I was a young writer and teaching classes at the local university at the time my older sister Christine finally broke up with her no-good fiancé. There was just one problem: in order to get away from the jerk, Chris had to move out of their house, paid for almost entirely by her. Since she lived in the same city where I attended grad school she dropped by my place to get my advice on what she might do.
"Why don't you move in here for a while?" I asked, trying to be helpful. "I have the spare bedroom and I live a pretty quiet life."
"Are you sure?" she asked, probably hoping I would suggest just that.
"Of course."
"But you'll have to give up your study room."
"It's okay. I can work damn near anywhere. Come on, it's settled. And after we get things situated we can go get some pizza later to celebrate your new freedom!"
"You know, Scott, I feel better already!"
"I thought you might."
During the ensuing weeks we settled into a cozy domestic routine. Chris went to work every day as a schoolteacher, and I went about the business of working on my first book.
It was great having Chrissie around because she readily pitched in to help with the housework and cooking. We even found time in our busy schedules to have a nice dinner at home a few times a week. Although my (our) apartment has only one bathroom, we never experienced any friction over it, or anything else for that matter.
There was just one little problem.
The more time I spent around Chris, the more I began to notice her physically. A petite blond with entrancing blue-green eyes, Chris has a vivacious personality that draws men to her like moths to a flame. She has an outdoorsy appearance with excellent color to her face, a few freckles around her nose, and an inviting figure. She still looks great in a bikini. Chris is also intelligent and witty, and able to engage anyone in clever repartee that is inherently attractive.
One night at dinner Chrissie raised an interesting subject. "You know we've been living together for three months and I haven't seen you bring one girl home, or even go out on a date. I hope I'm not cramping your style."
"Not at all," I replied, taking a bite of her delicious pasta primavera. "It's just that I'm really focused on my work and I don't want to short-change a relationship with it being the priority."
"Still, it's hard to believe someone with your looks and personality could escape at least temporary capture from a girl."
I responded with an embarrassed smile.
"Well, I don't know about that, but it isn't you, be sure of it." She smiled and continued eating. "I notice you've not been entertaining any gentlemen callers?"
"Oh, well, I think I need a break. If it weren't for sex I would probably swear off men for a long time."
I was taken aback by her point-blank admission of the need for sexual gratification, but I let it pass. Nevertheless, I started to find myself strangely attracted to Chris. I thought it might be my imagination, or it could have been the glorious spring weather, but Chrissie started to take a more relaxed approach to her wardrobe around the apartment. Her jeans and sweaters were replaced by short silk running shorts and tank tops with spaghetti straps. And even more significantly, she started to leave the bathroom door slightly ajar when she was in the shower.
The clincher was when I happened to walk by her bedroom one day and notice the door cracked slightly. Curious, I discreetly peered in through the crack and saw Chrissie on the bed, sunlight from the window pouring over her naked body while she worked a dildo in and out of her pussy. She was biting her lower lip trying to suppress her erotic moaning, but a few sounds escaped as her breathing and motions quickened. Her nipples protruded up at least a half inch, and her reddish brown pubic hair was moist with her excitement.
Then suddenly she stiffened and trembled all over as she came, closing her eyes tight and then opening them wide as if surprised at the intensity of her climax. Her legs spread even further apart and flailed as if subjected to powerful electric current.
"Oh fuck!" she gasped, as quietly as she could, and then she came down on the other side, her body twitching at regular intervals as the waves of her orgasm subsided. Removing the dildo from her pussy, she pulled the soft cotton top sheet over her glistening naked body and rolled over to rest.
When I came out of my trance, I realized that my cock was stiff as a flagpole and without realizing it I had come in my shorts. I rushed on to my bedroom, quietly shut the door, then quickly cleaned up and changed.
To pretend as if nothing happened I lay down on my bed and picked up a book resting on the nightstand and began to read, but I couldn't concentrate on the words. After reading the same sentence six times I realized that all I could think about was how sexy Chris looked during her solitary session and how turned on I had been.
In a few moments there was a gentle knock on my door.
"Come in."
Chrissie opened the door, wearing her short summer weight bathrobe.
"Hey," she said casually. "Getting some reading done?"
"Sort of, but this book isn't very well written. It's a real slog getting through it."
She smiled, patting me encouragingly on the thigh.
"You'll do fine. You're the brilliant one in the family. Well, if you're not going to need the bathroom for a few minutes I'm going to jump in the shower."
