It was in the spring of 1963, and I was living with my mother, step-father and two younger brothers. My step-father's daughter from a previous marriage decided that she no longer wanted to stay with her mother and would rather live with her dad. We picked her up with all of her belongings and she moved in. I had not seen Jenny in many years, since she was about 8 years old. She was now 19, a year younger than I, and she had filled out quite nicely. She was nothing spectacular like some you read about, but her breasts were about 34B's and she was proportioned just about right, standing about 5'4".
We hit it off right away and became good friends, almost like brother and sister. In fact, I would always introduce her to others as my sister even though she was, in reality, a step-sister. The only problem was that the house was not very large and did not afford much in the way of privacy for any of us. Mom and her husband had the main bedroom, and the other two bedrooms were very small. I had one and my two brothers had the other. I offered to give up my room to Jenny and take the couch, but that never happened. I adjusted the mirror on my dresser so that I would occasionally get a look at her in her underwear if I left the door open just a crack. She never wore slacks or jeans, usually dressing in a one-piece dress that buttoned up the front. Each night as she prepared for bed, I would watch her unbutton the dress and remove it, then she would pull her nightgown on and remove her underwear after she was covered by the nightgown.
We started taking walks in the evenings, after dinner was done and everything cleaned up. It was the only chance we got to talk, and my brothers were too young to get involved in some of our conversations, which soon began to involve sex. Jenny was 19, and still a virgin as her mother had watched over her like a hawk. That's why she wanted to move out. It turned out that her father was not much different. The only difference here was that he was a drunk, and he would go out for a few drinks and either cheat on my mom or come home, raise some hell and then pass out. I didn't get along with him at all because of this and the fact that, when I was younger, he used to beat the shit out of my mom. A few years later, he would try that again and I would kick his ass pretty bad. However, that was still years ahead and I'll stick with this story.
One night, Jenny and I were taking our usual walk. It began to get dark and we headed home. We took a shortcut through the alley behind the houses and stopped behind our house to talk some more. As the discussion got around to sex, we both began to get more daring. She mentioned that quite often while we were wrestling or goofing around, I would get a cheap feel and she had noticed it. I asked if it pissed her off or if she liked it. She said that she didn't mind. I moved my hand to her thigh and told her that she probably wanted this as much as me, but if not, just say so and I would stop. When she said nothing, I moved my hand higher up her thigh. She still said nothing, so I kept going until I found the crotch of her panties. They were damp and very warm. Her eyes were shut.
I rubbed her cunt through the material for a while, then got more daring as I moved the leg opening and slid a finger into her panties. I was now rubbing up and down her slit as her breathing got really fast. I threw caution to the wind and slid a finger as deep as I could into her hot cunt and she moaned. After a few minutes of this, her hand massaged my throbbing cock through my jeans. I unzipped my jeans, removed my cock and put it in her hand. She mentioned how big it was. My dick is about 8" and quite thick when it gets hard. That is slightly over average from what I hear. It was also throbbing, as I had not been laid in nearly a month. As Jenny stroked my big dick, I slid her panties to her knees and really began moving on her cunt in earnest. Pretty soon, we were both nearing an orgasm and I asked if she wanted it inside her. She said that she was afraid, and that she wanted to be virgin on her wedding night, but she was willing to complete things by hand. I figured fuck that, I could do that myself.
I dropped to my knees, lowered her panties completely off and buried my face into her crotch through her dress. She tried to back off, but her back was against the fence. I told her that I would eat her cunt and then, if she wanted, she could return the favor. She said that she had never done anything like this, and that it sounded gross. I told her to be patient, and that you never know if you like something or not until you try it. I didn't wait for a response. Instead, I raised her dress to her waist, getting my first look at her bush in the moonlight.
As my head moved closer, she pulled her dress back down. I stayed where I was and ran my hand back up to her pussy, now dripping wet, and slid a finger into her again. It didn't take long for her arousal to take over. I raised her dress again, and this time met no resistance. I buried my face in her pubic hair and blew gentle breaths, then finally slid my tongue up and down the slit, pausing at her swollen clit periodically. I would alternate licking her clit, then thrusting my tongue into her hot wet hole. Soon, she was thrusting her hips into my face as her orgasm approached rapidly. Her hands grabbed my head and she moaned loudly, then drenched my face with her juices as her first orgasm ever slammed into her and she nearly passed out. She was so weak that I had to help her walk about 10 feet to a wooden box, which she sat on until she could regain her composure.
I dropped my jeans and underwear and tried to take advantage of the moment and shove my dick into her. I was rubbing it into her slit and the lips were opening like petals of a flower. I shoved forward and the head of my cock began to enter. She stiffened and stopped me, saying that she was afraid. I told her that she could either do this or suck me off, but it would not be fair to leave me in my present state. She asked me not to come in her mouth. I assured her that it was not harmful, but I would try not to do that. I wasn't making any promises. She took my swollen cock in her tiny hand and stroked it, licking the head. I know she got a good tasted of pre-cum, which was flowing like crazy from the tip. She tried to suck my entire length into her mouth and gagged. This happened several times, as she was a bit awkward at this. After all, this was new to her.
Eventually she began to get the hang of it, and she was soon bobbing her head like a pro. She could only take a little over half of my length, but it felt like heaven to me. She would tenderly cup my balls in her hand and stroke the length of my shaft as her head continued bobbing up and down. I felt it coming very quickly, and didn't even have time to warn her. I'm not sure I would have warned her anyway. Suddenly my orgasm was upon me and the first spurt of thick, hot white fluid jetted from the tip of my dick and hit the back of Jenny's throat. Her eyes opened in surprise, and this spurt was followed by another, and another, and another, and another. Jenny gagged once or twice and had to swallow to keep from choking on the torrential flow of semen. It kept flowing as fast as she could swallow. I must have shot seven or eight thick jets of sperm into her mouth, and she had swallowed half of it. Some trickled down her chin from the corner of her mouth. Finally my dick stopped spurting and began to soften a little. It plopped out of her mouth, and she looked up into my eyes and swallowed the rest of my hot load.
I couldn't believe what had happened, and I think Jenny felt the same. We didn't mention it for the next day or so. Three nights later, we went for another walk, winding up behind the house in the alley again. We both felt a bit awkward, and I moved my hand under her dress. This time she stopped me, saying that, while she really enjoyed herself the other night, she could think of nothing else since. She was afraid that she wouldn't be able to control herself, and she didn't want to get pregnant. In fact, she still wanted to remain a virgin until marriage. Later, we were in my bedroom, sitting on the bed playing a card game with one of my younger brothers. The youngest brother had already gone to bed. Joe and Jenny sat on either end of the bed and I sat on the floor as the cards were laid out on the bed between us. I took the opportunity every once in a while to run my hand up and under Jenny's nightgown and slide a finger under her panties and into her cunt. We would exchange looks that hinted at things going further. This became almost a nightly routine for the next couple of weeks.
One night my mom and her husband went out for the evening with some friends. They all had children about the same age as my younger brothers, so Jenny and I stayed home. Now we had the house to ourselves. We were watching TV on the couch, and I moved closer to her, putting my hand on her leg. She looked at me and smiled, and I moved the hand under the hem of her dress and worked upward. Our manual stimulation each night had left both of us ready to explode, and I was more than ready to fuck my sister to oblivion. Her arousal was also quite evident, and I hoped she wouldn't stop me this time.
