Around noon on the fourth day of their holiday, Sammie, the youngest girl, had been making sly comments and obscure hints all day. Finally her brother got her alone over by the fallen tree.
"Sam. What on earth do you keep going on about?"
"Well, let's say I was tired of swimming yesterday but Lizzie wanted to stay and sunbake by the riverbank. And let's say I came back to the cabin before her. And let's say..."
"How long before her?"
"Long enough. Long enough to see what my big brother was doing to our mother..."
"Oh fuck Sam. You didn't! Oh fuck. Sweetie you can't
ever
tell anybody. Sam, I..."
"What was it like?"
"Huh?"
"Fucking. What was it like?"
He was taken aback. "OK look. This is serious. We got carried away and it was just one time and.."
"It wasn't one time. You watch her and jack off all the time. And don't forget what you've been doing with Lizzie and me. Of course I won't tell, or they might find out about us three as well. So tell me, what was it like?"
"Bloody amazing Sam. Think of the best orgasm you ever had and double, no triple it. It's just the most wonderful thing, sex. Wonderful."
"Show me."
"What? No. Sam, I can't."
"You can pork your mum but not your sister? How so?"
"Because mum takes the pill. You don't."
"Lizzie takes the pill. Would you do it to her?"
"Sam don't ask me stuff like that."
"That's a yes, then. OK you owe me. One day,
soon,
I want one of those tripled orgasms from you, OK?"
She smiled. Mike had another incestuous idea.
"I've heard it can be pretty mind-blowing if your lover used their mouth, you know."
Sammie blushed, remembering she'd taken the end of her brother's cock in her mouth briefly to taste his cum.
"Sammie. I'll show you that if you want."
"OK. Um, now?"
"Over there by the old shed."
"Eeww no! Spiders and stuff... I know! The fork tree! Come on!"
His little sister's girlish enthusiasm was eclipsed only by her ingenuity. The fork tree had one central trunk extending up a metre, then it split almost horizontally in two before the two arms extended skywards. A person could sit in the crook comfortably, as Sam demonstrated.
"I can sit here. OK?"
Mike nodded. He was about to get his first taste of a girl's pussy on the same day as his first fuck.
Sam hooked her thumbs inside the waist of her shorts and pulled them down with her panties. She rested back on the tree, opened her legs and motioned to her brother. Mike knelt, eased her pussy open and her blonde fuzz aside with his thumbs, and licked tentatively at her slit. She trembled like she'd had a mild electric shock.
"Oh yes. That really is nice."
Mike went back to her salty pussy and began probing her with his tongue, licking up and down her pussy lips, and kissing at the little bud he found in the hood at the top. He knew about clits, but until now he'd paid no attention to one.
Sammie's mewling told him he was learning fast. She whimpered at his probing tongue in her pussy and bucked hard whenever his tongue flicked her tender young clitoris. But most of all she loved when her brother put his lips over her clit and sucked.
She began to exude salty cream which he lapped up eagerly. Sammie grabbed her brother's head and held his face hard against her pussy and crescendoed in a trembling frenzy. She almost screamed and bit on her finger to make sure she didn't. Still her brother's unrelenting tongue took her higher. She squirmed and throbbed against him so much that he nearly lost contact a couple of times, but always returned to the spot that was driving her crazy.
She screamed into her hand as wave after wave of ecstasy crashed over her. Her thighs clamped Mike's ears at the last, then her whole body shuddered twice before loosening all over. She slumped onto her brother, who tenderly held her steady as the last twitches faded.
"Oh Mikey. Thank you. Thank you. It was sooo wonderful."
"You mean like a triple?"
"Ooh, more like a double. But you can practice with me another time until you do manage a triple..."
He slapped the little minx's backside and made her squeal. Then she threw her arms tenderly around his neck and kissed him with real sensual passion, darting her tongue inside his mouth to fence with his own, not caring that she was simultaneously tasting her own love juices.
"Michael Delaney, one day soon you
will
fuck me."
"OK little sis. OK."
Night. A little rain made the cabin hot and humid. The father, Paul, snored loudly. He'd drank the last of the beer and was out for the count. The rest of the family lay fitfully on their beds, dressed only in tees and undies against the heat. It was still hot.
Suzanne peeked under the curtain to check on her daughters. They appeared to be asleep. She crawled over to Lizzie and saw her daughter laying on her back, one leg crooked wide apart. She wore loose underwear, satin shorts really, and in the dim light Suzanne could see the outline of her daughter's pussy against the fabric. She thought to herself: 'The little fox. I think she's shaved her snatch!'
Looking around to check she wasn't observed, she bent low to try to see. Gently she pulled the leg aside and now there was no doubt. Her daughter had a perfectly smooth pussy made all the more enticing with the sheen of sweat on her equally smooth thighs in the moonlight.
She checked Sammie, who was also on her back. Her top had ridden up exposing her flat tummy. 'I wonder if she's bald too?' She eased the panty leg aside and saw Sammie's blond fuzzy pussy, thinking 'Just like mine, only younger! I make pretty babies' she told herself.
Glancing towards Mike and thinking he was sleeping soundly, she decided to go outside hoping for a breeze. Sitting on the fallen tree, she heard rustling in the leaves behind her. Turning, she saw Mike, wearing only boxers. His smooth torso glistened with sweat in the moonlight. Whispering so as not to disturb the others, she said: "Hi honey. I thought you were asleep."
"Too hot. Good job the girls are asleep though, right?"
"Um, why?"
"They might be freaked out by their mum checking out their pussies."
She giggled. "Oh you saw. I was curious, that's all. Anyway I bet you've seen them plenty of times through the peephole in the shower. Gorgeous, aren't they?"
"Very."
