It blew my dirty-blond hair about and made me shiver a bit as I walked along the rocky beach. Ahead of me by thirty feet or so was my sister, Ashleigh. She was twenty and in her second year at art college. This year she was taking a course in jewellery making. Her latest phase was fashioning rings, broaches and pendants out of pewter with beach glass embedded in it. That was what had brought us to Watkins Beach on a Sunday afternoon in July. Ashleigh was not just my sister -- she was my twin, born almost five minutes ahead of me. I often joked that I gave her a kick in the ass to get her moving because I wanted to get out to be fed. My sister resembled me, but were we not the same age few would guess that we were twins. After my last growth spurt I had reached just under six feet, which was a good six inches taller than my sister. While my hair was a murky, brassy colour, Ashleigh was adorned with golden, natural curls that trailed down past her shoulders by several inches. Her eyes, like mine, were hazel, but unlike mine, hers sparkled with a vitality that was captivating. In addition to these differences Ashleigh was also blessed with a distinctly feminine body. Everyone took notice of this fact, including me. "Hey, Bryan, I found some more!" Ashleigh called out to me, obviously excited. I walked over to where my sister was, just a yard or so above the water lapping at the sand as the tide came in. Amongst the rocks and kelp I saw pieces of green, brown and red glass. Ashleigh was gathering them up and depositing them into a plastic bag in her hand. "Look -- some blue pieces. That's rare," she said, sounding pleased with her find. I squatted down beside my sister and began plucking pieces of glass from the damp sand and dropping them into the bag. Her hair was being blown about by the wind off of the bay. It brushed the side of my face, tickling me. I pushed it aside. "What?" she asked, looking up at me. "Your hair's in my face," I said. Ashleigh pulled her corkscrew-blond hair back over her shoulder, then continued picking up the glass shards. She was wearing black shorts, sneakers and a navy blue tank top. Her top had a V-neck and narrow straps. It hugged her body, emphasizing her flat stomach and bustline. As I bent down to pick up pieces of glass my eyes strayed to the front of my sister's tank top as she crouched beside me. I looked at her breasts, half exposed in the V-shaped neckline as she leaned over. They swayed a bit as she moved. They were round, obviously more than my hands cold hold, and firm looking. Her skin was tanned and smooth. It looked like it was still as soft as the day we were born. She smiled up at me. "Quit staring at my tits and pick the glass up, Bryan. I want to get home so I can wash this stuff off and sort it out." I smiled at my twin sister's scolding and shifted my focus back to the glass at my feet. Most brothers would no doubt be embarrassed or shameful at having been caught leering by their sister, but I wasn't. Ashleigh and I had a special relationship --although most would consider it unsavory, to say the least. Growing up with a twin meant that I always had a best friend. When we were young there was no gender difference between us. Ashleigh was a tomboy and interested in many of the same things I was. We were always one another's confidante's and support system. Once we reached puberty some things changed, both about us as individuals and with regards to our relationship. I was given my own bedroom and my sister became modest about allowing me in her room, depending on what she was wearing. Eventually I began to take notice of the physical changes in Ashleigh. It was then that I also began regarding her as a very pretty girl, in addition to being my sister. She began to notice me in the same way too, although I did not realize that just yet. "Let's go sit down. I want to look this stuff over," Ashleigh said. I trailed behind my sister until she found a flat rock and sat down. I joined her on the rock. She was peering into the bag, as excited as we were as children on Halloween, rifling through our treat bags once we got home. I looked over her shoulder at the bits of coloured glass. Her hair was lashing my face once again and I pushed it aside. She smiled. We sat shoulder-to-shoulder as she examined the haul of glass we had gotten. The wind had seemed to have picked up. I wrapped my arms around myself and leaned over, trying to keep warm. I noticed that my sister's nipples had reacted to the chilly breeze too. They stood out firm from the curves of her breasts, making two bumps in the blue material of her top that were almost as big as the tip of my little finger. I stared, trying to imagine how they would feel pinched between my lips. "Can we get going, Ash? I'm freezing," I said. "Aww... is my baby brother cold?," she said with faux sympathy. "Here, let your big sister keep you warm. I swear, you'd have died years ago without me around." Ashleigh placed the bag of glass down on the rock beside her and wrapped her arms around my shoulders. She pulled me to her, holding me tight against her warm, cushiony chest and rubbed my back through my t-shirt. My sister relished playing the role of protectress and reminding me that she was five minutes my senior on every opportunity she got. Her body was warm and and felt wonderful as she held me tight to her. Her breasts were firm. She wasn't wearing a bra, so they moved freely beneath her top and rubbed over me as she moved her shoulders. My arm slipped between them as she shifted, making herself comfortable. "Better? You warm now?" she asked, her hot breath teasing my neck. "Yes," I said, nodding. "Can you hold me till it gets about ten degrees warmer?" Ashleigh laughed. "No, we have to get back home. You'll have to get your cheap thrill somewhere else today, little brother." Ashleigh let go of me and picked up her bag of beach glass. She stood up, extending her slender hand to me. She pulled me to my feet and tugged me towards the bank leading up from the beach to where our car was parked. As we navigated our way along the beach over rocks and through sand Ashleigh kept hold of my hand. Part of the reason was to steady herself as she stepped over water-weathered boulders, but it was also part of our spontaneous, habitual closeness. Had anyone seen me and my sister they would have assumed we were lovers. Had they known that we were siblings, they would have found our hand-holding odd at best. Neither of us cared. It was something that had developed naturally, but was never spoken of or discussed. I think that acknowledging it would have somehow broken the spell and made it seem less special. The other reason could very well have been because we both knew it was unaccepted and forbidden by convention, so we did not want to analyze it. Still, physical closeness that at times bordered on intimacy and good-natured jibes from her about me ogling, or being aroused by her, were commonplace between us. It was just how things had evolved with us since adolescence. It never felt unseemly or unnatural to me or Ashleigh; quite the opposite, in fact. I was glad to be back in our warm car as Ashleigh drove us back home. The car was a blue 2003 Honda that our parents had bought us a couple of years previously as a birthday gift. We used it mainly to get to school and our respective jobs, although we occasionally squabbled over it when our schedules conflicted. Ashleigh had the radio turned up loud so I stared out of the window and didn't bother initiating any conversation. Once we got home Ashleigh went straight up to her room with her bag of glass. I made a sandwich and poured myself a glass of pop. After I finished eating