Date: Tue, 16 Jul 2002 19:41:58 -0700 (PDT) From: Bruce Jenkins Subject: Naturally Curious, pt. 2 This story is half-fantasy, half-reality, based on the experiances I had with my family. Names and places are fictional to protect my perverted ass. Enjoy! ____________________________________________________________ My name is Brian Jensen. My childhood was not a normal one, and my family was much closer than most. Like the man said, people aren't homosexual, or heterosexual. People are just sexual. I love cocks, and I love pussy, and this is how it started.... _____________________________________________________________ I have mentioned that I lived on a rather secluded farm in Iowa at 10 years of age. My adopted brother, Jacob, and I spent that summer building a treehouse fort in a large grove of trees that our property shared with our closest neighbor. As my Dad owned more than 500 acres of land, and Mr. Norton, our neighbor had about the same size place, we had the privacy to keep this a secret. At 7 years old, Jacob wasn't much help, but I wanted to keep this fort for boys only. My sisters, Heather and Grace, were not allowed to know about our fort. It was my idea, and I made Jacob swear everyday that he would not reveal it's location on the pain of death. He was in proper awe and excitement over the project, as only a 7 year-old can be. The summer heat was dampened under the trees, but not entirely. I took to working in a pair of shorts and sneakers, without shirt or underwear. Jacob did the same. A brook ran clear water through here, and we would often splash around in the water to cool off. Underwear would just get wet and chafe. It was a wonderful summer, one of the best in my life. We had started our mission about 3 weeks before Dad had shown us how to clean our penises. The morning after, I woke with a relaxed feeling in my loins and a smile on my face. The clock read 7:30. The house was still. My father had put a partition in our large bedroom, separating our beds and dressers, giving us a little privacy. I couldn't see my brother, but I could hear him snoring. I let my thoughts roam, thinking about what had happened last night. Erotic thoughts led to a morning hard-on in very short time, and soon my sheets were tented up. I flexed my legs and groin. My 5-inch cock jumped, it's head rubbing against the soft flannel. I needed to pee, so I got out of bed, and put on underwear. I could barely cover my dick, it was so hard. Finally, I tucked it in, my cockhead sticking out the bottom. As the elastic of my briefs pulled on it , the red color of it deepened. The house was still quiet, so I silently opened to door and stepped into the hall. Our bedroom was on the 2nd floor, sharing a balcony with my sisters' bedrooms, at the other end. They didn't have to share rooms. My mom said when I was a teenager like Grace, I could have my own room, too. And she said Heather, my 9-year old sister, shouldn't share with boys 'cause we played too rough. I peeked over the edge of the balcony into our living room. My parents bedroom door was off to the side, still shut. They were asleep. The bathroom was in the middle of the hallway upstairs, dark and empty. I had no idead how I was going to force piss through my hard dick, but I had to go. I freed my straining cock and lifted the lid on the toilet. Pushing hard, I was able to spurt out my urine in bursts, until it got going. It felt great, almost as good as cumming last night. Just then, the door opened and Grace, my 13 year old sister burst in. She had long brown hair, an athelic, slim, deeply tanned body with a skinny farmgirl look to her. Her breasts were conical, pert B-cups that had just started to develop about a year ago. I couln't have been more embarrassed, and I turned red in milliseconds, as her eyes locked onto my hard dick spraying piss into the bowl. "I'm so sorry to barge in. I gotta go , too." She tore her eyes from my cock to look at my face. I noticed that she was blushing as furiously as I was. "Sorry, I couldn't help but look." . She was wearing a little white tanktop, white cotton panties and nothing else. I could see the outline of her little nipples. Her breasts looked huge on her small 5'1" frame. "Well, gimme a second and I'll be done, if you are in such a hurry," I said. I finished and tucked my dick in as she turned her back to respect my privacy. Pissing had softened my dick a little, and it no longer stuck out the bottom. I was still sporting