"Not a problem," I replied, turning back to my book. I hoped I came across more casual than I felt.
After I heard the sound of the water running in the shower I was tempted to see if I could get a peek of Chris naked again, this time glistening wet and rubbing soap all over her taut body. But I resisted the urge, for some reason, and the day ended without further incident.
In May, school let out for me, followed a couple of weeks later for Chrissie. My summer meant a lot of writing of my own and a chance to catch up on reading. Chris has summers off, so she takes advantage of her freedom by playing a regular tennis game with one of her teacher friends, and working on her tan by the pool of our apartment complex. However, I found myself becoming more and more fixated on my sweet and sexy sister.
With no effort Chrissie can be very flirtatious, and she's a very outgoing, affectionate person. As a result, I was frequently the recipient of hugs from her, which I thought at the time were probably intended as nothing more than appreciation on her part, but would send naughty signals to my cock that were anything but familial.
I grew bolder in my attempts to watch her masturbating and taking showers. Seeing her naked was an incredible turn on for me, and the taboo nature of what I was doing seemed to heighten my arousal. After watching her get off I would quickly adjourn to my bedroom, quietly lock the door, and jerk myself to an incredible climax thinking about Chrissie's hot body. My fantasies about her were growing more frequent and more elaborate.
One Saturday morning in June we were at the breakfast table eating when Chris asked me if I had any plans for the evening. I did not, and she suggested it would be fun to have a movie night, just the two of us. I thought that sounded fine, told her to pick something we both would enjoy and I would get some takeout Chinese.
We spent a relaxing evening sitting on the couch and watching a comedy. Then something strange happened. After the movie I was sort of mindlessly flipping through the cable channels when I happened to come across a soft-core adult feature. I started to quickly go to the next channel when Chris grabbed my arm.
"Wait a minute," she said, laughing. "Go back to that and let's see what it's about."
I flipped back and on the screen was an attractive young couple having sex on a pleasure boat. The woman, a buxom blond, grabbed onto the ladder leading to the upper deck and her partner was standing behind her, ramming it home and massaging her tits. We could hear their moaning and groaning over the soundtrack.
Under normal circumstances this is the kind of movie I would be happy to check out, but I was pretty self-conscious to be watching it with my sister. Chrissie didn't seem fazed at all.
"This isn't making you nervous, is it, Scott?" She asked slyly.
"No, not at all," I replied sarcastically. "Why would I be nervous about watching a porno with my sister?"
Chris laughed, seeming to enjoy my unease.
"Oh, come on!" she replied. "Don't be such a prude. We're both adults. Besides, I think these kinds of movies can be funny."
"You mean as long as the principal at your school doesn't find out."
"Well, I'm sure you're not going to tell her, are you?"
"True enough," I replied, and a silence fell between us as we watched what was happening on the screen.
I tried desperately to hide the raging boner in my shorts, but I could tell from her occasional furtive glances that Chrissie knew something was up. After a few minutes of banal dialog between two very hot women, they stripped down and jumped in the shower together, hungrily making love under the cascading water.
"Do most guys fantasize about watching two women together," Chrissie asked, in a manner more analytical than prurient.
"Probably," I replied, trying to be as clinical as she appeared to be. She said nothing in reply, but just gave a half shrug and continued to watch the scene.
The movie got close to the end when Chrissie rose from the couch and stretched.
"I'm going to hit the hay," she said. "Good night, Scott. Thanks for dinner and a movie!"
"You bet," I replied.
I remained on the couch for a discreet moment and then hurried down the hall to my bedroom. I couldn't get my clothes off fast enough and I got myself off in record time. I cleaned up and got back in bed, but my mind was so restless I could hardly sleep.
Fantasies of seeing Chrissie naked, even cavorting with another woman, kept crowding out all other thoughts and I became fixated on my sexy sister to the exclusion of all else. Finally, after what seemed an eternity of tossing and turning, I drifted off to a fitful sleep.
A few hours later I awoke from a startling dream in which Chris had come into my room while I was sleeping and went down on me. It seemed so real, but when I awoke everything in my room was quiet and dark, save for the glow of the street light outside, and the whooshing of the occasional passing car. But my cock was stiff and I had to once again get myself off so I could get back to sleep.
The next morning was Sunday and we bought a Sunday paper and went to a neighborhood café for breakfast. Outwardly everything seemed normal between us, as we passed the paper back and forth, commenting about items we read, and eating our food. Yet I felt anything but normal and I couldn't help wondering if Chris had similar feelings. I was afraid to bring them up. I enjoyed her company very much and I didn't want to do anything to spoil our relationship.
