I have a responsible job, nicely tailored suits that I manage to wear comfortably, and otherwise exhibit mainstream appearances. Another side of me, though, is much more atavistic. Over the years I have been extensively involved in numerous outdoor sports, some of them professionally. Even today, I still swim, do light mountaineering, ski, and compete in the occasional triathlon. One of my ex-wife's best friends had been after me to take her hiking for some time. We were friends in our own right, but I owed my friendship with her to my ex. We had partied together numerous times and flirted with each other for the fun of it, but there was nothing between us beyond a casual friendship. A single mother, she had returned to school as an adult, was just finishing an engineering degree and feeling stressed from all of her responsibilities. She wanted to go hiking with me because she knew I was familiar with the mountains, and she thought the exercise and fresh air would put her in the right frame of mind for finals. A good plan, really. Both of us had busy schedules, so it took some time for her to finally pin me down to a date. We agreed to meet early one Saturday morning, drive a couple of hours to a trailhead I knew, and make the 20+ mile hike round trip to a local summit. It was a warm morning in early spring. Jan met me at the rendezvous wearing hiking boots, khaki shorts and a colorful plaid, cotton gauze shirt hanging open over a spaghetti-strap t-shirt. At around 5'9", she was taller than most of the women I knew. Her hair was a light, sandy brown, cut to hang just above her collar, and always seemed to have a wavy, tousled look to it. She had a medium complexion, neither very fair nor especially dark, and piercing blue-green eyes. Her mouth was unremarkable when closed and relaxed, but when she smiled she revealed a set of teeth that seemed large for her and that were offset just a little to the right. It gave her a distinctive, if crooked, and very engaging smile. Her shape was willowy, maybe a little gangly because of her height, with small to medium breasts that pushed straight out in softly rounded conicals from her chest. She never wore a bra (she used to tease that a bra would starve from what she had to put in it) and it w! as evident that her nipples were very circular and prominently convex. Her legs were thin but shapely, her hips narrow without seeming boyish, and her butt was smallish and, to my eye at least, very pleasantly rounded. She was not a model type - mostly because of her teeth and un- augmented breasts, but I had always thought she was damn cute. I was wearing shorts, too. Levi cutoffs that I'd cuffed to be no longer than square-cut swim trunks. On top I sported a well worn, brown corduroy shirt with long sleeves rolled up to just below my elbows. My own build is not overly large. The activities I've engaged in all my life produce compact, well-defined muscles, but not especially large ones. More like a dancer than a stereotypical jock. The physical features on me that tend to receive the most overt appreciation from girlfriends and hopeful gays are my legs and butt. Many women I've known through the years go for big and brawny, which isn't me. To be sure, Jan liked big and brawny, but her taste was more cosmopolitan than exclusive. She had flattered me many times by saying how much she liked my body. Unlike most of my acquaintances, I drove a Honda Accord rather than a four-wheel drive something. I liked its dependability and low profile. And its front wheel drive had proven able to get me just about anywhere I wanted to drive, anyway. In those days I routinely carried my backpack (packed and ready for trekking), a 150' nylon climbing rope, a trauma kit, dry socks and a jacket with me everywhere, usually just tossed into the back seat. Because I knew the way, and because I knew I could get us to the trailhead over the rough dirt road leading to it, I had volunteered to drive that morning. I collected Jan at the appointed place and time and drove off toward the mountains. Along the way we carried on our usual playful banter. She was bright, clever and hugely fond of double entendre. We teased each other with mild, non-stop innuendo as we drove. I confess that I like to flirt, especially with someone I find so attractive. It is enjoyable, not least because it is a little arousing, and passes the time quickly. Only a mile or so before we turned off of the main highway onto the dirt road that wound just over 5 miles to the trail, Jan reached into the back seat and pulled my climbing rope onto her lap. "Now, what do you do with this thing?" she asked, laughing. "Gonna tie me up?" "Hell, Jan, it's not a bad idea but I think you'd have a hard time keeping up if I did." "That