Grinning, Ross hauled his big sister's asscheeks wide-apart and slid the head of his huge, throbbing prick into the wet, warm crack between her asscheeks. Then groaning loudly, he ground his prickhead into her little brown shit-hole.
"Oh, God, it already hurts so much!" Bev gasped, but this time her cry was one of excitement, not of fear.
Ross gripped her tightly around her slender waist and shoved forward as hard as possible. He drove his bursting cock deep into her tiny asshole in one swift, hard thrust, slamming her asscheeks back hard against his hairy crotch.
"Aieeeee!"
Bev shrieked in agony. She wailed loud and long from the pain which filled her tiny asshole. Ross' cock was super-thick, and he had driven it into her as deep as possible. His hard fuckmeat stretched the tight walls of her asshole painfully, and Bev began to wonder if she could handle this. As much as she longed to have her little brother fuck her up her ass, the pain was mind blowing, and all sense of pleasure had disappeared. It felt to the young, writhing woman as if she had a red-hot poker up her asshold and she shook her head from side to side fresh tears filling her eyes.
"Please take it out, Ross!" she begged. "It's too fucking much! Stop! Stop!"
Ross laughed and slapped her hard across her asscheeks again, watching her, white ass flesh turn bright-red from his slaps. "Shut up, bitch! I'm gonna fuck your… and that's it! I guess you'll just have to learn to love it! And I've got no doubt that you will!"
Beverly whimpered helplessly beneath the lust-driven boy. Again, she reminded herself that once Ross decided to do something, there was no way in the world to stop him.
Ross nudged his hips even tighter against her ass and his cock slid even deeper inside her.
"Omigod!" she whimpered, feeling as if she were being literally split in two.
She sobbed with pain and begged her little brother to stop raping her ass.
But Ross just grinned and clutched her tightly against him, savoring the feel of her body shuddering against him. He could feel her tight ass walls squeezing the sides of his gigantic prick and he moaned with pleasure.
Bev arched her back violently, trying desperately to shake the boy off her. But Ross growled and grabbed both of her huge tits, one in each hand, squeezing them hard. He cruelly pinched her stiff nips until she screamed in agony.
"Ohhhh noooo!" she yelled.
Ross pumped even deeper into her guts. He clutched her trim waist in his meaty hands. He held her tightly as she bucked back at him, then yanked her ass forward again, trying vainly to shake him off of her ravaged ass.
"It hurts! It hurts soooooo much!" she shrieked her head rolling wildly from side to side on the lawn.
Ross pushed her huge tits in his clenched fists, yanking them outward from her chest. He pinched them hard, bruising them in his frenzy of incestuous lust.
Again Beverly told herself that her brother would not release her until he had shot his load up her asshole. There was no point in pleading with him any longer. In fact, she thought, her pleas just seemed to turn him on more. And she knew he was enjoying her total helplessness as he did what he wanted to her.
Just as the young blonde resigned herself to her little brother's raping prick, she once again began to feel the stirrings of erotic pleasure deep in her loins. The pain in her asshole lessened. And the little pain which remained seemed to transform into pleasure.
"Oh, God help meee!" she whimpered, knowing now that she wanted this. As much as she struggled against it, she wanted her little brother to fuck her asshole.
"Soooo tight. Soooo deliciously tight… and hot," Ross grunted, shoving his fat cock in and out of Beverly's snug shitter.
He humped her harder and deeper, filling her with a fiery lust which she knew now that only his cum could satisfy. She wriggled beneath his invading prick, her wriggles no longer attempts to get away, but rather movements of pleasure-sexual pleasures. She pumped her hips backward, eagerly meeting his forward cock-thrusts with her juicy little asshole. She was determined to capture every single bit of incestuous pleasure from the massive cock reaming her out so delightfully.
"Oh, yesss, Ross! Fuck me! Fuck my little ass! It feels sooo good, Ross! I like it now! No, I love it now! It doesn't really hurt anymore! Well, it does, but I like it! I love it! It feels so good! Do it to me hard! Fuck my ass hard and fast, Ross!" Bev cried, hardly aware of her own incoherent words, she was so super-aroused.
She tossed her body to and fro, gleefully impaling her ass on the boy's virginal prick.
Ross laughed triumphantly and slapped her asscheeks several times. Then he slipped his hands around to her tits again and pinched her nipples hard.
"Yeooowww!" Bev wailed as the mingled pain and pleasure shot through her, but they both knew that she loved it.
"I knew it! I knew you'd end up loving it and begging me for more!" Ross crowed. "Didn't I tell you? Huh? Didn't I?"
"Yes, you told me! You were right, Ross, you were so right!" Bev cried, more than willing to say anything the boy wanted to hear, just as long as he continued to ass-fuck her so deliciously. "You were right, Ross! I love the way you're fucking my ass!"
Each time Ross plunged his cock into Beverly's shit-chute, he did it fully, impaling her on the full length of his meaty prick. And with each inward lunge, his loaded balls slapped wetly against her ass-crack.
"Jeeesus, this is the best! Had no idea it could be this good… asss tight… hots… squeezing my prick… God – don't know how long I can last… unnnggghhh!" Ross groaned.
This was the first fuck of his life, and the fact that it was his own sister he was fucking just served to heighten his pleasure. He was glad that he had decided to fuck the woman's ass for his very first fuck experience. No matter how tight her little pussy was, her ass had to be that much tighter.
Bev delighted in her brother's cries of pleasure. She was glad that she was able to give him as much joy as he and his cock were giving her. She concentrated on tightening her strong ass muscles around his thrusting cock, and she was rewarded with more moans of intense pleasure.
Ross knew that he was about to come. Pie had hoped to last longer, but fucking his sister's tight, clinching asshole was even more thrilling than he had anticipated. And now his cum rose up in his balls, churning and bolting, struggling for release.
"Come! Shoot! I want your cum!" Bev cried, sensing that the boy would not be able to hold back much longer. "I'm gonna come too, Ross! Hurry! Come with meee!"
"Sexy whore!" Ross cursed, driving his cock in and out of her tight asshole faster and harder. He clenched his teeth tightly together in a desperate attempt to control his ever-rising desire.
But suddenly the young teenager felt his balls tightening, and he knew the moment of truth was at hand. He clawed hornily at Bev's tits and thighs and belly, hugging her even tighter against him as he slammed the full length of his cock into her slitter.
"Commmiiinnnggg!" he gasped as the first blast of hot cum jolted from his cum-slit and shot into Bev's quivering asshole.
"Yessss, that's it! I want it! I feel it! Oh, God, that's sooo great!" Bev whined, thrilling to the heady sensation of her baby brother's hot cum spurting up into her ravaged asshole.
His thick spunk burned into her ass walls and she quivered all over.
Her shit-chute was already stretched to the absolute limit around her brother's huge prick. And now his cum was filling it up even more again and again, she cried out in pleasure as the boy continued to shoot his load into her fucked out asshole.
Ross cum overflowed from Beverly's cock stuffed asshole and began to pump out around the bas of his jerking prick.
