Batgirl's endurance training (written by Kingnothing1996) (reupoad)

The Batcave.

Hidden beneath Wayne Manor, it was likely one of the most secure locations on Earth. The technology within was some of the most advanced in the world, with only the Justice League’s Watchtower boasting more impressive tech.

Speaking of the Justice League, they were currently off-world. Barbara Gordon, the former Batgirl and current Oracle, wasn’t entirely sure what it was this time. Apparently it had come up rather suddenly, and involved War World. Honestly why the League was off-world wasn’t important to Barbara. What was important was that it meant Bruce was off-world, though Barbara didn’t know how for long. Because of that uncertainty, Barbara had decided she couldn’t wait. There was something she’d been planning for awhile now that she could only do when Bruce was gone.

Over the years, Bruce had disappeared from the cave for extended periods more times than Barbara could count. Sometimes it was only for a day or two, other times he was gone from Gotham for weeks. During those periods, Barbara had done some renovations to the cave. She knew that Bruce knew about them, despite her doing them while he was gone, but that was fine. It was better for Bruce to know and not to say anything than for him to say anything about it. 

What Barbara had done was install a hidden room in the Batcave. It wasn’t overly large, and it was hidden behind a piece of fake cave wall. A retina scanner gave Barbara access to the room, and she smiled as she wheeled her way inside.

The floor, walls, and ceiling of the hidden room were completely and utterly covered in white padding, almost like a cell in Arkham Asylum. The sole furnishing in the room was a metal table that stood in the center of it, low enough that it was level to Barbara’s stomach. 

The table, of course, didn’t interest Barbara. Sure it was a nice table, but Barbara was more interested in who was laying on it. 

A feminine figure laid on the table, covered from head to toe in shiny black rubber. Her arms were forced into a tight self-hug by a straitjacket, and her legs were forced together by a legbinder. Her head was totally covered by a black latex hood, leaving only her nostrils uncovered, and a spherical bulge could be seen where her mouth should be. A pair of black spikes emerged from the hood, resembling the ears of Batman’s cowl, and a yellow Bat-symbol was printed on the chest of straitjacket. Underneath the suit, a pair of dildos had penetrated her, one at her crotch and the other at her ass, and built into the hood were nanomachines to block off the one ways lenses of it and a pair of earplugs that deafened the wearer to the outside world. A vibrator was strapped to her crotch and buzzing away, causing her to squirm around in pleasure. A few chains ran from the table to the straitjacket, ensuring she didn’t end up squirming her way off of it, even though the fall wouldn’t hurt.

At first glance, somebody would have thought this was just some kinky take on Batman or Batgirl’s outfits, worn by some random kinkster. This assumption would be half-right. Yes, this was a kinky take on Batgirl’s outfit, but it was not some random woman underneath the rubber.

No, underneath the rubber, moaning and squirming, was Cassandra Cain, aka Batgirl herself.

This room was what Barbara called the Endurance Room. When she was Batgirl she had used it on herself, and after being paralyzed, she had used it a few times on Spoiler. Now, it was Cass’s turn to have her endurance tested. 

Admittedly, Barbara had lied a bit to get Cass here. She’d told her successor that she wanted to test her endurance while Bruce was gone, but she hadn’t told her how she intended to do that. She suspected that Cass had started getting suspicious when Barbara had presented her with a latex version of her Batsuit, and she knew that Cass had become suspicious when she produced the ball gag. That said, if Cass had had any issue with it, she didn’t voice it, instead kneeling and opening her mouth for the gag. The hood had followed, then the straitjacket, then the dildos, and then finally the legbinder had come after Barbara got Cassandra on the table. 

The last item that Barbara had added was the vibrator, and she had set it to random. In that setting it would cycle through the various settings without any pattern or set time. Cass could experience low edging for twenty minutes before experiencing fifteen seconds of full power. That was where the Endurance Training came from. Barbara had told Cass she could only cum a few times before, not telling her the actual limit, and that if she passed it before time was up then she’d be punished. Of course, Barbara had also failed to mention what the time limit actually was. 

