Supergirl flipped through the mail as she entered her flat. There were several cards of admiration from her fans, she smiled as tossed the letters from men offering to marry her, and finally there was this invitation. She looked it over, it was from a science institute. Supergirl opened the letter, and began reading it. It was from a Dr. Von Straus at the Alternate Power Research Institute. He was inviting Supergirl to take part in a new experiment, one that he thought they could find a new and exciting source of power from her. He explained that he had invented a belt that would draw from her expended power, it was a new way that he thought could become very important in the future.
“What is this some kind of joke.” Supergirl frowned as she tossed the letter in the trash, heading for a hot bath.
The next night she again landed on the balcony of her apartment. She tossed the mail to the side as something caught her attention in the stack. It was another letter from Dr. Von Straus. She picked up the curious letter and opened it.
“What?” She read the letter confused.
It was a thank you note. Dr. Von Straus was thanking her for a successful experiment. ...’ We were delighted to have met you and are even more encouraged with the astounding results. As I have stated before, our next meeting is tomorrow at 5 pm. We look forward to an even more productive experiment….’
“What’s he talking about? I wasn’t there.” Supergirl looked over the letter again. That night her mind continued to wonder about the strange letter, how could they have done it without her. Finally she made up her mind to investigate, she would show up at the meeting tomorrow and see what this was all about.
The next day Supergirl went to the address on the invitation. There were several scientist wondering around, many of them stopped and stared at Supergirl as she entered. She had no idea why they were all looking at her.
“Supergirl?” One of them approached her. “What are you doing here? I thought you were already in the experiment? You’re supposed to be in room 7, you’d better hurry.”
“Room 7….um right.” Supergirl played along, she wanted to find out what was going on. “lead the way ok.”
The scientist led her into the experiment site. All of the men inside suddenly stopped, there mouths fell open at the site of her.
“What’s going on here? Who are you?” One of the men asked.
“I’m…” Supergirl was about to introduce herself when she saw her. Another girl, dressed in her costume. She looked exactly like Supergirl, she was the same size, her hair was done exactly like Supergirl’s, and she was also very pretty. The girl was already tied to a chair in the center of the room as others hover over her, making sure she was ready for the experiment.
“I don’t have time for jokes, we are about to begin.” The man said quickly.
“Wait, she’s not Supergirl….I am. That girl is a fake!”
“What’s going on here?” Another of the men walked over. Supergirl saw his badge, this was Dr. Von Straus.
“Dr. Von Straus, that girl is not the real Supergirl.”
“And you are?” He looked her over, both girls costumes looked the same. ”I don’t have any time to argue, if you are the real Supergirl, then come and prove it. I have one more chair and some spare equipment. Only the real Supergirl will generate power. That is the only way you can prove this to us.”
“Fine, I’ll show you!” Without thinking Supergirl quickly took a seat at the second strange looking chair. Several of the helpers came over and began tying her into it. Her wrist were tied at her sides, her ankles as well were strapped to the chair. She pulled at the restraints, they had her bound tightly.
‘But I’m Supergirl….I could break these easily…’ She allowed them to tie her.
The men scrambled back, flipping several switches as she glanced over at the fake girl who smirked confidently back at her.
‘Now I’ll show them who is real.’ She thought smugly.
The experiment was about to start; Supergirl sat in the chair as the belt around her began to hum. Suddenly, something appeared from the chair. It was on her seat, underneath her skirt!
“Gasp!” She was caught off guard as the thing sprayed a slick liquid on her thighs, making them wet and slick. She felt her legs soaked in the liquid, it was smooth and greasy like oil, she cold feel her panties wet from it.
‘What’s that for?’ she thought now felling a little puzzled. She had jumped into the experiment so fast that she didn’t really know what was going on. Without giving her too much time to re-think her decision four robotic arms sprang from the chair. They grabbed her skirt, lifting it to reveal her soaked panties. The other arms took hold of her petite red satin super panties, cutting the waistband, then pulling them free of her. She watched awestruck as her panties were being stripped away by the machine.
