"Oh, God, I'm scared, Bill."
"This is your last chance, Sis. Do you want me to forget about this?"
"Oh, no, Bill, don't do that! I want you to shove your big hard cock up my ass! I want it! I need it! I'm just scared," Jody blubbered, feeling hot tears trailing down her flushed cheeks.
"Good girl," Bill said, patting her ass gently. "And don't forget what I said. Even though it'll probably hurt you at first, you'll end up loving it and begging for more!"
"I-I hope so," the young girl said, her voice quavering with fear and excitement.
With his free hand, Bill gripped the massively swollen length of his hard prick. Its cockhead was purplish and visibly throbbing.
"Ungh, don't think my cock's ever been so hard," Bill groaned.
Jody felt waves of incestuous passion wash over her entire body at her brother's words. And her asshole quivered in anticipation of the fucking she was about to experience.
"Ohhh, Bill, hurry up! Fuck my ass!" she cried whorishly.
"That's better!" Bill said with a hoarse chuckle. "I'm gonna fuck your ass good and hard!"
Jody groaned as she felt the pulsing head of her brother's big cock pressing into the tight split of her ass mounds. She felt her smooth, white asscheeks being painfully forced apart. And she felt the hot, juicy prickhead pushing insistently against her tight little virginal asshole.
The young girl waved her ass about in a fit of incestuous lust for her brother.
Bill watched her sexy actions and he grinned. He really got off on the fact that even though Jody had never been fucked in her ass before, she was desperate to feel his prick inside that tiny hole. He pushed his cockhead harder against her resisting asshole.
"Ohhhh, God, it's gonna tear me apart! Your huge cock is gonna hurt like hell!" Jody whimpered.
With a brutal thrust, Bill fucked his prick violently against the tight opening of his sister's cherry asshole.
As Jody felt her brother's huge cock fucking into her little shitter, lust and excitement coursed through her young body.
With a husky animal-like growl, Bill fucked forward as hard as he possibly could, determined to sink the full length of his pulsating prick to the hilt inside his sister's ass.
"Yeeeeooowww!" Jody cried as she felt the sudden stretching of her tight ass ring.
Pain and pleasure warred within the teenager for a few breathless seconds. Then, the two sensations merged, becoming as one. Jolts of pain-and-pleasure-filled ecstasy washed over Jody's body, and she felt an incredibly intense arousal overcome her.
"Ohhhh, it hurts but it hurts in a good way. I love it, Bill! I love the feel of your cock in my ass!"
"I knew it!" Bill crowed triumphantly. And he fucked forward again, this time managing to shove his entire prick into his sister's asshole, his balls now pressed against her trembling ass.
"Aaarrrghhhh! Yesssss!" Jody sobbed, loving the feeling of being completely impaled by her brother's ass-splitting prick.
Bill grunted as he began to slip his thick cock out of Jody's tiny asshole. He drew it out slowly, inch by inch, until only his throbbing cockhead was still rimmed by the girl's rubbery asshole.
"Hurry! Fuck into my ass again!" Jody squealed, wriggling her ass about impatiently.
Now that she had finally felt the boy's cock inside her asshole, all feelings of fear had left her and all she felt now was lust and pleasure. She couldn't wait for Bill to fuck into her ass again.
Bill fucked his cock into Jody's asshole again.
"Ohhhh, yesss, fuck my ass, Bill!" Jody whimpered, bending over so far that she had both of her palms flat on the floor. Her body was loose and supple. So she didn't have to worry about any cramping sensations in her back or legs.
Bill started ass-fucking his sister with a slow, deliberate rhythm now. Each time he fucked into her, he buried his hardened prickshaft right to the balls within the hot, clinging tunnel. Then he outfucked his cock almost all the way before plunging back into Jody's ass again. And with each cock-thrust, his cum-swollen balls slapped lewdly against the spread lips of Jody's pussy.
"Ahhh, it's good, so, so good," Jody said thickly.
Each time she felt her brother's prick fucking into her ass, both her asshole and her pussy responded. Her asshole tingled and burned with pleasure and her ass muscles automatically clamped around the boy's thick prick, as if determined to hold it inside her for all time. At the same time, her pussy oozed out a steady stream of juice and throbbed with lust and ecstasy. Jody found herself wondering if it were possible to have an orgasm in both her ass and her pussy at the same time.
The young girl's fuck-juices were streaming into her asscrack, slickly lubricating her asshole for her brother's prick.
Bill groaned with pleasure. He had never fucked into such a small hole before, and it was made even tinier by the squeezing action of Jody's ass muscles around his prick.
Jody's asshole pulsated with her fuck-lust for her brother's prick, and hot thrills of incestuous pleasure shot through her pussy, making her entire body tremble all over.
"Ohhh, yess, Bill, fuck my ass! You're making me feel sooo good! I can't believe I was afraid of this!" she wailed.
And she began to shove her ass back toward her big brother's rutting cock. She moaned again and again as she continued to beg him to keep fucking her.
"I knew you'd love it," Bill husked.
"Yes! Yes! You were right!" Jody yelled and she clenched her teeth tightly together against the tide of primitive pleasure which threatened to overwhelm her.
Her naked little ass ground back against Bill's ass-plugging prick. Her strong ass muscles contracted hard around the boy's deeply penetrating prick as it withdrew. And the erotic pressure that was building up in Bill's balls increased.
Both of the incestuous lovers were moaning and groaning loudly and continually now, already close to orgasm. Jody's ass thrust forward and back in perfect time with Bill's cock-plunging movements. The young girl concentrated on working her ass muscles around the pistoning prick that was giving her so much intense pleasure.
"Oh, God, why haven't we done this before?" Jody said in a voice which made her sound drunk. And she was. She was drunk with lust. Incestuous lust. "It feels soooo good… I never know it could feel so good… keep fucking me hard, Bill!"
Knowing that they were both about to come, Bill pulled his prick even farther out of his sister's asshole. Now, just the very tip of his cockhead was still in the grip of her clutching ass muscles.
"Hurry! Ram it back inside meeeee!" Jody pleaded, shaking all over with sexual need.
With a loud cry, Bill plunged his entire prick back into Jody's ass. The girl could feel the flared cocktip penetrating her ass guts where nothing had ever gone before. She raised her head and let out a groan unlike the others. It was a groan which made her sound more like an animal than a human. And it was a groan which came from the very depths of her soul.
"Yessss, fuck my ass… harder… gonna come… Bill… keep shoving it into me like that… until I come… until you come… shove that hard thick cock up my ass again!"
Bill thrilled to his sister's voice and he heard the intense primitive need in her voice. He was only too eager to respond to that need and he pulled his prick far out of her again, pausing just a second before fucking fully back into her ass again with all the strength he could muster, which was considerable.
"Commmiiinnnggg!" Jody cried. Her brother's deeply penetrating cock-thrusts had done the trick. They had triggered the orgasm, which every cell of her body screamed out for.
Her tits flushed and shook, their nipples going hard, as hot incestuous thrills of orgasm washed over her.
As she came, her ass ring gripped her brother's cock even more tightly. It clenched and unclenched around the prick still fucking in and out.
