Camping with the In-Laws PART 2 (MFMF,wife) cooking on the fire. I'd slept better than I thought I would on the air mattress, but I'm sure the naked wrestling match with my wife during the night had something to do with that. Stretching, I rolled over to reach for Natalie again, but she wasn't there. Then I heard her voice and her musical laugh outside the tent. I peered outside the mesh window to see my wife standing by the fire drinking a cup of coffee and chatting with my brother-in-law, Steve. Kellie, his wife, was nowhere to be seen. Nat and Steve talked and teased each other for a while as I observed them. At one point Steve made a sarcastic comment then grabbed my wife and started to tickle her. She squealed and tried to get away, but the big man was too strong and he easily kept her pinned in his grasp. She seemed to enjoy the attention. I felt strange watching another man obviously flirt and tease with my wife -- especially after the comments I had overheard the night before. Steve had blatantly said that he wanted to have sex Nat. Furthermore, his wife -- my wife's sister -- had been teasing me with her voluptuous body most of the evening, then had actually run her hand along the length of cock in my pants just before we retired to our separate tents. I vividly remembered her cries of excitement as she made love to her husband right next to where we slept. There were butterflies in the pit of my stomach as I tried to imagine where all of this might lead. I'd never really thought about being unfaithful to my wife -- or about her being unfaithful to me. But the more I imagined the possibility of bedding and ravishing my sister-in-law, with her incredible, soft curves and wicked smile, the more my libido (and my cock) stirred. On the other hand, I had to admit that the thought of Natalie getting hot and nasty with someone else -- especially this big, rough fireman, who happened to be my brother-in-law -- excited me just as much, if not more. Thinking I must be some kind of a pervert, I pulled my clothes on and went to join the others for breakfast. Natalie blushed a little when she saw me emerge from the tent, but she quickly recovered and moved to give me a hug and a kiss. "You're up early," I said, as I hugged her and nuzzled her soft neck. "Where's Kellie?" "Oh, she likes to sleep in up here," Steve chuckled. "Plus she might be a little tuckered out after all the fireworks last night!" He grinned and winked at my wife. "I dunno. . ." he laughed, "Somthin about this mountain air just gets the 'ol juices boilin!!! From what I heard last night, sounds like you two found that out for yourselves, though. Or maybe that was just the coyotes howling!!!." Natalie blushed bright red again as she looked sheepishly towards me. "Yes, it's awfully quiet up here, isn't it? " she finally whispered. Just then Kellie emerged from her tent. She yawned and stretched as she came toward us. I couldn't help notice her morning camping attire -- a short T-shirt cropped just above her navel under an open flannel shirt, high-cut bikini panties, and a pair of hiking boots. I could clearly see the dark, triangle shadow of her soft bush in the crotch of her panties. I tried not to stare -- especially when Natalie punched me on the shoulder. "Morning!" Kellie yawned and stretched again, causing her large breasts to strain against the shirt, as she moved to where we were standing. Steve offered her a steaming cup of coffee and he threw his big arm around her as she huddled next to him and took a sip. "Everybody sleep all right?" she grinned mischievously as she peered toward us. "Oh yes," Natalie answered, almost giggling. "We were very comfortable in our tent." She seemed to not even notice her sister's revealing outfit. "Yeah....I noticed.....I mean, that's good!" Kellie stifled a laugh as she looked up at Steve knowingly. I decided to change the subject. "So what's the plan for today?" Steve knelt down and began dishing up bacon and eggs from the skillet. "Well, it's pretty much up to you," he said. "There's some good fishing in the lake, or you can go for a hike. Course, you don't have to do anything if ya don't want. Just take it easy and relax. There's a wooden dock just over yonder that's good for layin out and catchin some rays. Whatever ya wanna do." Without a TV or even a telephone, it all sounded pretty boring to me. But Natalie piped right up. "Let's go for a hike, honey! I'd love to take my camera and get some nature shots." My wife has been into photography as a hobby for a while. I indulged her interest financially, but had never actively participated. I felt the same way today. I wasn't really in the mood to go trudging around the forest hunting for butterflies. "I dunno, Nat. I think I'd just like to stay here at camp and maybe read my book. Maybe I can finally finish the stupid thing." It was a lame excuse, but I hoped she'd buy it. She seemed a little disappointed until Steve chimed in, "Hey, I'll show ya around, Nat. I know this place like the back of my hand!" My wife brightened up immediately. "Oh, would you, Steve? That would be so great!" She smiled broadly at him and I thought I felt her shiver next to me. "You wanna come with us, Kellie? Nat looked over at her sister expectantly. "Nah....I think I'll pass, this time," Kellie answered. Then looking directly at me over her coffee cup, she said with a sly smile, "Maybe I'll just hang out here and keep Mikey company. . ." I swallowed