“…..!” The shocked Princess of Power was about to shout but she looked over at the fake girl who was sitting quietly looking as relaxed as before. She closed her mouth, she didn’t want to look foolish, as she looked back at the smiling girl.
Supergirl felt better as the arms now disappeared back into the chair, dropping her skirt back down covering her naked mound. She sighed in relief….but something felt funny. She could feel something cold, an opening in the chair, right below her freshly wet mound.
“Ooohhhhmmmm…” A large steel dildo slid up through the hole and into her hot mound. Supergirl’s body tensed as it parted her pussy lips, moving easily on the slick oil, it slid into her pussy meat.
‘Oh...mmm… this is crazy! I cant allow this…mmm…oohh…there must be a better way to prove myself...mmmm….’ The superheroine squirmed in her seat, she began pulling at the belts that tied her down. ‘Have to break free, stop this.’
“zzzzzzz”
Supergirl gasped, her eyes wide.
“zzzzzzz..” the dildo buzzed, pulsing and vibrating inside her pussy. Her breath became heavy, her heart raced as she felt a surge of stimulation. She could feel her passions rising, her pussy becoming hotter, tingling with excitement each time the steel cock pulsed again and again.
“Oohhhh…mmmmm…OOOOoooHHHHH….” It teased her unmercifully, pulsing then stopping, then again, tingling her sisitive walls. She could feel her wetness growing, her body pushing for release.
The scientist suddenly looked up as Supergirl moaned. They looked at one another strangely.
‘Um…h-have…oooHHHH…” the dildo sent shivers through her. “have to g-get freee…mmmm…” Supergirl tugged at her restraints, each time she couldn’t concentrate her power. She was helplessly at its mercy.
“zzzzzzz”
“OOHhhhhhhh…” Her back arched as the device now began sliding in and out of her, buzzing with tiny vibrations as it enter her at will. Supergirl pulled at the belts holding her, but she wasn’t going anywhere as the steel cock began pounding her. Her mouth making an ‘O’ shape as it slipped inside her over and over.
“Ohhhh…OOOHHH….Oohhhhmmmmm….” She squirmed under its control, her nipples becoming hard as they perked up beneath her satin top.
The men looked at her again, whispering among themselves and pointing at the struggling heroine.
“Oh gawd…mmmmm…nnn-noo…” She squirmed even more as now the dildo began to spin, still pounding in and out of her. Warm liquid flowed from the steel dildo, pouring out onto her helpless pussy, making her wetter as it spun and sloshed in her juices. She knew right away that it was no ordinary fluid, she immediately began feeling hotter… making her more horny, the liquid was arousing her, forcing her to even more pleasure. Her body was hot, tingling all over, she tried again to break free, struggling, but the leather straps held her firm as the steel dildo continued to fuck her. She was trembling, she could barely take anymore. “mmmm…” She bit her lip, looking over to the fake. The girl was just sitting there, calm and cool. Supergirl couldn’t believe her eyes. The girl looked over and smiled.
“How you doing over there?” The fake asked pleasantly. She wasn’t struggling or squirming as Supergirl was, she was totally relaxed.
Supergirl turn back to the scientist, her body was wet with sweat, the dildo in her mound beneath her skirt was still spinning, as it slipped in and out of her, sliding easily on the liquid that oozed from her pussy. She was feeling weak, her body was building to a climax, she gasped for air, moaning and crying as the cock slid in and out of her. She couldn’t take anymore when suddenly another compartment opened beneath her. Another of the long smooth dildo’s appeared.
“Gasp!” Her eyes grew wide she felt this one moving closer to her ass. She could feel a slick smooth gel on the tip of it as it also began to spin and vibrate.
“Oh God…mmmmmnnnggggg” She grimaced as the dildo slipped under her panties and penetrated her ass, filling another of her holes.
The scientist looked at her again strangely.
