"All right by me if it's all right by Auntie Pru. What do you think?" he said, turning to face her.
Prudence licked her lips and said, "Of course, dear child. It will only heighten the experience."
Justin pulled off his jeans and shorts quickly, but Chelsea took a little longer to take her clothes off. They piled their clothes in an empty corner, and returned to their places. "Are you ready now? Then come over to the crosses and let's get you strapped in."
Justine and Prudence walked over and put their hands in the straps of the crosses. It took a few moments to bind their wrists; due to the nature of the event, their legs weren't strapped in. Justin looked up and said, "Aunt Adele, do you have the stopwatch ready?"
"Yes, sonny, I've been waiting forever. Get at those tits," rasped in his ear.
Justin winked at Chelsea; the contestants continued their stare down as Justin fiddled with a lighter. He approached them wearing rough gloves with two large, fat, red scented candles and waited as the wax began to pool. Going behind Justine, he reached around from behind and dripped two drops on each breast from a few inches above. A sharp intake of air greeted him. Prudence sighed with the wax first touched her from the height. Going back and forth, Justin dripped the wax from closer and closer distances, careful to hit new skin every time. After all four breasts were covered in wax, he put the candles down and roughly brushed the wax off with his gloves. Justine and Prudence both yowled at the abrasive treatment of their sensitized skin. The he brought the candles over for another round, pouring huge dollops on each breast from close range, covering them again and rubbing them off. At the third course landed on her left breast, Justine suddenly cried out, "Airplane, airplane, you bastard."
Justin smiled wryly and said, "You're older than me, sis. You're probably the bastard in the family. Now let's see how Auntie Pru handles another round." He poured another two dollops of wax on her breasts; she winced but between a look of bliss filled her face as he poured the rest of the wax on her tits from point blank range. Prudence gasped and relished the sensation. Putting the candles back, he roughly scrubbed the wax off with his gloves again. Justine whimpered and screamed; Prudence smiled warmly and sighed with every touch.
Justin returned with clothespins linked by long strings. "The Zipper trial is next. I will peg the skin of your breasts alternating between you. Two zippers, one from each, will be pulled off at the same time. Pru is first." Methodically, he went back and forth between the two facing women, pinching up the skin and applying the joined pins, which were wooden and smooth. There were two sets that were connected so that they would come off both contestants at the same time with the same pull. Both women took the placement of the pegs, which spiraled around from the nipple to the swelling of the breast from the body, gamely; Prudence seemed to wince a little more as each pin bit her flesh. "Any concessions yet?" Two women shook their heads. "Then off with the first set." Justin pulled sharply like a maniac, snapping the clothespins off Prudence's left breast and Justine's right breast sounded like an angry ratchet lasting almost a minute. Prudence pulled up one knee and said, "Texas." Justin looked in surprise, then cut the cord binding the other two zippers so they could be pulled independently. "All right Justine, are you ready?" She bobbed her head and gritted her teeth.
Another sharp yank and the raucous music did its work to Justine's left breast. She howled in pain and stamped her feet but did not give in. Justin awarded that round to Justine and motioned Chelsea to remove the pegs from Prudence's right breast more gently. Chelsea stroked Prudence's face as she did her work, and whispered in her ear. "You can still do it. Don't worry." Prudence smiled at Chelsea and batted her eyes.
Justin re-entered the room and beckoned the contestants to rise. Without a word, he guided them to the crosses and put their wrists and ankles back into cuffs. Reaching under the table cover, he produced a familiar item: his mother's custom tit flogger. Without preamble, he began hitting their breasts equally with sharp slaps, quickly reddening them more. Then he hauled each breast up roughly by a vise tight grip and gave each underside two stinging blows before moving on. He grinned manically as we went about his work, and laughed to hear both women howl in pain. Three rounds of this and Prudence said her safe word. Justin looked puzzled, then gave his sister another set of five strokes on the underside of each breast.
"You bastard, that's too much," she brayed.
Justin glared at her. "Are you quitting the match?"
She backed down. "No, but stay within the rules we agreed on."
Adele crackled in his ear, "She's a whiny little pussy, but she's right. You're going to dish out some more pain, so save the irritation." Justin looked at Chelsea, who meekly nodded in agreement.