an impressive bulge, though. "What time will your ride be here?" I asked, trying to sound casual as I stepped over to the sink to wash my hands. She babysat 3 kids in town during weekday mornings. Thier mom, Mrs. Jordan, taught summer school, and Grace usually left the house by 7 a.m. "No school today, the air-conditioning broke," Grace replied. "Don't look-I'm peeing." There was no better way to get me to sneak a peek than by telling me not to look. She didn't normally pee with us in the bathroom, I knew she was doing it so that I wouldn't be embarrased about her walking in on me. Gracie was cool like that. Out of the corner of my eye, I watched as she schucked her panties down, exposing her white, triangle shaped tan line. Her pubic hair was more dense than mine, a wide strip above her developing vagina. She sat down quickly, her nipples even more pronounced than before. I had finished washing my hands, and had no excuse to stay, even though I wanted more than anything to finish watching her pee. As I walked past her, turning slightly to hide my bulge, she said,"Come here a second, Brian." I froze, nervous and excited at the same time. I felt very vunerable after what she had just seen, but my hormones won. I turned toward her, and my dick stiffened a little more. The tip poked out the bottom, and I could feel the rest of my cock head straining to get out. She was smiling, and my eyes dropped down to her pussy as a stream of urine split her pussy lips. They were covered in blondish peachfuzz, very short, but very soft looking . Soon, she would have a very hairy pussy, but for now I could see her girlish labia and her red slit between. My face was flushed, and my boy cock was rock hard. "Mom said that you would be going through puberty soon." Her nipples were now fully erect, and I could see the outline of her areolae through the tight top she had on. She motioned me closer, the stream of piss still splashing in the bowl. As I stepped forward, the motion caused my cockhead to spring past the elastic. I pulled my briefs to cover it. "It's o.k. I won't make fun of you. Can I see it again?" she asked, leaning to reach the toilet paper next to her as her pissing subsided. I nodded and pulled down the front of my briefs. She looked at my cock for a long moment , then wiped the piss off of her pussy, mashing her pussy lips down with the paper. "I know how to cum," I blurted out. "Do girls cum like boys do?" I could imagine jizz squirting out of her pussy like the stream of urine I had just witnessed. "No, silly, girls don't have a penis. We cum different." Kicking her panties aside, she spread her legs, straddled the toilet, her pussy lips separating as she moved. Her inner pussy was delicate and perfectly formed, ruby red and still glistening a little from her piss. Her clit was sticking up, a small button and redder than my cockhead."See, we just have a clit. It's like a nipple on our pussy." She gave it a little rub. "I think mine looks like a little penis head." "Does it feel good when you touch it? Mine feels great when someone else touches it, is it like that?" I leaned in for a better look, kneeling on one knee. It did kinda look like a small dick. "Girls are the same way," Grace said. She smelled wonderful, like musky flowers. "Go ahead, touch it." I reached my hand in, and with one finger, rubbed her hard little clit for a second. She inhaled sharply and smiled. Suddenly, I heard a thud from my bedroom, then a door open. Our voices must have woken Jacob. I stood quickly and started to pull my underwear up. I was still bent over with my briefs below my knees when the bathroom door opened. "You guys are loud in here. What are you doin'?" His 7-year old body was naked, and his balls were pulled tightly against his uncircumsized Asian little boy-cock. He didn't always sleep naked, but last night was a special occasion. Grace stood, her panties still on the floor. "Sorry, squirt, we were just peeing. Didn't mean to wake you up." She bent over, her perfect slim 13-year old ass turned to us to pick up her underwear. Her pussy mound stuck out from underneath it, her puckered hairless asshole a pinkish color and we were both stared. She pulled them on tight, outlining her pouting pussy lips and covering her hairless buttcrack "How 'bout it , Jacob? Do you need to go, too?" she said. Jacob nodded, yawned and stepped over to the bowl. Grace was checking him out the whole time, as fascinated as I was by his little