so? I always thought it was guys who had trouble keeping up." "Sounds to me like you're dating the wrong guys, or maybe it just happens to them when you take off your clothes." "Ohhhh, I'll get you back for that one. Seriously, though, what do you do with so much rope?" As we bounced along the dirt road toward the trail I explained to her about how ropes are used for climbing and rescue work. She seemed genuinely interested, curious. "I have trouble tying my shoes," she said as we arrived at the spot where the trail departs. "Teach me some knots!" "You're serious?" I asked. "Yeah, just a few. Or don't you really know how to use that thing after all?" What could I say? First I showed her how to tie a clove hitch, then a sheet bend. "If you were going to tie someone up, what knots would you use?" she teased. "Hmmm," I said, "I think I'd start with a French bowline." "French, no less. Sounds appropriate." "Oh, you are so full of it this morning. Actually, I'd use a French bowline because it's so secure, but it doesn't have to be overly tight just the same." "You're making it up - show me." "Ok, give me your wrist. We'll pretend it's a fixed point we want to tie off to." "What's the matter? Afraid to tie them both?" "You're really asking for it, aren't you? Ok, let's pretend I'm really tying you up. Give me both wrists." She held them out as if I was going to handcuff her. I explained as I began that the French bowline is so secure because it takes three round-turns over the object you're tying, then the knot holds everything in place without slipping at all. Unexpectedly, I found tying her wrists to be quite a turn-on. I continued to explain how to tie the knot as I finished, but my heart had begun to beat very rapidly and I was surprised by the thoughts creeping into my head. "Ok," I said, "all finished. Can you get out of it?" I think she had expected to just slip free because the rope didn't feel especially tight. As I had said, though, it is a secure knot. She twisted and pulled, the long free end of the rope lying on the ground in front of her. Determined to free herself, she began struggling more and more urgently. As I watched her I found myself growing quite erect. Here we were, alone in the woods, and her wrists were bound securely together at her own urging. Finally, red in the face and a little out of breath, she held her wrists out toward me. "Ok, I give," she said, "you'll have to untie me." "Do I now?" I said. "What if I don't want to?" "Oh, you're so scary," she scoffed, still full of tease. "What you got in mind, big boy?" "I'm not sure," I said, aware that my grin was just a little menacing, "but you've given me some ideas." I walked toward her one slow step at a time, genuinely unsure of what I was going to do. She looked around and started to back up. "Come on," she said, sounding exasperated, "we need to get going. Just untie me and let's go." I picked up the coil of rope, which had been playing out as she backed away, and continued walking toward her as she retreated. I could tell I was making her nervous, at least a little, which added to my excitement. She was visibly startled when she backed into the side of my Honda. "For some reason I don't want to go hiking anymore, I said." With that I threw the coil over a tree branch projecting out just above and behind the car. "This is starting not to be funny," she said, her voice sharp and bossy. "Just untie me. Now!" I stepped quickly around the car, grabbed the rope, then stepped back to stand in front of her. My hands were sweating and I could feel my pulse pounding in my temples. She lunged forward, as if to ram into me and knock me backwards, but I pulled the rope up tight just as she tried it. All of a sudden her arms were up over her head and she was forced to arch back slightly against the car. Keeping the rope tight so that she couldn't move, I walked around to the other side of the car, threw the coil inside and rolled up the window to hold it in place. When I stepped back in front of her she tried to kick me, but arched back the way she was it just threw her off balance. "My, my," I said, "you've gotten yourself into some trouble, haven't you." I stood just to her side and nuzzled her neck with my nose. "No, I don't think it's time to untie you yet," I whispered, my voice trembling and throaty. "I think I want to play with you instead." "Goddammit," she said, her tone somewhere between angry and frightened. "This really isn't fun anymore - I'm going to scream if you don't let me go. I mean it Dan, cut it out." At this point her breathing was rapid and her face was getting flushed. I didn't answer. Instead, I stood directly in front of her and, using slow, deliberately exaggerated motions, began to unfasten her belt. "Ok, that's