For almost three years now, I'd had a unfulfilled fantasy. Last summer, that fantasy was fulfilled. Karen and Dave are next-door neighbors, both in their mid twenties. Karen is in good physical shape, even though Karen and Dave have three young children. She has blond hair, large breasts, a flat stomach, fairly wide hips, and a lovely, heart-shaped ass. Believe me, I've enjoyed the fact that my bathroom window gives a view of their back yard, complete with Karen laying out in a skimpy bikini. Dave is built solidly, with lots of muscle. Though I'm only 20, I can't compare to him. However, Dave flies for one of the airlines and is often gone for a week or even more. That is actually what my fantasy centered about. While a three-some would certainly have been enjoyable, I had often thought about Karen and I having an encounter when Dave was gone.

On the day it finally happened, I had the day off. My sister, mom, and dad were all at work. It was hot, about 110, but there was little humidity, as we were in Phoenix. I had gone biking early that morning, returning at 7:00 to see Karen looking good in a knee-length robe. She whistled at me in my biking shorts, the first indication I'd ever gotten that she was flirtatious; uncharacteristically cocky, I flashed her a smile and wiggled my rear at her, yelling out "You want it--come get it!" She laughed and went back inside, her hips swaying from side to side. I wheeled my bike in the garage and stretched down, thinking of her.

Later that day, I was out in the back yard "painting" the fence that hides the pool filtration stuff. Because I was "painting" with a clothes-hostile mixture of linseed oil and turpentine, and because of the heat, I had taken my shirt off, leaving only my old, faded bathing suit on. The other advantage to the bathing suit, of course, was that I could jump in the pool whenever I got too hot (as, shortly, I was going to get).

Anyway, I heard the Karen's door open and shut, followed by the sounds of the chaise lounge scraping on concrete, which soon quieted. I set down my brush and pot of goop and went over and stood on the diving board, which gave me a view over the cinderblock fence. Karen was lying out about ten feet from me, at an angle, facing towards me, her eyes closed. I felt stirrings in my pants as I took in her long, tanned legs, the string bikini covering her pubic region, her flat stomach, her glorious breasts accented by the bikini top, and the cloud of long, blond hair around her face. Rather than have her catch me staring, I called out "Looking good," also unusually bold of me, given how she and my mom talk together.

Karen's eyes popped open and quickly found mine. She looked a little startled, but also a little pleased. She got up and came over to the fence, giving me a _great_ view of her breasts, which were pressing together due to their confinement. I felt my dick harden in response. Then, she mentioned that their pool filter was acting up and that she didn't know how to fix it. "Would you be willing to take a look at it?" was said with a perfectly innocent look. I readily agreed, hard-on or no hard-on.

After I hopped the fence, I followed her over to the filter, adjusting my bathing suit in a completely futile attempt at hiding my interest. As she bent over, it became difficult for me to focus on the filter; the blue bikini bottom slipped a little further into the crack of her cheeks. Gallantly, however, I peered over her shoulder (ok, ok, occasionally I snuck a glance at her impressive cleavage) and paid attention. After moving around her, I looked at the pressure gauge, which was way too high, and cleaned out the trap, which was clogged with bits of leaves and grass. As I kneeled to screw the top back on the trap, my dick, which had wilted enough to move around, slipped down along my leg. Karen, who had bent over (that cleavage again!) to look at what I was doing, didn't seem to notice anything. However, as I tried to shift my member around and it hardened in reply, she seemed to catch on and smiled a bit. When I stood up, my hard-on was quite evident.

Karen just looked at it, smiled a bit wider, and offered me a drink. I noticed that her nipples were a bit more evident through the stretchy fabric of her bikini top. We went inside and I commented on the lack of kids. She smiled again, and said that they were farmed out at friends' houses, so that she could run errands (I wondered if I was an "errand"). She opened a cabinet and reached up to get a glass on a shelf that was just a little bit too high. I reached around her and grabbed a glass and set it on the counter. My cock pressed up against the side of her hip. Then, I grabbed another glass, rubbing my cock further up, around, and back down her hip. By this time, her nipples were fully erect (or so I thought) and, in one place, the faded blue of my suit was spotted dark blue by my oozing pre-cum.