uncut dick. The piss jetted through the tip of the conical foreskin, his tiny, atheltic butt turned toward us, just a shade lighter than the rest of him. He finished, and noticing us staring at him with smiles on our faces. He smiled back, came over to Grace and hugged her waist, his face level with the bottom of her tits. "I love you, Gracie," he said with the innocence of a child. His soft cock rubbed up against her leg and she touseled his hair. "C'mon , squirt, let's get some clothes on you." She took his hand and I followed them to our room. We dressed quickly, me trading underwear for a pair of shorts, my hard-on easing as I went about my normal routine. Grace picked out a t-shirt and shorts for Jacob, and we all went downstairs to have some cereal and watch cartoons. Grace was still in her panties and tank top, her little ass prancing about as she got the bowls out of the cabinet for us all. As Grace and Jacob sat on the sofa, ate and watched T.V., I stared at her nipples showing through the thin fabric of her tank top. She caught me looking after a moment, and slowly thrust her chest out to show off her developing breasts. "You know," she said teasingly,"if you stare at girls chests all the time, people will think you are a pervert." She shrugged her shoulders back and forth, making her boobs rub against the fabric of the tank-top. "That's mean! I can't help but stare, your nipples are poking out!" I defended myself, still staring. She looked down at her chest in mock surprise. "Oh, my! They are....what's the matter? Does it excite you? Are you getting another boner?" As a matter of fact, my dick was growing again, spreading warmth through my body. "I thought you weren't gonna tease me about my boners. You said you wouldn't." I didn't really care that much in front of Jacob, but she had said that it was o.k.when I got hard. "I never said I wouldn't tease you, just that I wouldn't make fun of you. It's different , ya know." Her eyes were a little glazed, and her nipples were hard tips now. The phone rang, jolting us back to reality. Grace hopped up for it, bouncing delightfully, but it stopped ringing before she got there. I heard Mom answer it, her voice muffled through the house, first tired, then a little more urgent. A couple of moments later, she and Dad strolled into the living room. Mom was wearing a tennis skirt and t-shirt with a ballcap. Her 5'-2" frame was a tad bit heavyset, but not chubby, with D-cup breasts and well proportioned legs and butt. Dad was still in his pajama bottoms , with no shirt. His 6'-2" frame was imposing, with a farmer's tan, solid muscles and dark hair. He smiled and winked at us kids as Mom spoke. "Good morning, kids. I got called into the club. I will be back this afternoon. Be good for your father." Mom filled in at the athletic club about 25 miles from here as a tennis instructor. She had been Iowa state champion when she was younger, and was still pretty athletic. She kissed Dad goodbye and was out the door in a flash. "Well, it looks like I'm mom for the day," Grace said. She smiled at Dad and said," Do you want some breakfast, Daddy? I can cook you some eggs if you want." "You are so sweet this morning, I think I will just have a bite of you," Dad joked. He grabbed her arm, pretending to munch on it, slobbering and gnashing his teeth. "Oh, gross! Daddy, stop it...!" Grace couldn't help but giggle. Her nipples were still hard, and I noticed Dad's eyes were on them. "Daddy, if you aren't good, I won't cook for you!" "That's o.k., sweetie. I think I will just have some cereal and watch cartoons with you guys until I wake up a little. Can you get me a bowl of it when you take your dishes into the kitchen?" We finished eating, and Grace took the dirty dishes into the kitchen as Dad eased into his Lazy-Boy. Grace brought him back in a bowl of cereal, her breasts bouncing under her tank top as Dad stared. She leaned over Dad as she set the bowl down, her young breasts inches from his face. I noticed a growing bulge in Dad's pajamas. We heard a door open upstairs, and a moment later Heather came downstairs, her fine, blonde hair a mess, her 9 year old body clad in her nightshirt. She was about my height, and had not yet begun to develop, but she had the sweetest face and big blue eyes that could melt you when she smiled. She yawned, smiled, and went to the kitchen. Dad spoke up. "You kids need to be sure to finish your chores before you do anything else today. Please do a