"Faster! Harder! Faster! Harder! Harder! Harder!" Jones shouted angrily.
Caitlin punched with her other fist, then with the first, then the second, punching harder and faster and straighter as some of her body began to sort itself out from the violent electrical firestorm that had ripped through it.
Jessie screamed in agony as her tits flopped and jerked and bounced under the continuous blows of her sister's two fists. The two heavy mammaries swung and bounced as Caitlin's fists sunk into their soft meat and sent them hurling backwards like punching bags.
Caitlin had never used speed bags, or even really seen them but she was using Jessie's tits like twin speed bags now as she rattled her fists against the bouncing flesh again and again. Jones laughed in amusement as he watched.
"Enough," he said, twirling the blonde around by her hair and shoving her down to her knees. She bent her over, mashing her face against the floor as he picked up something from the bed. He tossed it to Caitlin and ordered her to put it on.
Caitlin wasn't even sure what it was at first. Her thinking processes weren't working all that well. Still, she slipped it on, realizing quickly what its purpose was. It was a dildo, only it strapped around her hips and nestled down between her legs like a man's penis. She knew it was for fucking her sister with.
"All right, whore, give this blonde slut a real ride," he grinned. "Stick it up her snatch and fuck the bitch till she cums."
Jessie was oblivious to what was being said or done behind her. She sobbed in pain, wanting to fondle her aching titties, which were throbbing with agony as they lay pressed against the floor beneath her. She felt something hard pressing against her cunt, but the sensation was trifling next to the agony of her tits and she practically ignored it.
The dildo was very long, however and quite thick too. It slid remorselessly into Jessie's tight, snug cunt sheath, Caitlin having no choice, or thought of doing other than burying it in the slender blonde's cunt box. She wiggled her hips from side to side when the dildo met resistance, screwing the thick rubber prong around inside Jessie's snatch, humping back and forth until it pushed deeper.
She grunted with the effort, her hands on her sister's hips as she drove the dildo steadily deeper into her cunt chamber. Only when her own hips were pressed hard against Jessie's soft round buttocks did she began to draw back.
She fucked into Jessie's cunt cleft with a steady humping motion, going fast because she knew Jones wanted her to. Jessie hardly seemed to notice at first. She moaned, as she'd been doing for some time but did not try to resist or move away.
"Harder!" Jones ordered.
The order wasn't unexpected and Caitlin immediately began to fuck harder, drilling the thick rubber cock back and forth inside Jessie's fuck tunnel. Her hips began to slap against Jessie's ass flesh with greater force and noise now and Jessie grunted with the impact of the dildo against her fuck box.
"Ungh! Ungh! Ungh! Ungh!" she groaned in accompaniment to the slapping of Caitlin's flesh against her buttocks.
"I think she needs something else to turn her on," Jones commented.
"Take out the dildo and take this." He handed her the cattle prod.
She almost dropped it, staring wide-eyed at the metal tube. Jones undid Jessie's collar and unclipped her wrists from the chain. The blonde groaned in relief as she let her still bound wrists slide down her back. Jones immediately slid a slender chain noose over the blonde's head and down around her throat, then gave the other end of the chain to Caitlin.
"Now whore, you're gonna ride this bitch like she's fuckin' buckin' bronco. And she will be too. Stick that prod as deep in her cunt as it'll go, then hang onto the chain and press the button."
Caitlin thought, briefly, about using the prod on him, but was sure he was prepared for such a thing and doubted she'd be able to reach him before he knocked it out of her hand. Anyway, she was too frightened. She eased the tube into her sister's cunt, reluctantly pushing it deep into her snatch until she could get it no further.
"When I say, you press the button and if she gets away from you before I say to stop I'll shove it up your cunt and show you how easy it is to hold a whore in place and ride her with the prod."
Caitlin nodded her head quickly, gasping in fear at the thought. She pulled the chain tight, not thinking or caring that it tightened around Jessie's slim throat.
"Now!" Jones shouted. Caitlin yelped in fear, her finger pressing down on the button.
Jessie howled in agony, her body pulling desperately against the chain as she tried to tear herself free from the horrible pain ripping through her guts. Her knees smashed and ground against the carpet as her body shook violently, thrashing and pulling, even as the chain choked the breath out of her.
Her head whipped back and forth and her body trembled and shook. She tried to rise several times only to be forced back by Caitlin, who jammed the prod down hard against the back wall of her cunt tunnel. She shook and bucked like a horse, her upper body flying upwards off the floor and back against Caitlin.
Terrified that she'd get loose and Jones would subject her to the prod, Caitlin hung on for dear life, pulling down hard on the chain as Jessie tried to rise to her feet, holding the prod inside her thrashing, shaking, squirming, writhing sister's honey pot as Jessie howled and screamed in tortured agony.
Finally, the breath choked out of her, Jessie fell forward, flat on her belly. Caitlin still knelt between her spread legs, holding the prod down against her snatch as the blonde bounced and shook and trembled on the floor, grunting and gurgling like an epileptic having a fit.
"Enough," Jones said lazily, grinning.
Caitlin turned off the juice and slid the prod out of Jessie's cunt, letting go of the chain. She whimpered herself as she looked down at her sister, still trembling and gurgling and shaking.
"I bet she won't forget that soon," Jones laughed. "Okay, slut, turn her over and start eating that pussy."
Caitlin rolled her sister over, spreading her legs further as she knelt and pressed her face into her bald, burned up little cunt. She tongued her slit, sliding her moist pink tongue up and down the dry cleft, then pushing it inside.
Jessie seemed oblivious to what she was doing. She was still shaking and grunting and Caitlin had to hold her thighs down to keep her gash in place. She pushed her tongue deep into the hole, hoping to moisten some of the fried cunt she had abused.
Her tongue slurped and sucked and slid up and down the blonde's honey pot, probing inside her fuck hole as she sucked cunt. In a determined effort to relieve some of the pain, Caitlin began to rub and suck on Jessie's clitty, her tongue stroking over it again and again.
Jessie's mind was a bedraggled mess, fractured into a thousand pieces by the terrible pain she had undergone. Her body though, reacted as it was made to. On automatic pilot, without the guilt, fear, or anger to effect it, her clit began to buzz with pleasure from the careful stroking of the other woman's tongue.
Caitlin sucked two of her fingers, moistening them, then slid them up into Jessie's snatch, pumping them slowly in and out as she continued to lick and suck on her sister's clitty. She felt Jessie's own lubrication beginning to seep out from her pussy walls and said a small prayer of thanks.
Jessie was still trembling, though not as violently. Her grunts and groans had been replaced by delirious mutterings and whispers, words neither of the others could make out. Caitlin sucked hard on her clitty as she stroked her fingers in and out of the cunt hole she herself had so abused.
Jessie showed no reaction, but her body was obviously responding and that was what Caitlin wanted. She slid one hand up Jessie's body and squeezed a fat tit, kneading the flesh repeatedly as she searched for, then found the hard little nipple.
