I hated going on vacation with my parents, after all I was almost sixteen now and had looked forward to spending some time on the beach with my friends this summer. Joey, Mike and I had already planned how we were going to seduce Betty Jo and Mary and I hated to go off and leave all the fun to them. But as the day of our departure got closer and my pleading fell on deaf ears I resigned myself to three weeks of anguished boredom.

Camping!!!! My God!! In the mountains, Aarrrrrrgggggg! Shit there wouldn't even be a Seven-Eleven or any kind of store for miles. How was a teenager supposed to survive. I ducked my head and sullenly helped pack the pickup and trailer for the trek to the mountains.

At least we had a trailer, we wouldn't have to sleep on the ground or poop in the bushes. Our trailer was a well equipped, self-contained twenty-four foot rolling home. It had a large table in the front that folded up and the seats scooted together to turn the whole front of the trailer into a humongous bed, then there was a small half height divider then the dining area and kitchen with the bathroom right at the back. It had a refrigerator and heater that used both electricity and propane and Dad got a generator to take along so we could have electric power. After all, like he said, the girls couldn't be without their curling irons.

The girls in this case were my mom and my fourteen year old sister, who aside from being a royal pain in the ass sometimes, could be a lot of fun to be around. My mom was in her early thirties and was a real knock out, at least that's what all my friends keep telling me, and my sister was developing curves in all the right places, in fact she was just a junior version of mom.

"Billy", my dad yelled, "get your ass out here and quit day dreaming. We need to get loaded up so we can leave as soon as Jill gets home." Jill was my sister and had a cheer leader tryout for next school year that she just had to be to. Yeah, just so she could get out of helping load the trailer. She was cute though and sexy enough to be a good cheerleader.

"Okay Dad", I yelled back, "be just a minute. I'm just picking up some magazines to read on the way." I had taken the covers off a couple of Sports Illustrated and was carefully reattaching them to a couple of my fuck magazines, that way, if I was careful, I could look at them and nobody would know the difference. I slipped them into my travel bag and picking up the rest of my stuff, carried it to the trailer, and helped Dad finish loading up everything. Just as we finished Jill got home.

"Good timing, Sis", I growled.

"Yeah, just like I planned it", she grinned back at me.

"Get your stuff loaded Jill", Dad ordered, "we're just about ready to take off." Turning toward the house he yelled, "Jeannie, get your buns moving, this caravan is about ready to depart."

"Billy, please come help me carry my stuff out, pleeaaaase", Jill asked, smiling softly at me and batting her big blue eyes. I melted. I couldn't stay mad at her. All she has to do is give me that soulful look and I'd do anything for her. And I do mean anything. A few minutes later we came staggering out of the house loaded down with three suitcases and an overnight bag.

"Holy shit", Dad grumbled, "I thought we were getting away from it all, not taking it all with us". He helped us load it in the back of the pickup, arranging it so we would have plenty of room to sit and move around. Our pickup had a shell on it and a carpet kit in the back, so while you couldn't stand up, it was still fairly comfortable.

Just then Mom came out of the house with an armful of last minute items she'd picked up. We took them from her and stowed them away, then Dad turned back towards her.

"That everything", he asked.

"Think so", Mom answered, "if it isn't we'll just have to pick up what we need along the way."

I was standing staring at Mom like I'd never seen her before.

Man, I suddenly realized why the guys all thought she was so hot.

She was standing talking to Dad, one hand on her hip and one leg bent slightly at the knee. She was wearing a pair of tight white shorts, and I do mean tight, that hugged the soft curve of her ass with the seam pulled tightly into the lovely crevice separating her cheeks, and a soft white knit blouse that was cut waaaay low at the neck showing a vast amount of cleavage and the tops of her breasts. She wasn't wearing a bra and her nipples made large indentations in the soft material. The tan that she'd been working on all spring accented the whiteness of her clothing and her long blonde hair fell softly over her shoulders

My Mom was a Babe!!! Big Time!!!

"Well, let's get going then",

"Just a minute, Dad", Jill said, "I gotta get out of this cheerleader outfit."