After Barbara had explained all of this to Cass, she had left her alone to squirm and moan. Barbara did have a video camera in the room, allowing her to keep an eye on Cass, and if something did start to go wrong, an alarm would sound and Barbara could release Cass. Hours had passed since then, and the time limit was nearly up. If Cass managed to hold out just a bit longer, she’d pass, but she was dangerously close to reaching the orgasm limit. In fact, all it would take was one more orgasm for her to reach the limit, and once that happened it would be time for Barbara to punish her. 

For a moment Barbara merely watched as Cass squirmed and moaned. She could hear the weak buzzing of the vibrator, telling her it was on its weakest setting. Honestly Barbara could easily have spent hours sitting here, watching Cass struggle. She wondered what it was like for Cass, being bound and forced to cum over and over despite her best efforts not to. Barbara could easily have ended the test now. Cass didn’t know how much time was left, and she doubted the young woman would be focused enough upon her release to tell if Barbara was lying. But, if Barbara did that, then she’d be robbing Cass of a chance to prove herself.

“Decisions decisions,” Barbara said as she watched Cass’s struggles, weighing her options mentally. Ultimately, the former Batgirl opted for the latter option. Wheeling back a little bit, Barbara pulled out her phone and opened an app that controlled the Endurance Room. With the press of a button Barbara got the metal table to lower enough for her to move herself from her wheelchair onto it. Cass seemed to notice the movement, but the vibrations quickly distracted her. 

Pressing another button on the app, Barbara turned on the earplugs that she’d placed in Cass’s ears. While the earplugs were designed to deafen her, they also could send a direct feed of Barbara’s voice and only her voice.

“It’s almost over Cass,” Barbara said as she ran a hand along Cass’s bound body. “All you have to do is hold out against one more orgasm for just a bit longer and you’ll pass the test,” as she spoke, Barbara’s hand stopped at Cass’s chest. Slowly Barbara began to grope Cass’s breasts, eliciting more moans from her.

“I’m sure someone as strong as you can hold out a little bit longer, no matter what,” Barbara said as she repositioned herself, laying on top of Cass as she continued to play with her breasts. A groan escaped from Cass as she felt Barbara laying on top of her and her squirms intensified. She groaned into her gag, trying to tell Barabara to get off, that she could pass if she got off of her.

Barbara had a faint idea of what Cass was trying to say, but honestly she didn’t care. The more she played with Cass’s body the more she wanted to push the young woman to her limit. If she succeeded and managed to keep herself from coming one last time, then she’d be proud of her protege. If she failed and came, then she’d enjoy Cass’s punishment. The redhead began planting small kisses on her latex covered face, focusing on the area around her ball gag. From how Cass’s squirms were intensifying, Barbara could tell that the vibrations and molestation were pushing her closer and closer to her final climax.

“Just a little more Cass,” Barbara whispered. Cass’s moans were growing louder, and she was bucking her hips more than before. Glancing at her phone, Barbara saw that Cass only needed to withstand just a couple more minutes. To give her protege a slight advantage in these final minutes, Barbara switched the vibrator off of the random setting, instead setting it to its weakest possible setting. Even with the hours of edging and orgasms, it shouldn’t have been enough to push Cass over the edge.

Unfortunately, Barbara failed to account for her molestation of Cass. The touching, groping, and kissing of Cass’s body had been the equivalent of the vibrator on its maximum setting.

As Barbara watched the countdown reach thirty seconds, she felt Cass’s squirms reach a new level of intensity and her moans grow louder as she bucked her hips. Under the hood, Cass’s eyes threatened to roll back into her head as she experienced her final and most powerful orgasm of the entire night. It completely destroyed Cass’s sense of what was going on around her, and she didn’t notice Barbara getting off of her. All she was focused on was the pleasure.