I went up to my room to download some music and play video games. Mom was busy outside in her flower garden and our dad was out somewhere, probably golfing. I could hear music coming from my sister's bedroom. About fifteen minutes later she wandered into my room. She sat down on the bed to my left, leaning back on her elbows. "Whatcha doin'?" she asked. "Checking out songs online," I told her. Ashleigh grunted a reply, still holding her eyes on me. From the corner of my eye I looked at her tanned, lean legs and how her breasts rose from her chest, pushing out at her tank top. My cock was hard in seconds. I focused on the monitor's screen again, trying to ignore my sister and how sexy she was. "If you're busy, I can go. I didn't mean to interrupt you," Ashleigh said. "No, it's okay. I'm just killing time," I told her. "I thought you might want to be alone so you could look at porn or something," she said, sounding somewhat serious. "No," I snapped. "I guess you would have at least closed your door then, so no one caught you jacking-off," she said with a giggle. I turned and gave her an irritated glare. "What? It's not like you're the only one who does it, Bryan. I always make sure my door's closed when I rub-off," Ashleigh said, sounding shameless. I turned to her again, looking shocked. "Come on. Don't looked so surprised. Did you think I never did that too?" "I... I don't know. I've never thought about you like that, Ash," I said. "Yeah... right," she scoffed. "If I weren't your sister, you'd jump me right now." She let out a brassy laugh. "If I weren't your brother, you'd let me," I shot back. The smug expression faded from Ashleigh's face and she raised an eyebrow. "Touché," she said, grinning. I smiled and turned back to my computer, wondering how seriously to take my sister. I could feel the sexual tension in the air, but it was far from the first time I could when Ashleigh and I were alone. While around other people, especially our parents, we had an unspoken understanding to never do or say anything that might cause anyone to call into question the nature of our relationship, but when we were alone the conversations were often somewhat vulgar and full of innuendo. "So, are you up for more beachcombing next weekend?" she asked. "Sure, if the weather's nice," I said. "You pussy! I can't believe you found it too cold today," she jeered. "You didn't?" I countered, turning my head towards her. "Okay, so it was a bit nippily out." Ashleigh smirked, darting her eyes down to her chest. "I noticed," I replied, grinning. "You noticed more than just that when you were picking up glass beside me. I thought your eyes were going to jump down the front of my top." My sister laughed hard, making her breasts quiver. I shrugged, not bothered by her teasing. "No, it didn't look like there would have been enough room for them. It looked pretty crowded in there," I said as my eyes moved to her chest. Ashleigh let out a soft laugh that I found very sexy. Her bright eyes had a playful glint to them that they always seemed to take on as our lewd banter escalated. "I guess this top is kind of tight," she said, wiggling her shoulders a bit. "Yeah..." I was growing increasingly horny. If my sister noticed, she never acknowledged it. But she had probably assumed I was; that was her intention. These sorts of conversations with Ashleigh always made me horny and usually resulted in me masturbating once I was alone. At times I noticed her disappear into her room for a while after our ribald exchanges and I guessed that she was as turned-on as I was. Sometimes I would imagine her rubbing and fingering her wet pussy just down the hall in her room while I jerked off. "Doesn't it look good on me?" Ashleigh's voice sounded coy and insecure. "Of course it does. Everything you wear looks good on you, Ash." My sister smiled at my compliment. "But don't some things look better than others?" she prodded. "Of course." "Like...?" I thought for a moment, then smiled. "Like that white dress with the blue flowers," I said. "The sun dress?" "Yeah..." I sighed. The image of seeing my sister's cleavage and bare legs the last time she had worn that dress filled my mind. "I never wear it anymore. The last time I did, one of my boobs nearly popped out." I laughed hard, trying to imagine the scene. "I'm serious. It was last August, during Mom's birthday party, when we were out on the patio barbequing. I dropped my napkin and when I bent down to pick it up my right tit was practically hanging out. I think that dad really got an eyeful." Ashleigh let out a nervous giggle, shifting her eyes from mine. My salacious curiosity was piqued at my sister's comment. I felt my cock twitch and push out at my jeans even more. "How much did he see?" I asked, trying not to sound overly interested. Ashleigh shrugged. "I don't know. I turned around as fast as I could and pulled my dress up, but he might have seen everything. He smiled at me when I turned around again and I caught him looking over a few times after that." "It sounds like he wanted to see more." Ashleigh's eyes met mine, then a shrewd smile came over her face. "You pervert," she said with a chuckle. "I bet you'd like it if I showed Dad my tits." "Not as much as he would," I spat out. My sister laughed again. Not long after that we heard the voices of our parents downstairs. I grew nervous and my sister seemed to feel the same. It was getting close to supper time, so we decided to go downstairs and spend some time with our parents before they came looking for us. ### My first class that Monday morning was at ten. Ashleigh didn't have to be at school until one o'clock, so she said I could have the car and she'd take the bus. By the time I got home that afternoon the house was empty. Mom and Dad were at work and my sister had not gotten back from school yet. I went up to my room to check my email and look online for some information on Thoreau and Emerson for an English assignment. I enjoyed the solitude and the quiet house. After a while I grew bored and began searching through my Bookmarks for websites to visit. As was usually the case when I was in that sort of mood I ended up at a porn site. I hesitate to call it porn, but erotica, rather. The site featured pictures of beautiful young women undressed, posing provocatively, but not was blatantly lewd as on some other sites that seemed more like gynecology textbooks than erotica sites. When I saw a model who reminded me of Ashleigh my cock was at full attention. I shifted in my seat as my erection strained my jeans. I unzipped them and tugged them down, not taking my eyes off of the woman on the screen who so resembled my twin sister. Once my jeans and underwear were down around my knees my cock rose towards the ceiling, it's reddish head pointing towards me slightly. I began to stroke it, imagining the model was my sister and I was running my hands over her, groping and prodding at every inch of her. I was lost in fantasy and driven wild by lust and arousal. A bomb could have landed on the house and I don't think I would have noticed. I was too consumed with my dirty thoughts as I stroked my cock. I closed my eyes and leaned back in the chair, breathing heavy. It was only a few minutes later when I opened my eyes slightly that I noticed a form from the corner of my right eye. I froze and turned my head, still holding my rigid cock in my hand. Leaning against the doorway to my room with her arms folded and a smile on her face was Ashleigh. Her eyes were wide as they locked on my hard cock in my hand. "Don't stop because of me," she said. Her voice was soft and almost pleading. I leapt from my chair and wheeled around. Now my sister could see my