real good job. Your Mom has a long day today, and I want her to come home to a clean house." He shifted his position to hide his bulge as Grace trotted upstairs to change, her firm ass hanging out of her panties, her tanline cutting a light swath against the outer part of her buttcheeks. Jacob and I exused ourselves to clean our room, then we fed the animals (we had dogs, cats, chickens, a couple of horses , and several other pets) while the girls worked on cleaning up the house. We finished in about an hour, and snuck off to work on the tree house about 9 am. The day was already hot, and we were sweaty from doing our chores, so we took time to splash around in the creek to cool down. We were playing in the water, relaxing and talking about what additions we would make, when our privacy was interupted by footsteps crashing in the brush. Both of my sisters came into view, smirking. Grace had put on a bikini top and jean shorts, and Heather was wearing her swim suit, a pink one piece that was a tad bit snug. "What are you two doin'?" Heather asked. "Is this where you guys have been sneakin' away to?" She noticed the half-finished fort in the lower branches of the tree. "Neat, can we help?" I was furious. This was supposed to be a boy's only treehouse, and now the secret was out. "No, you can't help. This is a boys club. Girls aren't allowed." They looked at each other and laughed, making me madder.. Grace spoke up. "Well, not anymore. C'mon, Brian, we can help. You can even be in charge. We can finish faster if all of us help." It made sense, but I was still pissed. "No, absolutley not. No girls." I stood my ground. "Please, Brian, don't be mad," Heather looked at me when she spoke, her angelic face framed in blonde hair, and I melted a little. "We will do everythng you say, really." I caved. "Well, o.k. But I'm in charge, and you guys have to take the oath of secrecy. Get up in the treehouse." They smiled, and began climbing. Heather was first, her smooth little 9 year old butt flexing through her swimsuit as she climbed up. It was a hand-me-down from Grace. As she climbed, I could see the fabric working its way in between her pussy lips. Grace followed , then Jacob and I. We had finished the treehouse floor a couple days ago It was just big enough to hold us all, but it creaked a little. I could see a little doubt and fear on the girls' faces and decided to play this up. "Everyone, sit down in a circle, crosslegged, boy-girl, boy-girl. We will now take the oath of the Jensen's Secret Treehouse," I said , deepening my 10 year old voice as much as I could. We arranged ourselves in a small circle, sitting cross-legged. I decided to milk this for everything it was worth. After all, if this wasn't going to be a boys only club, I should get to have a little fun. "Close your eyes, everyone. Place your right hand on the shoulder of the person to your right" After making sure everyone's eyes were tightly shut, I groped for Heathers shoulder as I felt Grace's hand on mine. " Now,when I tell you to, place your left hand over the heart of the person to your left. If it skips a beat during our oath, you will know that person is lying. If you lie about keeping this place sacred, you will burn in hell. Slowly, place your hand over thier heart now." I was making this up as I went along, but I wanted this to remain a secret. No more outsiders needed to know. Besides, doing it this way, I would get to cop a feel of Gracie's chest. She had been teasing me all morning, so I thought this was fair. I felt Heathers hand creeping along my chest, unsure where my heart was and I reached over to my left. My hand first grazed Gracie's stomach, and I slowly moved it up, applying pressure as I went. I felt her sharp intake of breath as I touched the bottom of her firm breast, and my hand caught in her thin bikini top, lifting it slightly. I felt the flesh of her tit, warm on my hand , smooth and soft. She shifted slightly, pulling up so that the fabric once again rested on her skin. I moved my hand up, cupping it slightly, and I could feel her nipple through the slick cloth of her top. Blood rushed to my penis, and I reluctantly moved my hand over her heart. It was thudding in her chest, just as mine was. Heather broke the spell. "Now what?" she said. I cleared my throat. "Quiet. Do not speak unless I tell you to. Repeat after me. 