Cass did notice the hood being pulled off of her and the ball gag being removed from her mouth, but only because it would be impossible not to notice. She felt Barbara’s hand soothingly running through her hair as she panted. Slowly the young woman’s vision began to unblur as the pleasure faded. Eventually she could see Barbara lying next to her. 

“Sorry…” Cass managed to get out. She already didn’t talk much, and the hours spent moaning into her gag had left her voice slightly hoarse.

“You did your best,” Barbara replied. There was disappointment in her voice, and as Cass turned her head to look at Barbara, she saw it in the subtle movement of her body. Truly Cassandra did feel bad for failing. Even if this “endurance test” hadn’t been what she was expecting, failure stung, especially with the encouragement Barbara had been giving her at the end.

Though now that Cass’s head wasn’t clouded by lust, it did occur to her that Barbara’s encouragement hindered more than it helped…

“I’m sorry Cass, but I really don’t have any choice but to punish you,” Barbara said, her words snapping Cass away from her thoughts. One by one the chains keeping Cass to bed were disconnected, and the vibrator was removed. Cass hoped that her punishment would free her from her rubber restraints, but she wasn’t holding her breath.

Cass watched Barbara get off the table and go back to her chair before having the table raise up. Underneath the table was a cabinet full of equipment, and from that cabinet Barbara retrieved a new latex hood. This hood lacked the lenses and bat ears of the previous hood, further anonymizing Cass. The hood also had a pump gag built in, one shaped like a rubber dildo. 

Slowly the table lowered back down, and Barbara once again hopped onto it. 

“Open,” Barbara said, her tone firm and commanding. Even if it hadn’t been, her body language was, and even then Cass intended to obey her. She had failed, and she was being punished. She had been told that was what would happen, and she had no issue with that. Barbara wasted no time in hooding Cass, covering her head with black rubber. She took a moment to smooth it out before zipping it up, and once she had done that, she began to squeeze the pump. The dildo on the other side had started quite small, but with each pump it gradually grew larger. Barbara could hear Cassandra beginning to make muffled pleas, saying it was too big, but Barbara ignored them as she pumped until she couldn’t. The dildo now filled Cass’s mouth completely, as well as part of her throat, and thankfully it didn’t cut off her airflow.

“Now for the rest,” Barbara said as she went back to her wheelchair and pressed some buttons in the app. Raising her gaze, she watched as the ceiling opened up, revealing a quartet of robotic arms. Two of the arms held nothing in their metallic hands, while the others held an uninflated latex sack. The other two arms grabbed Cass by her shoulders and lifted her into the air. The blind and deaf Batgirl could only squirm and moan as she felt her body rising. She tried to squirm her way out, but the robotic arms unsurprisingly had iron grips. Ultimately there was nothing Cass could do. Now it truly dawned on her how completely and utterly helpless she was. Her years of training meant nothing thanks to the restraints, and the gag kept her from pleading for Barbara to stop.

Speaking of Barbara, the redhead couldn’t help but grin as she watched the robotic arms zip Cass into the sleepsack. Once that was done, they temporarily retreated back into the ceiling, reappearing a moment later with a tube that they promptly connected to the sleepsack. A faint humming could be heard as the sack began to inflate. Cass couldn’t hear it, but she could feel her movement becoming increasingly limited, prompting her to struggle more fiercely in the vain hope that she could break free. Little by little the sack grew larger and larger until it finally reached its maximum capacity. By then Cass’s struggles had ceased, not because she’d realized they were pointless, but because she simply could not move anymore.

“This will be the last time you hear me for a bit, so listen well,” Barbara said to Cass. She hadn’t removed the earplugs, meaning Cass could, for the moment, still hear her. “For your punishment, I’m going to leave you like this. I’m not sure for how long, but it won’t be any longer than a few days. During that time I’ll be leaving you here, bound and gagged, suspended and helpless. There are nanomachines in your suit that will take care of food and waste during this time.”