ass, but that concerned me less. I struggled to pull my jeans and underwear up and stuff my hard shaft back into them. After a little struggle, and some grunting, I managed to dress myself again. Slowly, I turned around, red faced from mortification, and faced my sister. She had not moved. I could feel my still hard cock tenting my jeans. She looked down to it. "Jesus, Ash, can't I have any privacy around here?" I spat out, glaring at her. "If you're going to leave your door open, don't expect any privacy, Bryan." My sister stepped into my room and looked at the naked model on the computer screen. "Hey, she's hot. I can see why you were so worked-up," she said. I twisted my mouth, giving her an uncomfortable look. My cock was softening, but there was still a slight tent in my jeans -- enough for her to notice. I clicked the mouse and moved to my browser's Homepage. "She kind of looks like me." My sister turned and gave me a shrewd look, then smiled. I shrugged, not wanting to agree. "Well, I should leave you alone so you can... finish. Or have I killed the mood?" She laughed, glancing down to my crotch. "You killed it," I said with a faint smile. Ashleigh moved her eyes back down to the front of my jeans. Her full lips curled into a smile and she looked back up at me. "I don't know... it doesn't look completely dead. With a little encouragement I'm sure it would come back to life." I let out an embarrassed laugh. "Yeah... no... ah... it's getting kinda late anyway. Mom and dad will be home soon," I said. "I'm sorry. I had no idea that you were... that you wanted to be alone," she said, sounding genuinely regretful. "You know I always respect your privacy, like you do mine." Ashleigh seemed tentative after my outburst when she interrupted me masturbating. "I know. I'm sorry for shouting at you. I was just embarrassed, that's all. Forgive me?" I gave my sister a sheepish smile. Ashleigh slipped her arms around my waist and pulled me to her, brushing her stomach over the bulge in my jeans. "There's nothing you have to be forgiven for, and you have no reason to be embarrassed." she said, then kissed my cheek. "You've got a nice cock, Bryan," she whispered in my ear. The combination of my sister holding me to her and whispering her salty comment in my ear made my shaft begin to harden again. My hands were on Ashleigh's waist. I felt her brush over the front of my jeans again. I moved my hips slightly, avoiding pressing my crotch to her. "Thanks... I guess," I mumbled. "You guess? What? Don't you like hearing a girl tell you that?" My sister leaned away from me, giving me a surprised look. "Yeah, sure... I guess. I don't think any have, to tell you the truth. And I never thought I'd ever hear it from you." "I never thought I'd see it again. I haven't in years. You've grown a lot since then -- a lot." I let out a nervous chuckle. "So have you," I replied. "In all the right places, I hope." My sister leaned back and arched her back slightly. Her breasts pushed out at her black t-shirt, pulling the cotton tight over them. I noticed two faint nubs where her nipples had began to stiffen. "Yeah... right where it counts," I said, looking at her chest. Ashleigh smiled in appreciation and pulled me tight to her once more. When she felt my erection pressing against her she looked down. "I told you with a little encouragement it would come back to life," she said, looking back up at me. "Don't encourage me too much; Mom and Dad will be home soon," I joked. "How much is too much?" she asked, sounding serious. I shrugged. "I don't know. How much is too much for you?" My sister's expression turned serious, thoughtful. I had broken our unspoken rule of not discussing our sexual behavior. Her smile vanished. She tilted her head to one side. "I don't know. I've never really thought about it -- what's okay and not, I mean. We've never talked about it. But you've never done or said anything that I minded though. Have I? I hope not." She stared into my eyes with a concerned look. I shook my head. "No. Never. I just wonder sometimes..." "Wonder what?" she asked, squinting. "What's okay with you. I sometimes worry that I push things too far." That Which We Don't Speak Of Ashleigh shook her head. "No. I'd let you know if you did, but I don't think that will happen. Enjoy it, Bryan; I do." She kissed my cheek again and hugged me tighter. I slid my right hand up my sister's back a ways, feeling her breasts pressed to my chest as she held me. Her hair caressed the side of my face. I brushed it aside and kissed her right cheek. It was warm and soft, just like I knew the rest of her body would be. My cock was throbbing and pushing against her soft stomach. She moved, rubbing over it subtly. "I like hugging you like this when you're... excited," she said, then exhaled. "I... sometimes I wonder if you think I'm weird because that happens," I said. "No. Of course not. It's happened plenty of times when I've hugged other guys," she giggled. "It's a rush to be able to make that happen." "But they weren't your brother," I reminded her. "I'm glad. Yours is bigger than theirs felt." Ashleigh let out a sexy laugh and stole a glance down towards my crotch. She pressed on my lower back, pushing me into her. When we heard the sound of a car door closing Ashleigh went to look out of my bedroom window overlooking the back yard. "Mom's home," she said. "I'll go down. You better take a few minutes to calm down a bit," She took a last glance at the bulge in my jeans and smiled, then left my room. ### The rest of that week was uneventful. School kept me and my sister busy so we saw little of one another. When we did it was mostly during meals. It was times like that, when we were in our parents presence, that we both knew that we had to act completely proper. That meant no racy banter, teasing or leering -- although the latter was difficult for me at times. Saturday night Ashleigh came home about an hour after mom and dad had gone to bed. She had gone out with a friend to see a movie. I was watching television, after having spent the evening at a friend's house. It was close to midnight. I looked up at my sister as she entered the living room. She was wearing tight jeans and a purple blouse. My sister always looked very pretty, but there were times, like that night, when she looked especially stunning. Her hair was in a ponytail and she was wearing lipstick and eyeliner, both of which made her full lips and bright eyes look even more alluring. "How was your day?" Ashleigh dropped her purse on the coffee table and sat down beside me. She pulled her shoes off and curled up on the sofa beside me. "Not bad. I hung out at Jason's place for a while and played Guitar Hero," I said. My sister nodded. She leaned on my shoulder and pulled my right arm around her so it was resting on her stomach. As she guided my hand around her I felt my fingers rub along the underside of her right breast. It was firm and I could feel the material of her bra through her blouse. That brief contact was enough to make my cock begin to thicken and harden. "I haven't been able to spend much time with you lately. I had an assignment for my Art History course and a project for Jewelery class," she explained. "How did they go?" "Not bad," she said. "My instructor likes what I'm doing with the beach glass." "That's good." Ashleigh nodded. "You still up for going with me tomorrow to look for more?" "Sure. When?" I asked. "After noon sometime." There was a horror movie on television that looked about thirty years old. I had only been watching it to pass the time, but my attention was not on it now that my sister and I were cuddled on the couch. Her left elbow was gently resting on