The following Saturday night we repeated our dinner and a movie ritual only this time, after the conclusion of our rented feature, Chris clicked right to the cable channel that showed the dirty movies. Before things got going in the movie, Chris disappeared into her bedroom, returning in a few minutes but no longer wearing her shorts and tank top. She was clad in her short silk robe that cinched around her waist. I couldn't tell if she had anything on underneath, but I was immediately aroused by the sight. Chrissie blithely explained that she just wanted to get more comfortable before settling into watch the second movie.
The film had most of the usual fare for a soft-core porn flick: Male and female, female-female, and threesomes. When one of the latter came on the screen, Chrissie told me that she and her ex-fiancé, Derrick, had invited a woman to join them for sex a couple of times. I was stunned as Chris explained that it had been Derrick's idea, but she thought it was fun to walk on the wild side. I asked her if she had done anything like that before and she smiled.
"Remember the time I went to Florida for spring break with Dee Jenkins and her parents?"
I did indeed. Dee was one of Chrissie's sorority sisters and a very hot number. Chrissie then related the fascinating tale of the afternoon when Dee and her father went to play tennis, leaving Chris and Dee's mother, Gail, back at their condo to lay out in the sun by their private pool.
Gail asked Chris to rub suntan lotion on her back and then reciprocated. They had been laying out for a little while when Chrissie, who was lying on her stomach, felt Gail's hands rubbing more lotion onto her back and legs. Soon Gail was giving my sister a full-out massage and Chrissie was enjoying it!
Emboldened by Chrissie's response, Gail slipped an oily hand between Chrissie's legs and began to massage her pussy through the fabric of her bikini bottom. The combination of the sun, the oil, and Gail's hands were too much and Chrissie rolled over and began making out with her sorority sister's mom!
One thing led to another and within a few minutes, Chris and Mrs. Jenkins were in the shower. From there Mrs. Jenkins took Chris to bed and the two spent the next hour making love. A few days later, Chris went on to tell me, Dee drove across town for a date with her steady boyfriend. Mr. and Mrs. Jenkins took Chris out for a nice dinner, and when they got back to their condo both of them seduced Chris and spent the evening doing her every which way. Chris was twenty years old and it was quite the coming of age, she said.
Of course, after hearing all this I was hard as a rock, and I was barely able to watch the movie while I thought about Chrissie getting naked and nasty with that nice suburban couple. But as the movie wore on I glanced over and saw that Chrissie's robe had fallen open, revealing her white cotton bra and panties. She lazily ran her fingers along the fabric of her bra, watching the action on the screen. I was completely unsure what to do. She seemed to read my mind.
"Why don't you get your robe on so you can be more comfortable, too?" she asked.
I tried to casually walk back to my bedroom and quickly stripped down to boxers and a t-shirt, and then put my cotton bathrobe over them. I returned to the living room and plopped down in my spot.
"There," Chris said, smiling. "Isn't that better?"
Indeed it was since my raging hard-on could now roam free under my robe without being too obvious. We remained that way for a good part of the movie until a very hot scene came on that involved a wife-swapping foursome. I gave a sidelong glance toward Chris who was getting pretty fidgety on the other side of the couch.
"Jesus, this is hot!" Chris exclaimed. "It's making me cream!" I couldn't believe what we were doing, but then things got surreal. "You don't mind if I get myself off, do you Scott?"
"No, I don't mind at all!" I replied.
"You can too, little brother. Don't be shy around me!"
With that I reached inside my robe and fished my cock out of my boxers and rubbed it. I was mostly covered, but Chrissie's robe fell completely open as she massaged one breast through the fabric of her bra and slipped her other hand inside her panties and began rubbing her pussy. The combination of what we were watching and what we were doing was too much and very little time passed before I shot my load inside my robe, letting out a stifled moan.
Chrissie grunted, "Oh, fuck yeah! I'm gonna come!"
I looked over and saw her petite body quaking as her hand moved briskly inside her panties. After her climax, her body jerked in post-orgasmic spasms, her legs seemed to have minds of their own. After lying there for a few minutes, Chris closed her robe and went into the kitchen. She poured herself a glass of wine and brought me a washcloth.
"Here," she said, smiling wickedly. "Better clean up your cream, too!"