"Okay hun, but hurry", he replied as she scurried off to the house to change. In a few minutes she returned, wearing a pair of shorts that were as tight as mom's and a cut of t-shirt that just barley covered her boobs. She wasn't wearing a bra either cause I could see the indentations her nipples made in the soft cotton fabric.

"All aboard", Dad yelled, holding up the shells rear door.

Jill crawled in first with me right behind her. As she crawled toward the front of he pickup her ass waved invitingly in front of me and her t-shirt fell away from her body, exposing two succulent globes swaying as she moved toward the front. My prick twitched uncontrollably. As we moved pillows and cushions around till we were comfortable, Dad closed the tailgate and shell door and got in the cab.

Dad started the truck and we were off on our adventure. As we pulled out onto the street Dad looked over at Mom, she was leaning against the door, smiling softly at him.

"Well here we go", he said, "sure as hell hope your idea works!"

"Oh, it will", she said giggling as she slid closer to him, "they're too much like us for it not to."

Jill and I had made ourselves comfortable in the back, her in one corner and me in the other. After we had been traveling an hour or so Jill looked over at me and said, "Well big brother, don't go getting any wild ideas, but I gotta unsnap these shorts. They're cutting me in two." Then she unbuttoned the top button and slid the zipper down an inch or two. "Ohh", she sighed, "that feels sooo much better."

I glanced over at her and giggled, "You've really got some pinch marks, sis." Then I quit giggling, besides the angry red marks the too tight shorts had made I could see a little light blonde hair peeking out at the opened zipper. My cock twitched involuntarily as my eyes swept over her soft belly to the hair just barely visible. She didn't have any panties on. I hadn't thought so, couldn't see any panty lines under those white shorts. Mom either for that matter.

"Let me borrow one of your magazines", Jill asked.

"You don't like sports magazines", I retorted, "I've never seen you even look at one before."

"I know", she replied, grinning, "it's just something to kill some time. Besides they have some pictures of good looking hunks in them".

"Get your own damn books", I answered, irritably, putting the magazine behind me, "I'm going to get some sleep." With that I rolled onto my side and feigned sleep. She didn't do much for a few minutes, then as she twisted and turned, trying to look out the side window, her zipper slipped a little lower, exposing even more pussy hair. My cock twitched uncontrollably, starting to make a tent in the sweats I was wearing. Nothing happened for a few more minutes, then after looking at me for a minute to make sure I was asleep, she crept down to my duffle bag and retrieved my other magazine. Damn, I'd forgotten about it. She situated herself again, got comfortable and flipped open the book. I heard her suck her breath in, in a surprised gasp as she glanced down at the picture. I knew what she was looking at, I had those books memorized. She glanced over at me again, to make sure I was asleep, then slowly flipped the page. Her tongue crept out to wet her suddenly dry lips and I saw her breasts heave with the sudden intake of air as she tried to catch her breath. She slipped her hand up under her t-shirt and slowly began tweaking her breast, rolling her nipple between thumb and forefinger, then grasping it and pulling it away from her body. As she slowly flipped through the pages of the magazine, her breath became more labored and her hand moved from her breast, across her stomach and into her shorts. The zipper crept lower, making it easier to slip her fingers through the soft blonde curls and into the waiting slit. She bit her lip to keep from crying out as her fingers worked over her rapidly moistening cunt. Every once in a while she'd pull her hand from her shorts and flip a page, then right back to stroking her pussy again.

By this time my cock was throbbing wildly and tenting my sweats out in front of me. I stretched and pretended to be waking up.

"What are you doing with my magazine?", I demanded, feigning anger, as I rolled over and grabbed for it, "I told you not to look at them."

"And I can see why", she retorted, holding the magazine away from me and trying to push me away with her other hand, the one that had been in her pants. I quickly grasped it and pulled her toward me. I brought her hand to my face, directly under my nose.

"Mmmm...smells like pussy to me", I said, leering at her.

"Ohhh,...let me go...you...you", she stuttered, at a loss for words.

While she watched, I slowly stuck my tongue out and licked her finger. The one that only moments before had been sliding in and out of her cunt. Her eyes got wide and she sucked her breath in, in an audible gasp.

"What are you doing?", she breathed, barely audible.

