Mark Carver - Auntie in the middle

"Ten seconds!" Jack warned, glancing at his watch. But he knew he could get his rocks off any second. Not just because of the brunette's hotly sucking mouth, which whipped and slammed back and forth on his cock with juicy lust, but because he could also sec his naked sister panting passionately as she brutally fucked Linda. Jesus, what a vacation! In the pest two days he'd fucked and sucked his lovely sister and gorgeous aunt, and now he was in bed with both of them!

"Five seconds!" he warned Linda. But the brunette barely heard him any more. Between the hot thrilling young prick in her mouth and the massive jolting rod in her pussy, the furiously aroused teacher was almost beyond caring about anything. And Sherry's finger was wriggling crazily in her tender asshole, firing her lust to deep frantic moans of joy.

Then the whip began coming down, viciously and steadily on Linda's naked hot ass. With each racking bolt of agony, Sherry thrust the massive prick inside her faster and deeper, keeping the shocks coming for a steady twenty seconds. The madly moaning brunette could only crave more of everything – the immense gorged rod tearing deep in her stinging cunt, the electrifying sheets of fire in her loins, the deliciously cruel jolts of pain tearing across her crimson hot ass, the blazing cock threatening to burst in her mouth.

Suddenly Sherry withdrew the dildo and the maddened brunette cried deep in her throat, wriggling back frantically to beg the girl to ram it up her inflamed pussy again. And the fiery pain on her helpless ass became even more intense as Jack began to flail her glowing cheeks mercilessly.

Now Linda sucked on her nephew's rock-hard prick with every fiber of lust she could summon, trying desperately to coax his boiling load.

And the next moment she lost consciousness.

Because the most agonizing, ripping sheet of pain she'd ever, felt or dreamed of blazed explosively deep in her ass, burning, tearing, savagely gorging. In a moment of diabolical lust, Sherry suddenly slammed the nine-inch spiked cock as deeply into her aunt's tiny brown asshole as she could, with one violent thrust. And at the same time, she pressed the button that triggered the battery-operated shock, and held it down for thirty seconds.

The softly screaming brunette didn't know how long she'd been out. She only became aware, as she regained consciousness, that her nephew was spurting his fiery jism in her mouth in a series of hot bursts. Moaning in a frenzy, Linda swallowed the boiling flood gratefully, in greedy gulps. The whip had stopped its torture, but still the insanely burning monster was rammed up her ravaged asshole, lunging in and out cruelly.

A moment later her nephew had slipped out his deflated prick, with a long sigh of contentment. But still the torturing plunges slammed in and out the brunette's helpless asshole, each one accompanied by a sudden electric shock.

"Killing me!" Linda gasped, struggling vainly against her bonds. Each time she tried to wrench her ravaged anus free of the invader, the pain only became more intense.

And abruptly the pain became something else – sheer obscene ecstasy. A profound, breathtaking orgasm began rippling through Linda's loins as the tire in her bowels spread to her frenzied cunt.

"All of it!" the brunette screamed. "Give me every inch, darling. Fuck my ass! Harder! God, shove it deeper! Love it, love you Sherry, more! Ohhhhhh! Unnnnnnnf!"

Again and again Linda came as the lust-crazed blonde fucked her helpless anus in a fury of wanton abandon. But Sherry herself had become so aroused she needed her own reward. She cased the huge dildo out of her aunt's asshole, seeing it was covered with blood. Still, Linda sobbed and moaned and twitched her ass in violent, begging spasms.

"More!" she gasped, rolling her tongue around her mouth to lap up the lingering taste of her nephew's salty come. "Both of you. FUCK ME AGAIN!"

"I think we all boner take a break," Jack panted. "Let's smoke a joint."

Sherry unstrapped the monstrous cock and the three of them sprawled on the bed, catching their breaths as Jack lit up a reefer. Still tied down, Linda could only moan and gasp, her burning ass twitching convulsively. She inhaled gratefully when Jack offered her the grass, her eyes glazed, straying from Jack's long dangling prick to Sherry's golden pussy-hair. Would she ever get enough of her own beautiful niece and nephew? They'd triggered a hunger in her so violent, so deep the teacher felt she could have raw thrilling sex a dozen times a day and still feel insanely aroused.

"Let me eat your pussy," Linda begged Sherry in a whisper. "I'll give you the blowjob of your life, darling. I'll make you so happy, honey. Please?"

"No," Sherry said firmly. She held up the bloody dildo. "I want you to fuck me with this, Aunt Linda. I'm dying to see what it's like! But I'll be damned if I'll be tied down." She grinned lasciviously. "I like to dish it out, Aunt Linda, not get it."

"Tell you what," Jack spoke up, stubbing out the reefer. "Now that Aunt Linda's asshole has been broken in, so to speak, I'd like a piece of that myself." His limp prick began to pound at the thought. Her creamy hot ass had hypnotized him while he'd raped her in the mouth, while he'd watched those soft white mounds turn glowing red beneath the whip. And the memory of Sherry's tight juicy asshole earlier that day flooded his mind, sparking his desire. Damn, he loved those hot silky cheeks grinding against his crotch as he rammed his big meat home! He'd already had Sherry's succulent ass, but not his aunt's.

"So here's how we'll do it," Jack said, and he told them. His sister quickly agreed, but the brunette protested.

"What about me?" she complained. "When do I get to eat Sherry's hot pussy?"

"You're in no condition to argue," Sherry pointed out with a grin. "I mean, it was you who bought the rapes and the whip and this crazy cock, wasn't it? Of course, if you need any convincing, Aunt Linda."

Sherry picked up the whip and a tremor of fear raced through Linda's naked flesh. God, I'm at the mercy of my own sex-crazed niece and nephew, thought Linda with a shock. And deep down, I planned it that way! Humbly, she agreed to the position.

Her nephew and niece once again untied her, turned her over and bound her again. When Linda started complaining that she didn't need to be tied down any more, Jack silenced her by holding up the whip.

"Once I get my cock up your ass, you may decide to run for the hills," he told Linda, grinning. "Besides, Aunt Linda, when you get hot those damn fingernails of yours are like razors. I'd just as soon take on a leopard."

With Linda spread-eagled on her back once more, Sherry strapped the massive dildo-harness onto her aunt's hips and beneath her ass, buckling it tight. It poised upward like a giant ram. At least, Linda consoled herself, I can watch naked Sherry as she fucks me, even if I can't feel her luscious tits and ass.

Hotly aroused, Sherry climbed onto her aunt's hips, straddling her like a saddle of obscene ecstasy. While Sherry hovered her pulsing cunt over the knob of the waiting dildo, gripping it with both hands, her brother got into the same position Sherry had assumed minutes before – leaning back on his elbows between the brunette's spread legs, cautiously guiding his now-erect prick toward her naked asshole. With Sherry facing Linda, he could watch ever detail as his sister fucked the brunette.

And, Jack noticed with a stab of excitement, Sherry's asshole was also exposed and helpless. Just in case he wanted a little variety, he told himself. After all, the girl's anus was about as succulent and tight and hot as you could get at that age.

"Ahhhhh, that's good!" Jack groaned as he slid his throbbing prick deep inside the brunette's juicy asshole. "Shit, that's hot. I'm gonna dig this, Aunt Linda!"