We watched the end of the movie quietly and then Chris got up and said good night, giving me a warm kiss on the cheek.
"Oh, so cute," she said, apparently referring to me, and then walked back to her room and climbed into bed. I turned off the TV and lights and went to my own bed.
I lay awake for a good hour thinking about what we had just done. What it came down to was, our inhibitions were breaking down and we now felt comfortable getting off in front of one another while watching a porno. We were crossing lines that most people never dared come near, and the curious thing about it all was my lack of guilt or shame. I should have been loathing myself, but instead I just lay in my bed stroking my cock and thinking about Chrissie, my sexy sister.
The next morning, as usual, we went for the paper and then stopped at the corner café for breakfast. Everything seemed perfectly normal between us, until I worked up the nerve to ask Chrissie about the night before.
"I don't feel guilty about anything," I said softly, trying not to attract any attention from neighboring diners.
Chrissie reached across the table and squeezed my hand.
"I don't either," she said, smiling. "It was really great! I don't know about you, but I'm already looking forward to dinner and a movie next Saturday night. Perhaps we should call it 'dinner, a movie, and dessert!'"
"I agree," I replied archly.
"You know," she went on. "I think it's really kind of neat that we can share this together. I feel like I can say and do things around you that I can't with other people."
"Yeah," I said, "me too."
We finished our breakfast and then went on about our week, our relationship wholly unchanged in many ways, but somehow different, too.
The following Saturday we were once again parked on the couch watching a new soft-core feature on what we had begun to call "The Naked Station." As we started to warm up, Chrissie expressed frustration that my robe was covering up my best parts, so I opened it up, revealing my boxers and my hard cock poking up through the fly.
"That's more like it," Chris exclaimed. "Why don't you just get rid of those shorts, sweetie? They look too constricting."
I immediately dropped my boxers so that my robe was open and I was otherwise completely nude. This was not quite good enough for Chrissie, who had shed her robe and was lying back on the couch in just her bra and panties.
"You can take off that robe, Scott. Don't be shy about showing that body!"
"What about you?" I asked. "Now you're a little overdressed."
"You think I should?"
"Sure, why not?"
"Oh, I was hoping you'd say that!"
Chris removed her hand from inside her panties and jumped up, quickly shedding her underwear and plopping back down on the couch. Now we were thoroughly enjoying the taboo sensation of being naked with one another, even though neither of us had touched the other.
That appeared to represent another line to cross on this incredible journey, and we seemed to understand that moving too fast or skipping over a step might prove devastating to us both. But Chrissie was never shy and she had no problem speaking frankly about what was going on between us. She appeared to have no shame, and in fact possessed a very free and relaxed attitude about sexuality in general and as it applied to the two of us.
Our climaxes were soon upon us, and our hands moved faster and faster as they approached. I began to lose control and was shaking all over when I grunted, "Oh God, I'm coming!"
For reasons she has never been able to articulate, Chrissie reached over at that moment and laid her hand palm up on my stomach and caught the first fruits of my explosion, and the second! Then as she made herself come with her right hand, she took the juices I had deposited in her left and began to rub them onto her glistening tits. At that moment she exploded in a mind-numbing orgasm that caused her to bounce all around her side of the sofa.
When she recovered her senses all she could say was, "That was great, Scott! I don't know what came over me there; I hope you don't mind what I did."
"Hell no!" I exclaimed. "I thought it was hot!"
We lay around naked on the couch for a few minutes, and then we picked up our clothing. Chrissie kissed me on the cheek and smiled, and then we adjourned to our separate bedrooms.
What was also interesting during this time was that for the rest of the week our relationship was platonic. We behaved as siblings/roommates do, and no one would have suspected anything unusual going on between us for those few hours on Saturday nights. That would soon change.
As the next weekend approached Chrissie asked me if we might try something a little different for our dinner and movie night. My imagination ran wild but I said that I was open to whatever she might suggest.
Her idea was that we would get dressed up and head downtown for a nice dinner at a secluded bistro. Then we would return to our apartment for a movie that she would select. That meant rather than watching a movie on "The Naked Station" we would pop in another DVD as a substitute. I could only imagine what my sexy sister had in mind. In the meantime, I would have to be content with lying in bed at night jacking off to visions of her hot body.
On Saturday morning I went to the library, but Chrissie asked me to a game of tennis on campus in the afternoon. After being cooped up among the stacks it was invigorating to get out in the fresh air and run around the courts.
