Auntie’s amorous animal teaches the twins

The sounds of dogs yelping coming from the direction of the front lawn made the cute little freckle-faced twins run to the front window of the house. Being bigger and stronger than the average thirteen year old boy, Jacob got there slightly ahead of his smaller sister Megan. She squished in front of him though, just the same, pressing the cheek of pretty little red-head’s face, and her small, lemon shaped tits against the cool glass, as both naughty teenagers, bumped their ginger-haired heads against the big window’s pane, and gazed excitedly out onto the lawn, to see what all the commotion was about. “Awe shit!” Jacob exclaimed, “Old Lucky is going at another bitch!” “Hey, I got eye’s don’t I?” Megan laughed, as she took in the bawdy view of their Aunty Linda’s scruffy old golden Labrador, Lucky and an unfamiliar female dog, humping around out on the sunny, green grass in the front yard. Obviously he had baled up yet another stray bitch dog that had been wandering the neighborhood in heat. He had already mounted the willing female mongrel after a scant few sniffs of her juicy little tail, and had already decided to hump his pent up puppy batter, into her clenching animal womb. He was currently snapping his hairy hips at her rear like a jackhammer, as the children watched on in awed curiosity. “Fuck! Megan giggled, ” the horny old bastard!.. how many times does this make?.. three?” Megan speculated as she tried to remember the number of times she’d seen their Aunt’s pet dog fucking, during the twins stay over at her place this summer break. “Hmmmm.. Yeah I guess he must get pretty horny in-between times.” Jacob replied, a little dreamily, suddenly feeling a very nasty little thrill of horniness tickling across his crinkly, quickly tightening scrotum, and then charging up to the head of his rapidly stiffening young prick. The children where both amazed how hard Aunty Linda’s dog was fucking the horny little female dog in front of them. They could make out the hard, scarlet shaft of his wildly flexing doggy-cock, bucking and plungering into the quivering little bitch as he slowly managed to drive his nasty ripe rooter into her incredibly tight little fuck hole while she yelped in a paroxysm of pleasure and pain.. “Wow.. He can really sex her hard with his little red rocket when he wants to eh bro?” Megan said in a throaty, lust thickened voice. The sight of the two animals going at it right before her, wide blue eyes, was really turning her on she realized. I wish I knew what it was like to have a horny boy fucking me like that! Megan decided, as she watched the torrid action. She’d only started talking to other little girls her own age at school about such naughty things like sex and fucking boys just recently. Still. She had already heard enough to make her wonder just how good being fucked by a really horny boy would make her feel. She could feel tingles sparking in her little, creamy cunny, and tickling the quickly stiffening chest nubs of her immature little tits. She couldn’t help but empathize with the female dog beneath old Lucky, as she imagined herself on hands and knees below him. His cock pounding his new little bitch relentlessly with his pumping prodder, right before her lust glazed eyes. Meanwhile. Her brother Jacob was also getting pretty horny as he pressed in behind Megan’s little round rump, pressing her little body in turn flatter against the window pane as he ogled, lust-struck, over her curvy shoulder at the blistering strokes of Lucky’s fur-flying fuck frenzy. He had only started to feel a strong urge for sex and started wanking himself off just recently, but as he watched Lucky fucking the happy little female dog wiggling around and squealing whilst she squealed all the while, he was more than able to imagine how good it must feel to fuck a nice, hot, juicy little pussy for himself. “What are you doing that for?” asked his sister, suddenly making Jacob’s senses return from a lust fogged reverie. “What do you mean?” he asked, not realizing that he was playing with himself. “Why are you rubbing the front of your pants?” Megan asked innocently, full of curiosity all of a sudden.. “Because I’ve got a hard-on,” he told her. “Like Lucky has?” “Yeah,” Jacob said with a grin, lustily rubbing his erection through his pants. “Can I see it?” his sister asked. “Of course not,” he answered, getting more and more excited as he watched his Aunty Linda’s dog fucking his big, red-hot cock into his new bitches, hot, juicy hole. Megan was just as excited as her brother at that moment. The sight of Lucky’s big, juice-smeared doggy-cock hammering away at a female’s pussy, had made her all hot and itchy between her legs. She couldn’t help but wonder how it would feel to have his big prick zipping in and out , throbbing away inside of her own wet, little cunt. His cock looked awfully gross and slimy, and pretty big as well, but from the way the female dog was acting, it sure must feel good, she imagined. Staring at the horny dogs fucking, thinking about hot tight cunt, Jacob could feel his own hard boner throbbing in his pants as well. The girl dog was obviously out her mind from the intense pleasure she was feeling, she was passionately slamming her hairy haunches back, trying to force more and more of Lucky’s big dog-cock into her fiery cunt. She panted and yelped, passionately