Still playing like nothing was happening, Karen went over to the sink and filled our glasses with water. I stood behind her, reached over her shoulder to get my glass, and pressed my hips against her ass, nestling my dick between her ass cheeks. She pressed her hips backwards and rotated them a bit as she filled her glass.

Still playful, neither of us making a major move, though both clearly wanted to, we went in to the living room and sat down, Karen on the couch, me on another couch facing her. Karen then got up and bent _way_ over to turn on the TV. Her bikini bottom slipped further up her ass cheeks and, from my vantage point, I could see the outline of her swelling pussy lips. She stood back up and started the VCR. She had obviously been watching the porno tape earlier, since it started in the middle of scene. It was actually switching between two scenes, one of a very vocal woman with long black hair and medium-sized breasts being eaten by her husband, the other of a blonde with larger breasts (supposedly their daughter, I guess) listening to the couple and masturbating. When the movie first started up, the blonde was running her hands over her breasts, milking them upwards, tweaking and massaging her erect nipples. The other woman's moans as she was given a tongue-lashing were clearly evident. Then, the scene cut to the couple, as the man sucked on the woman's clit and lightly tongued it back and forth. Then woman's moans got louder and the scene cut back to the blonde.

The blonde still had one hand working on her breasts, but was now also had a hand playing with her belly, pubic hair, and, every once in a while, dipping down to rub along her downy-haired slit. As this was going on, I had been sort of splitting my attention between the TV and Karen. My dick had gotten even harder as Karen spread her legs a bit, allowing me to see a growing wet spot at her crotch. She also was lightly running her fingers along the outline of her bikini top and sometimes over and around her hard nipples. Her nipples, if possible, grew more erect and pushed almost as hard against her bikini top as my cock pushed against my swim trunks. When the black-haired woman orgasmed from her husband's attention, the scene cut to the daughter, who was approaching her orgasm as well, with two fingers pumping in and out of her dripping pussy lips.

I got up, thinking I should have earlier, and sat down next to Karen. I reached my right hand around her shoulder into her blond tresses and ran the other down to trace along the bottom of one breast. I felt her lips vibrate with a muffled moan as I covered them with mine. With my left hand, I traced over to the other breast, spiralled in to the nipple, and gently pulled it between two fingers. One of Karen's hands slipped down to my trunks and began to rub my cock through the short. Our tongues were alternately entwined and probing.

As the blonde in the movie was moaning with her orgasm, I slipped my right hand down from Karen's hair to untie her bikini top. As we broke our first kiss, Karen arched her back, causing her breasts to "present" themselves. As a result, the strings of her bikini top came most of the way around from her back and ended hanging loosely down her sides. When she relaxed and hunched her shoulders a bit, the skimpy blue top fell completely off. She tossed it to the floor and smiled a wicked grin as my eyes popped.

Her breasts, fully revealed and unsupported, were at least a 'C' cup and most likely a 'D' cup. They hung ever so slightly and met naturally at her sternum. Her aureoles were a medium- sized and slightly darker pink than her large, erect nipples. We moved closer and started another passionate kiss. With my left hand, I traced an inward spiral over the smooth skin of her breast, arousing a shiver, and took the nipple between the base of my second and third finger. Then, cupping her breast but also stimulating her nipple directly, I moved my hand in little circles, sometimes pulling the nipple outwards.

During my play with her nipples, Karen had started massaging my dick again. Though it was still restrained by my swim trunks, I felt it jump as Karen squeezed it lightly, and gasped a bit with the feeling. Karen then broke our kiss and moved back slightly. She got up and went over to the TV. I moved over to the TV as well and pressed my hips forward against her ass as she bent over and took the tape out. As she stood up, tape in hand, I thrust my hips even further forward and reached both hands around to cup her breasts and brush her nipples.

