom door and listened, to try and figure out what she was hearing. All Nancy could hear were grunts and moans and what she thought was the bed rattling and banging against the wall.
Nancy burst into the room thinking that George was having a fit of some kind, and she wanted to help if he needed any. What Nancy saw startled her so much that she stopped dead in her tracks. George was busy lying naked on his bed, with his hand pumping away at his groin. Nancy could plainly see George’s eleven and a half inch Dick sliding through his hand.
When Nancy realized what he was doing she screamed out at him that he shouldn’t be doing that. George quickly stopped and pulled the covers over his body and yelled at her, “ Why are you in my room without knocking?” Nancy was stunned and just stood there with her chest rising and falling quickly, her tiny nipples started to get hard and poke out through her nightgown. Nancy didn’t know why but her young Pussy was starting to tingle. George just stared at her and as he saw her nipples pushing out in her nightgown he thought to himself why not use her to get off.
George swung around and let his legs drop to the side of the bed as he went to stand up, letting his Dick pop out and stand at attention while he thought about her sexually for the first time. Nancy couldn’t move as George slowly walked towards her, she just kept looking at his big Dick. Nancy didn’t realize what his intentions were until it was too late. George was right there in front of her taking hold of her hand, he led her back to the bed and helped her to sit on it.
For the first time George could see his little sisters bare Pussy. George told Nancy that it didn’t seem fair that she was seeing him yet she was still dressed in her nightgown. Nancy protested that they shouldn’t be naked together since they were brother and sister. George didn’t listen to her protest and just grabbed the hem of her nightgown and raised it over her head. George could tell that Nancy was getting excited by the things they were doing and decided to take it a step further by rubbing her slick Pussy slit.
Nancy started to moan, and she was saying stop we shouldn’t, over and over again. George took her hand and placed it on his rock hard Dick and showed her how to rub it to make it feel better. The more George rubbed her slit the wider she spread her legs. George took this as a sign that she was willing to do what ever he wanted, so he pushed her over on the bed and lay down beside her. George started to rub Nancy’s budding breast, soon he was sucking on the right nipple. Nancy was still saying don’t while she was panting and moaning harder as the seconds passed.
George decided that now was the time to really start to stimulate her young Pussy, and pushed his finger into his sister’s slit going between the lips and finding her clit. Nancy stopped protesting his advances towards there incestuous play. George quickly found her opening and pushed his finger inside of her virgin Pussy. Nancy was so caught up in the feelings she was experiencing that she didn’t realize that George intended to go further until she felt his huge Dick pressing into her slit, as wet as she was George slipped right into the entrance of her virgin Pussy. George said god are you ever tight and wet, as he kept on rubbing her clit as he entered her. Nancy was too overwhelmed with sensations of pure lust and excitement to protest his violation of her virgin Pussy. Nancy started to push back against his thrust to help him get inside of her.
George started to pump in short thrust going deeper with each inward thrust. When he reached her Hymen George pulled out until just the head was inside of her and without any warning he slammed back into her tearing through her Hymen and burying three fourths of his Dick inside of her now no longer virgin Pussy. Nancy screamed out in pain and George stopped moving inside of her, They stayed like that for several minutes until Nancy could talk again and then she said we shouldn’t be doing this. George started to rub her clit again and she started to respond to his touches.
Soon they were both thrusting against each other in a good rhythm that had George going deeper into her until he was hitting her cervix and they were both feeling extreme pleasure from the copulation of there groins. George started to feel that special feeling in his balls that told him that he was about to cum, and although he knew that he shouldn’t cum inside of her he was too into the act to be able to stop and soon he was buried all the way inside of Nancy to the point that the head of his Dick was lodged inside of her womb when he started to shoot his load.
Nancy felt the first spurt hit the back of her uterus and she started to have her first Dick in Pussy Orgasm, after they both finished cumming they stopped and Nancy started to cry into George’s shoulder. George soothed her until he could ask what was wrong. Nancy’s reply was
“what if I get pregnant”.
George told her that he didn’t think that she could but that if they found that she had then he would help her figure out what to do. They lay together and fell asleep waking to find that George was hard again and still inside of her Pussy so they started to Fuck again until George let loose with another full load deep in Nancy’s uterus again. When they finished cumming again they got cleaned up and dressed before their parents got home. For the next four weeks George and Nancy would get together and Fuck whenever they were alone in the house and in the middle of the night when they were supposed to be sleeping.
At the end of the fourth week their mother Sue pulled Nancy aside and asked her if she was having any problems or if she had already had her period and it was just a mild one. That was the first time since her and George had made love that either of them thought about her periods again.
Eight months later Nancy gave birth to a beautiful baby girl and when her parents saw the baby they knew immediately who the father was and they just smiled at their children. Taking the baby home Chuck and Sue brought their children together and sat them down to talk. That night Nancy found out where George got his eleven and a half inch Dick as she got to feel Chuck’s thirteen inch Dick for the first time, while Sue got to feel George’s Dick inside of her Pussy.
