"Why are you doing this to me?" she asked, feeling, terribly vulnerable and alone. Once again, she was completely bound and totally at the mercy of others, and her fear was growing by leaps and bounds.
"Because you're going to exercise whether you want to or not," Tara said. "There's a gauge down there in front and, in spite of how much you whine and moan like a bitch dog, you're going to ride this thing the equivalent of five miles!"
When Tara moved back, Sharon glanced down. Sure enough, there was a gauge down beyond her knees. She had ridden exercise bicycles before and she knew that, if they didn't have the resistance set too tight, she could make the five miles with ease.
Tentatively Sharon pushed at the pedals. The tension was set way down, so Sharon knew there would be no problem pedaling five miles. She resolved herself to getting it over with as soon as she could, so she pushed down again with her left foot.
"Oh!" she squeaked when something jamed hard into her pussyslit. It felt like the head of a horribly thick cock. Her feet immediately stopped on the pedals, and she sat there trembling with confusion.
"Get to pedaling, bitch!" Tara hissed up at the frightened secretary.
The other young woman, her bald pussy showing through the open crotch of her leather garment, crossed her arms across her naked tits and smiled a wicked smile.
"But something punched me in my pussy!" Sharon exclaimed. "I don't know what would do that to me!"
"Did we forget to tell you about that?" Tara asked, an evil smile on her face; "Every bit of you needs to be exercised so the bicycle has a built-in dildo to ream out your cunt! We want that little pussy of yours to be real strong so it can squeeze down on a prick or tongue!"
"Oh, no!" Sharon moaned, squeezing her eyes shut. Her cunthole was already bruised and tender, and it didn't need any more beating from a phony cock, she knew that the claim about exercising it was just a way to taunt her.
"Stop being such a frightened little bitch!" Tara snarled at Sharon. "The fucking thing is greased! The bicycle keeps it oiled up as long as you pedal, so it won't tear your pretty little pussy!"
"Yeah," the assistant said. "The dildo for your pussy is just as slippery as the other one that's going to fuck your ass!"
Sharon's eyes popped open in surprise. She stared at the other young woman. But, before there was a chance to sort out the words, Tara grabbed one of Sharon's nipples in each of her hands. Her fingers bit severely into both of the tit-mounds, then her wrists turned to twist savagely on the tits.
"Aaargh!" Sharon cried.
Her tits felt as if they were being ripped from her chest. The pain was so intense that it sent the gripping agony clear up through her shoulders, neck and jaws.
"Pedal, bitch!" Tara hissed. "If you don't, I'm going to tear these naked tits off and stuff them in your mouth, then make you eat them raw!"
It was a choice of terrible pains, but at least Sharon's cunt and asshole wets built for penetration. There was absolutely nothing to relieve the horrible agony now ravaging her tits so reluctantly; her feet began to slowly move.
The aid of the dildo returned from the scat and brutally pushed into her cunt. The cockhead was centered on her tiny cunthole, and the thick prick shoved its way inside. Thankfully, Tara had been telling the truth when she said it was heavily greased. The grease paved the way into her pussy, and it kept the thick shaft from hurting her aching pussy.
After reaching clear to the deep end, the phony prick began sliding out of Sharon's cunthole. When the swollen cockhead dropped back into the seat, turning her pussylips free, a terrible new pressure began centering on her tiny closed asshole.
Sharon could feel the point of the phony cockhead about to rape up her shiner, but there remained the horrible torture of Tara's hands ripping at her tits. Her asshole was no longer virgin, and Sharon knew that it could stretch open for a prick, so, groaning deeply, she continued to turn the pedals while the thick dildo fucked painfully up her ass.
The dildo was long, reaching clear up so her guts before it began to descend, and Sharon gritted her teeth from the sensation of her shithole. Finally, the lewd, cornholing dildo moved out of her guts and back down into the seat, only to be replaced instantly by its cunt-spearing rubber companion.
Sharon's feet moved at an agonizingly slow pace. It would take a long time to ride five miles, but at least it made the cunt-fucking and assrape as gentle as it could be. When Sharon was well into a slow rhythm, Tara released her tortured tits and backed away to stand in front of the exercise bicycle.
"Umph! Umph! Umph!" Sharon grunted as her cunt and asshole were fucked.
"You're going to have to ride faster than that, bitch!" Tara snarled. "We're not going to stand down here all night while you ride a slow five miles."
Sharon tried to make her legs move faster, but each time she did, the fake cocks painfully hammered into her asshole and pussy. The torture was more than she could stand, so she immediately slowed down to a pace less painful, and continued to slowly pedal phony cocks up her cunthole and shitter.
"I guess we're going to have to give her some incentive," Tara said as she watched the tortured young woman. "We can't have a lazy bitch like this ruining our secretarial staff!"
"Can I do it?" the brown-haired, lusty young assistant asked.
She appeared to be so excited that she almost pissed down the insides of her legs.
"Be my guest!" The older woman laughed at her assistant's excitement and moved out of the way.
The younger woman scurried over and stood in front of the bicycle as Sharon continued to slowly pedal. The assistant reached down into a cabinet built in the front of the bicycle's base and extracted two long wires tipped by alligator clips. She held them up toward Sharon's naked tits, opening the sharp metal teeth.
"Noooo," the bound, naked secretary said when she opened her eyes.
Horrified, she watched the clips being snapped onto her nipples, then the biting pain caused her to scream is it felt like the tips of her tits were being eaten. Her feet jerked to a halt on the pedals, leaving one long dildo crammed tightly up her distended whole as she trembling agony until her tits started to go numb. "You know what's coining next don't you, you sweet little sex slut?" Tara asked as she pushed the assistant out of the way and moved back in front of Sharon. "I'm going to count to three, then I'm going to turn the current on full blast and leave it that way until you've pedaled five miles! If you don't want to fry your tits right there on your chest, you better get to moving those Goddamn feet!"
Tara stepped back.
"One!" she shouted.
Sharon's feet began to push. The muscles of her legs tensed as they bore down on the pedals.
"Two!"
The tortured secretary grunted and pushed harder. The bicycle was picking up speed. The dildos ticked into her cunthole and ass about as fast as a man usually pumps his prick.
"Three!" Tara shouted triumphantly, and leaned down to the cabinet and threw the switch. Immediately, electricity seared into Sharon's tits, burning through her nipples.
"Aaaargh!" the naked secretary screamed through the pain. The current ripped through her flesh and into her chest, where it choked off her air.
Furiously, she drove harder with her feet. She knew it was her only hope to stay alive. The pedals spun, beginning to pickup speed. The current died down at least enough for her to take in a ragged breath. But the pain in her chest was still bad, so she forced her feet to move even faster.
Hard, phony cock hammered violently into her cunthole, slamming against the end of the fuck channel to batter at her already-bruised flesh. Quickly, the thick dildo ripped out of her pussy as the second dildo rammed up her ass. It shocked her guts with its brutal blow, then began to rapidly retreat.