'I promise, even if tortured, never to tell about the secrets of the treehouse.' " They slowly repeated my words in unison, and Grace shifted under my hand again, sitting straighter. I felt her push her chest out and lift it, bringing the top of her cleavage into the palm of my hand. My semi-hard dick grew a little more, and I was having trouble concentrating on anything but the soft breast beneath my hand. She was doing it on purpose, to distract me, and it was working. I tried to clear my head, but I had never felt her up before. It was driving me crazy. " ' If I do tell, I understand that I will never be allowed to come back.' " As they repeated the words, I let my hand fall down the front of her top just a little more, and inched my pinky down under her bikini top, until I made contact with her nipple. It felt like a hard nub , especially next to the soft flesh of her perfect young tit, and my boy cock sprung to full attention. " 'No matter what happens in the treehouse, it will always stay between us.' " Now I was really winging it, the words brought on by hormones, but everyone repeated them as I withdrew from fondling my sister's B-cup breast. I opened my eyes. Jacob was peeking with one eye, looking at the hard nipple showing through Gracie's bikini. His eyes popped open when he saw me looking at him, and then he looked at my crotch. My wet shorts covered my hard on, but it was very visibly tenting my shorts, its cockhead outlined. "Keep your eyes shut, please." Jacob closed his again. I left mine open. The girls had never peeked, it seemed, so I continued. "Slowly remove your hands and place them in the center of the circle." As I did so, I adjusted my hard penis, making it less obvious. We all piled our hands in the middle. "Repeat one last thing after me. ' I so swear.' " "I so swear," they chorused. "Open your eyes now," I said. Grace opened her eyes, and they darted to my crouch. "You just did that so you could feel me up!" she said, smiling. Heather looked at Jacob, confused. "Did what? What did you do, Brian?" She hadn't peeked after all. "He was feeling on my boob. See, he made my nipple get hard and everything." Grace pushed her chest out, looking sexy with one rock hard nipple and one that wasn't. "Yeah?" I replied. "Well, you liked it. Would you like me to play with the other one now?" I pointed to her right nipple and smiled. She pointed back at my dick. "You need to control yourself. If you keep walking around with a boner, you will never get a girlfriend." Heather looked over at my crotch noticing my bulge for the first time, and piped up in her sweet, high pitched voice. "I never saw a boy hard before. Why does it do that?" she asked. Jacob answered her. "Daddy says it does that when you are having fun naked. I can get mine hard, too. Wanna see?" Grace looked over, a quizzical expression on her face. Jacob had almost let the cat out of the bag. We were sworn to secrecy about playing with Dad's cock last night. She let it pass and said," Heather, you should see them both. Brian's is bigger, but Jacob's looks neat, with all that extra skin on it. I saw them in bathroom today." My jaw dropped. She smiled. "C'mon, we are sworn to treehouse secrecy. Let her see your penises." Jacob had no reservations about getting naked, and he stood and pulled down his shorts, his little uncircumsized cock still soft. "Jacob, its not hard. I thought you said it got hard." Heather had seen him naked many times before, but now it was different. It was like playing truth or dare without the questions. She looked over at me and said," Is he lying? Does it get hard?" "He's not lying, he just needs some help sometimes. Jacob, show her how you play with it to get it hard." Jacob began playing with his foreskin, pulling it down to reveal his glistening, pink cockhead, and then covering it again. Heather looked on, only an arms length away, fasinated. Jacob"s cock was growing a little, but mine was still trapped inside my shorts, straining at them. I felt Grace's hands on my waist. "Stand up, I'll help you get your shorts off. We wanna see yours, too." I stood, and Grace slipped my shorts down from her seated position, freeing my cock. For the second time today, her young face was just inches from my penis. It had soft, dark hair at its base, with smooth, hairless balls. My cockhead was deep red and at 5 inches, it looked huge for my 10 year old body. "It looks so cool,"Grace said. Her hand reached up and she gripped it for a moment, her hands hot on my stiff, little rod. Pleasure ran through my body, and I jerked my hips