Deep below the Earth's ground was a secret justice league training area which Batgirl and Supergirl entered. Batgirl was dressed in her superhero outfit which was skin tight black leather outfit with matching cowl hiding her upper face with a thin yellow bat symbol over her chest with yellow gloves and boots. Supergirl was wearing a light blue t-shirt with the super man symbol on it and the shirt showed off her belly with a short red cape attached. She also wore a dark blue skirt with red knee high boots.
"I don't understand why I'm here." Supergirl said as they walked towards the center of the training area.
"It's required by the league that everyone have escape training." Batgirl replied as she went to a nearby console and pressed some buttons which made a small shelf appear out of the ground full of binding materials.
"Hello! I'm Supergirl, no rope can hold me." She ignorantly said.
"We'll see about that." Batgirl said as she tossed her a coil of rope. "But today I'm just schedule for training so get to it." She said placing her hands behind her back.
"With pleasure." Supergirl said with a smile as she began to loop the rope around Batgirl's wrists.
"Just be careful not to pull it to tight, I still need my hands." Batgirl said as she could feel the rope being pulled tightly against her gloved skin.
"I know what I'm doing." Supergirl snapped at her as she had her wrists bound and was now binding her elbows and lead the rope around her beasts going above and below them making them push out against her leather suit.
"Your not bad." Batgirl commented as she could feel the tightness of the rope around her chest.
"Thanks." Supergirl said as she moved down and began to bind Batgirl's knees and then her ankles.
"Alright, that should do it. Now if I can-" Batgirl began to say before she was pushed to the ground on her chest. "Hey! What are you doing?" She asked as she looked behind to see Supergirl giving her a evil grin as she held a coil of rope.
"Oh, were not done just yet." She said as she as she looped one end of the rope through her wrist bonds and looped the other end through her ankle bonds and pulled at the rope tightly till Batgirl's back was arched all the way. This left her in a hogtie that allowed her fingers to touch the tip of her boots.
"Ahhhh, this is, too much!" Batgirl gasped out as there was no slack to the binding.
"Your saying I should go easy on you?" Supergirl asked with a laugh. "No villain will go easy on you, heck they might bind you tighter, if possible." She said with a smirk.
"Gahhhunnn, I'll get free of this." Batgirl said taking the challenge as she began to wiggle and struggle on the floor. As she did though she had to work hard to suppress her moans as her tight outfit and the rope was rubbing and tugging at certain parts of her body.
"Note to self, change costume material when I get back." Batgirl mentally noted as she continued to wiggle and rock back and forth on the ground which only made her work up a sweat.
"You know, now would be some good training against the joker's tactics." Supergirl noted as she casually walked up to Batgirl and eyed her boots.
"What, what do you mean?" Batgirl grunted as she rested on her side so she could look at Supergirl.
"I mean this." Supergirl said as she adjusted Batgirl's bindings so she could slip off her boots and then she slipped off her black socks leaving her feet bare and exposed. She then put the rope binding back to like it was.
"What are you doing?" Batgirl fearfully asked as she wiggled her toes.
"This." Supergirl said as she danced her fingers over the soles of Batgirl's feet making her squirm and laugh.
"Hahaha, no, no sssthahahahststop!" Batgirl gasp out as she began to laugh like mad from the tickling. "Plaseeeehshahah, I'm, I'm very hahah ticklish therehahahaha!" She laughed out as she was squirming madly on the floor which only made the rope more tighter making her suit tug harder at her body. This made her start to moan out along with her laughter.
"I always knew those suits were more than for show." She said as she gave Batgirl's crotch area a slightly rub making her moan more before returning to her tickle torture.
"Gahgahga, sssstop!" She pleaded once more.
"You know, your too loud." Supergirl said as she picked up both her socks and shoved them into her mouth and used a cloth from the nearby shelf to hold them in by wrapping it tightly around her mouth.
"Hrhrpmrpmr!" Batigrl moan as she wiggled on the floor more.
"Now where were we?" She asked as she resume to run her fingers up and down Batgirl's feet making her moan and laugh behind her gag as she was helpless to be tickled for a good hour.
"You know, the joker will be even worse than me and your not looking so well." Supergirl pointed out as Batgirl was breathing hard behind her gag and she had tears streaming out from her eyes from laughing so much.