When we got back home we took turns cleaning up for our dinner date (at least I guess that's what we could call it). The sexual tension in the air was nearly electric. Chrissie gave me several knowing looks as we moved around the apartment getting ready.
I was ready a little early and sitting in the living room watching a baseball game when Chrissie emerged from her bedroom looking more beautiful than I had ever seen her. She was wearing a white silk blouse and a black calf-length skirt with a slit up the middle in the back, black stockings, and black high-heeled pumps. Her hair was done up loosely on the top of her head making her look sexy and sophisticated.
Sitting down on the couch next me she concentrated on buttoning one of her blouse sleeves and didn't notice me staring at her fabulous legs. Chris looked over at me and smiled, arching one eyebrow suggestively.
"So, you ready for dinner, sweetie?"
"Sure, let's go. Even if we are a little early we can have a drink in the bar."
Dinner was delightful. Chrissie looked lovely in the candlelight and no one there knew who we were or what our relationship was.
At one point Chrissie raised her wine glass and toasted me with a whisper: "To my dear brother, who takes such good care of me." Our glasses clinked and we drank. "I mean it, Scott," Chris said. "I really appreciate everything you've done for me." Then she looked around to make sure no one was eavesdropping. "And I want you to know that I've been having a great time with you on movie nights."
She reached across the table and squeezed my hand.
"Well," I replied, barely above a whisper. "It has been my pleasure, believe me!"
Chris laughed at the way I said that, with a strong suggestion of double entendre.
"Speaking of pleasure, I think you're really going to like tonight's movie selection."
"Oh?"
"Yes, indeed. I think you're going to be very pleased."
But she said no more on the subject, despite my attempts to weasel it out of her.
We returned home about 8:00 and Chris suggested we get comfortable in our bathrobes and have a couple of glasses of wine. I sat down on the couch while Chris put the DVD in the player; she then sat down in her usual spot at the right end of the couch.
As the movie progressed I was stunned. It was a film entitled "Ties That Bind," about a consensual sexual relationship between adult brother and sister. Chris could not have been more frank with her selection.
It was actually a pretty good movie, in which the characters develop this relationship in slow paces, somewhat as Chris and I had been doing. When the first love scene came on the screen, the chemistry between the characters at the center of the story was unbelievable. It wasn't long before I reached inside my robe to rub my erection, while I noticed out of the corner of my eye that Chris was slipping her hand inside her own robe and diddling herself.
We were in no rush to climax. We went slowly enough so that we could build ourselves up to a crescendo, but when the second love scene came on and the two characters, now freed from their earlier constraints, made love with much greater abandon than they had before it was nearly impossible to hold back. They were really getting it on!
Chrissie's breathing got heavier. Suddenly she scooted over next to me and reached over with her left hand to move my hand away from my cock, and she started to gently stroke my hardness.
I put my arm around her shoulder and reached down to massage her right breast. Her nipples were hard. I doubt more than a few seconds passed before I exploded all over my stomach and Chrissie's hand, and she followed a split second later with quaking explosion of her own.
Either instinctively or through shear presence of mind, she never stopped stroking my cock. We were both shaking from the effects of our orgasms and Chris finally summoned the breath to say, "Oh, yeeeeah!"
Then she rolled partly over and kissed me full on the mouth, snaking her tongue in search of mine and continued that way for several minutes, completely aware of what we were doing and not feeling an ounce of guilt over it. Finally Chrissie fell away, panting and sweaty, just like me. She smiled at me, apparently very pleased with what we had just done.
"Oh, god!" she exclaimed. "That was so wrong, so deliciously wrong! But I can't get enough of you, baby."
"This is so unbelievable," I said, exhaling, feeling spent and floating on a cloud of endorphins.
"I hope you enjoyed it as much as I did."
"Believe me, I did."
Chrissie kissed me some more and then said breathlessly, "Let's go to bed, baby."
How could I resist that offer from such a sexy woman, even if what we were doing was breaking society's greatest taboo? I wanted her, and it seemed she wanted me.
Chris took my hand and led me back to her room where she playfully pushed me down on the bed. She reached into the drawer of her night table and pulled out some matches, lighting the candle on table. The room was bathed with a soft glow, and I admired the curves of Chris's petite body as the candlelight played on her.
