Harry Stevens - Hot horny sis

She folded the elastic over at the waistband, then doubled it again. And again. The soft roll of her lower belly sloped in exposure, downy with golden fuzz which get up from her still-hidden pussy. Gradually, the panties crept down, folded a fraction of an inch at a time. Now the wispy curls of Betty's bush showed.

"Don't think this is gonna cool me off a bit," she said to Ruthie. "I'm getting hotter every second."

"Here, maybe I can help," Ruthie said, stifling her giggles while the boys followed the strange proceedings in silence.

Ruthie left the bed and went to her practically nude big sister. The panties sagged halfway down Betty's hips now, revealing more than a teasing hint of her cunt's blonde triangle.

"You just relax, Sis," Ruthie cooed. "Let me do the rest."

Kneeling before her sister, Ruthie took over the removal of Betty's panties. Bit by bit they dipped, then finally they no longer covered anything of importance. But Carl and Len couldn't see Betty's cunt because Ruthie's head was directly in front of it.

"See if this cools you down," kid sister said to big sister.

Ruthie blew on Betty's cunt. In response, Betty's hips jerked.

"Ooooh, that makes me hottest of all," Betty moaned.

"I was hoping you'd say that," Ruthie answered, finally allowing herself to giggle out loud.

Without hesitation, Ruthie now planted her mouth on Betty's cunt. Betty's loins began to circle sensually, the way they would if she were getting fucked – for, in a sense, indeed she was.

She murmured. "Oh, yes, Ruthie, yes. Tongue, tongue, tongue. Keep moving it inside my cunt. Feels almost like a cock. Fuck my pussy with your tongue, Sis, and I'll come in your mouth."

Ruthie's slurping filled the room. Then Betty's orgasmic moaning temporarily drowned it out, as she climaxed in her kid sister's face. And, after that, Ruthie's slurping took over again, signaling her thirst for the female cum oozing from her big sister's pussy.

And finally one of the boys found his voice. "Jeez, Ruthie and Betty are gay!"

"No," Len answered Carl, "they're only gay if they only make it with other chicks. When they swing both ways between cock and pussy, they're bi, I read about it in a magazine."

Overhearing them, Betty called, "That's right, boys. Bi's the word. 'Course for a girl to go both ways while she's having her pussy eaten by another girl, she needs the, uh, right kinda input from the other side."

Carl and Len turned toward one another, simultaneously whispering, "She wants some cock!"

"You bet I want some cock. And if I know Ruthie, she wants some too. So how about it, boys?"

Carl and Len jumped to their feet, their jutting cocks twanging. Then, approaching their sisters, they breathlessly discussed who would do what to whom.

They quickly agreed that Carl would take on Ruthie, with Len trying on Betty for size. Betty said that sounded super to her. Ruthie was too busy eating pussy to speak, but she shifted onto all fours so she could be dog-fucked.

Carl went first, slipping his prick into Ruthie's pussy from behind her. She immediately began tossing her hips, giving him plenty of the movement and friction he craved.

"Well, I'm in solid," he called to Len. "Now it's your turn."

Len approached Betty from in back. However, when he arrived within the length of his dick, he realized he'd miscalculated.

"Shit!" he blurted. "How can I fuck her pussy when Ruthie's already eating it?"

And, over her shoulder, Betty calmly answered him, "Since when is a girl's pussy the only place she can take a cock? If you read enough dirty magazines, Len, you ought to know that."

Catching on, Len stammered, "Y-you… mean?"

"Straight up my ass, brother dear," Betty confirmed. "I just took a shit before I wandered down the hall, so the muscles are still nice and stretched. Your big cock'll just slide right up my ass."

"Jesus!" Len gulped. "Losing my cherry with one sister and fucking the other one's ass, all in the same day. Unreal!"

While Ruthie continued to eat her pussy, Betty reached behind herself and spread her rear cheeks. The dusky eye of her asshole seemed to wink at her brother, especially when she playfully failed.

As the aroma made hit nostrils flare, Len choked to Betty, "Could I eat it a little bit first, Sis?"

"Only if you use plenty of tongue," Betty replied. "And ill fart some more, you've got to promise to suck it up."

"Damn, I'd eat your shit, Sis," Len recklessly vowed.

"Don't worry, you'll get a taste if you give my ass a rim-job," Betty chuckled.

Len knelt, immediately wedging his face between the cheeks of Betty's ass. Then his tongue briefly swirled around the rim of her asshole.

"Stick it in!" Betty urged.

She failed again, opening up the narrow ass tunnel so Len's tongue could surge inside. And the instant he was rimming her ass, he could feel the bump from Ruthie's tongue a notch away in Betty's pussy.

"Ooooh, that's it," Betty moaned, "rub your tongues together. Make me come in both holes at the same time."

Len and Ruthie strained to satisfy Betty's orgasmic craving. Within seconds they had succeeded.

"Fantastic coming!" Betty swooned.

And, all at once, Ruthie was coming too. For as she'd been tonguing Betty's pussy, her own cunt had been steadily dog-fucked by Carl from behind. The friction built until Ruthie's senses exploded.

"Mmmm, I know my kid sister's coming," Betty sighed. "I can feel the vibes."

Then Betty held Ruthie's head while the latter clutched her big sister's loins and they lingered in the glory of their shared orgasms. For a moment it was almost as if Carl and Len had been forgotten. But the boys were too horny to remain ignored for long.

"Hey, Ruthie, I'm the one fucking you," Carl snapped. "You're only coming 'cause it's my prick in your cunt. Like this!"

He thrust his prick so hard and deep in Ruthie's cunt that she reared up from Betty's cunt and squealed. Then, after temporarily pulling out until only his cockhead remained, he rammed her again.

"Oh, you're right… so right, Carl," Ruthie croaked.

"It's your cock in my cunt that's got me coming like this. As long as you fuck me, you're the boss. All I want to do is keep coming, coming for you!"

"Hear that Len?" Carl called to his brother. "I shaped the bitch up fast. And unless you're a wimp, you'll do the same thing to Betty. Give her your cock back there and make her beg for more!"

"Yes, yes," Betty agreed with Carl. "Fuck me where I shit, Len. Fuck my butt with your big, hard cock!"

Len got to his feet. He shoved his prick between Betty's asscheeks while he and his sister were both standing.

"Higher, just a little bit higher," Betty rasped, directing his cockhead toward her tightest fuck-hole. "There, that's it! All you have to do is shove your cock in and you'll be fucking my ass."

Len gripped her hips, spreading her plump asscheeks as he set his loins, then surged. His rigid cock shot into her ass chute, not inch by inch but the whole thing in a single thrust.

"Ooooh, you're ripping me! Ripping me so fucking good!" Betty groaned with welcome pain. "Nothing gets me off like a big, mean cock up my butt."

She climaxed on the spot, rubbing her pussy to go along with the prick in her ass. Female cum dripped through her fingers and trickled like piss down her inner thighs.

Then Betty called down to Ruthie, "Hope you're coming as much from Carl's cock in your cunt, Sis, as I am from Len's cock in mine."

"God, Sis!" Ruthie called back. "If I was coming any harder I'd pass out. What a couple of studs!"

Betty enthusiastically agreed that Carl and Len were true cocksmen. Then, making a comparison, she blurted, "Neither Matt or Barry fucked me any better than this."

With their big sister's surprise mention of their cousins, Carl and Len abruptly froze in mid-fuck. Ruthie just shook her head, sighing in response to the can of worms Betty had now recklessly opened.
