TITLE: My Sister Skye PART: 1 of 3 - Oral Lessons AUTHOR: Big Al KEYWORDS: MFF cons oral fellatio cunnilingus size inc SUMMARY: Al's sister is his best friend. So naturally she comes to him when she wants some pointers about sex. ********** "Ha!" "Oh shit!" "In your face!" "Die!" My sister and I hurled expletives in rapid-fire sequence at our two widescreen TVs, as our fingers flew over our respective keyboards. We were two-manning a 4-player dungeon in the Star Wars MMO - each with our own computer hooked into a separate widescreen - and cussing up a storm as we rampaged through mobs of virtual enemies. We were both on the couch, Skye leaning back against me between my legs. Although you might think this would lead to issues with us both being able to play simultaneously with keyboards and mouses, I'm nearly 6 and a half feet tall, whereas she is only 5 foot 8. We have a setup on little sliding tables with folding arms that make it easy for us to play in this position. This is good, because my sister and I are both highly affectionate people. We're always cuddling, be it with each other or our girlfriends. Yes, I said girlfriends, as in, Skye has them too. She's lesbian (although she claims she's bi, but she's only ever dated girls). Although she's 6 years younger than me - 18 today, to my 24 - we've always been best friends, and inseparable, doing everything together. She loves almost everything I do. Including kicking virtual butt on the Star Wars MMO we play together. The door to my apartment clicked open as Donna - my current girlfriend - came in. "Hey babe!" I called, smacking my lips in the air towards her. "Hey sexy!" Skye said on the heels of my greeting. She took a moment to ogle Donna, and I nudged her back to the game before she let an enemy half-kill her character onscreen. Remember what I said about Skye loving everything I do? That includes the same kind of female bodies. Donna is slender-hipped with a massive rack, boobs as big as basketballs, yet perky as can be. She has an angelic face and long blonde ringlets that fall to her bubble butt. Donna came over and kissed me briefly, and said, "Hey babe. Hey Skye. Babe, I'm horny as hell, let's go fuck." My cock twitched in my jeans, wresting a surprised yip from Skye as she felt it. "Don't distract me, Al!" she teased me indignantly. "After we do this dungeon," I promised Donna. "Ugh, I can't wait, I'm ready to hump the arm of this couch," my girlfriend complained. "Sorry, babe," I said apologetically, "but you know Skye always comes first." I always tell my girlfriends up front that my little sister takes precedence over everything. "You know I only get to see her on weekends." Skye still lives with our parents in their big house in the suburbs, and spends weekends in the guest room of my apartment. She's planning to move in full-time once she graduates high school in a few months, and attend university a few blocks away. "Especially today," I add, trying to split my attention between the horde of enemies on the screen and my sexy, pouting girlfriend, "since it's Skye's 18th birthday." "Fine," Donna twisted her lip and sat on the couch next to me, leaning into my side. She fidgeted for a few minutes, watching the screen as Skye and defeated the second-to-last boss of the dungeon. Finally, she couldn't wait any longer, though, and reached into my pants - only able to now because Skye was leaning forward to concentrate on the screen - and fished out my cock. I gasped in surprise and pleasure as her hands deftly moved over my fat shlong. Even flaccid it was just an inch or two shy of a foot in length, and was nearly as thick as her forearm. "Donna--" I groaned, and beneath her ministrations my cock ballooned into its full size, topping out at a full foot and a half long, with the girth of a coke can. Donna leaned over and plugged up her mouth with my bulbous cockknob, sucking lewdly as she milked my shaft eagerly with her hands. "Dammit, Donna," Skye said as my concentration faltered and my character's health started plummeting. That jolted me to attention, and I managed to drop the two nearest enemies, but my concentration was lapsing again as Donna plunged down further on my mammoth cock, her drool slithering down my thick meaty pole in obscene rivulets. I was groaning like a wild beast, and it wasn't long before my character died. Shortly thereafter Skye's character died too, unable to keep up on her own, and she pushed away the sliding table - on which the keyboards rested - in disgust. She turned around, opening