Mark Carver - Auntie in the middle

Jack dismounted her, heaving for breath. "She'll come any minute. Just cool it, Aunt Linda. Jesus, if you ever put that on the market, you'll get rich."

"Just once," Jack went on softly, grinning. "She won't hurt you, Sis. She loves you, you know. All she wants to do is eat you out while you're tied down. No whips, no dildo, no punishment at all. Hell, I'll protect you, baby. She's been awfully good to us. What do you say, Sis?"

Sherry began thawing. "Well… she has been sweet. I guess it's okay. No dirty tricks, though!"

Jack's face became utterly innocent. "Not on your life, Sis! None of that weird stuff for you. I'll protect you, remember."

"Now, remember, I don't go in for any of the weird stuff," Sherry said to them. "Easy does it with Sherry's body, okay?"

Smiling broadly, Jack picked up the whip and held it in front of Sherry's wide eyes. "Okay, you snotty bitch, it's vengeance time. Who in the hell do you think you are, giving everyone orders? You know what you need, tramp? Discipline. Punishment. A lesson!"

Sherry's young face turned ghastly pale. "You-you bastard! You bastard, you promised!" The girl began struggling fiercely against her ropes. "You untie me this… aaaaaaagh!"

Jack brought the whip down on her plump naked ass with a furious stroke, leaving wide red welts across the golden flesh. The white-hot pain pumped the breath from the girl's lungs. Jack handed the whip to his naked aunt, who stood beside the bed watching avidly.

Linda hefted the whip, looking doubtful. She really did love her wanton niece. But Sherry had been acting arrogant lately, like a sex-spoiled brat.

"Darling," Linda told her niece softly, "this is for your own good. Now you'll know what it feels like!"

And the excited brunette began stinging the nakedly bound girl's trembling hot ass with the whip. The first few lashes were almost gentle and careful, bringing low screams from Sherry's throat. But as the girl's ass-cheeks began glowing bright red, a fierce lust seized Linda. She began whipping her niece in a fury of vengeance and excitement, fascinated by Sherry's madly squirming young ass. Even Jack was startled by his aunt's sudden violence.

Beneath the savage whip, the helpless girl shuddered and twisted in maddening gyrations, attempting to escape the frenzy of pain. Sherry couldn't even catch her breath long enough to scream. She could only moan deliriously while tears gushed from her eyes. And beyond the blinding pain was something else – a deep wanton pleasure as her helpless young ass blazed with lewdly perverse joy.

She recalled how much her brother had hurt her the first time he'd raped her in the ass, and then how deliciously wild it felt in a few brief minutes. And now the very same thing was happening! Frantically, Sherry began swinging her plump ass upward to meet the lashing whip. She was having an orgasm! The hot pounding in her ass was quickly spreading like wildfire to her throbbing pussy, erupting there with molten ecstasy. Now the girl was craving the whip, becoming hooked on the fierce pain-pleasure ripping through her madly swinging arm.

Unable to realize what was happening, Linda's viciousness suddenly gave way to remorse as her young niece moaned and shuddered helplessly beneath the frenzied torture. Putting down the whip, Linda fell to her knees beside the bed and began lavishing tender kisses on Sherry's hotly sowing ass, licking the rosey welts with her long tongue, then snaking her tongue up the girl's succulent asshole in an apology.

"Dig it!" Sherry gasped, trying to explain she loved the whip, felt wonderfully helpless as she strained at her bonds. Sherry had already run a gauntlet of lust that most women didn't experience in an entire lifetime. Jaded by thrills that were too sudden and bizarre and much too intense in the past few days to her innocent young body or mind, the girl was rapidly becoming addicted to any new sensation, any new sexual kick – agonizing or blissful.

Because the passionate girl could no longer tell the difference between pain or pleasure when it came to sex.

"Linda," she whispered, undulating her hips lewdly, "fuck me with the dildo, Aunt Linda! Shove it all in me, darling! God, I'm so hot I could die! I've never felt this crazy before. Hurry!"

"I'll fix you, sweetheart," the excited brunette told her. "I'll give you the fuck of your life, darling niece! Just hang on for a minute."

Quickly, Linda strapped on the harness, thrilled at the idea of Sherry's helplessness. At last she was in control of the beautiful girl.

"Untie me," Sherry pleaded. "I won't run away. I just want to suck your tits while we do it, Aunt Linda!"

It was obvious to the brunette that Sherry couldn't be dragged out of the bedroom by wild horses in her current state of feverish lust. She quickly untied Sherry and the girl rolled over on her back, already thrashing her hips wantonly. Linda climbed on top of the perspiring naked girl as Jack came back into the bedroom. The sight of his lushly curved aunt mounting his passionately moaning sister sparked an immediate hard-on in the boy.

"Fuck me until I faint," Sherry whispered frantically to her beautiful aunt, wrapping her arms around her tightly. "Shove it in all the way, darling! Every loving inch! Aaaaaaaah!"

The panting brunette slipped the giant head of the humming prick inside Sherry's tender slit and instantly the moaning girl twined her ankles around Linda's and clutched her aunt's big creamy ass-cheeks in her fingers. Sherry rammed her mouth to the brunette's, sucking eagerly on her slithering tongue, beginning to claw Linda's hotly trembling ass-cheeks with her sharp nails. Lord, her aunt's fat burning tits felt wonderful crushed to Sherry's! The girl hunched down beneath Linda's hot nakedness to begin sucking ravenously on one of her luscious breasts while her aunt fucked her with slow, dreamy lunges of the colossal spiked prick.

Then Linda hit the red button for five seconds, and the blonde's tawny nakedness shuddered like a leaf in a storm, lewd screams of joy issuing from her throat.

His prick pounding with rock-hard power, Jack mounted his aunt from behind. He knelt with his knees placed between both their thighs, spreading his aunt's ass-cheeks with his hands. Choosing between her lusciously soaked cunt and her tiny naked asshole, Jack rammed his long meat into her silken pussy, sucking in his breath with lust. Fantastic cunt! Jack thought happily.

The three of them began to jerk in unison with their passionate fucking, a mass of sweating hot flesh.

"More prick, Aunt Linda!" Sherry gasped, squealing with delight as the brunette ground another spiked inch into her frantically sucking cunt. She sank her teeth into Linda's soft shoulder when her aunt sent a fifteen-second jolt of thrilling current through the girl's eagerly gorged cunt. In a fever of lust the lovely naked blonde bit and sucked her aunt's hot tits, then her lips and tongue, then her ears and throat. Sherry didn't know which excited her more – her beautiful aunt's squirming silken curves crushed to hers, or the maddening spiked cock grinding deep and hot in her thrilled cunt.

"Love to fuck you, darling," Linda panted in Sherry's ear, her hands squeezing the blonde's burning tits. "Love your hot tits and pussy – Love you. Sherry!"

The more aroused Linda became, the hotter and juicier her writhing pussy slamming back on her nephew's fleshy rod became. Then Sherry's hands reached around behind the lunging brunette's ass. Her fingers found her brother's swollen balls and Sherry squeezed urgently, while her other hand gripped the base of his boiling meat and began jerking it into Linda's slippery pussy.

"Ah, I'm getting my rocks off!" Jack groaned. Between his aunt's fiery cunt and his sister's lustfully squeezing fingers, his hot load was starting to explode.