my right thigh, not far from the growing bulge in my jeans. I looked down, wondering if she had noticed my erection. Her thumb was slowly caressing the backs of my knuckles as she held my hand against her soft stomach. Her warm body felt wonderful against me. I wished she would allow me to run my hand over it, exploring her curves and crevices. After a few minutes of silence she sighed and shifted her hips, nuzzling closer to me. My hand slid over her stomach as she moved her arm, still holding my hand. My right bicep was pushing against her breast. It moved slightly and I eased my arm tighter around her, pushing on her firm mound harder with my arm. "Are you hard?" Ashleigh asked, sounding nervous yet curious. Ashleigh was staring at the television, eyes half-closed. When she asked her question it surprised me and made me anxious, but I saw no reason to lie, given the nature of our relationship. Sometimes that sort of openness excited me because it's normally so forbidden between siblings. "Yeah...," I admitted. "Sorry," she said in a soft voice. "For what?" My eyes widened and I looked at her. She tilted her head up to me. "I just feel bad sometimes when you get like that and can't do anything about it." Her eyes had a sympathetic look as they met mine. "I don't want you to think I'm just teasing you, or whatever." "No, Ash...I know you're not. It's okay." My sister smiled and rested her head on my chest. "I guess you could always go to your room and do what I saw you doing the other day," she said with a chuckle. I never replied. "Do you do that a lot?" she asked. "What's a lot?" I countered. "I don't know. Every day -- like me, except those times of the month when I can't. But then there's always the shower..." she said, then giggled. My heart sped up and I felt my cock twitch when I heard my sister's admission. I tried to imagine her playing with herself, which made me even more horny. "Yeah, I guess you could say I do it a lot," I admitted with a nervous laugh. "Will you tonight?" My sister was staring at the television -- probably too bashful to meet my eyes. "Ash... come on," I begged, growing uncomfortable. My sister giggled at my sudden awkwardness. "I'm going to later," she blurted out, as if she had to force the words from her mouth before she lost her nerve. I looked down, giving her a look of surprise. She smiled up at me and blushed. "Don't look so surprised, Bryan," she said. "I... I guess I shouldn't be. I'm just not used to you talking about doing it though," I said. Ashleigh shrugged and gave me a smile. "I know. But I feel like I can say anything to you and you won't mind." "Yeah... that's true." "Besides, it's your fault," she added with a nervous giggle. "Mine?" I spat out. My sister laughed at my shock. "Yeah... you touched my boob when you put your arm around me and it gave me naughty thoughts. And now your arm is rubbing against it. "Sorry. I didn't mean to touch it," I said. "I know... I guess," she said. "You guess?" I exclaimed. "It was an accident, Ash. I swear!" Ashleigh laughed at how flustered I'd become. "Okay..." she relented. "But I know that the other times your hand brushes over them when you hug me can't all be accidents." She looked up with a cynical grin. "I have no idea what you're talking about," I contended with a defiant smile. "Yeah... sure, little brother. It's okay though. I know you can't resist sneaking a feel now and again since they're so nice," she gloated, sounding uncharacteristically vain. "What was it that you meant by it giving you naughty thoughts anyway?" I asked. "Oh... I... umm... I meant because it was you who touched it -- it felt wicked... you know... naughty." "Because I'm your brother..." I concluded. Ashleigh gave me a shy nod and smiled. "Uh-huh," she grunted. "Does this feel wicked?" I reached up and brushed my fingertips along the underside of her right breast. It was firm and shifted slightly as I stroked it. "Stop that!" Ashleigh giggled and squirmed, grabbing my hand. My sister was clutching my hand firmly in hers, but in doing so she had pushed it back up to her breast. My thumb and the backs of my fingers sank into her firm mound. I felt the tip of my middle finger rub over her nipple, making it harden and swell some more. I wiggled my finger, teasing her sensitive nub until I felt it thicken. "Hey... quit rubbing my nipple... you pervert!" My sister squealed, writhing and giggling as she tried to pull my hand away. "Ssshhh... you'll wake mom and dad," I hissed in her ear. Ashleigh froze and clamped her mouth shut, still squeezing my hand against the mass of her firm breast. My left arm went around her waist as she leaned against my chest, holding her to me. I brushed my finger over her stiff nipple again. It felt thicker and longer now. When she looked up at me, sucking on her bottom lip, I noticed that her cheeks had begun to flush. "I know what you're going to go do later," she taunted. "Oh...?" "Yeah... the same thing I caught you doing on Monday," she said. "But you said you do it every day too. You're probably glad to feel a hand on your tit that isn't your own for a change," I shot back. "You prick..." she spat out, sneering a bit. Ashleigh laughed and elbowed me in the ribs, hard. I groaned. She struggled to free herself from my arms by twisting her body to the right. We hadn't wrestled for years and she was stronger and more limber now. The combination of her writhing and feeling my hands stray over her breasts excited me even more. When she turned with her back to me, trying to move to the other side of the couch, I reached out and grabbed her bra strap through her blouse. She froze, feeling me tugging at it. "Trying to rein me in like a horse, little brother?" she gasped, still struggling, but smiling. "Yeah..." I said in one breath. I was even more horny now and didn't care if she knew it. Maybe I wanted her to. "Let go," she whined, trying to pull away from me. I gave the strap of her bra a harder tug, trying to haul her back towards me. That's when I felt the hooks unfasten. She lurched forward as her bra unfastened. I was still holding the right side of her strap through her blouse. Ashleigh relaxed her body and I gently pulled her towards me by her broken strap. She leaned back against my chest. "Damn... that was one of my favourite bras," she lamented with a frown. "I'm sure you look better without it on anyway," I joked. "Seriously, Bryan -- I paid almost seventy dollars for that bra." "What?" I exclaimed, surprised by the price of womens' undergarments. "That's cheap compared to some. Don't you think my tits are worth it?" Ashleigh smiled at me. "Yes...every penny, and more. I'm sorry. I'll buy you a new one," I promised. "Okay. But you'll have to let me pick it out," she stipulated. "Why?" "Because I can see you choosing something see-through for me to wear." My sister gave me a shrewd grin. "So? It's not like I'll see it when you wear it." I countered. Ashleigh gave me an enigmatic smile. "You never know..." I tugged at the bra straps over Ashleigh's shoulders through her blouse. I stared down at her breasts as the bra cups slid up and over them. Her heavy breasts fell free with a pronounced bounce. Seconds later I noticed her firm nipples pushing out at the thin cotton of her blouse. Her bra was gathered around her upper chest, billowing out her blouse. It looked quite funny, I thought. "It looks like you have four boobs now," I said, nodding down towards her chest. My sister looked down and smiled. She arched her back, sticking her chest out. Her nipples looked thicker and longer now as they pushed out at the taut fabric of her blouse. "Which pair do you like better?" she asked, smiling. "The bottom