her mouth to give Donna a piece of her mind, then stopped as she espied my giant cock. "Holy shit!" she exclaimed. "I didn't know you were packing that much, bro!" "You've seen it," I managed to grunt out, forcing Donna's head further down with my hand atop her head, as the blonde moaned lewdly, her body quivering in submissive pleasure. It was true; we caught glimpses of each other naked all the time; it was no big deal. "And felt it when sitting on your lap," she quipped, "but I've never seen it that big." "Guys get bigger when they're hard," I managed to say as Donna bobbed her head up and down on my pole with lewd squelches and gulps. "Didn't they teach you that in sex ed?" "I wasn't paying much attention," she rolled her eyes. "You know I'm mostly interested in chicks." "Right...sorry, I'll hurry up," I promised her, and then began bucking my hips up into Donna's welcoming throat as I pushed her head down on my cock, deforming her throat with relentless slams as I face-fucked her brutally. The blonde was humming with bliss, loving the dominant treatment, and with a roar I spunked inside her. Her throat gurgled down my geysers of cum nastily as she creamed, getting off on feeling me nut in her. Skye watched in fascination. She'd heard me and my girlfriends fucking before - and often masturbated to it - but never seen it. She was hypnotized both by my mango-sized nuts clenching and releasing, and by Donna's bare pussy beneath her skirt, which was practically gushing femcum down her thighs. When I finished, Donna pulled off me, smacking her lips in satisfaction, grinning dreamily, her eyes still unfocused with pleasure. "Well, before we get back to gaming," Skye said, "I - I was wondering something. Do you think...could you teach me how to eat pussy, Al? I want to be ready for tonight." I was gonna take Skye bar hopping tonight so we could pick up some chicks and get her laid. I grinned at her and ruffled her dark brown hair - same shade as mine - and said, "You'll do fine, sis. Just act naturally. But I can give you some pointers if you like." Donna agreeably sat back on the couch and spread her legs wide, lifting up her skirt so we could have a better view of it. Her pussy was shaven smooth, just the way I like, and her pink petals were parted. Skye and I knelt on the floor before her, inhaling her fragrant 19 year old arousal. "You'll probably be better at it than I," I stuck my tongue out at my little sister. "After all, you're a girl yourself." I leaned in and started kissing Donna's cunt lightly, graduating to laps and licks and nuzzles. "Maybe," Skye said, "but I don't have stubble like you do." She had a point; Donna was gasping and purring hotly as my bristled cheek scraped erotically over her nethers. I paused every few moments to indicate something before returning to licking that juicy muff, then I pulled away to let Skye have her turn. Skye was a bit shy, but was eager to taste that sopping twat, and buried her face in it. She was a bit clumsy at first, with Donna giggling at the sensations that were more ticklish than erotic, but soon my girlfriend was moaning again. Skye came up with her face gleaming wetly. "Yum!" she said. I laughed and ruffled her hair again. My little sister and I took turns eating Donna out for several minutes, until Donna came, squeezing her legs around my head and gushing her warm fuckhoney all over my face for over a minute of intense climax. When she released me, I grinned at Skye. "You're a natural. Isn't she, babe?" "Mmhmm," Donna murmured, her head still fogged with pleasure. "Al..." Skye hesitated, "Donna... do you think you two could teach me how to suck cock?" THAT got our attention. Donna jolted to awareness as I looked at her in shock. "Since when are you interested in cock?" I asked her incredulously. Skye made a face. "I've always been interested in cock, dope," she retorted. "You've only ever dated girls," I pointed out. "Yeah, cuz there aren't any guys I like," she said. "I mean, you do set a pretty high bar, bro." I blinked; I hadn't realized Skye was measuring guys she met with me as a yardstick, but I supposed it made a certain amount of sense. "But I want cock, dammit. Dildos aren't enough. So...please, teach me?" "Oh hell to the yes!" Donna agreed enthusiastically, getting up and pushing me back down onto the couch. She obviously didn't care that I hadn't agreed yet, she was gung-ho to see my little sister sucking me off. "Fine," I chuckled. "If it'll make you happy." "Well isn't the point to make YOU happy?" Skye