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.