"Hrpm." Batgirl tried to cuss her out behind her gag.
"Well I need a break, don't go to far." Supergirl told her as she stood up and walked to a different part of the base.
"Hhpmmmmmm." Batgirl glared at her as it was time for pay back.
"I brought you some water, I figured you be thirsty." Supergirl said as she came walking in but dropped the bottle out of surprise as she saw ropes and Batgirl's gag scattered about the spot she left her at. "Uh-oh." She said as rope was suddenly looped over her arms several times. "Hey!" Supergirl cried out as she turn around to see Batgirl with a smirk.
"Payback time." She sad as she began to knot off the rope which pinned Supergirl's arms to her body.
"Someone's cowl is too tight to hear, mere ropes won't hold me." She said as she flexed her arms to snap the ropes but instead the ropes did not break and only rubbed against her fair soft skin. "The hell?" Supergirl said as she tried again but the ropes wouldn't break no matter how hard she tried.
"I did say we both had to take escape training, as such special rope was made for you which is woven with tiny amounts of kryptonite. Just enough to weaken you down to human strength and not enough to affect your health." Batgirl explained with a wide smile as Supergirl had a terrified look on her face.
"Hey, that whole tickling thing was training and a joke. I hope you forgive me." Supergirl said as she tried to remain on Batgirl's good side.
"Oh I know, all training. As such I think I should give you some resistance training as well. I hear Darkseid can be very cruel." Batgirl said as she dragged the struggling Supergirl over to the center with all the special rope.
With a little work Batgirl was able to tie Supergirl in a tight strappado binding which she had used some blue rope to bind her elbows together in a cuff style and did the same to with her wrists with a rope extending from it leading up to a hook above her forcing her arms straight out behind her back. She then used a bar with a little kryptonite in it with straps at it's end to keep her legs spread out far and wide and she put a collar around her neck with a special weight that made her lean forward.
"I think this is a bit much!" Supergirl cried out as she felt her arms being pulled from the tie.
"Not at all, it could be worse." Batgirl said as she suddenly gave Super girl a slap on her rear making her yelp.
"What, why did you just do that?" She asked looking behind.
"Payback." Batgirl said with a grin as she rubbed her other butt cheek before giving it a quick slap making Supergirl cry out.
"Stop it!" She pleaded.
"I don't think the enemy would stop because you asked." Batgirl said as she slapped her butt several times which turn them into a rosy pink color. "Besides, your begging for it with this tiny skirt and tiny red thong." She said as her cheeks were visible with her current position. Batgirl gave her another slap with her fingers slightly dancing on her crotch making her moan after her yelp sound.
"Alright, alright. I'm sorry about the tickling. Just stop." Supergirl pleaded.
"Not yet, not till you learn your lesson." She said as Supergirl opened her mouth to ask her to stop but just received a red ball gag instead.
"Nrprmprm!" She moan as she chewed on the hard rubber ball.
"Because the spanking starts now." She said as she grabbed a thick wooden paddle.
"Hrprmpm." Supergirl moan out of fear upon seeing it and then cried out loudly behind her gag as she was hit hard with it on her butt cheeks. "Hmpmr! Hrhprm! Hrpmmmph! Rpmrhrpm! Rmrprmpm! Mpnpn!" She cried out with each hard smack which made her body jiggle and even shot saliva forward from her mouth as she was drooling madly.
"And one more." Batgirl sad as she smacked her again and had to stop as the paddle was starting to break. "Without that kryptonite rope I don't think I could hurt you with this." Batgirl said setting the paddle on the floor.
"Hrprnhrp!" Supergirl moan as her butt felt very sore.
"I doubt you'll be able to sit for a week." Batgirl said as she pulled out a thick metal paddle.
"Rmrprhprmrpmr!" Supergirl shrieked upon seeing it.
"If you don't want to feel this, then promise this is where this whole punishment thing ends here. No getting back at me for this alright?"
"Mrpm! Mrmprm! Mrpmr!" Supergirl nodded her head frantically.
"Good, you don't want to see what worse things I could do." Batgirl said with a playful look as Batgirl helped Supergirl escape from her binding.
