My Horny, Pregnant Sister

My sister Christine became pregnant when she was 19-I was 24 at the time. Since her husband was away a lot with his job, she came to stay with me and our mom while he was out of town for his work so that she wouldn't have to be alone. Not too long after she got pregnant, her sex drive absolutely went through the roof. She was literally horny almost all the time. The first time I realized this was shortly after she came to stay with us. I walked into our room and Christine was standing with her butt resting against the dresser, completely naked, rubbing her clit furiously, with a desperate look on her face, completely oblivious to the fact that I was there or that the door was open. I stood and watched her, partly in shock that she would do this so openly, and partly mesmerized by how erotic it was. She only partly opened her eyes to look at me and continued to rub her clit back and forth very fast. Her stomach had just started to grow, and her long, dirty-blonde hair flowed down over her rather large boobs, her erect nipples sticking through her hair. Even though she was and is a little heavy-set, as opposed to my skinniness, she is actually quite attractive. She suddenly closed her eyes very tight and began to groan from way, deep in her chest-her legs tightened up and she mashed her fingers down into the top part of her crotch as she let out this animalistic groan that almost seem to come from her stomach. I couldn't take it any more and had to go and privately masturbate as the sight of her doing that made me extremely horny, and I needed to feel myself orgasm to get rid of the ache in my clit. She later apologized and said that since she had got pregnant, that she just felt incessantly horny, and she just didn't know what had gotten over her. She said that getting and being pregnant made her feel so womanly and horny. I told her that was ok, that I thought I understood. I would walk by our bathroom sometimes and she would be sitting on the commode with the door open, rubbing herself like mad with that desperate look on her face. I really felt the need to rub my crotch as I saw her, but was too shy to do so. We slept on separate beds in the same room, and I would be awakened by the sloshing noise of her driving her fingers into her wet vagina and mumbling, or the swishing noise of her wetness as she rubbed her clit like mad and moaned. I finally gave in to my own horniness as I watched her, and turned over on my side and rubbed myself to an orgasm as I watched her do that, although I tried not to moan as my orgasm started. One night I was asleep, and was awakened by Christine thrusting her fingers deep in to her vagina, and mumbling, 'that's it, give it to me, drive it in, tear it up...'. That was just a little too erotic for me, as she had the covers off and I could clearly see her thrusting her fingers into her pussy as she raised her pelvis to meet the thrusts. I got out of my bed and went and laid down on my side right next to her. I had on a bra with a tight t-shirt over it and my panties. I scooted right up next to her and raised her shirt-she was not wearing a bra-and I began to suck hard on her right nipple. I sucked and sucked and she began to moan loudly, and she took her fingertips and mashed down on the area around her nipple, then touched my lips with them and then put her fingers in my mouth to feel my tongue as it licked her nipple, as she fucked herself with her other hand. She then reached inside my shirt and up into my bra and found my nipple and scratched it deeply with her thumbnail-the way she did it was so intensely pleasurable that it immediately made my belly begin to heave with an orgasm, even though I wasn't even touching myself. I felt the orgasm start deep in my stomach and it bucked up and down as strong contractions gripped me. She groaned real deeply as she came just after that and we feel asleep in the same bed, pretty much exhausted. A few days later I came in our room and Christine was leaning up against the wall, rubbing her clit like mad again-this time I bent down and took her breast in my hand and began to suck and chew hard on it, which made her moan and seemed to hasten her orgasm-I unzipped my jeans to get into them and rubbed my clit so that I orgasmed right at the same time she did. I initially felt guilty about sucking my own sister's boobs, but it seemed to make her orgasm start quicker and her orgasm seemed deeper and more satisfying if I was chewing on her nipples as she came-it seemed to help her sleep and be a little less horny, and I honestly enjoyed it a lot. A few times I thought about putting my head between her legs and lifting her clit hood and licking her to an orgasm, but thought that really was a little too kinky. A few times, though, when she was really horny, I sat up on the bed and told her to spread her legs, and I rubbed the shaft of her clitoris back and forth with my fingers until she went into orgasm. Her clit was somewhat larger and longer than mine, and when I rubbed the shaft back and forth, the large head of her clit kind of 'snapped' if I pressed down fairly hard, which always made her moan loudly as I did. I had never felt another clitoris other than my own, and it was so sexy to feel hers in comparison to mine. I would tangle my fingers up in her hair with my other hand as I rubbed her clitoral shaft back and forth to cause her to have an orgasm. A couple of times during her pregnancy, her husband came home, so she went to stay with him for a few days while he was in town. She would come back and tell me how good the sex was as she begged him to fuck her as hard as possible. She also had a strong desire to feel him ejaculate as much semen inside of her over and over, to feel her belly filled with as much as he could shoot into her. She would describe all the details of their fucking, and we would bring ourselves off in our beds talking about it. The last time that he came home and fucked her during her pregnancy, she made a video of their fucking, which we later watched together and masturbated to. It was beautiful to watch my brother-in law's cock drive into her pussy, and the passionate fucking that they did. He never had a clue that I had seen the video, and she made several more a while after the baby was born that she let me keep, and that I particularly love to jill off to. My sister and I are certainly closer now than we were before, I think in a good way. She calmed down some sexually after the baby was born, but it looks like she's pregnant again-so I guess it's gonna be another horny 9 months!