I scooted over to give her room to lie down. We embraced passionately, our hands running over each other in abandon. Then she slowly kissed her way down my body, pushing me on my back as she went, finally reaching my midsection and showering my rock hard cock with kisses and licks. After teasing me for a few minutes she took my hardness in her mouth and began to give me the best blowjob of my life. Her head bobbed up down on my member as I floated in space, moaning with delight.
But I didn't want my sexy lover to go unrewarded so I slowly moved her so that she was able to plant that succulent pussy of hers right on my face. Now we were really going at it in the 69 and our moans were muffled by the fact that we hungrily devoured each other. The more turned on we got the harder we worked to turn the other on, and so on, and so on.
After some minutes of this hot oral sex Chris turned around and crawled up on top of me.
"Are you ready?" she asked huskily, but before I could reply she planted a deep soulful kiss on my mouth, swirling her talented tongue around mine. Breaking away she gasped, "Let's make love!"
"Oh yes!" was all I could manage as Chrissie raised her hips and grabbed my cock to position herself right over it.
Then, slowly, she lowered herself down onto my rod. The thrill of entering her was unbelievable. Her pussy felt like warm liquid velvet. The smile on her face showed how much she enjoyed it, and her breathing increased as she dropped down the rest of the way. Now I was deep inside her.
"Oooooh," she moaned. "That feels so good. I never thought it could be so good! Oh, yes! You are such a good boy!"
Her talk turned me on even more, if that was possible. Here we were, breaking through the last barrier of society's greatest taboo. We were lovers and there was no going back. I also discovered just how talented my sexy sister is in bed. She was able to maneuver her hips in such a way that milked my cock for all it was worth. I'd never had a woman fuck me like that and it was all I could do to keep from coming too soon, because I wanted desperately to satisfy her. After several minutes of passionate fucking in this position I rolled Chrissie over and mounted her.
"Woo, baby!" she said, laughing, as I rolled over on top of her. She wrapped her legs around my waist and pulled my face close to hers. "Fuck me!" she gasped, flicking her tongue to mine. I did my best to oblige. "Oh yeah," she moaned, biting her lower lip and running her hands up and down my back.
Her moaning grew louder and more urgent as her body began to quiver.
"Oh my god! I'm coming! Oh Jesus!" She climaxed and then began to urge me on. "Come on baby, come for me. I want to feel your hot come inside me. Give it to me!"
I was delighted that Chris liked to talk dirty during sex, and it turned me on so much that I thrust into her passionately as I released myself deep into her, grunting like some crazed animal. Chrissie loved it, and as I came down from the heights she pulled me down close to her.
"Oh my God!" She gasped as the last bolts of climax coursed through us. "That was so great, baby!"
"Oh yeah," I responded, barely able to speak after what we had done.
"You fuck like a champion, Scotty."
"You're pretty well up there yourself, babe," I responded.
We slowly untangled ourselves and I fell to my back next to Chrissie, who scooted over and draped herself over me. Her hand found its way down to my cock and balls and she cupped them warmly.
"I hope you don't think I'm a terrible person, Scott."
"Why would I think that?" I asked.
"Well, after all, I did seduce you."
"I was more than willing to be seduced by you, Chrissie. I'm very happy we did it. This has been the greatest night of my life. It's a fantasy come true."
"I'm glad you feel that way. I don't feel like we did anything wrong. Maybe I should, but I don't. I've wanted you for a long time and being with you was better than I could ever imagine."
"Then we should both be happy, and enjoy ourselves as much as we can."
"I like the way you think!"
With that we drifted off to sleep in a pleasant haze of afterglow, both of us naked and spent.
At one point in the wee hours I awoke to discover sweet Chrissie bobbing her head up and down on my hard cock. She paused long enough to explain that she woke up horny and thought my cock would make a nice snack. We had another round of lovemaking and then fell back to sleep.
When we awoke the next morning the sun shone through the window blinds, and I could see Chris's naked body lying next to me, the sheet draped carelessly around her. A little while later I was in the kitchen having a glass of apple juice when Chris came in smiling, looking sexy wrapped only in a white bath towel. She gave me a big hug and a wonderful, deep kiss.
"Well," she said after a long pause during which we just gazed at each other and smiled. "Wanna take a shower?"
"Together?"
"Sure, silly. Why not?"
"Yeah, why the hell not?"
I dropped my robe right there on the kitchen floor and she dropped her towel, laughing. Chrissie hugged me again. She looked up into my eyes and we kissed, deeply, like amorous lovers who've just recently discovered the joys of each other's bodies.