a little. "Turn around, let Heather see it," she said. I turned , my cock eye-level with Heather as well and her jaw dropped. "Wow, that is big." Her pretty little face had a smile on it. "I'm gonna touch it, too, o.k.?" She reached her hand up, and stroked the bottom of my shaft. Her small hands fit perfectly around it as she explored my hard penis. "If I was a boy," she said,"I would always be playing with myself. That is so neat." Heather glanced over at Jacob, who was still trying to get hard. "He may need a little help," I said. "His is still small, and they don't get hard as easy, I guess." "Would you like our help, squirt?" asked Grace. Her other nipple was hard now, too, and I knew haveing our penises out was exciting her. Jacob nodded and Heather reached over to his Asian cock. She toyed with it inexpertly as he smiled. Her little hands looked big next to his undeveloped penis. She wasn't having much luck. Grace reached over and cupped his smooth ballsack in one hand and mine in the other. Stroking gently for a few moments did nothing to help Jacob, but I felt like I was going to explode. Grace spoke up. "I know a way to get a boy hard. Bobby showed me." Bobby Burtly was a 15 year old that lived about a mile down the road. "Look, sis, I'll show you on Brian. Then you can do it to Jacob. He will like it. Trust me. Bobby loves this." She grabbed my dick and pulled me toward her. Gripping tight, my cockhead turned an even deeper shade of red. "See, first you kiss it for luck." With that , she planted a wet kiss on my cockhead. I had never had anyone kiss it before. It felt warm and wet, and I loved it. Heather looked at the little pink cockhead on Jacob's dick and did the same. Jacob giggled. "Then, you stick out your tounge and pretend it's a lollipop." She stuck out her tounge and rested my cockhead on it's warm wet surface. Slowly, she began rubbing my cock back and forth across it. I was in exstacy, my blood pounding into my penis, her tounge soothing my hot cockhead. Heather did the same to Jacob, and in moments he was hard. Heather stopped and began toying with his hard little penis, playing with his foreskin, but Grace kept going on me. My heart was pounding, I could feel it throbbing in my cockhead. Grace stopped long enough to say, " Heather , watch this," and closed her mouth around the head, using her tounge to flick at it while sucking. I had never cum before last night, and even then I needed Dad's help. Not this time. Grace must have felt the spasm of pleasure that racked my body. She pulled her head away from my cock, and pointed it away from her face, toward her chest. This time, there was less fluid, but it still felt great as my clear jizz erupted out the end of my penis. It landed on her bikini covered breasts, and ran between her cleavage. My eyes were shut in and I could hear a buzz in my ears as I ejaculated. It was spectacular, better than masterbating by far. "Oh, gross, did you pee on her?" asked Heather. I opened my eyes. Drops of cum had made wet spots in the front of Gracie's bikini top. One was right on her hard nipple, and I could see the puckered texture of it through the thin fabric. Heather let her hand slide from Jacobs hard little dick, and peered at the liquid. "No, it's not pee," I said. "It's cum." "Don't worry, Heather. It's what guys do when they have hard ons. That's how they make babies. It's not like pee at all. See?" Grace swiped some from between her boobs, and touched the end of her tounge to her finger. "It tastes kinda wierd, but not like pee." She held her finger out to Heather , and Heather licked it. "Can I try some?" Unlike Heather, Jacob had his first taste of my cum last night. Grace swabbed some more off, and Jacob licked it. Gracie then offered her finger to me. I didn't hesitate, I was curious to see what I tasted like. It was kinda slimy and salty and manly all at the same time. I pointed to Grace's top. "Sorry about that," I said. " We can clean it in the creek." I was finally going to get a good look at her tits, and the thought of it made me semi-hard again. Gracie smiled at reached a hand behind her, undoing the knot that was holding on her top. The strings fell down to her side, but her firm breasts held the bikini on. Slowly, making a production of it, she peeled down her top to reveal her tanline, stark white against her tanned torso, very faint blue viens visible on the fair skin. She peeled futher, and all of us were watching. Her pink