hard, thinking of the possibilities of being alone with my sexy little sister-in-law, but everybody else seemed to be happy with the plans as we finished up the meal and cleaned up. Natalie went back to our tent and got dressed for her hike. When she came back out I couldn't help notice what she was wearing. My wife looked pretty dolled up for a walk in the woods. She had on a little sun dress that came to about mid-thigh. The dress framed her luscious curves perfectly, and when she stood with the sunlight behind her, you could see her shape clearly silhouetted. Her hair was done up in a ponytail, and when she walked around gathering some items in a backpack, I noticed something else different -- her breasts swayed and jiggled as she moved around. My wife wasn't wearing a bra! Suddenly, slightly jealous, I stared having second thoughts about Natalie going off into the woods alone with my cocky brother-in-law. When they were ready, Natalie kissed me goodbye and told me to rest and enjoy myself. Kellie was nowhere to be seen, so Steve grabbed a small bag and slung it over his big shoulder. "We'll probably be gone for a couple of hours," he said casually. "There's beer and snacks in the cooler. Help yourself." Then as he strode off with my wife tagging closely behind, he looked back and chuckled, "Don't do anything we wouldn't do!" Natalie looked back at me with a questioning glance, but I just waved as I wondered where her sister had disappeared to. Again I was starting to get mixed feelings about all this, but the obvious stirring in my pants outweighed any reservations I was having. I threw on some cargo shorts, grabbed my paperback from the tent, and a couple of beers from the cooler, and I headed over to the lake to check out the dock Steve had mentioned. The wooden plank boat dock was only about 50-yards away from our camp. It was about 12' by 20' and it rocked back and forth gently with the lazy wake on the water. The sun was shining warmly and I took in the picturesque scenery before I settled down to read my book -- dangling my feet in the cool water. After only a few minutes, I heard a familiar voice behind me. "Mind if I join you?" Somewhat startled, I turned to see Kellie standing there wearing only a sly smile a skimpy black bikini. The scant garment left very little to the imagination -- her fabulous breasts strained to stay inside the tiny triangle pieces of cloth that served as the top, and the thong-style bottom barely covered her pubic mound. "I love to lay out on this dock. Awesome place to get a great tan," she chirped, as she moved over next to me and laid out a large towel. "What do you think of my tan, Mike?" I squinted up at her and drank in the full curves and tantalizing honey-brown flesh so openly on display. "Uh, it looks great." I gulped, and tried to sound casual. "You must lay out quite a bit." I watched her closely as she gracefully stretched out on the towel -- laying on her stomach with her head resting on her folded arms. She glanced over, giving me another dazzling grin and said, "Yeah, I like to work on it whenever I can. But you can't be too careful with all the damage the sun does to your skin and all. I make sure I'm pretty well-oiled before I lay out. I have a hard time reaching my back with the lotion though, would you be a dear and help me put some on?" After everything that had happened so far, I had a pretty good idea I was being set up. . .or at least teased, big time; but I decided to see how far this would go. "No problem, " I said, as I moved over and kneeled by her side. She handed me the lotion as I stared at the magnificent twin globes of her ass, almost completely exposed by the thong. "Where do you want it. . .?" I asked with a slightly strained voice. Then we both kind of chuckled at the possible implications of my question. "Well, how about just my back, for starters," she giggled. I smoothed some lotion onto my palms and started to rub it into her soft skin with a firm, circular motion. "Mmmm.....that feels good," she sighed immediately. "You have strong hands, Mike." I moved lower until the heel of my hand brushed up against the string of her top. She noticed the contact and said, "Mmmff...I hate that stupid string. It always gets in the way and makes ugly lines on my back." Then she reached back and quickly untied it; not only revealing her naked back, but also the sides of her breasts to my view. "That's better. . ." she said, matter-of-factly. "You may continue, sir." Aware of the growing lump in my shorts, I started to stroke her naked flesh again with my hands. I rubbed and kneaded all the way down to the small of her back -- stopping just short of her buttocks. "You're pretty good at this," she murmured. "Keep going, please. I've always wanted my own masseur!" Taking a deep breath, I moved my hands lower. Now I was caressing the soft skin of her heart-shaped ass. Little jolts of electricity jolted through my groin. It was the first time I had touched another woman intimately for many years, and my mind was thinking all kinds of things -- some erotic, some lustful, and some guilty. After a few moments of massaging her, however, lust took over and I began to really enjoy the experience. Kellie was starting to moan softly and rotate her hips in small circles as I continued moving my hands on her cheeks. The lotion had long been rubbed into her skin and now I was just massaging her sweet bottom for the pleasure of it. As I moved