"Just tasting my sisters delicious pussy", I whispered back, smiling gently at her, "Of course I'd rather taste direct from the source but that's up to you".

Her hand was clenched in a fist but as I slowly kissed and licked it, her hand opened up. I carefully took her index finger into my mouth and gently sucked on it, moving my mouth up and down the length of her finger. Her mouth opened and her breath was coming in jagged little gasps. She quickly looked over her shoulder to see if Mom was looking back at us and froze as if she'd seen a ghost.

"Billy,...Billy", she hoarsely whispered, "look...look what they're doing".

I looked into the front seat of the pickup and my eyes about bugged out. Dad had his arm around Mom's shoulders and his hand down the front of her blouse. I could see him squeeze her tit in his big hand then slowly pinch her nipple before rolling it between his thumb and fingers. Suddenly he just pushed down on the front of her low necked blouse and both tits flopped out in plain sight. Mom had her hand in his lap, slowly unzipping this fly. His throbbing cock sprang out of the opening like it was on a spring. Mom took it in her hand and briskly started pumping it, then dropped her head into his lap and swallowed his cock. Her head started to bob up and down rhythmically and the pickup jerked crazily from one side of the road to the other.

Jill was spellbound, watching intently as Mom sucked Dad's cock. Her breath was coming in ragged gasps and her hips were swaying to the rhythm of Mom's head. We were kneeling side by side watching the show being preformed for us. I laid my hand on the soft warm skin of her back and slowly pushed my hand under the waist band of her shorts. I caught my thumb in top of her shorts and slowly pushed them down over her ass, pushing them down till they were around her knees. My hand traveled back up her naked thigh until I was cupping her dripping pussy. Carefully I let one finger start stroking the length of her slippery slit, slipping inside her lips, searching for her clit.

"Ohhh Billy", she moaned softly, "just a little higher...ohhhh...right there...rub me honey...play with my pussy...aaahhhhhh slide your finger inside me Billy...please baby".

I slid my finger into her slippery cunt, picking up on the rhythm that Mom was using on Dad's cock. Her eyes were glued to the show Mom and Dad were preforming, so I eased my self back a little and let my other hand slip inside her t-shirt, caressing her tits as they swung to and fro with her gentle movements. I caught her nipple between my fingers and squeezed none to gently. A low moan escaped from between her lips, growing in volume as her climax approached. Suddenly she just collapsed on the carpeted truck bed, her body quivering as the throes of ecstacy washed over her. She rolled over on her side, looking at me through glazed eyes.

"Oh Billy...you made me cum...that's the first time anyone has ever done that for me. It was fantastic!", she said, "what can I do for you?"

"Same thing Mom's doing for Dad", I grinned down at her, scooting forward and pushing my sweats down around my knees. My cock sprang free, swaying and throbbing in front of her face as if it had a life of its own. Her hand reached for it, clasping it softly and guiding it toward her slightly parted lips. As her lips touched the silky skin on my purple knob, her tongue flicked out to catch the drop of pre-cum gathering at its tip.

"Mmmmm.", she sighed, "a little salty but I think I could learn to like this". She smiled softly and opened her lips and let my cock slide in. The inside of her mouth was like velvet, soft and warm, clinging to my shaft as I slowly stroked my tingling member into her steamy mouth. As I fucked her mouth I turned my attention to what was happening in the front seat of the pickup.

Dad had just shot a huge amount of creamy cum down Mom's throat and she was busily licking up what had overflowed onto his cock. When she had finished she sat back on the seat and with one finger cleaned a big glob off her cheek and slid it into her waiting mouth. Her tits were still hanging out in the breeze though she didn't seem to notice. As she relaxed back against the seat she turned and looked me right in the eye, then stared down at Jill, who was busily trying to get me off. Then she looked back up at me, smiled and blew me a little kiss before leaning her head against Dad's shoulder and snuggled up to him contentedly.

I was dumbfounded. Mom knew that I had watched her give Dad a blow job. She knew that Jill was sucking my cock. She knew I was ogling her tits. And she just smiled. Something was drastically wrong. Maybe I was having a dream. No, I could tell by the tightening of my balls and the jerking of my hips that the mouth around my prick was real.