rotating her hindquarters, her hot little dog-cunt, around the steaming length of Lucky’s plunging prick. Watching and listening to the horny dogs, both kids individually decided that a good hard fucking must be the most wonderful thing in the whole wide world. Little Megan was getting hotter and wetter in her pussy as she watched, Aunt Linda’s lab slammed his dog-balls against the females furry butt, trying to get even more of his big, thrusting prick into her steamy canine cunt. The twins’ eyes almost bugged out of their heads as they saw the female’s slippery juices spurting out around Lucky’s thick, plunging cock. Frantically increasing the tempo of his strokes, Lucky was feeling a glorious buzzing sensation deep in his canine balls as his climax was only moments away. The bitch was raising her ass higher in the air, exposing the full creamy length of her quivery pussy sheath to his pounding prick. “Fuck yeah. I bet she’s gonna cum soon!” Jacob muttered, having learned slightly more about the topic of sex from his school buddies then his less informed sister had so far. He was stroking at his cock through his jeans even harder now, as he wondered about how good a girl’s pussy would feel, bumping along his cock-shaft, back and forward. The delicious ecstasy the bitch was experiencing was fervently imagined their teenage minds, as they both observed Lucky continuing to drive his fantastic boner, slamming deeper and deeper into his furry little fuck-buddy’s cunt, the rigidity of it sawing gloriously inside her throbbing doggy tunnel. “Ooooooher!” Megan hummed absent mindedly, her own little cunt creaming hotly at the sight, while imagining what the female must be feeling at that moment. Just then, the little bitch exploded into a wild climax. She howled and yipped pitifully, as hot fuck-cream gushed out of Lucky’s big, exploding cock-head, filling her knot sealed fuck-hole with his cum. Shuddering violently, the twitchy little bitch was frantically screwing her spasming cunt back tighter around the thick base of his belching cockshaft. A huge amount of his cum was pumping into her squirming pussy as the casual canine couple got there fetid doggy rocks off together. The kids waited until Lucky finally plopped his shriveling cock out of the bitch and sat down to lick his stinky cock and balls clean of her secretions. Then Megan decided to go out and bring him inside before a mean old dogcatcher could come along and drag his furry butt off to the pound. Knowing Aunty Linda would be coming home from shopping shortly, the twins scurried into the living room to watch TV, dragging Lucky with them as they went. Shortly thereafter, the twins’ very attractive Aunty Linda arrived home just in time to start preparing dinner for them all. She beamed a stunning smile at the kids, before disappearing into her bedroom to change into something more comfortable for around the house. Meanwhile, the twins tried to focus their attentions on the cartoons they were supposed to be watching. However, their fevered young minds were on what they’d seen the horny dogs doing on the front lawn that afternoon. Though they didn’t say anything to each other about it, that’s all the children could actually think about. It didn’t help Jacob’s aching young balls when his lovely Aunty passed back through the lounge room on her way to the kitchen again. She was wearing an almost see-through pink negligee ensemble, under an almost gossamer thin house coat. Aunty had already explained to the children that since her husband had died, she’d gotten used to her privacy and getting about the house dressed as she pleased. Still. Jacob’s young eye’s had been constantly fighting his otherwise polite attempts to keep them from roaming all over his gorgeous Aunt’s buxom body during the week the twins had stayed with her already. Despite admitting to being a little lonely lately, Aunty Linda was a really fun loving, free living woman in her early forty’s, with an awesome, fully padded out, female figure. The twins had loved staying at her place for weekends and holidays ever since they were really little. But now as a developing teenage boy, Jacob felt his cock twitch in his Levi’s as he ogled at her big, round, bouncy tits and nicely rounding ass, as she wiggled her way past him. Damn! She’s a sexy old woman! Jacob told himself as he caught a horny glimpse of her scanty white nylon briefs and clinging d-cup bra, beneath the flimsy, floating garments she was wearing. Jacob found himself imagining how nice it would be to hook his thumbs into Aunty Linda’s panty waistband before stripping her panties slowly down her full-swept thighs. He imagined her spreading her legs for him and sighing as he began licking at his beautiful Aunt’s hotly oozing pussy; tasting her nice hot cunt as it leaked hot fuck-juices into his naughty young mouth. God. It gave him thrilling shivers all over when he though about perverted shit as that. He wondered guiltily what his mom would say just now, if she knew her horny little son was thinking about fucking and sucking with her own, sexy elder sister. During dinner that evening, Jacob kept glancing at his Aunt and sister, vividly recalling how exciting it had been to watch Lucky’s big hard dog-cock fucking into the stray bitches pussy. The kid had been walking around with a hard-on since that afternoon, and the aching feeling in his jiz filled