lower, my thumbs began to creep into the soft juncture between her slightly spread thighs. One finger brushed lightly against the thin strip of fabric between her legs; it was warm and moist and an electric shock seemed to go through her body when I touched her there.. She arched her hips up and groaned softly. "I'll give you an hour to stop that. . ." she whispered. Finally I decided I better at least pretend to do what I had been asked, so I reluctantly squeezed some more lotion in my palms and began working on the backs of her long, lovely legs. Working my way down to her feet, she continued to coo and sigh while my fingers worked their magic. "There ya go. . .all finished!" I announced at last. "That's what you think, buster," she exclaimed. Then, without warning, she rolled over onto her back. The flimsy top stayed under her on the towel, and suddenly I was staring at her magnificent tits while they jiggled slightly and settled -- her hard, erect nipples stood up proudly. She placed her hands and arms behind her head and smiled at me through half-closed eyes. "Maybe you could help me with my front, too. . .Mike." Almost like I was in a trance, I reached out and began to fondle her beautiful breasts. There was no more pretense of suntan lotion, only a man touching and caressing a sexy, desirable woman. A woman who just happened to be my wife's sister. But that thought and any guilt associated with it was fading rapidly away. Kellie groaned and bit her lower lip as I continued to massage and tease her sensitive flesh. My thumbs grazed her nipples and rubbed the hard nubs in small circles -- teasing them til they were even harder. I shifted closer to her and reached my head down to take one of her rosebuds in my mouth -- sucking and swirling my tongue around the turgid pink skin. She gasped loudly beneath me and one of her hands reached down to grasp me through my pants. Urgently she milked my cock through the cloth as I continued to suck and play with her breasts. She tried to open the button fly of my pants with one hand, but I moved away and snaked my tongue down her smooth stomach, leaving a wet trail to her belly-button. I teased her there with soft jabs and kisses, making her jerk and raise her hips up to meet my mouth. Moving lower still, I reached the elastic of the bikini bottom. Kellie tangled her fingers in my hair and moaned in appreciation as my teeth grasped the fabric and pulled it down, revealing the fine little raven-colored hairs covering her mound. I scooted around until I was kneeling between her legs. Hooking my fingers in the strings at her hips, I pulled the bikini part way down her thighs, then leaned down and inhaled her wonderful musky scent. Her bush was trimmed neatly and I could easily make out the dark line between her lips. My wife's sister panted and moaned as she humped herself up. . .eagerly trying to make contact with my waiting mouth and tongue. Finally I had to taste her. I kissed softly around her inner thighs, then when I thought she would scream in frustration, I swiped my tongue across the entire length of her vagina. She tensed and cried out with a jolt of pure pleasure as I began to lap and swirl at her moist opening. Kellie tasted different than my wife, but very sweet and pleasant. I was surprised at how wet she was already, but I lapped up her juices like it was honey. "Oh, god......that feels so damn good!" she wailed. "Please, don't stop. . .don't ever stop!!!!" I pressed her thighs as far apart as they would go, then I began to spear my tongue inside her, pushing it as deep as possible into her throbbing pussy. She continued to gasp and grunt, as I licked my way up to her swollen clitoris peeking out from its fleshy hood. I began to swirl my tongue around the hard little bud relentlessly. Kellie trembled and shuddered beneath me, clenching her hands and fingers in my hair, and pressing my mouth harder against her sex. "Oh, Mike. . ." she moaned. "Oh, shit. . .I think you're gonna make me come. . ..oh, ahhhhh!!!!!!! I held on for dear life while she bucked and whimpered. When I could feel her body start to spasm, I reached up and tweaked her nipples with my fingers while I continued to lap at her like a thirsty dog. Suddenly she threw her hips way up off the deck and held them there rigid against my mouth. Every sleek muscle in her body tensed and strained as she went over the edge with wave after wave of pleasure. "Yeeesssss........that's it!!!!" she hissed. "Right there!!!! Oh, god.....I'm cummmmiiiiiinnnnnngggggggggg!!!!!!!" She stayed frozen in that position for a moment while she rode out the first intense shock wave of her orgasm. Her eyes were shut tightly and her mouth was wide open as she gave a silent scream of ecstacy. After observing her intense pleasure for a moment, I bent down and continued to kiss and nibble her until she started to come down and relax. She was trembling from head to toe and her hips and buttocks still rocked up and down slightly. Feeling my own need building, I started to pull her bikini bottom the rest of the way off so I could mount her. Before I could disrobe her completely, though, she grabbed my wrists and said, "No, wait!!!!!" Startled, I thought maybe she was having second thoughts. "Did I do something wrong. I thought you liked. . .I mean, I though you wanted to. . ." Now I was confused. She opened her eyes and smiled at me wickedly. "Mike, if you don't fuck me soon, I'm gonna bust. But not here. . .I