nipples popped out, like little pencil erasers, and I marveled at them. They looked like her clit, but bigger. She still had some cum between her tits, and she used the bikini to wipe it off. Heather looked at her own flat chest , then back at her sister's, and sighed. "I can't wait to get boobs. Your's are perfect, Gracie. They are gonna be bigger than Mom's." Grace smiled and stuck her chest out proudly. She reached up and pulled on her nipples a little. Jacob reached over and poked at it. "Not like that, squirt. You have to be gentle." "Like with Daddy?" Jacob replied. I cringed inwardly. That was a major slip. I couldn't tell him not to say anything, that would just make them more suspicious. "What do you mean?" asked Heather. "Daddy doesn't have boobs." Jacob smiled and said,"I know. His penis, though. You have to be gentle with his penis." Heather and Grace sat there with dropped jaws for a moment. It looked like an X-rated version of "Kids Say the Darnedest Things", with Jacob and I naked, Grace topless and not a word was spoken for several moments. Jacob looked at the floor, knowing he had let a big secret out. Grace spoke first. "Jacob, when did you play with Daddy's penis?" "In the shower." "Was it hard or soft?" "It was hard, and it's so big, bigger than Brian's and mine put together." "Did he touch you, too? When was this?" Jacob looked over at me, a little ashamed. He was too little to know that playing with Dad's cock was wrong, but he sensed that the girls were a little freaked out. I had to step in. I didn't want them to get the wrong impression. "It was last night. It was no big deal. It was a boy's only talk. Dad was just teaching us some stuff about penises." There was alot more to it than that, but that was all they needed to know. "It was supposed to be a secret, and under the rules of the Jensen Treehouse, you are both sworn to secrecy, o.k.?" I looked from one to the other, and both girls nodded. Grace smiled impishly. "I bet Daddy would show me his penis, I've seen the way he looks at me. If I asked him to show me, he would. How big is it?" Her eyes were a little glazed over, and I realized that if I got horny at 10, she must be ready to explode. My dick got a little harder thinking about it. " He is about this big," said Jacob, and held his hands about 2 feet apart. "He is not," I said. "He is about about as long as this." I grabbed Grace's bikini top, still damp from my jizz and marked off Dad's length for them. I noticed that Grace had a tiny wet spot between her legs on her jean shorts. I figured I must have shot some jizz there , too. "Gracie, I think some of my jizz must have gotten on your shorts, too. We better wash them when we wash your top." Grace looked down at her shorts, and unbuttoned them. A musky, female aroma filled the air, and I could see her pubic hair. "That's girl jizz, not boy jizz. It's mine. When girls get excited, they get wet down there. Wanna see?" She wriggled out of her shorts and tossed them aside. The peachfuzz on her pouty pussy lips was damp with moisture, matted down. Heather looked closer, the only one of us left wearing clothes. "I don't have any hair on mine, and I don't get wet when I play with it. But it still feels good." She must have felt out of place with the rest of us naked because she slipped out of her swimsuit, revealing her smooth, fair body. Her chest was flat, almost like a boy's , but with a little extra meat where her breasts would soon start growing. Her slit was hairless, and her labia were large and smooth. I wondered if it was red inside like Grace's. Heather reached over to Grace's pussy. "I wanna taste your jizz, too. Does it taste like Brian's?" Grace smiled, her eyes glazed , as our little blonde sister rubbed her fingers over Gracie's hot, damp pussy. "No, honey, it tastes like a girl," Grace said. I reached in , too, and Heather's hand and mine touched as we rubbed Grace's slick, wet 13 year old twat. I pulled my hand away, and offered it to Jacob. He eagerly licked the wetness from my hand. I rubbed Grace's pussy again, this time spreading the juices over her clit before gingerly putting my hand to my face. I tasted her clean female jizz and my dick got rock hard again. Soon all three of us were gathered around Gracie's pussy, stroking it and tasting it. I let one hand roam to her breast, squeezing the turgid nipple in my fingers. She was in heaven, with six hands roaming over her almost grown-up body, getting hotter by the