“She seems to be masturbating.” One of them whispered.
“That’s outrageous.” Another looked at her weird.
“Please…P-lease…mmm…st-stop…” She begged squirming in her chair. The hot juices from the device were running down her legs, covering them in a slick shiny coat. She was completely wet, hot and on the verge of surrendering her own climax, she didn’t know how much more she could take as the machine had its way with her body. The experiment continued, tears fell down Supergirl’s face as the machine ravaged her pussy for more than half an hour she felt as if she were going crazy! She trembled, squirming, bound to the chair, unable to escape, she endured the thrusting dildo in her pussy, its hot liquid soaking her, all hidden under the cover of her miniskirt.
“Ha, ha, ha, ha, “ She heard the fake laughing at her, the girl was in complete control…it was nothing to her. Then something unexpected happened.
“Wha?”
The fake had taken her skirt and lifted it to show Supergirl…there was no dildo in her, she only sat there pleasantly, laughing at the fucked heroine. The fake turned back to the men, flipping her hair and smiled back at the men.
‘No…it’s a trap!’ Supergirl thought as she tried again to pull at the straps binding her to the chair, but she couldn’t. Each time she tried the dildo parted her lips again, twirling and spinning inside her, pounding away at her helpless clit. She struggled madly, yelling and crying, hating herself for being so stupid...but it was too late, she was captured.
“Well I guess we know who the real Supergirl is.” The fake laughed at the weak Princess of Power as many of the assistants untied her from the machine.
The dildos pulled themselves from the feeble superheroine, again disappearing into the chair, leaving her wet and messy.
The fake and the scientist walked over to Supergirl.
“You bitch! How dare you insult Supergirl.”
“N-no…I’m the real S-Supergirl..”
“I don’t think so.” One of the scientist opened a folder. “according to these readings, we got all the power from her!” He pointed at the fake to Supergirl’s shame.
“W-What? That’s impossible.” She struggled still strapped to the chair as the men looked down upon her.
“That’s great Supergirl.” The men turned towards the fake. “I cant wait to promote this idea, you’ll be adored by the entire world.”
“Wow, that’s great.” The fake, looking terrific, flipped her hair and smiled as one of them snapped her picture. “But what will we do with her?”
“Maybe we should teach her a lesson.” The same scientist that read the results winked at Supergirl. “Why don’t you take care of her Supergirl…..while we plan your press conference to announce the discovery.”
“What...no…let me go…ouch!.” The fake grabbed her by her hair.
“You’re not going anywhere,” The fake took control of her. “Everybody out, I’ll take care of her.”
The men hurried out of the room as the fake laughed in Supergirl’s face.
“Haha, how you like that you fucking cunt. Now I’m Supergirl. Haha.”
“You wont get away with this…Owwww!!!”
The fake slapped Supergirl.
“Shut up cunt!” she undid the straps that held Supergirl to the chair and threw her roughly to the ground.
“Ohh…” the weak superheroine looked up at the girl as she reached inside the chair that Supergirl had been sitting and withdrew one of the dildo’s.
“It looked like you were having such a good time Supergirl, “ the fake also took a leather strap from the machine and snapped the cock onto the strap. “all I could think about was fucking you.”
“You’re crazy!” Supergirl tried to get up but the fake was already on top of her. She pinned the heroine’s wrist to the floor easily.
“OOOWWWW..”
“Stop struggling slut.” The fake mounted Supergirl with the dildo strapped on her like a dick. “You’re getting fucked and that’s all there is to it.”
“No…you cant do this to me…I’m Supergir…ooohhh”
The fake slapped her again.
“SHUT UP, SLUT.” She roughly pushed Supergirl’s legs apart, spreading her wide, taking the dildo in her hand.
‘No…not going to let her do this to me!’ the superheroine began to fight, trying to throw the other Supergirl off of her.
She slapped Supergirl’s tits this time. She slapped them hard again and again.
“Ow…Owww…..”
“Stop struggling.” She slapped her tits again.
