Mark Carver - Auntie in the middle

"Ease up on her for a minute," Jack said from the doorway. In her delirious excitement, Linda barely heard him, but Sherry eased out the immense prick and sat up between her aunt's soaked, trembling thighs.

"Hell, I thought you'd be back a half hour ago," Sherry told her brother. "Look at the stuff she brought back from San Francisco! Wild, huh?"

"Jesus," Jack muttered in disbelief as he stared at the colossal prick strapped on to his sister. "You fucked her with that?"

"Don't worry, brother, she loves it! All she wants to do is be tied down and fucked and sucked to death."

Jack held up the shiny black whip. "What about this?"

His naked sister shrugged, all the while absently fondling Linda's helpless throbbing cunt with her teasing fingers, licking the juice off them with obscene laps of her tongue. "I don't know. I guess she dip that kind of thing or she wouldn't have bought it. Want in on the action, brother?"

The sight of the two women together – his own sister, naked and lewdly panting, and his lusciously curved aunt, still squirming and sobbing beneath her bonds – had triggered an enormous hard-on in Jack the moment he'd opened the bedroom door. But it was his sister that surprised him more than his aunt. Sherry hadn't just been fucking the helplessly screaming brunette – she'd been practically teasing her to death.

And in spite of the tortured look on Aunt Linda's face, Jack had a suspicion she loved it, even craved this kind of bizarre action. As he talked he stripped off his clothes.

"Okay, Sis, if that's what she wants, that's what she'll get. Let's turn her over on her belly."

The moaning brunette had listened to her nephew and niece with a horrified fascination. They were talking about her as though she were some sort of chained animal! And yet, the deeply frustrated brunette knew deep, down she did love being helplessly tied down and tortured by these two beautiful kids. She thrilled to the feeling of utter humiliation and helplessness, yearned to be a sex-slave who would be savagely punished when she refused to obey any of their strange whims.

And the naked, panting brunette knew why, too. Because she'd bottled up her healthy normal urges for so long, they were now escaping in a fury of vengeance.

She whimpered as they unlooped the cords from her wrists and ankles. "Don't hurt me," she begged in a whisper, knowing it sounded hollow even to her own ears. "Don't tease me any more, kids, please, I'll give you anything!"

"Turn over," Sherry said in a commanding voice.

Obeying, her aunt turned over on her belly, trying not to think about the whip and the dildo, or the fact that her naked creamy ass was now exposed and vulnerable. Quickly, they re-tied her so that she was spread-eagled face down.

"Fuck me in the ass, nephew," she whispered to Jack, wildly aroused at the prospect of his huge cock ripping deep and powerfully into her helpless, tiny anus. "I'll go down on Sherry while you fuck me in the ass, Jack."

She could bear Sherry whispering something to her brother, and a wild thrill of fear and anticipation surged through Linda's soft flesh. Why were they so cruel when they were young? But that, Linda knew, was at least half the reason she was so excited and fascinated. As they whispered back and forth, the bound brunette felt suspense building up in her loins like a tight knot.

Suddenly something gentle, like a caress, trailed across her naked ass-cheeks and Linda craned her neck to see what it was. Fear made her skin crawl.

Her nephew stood beside the bed, naked with his long prick hard and curved upward. In his right hand was the black whip, its thong toying with her tender, helpless ass. And Sherry still wore the immense dildo!

"Fun and games, huh, Aunt Linda?" Jack grinned down at her. "That's what you bought this weird stuff for, right? Well, that's what you're gonna get, honey. Fun and games. Here's the drill. You're gonna give me a blowjob and it's gonna be the greatest one of your life. Except there's a hitch. You've got exactly two minutes to get my rocks off. Two minutes. After that…"

A wild searing pain suddenly exploded across the teacher's naked ass-cheeks as the whip tore down viciously. Linda screamed softly and shivered from head to toe.

"After that," Jack continued, "well, that's a sample, Aunt Linda. Remember, two minutes."

"But don't worry," Sherry broke in, grinning. "I'm going to give you some inspiration, Aunt Linda."

Jack got on the bed, with his back to the headboard. He slid down so that his gorged meat was directly in front of Linda's wet mouth, with his legs on either side of her ribs. His right hand held the whip, poised behind her back to send shivers of fear through the brunette's helpless, waiting ass.

Meanwhile, her naked niece got into a position which would allow her to fuck Linda and avoid the whip at the same time. Sherry slid her legs under her aunt's thighs and leaned back on her elbows between Linda's legs. The girl inched forward until the head of the strapped-on prick she wore began to rub against the brunette's gently sucking cunt. Sherry was becoming wildly excited at the position, which allowed her to see every detail of Linda's soaked pink pussy as she eased the huge prick in, as well as every detail of Linda's puckered asshole. The blonde could also watch her brother attack the beautiful brunette in the mouth at the same time.

A violent idea suddenly flashed in Sherry's mind. It would be a terrible thing to do to Aunt Linda, of course, but her tiny asshole was so naked and helpless, so inviting in its juicy, puckered way between her huge creamy ass-mounds, a thrill of excitement shuddered through Sherry's loins.

"Everyone ready?" Jack said, glancing at his watch.

"I sure as hell am," Sherry said, switching on the dildo. She inched the knob inside Linda's wet pink pussy walls and instantly the brunette began to make feverish fucking motions on it.

"Yes," Linda whispered, becoming frantically aroused at the bizarre game. God, she loved to be fucked by that vibrating monster! And especially by Sherry, who instinctively knew how to tease and provoke her with it.

"Okay," Jack said, easing the head of his fleshy rod inside his aunt's warm, waiting mouth. "Go!"

Hungrily, Linda began to whip her head back and forth, her lips sucking at her nephew's pounding hard-on with ravenous delight. It didn't seem fair to her that her hands were tied down because she knew she could make Jack came in two minutes if she could jerk his beautiful meat off at the same time. But the challenge brought out the best in the passionate brunette. She whirled her tongue madly around the pulsing head of his hot dick, then rammed as much of his shaft as she could get in her mouth, sucking in a frenzy of both fear and lust. Linda tried desperately not to think about time passing, concentrating only on the delicious hot battering rant of Jack's big prick in her mouth, swelling and growing hotter by the second.

Her frantically sucking pussy was becoming gorged at the same time by Sherry's eager fucking, and wild, shattering waves of pleasure pounded through her crammed cunt as the spikes tingled her cunt-flesh.

Sherry suddenly hit the red button for ten seconds, and Linda screamed low in her throat and sank her teeth sharply into Jack's quivering prick.

"Goddamn!" he grunted and the whip came down, sending bolts of nerve-racking pain through the brunette's trembling ass-cheeks. Instantly, Linda released her teeth and with tears of pain in her eyes sucked faster and more furiously than ever, praying he would shoot off in her mouth.

Sherry was growing hotter with each thrust of the big cock in her aunt's loudly sucking pussy. The blonde began to stroke brutally, driving the dildo in with savage lunges of her hips. With one hand, she reached over and jammed a finger deep into Linda's squirming asshole, and her aunt's silken ass quivered madly with delight.
