Each time he fucked his big prick into her tight asshole, she squeezed and pinched it with her incredibly tight ass muscles. Over and over, Hank drove his big cock in all the way up to his balls, then pulled it out as far as he could, then fucked in again, then out, then in.
Wendy milked his fucker with her ass muscles and shoved her ass back and forth in perfect timing with his cock-thrusts. She ground her ass against his wet, cum-laden balls, which slapped rhythmically against her ass crack.
Sweat poured down Hank's face and splashed onto his sister's back as he fucked her ass harder and harder. Her face was red and contorted with exertion and she could hardly breathe, they were fucking so furiously and frantically now.
The young girl had never felt so anything so good or so exciting. Having her entire asshole stuffed with hard, hot cockmeat was an incredible sensation. She had never been fucked up her ass before, and she was thrilled that it was her very own baby brother who was popping the cherry of her ass. Maybe it was too late for her brother to pop the cherry of her cunt, but he was doing a damn good job of fucking her asshole right out of its virgin state and into sweet, hot ecstasy!
Hank fucked in harder, only to jerk back again and then cram even more lusty cockmeat into her spongy asshole, spurred on by her grunts and moans of passion, and her frantically erotic movements. Her asshole was larger now, giving him a soft, well-worked velvety tunnel to fuck into.
Over and over, Wendy contracted and relaxed her ass muscles as Hank continued to shove his rock-hard prick in and out of her twitching asshole. As she writhed obscenely beneath him, the tight fit of her hole and the vibrations of her ass muscles against his cock all worked together to churn up his cum. He could feel his jism boiling in his balls now, and he knew there would be no more holding back, he had to come.
Wendy felt him tense and his prick twitched inside her ass in a different way. She knew that he was about to come.
"Do it, Hank! Shoot your hot cum up my ass! I need it! Oh, God, I have to feel your cum inside me!" she cried, wriggling her ass even more violently.
Hank grunted and fucked her ass hard, sinking his hot cock up her tiny asshole with slick, hard fuck-strokes.
"Yeah! This is it! I'm gonna pop! Awwww shit… I'm coming!" he yelled as the thick hot cum they had both been waiting for shot from his cum-slit and splashed lewdly into his sister's quivering asshole.
Feeling her brother's cum shooting into her virgin asshole brought the young girl off, and she came too. She exploded underneath her brother, calling out his name, moaning with passion, begging for more cock as she reached an orgasm so powerful that it amazed her, taking her breath away.
Her climax shuddered through her dripping pussy as her brother's cock continued to spew hot spunk up her ass. His prick twitched and danced obscenely inside her asshole as he shot wad after wad of thick hot jism, more cum than he had ever shot before.
Wendy lay limp now, exhausted from the thrill and exertion of her first ass-fucking. Slowly, he pulled out his long cock. It was, amazingly, still hard! He held his prick in both hands and sprinkled the last drops of his cum over her flushed asscheeks.
Then he lewdly rubbed the warm gooey cum into the soft cheeks of her ass, swirling the thick white jism across her still-trembling flesh.
He rolled over onto his back. His flushed face wore a pleased, triumphant look. His cock stood high in the air, throbbing again – as though it hadn't just spewed out a flood of cum.
Wendy reached over and kissed the spongy head of her brother's prick. Her long blonde hair fanned out on either side of his prick.
"God, that was great, Hank! I loved my first ass-fuck! Thanks for making me feel so fantastic!" she murmured, running her tongue up and down his rigid prick.
CHAPTER SIX
A couple of days later, the four Dayton kids were out on the beach, alone once again. Hank and Phil were tossing a football back and forth near the shoreline. Wendy and Candy were lying on a big beach towel farther up from the water. They lay on their stomachs with their chins propped up on their hands as they admired their sexy, handsome brothers and exchanged horny thoughts about the two young boys.
"What's goin' on with Mom and Dad these days, do you know?" Candy asked idly.
Wendy shrugged. "Not really. I just know they've been arguing a lot lately. And something's been going on at that house down the beach that they're always goin' to."
"What do you mean?" the younger girl asked.
"I'm not sure. I've just overheard a couple of arguments where Mom said she was going down there and that Daddy didn't have to go if he didn't want to."
"But Daddy always goes with her," Candy said, confused.
"Yeah, I know. I heard him telling her that he didn't trust her to go there alone, and that he'd go with her every time she got it into her head to go down there."
"Jeez! I wonder what it's all about," Candy said, feeling really intrigued and curious now.
"You know what I think?" Wendy murmured with a mysterious smile on her beautiful young face.
"What?" Candy asked, really interested now.
"I think," Wendy began, turning on her side to face her sister, "that they're into some kind of swinging parties that go on at that house down the beach."
"Swinging parties? You mean swapping and all that?"
"Exactly! A few things I overheard really make it sound like that's what's going on. And I think Daddy's not into it as much as Mom is. I think he's jealous because of some guy she keeps wanting to fuck!"
"Wow!" Candy cried, totally surprised by what her sister was telling her.
Wendy laughed. "Yeah, I know. Isn't that hot? To think of Mom and Dad…"
"Wow!" Candy cried again. "Poor dad, if what you say is true."
"I know," Wendy agreed. "I feel sorry for the poor guy if Mom's really into fucking some other dude."
The girls fell silent then for the next few moments. Candy's pussy was already burning and itching from the thought that maybe her father would want to fuck her now – especially if he wasn't getting any pussy from her mother!
Suddenly Wendy laughed and clapped her hands, breaking into the younger girl's thoughts. "Look at Phil! Isn't that great? God, is he built!"
Candy looked at her brothers. Suddenly, she wanted to shock her sister just as much as her sister had shocked her with the news about their parents. "Guess what Hank and Phil told me," she said innocently.
"What?" Wendy asked, glancing at her sister and thinking how beautiful and sexy the young girl was.
"They think that Daddy and I have the hots for each other!" she said, giggling nervously.
"Well? Do you?" Wendy asked coolly.
Candy giggled again. "Well, I can't answer for him, but I know that I'd give just about anything to have him fuck me."
Wendy laughed, feeling her pussy growing warm. "That's great! I kinda thought you had the hots for him. I've seen the way you've looked at him, especially at his crotch. Bet he's got a really big cock!"
"Yeah, I'll bet," the younger girl said, blushing with excitement.
"And I'll tell you what I think," Wendy murmured.
"What?" Candy asked curiously.
"I think that Phil and Hank are right," she said, watching her sister closely for her reaction.
"What do you mean?"
"I think that Daddy's just as hot for you as you are for him. In fact, I've noticed the way he looks at both you and me… has for some time now… but especially at you."
"You mean it, Wendy?" Candy asked, her pussy burning hotter and hotter at her sister's words.
"Sure, I mean it. No kidding, Candy. A lot of times, I've watched him when he didn't know I was noticing the way he was looking at you."
"What way? What do you mean? How was he looking at me?" Candy asked, unable to keep the excitement from her voice.
