It all started when my wife Linda had to leave on an unexpected business trip. We had already made plans to visit her older sister Carol on the same weekend, but the trip was unavoidable, and Linda's boss couldn't be persuaded to reschedule. So she had to break the news to Carol that we wouldn't be available for a day of bicycling in Reservoir State Park.

Linda and her sister have always been very close. Although they only live 30 minutes away, they often indulge in lengthy phone conversations several times a week. They enjoy each other's company so much, that it sometimes infringes on our own relationship. Whenever I brought this to her attention, I was sternly reminded that Carol was living on her own, and was shy about dating. Linda said it was her duty as a sister to include Carol in our social plans whenever practical, or until she is able to find a steady boyfriend.

So for almost an entire year, we invited Carol to almost every activity: movies, shopping excursions, music concerts, and sporting events. We had hoped that getting her out of the house would also introduce her to new people, increasing the odds of her meeting that special someone.

Up until now our efforts had resulted in string awkward dates and a handful of phone calls from various guys, but nothing close to an actual love connection.

We were genuinely puzzled at Carol's lack of success in attracting men. It's not as if she is physically unattractive. . .

Carol is in her late 30's, but she could easily pass for 29, if not younger. Her facial features are pleasing, and she looks quite fetching when her hair is done-up and her lips are glossed. Her complexion is dotted with light brown freckles, which nicely compliment her tanned skin, auburn hair, and hazel eyes.

She is a few pounds over her "ideal weight", but I wouldn't describe her as chubby. Curvy would be a more fitting term, as she tends to carry her excess pounds in the hips and thighs. Her breasts are just a B-cup, but they are perky and well proportioned.

As for her interests, Carol prefers to be outdoors, and thrives on gardening, hiking, and camping. She is something of a "tom-boy", while retaining a soft-feminine side. She has a whimsical personality, which can be simultaneously aggravating and charming.

Linda called her sister about the unexpected business trip, and apologized for canceling our plans. She felt guilty about disappointing Carol, and did not want her be lonesome all weekend. Linda's solution was that we simply go bicycling without her, and to my surprise Carol agreed. . .

I wasn't entirely opposed to the idea of spending the day alone with Carol. After all, she is usually good company, and she shares my enthusiasm for cycling. Without Linda in-tow, we could ride at a much faster pace. I thought that we could even reach the reservoir and return home in time for supper.

So the plans were set. I take drop-off Linda at the airport on Friday morning and she would return the following Monday. Carol and I had arranged to meet at the trail's entrance on Saturday morning at nine.

I arrived at the park at little early, unloaded my bike from the roof rack, and performed a quick safety check. I knew from past experience that having your bike fail during a lengthy ride could result in a long walk back to the car, or a painful injury, or worse. I was busy adjusting the brakes, when I heard Carol's Honda pull-in beside me.

The first thing I noticed was her outfit... She usually wears loose, comfortable clothing. Her choice of apparel is never unflattering, but definitely not revealing. Carol surprised me by wearing a pair of snug, thin, cycling pants. They were bright yellow, with blue stripes along sewn along the sides. The tightness of the shorts accentuated the sexy curves of her hips and outlined her sumptuous bottom. She wore a blue tank top with a matching sports-bra underneath, which complimented the stripe of her shorts.

My eyes traced a path down her deeply tanned legs, stopping briefly to admire her well-toned calves. New running shoes and crew socks completed her ensemble. Along with her sexy outfit was whole new attitude. She exuded an unusual air of confidence. You could tell that she felt good about herself.

I knew it was wrong, but I just couldn't get over how gorgeous her butt looked in those cycling shorts. I never really noticed her ass, because she always wore baggy jeans and khakis. The sport's bra made her breasts seem larger, as elastic fabric pressed her cleavage above the neckline of her tank-top.

I've spent a lot time with Carol of the past few months, but I never once thought of her as sexy. Because she is my sister-in-law, I've always thought of her as a family friend, and never as a potential bedmate. I was beginning to have second thoughts about our day together.

I caught myself becoming a victim of my own masculine-ego and active imagination. Who was I kidding anyway? We were just two adults enjoying some physical activity, and each other's company, and that's how we were going to behave...

We started heading down the trail, riding side-by-side at genital pace. The air was damp and refreshing, filled with the woodland scents of aromatic cedar and earthy moss. Since it was still morning, the path was quiet enough to maintain a steady conversation.

As we shared our mutual appreciation for the beauty of the forest, Carol recounted the trip she had taken to the California Red Woods, which was part of "conservation studies" program at college. She was well versed on the topic of ecology, and wrote a series papers concerning the reservoir's impact on our local ecosystem during her graduate studies.

Steering clear of serious topics, I pointed out the many new improvements to the park's trail system. The sexual tension I had sensed before had all but completely vanished...

