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.