“Ohhhhh….” The heroine wimpered as the fake went to work on her.
The fake lifted her hand dominantly over Supergirl threatening another slap. The mighty Supergirl whimpered beneath her, she had had enough. Tears welled in her eyes as she openly cried.
“Sob.”
“I said shut up, Bitch.” The fake mocked her as she lifted Supergirl’s ankles on her shoulders and pushed the dildo into the sobbing superheroine.
“OOHHHH…..OOOOHHHHHHH!!!!!!” Supergirl cried as the dildo penetrated her juicy mound. It vibrated and spun as the hot juices again poured from it onto her equally hot pussy. The fake began pumping her, her body moving and gliding against Supergirl’s, slamming the dick into her. The sobbing superheroine’s body shook as the girl drove the cock into her hard.
Supergirl lay crying, her hands pinned by the other Supergirl who was raping her. A rush of shame came over her as she could hardly believe she was being fucked by another woman, a pretty woman in her costume….beaten by her and now being used as her sexual toy. The mighty Supergirl cried as the dildo went deep into her, setting her body on fire as sweat dripped all over her. Her tits bounced rapidly as the girl fucked her over and over.
“OOOOOOHHhh..AAAAhhhhhhhhhhhmmmm…..”
The girl fucked her like a man, spreading her legs, her flimsy skirt falling on her stomach as the fake Supergirl slid the vibrator in and out of her over and over.
“How you like that Supergirl,” She slammed hard against the heroine’s mound.
“AAAAAAHhhhhhhhh….” Sweat poured on the heroine, her body hot and toddling on the verge of orgasm.
“You so stupid! Me and the Professor set this trap for you and you played right into our hands, haha.” The girl leaned in close to Supergirl. She still had the heroine’s arms pinned above her head as the dildo vibrated in her clit, she grinded it on the heroine, making her feel it deep. The girl got very close, right in her face.
“You’re finished sweetheart. I’m Supergirl now.” Her soft lips were right on top of Supergirl’s. The heroine could smell her sweet perfume, feel her soft tits in the satin costume against her own. “…and you’re nothing!”
“mmmfffffffff!!!!!!!!!”
The girl kissed her deep, pinning Supergirl to the floor as the dildo forced a screaming orgasm from the heroine at the same moment. Supergirl struggled, unable to throw the girl off, much to weak, she surrendered her juices. Her mound wet and soaked.
The girl giggled, pulling the dick from the frail heroine at her feet. She pumped the fake cock and a spree of white cum covered Supergirl. The sticky liquid covered her panties and costume.
“Hahahahahaha.” The girl delighted.
Supergirl looked at herself covered in the cum. Suddenly smoke began to come from her costume, the liquid was eating through her costume. The liquid dissolved large chunks of her costume, her tits were now peaking through, large and small holes were eaten all around her. Her panties were almost gone as her neatly trimmed pubic hair was exposed. Supergirl could only lie there as the cum exposed her sweaty body.
“Oh, here they come!” The fake quickly undid the dildo from her and slid it through the holes in Supergirl’s panties. She then grabbed one of the semi conscious superheroine’s hands and placed it on the dildo.
“What’s going on here?!” The scientist mouth dropped open as he saw Supergirl lying below him.
“She went crazy!” the fake explained. “started on herself with that thing.”
The men looked a the large cock in Supergirl’s hand.
“Disgracefull!” one of them sneered.
“Supergirl, lets go. There is someone here from the power company ready to pay you millions for the research.” The scientist escorted her away.
“As for her.” He motioned to Supergirl. “get rid of her, out the back!”
Two of the assistants grabbed the slumping Supergirl and carried her through the back door. They placed her half naked self into the back of a car and drove off.
The men each had their turn on her until they arrived at the back alley of a night club. There they threw the superheroine from the car into a pile of garbage. The heroine moaned, beaten and weak.
Supergirl, the mightiest woman on earth lay humiliated in the garbage…..
