"Gonna come, sis! I'm coming, sis! Jeez, what a cunt!"
"All of it," his sister panted fiercely. "Gimme that hot cm! Shoot it hot and deep, brother! Oh Lord I wanna fuck all night!"
Five minutes later her brother collapsed against her, but still Becky writhed and squeezed his soft cock. The urgent fucking motions of her soft hips finally began to subside, but already she'd started stroking and massaging his balls, craving more.
Jim rolled off Becky, heaving for breath. He stared down at his sister in astonishment. Her wide eyes shone lewdly on his prick and her sultry lips were parted and wet, still murmuring obscenities.
"Oh Jim, that was a great fuck, darling. Oh, brother, I didn't know what I was missing all these years! Listen, I want to try something different."
"Different?"
Becky nodded eagerly. She rolled over on her stomach and placed her folded knees under her so that her tawny naked ass hovered lasciviously in the air.
"You mean dog-fashion?" Jim asked.
"No," Becky panted. "I want it in my ass. Every burning inch, brother. Ram it in all the way! Lord, I'm so hot I could faint. Come on, Jim, shove it in. Hard."
"Christ, Becky, it'll hurt. You sure you can take it?"
She shuddered her beautifully rounded ass impatiently. "Don't worry about me. Just ram it in! Go ahead!"
The mere sight of his sister's succulent ass triggered a new rock-hard erection in Jim. Whoever else she might be, this wasn't the shy sweet sister he'd grown up with. First she'd given him the wildest blow-job imaginable, greedily gulping down his juices, then she'd taunted him into raping her and now she was pleading for it in her tender asshole!
Whoever had turned Becky on had started a bonfire in her loins. Jim would try to find out later.
He kneeled upright between the blonde's legs and spread the crack of her burning ass-cheeks. Her anus looked small beneath his big throbbing prick, tiny and utterly helpless.
"Maybe I ought to get some Vaseline," Jim suggested.
"Put some of my pussy-juice on it," Becky panted. "Put some on the head of your cock, too, brother. Then ram it home! Let's do it!"
He dipped his fingers into her drenched hot cunt and rubbed her freely-flowing pussy-juice around the puckered slit of her asshole. Then Jim spread some on the head of his pounding prick. Hunching forward with her silky ass firmly gripped in his hands, he shoved the red knob of his cock directly against her quivering asshole.
Then he lunged forward with all his might.
"God Almighty!" Becky screamed. "Tearing me in two! Jeeeeeezus Jim! Oh, my ass! Wooowww!"
The stunned blonde gasped, trying to catch her breath. The gigantic boiling pressure in her ravaged asshole felt like a blazing baseball bat rammed to the hilt. Her brother's thick hot prick throbbed fiercely in her narrow tunnel, surging with power, stinging like fire.
"Oh, shit, that's nice!" Jim groaned, digging his fingers into the tender flesh of her ass-cheeks. "Ooooh, sis, your asshole is terrific!"
Jim began pumping his gorged rod in steady strokes, each forward thrust bringing a cry of anguish from his sister's throat. It was impossible to be still, but with each slight movement of her naked ass, Jim's long prick inflicted new bolts of pain in her tender asshole. An idea occurred to Becky and she quickly darted her fingers down to her soaked pussy. She found her clit and began stroking it furiously, hoping the obscene thrills she got from fingerfucking herself would take her attention away from the pain.
Then something odd happened. The burning ripping pain pounding savagely in her hot asshole began to merge with the sharp thrills in her searing cunt. Sobbing, the blonde shoved a finger up her pussy, then two fingers, and began fucking herself eagerly. Both her tender slits were now crammed with pounding excitement.
"Yes, brother, yes! Harder, faster! Fuck my ass harder, brother!"
Jim didn't need urging. Her juicy tight anus boiled around his thrusting prick, squirming and wriggling to spark hot thrills along the length of his meat. The feel of his sister's tawny hot ass trembling madly in his fingers fired his excitement tremendously. What a hell of a way to spend Saturday night! The night was still young and so far he'd screwed his sexy sister in three different places, all of them wildly sucking on his cock.
Becky's naked body thrashed wildly on the bed as she furiously stroked her fingers in and out of her throbbing cunt. She was as excited by the idea of having her own handsome brother ravage her anally as the maddening experience itself. In her state of lewd delirium, she could no longer tell the difference between the gorged blazing sheets of pain rippling through her asshole and the lustful thrills racing through her soaked pussy. She felt completely crammed full except for her mouth. Lord, if only she had a cock to ram in there, too!
"Coming, sis! Oh, your hot wild ass, honey. Wow! Oh, that juicy asshole, mmmmmmmmm! Here it comes! Oh, baby swing that ass!"
In a fever of passion, Becky swung and jerked her naked ass with loud moans of joy. She felt her bowels tinge madly as her brother's load began to spurt deep in her asshole.
"Oh, yes, shoot it in me! Shoot it in my ass, brother! Ooh, Jim,love your prick up my ass! Fuck me darling! aaaaaah!"
He was coming in great molten gushes in her burning anus, spurts that flooded her churning ass in torrents of wet fire. She masturbated to a frenzy as he came in her impaled ass, her blazing cunt exploding with thrills. She flexed her anal muscles powerfully to drain her brother's load, swinging her cheeks up and down frantically.
When Jim suddenly pulled his cock out with a grunt, Becky shuddered from head to toe. Then she stayed in position, waves of delight coursing through her ravaged ass as Jim's burning come trickled and tingled. She slowly undulated her ass with obscene pleasure, moaning low and deep.
"Jesus, what do you do for an encore after that, sis?"
"Don't worry," Becky sighed, rolling over on her back, "I'll think of something, Jim. You just keep that beautiful rod ready to go, brother. Mmmmmm, that hurt gloriously. Do you suppose Dad ever did that to Mom?"
"Nah, I don't think so. Mom is too square. Now you tell me something, sis. Who took your cherry and turned you on? I mean, whoever he was, I gotta hand it to him."
Becky lit one of the cigarettes she'd stolen from her father's room. "Well, if you like," she said lazily, "you can congratulate him when he gets home tonight."
Jim's eyes widened. "Christ, you mean Dad?"
"You bet I mean our father. And brother, is he hung! To think that Mom has been getting every loving inch all these years," Becky sighed, stroking her brother's limp cock with her hot fist. "I'll tell you something else too, Jim. Your father could give lessons in pussy-eating. His cum is saltier than yours, too. But he doesn't have as much," Becky consoled her brother.
"I'll be damned," Jim muttered. He knew his father had a reputation all over town for being a stud, but fucking his own daughter! Well, what the hell, he reminded himself sheepishly, she's my own sister too.
"Ever think about making it with Mom?" Becky asked him.
"Well, the thought occurred to me, but hell, you know Mom. She'd be shocked out of her wits. She's still got a fantastic body, especially her gorgeous tits."
"Don't be so damn sure about that," Becky said thoughtfully. "Mom isn't as square as she seems. I think it's an act, the respectable housewife routine. I'd almost be willing to bet she's making it with someone on the side. You know what, Jim? I wouldn't mind making it with Mom myself."
"Are you kidding?" her brother said, startled.
"Hell no, I'm not kidding," Becky laughed. "I don't suppose you've seen her naked lately, but I have. She's as sexy as anything around. I'd like to suck on those fabulous tits for an hour before I'd eat her pussy until she faints. Mmmmmm, I'll bet she's delicious!"