ones. They have nipples... hard ones too." "That's 'cause you were playing with them. Pervert!" she said. "Only your right one..." "Yeah... but it got the other one excited too." Ashleigh glanced down, then gave me a nervous smile. "Are you excited, Ash?" I whispered in her ear, somewhat mocking, but very turned-on. I slowly raked the backs of my fingernails on my right hand up her spine through her blouse, then back down again. My sister writhed her shoulders and arched her back. "Stop that..." she murmured with a giggle. "Why --- do you like it too much?" I taunted. "It tickles..." she said in a soft, hoarse voice. I placed my left hand on her shoulder and eased her back until she was resting on my shoulder. "I'm sorry about your bra, but you look better without it," I whispered into her ear. "Stop trying to sweet-talk me. I'm still pissed with you about that," she said. "Was it a sexy one?" I asked. "Yeah... want to see?" "Sure," I said, surprised by her offer. Ashleigh unbuttoned the top few buttons of her blouse and pulled it open. Her bra was bunched up around her upper chest, just above the top of her cleavage. It was black, with lace on the upper cups and silky material below that. My cock throbbed as I imagined her wearing it. She shifted her hips and I felt her ass pressed against my erection. Neither of us moved. "It is sexy..." I said, still dragging my nails up and down her sensitive back. "Uh-huh..." she grunted. "It looks like you could see right through the lace," I remarked "Yeah... but the black silk covers my nipples." Ashleigh's voice was soft and thick. "Too bad," I said with a short burst of laughter. "I'll buy you another one like it," I told her. "Thanks. If you're nice, I might even model it for you," she said, turning her head to smile at me. "Really?" I was unable to hide my surprise and excitement over her offer. Ashleigh chuckled at my obvious delight. "Just a sec..." she said. My sister leaned forward and reached inside her blouse. She fumbled with the left side of her bra, pulling it down snug over her breast after a slight struggle. Once she had finished she turned and pulled the left half of her blouse away from her, smiling up at me. I stared at the black silky material stretched over her firm orb. Through the lace I could see the soft skin of her rounded breast. The black material covering her hard nipple looked like a second skin. I licked my lips, imagining sucking on it. "How's it look?" she asked, sounding anxious. "Perfect," I breathed, not taking my eyes away. "My boob or the overall effect?" she asked, fluttering her eyes. "Both," I said. Ashleigh tightened her lips and nodded. "It feels nice on them too," she said. "I can tell," I said, then smiled. "It was already like that before though... you know that." My sister leaned on my chest, wrapping her left arm around my lower back. I continued to stare at her breast, now less than a foot from my face. I put my arms around her, keeping her against me. "Can I see the other one?" I asked. "I didn't put it back in the bra." "So...?" I looked up and grinned. "One at a time, little brother. I don't want to get you too excited," she teased. "Besides, I want to get to bed." "Okay. I should too." I got up from the couch, watching my sister as she stood up. Ashleigh pulled her blouse closed and placed her hands on my shoulders. She kissed my cheek softly. "Don't stay up all night jerking off. We have to get to the beach tomorrow." She gave me a teasing laugh, then made for the stairs. ### I woke up that Sunday as our parents were getting ready for church. Ashleigh and I had not attended for years, but mom and dad were quite religious. They seldom missed church each Sunday. After that they would always go to a cafe for brunch and return home by mid-afternoon. I waited until Mom and Dad had left, then got up. As I was finishing-up in the bathroom I heard Ashleigh's door open. I had just a towel wrapped around my waist as I dried my hair after getting out of the shower. I thought she must need the bathroom so I opened the door and stuck my head out. "Did you want to get in here?" My sister was wearing a pair of light pink pajama tops that came down mid-way over her thighs. The top two buttons were undone. In the narrow slit I could see her upper chest. Her hair was messy from lying on her pillow, but I found it attractive. "Oh... sorry. I didn't know you were topless," she said with a nervous giggle. "It's okay. Do you want the bathroom?" My sister's eyes lingered on my bare torso, moving up and down my chest. She stepped closer and a faint smile appeared in her face. "I don't think I've seen you without a shirt on since we were kids," she remarked. "Well, now you have to return the favour," I shot back. Ashleigh laughed. "No; that wouldn't be fair. I've got more to see up top than you do." "Oh, really?" I grinned, eying her bust, filling out the front of her pajama top. My sister laughed, taking another two steps towards me. "Yeah... I do. Your nipples are so small too," she said, sounding somewhat surprised. "I guess," I said with a shrug. "Well, smaller than mine, but not as dark," she elaborated. "Especially when you're cold," I added, smirking. My cock throbbed at her description of her nipples. Ashleigh let out a soft laugh, seeming bashful. Her breasts moved beneath her top. I had already assumed she had no bra on since she had just gotten out of bed. My erection was swelling and beginning to push out at the towel around my waist. I pulled the towel tighter around me, hoping my sister wouldn't notice. "I guess being twins doesn't mean that everything about us is the same. My hair is darker than yours and straight," I remarked. Ashleigh nodded, then lowered her eyes to the towel around me. The corners of her mouth curled up. "I don't think that's all that's straight at the moment though," she said, checking out the growing tent in my towel. When her eyes met mine she giggled. I felt myself blush and tugged the towel tighter. I gave my sister an embarrassed grimace. "It's okay, Bryan. Don't be so bashful. This can't be the first time that's happened around me." I sighed. "It's different with just a towel around me though," I said. "Yeah... like me without a bra, only better." Ashleigh was still looking down at my growing erection as she spoke. "It's longer than your nipples," I joked. "Thicker too, I bet," she said, sounding breathy. "A little," I teased. My sister licked her lips as her eyes shifted between my face an my growing erection rising under my towel. "Is it getting thicker now?" she asked. I nodded, starting to feel less awkward and more horny. "Would you think I was sick if I said I wanted to give you a hug right now?" Ashleigh sounded as nervous as I was. Her eyes barely met mine. "No, but I don't know if that's a good idea," I said. "Do you like it when I hug you sometimes -- like on the beach when you were cold?" I nodded and smiled. "Then let me, Bryan. No one will know. Mom and dad won't be back for hours," she said. When my sister placed her hands on my waist and eased me towards her I felt myself weaken. Her touch as gentle as her hands glided up my bare back and she pulled me to her. I put my arms around her and ran my hands over her lower back. When her breasts pressed against my chest I almost moaned. With only the thin cotton of her pajama top between us I could feel her hard nipples poking out at me. They felt as hard as the beach glass we had gathered the week before and thick. Her breasts moved when she shifted her shoulders, rubbing over my chest. When I felt my hard cock pushing against her stomach I eased away from her, but she pulled me back until my erection was firmly against