"If you'll step over to the sawhorses, ladies. Please sit on them; your hands will be tied above your head and your ankles will be tied under you. This will be a two stage suction challenge: first, your nipples will be sucked as far as they can go into vacuum cylinders, then your entire breasts will be placed in sucking churns where you'll go as long as you can stand it. Are you getting a good angle, Chelsea?"
Chelsea nodded. Her eyes were already big at seeing her two lovers abused breasts reddened; the color was returning to them, but she was sure after the next round they would have to take a rest. Her thighs were incredibly damp, and she could see that Justin's ten inch rod was at half staff. He gestured for her to help him; she held the tubes free from one another as he situated the four automatic suckers on the nipples. Finishing, he gestured for her to turn the machine on. "How does that feel?" She whispered to him.
Adele's voice crackled over the earpiece. "It's heaven baby, just heaven. Been using them for years. About ten minutes ecstacy, then it gets excruciating; too much of a good thing. You can bring that machine up here when those tarts are done with it."
Justin nodded his head and whispered to Chelsea. "Some women like it and some don't. It's similar to automatic milking machines for lactating mothers, but the sensations are different if there's nothing coming out. I can let you try a set after they're done."
"Looks like you could use one a little lower, beefcake," Adele said. "I'm going nuts up here watching my favorite thing so near and so far away. Chelsea honey, you'd better do something for him soon before he gets blue balls."
Chelsea blushed and whispered in his ear, "I will be ready for something soon as well; I'm leaving a wet trail on the floor. They'll need a break soon."
Justin whispered back, "I have it all planned. Just wait a little longer." He reached out to the controls: it was a variable speed machine and the two contestants sighed as the machine pulled harder. They struggled against their bonds; two minutes into the treatment Prudence cried out, writhed round and shook. "There's an orgasm." Aunt Adele shouted, "I knew you had it in you, Prudy." Another minute later Justine was twitching and moaning, heaving her torso up and down as she reached her first orgasm. Finally, it was clear that the nubs had been stretched as far as possible; shutting it down, he found that Justine's and Prudence's nipples had been stretched obscenely for the same length.
He took the larger vessels and placed them over the entire breasts of both women. Adele was amazed: "Prudence's are the largest ones I've ever seen. Did you have to custom order those?"
He looked at the camera and nodded. "This is going to be fun," she giggled.
The machine was turned on again, and the entire breasts of the two women were pulled forward. They pressed against the clear plastic churns and the women started rolling their heads around while guttural moans escaped their mouth. Justin said to Chelsea: "Put the camera tripod, then bend over and put your hands on the sawhorses in front of them." She was bewildered by his request: slowly and tentatively she set up the tripod and then returned to put her quivering hands on the ends of the facing sawhorses. Prudence and Justine were staring at her amazed as her hands touched the wood before them as their breasts being drawn relentlessly out. He reached around and started pawing her, pulling her nipples and massaging her huge breasts. She gasped at the sensations spreading through her body from her nipples. He gently maneuvered her legs a little father apart, then penetrated her dripping cunt easily with one full thrust of his ten inch cock. The machines whirred, and Justin increased his speed to match theirs; the sweat flying from his body onto hers and hers falling freely on the floor. Justine and Prudence rocked back and forth as they watched, licking their lips while their tit suckers pulled, their eyes glazed maniacally.
"Hey, stupid," Adele yelled, "You're not wearing protection! Do you know where this woman has been?" He nodded his head, rapt in the feel of his cock in Chelsea's tight vagina and still working her breasts eargerly. "Is she ovulating? Are you ready to start making inbred rug rats yet?" But he paid his great aunt no attention as he bucked and pumped, his great cock almost coming completely out of her as he frantically sought his release, on his way to a monster orgasm that was met full force by his partner's, his semen blasting their merry way down his cousin's orifice and their sweat making the floor beneath them slick as it combined with the drippings. Chelsea's expression was lost in the sensations and she screamed at the top of her lungs as her climax hit her. They spasmed together for an eternity before they cooled off, the vacuum churns relentlessly pulling at their targets.