"Omigawd Jill", I gasped from between clenched teeth, "I'm coming. I'm going to shoot this load right down your throat. Ohhhh, suck it honey. It feels so goood". My hips bucked and my balls tightened as I shot spurt after spurt of my hot sticky cum into her hungrily waiting mouth. I collapsed on the floor beside her, totally spent, trying to recapture my breath. I smiled down at her and ran my hand softly over her heaving tits.

"That was great, Sis", I whispered quietly into her ear, "maybe this vacation isn't going to be so boring after all." She smiled up at me and nodded her agreement.

Just then the truck started slowing down and Dad pulled it off the main highway onto a faint track that once was a road. After bumping along on it for a while, we pulled into a large meadow right on the edge of a lake. The grass was above our ankles and the fresh green leaves on the trees surrounding this verdant plain were ample proof that summer was truly here. Dad drove toward a big clump of trees by a small creek and found a long abandoned campground. He found a nice level spot and stopped our outfit. Jill and I were scurrying around trying to straighten up our closes and make ourselves presentable. Dad came to the back of the pickup and opened the tailgate and rear door of the shell and announced, "End of the line. All passengers will please get out", grinning at us all the time.

Mom came around the other side of the truck and said, "Well this is it. What do you think?"

Dad started to unhook the trailer and set up camp. Jill and I unloaded what we had to out of the back of the truck, set up the outside table and chairs and dug a fire pit, lining it with rocks we carried from near the creek. As we stood looking at the finished pit, Mom came walking up to us, Dad was still trying to get the trailer level and stabilized.

"Well kids, what do ya think?", she asked with a worried look, "do you like it? I think we can have a lot of fun here. Hardly anyone ever comes here any more." She moved closer to Jill and reaching up wiped a glob of sticky cum off her cheek. "Missed a little bit", she grinned, her eyes dancing impishly, "must have been in a hurry"

Jill's face went bright crimson and she stuttered and stammered something about it must have been some of the candy bar she had eaten but I stepped a little closer to Mom and reached out and wiped a big smear from between her tits, letting my fingers lightly stroke the upper slope of her tits as I did.

"Must be some of your candy bar", I said, looking her right in the eye, "would you like to finish it?" I raised my finger to her lips and she raised her hand and clasp mine, then slowly took my finger into her mouth and cleaned it for me, pursing her lips and running her tongue up and down it two or three times. My cock was throbbing, tenting my sweats out again. Mom just smiled and went to help Dad level the trailer. As soon as she moved away from us Jill turned toward me.

"She knows", she hissed, "what are we going to do?"

"Nothing. Lets just play it cool and see what happens."

"Okay, but she's sure acting weird."

I nodded in agreement and started gathering wood for the fire. I had a fire going, making a nice bed of coals for our tinfoil dinners, when Mom and Dad came walking towards us. We all drew chairs around the fire and sat and watched the flames for a few minutes. Mom cleared her throat and looked nervously at Dad, then turned back to us.

"Uh...kids...uh, there's something we want to ask you", she began nervously, "but first let me tell you a little about us that you probably don't know. A while before we were married, your Dad and I were naturalists or nature lovers as we were called back then. We liked to get back to nature, ya know what I mean?"

"Not really", I muttered as Jill and I both shook our heads no.

"Well, some people called us nudists, but we weren't really, we just liked to be out in the open country and not wear any clothes. Do you understand?"

"Yeah, I think so", I replied, glancing at Jill who was nodding in agreement.

"Well, ahhh, here's the question then", Mom said, glancing at us and then quickly looking back into the fire, "We were wondering if you kids would mind if we done that here, while we're on vacation?" She looked at Dad, who was just setting there, nervously kicking at the ground.

"You mean all of us?", I asked, incredulously.

"Well, we'd love to have you with us but we were just asking for us, if you want to that's something you'll have to decide for yourselves."

"I can think of one problem right away", I said, starting to kick the ground myself, "I ahhh,...I don't know if I could...Ahhhhh...get up and walk around, you know..." I looked at the ground between my feet.

"Oh", Mom giggled, "you mean because you'd probably have an erection?"

"Yeah", I mumbled, turning a brilliant shade of red. Mom was fighting to keep from laughing.