her. "Are we perverts?" Ashleigh sounded worried as she whispered into my ear. "Most people would say that if they saw us now," I said. "What do you think though?" she asked. "I don't care what they think. I love you, Ash." "I love you too," she gushed, clutching me tighter. Ashleigh held me tight and moved her hips a little. The sensation of my hard shaft rubbing over her felt wonderful. I held her body against mine, resting my chin on her shoulder, and sighed. Her fingertips ran up and down my spine, adding to the wonderful sensations I was already feeling. She began to sway her hips, grinding herself against my hard cock. I looked down between us and saw some of her cleavage in the opening of her pajama top. Her breasts were pushed up a bit as she hugged me, enough to allow me to see their rounded shape. She smiled when she noticed me looking. That Which We Don't Speak Of "If we keep doing this, will... will you... get off?" she asked, breathing over my chest. "Yes," I sighed. "Do you want to stop then, or..." "Do you?" I asked. "No." My sister hugged me tight and moved her slender hips a little faster, massaging my erection with her stomach. "What about you though?" I asked. "I'm okay. It's alright," she said. "That's not fair, Ash. You should enjoy it too." "I am -- believe me," she said. sounding quite horny. "You know what I mean," I said. I pulled the bottom of the towel up my leg and slipped my right thigh between my sister's. Her skin was soft against mine as I pressed my thigh against her mound. The heat of her pussy radiated through her panties and they felt damp on my skin. I began rubbing my thigh over her soft lips and pressing harder on her clit. She moaned and clutched my shoulders, digging her nails in me a bit. "Mmmm... you're being really naughty, little brother," she moaned. "Do You like it?" I asked. Ashleigh's reply was another moan as she leaned against my chest, still moving her hips and humping my leg. Soon she began thrusting her hips, rubbing over my thigh faster. I pushed back, feeling my shaft pushing against her stomach. "God... you're practically fucking me, Bryan..." she moaned, gripping me tighter. My sister's words excited me and fueled my lust. I slid my hands down and held her by her hips and began moving her over my bare thigh faster, shoving my cock against her harder as I moaned. Her juice was making my leg wet so she slid over me easier now. "I'm so wet," she sighed. "Can you feel it?" "Yes," I said, breathing the word. Ashleigh reached down and pulled the hem of her pajama top up, then tugged her panties aside to uncover her pussy. When she pressed it to my bare leg we both moaned. Her lips were very wet and soft. She wrapped her arms around my neck and held on to me. I looked down between us, but her pajama top had fallen down again to cover her. "Did you jerk off last night?" she asked, breathing over my cheek and neck. "Yeah..." I grunted. "I did it too... my panties were soaked when I took them off." When I slid my hands under my sister's pajama top and ran them over her bare hips she never resisted. I squeezed them, working her pussy over my wet thigh as she moaned and bathed me in her hot breath. When she came a little for the first time she let out a louder moan and pressed herself to my leg harder. "Keep going," she coaxed, grinding her soaking pussy against my leg. I slid my right hand around to her ass, grabbing a handful and pulling her to me. Her ass was firm and smooth. My fingers slipped beneath her panties and I gave it a harder squeeze. Ashleigh whimpered into my ear and nuzzled against my neck. When my sister arched her back and let out a loud, sexy moan I knew she was cumming again. Hearing and watching her in so much ecstasy was all I needed to climax too. I let out a loud groan as my body stiffened. I felt my cock twitch as I sprayed cum over the inside of the towel. "Oh god... I love you, Ash," I moaned, holding her body against mine. Ashleigh murmured a reply. I felt a small gush of her juice run down my leg as she writhed in my arms. She bit my shoulder, moaning as she came. Only when I felt her trembling body relax did I ease my grip on my sister. I leaned away from her and pushed her hair back from her face. I kissed her forehead and smiled. "I love you, little brother," she said in a shaky voice. I kissed her pink cheek. "I love you too, Ash," I said. My sister slid off of my leg and adjusted her pajama top, seeming shy. She pulled her hair back over her shoulders and looked down at the towel around me. There was still a noticeable tent in it. She smiled. "Do you want to wash up some before I use the bathroom?" she asked. I shook my head. "No, I'll just use the towel." As I began to recover from cumming so hard I grew somewhat shy at the thought of what had actually happened between me and my sister. I gave her a sheepish smile. She seemed nervous and awkward too. "So... do you still want to go to the beach later?" she asked. I nodded. "Yeah... after I get something to eat," I replied. "Cool. I want to have a shower and get dressed, then grab something to eat," she said, fumbling nervously with the hem of her pajama top. I closed the bathroom door as I left. I went to my room to wipe my cum and my sister's juice from my leg and get dressed. I was finishing my second bowl of cereal when Ashleigh joined me in the kitchen later. Her hair was still slightly damp from her shower. It looked attractive, falling over her back and shoulders. She was wearing a white, knee-length skirt with a blue batik pattern that reminded me of pictures of Tibetan mandalas I had seen. She also wore a beige tank top and sneakers. Her top had a square neckline and spaghetti straps that left her shoulders and upper chest bare. It was obvious that she was braless. Not simply because her top would not hide a bra straps, but because of how her breasts looked and moved freely beneath her top. I smiled as I watched them bounce as she moved. "I just want to have a bagel and some juice, then we can go to the beach," she said. "Take your time. We have all afternoon," I said. Ashleigh looked out of the kitchen window, frowning. The sky was covered with low, dark grey clouds. I had noticed them earlier and worried that it might rain. Now she seemed to have the same concern. "I hope it doesn't rain," Ashleigh said. "Me too. But we can stay until it starts, if it does." I had been apprehensive about facing Ashleigh after I got dressed. Given the significant boundary we had crossed earlier in the bathroom I wasn't sure about what the status quo was anymore. She surprised me by behaving no differently than usual, as if it had been someone else I had just practically had sex with earlier. I was filled with an odd mixture of relief and puzzlement; I was also somewhat dismayed. It wasn't as though my sister was aloof or cold -- just seemingly unaffected by our encounter. I had expected her to behave differently after what was for me the best sexual experience of my life. I finished eating while my sister sat across from me, munching on her bagel. She ate quickly, then handed me a plastic bag, which I tucked in the pocket of my jeans. We headed out to our car for Watkins Beach. ### It was windy along Jackson Road as Ashleigh drove towards the beach. She had the radio turned up and seemed cheerful, which I found reassuring. The dark clouds had not dissipated, but at least it had not started to rain either. For that much, I was grateful. It was humid and I was looking forward to the breeze off of the bay for once. Ashleigh drove down the narrow, tree-lined road towards the beach. Branches of pine and spruce trees rubbed along the sides of the car as she navigated the muddy