don't wanna get splinters in my ass! Let's go back to camp!!!" We gathered the clothes and the towel and sprinted back to the tents. Kellie shoved me in her tent and I fell back on the sleeping bags and mattresses while she pulled off her thong. "Let me see that thing," she almost growled. Grabbing the top of my shorts, she ripped the fly open and reached inside to grasp my rock-hard cock. Jacking it furiously with one hand, she urged me to lift my hips so she could pull my shorts and boxers off with the other. When she had me naked from the waste down, she licked her lips and smiled at me. "Yummy!" she said as she bent down and kissed the purple head. Then she opened her pretty mouth wide and engulfed the top half of my shaft in the soft wetness. My sister-in- law swirled her tongue around the sensitive tip a few times, then she began to bob her head up and down on my swollen cock. As she licked and sucked, her hand stroked me gently. I grunted and moaned, humping my hips up to meet her sweet mouth. I saw her reach down and finger herself as she deep throated me -- her nose now grazing my pubic hair, while her hands and fingers caressed and tickled my swelling balls. Not knowing how much more of this sweet torture I could take, I reached out and gently tried to lift her off my tool. I didn't want to come in her mouth. She took the hint and reluctantly pulled off, her lips smacking with satisfaction as she looked up and smiled at me. "You taste good enough to eat!" she giggled. Then she kissed me deep and hard -- our tongues immediately searching and probing each other's mouth with intense passion. She pulled away suddenly, and looking deep into my eyes, placed her hands on my shoulders to brace herself. She swung a leg over and straddled me while I leaned back on my elbow. Reaching down, she grasped my erection and guided it to her steaming opening. Then, with her hands on my shoulders again, she sank down slowly and my cock slid deep inside her. Closing her eyes again, she paused for a moment to enjoy the sensation. My cock felt like it was in an oven -- so warm and wet. I could feel her moisture dripping out and coating us as we sat joined together, her breasts rising and falling against my chest. Finally she started to move; first raising up slightly the grinding her hips back down. Again. . .this time a little farther up the shaft. I could feel her slick inner muscles clinging to my shaft as she rose and fell. Now faster, her breath hot on my neck as she began to pick up the pace. I fought the temptation to push back against her. I wanted to enjoy the feeling of her humping against me for a moment, so I just relaxed and let her have her way. Soon Kellie started to rock up and down with more urgency. Her labored breathing was coming in short pants and gasps. "Uhhh....uhhh....uhhh!" she chanted, each time she sank back down. Her hard nipples scraped and slid against my corse chest hair with each stroke, and her hands started to clench and claw at my shoulders. Unable to stay still any longer, I took hold of Kellie's hips and started to thrust up to meet her. This caused a great moan to escape her throat and she began to move her hips even faster. The slap, slap, slap, of our sweating bodies punctuated our increasing gasps and groans as we hurtled toward mutual release. Soon I felt the familiar stirring of my impending climax. Embracing Kellie tightly, I held her to me; then, with a sudden move, I spun as both around so that she was now laying on her back with me poised over her. Before she could react, I pulled my hips back so that my cock came almost completely out of her. Reaching down, I hooked my arms under her legs and spread her wide, then I slammed back into her and began to piston my swollen tool in and out like a machine. Kellie's eyes glazed over she began to pant and beg -- clawing and writhing beneath me as I furiously tried to push both of us over the edge. "Oh...uhhhnngg......uhhhhh.......uhhh!!!!!!! she wailed. "Fuck me, please fuck me, harder!!!!!" Now I had only one thought -- to plant my seed deep inside this beautiful woman. As I felt the hot liquid start to boil up to the point of spilling out, my hips pounded into her and she raised her ass to meet each of my thrusts as she rotated her hips and ground her pussy against my crotch. A bright light went off in my head and I felt my cock swell up then explode. "Ahhhh......god, here it comes!!!!!!!" I bellowed as I held myself rigid deep inside my wife's sister. It felt like the top of my head was about to come off as my molten lava spurted out into her. Somewhere in the distance I could hear Kellie shouting too and could feel her clawing at my back as she rocketed toward her own climax. Both spent, we collapsed together in a sweaty, happy tangle of arms and legs. Later, as we lay gently holding each other and trying to get our pulse rate back to normal, I began to have serious feelings of guilt again. Facing Kellie, I looked into her eyes and said, "Ya know, this could complicate things. What should we do about your husband and my wife?" Kellie didn't even hesitate. "They should join the party. Why should we have all the fun?" she laughed. "How the hell are we going to talk them into it?" I shot back. "I don't think Natalie will go for this at all. She's your sister, remember. It's just not going to be that easy!!" "Relax, baby. . ." Kellie said as she stroked my hair. "If I know Steve, he's already way ahead of us."