enough! I really am going to scream if you don't let me go by the time I count to three. One. two. mmmffff." I was more turned on by what was happening than I had ever been, but I knew I would have a hard time not letting her go if she really started to scream. When she counted "two" I stuffed one of my spare, dry socks into her mouth. I reached into my trauma kit and retrieved a 2" ace bandage, which I wrapped around her head to keep her from spitting the sock out. Once I had the ace bandage fastened I returned and, without saying a word, finished undoing her belt. Then I unbuttoned the top button of her khakis. I looked at her face. Her eyes were wide, frightened, watching me, and her breathing was audibly labored. I looked straight into her eyes and began slowly lowering her zipper. She continued to protest with muffled cries into the gag. I couldn't make out what she was saying. When I had unzipped her shorts, I drew her T-shirt out of them and up, exposing her belly and breasts. Her stomach heaved deeply with each of her breaths. Her skin was flushed and becoming damp with perspiration. I pushed myself to stand between her legs and began kissing her nipples, each in turn. She yelled something else into the gag and renewed her struggling in earnest. At the same time, a tear welled up in her eye and escaped down her cheek. Like I said, it was a secure knot. After teasing her nipples for several minutes, I began trailing kisses down her belly, enjoying the undulations of her breathing and efforts to pull away from me. When I started to pull her shorts down she tried to clamp her legs together, but I was already standing between them. Still, she was strong enough to make it difficult. I stopped trying to remove her shorts and, instead, slid my hand down her belly and beneath the waistband of her panties, stopping just as my fingers settled into the pubic hair covering her mons. After waiting a few seconds, I began to push down again. I watched as she shut her eyes tightly - tears now running freely down her face. The pounding in my ears was deafening and I knew I was not going to stop. When my fingers reached the slit between her legs I had to catch my breath. She was wet. Not wet, she was soaking. As I began to slide my finger up and down through her heavy, slippery fluids, I found her clit as firm and erect as my penis felt to me. It was a thrilling but very strange mix of sensations. On the one hand, her body was more aroused than any woman's I had ever touched, but the tears continued to stream down her face. I forced her panties and shorts down together, pulling them off over her hiking boots one foot at a time. My god she was a sight, arched back against the car, arms stretched out overhead, naked from just above her breasts to the tops of her socks. She was a true beauty and I found something fantastically exciting about her exquisite vulnerability. I lowered my own shorts and stepped out of them, my erection as hard as a post. I stepped back between her legs and pushed her harder against the car for support, then reached down and pulled her off her feet, cradling the crooks of her knees in the crooks of my elbows. "I'm going to fuck you now, Jan," I whispered hoarsely. I rolled my hips forward and up, watching my penis enter her as I did. It was the most erotic thing I have ever seen. She continued to cry, but was grinding back against my thrusts. Hard. With each penetration our pubic bones crashed together, her pussy eagerly receiving me in spite of her tears. I fucked her like that for a delicious eternity. After quite some time I spoke, breathless. "Don't fight it, babe. Let it go. I want you to come while I'm fucking you." All at once, just after I said it, she did come. She actually ejaculated - I had never seen anything like it before. As I heard her grunting into her gag she exploded with a burst of fluid that splashed off of my crotch and soaked me past my knees. I thought I would pass out from the sensation it gave me. It was magnificent! After a few minutes I went to the other side of the car and released the rope. She slid down to the ground, sitting on her khakis. I removed her gag and untied her wrists. When she finally stirred, she dressed without saying anything. We got in the car and drove back toward the city in silence. The gravity of what I had done began to overtake me. Clearly, she seemed to have been taken against her will, but just as clearly she had enjoyed something about it. I did not know what to expect. When we got to where she had left her car she got out and unlocked it. Before getting in, though, she walked over to my window and leaned down on the sill. "I didn't know I could come like that" is all she said. Then she got into her car and drove away.