Later that day the trail had attracted more riders. This made it necessary for us to travel single file. Fearing I would set too fast of a pace, I let Carol take the lead. Watching her ass perched upon the tiny bicycle seat rekindled my desire.

When we reached a steep incline, she lifted her butt slightly to gain more power. I gazed at the back of her thighs as they slowly pumped the pedals. They were thick, firm, and close-shaven. As we approached the summit my attention was momentarily fixed on her lovely her calves and the pleasing contour of her ankles...

The early afternoon sun converted the dampness into a fog of humidity. A dark patch of sweat gathered between Carol's shoulder blades, and outlined the seams of her bra. I noticed a wet area developing at the small of her back. The trail was flat and un-shaded for the next three miles, during which time I was mesmerized by the continuous rotation of her hips.

We stopped at a sign-post, displaying a map of the park, and sipped bottled water while tracing our progress. We had ridden 20 miles, and had 15 more to go before reaching south end of the reservoir.

It was almost noon, and I asked Carol if she wanted to complete the entire trip. Carol was never one to back down from a challenge. She wanted to ride the whole route, which was possible at this point, but we wouldn't arrive back until after 5pm. With our course decided, we pressed onward...

Even though we were short on time, Carol couldn't resist investigating one of the new trail branches. The fresh asphalt was fast and smooth with a downward grade. We were soon rewarded with a panoramic view of lake. Across the wide expanse we could see dozens of bathers congregating at the public beach. Sailboats dotted the water's surface, their colorful sheets reflected in the rippling waves. We paused to admire the serene beauty of a summer afternoon.

Our silent reverie was suddenly interrupted by a sharp hissing sound. Carol had punctured her front tire on a sharp piece of quartz, which littered the trail's shoulder. We carefully moved our bikes to a shaded area to assess the damage.

I unpacked a replacement inner-tube and a wrench from my repair kit. Carol was watching me intently, sitting cross-legged in the grass, ready to offer her assistance. Her knee lightly pressed against my thigh as I loosened the axle bolt and freed the wheel from the bike's frame. Our hands touched as Carol kneeled beside me to steady the wheel while I removed the tire from the rim.

I was sweating heavily from the exertion of wrestling with the inner-tube. After finishing the repair, I took a few generous swallows of water, and laid back in cool grass to rest. Carol squatted next to bike and attached the mini-pump to the valve. Her suggestive posture afforded me a perfect view of her lovely backside.

She began the tedious task of inflating the new tire. As she worked the mini-pump's handle back and forth, her legs and buttocks alternately flexed. The sight of her was so overtly sexual that I could not stop myself from staring. Droplets of perspiration formed on her forehead and trickled down her neck, collecting in a large wet patch covering the entire front of her shirt. Even through her the thickness of her sports-bra her nipples were now plainly visible.

Carol's unconscious display had finally overwhelmed my self-control, and I found myself getting extremely hard. I realized, much to my distress, that a bulging erection would be difficult to disguise through the elastic material my bike-shorts. I didn't want Carol to think her brother-in-law was some kind of pervert, so I decided to distract myself by meticulously re-packing the repair kit.

Carol propped her bike up against a fence post to test the air pressure. She knelt down to read the gauge and then suddenly lost her balance. She tumbled backwards, careening down the slope, and without any warning landed perfectly in my lap and on top of my aching hard-on.

I couldn't have imaged a more embarrassing predicament. Her warm bottom was pressed against my throbbing cock. She clung to my shoulders with her arms tightly wrapped around my neck, our embrace preventing her from rolling any further down the embankment. My chin was firmly nestled in the cleft her cleavage.

We both sat there frozen in position, completely stunned and unable to think of anything polite to say. We were equally embarrassed and aroused by our unlikely predicament. Our eyes connected for a brief moment before quickly turning away.

Not knowing what else to do, we both started laughing. I rolled out from under her, and standing-up slowly, brushed the leaves & grass from my chest. Then I offered my hand and helped Carol to her feet.

"I'm so sorry!" Carol exclaimed, "I didn't mean to fall on top of you. I just started rolling backwards and everything happened so quickly that I just couldn't stop myself. I hope you're not seriously hurt."

She stopped to consider something and then she added blushingly, "I think I may have injured a sensitive area... if you know what I mean."

Carol glanced conspicuously at my crotch, and I'm certain the she had been aware of my erection; I don't think she could have mistaken it for anything else.

I nervously laughed, doing my best to make light of the incident. "I'm not the slightest bit damaged. I was just more surprised than anything else. Do you think you can still ride your bike?"

Carol smiled slyly, "Yes, thanks to my relatively soft landing." she winked knowingly. "I'm ready to start again whenever you are..."