moment. My hard cock rubbed against her leg, and she reached down to play with it. "Oh, my, this is more than I can take," she gasped. "Jacob, why don't you play with Heather's coochie, while I show you guys what adults do." Jacob and Heather backed off a little and Gracie, still holding my cock, whispered to me," I 'm going to let you put it in me. It feels great, but you have to go slow." I was amazed that she wanted me to do this, and unsure of what to do, but very willing. "O.K.," I whispered back. She released my cock, and guided me on top of her. Jacob and Heather weren't paying a whole lot of attention, each one was playing with the other. Heather leaned down and kissed Jacob's penis and rubbed it on her tounge, the way she had learned earlier. Jacob was soon hard, and when she stopped, he leaned over and kissed her hairless slit and began licking it. I felt Gracie's hand on my penis, and she guided it toward her hot, wet hole. I was rock hard, but I didn't think I could cum again so soon. Grace rubbed my cockhead over her clit, arching her back , sending spasms of pleasure through both of us. I could feel her soft pubes on my head as she rubbed it up and down. Then she slid it a little further down to a small, tight opening in her slit. Slowly, she eased herself toward me, the sides of her slick pussy hot against my throbbing cock. Her boobs were right in front of my face, and I couldn't help myself. I kissed her hard nipple, and took it into my mouth. It felt so natural, like I was breast feeding, sucking on my sister's hard nipple with my dick inching up her tight pussy. Jacob had stopped licking Heather, and they were both concentrating on us, fondling each other, his hairless Asian skin looking very dark next to her fair , smooth body. Grace got my entire cock in her, her little pussy was so wet and tight around me I was sure she could feel every vein in my boy-cock. She began moving, sliding my cock inside her, and the heat and moisture were more intense than ever. She reached a hand down between us, and began to play with her clit, while I took her other nipple in my mouth and sucked on it. I could feel how hard she was rubbing her clitty, keeping rhythm with my strokes. My hairless ballack slapped up against her, and she began to quiver. Gasping in uneven breaths she said,"OH....I'M GOING...TO...CUM!" I felt wetness spurting me, hitting my cockhead first, and oozing out her pussy. There was a lot, more jizz than I had, and it pooled under her pussy. Grace shuddered and gripped me tight. I felt like she was going to break me in two, she was clinging so tight. Jacob's voice rang out," She is peeing!" Grace released me, and I reluctantly removed my hard cock from her wet vagina. The floor had a huge puddle on it, and it did look like pee. "Wow," she said. "That never happened before. Usually, I just get real wet and it feels good. That was the best ever!" We were too young to know about squirters, and thought this was what all women did. "That's pretty messy," said Heather. "Mom and Dad must wash thier sheets all the time. Or maybe they do it in the bathtub." Grace giggled, looking beautiful, laying naked in a pool of her own girl-jizz, her body covered in a light layer of sweat, making her glisten. Her bare breasts were wet with my saliva. "We should get back, before Daddy notices that we are all gone," she said. "Remember what Brian said, this is our secret treehouse, so don't tell anyone what happens here. Right, Jacob?" We all looked at him and he blushed. "I really , really promise this time. I won't tell no one. I promise." He was so cute, his little cock still hard from Heather's attention, and I gave him a hug. Heather and Grace joined in, and we hugged each other, naked, for a moment. We all splashed naked in the creek for a few minutes to cool down, and cleaned Gracie's jizz covered clothes. We had used her shorts to clean up her cum, and ran cool water over our bodies while the clothes dried. Everyone was still feeling everyone's privates, it was a fun game, and one that would last for a long time in my family. When we all returned home, Dad was changing the oil in his tractor. It was hay season, and he would begin baling it up next week. We would have to be careful, I knew he often used the creek to cool off in when he got hot in the field. The more I thought about it , though, the more I was sure he wouldn't be mad if he caught us playing naked. I would just have to wait and see....