balls just wouldn’t go away. As the evening slowly dragged along, Jacob kept secretively glancing at his voluptuous Aunt’s, hot womanly body, when ever he figured she wasn’t looking. He couldn’t get his mind away from the fucking action he’d witnessed, and as soon as he went to bed, the horny kid began excitedly beating his teenage meat. He was almost on the verge of busting a nut when the door opened and Megan tiptoed into the room. He pulled up some covers when he realized it was only his sister, but he still got a funny feeling in his cock when the light from the hall silhouetted her naked body through the thin material of her nightie. “Are you awake bro?” she whispered, padding over quietly and sitting her cute, little round ass down on the edge of his bed. “Yeah,” he grinned, turning on the bedside lamp. “I can’t get to sleep at all.” “Nah, me neither,” giggled Megan. “I keep thinking about the dogs fucking.” She admitted with a little blush. “Me, too.” “Jacob,” she asked, her face slightly flushed with embarrassment, “did you really have a hard-on when you were rubbing the front of your pants today?” “Fuck yeah,” he grinned. “What does it feel like when a boy gets a hard-on?” “Awe shit sis, it’s really good and bad at the same time. It gets so achy and hot, that’s why I was rubbing it, I just wanted to make it feel better.” “Do you have a hard-on now?” his sister asked excitedly, while peering down at the blanket to where his crotch was. “No,” he answered honestly. He had quickly lost his erection when Megan had unexpectedly walked into the room. “Jacob.” She hesitated. “Will you show me your cock?” “Why?” “Well,” she giggled. “I remember seeing it when we were younger, but I’d like to see it now that you’re bigger.” “Fuck.. No way sis.” He blushed. “Dad would kick the shit out of me if I did, and he wouldn’t be happy with you very much either!” “He wouldn’t know about it, I wont tell anyone!” she assured her brother as she decided to throw in a little deal sweetener in for her brother. “If you’ll show me your cock, I’ll show you my pussy if you want. Ok?” “Really?” “Sure.” The cute little redhead grinned. “We could sort’a trade looks, I’ll let you look at my puss, and you show me your prick.” “Okay,” Jacob agreed, throwing back the covers. “Here it is.” The young boy always slept in the buff and Megan’s eyes almost popped out of her head when she first saw her brother’s prick. She’d expected to see a big vein covered thing, at least as big as she’d seen Aunty Linda’s Labrador dog fucking his bitch with. So she was stunned when she first saw her bother’s adolescent cock, dropping down at rest. It was about as long as her middle finger, only thicker. “Gee,” she gasped. “It sure isn’t very big.” “It gets a lot bigger when I have a hard-on,” he explained. Feeling slightly let down, she just stared at the pale, blue-veined prick that ended with folds of uncircumcised skin over the head. It seemed strange to her that there was only a light growth of red fuzz around the base of his limp dick. Her brother’s little ballbag seemed so pink and hairless. “Is it all right if I touch it?” she whispered. “Sure.” He grinned. “I’d like that a lot Sis.” When his sister nervously placed her trembling finger on his limp prick, he couldn’t get over how nice it felt to have her touch him down there. Her hand was so soft and gentle, that her touch made him shiver with excitement. Megan’s warm exploring fingers moved down onto the spongy surface of his young balls. Thrilling his quivery young dong as she smoothed her hand down its silky, skinned shaft. Cupping his balls tenderly then, she squeezed them, feeling the warmth of the crinkly skinned scrotum and the hardness of his cum jism filled balls inside. “What do boys call these these?” she whispered, excitedly feeling his balls. “Oh.. They’re my balls, or my nuts,” he explained. “They store up the cum I shoot out of ’em.” “Gee, boys are funny,” she giggled, still gently fondling his youthful, grape-sized balls. “I like touching you. My pussy is getting all hot and wet while I’m doing it.” She confided with a blush, while sipping panty little breaths. “I’m glad you like it Sis.” He grinned. “It really feels really good to me when you do it too.” Releasing his balls, she began tenderly caressing his limp prick with her loving, curious little girl’s hands. She couldn’t get over how nice and warm the velvety skin felt against her trembling fingers. His cock reminded her of a warm, fat worm in her palm as she closed her fingers around his prick. Giving his cock a loving squeeze as she instinctively pulled back on his loose foreskin, she was pleased and excited to see the end of his pink, cock-head peeking out. “Hey, do that again,” her brother urged, loving the way his sister was fondling his cock. “Pull the skin on it back and forth.” He advised her. When Megan did as he suggested, he could feel the wild pleasure streaking up and down his cock as she popped his cock-head in and out of his foreskin rhythmically. Shit, it felt a million times better than jacking himself off. Getting hornier by the second, Jacob could feel his cock starting to twitch and swell. His veins stood proudly against his sisters cool, fretting young hand as she marveled at her brothers impressive penile transformation. “Hey!” she giggled, as his cock started to throb and swell in her gently wanking hand. “It’s moving.