With that episode behind us, we proceeded explore the new trail branch. Three miles later we were faced with a dead-end and a signpost advising of future projects and expected completion dates. Beyond the sign-post was a dirt path leading to a sheltered table and water-pump .The rest area isolated from the trail by a lush overgrowth. The location provided us with another terrific view of the lake. We filled our water bottles and sat together on the tabletop. Our legs touched as we scanned the horizon.

Since we've known each other Carol and I have spoken on many occasions. We've talked casually on the phone, chatted for hours at family gatherings; however, we've never engaged in meaningful conversation. In many ways so she was as unfamiliar with me as I was with her. So when I asked her how she enjoyed having so much time to herself, I assumed that she would offer cheery reply, but I never expect her to confide in me.

"You would think being alone would have many advantages." Carol began. "Like doing whatever you want, whenever the mood strikes you, without making compromises. You can shop when you please, watch TV until the wee hours of the morning, have supper in your bedroom... but sometimes it's a miserable lonely existence." Carol's voice began to tremble and her eyes were moist.

"I'm sorry Carol. I didn't mean to bring up a sensitive subject. I know you've been struggling with this for awhile, and I thought that you had really grown accustomed to the single-life." I gently rubbed her shoulders, held her close, and softly patted her back.

"Please, don't be sorry, you didn't do anything wrong," she laughed. "I'm the one who should be apologizing for sobbing like a spoiled child. After all, I have a lot to be thankful for. It would just be nice to have someone who could take me out to a nice restaurant once in a while."

"Yes, but there many things our best experienced on your own." I pondered out loud, trying my best to sound encouraging

Then, out of nowhere Carol started grinning. "Like satisfying ones sexual urges, for example," she said with a hint of mischief. "I think I've been alone for so long that I've become a certified expert in the field."

I didn't know how to respond, so I just pretended not to have heard her admission. Carol must have sensed that I was becoming uncomfortable with this new level of intimacy. She playfully elbowed me in the ribs and we both started laughing uncontrollably.

"You never know. Things might look-up a whole lot sooner than you'd predict," I said. "I've noticed that you've changed for the better over the past few months. You've lost weight, gained muscle-tone, and you've developed a great deal of confidence in the bargain. It seems that you have a renewed sense of yourself."

Carol laughed, "You really know how to flatter a woman. My sister is so lucky to have you."

I could tell she was basking in the glow of my awkward praise. She thanked me for being a good listener and gave me one of those proper, social hugs, then playfully swatted my butt as she walked away...

With long ride ahead of us, we set out at a faster pace and took fewer breaks along the way. Before we knew it the sun was setting and it was getting fairly dark. Apparently we had been too ambitious and traveled a lot further than we thought. It was almost 6pm and we were still seven miles away from the park entrance.

Ravenous from skipping both lunch and dinner, we stopped to munch an energy-bar and flip-on our headlamps. Carol bent over and touched her fingertips to pavement to stretch her hamstrings. Suddenly, I imagined her naked; the folds of her pink vulva nestled within the crease of her behind. I regained my composure, and quickly put the image out of my mind.

Being in the woods at this late hour made Carol very anxious, and I could tell she was beginning to worry about our safety. According to my odometer there were only 4 miles remaining. I decided to lead for the rest of the way.

With only a few minutes of daylight remaining, we drastically quickened our pace. We arrived at the entrance shortly after sunset, our lungs burning and our pulses racing from the combined intensity of anxiety and physical exhaustion.

I opened my truck and pulled some sports drinks from the cooler. We sat together on a park bench and caught our breath, laughing at our foolishness. We felt strangely connected by our unsettling experience in the woods, and before I knew it we were unconsciously holding hands.

"You know there are a lot people visit the park after hours to engage in illicit activities," she said coyly. "I was wondering how we were going to explain ourselves to rangers".

"Oh, I'm sure we could have come-up with something. Not that anyone would've believed us," I added.

Carol was quiet for a moment; her fingers tentatively stroked the back of my hand. "I want to thank you for getting us back safely," she said, and then she planted a wet kiss near the corner of my mouth. I fought the urge to return her kiss. I gently squeezed her shoulder and smiled. Carol smiled back, her face blushing brightly, she leaned in closer and she kissed me again, this time squarely on the mouth.

It was at that moment my resistance crumbled. I returned her kiss with unbridled passion. Soon we were necking like a pair of teenagers, panting for breath. We pressed our lips together, our tongues exploring each other's mouths. In between kisses I nibbled her ear and caressed her arm. My fingers stroked her hair and traced the delicate crease of her lower back.

We broke free for a moment. Carol kissed my neck as she dropped her bottle to the ground. She repositioned herself and straddled my waist, pressing my erection into her crotch. My hands caressed both halves her rounded bottom. We when we kissed again my hands moved to her heaving breasts. Carol's boobs were smaller than her sisters, though her nipples were larger and grew harder when erect.