path. She parked the car in a clearing amongst a thicket of alders and pine. We climbed down the sandy embankment towards the rocky, windswept beach. "Let's go over this way this time," my sister said, pointing to her left. I followed Ashleigh, watching her hair and skirt being blown about by the wind. Her nipples also had reacted to the breeze, swelling and stiffening to push out at her thin top. I smiled and quickened my pace to walk beside her. She turned and smiled, but said nothing. I knew what she meant and I gave her a wide smile. She chuckled and turned towards the water's edge. Ashleigh and I began searching between rocks and kicking aside kelp and Irish moss, searching for pieces of glass. "I found some," she said, squatting to pick some glass from the sand. I pulled the plastic bag from the pocket of my jeans and held it open for her to deposit the glass in. I crouched down beside her and joined her in the search. After about a half hour my sister and I had found almost a handful of glass. She was very happy. We turned and made our way up the beach in the other direction. The tide had gone out recently and the rocks were still wet. She reached out for my hand to steady her. I took hold of it and we walked along hand in hand. Now we genuinely felt like lovers to me. "This is where we found some last week. Let's see if there's more," she said, tugging me towards a patch of gravelly sand. My sister bent down, scanning the beach for glass. I walked ahead of her by thirty feet or so, doing the same. We had walked about a half mile from where we had descended the bank to the beach. Occasionally Ashleigh or I would stop when we saw bits of glass in the sand. She hurried to catch up with me. I turned, watching her heavy breasts jiggle, and smiled. Ashleigh was out of breath when she reached me. She dropped a small handful of glass in the bag and smiled when she noticed me looking at her hard nipples. "I can't wear a bra with this top; the straps are too thin," she said. "I saw where your eyes were, Bryan." She giggled and held my hand, pulling me against her right side. We continued along the beach, not letting go of one another's hand. It was like all time had ceased and this was a world created just for us. When my sister saw some glass she tugged me along towards it, only releasing my hand long enough to bend down and pick the glass up. When I felt the first few raindrops land on my face I wasn't sure if I was imagining them or not. Seconds later it began to sprinkle. "We better get back to the car," I said. Ashleigh and I turned and began walking back in the direction from which we had come. When the light shower turned into heavy rain my sister tugged at my hand and began to run. "Come on, Bryan. Let's go!" she called out. I gave a slow tug at her hand. "No, these rocks are too wet. If we slip on them and fall we'll split our heads open," I warned her. Unhappy with my caution, but realizing I was right, my sister settled for navigating the smooth rocks as quickly and deftly as possible, using me to steady her. It was pouring now. My t-shirt and hair were getting soaked. So were my sister's -- although she looked much better wet than me. Accepting that you can only get so wet and that it was inevitable, Ashleigh and I resigned ourselves to cautiously getting back to the car safely rather than dry. We dashed up the wet, sandy bank towards our car. Rain was bouncing off of the roof of it and running down the windshield. We jumped inside, slamming the doors shut, then sighed. "I'm soaked," she said, frowning. Once I had caught my breath I looked over at my sister sitting beside me. Her drenched hair hung down around her, far wetter than it had been earlier in the kitchen. Her wet t-shirt clung to her, making the size and shape of her breasts and hard nipples very noticeable. I stared as I smiled. "I'm not going anywhere until this lets up. It's not safe to drive," she said. "I can't even see out the windshield." I mumbled a reply, preoccupied with her clinging tank top. She turned towards me and smiled when she noticed me ogling her. "Well, at least you have something to look at while we wait," she giggled. "Yeah..." I said, still smiling. Ashleigh wrapped her arms around herself, giving me an apologetic look. "Sorry to spoil your view, but I'm cold," she said. "Come here," I offered, extending my arms. Ashleigh slid over and leaned on my chest. I put my arms around her wet body and held her tight against me. My cock had been hard for some time already. Holding her and looking down at her wet tank top fed my arousal. I ran my hand up and down her back, trying to warm her. She looked pale and was shivering a little. "I bet you're sorry I'm not wearing a white t-shirt now," she remarked with a smirk. "This top looks pretty good right about now though," I said. Ashleigh gave me a flirtatious look, still smiling "Yeah, but remember how I said that my nipples are darker than yours..." "How much darker?" I prodded. Ashleigh pulled her top away from her chest. She peered down inside it, darting her eyes left and right with a smirk. "A bit right now, since they're excited," she said, looking back up to me. My sister's finger was still hooked in the neckline of her top, tugging it away from her chest. I reached out to it and gave it a slow tug with my finger, waiting for her to react. She smiled as I pulled it lower over her upper chest. My left arm was around her waist, holding her to me. I craned my head, attempting to peek down her top. She giggled, sounding quite sexy. "Want a better look than that, little brother?" she cooed. The rain was still beating down on the car and running down the windshield and windows. They were beginning to fog and I couldn't see out of them. I smiled at my sister and nodded. "Yeah... can I see?" I asked, perhaps begged. Without a word my sister tugged her top off, giving her tangled hair a shake to free it from the straps. Her breasts swayed and shook as she moved. I ran my eyes over them, licking my lips as I stared at her chestnut-colored nipples and the slightly lighter rings surrounding them. Ashleigh ran her hands over her damp breasts and cupped them so her thick nipples pointed towards me. She was so close that they almost grazed my chest. "God, Ash... they look nice," I gasped, as I admired her full breasts, overflowing from her hands. My sister gave me a pleased smile and brushed her thumbs over her hard nipples. She bent down and swirled her tongue around her left one, looking up to see my reaction. "I love being able to do that," she said and smiled, licking her lips. "So do I..." I grinned. Ashleigh giggled. "But I never said you could, little brother," she taunted, still holding her heavy orbs in her hands. When I drug my fingernails up her bare back Ashleigh closed her eyes and squirmed a bit. She leaned forward so her breasts rubbed over my chest. "No fair... you know that gets me going," she moaned. "What else gets you going, Ash?" I asked, still running my nails up and down her tender spine. "Letting my brother hump me in the bathroom and showing him my tits." Ashleigh's voice was soft and sexy. "You're twice as sexy when you're horny," I told her. "Like now..." She opened her eyes and gave me a wanton smile. I pulled her to me. Her breasts pressed against my chest and her damp hair brushed the side of my face. I pushed it aside and kissed her damp cheek. "Want to borrow my leg for a little while?" I asked, my lips brushing over her soft neck. "Do you feel like doing it?" she asked sounding nervous. I took her hand and placed it on the bulge in my jeans, pressing down on it so she could feel my erection. "Yes, I do," I said. "Oh my... Bryan..." she