My semi-erect cock was rubbing against the gentle curve of her belly, while her tits pressed against my chest. It was a sensational feeling. We headed off for the bathroom and in a few minutes were embracing passionately under the warm spray of the shower. Much to my surprise Chrissie was able to resurrect my cock so I got behind her while she braced herself against the tiled wall. I'd never fucked this much in such a short time, but as Chrissie said later, taboo sex can do wonders for the libido. After 20 minutes of good clean fun, we emerged from the shower and dried one another off.
Chrissie suggested we dress and head out for a good breakfast. We went a little neighborhood café and realized we were both famished from our sexual exertions. Chris positively glowed with pleasure, and I had to admit that I was delighted with the turn that our relationship had taken in the past few weeks. As we ate we shared a few salacious inside jokes, and when the check arrived Chris grabbed it and reached into her pocket for some wadded up bills she'd been carrying.
"Oh no," she said smiling. "I'm getting this."
"Really," I replied, trying to argue with her. "It's no problem for me to pay."
She leaned over and whispered conspiratorially.
"I'm happy to do it, especially since you fuck so great!"
"Well, in that case, I won't argue."
"That's good," she said, leaving a tip on the table, "because I want you to fuck me later."
Chris was so casual about it. I started to realize that she is completely liberated sexually, and has no hang-ups about expressing her wants and needs. We left the café and did a little grocery shopping for the week. Then we spent the remainder of that Sunday afternoon at it like a couple of teenagers.
The following evening Chris was on top of me, sweaty and breathless after she had ridden my cock to a trembling orgasm. My erection was still inside her buttery pussy but was dwindling.
As we lay very still she looked deeply into my eyes and whispered, "There's nothing I won't let you do to me, and nothing I won't do for you!"
Then she kissed me before rolling off of me. We lay spent and drifted off to sleep.
Over the next few weeks we settled into a fairly predictable domestic routine that also included a good amount of sex. A few days after our first weekend together, something happened to make me realize the full gravity of what we were doing.
It was a Thursday evening. I was in my room reading and Chris was in the living room watching TV when her cell phone rang. I heard her say in a pleasant tone, "Oh, hi mom!"
Suddenly I was very nervous. I suppose I knew I would have to eventually acknowledge there was a world beyond us that would be shocked by our relationship, but I wasn't prepared to hear from dear old mom just yet. Chrissie talked to her for a while and then came into my room to give the phone to me. She just smiled as she handed it over and left the room.
I talked with my mom for several minutes. She complimented me on being there for my sister (if only she knew how much I was there for her!), and helping her in her time of need. Mom said it was a real load off her mind to know that Chris was living in a secure and stable environment with someone she could completely trust. Well, I thought, I'm doing all I can to help!
As mom was going on about how proud she was of me, Chris stepped into the doorway of my bedroom with nothing on but a smile. She gyrated her hips and then she turned around to shake her sexy ass in my direction while I was tried to talk to our mother on the phone. Then she came over and lay down on the bed next to me.
It was difficult to stay with the conversation, especially when Chrissie slipped her hand down the front of my gym shorts and started to massage my dick to attention. I continued to talk, but nearly lost it when Chris went down on me. I tried my best to sound normal while talking to mom, but I hardly remember much of what she was saying when Chrissie got me off.
One morning I was at the library drafting a manuscript in my carrel on the third floor. Since it was summer the place was deserted and I reveled in the solitude. Just then my cell vibrated and I could see that Chrissie was calling.
"What are you doing?" she asked casually when I answered.
"Just doing a little work," I replied softly. "What are you up to?"
"I was just sitting around here relaxing and I started to think about you and got really horny. I've got my hand down my shorts and I'm diddling myself stupid. I can't wait for you to get home so you can fuck me."
Well, so much for work. There was no way I was going to be able to concentrate knowing Chrissie was waiting for me at home. I hurried out of the library and back to our apartment. There I found Chris on the couch, her robe open, playing with herself. We didn't even bother to head back to one of our beds, we just did it right there on the couch.
In the two years since we started our relationship, Chris and I no longer live together because, as she said, people would certainly start to get suspicious about an adult brother and sister living together as a permanent arrangement. Chris got her own apartment, which made the logistics of our trysts slightly more complicated, but still well worth it.
We happen to think our relationship is very healthy, despite what society might think, and it's a hell of a lot of fun! Between consenting adults who are well aware of what they are doing, we see no problem with it, depending upon the context of course.
