Harry Stevens - Hot horny sis

"Oops, maybe I should've kept my mouth shut," Betty sighed, recognizing the shock-wave she'd launched.

"Your timing isn't the greatest," Ruthie told her sister. "But as long as Carl and Len are involved, they had to find out about the rest of it sooner or later anyway."

"The rest of what?" Carl demanded to know. "What've Matt and Barry got to do with Len and me?"

"You heard Betty," Ruthie said, no nonsense now.

"Me, too," Ruthie revealed. Then she dropped the biggest bombshell yet. "And right now they're off someplace fucking Mom. And after she hears about what you guys have been up to with Betty and me, she'll probably want you to suck and fuck her too."

"Fuck my own mother?" Len choked.

"Mom's a dynamite piece of ass," Ruthie assured her brothers. "Betty and I can swear to that."

It was Carl's turn to choke. "You two made it with Mom?"

Ruthie and Betty both nodded. "The three of us took turns fucking with a dildo. Then Betty and I turned Mom onto Matt and Barry," Ruthie said.

Carl choked again. "What kind of crazy family is this?"

"One I wouldn't trade for any other family in the world!" Betty stated. "I've fucked around plenty the last few years, but sucking and fucking with my own family is the best trip there is."

"Betty's right," Ruthie agreed. "I'd still be cherry if it wasn't for family fucking. And so would you boys."

Carl and Len couldn't argue with their situ's last point. Earlier today they'd been nothing more than a couple of frustrated jack-off artists, and now Carl had his cock in Ruthie's cunt and Len was fucking Betty's asshole.

The boys looked at one another, silently trying to make up their minds where to go from here. Their sisters helped them decide, rolling their hips so Carl's prick moved in Ruthie's pussy and Len felt the rippling friction from Betty's tugging shitpit.

"And what happens after we're finished fucking you here today?" Carl asked.

"We hang together," Ruthie said. "All for one and one for all – no jealousy, no squealing on each other, up double-crosses. And no outsiders! One, big, happy fucking family."

"But what about Dad?" Len asked. "And if Matt and Barry are into it too, what about Uncle Bob and Aunt Aggie?"

"Right now they're the enemy," Ruthie said. "But as long as they're still family, you never know! Blood is thicker than water, and jizz and pussy juice are thickest of all."

It was the first time Betty had thought of their father, uncle and aunt as possible converts to incest. But by now she'd had enough experience with her kid sister not to sell Ruthie short. Therefore, she automatically backed Ruthie up.

"You can't lose with the stuff we use," Betty joked.

"Trust us!" Ruthie said.

"And fuck us!" Betty eagerly added.

Carl and Len were sold. "I'd rather sign on with the devil than go back to being cherry. Let's fuck!" Len cried.

So, their hard cocks in motion again, Carl and Len respectively resumed fucking Ruthie's clit in Betty's ass. Since each boy was operating from behind his sister, the girls faced one another. Ruthie took advantage of it by beginning to eat Betty's pussy once more.

"Mmmm," Len reported, "I can feel Ruthie's tongue in Betty's pussy while I'm fucking butt. It's practically like getting my cock licked at the same time I'm fucking!"

"I wouldn't mind trying something like that myself," Carl readily admitted.

"Well, the way we've got ourselves ganged up on each other now I can't get to Ruthie with my tongue," Betty told Carl. "But if you switch your cock to her ass, I can sure reach down and finger-fuck her cunt. It'll be like I'm jacking you off while you're fucking her butt."

Carl needed no further persuasion. Abruptly he yanked his prick from Ruthie's cunt. Then his cockhead mashed into the dent of the much tighter opening a notch away. After setting his hips he shoved, drilling his prickmeat into his sister's ass tunnel.

"Damn, I just love a cock up my ass!" Ruthie squealed, temporarily interrupting her pussy-eating. "Now finger-fuck my cunt, Betty, like you said you would."

Betty's hand was immediately down between her sister's legs, digging into Ruthie's pussy.

"Ooooh, can I feel that!" Ruthie rasped. "How about you, Carl? Betty finger-fucking my pussy deep enough so you can feel it with your cock in my ass?"

"Sure as hell," Carl answered. "It's a butt fuck and a hand-job at the same time."

"Then let's make sure Len gets the same treatment," Ruthie said.

She went back to eating her sister's cunt. The thin wall between Betty's pussy and asshole hardly seemed to exist, as Ruthie's tongue simultaneously stimulated her brother's prick and sister's cunt…

"Come twice as much is right," Len agreed. "And it won't be long for me."

"Me neither," Carl called back. "How about it, wanna shoot our wads in them together?"

"If you mean you gonna come now, I'm right there with you."

"Then here goes."

The twins strained, jamming their pricks to the balls up their sisters' assholes. At the same time in the girls' cunts, Betty swapped her finger-fucking for Ruthie's tongue-fucking.

The boys groaned with erotic release. The girls orgasmically moaned. All four of them were now coming at the same time. Hot jizz poured into female assholes from spurting cocks and pussies overflowed with bubbling honey.

The hung on to their climaxes along as they could but finally it was over. Their naked bodies gradually untangled, sagging in a row on the bedroom floor.

"Mmmm, that was utterly fabulous," Betty sighed. "Just wish Mom could've been here too. Can't wait to toil her when she gets back from fucking Matt and Barry." And suddenly Ruthie popped up. "Wait, I've got an idea. Let's not tell Mom about Carl and Len, after all."

"You mean keep these studs all to ourselves," Betty giggled. Then, getting serious, she added, "It's tempting, but we can't go behind Mom's back now…"

"Not a double-cross, silly," Ruthie said. "I mean that instead of just telling main about Carl and Len, what if she found out what studs they are first-hand? Now listen to this…"

Gail Barton could hardly wait to tell her girls about how things had gone with Matt and Barry. Her nephews and she had sucked and fucked out in the country for hours and after the sex came an earthquake of a conversation.

"After today," Gail had told the boys during the drive back to town, "I don't think I'll ever be able to settle for only one cock at a time again."

"Bet you'll have, trouble selling Uncle Scott on that," Matt laughed.

At the mention of her husband, Gail frowned. "Oh, him. Thank God we hardly ever fuck anymore. If it drops down to zero, your uncle'll probably, never notice."

"Yeah, that's pretty much the way it is with our folks, too," Barry sighed. "I think our mom is getting some on the side, though."

Matt was more surprised to hear this than Gail was. He challenged his brother to back up his suspicions about their mother.

"Well," Barry said with a smirk, obviously enjoying knowing something his brother didn't, "a few times when I've been going through Mom's purse to steal some change, I've found a matchbook from the same place."

"So?"

"The Playpen?" Barry jeered, naming a local so-called adult-motel. "C'mon, Matt, you know what a shack-job that joint is. Mirrors, waterbeds, fuck flicks on the TV. That's where Betty was putting out for Mr. Cobb, the science teacher, before we fucked."

Matt was forced to admit that Barry's evidence was convincing. Then the brothers noticed that Gail had just turned pale. They automatically saw she was shocked to hear about her older daughter getting it on with old man Cobb.

"Gee, I'm sorry to bring up that dirt about Betty, at The Playpen, Aunt Gail," Barry apologized. "Just didn't think you'd care after all that's gone down lately."