Karen twisted around in my arms and nestled her hips against mine. I could feel her breasts, tipped by erect nipples, press against my chest. She kissed me lightly and mentioned that there was a VCR in the bedroom. I was tempted to pick her up by her hips, so that she would lock her legs around me, and carry her into the bedroom. However, appropriate as that seemed, I also knew I probably wasn't quite strong enough. Rather than upset the mood by dropping her halfway there, I tilted my head towards the hallway and followed her into the bedroom.

The room was fairly neat, but some clothes thrown on the chair and the rumpled bed showed that someone actually lived there. (I like a "lived in" look, provided it doesn't cross the line to messy) A decent-sized TV screen sat on the dresser, facing the queen-sized bed. Karen popped the tape in the VCR and started it. The sounds of sex came into being around us. Again, I stood behind her, thrusting my hips forward and massaging her breasts. She bent over a little bit, moving her hips backwards, creating more pressure on my rock-hard dick, and reached around behind her to pull me closer to her. I began running one hand up and down, from breast to navel and back, gradually working lower.

As I did this, I was nibbling on an ear, planting little kisses in her hair, on her neck, on her shoulders, doing my best to drive her crazy.

Karen had been moaning a little and trembling slightly whenever I whispered wetly in her ear or seeded her hair with kisses. After working slowly over the top of her bikini, working slowly down the edges of the bikini, brushing her thighs with my fingers, and returning to massage her breasts, I finally let my hand brush down past her navel, over to top of her bikini, along the edges of the bikini towards her inner thighs, along her upper thighs. Finally, I let one finger extend from that hand, trace lightly along the wet patch on the bikini, and apply pressure, ever so slightly, from the back of her covered cleft to the front.

Karen shuddered and moaned a bit, then stopped me and turned around. Her breasts were red from my attention and her face was getting flushed. Karen kissed me once, quickly, and then tugged my bathing suit down. My six-inch cock (it may have been seven then) sprang free from its long confinement and stood out proudly as I stepped out of my only clothing. As Karen stood up, her breasts brushed along my cock and gained a thin line of pre-cum. She grabbed me by the cock, led me over to the bed, and left me stretched out in the middle of the bed, watching her.

Karen walked over to the dresser and leaned against its edge, next to the TV, which still played, ignored. She spread her legs to show the large wet spot at the crotch of her bikini bottoms. Then, she closed her eyes and began massaging her breasts, tugging on the nipples and pressing the smooth globes together with the sides of her arms. Almost involuntarily, her right hand crept in little circles down to her navel, down to the top of her bikini bottoms, down the blue fabric to run along her slit. She brought fingers to her face, inhaled the scent, and then licked what moisture there was free. The next time her hand crept down, it slipped underneath her bikini. She put one hand on the dresser behind her and raised her hips enough to slide the bottoms free. I was exerting all my willpower to keep in place and not explode right there from the erotic influence Karen was having on me.

I must have made some noise, because Karen seemed to come back to what was going on. She stepped completely out of her bikini and stood nude, glorious, and aroused before me. She then turned around and bent over, giving me a _great_ view of her gorgeous ass and puckered sphincter. Her breasts I saw only as two globes hanging partially in view between her legs. I could also see her pussy, puffy with arousal, surrounded by lightly colored downy pubic hair. Many of the hairs had tiny droplets of Karen's juices hanging from them, a sight that turned me on even more. She licked one finger and then placed it between her legs and touching her sphincter. After lightly rubbing around the rim of her asshole, Karen pressed inwards briefly and then ran her finger forward, bisecting her swollen lips. After licking her finger clean, Karen ran her finger along her swollen slit again, this time pressing a bit deeper, a bit harder.