We must have carried on for at least 20 minutes before one of us realized that we were mashing and groping each other on a park bench, only yards away from the main entrance. "Maybe we should find somewhere more private", Carol suggested.

I walked back to car and retrieved a old emergency blanket from trunk, then together we ventured 50 yards down a wooded slope, settling a location away from the path and well hidden from the main entrance.

I hastily built a crude mattress of dried moss and leaves and arranged the blanket over the pile. I turned to see that Carol removed her shorts and panties, hanging them on nearby limbs. I could just barely see her trimmed bush in the failing twilight. See turned away and stripped off her sports bra. Without hesitation I scrambled out of my shoes and shorts, tossing them behind me. The notion of having forbidden sex with my sister-in-law made me so incredibly hard that me dick hurt with pure lust.

Now completely naked, we embraced with renewed fervor. My hands wandered Carol's body freely, exploring the moist folds her vulva and the crack of her ass, brushing against her warm pubic mound.

Carol moaned with pleasure and grabbed hold of my solid cock. Wetting her palm with a mouthful of saliva, she expertly fondled my aching member with one hand, while gripping my balls with the other. Her fingers glided along the length of my shaft, squeezing my head at the end of each stroke. I would've never guessed that Carol would know so much about pleasuring a man. Who would have known that under her plain exterior lurked a full-blown sex fiend.

She must have realized that I was about to cum, because let go of cock and motioned me down on the blanket. Once on her back there she raised hips she opened her legs, giving me full access to her swollen pussy. My fingers traced the delicate ridge of Carol's pelvis and caressed the inside of her milky white thighs, passing gently over hips and back again. When she could no longer stand it, she placed my hand on her vagina and pushed my fingers into her wetness.

I spread her labia wide, plunging my middle-finger into her slickness, and rubbing her clit with my thumb. Sensing her mounting pleasure, I introduced another finger into her slippery hole, opening her even further. My fingers slowly eased in and out of her vagina as I planted kisses on her soft stomach, my nostrils were filled with her scent of her arousal.

As I finger-fucked her cunt, our pace gradually quickened until Carol released a moan so loud that I thought we would be discovered. I kissed her forcefully with my tongue to silence her screams. Her orgasm built to a fever pitch. Her hips writhed and bucked, and the walls her love-hole tightened and spasmed around my fingers.

When her thrashing subsided, she pushed my faced between her thighs; I began to drink her sweet cum. I lapped her inner-lips the flat of my tongue and poked my nose between her labia. Using long deliberate strokes, I licked my sister-in-law's tender slit under she was ready to orgasm again.

This time I was going to make sure that her mouth was busy. Without losing contact with her cunt, I grabbed her hips and flipped her over. Then I guided her head towards my throbbing cock. Carol took the hint, and soon we were in a text-book 69 position with her on top.

After a few clumsy moments Carol was sucking my cock like a pro. Her lips were wrapped tightly around my shaft, and her tongue flicked the sensitive area underneath my cock-head. In minutes I was about to explode. I started groaning loudly, hinting that I was nearing orgasm, I did not wanting to cum just yet. I tried to pull away, but she held keep me in her mouth and swallowed my entire load...

We remained embraced the 69 position. I continued to lick her moist snatch while she toyed with my deflated penis. Following 10 minutes of gentle coaxing, my cock came back to life.

I rolled Carol over on her stomach, kneaded her back and squeezed her ripe bottom. I placed my knees between her thighs and spread her legs, then pulled her hips upward. I slid my hand over Carol's slick vulva and teased her clit; her swollen labia protruding between my fingers. Carol moaned and firmly pressed her ass against my pelvis.

She said "I've never fucked doggy-style before... It's been years since I've had sex with anyone. "

"Don't worry. We'll take slow and easy." I assured her. "Just let me know if it hurts and I'll ease-up until the pain passes."

With that I placed the head of my cock into her dripping pussy, and gently pushed forward. Carol instantly with yelped with surprise. "You're much bigger than I realized" she exclaimed. I remained perfectly still inside her for several moments, as she began to grow accustomed to the sensation.

Pushing forward using short strokes, I could feel her vagina becoming less tense. My tentative prodding soon progressed into full, eager plunges. I allowed my entire shaft to penetrate her deeply. Carol bucked and groaned as her buttocks slapped loudly against my thighs.

I tried to keep from cumming, but the sight her full ass spread before me in the moonlight, with my cock pumping in and out of her moist hole, was almost more than I could bear. I could tell Carol was about to orgasm by the intensified pitch or her moaning. We both came at once just moments later and collapsed together in a post-coital kiss...

We strapped the bikes to the carriers and I followed Carol back to her house where we enjoyed each other again before falling asleep in her bedroom...

Carol continues to look for a steady boyfriend, we meet for bike-rides every other Saturday morning, and my wife is happy that I have found someone to share my hobby with.