“Your punishment is to be unable to see, speak, here, or touch anything. You won’t feel anything but the tightness of the rubber around you, and you won’t even have any vibrations to distract you.”

A whimper escaped from Cass in response to this news, making Barbara smile. She didn’t consider herself a sadist, but she couldn’t deny that Cass was cute like this. 

“Don’t worry, I’ll be sure to give you plenty of attention once you’re out, and who knows, maybe I’ll invite Steph to help,” Barbara said. “Until then…” Barbara said, trailing off as she remotely turned off the earplugs, rendering Cass deaf. Now the only sense she truly had access to was smell, and Barbara imagined all she could smell was rubber. Cass whimpered and began struggling again, making pleas into her gag for Barbara to let her out, but those pleas fell on deaf ears. Barbara ignored them as she had the table lower itself down into the ground, where it was quickly covered with more padding. Once that was done, the former Batgirl quietly wheeled her way out of the Endurance Room, leaving Cass to struggle in solitude…

Several months later…

The sound of squeaking filled Gotham’s night air. Once again the cities main defender was absent, off dealing with some interplanetary threat with the rest of the Justice League. In his absence, the Batfamily stepped up to ensure Gotham didn’t fall into chaos as the city's criminal community took advantage of Batman’s absence.

That said, it wasn’t just the criminal element who took advantage of Batman’s absence. For the members of the Batfamily, this was a chance to get away with what Batman would normally disapprove of. For some this meant a more brutal approach to fighting crime, while others “borrowed” some of the gear Batman usually kept to himself.

For Oracle and Batgirl, this was an opportunity to use an “alternative” costume.

Currently, Cassandra Cain was covered from head to toe in shiny black rubber. A black rubber cape was draped around her shoulders, and the only part of her ensemble not made from rubber was her utility belt, and that was solely until Oracle got her hands on a functioning rubber utility belt. 

Under the layer of latex were two items. The first was a ball gag, which was visibly bulging against the latex hood that hugged Cass’s face so tight that the outline of her lips was visible. It rendered Batgirl speechless, but it didn’t really matter considering she was never the most talkative member of the Batfamily. The other item was a metal chastity belt locked around Cass’s crotch. A padlock was visible under the rubber, and the only key rested on a string around Oracle’s neck. Speaking of Oracle, the outfit had been her idea, and she was quite happy to watch Cass running around in it through Gotham’s network of security cameras.  

“Alright Batgirl, time to make your way back to the Batcave. The sun’s coming up, and it’s almost time for your endurance training,” Barbara said as she looked up at the numerous screens of the Batcomputer. She’d taken care to ensure the male members of the Batfamily stayed away from the cave, although she had left the invitation open to Kate and Steph to join.

In fact, both Steph and Kate had accepted that invitation. Typing a few commands into the Batcomputer, Barbara brought up a direct video feed on the Endurance Room. In their, both Steph and Kate were bound and clad in latex parodies of their normal outfits, already having their endurance tested. Kate was sealed inside a transparent crimson vacbed, allowing Barbara to see the expression of lust on her face as the wand sealed in with her buzzing away. Steph was bound to a Saint Andrew’s cross, her arms and legs spread out in an X shape, with a wand at her crotch joined by a pair of smaller vibrators taped to her breasts. A ring gag was strapped into her mouth, forcing her to drool uncontrollably. That drool landed directly on Kate’s breasts, as Barbara had positioned the two in such a way that they could lock gaze.

“Mmph Mnphphrmphph,” Cass responded, immediately beginning to make her way back to the Batcave. Over the past few months, she’d come to love the feeling of rubber, of being restrained, and of being gagged. But most of all, she had come to love the touch of Barbara, and she was eager to feel it again. She didn’t know of what awaited her in the Endurance Room, nor did she know what Barbara had planned for the trio of vigilantes. All she knew was that soon she’d feel the touch of her Mistress again, and that was all she cared about.