giggled, and I agreed with a laugh. "But yes," she added, "this will make me happy. VERY happy." "Okay," Donna said, "first you start off stroking him with your hands, get him firmed up. Be gentle now. Come on, there's enough for both of us." She was right; despite both of her hands already stroking my semi-hard shaft, there was lots of cockmeat left for Skye, and my sister joined in, rubbing my humongous dick tenderly and experimentally. I groaned in bliss; I'd had double blowjobs before (even triple), but somehow getting one that included my little sister - my best friend and the person I loved most in the world - made it incredibly special. Under Donna's direction, Skye joined my girlfriend in licking kittenishly all over my fuckpole as it reared up to full erection from between my thighs again, and pressing soft affectionate kisses to it. She met my eyes often, as to if to check that she was doing okay, and I kept smiling at her, equal parts love and lust in my gaze. She giggled as she tasted my pre, which was flowing liberally down my shaft at this point, and staining her hand in my sticky fluids. Donna opened her mouth and enclosed my cockhead between her lips, suckling like it was a popsicle, then pulled back and urged Skye to do the same. I almost came undone as I felt her hot, tight virgin mouth envelop me between her cheeks, groaning bestially as my cock lurched, ripping the head back out of her mouth. A long lewd string of drool still connected my knob to her plush lips, and Donna helped her hold my thrashing beast steady as she sucked me into her mouth again. My obese cockhead bulged out her cute cheeks, as she suckled with a will, lustily gargling my pre down her throat. "Push down," Donna urged her, fondling my balls and licking along the lower part of my monstrous dick. Skye obeyed, and I rested my hands on both their heads. They both moaned instinctively at the touch, Skye evidently loving both my meaty taste and dominant hand. She plunged down, swallowing my immense tool deep inside her throat - with my hand helping by pushing down, while she moaned nonstop - and I growled with bliss. Despite Skye's inexperience at this, the fact that it was SKYE doing it somehow made it the best blowjob I'd ever gotten. Her drool was flowing lasciviously down my huge, throbbing, veiny dick till it gleamed in the light, and at Donna's urging, she began bobbing her head up and down, lustily fucking her own throat on my immense beast of a cock. With each bob, she plunged down a little farther - again, aided by my hand - until she had swallowed my entire tremendous length. Her cute little neck was bulged out obscenely, visibly pulsing with every throb of my cock, and her nostrils flared as they inhaled the musk of my dark pubic curls. I couldn't hold back any longer and roared in triumphant rapture as I busted my nut, blowing my load inside my own little sister's mouth. Skye's whole body convulsed with ecstasy as she felt it, her panties soaking through as my massive dick lurched inside her and burst a firehose of piping-hot, porridge-thick jizz inside her, over and over. It felt like forever that I was yelling and pumping my load into my climaxing little sister's 18 year old throatcunt, but eventually we did both settle. Her throat glucked fondly around my cockmeat for several more long moments before she pulled off, my knob springing free of her mouth with a 'GLUH!' of trapped air. Long strands of drool and cum linked my whole cock with her lips as she grinned at me, her expression dreamy and rapturous and proud. "Did I do good, big brother?" she asked, then teasingly made her voice outrageously cute and innocent. "Was I a good little sister?" I chuckled and ruffled her hair again fondly. "Best sister ever," I said, and she beamed. "Damn, girl," Donna finally remembered to breathe, amazed by it. "You're fucking hot." She enfolded Skye in a kiss, and my girlfriend and my little sister swapped my cum between each other as they made out, which was enough to get my cock back to full steely hardness again. Skye finally pulled away - her nipples obviously hard pebbles through her t-shirt - and said, "I need to shower and get ready for tonight. I think you have to take care of him for now, Donna." Donna giggled and agreed, and as Skye pulled off her shirt on the way to the bathroom, Donna climbed astride my lap and mounted my cock, sinking her sloppy wet cunt down on my enormous package... ********** COMMENTS: Like many authors, I love hearing positive feedback and suggestions!