"What's so funny?", I demanded, glaring at her.

"Nothing's funny, baby", she giggled, "it's just that...well that your dad has the same problem. But after a couple of days you'll get used to all the naked females running around."

"Well, I guess if you don't mind me running around with a hard-on, uh, I mean an erection , it's okay with me. How about you?", I asked, looking at Jill.

"I guess it'll be okay", she replied, "but I think I'm going to be awfully embarrassed."

"You got nothing to be embarrassed about", I said, getting up and moving to her side. I tilted her chin up so I was looking her right in the eye and continued, "you have a beautiful body,...ahhh...what I've seen of it, and I know you're the prettiest girl in our school".

"Oh, Billy, do you really think so?", she exclaimed, beaming up at me, a smile lighting up her whole face.

"No doubt about it", I said, smiling down at her then glancing over at Mom. Mom was smiling too, a happy, contented smile that said she was proud of me and that this was going to be one great vacation.

"Well then, let's do it", Mom said happily. She stood up and moved a little closer to the fire, until she was right in the middle of us, then reached down, caught the bottom of her blouse and pulled it up over her head. She stood there a moment looking into the fire, then turned and threw her blouse on her chair and turned back facing me.

I stared. I couldn't help it. There was my mom facing me, naked to the waist. Her breasts pointed straight at me, almost defiantly. The perfect globes, topped with a dark brown aureole and nipples that protruded at least half an inch, sagged not at all. She raised her arms over her head, stretched and turned in a complete circle, letting us all feast our eyes on her body.

Then, after glancing over at Dad, she looked straight at me, hooked her thumbs in the waist of her tight, tight shorts and slowly began to push them down over her hips. She turned around, her back to me, then shifting her weight seductively from foot to foot, pushed her shorts down to reveal her soft full cheeks. My cock was pulsing in my sweats, moving the tent in them from side to side with each of its jerks. Turning slowly around until she was facing me, she bent over and pushed the shorts to her ankles. Her tits were swaying voluptuously as she moved her shoulders from side to side as she pushed the shorts to her ankles, then looking right at the quivering bulge in my sweats, she stood straight up, lifting her feet clear of the shorts as she did, and spread her legs wide.

"Okay, guys and gal", she said, "You've seen everything I've got. Your turn now Jim".

She sat down on a chair directly across the fire from me, her legs spread wide, the fire light flickering on the light blond hair of mons, glistening on the moisture seeping between the puffy red lips of her pussy. Her hand dropped down and one finger slowly began to stroke the gaping slit of those nether lips. Dad got up, his prick jutting from his shorts, and stood facing Jill. His hand moved almost absent-mindedly up and down the throbbing shaft of his cock.

"Won't take me long", he grinned, "you've already seen about every thing I've got." His hand moved to the snap on his shorts and in an eye blink his shorts were laying on the ground at his feet. He stepped clear of them and dramatically made a complete turn around, flexing his buttock muscles for Jills benefit. I looked over at Jill. She was mesmerized by the swaying of his huge cock, licking her lips as she brazenly stared at his throbbing member. I couldn't blame her. It was impressive. Must have been all of nine inches long with the purple cock head glistening in the flickering light from all the pre-cum that covered it. He backed up to his chair and sat down, spread his legs wide, and slowly stroked the length of his shaft.

"Your turn Billy", he said, grinning at me, "but only if you want to."

My Mom's eyes were locked on me like radar. She had a sexy little half smile on her lips as she watched me slowly get to my feet.

"I guess so", I mumbled, "I can't be the only one wearing clothes".

I quickly reached down and pulled my t-shirt over my head and laid it on the chair behind me. I paused for a moment, drew a deep breath and pushed my sweats and shorts around my ankles with one swift movement, then kicked my feet out of them. I stood straight and tall, my cock slapping against my belly almost to my belly button. Mom caught her breath with an audible gasp and her fingers sunk a little deeper between her lips. I wasn't quite as long as Dad, but was much thicker. The hair around my cock was thick and curly, light brown in color, the same as the hair on my head, and my balls hung full and heavy between my legs. My stomach was flat and rippling with muscles from my weight class, tapering up into well developed pec's and shoulders.