gasped as she began rubbing my hard cock through my jeans. I began tugging at Ashleigh's skirt, bringing it up her thighs. She was fondling my balls when I saw her panties come into view. They were pink bikini cut. I could see the outline of her lips and a damp spot where the material covered her mound. She gave me a nervous look when she saw where my eyes were. I quickly unfastened my jeans and tugged them down past my knees. My underwear did little to hide my hard shaft. It tented them out, making a wet spot of pre-cum on them. Ashleigh looked down at the outline of my cock, covered by the stretchy cotton. Once I had pushed my jeans down towards my calves I put my hands on my sister's hips, guiding her to straddle my bare thigh. She raised up on her knees, bracing her hands on my shoulders. I tugged her skirt up towards her waist so it would not get between us. Her breasts were in my face and I leaned over a bit and ran my tongue over her right nipple. "Hey..." Ashleigh exclaimed with a giggle. "Does that get you going too?" I asked. She nodded. Still holding my sister by her slender hips I wrapped my wet lips around her left nipple and began to suck and tug at it with my lips. She gripped my shoulders tighter. I moved my mouth over to her right one, sucking and pinching it between my lips. When Ashley lowered herself onto me I felt my shaft press against her pussy. Only our underwear separated us. She gasped in surprise and lifted up. I smiled at her. "Didn't you like that?" I asked. "I... yeah... I just wasn't sure if... if it was okay..." she stammered. "It's better than okay." I rubbed my hard cock through my underwear a bit while my sister watched. When I pulled them down towards my jeans and my erection began rising towards the roof of the car her eyes grew wide and her mouth fell open. "WOW... Bryan..." was all she said. "You've seen it once before," I reminded her. "But your hand was covering it and I wasn't this close." I guided my sister back down to my thigh. I gathered her skirt around her waist and pushed it aside. Now I could see her damp panties clearly. When she pressed herself to my thigh and I began moving her over it she let out a quiet moan. The heat and dampness of her pussy radiated through her panties on my leg. The underside and head of my cock rubbed against her as she slid up my leg. She had one hand on the car seat and the other on my shoulder. I squeezed her firm ass, grinding her pussy against me harder. "Mmmmm... that feels so good, little brother," she moaned. I grunted and nodded, watching her breasts quiver. I sucked a nipple into my mouth again, opening wide to wrap my lips around her areola too. She gasped and let out another soft cry. "Want to pull them aside, like last time?" I asked. "Huh?" My sister looked at me with a confused look. "These..." I said, tugging at the waistband of her panties. Ashleigh thought for a moment, then the corners of her mouth curled up and her eyes flicked. "No...just a second," she said. She slid back on the seat and pulled her panties off completely, then tossed them behind her. "That's better," she said. I smiled, looking at the sparse, triangular patch of hair, one shade darker than that on her head. Her pink lips were shiny and wet. I looked down at them as she lowered herself back onto my leg. I held her by the hips and slid her higher on my thigh. Her musky juice wet my skin and helped her to move. "This feels so good, Bryan," she said. Ashleigh moved her hips and leaned forward to grind her clit on my leg. Her hair and breasts hung down towards my chest and moved in rhythm to her sexy body. The head of my cock brushed over her bush, just inches above her dripping pussy. The sensation was nice, so was the thought of knowing I was so close to being inside my twin sister. I began to slowly stroke my cock, rubbing the head against her hair and soft thigh occasionally. Ashleigh had begun sliding down towards my knee, so I gave her ass a squeeze, pulling her closer. When she lifted up to reposition herself I saw her soft, wet petals. I held her tighter, keeping her wet pussy above my leg and pulled her towards me. When she felt the head of my cock slide over her wet lips and rub on her clit she moaned and looked down. She gave me a look of shock, then a lusty smile. I held the base of my cock and slapped the head against her swollen, pink clit. She gave a sharp inhale and a soft moan. "Going to spank my naughty pussy, little brother?" she goaded in a husky voice. My reply was to slap my shaft against her sensitive button two more times, making her gasp and moan. She moved her hips and I rubbed the head over her wet lips. They were silky soft and parted slightly as the swollen head pushed between them. My sister's eyes widened as she looked down at my cock pressed to her wet folds. "More..." she moaned, looking int my eyes. "What?" I asked. "I want to feel more of it in me, Bryan... push it in... don't tease me. I'm so horny." "Are you sure, Ash? We can just keep doing what we did before." That Which We Don't Speak Of My sister shook her head. "We've been teasing ourselves and each-other for too long, Bryan. This is what's natural for us -- even if it isn't for other people." Ashleigh reached down and curled her soft hand around my rod. She gave it a squeeze as she guided the head inside her. As my shaft filled her she let out a soft cry of pleasure, lowering herself onto me. She gripped the car seat and my shoulder harder and began to glide up and down on my cock slowly. I held my sister's hips, helping her to fuck my hard cock. Her breasts began to shake as he moved faster, riding me hard. Her jaw was tight and she was looking down, watching me move in and out of her tight pussy. "God... little brother... shit, your cock feels so good," she groaned. My hands were holding my sister's ass while she moved up and down. I grabbed handfuls of her cheeks and helped her work her wet pussy on my cock. Her juice ran down my shaft onto me as she squeezed my cock tight deep within her. "Let me know before you cum," she said in a series of gasps. I nodded and grunted, still helping her to ride my shaft. My hand slid around to her front, down to her clit. I pressed my thumb to it and rubbed. She moaned and squeezed my meat harder. When she came for the first time I felt her juice running down to my balls. I rubbed her button faster. "I'm... oh god... fuck me hard, little brother," she cried out above the sound of the rain beating on the car. When I knew that I could not hold out any longer I reluctantly moved my sister off of my cock. I wrapped my hand around it and stroked, sending a blast of cum over her stomach and thigh. She wiped it up and licked her fingers, just as two smaller ropes splashed over my thigh. I collapsed against the car door, trying to catch my breath. Ashleigh was rubbing her clit and licking cum from my leg. She had one final orgasm, crying out so loudly that I worried people down the road might hear. My sister and I lay together, satisfied and covered with one another's juices. Ashleigh rested her head on my chest. It was quiet now. The rain had stopped -- as though mother nature was as spent as we were. "Storm's over," she said. "For now," I said. Ashleigh picked up her panties and t-shirt and put them back on. I tugged my underwear and jeans back up, then opened the car window. I was surprised to see that the sky was blue once again. My sister opened her window and turned on the fan to clear he windshield of condensation. We held one another, looking out over the bay. Ashleigh leaned on my chest, running her hand up and down my thigh. After a few minutes she sat up and pointed. "Look," she exclaimed. "A rainbow."
