Supergirl was allowed to rest until noon the day after the gang-bang marathon in which all of Catwoman’s henchmen took part. She was still very weak when she was taken to Dr Rancor’s lab.

“How is our Superslut feeling today?” Dr Rancor greeted her cheerfully as she was strapped down.

“F-fine, sir,” the young heroine answered submissively.

“Good! Just perfect for the final part of you training!” Final part? Supergirl was scared but didn’t dare to ask the doctor. As usual, electrodes were attached to her nipples and cunt lips. Normally, an electrode would also be attached to her clit, then Dr Rancor would use electric pulses to stimulate her and check her response. But today, a strange, tube-shaped instrument was attached to her clit. And to Supergirl’s horror, a gag was also put over her mouth. Will this hurt? she wondered in panic.

“Is she ready?” Catwoman asked.

“Yes, just watch this,” Dr Rancor answered. As Supergirl watched in fear, Dr Rancor switched on his instruments. Immediately Supergirl began to feel pulses of pleasure at her nipples and her pussy, but they were all numbed in comparison to the sensation that she was feeling at her clit. It was a sensation of pleasure a thousand times stronger than any sexual pleasure that she had ever experienced, and it was still getting stronger. It was like her clit was expanding and expanding, Supergirl thought. Within seconds she came, and she just kept on coming. Supergirl was almost delirious.

“Mmmmmmmmm!” she screamed under her gag before she blacked out. Supergirl had a strange dream. She dreamt that she had become a man - No, it’s not that, she corrected herself. In her dream she had grown a cock, a cock just like the men’s, the cock that they used to ravish her every day. In her dream she was playing with it, stroking it faster and faster until cum was bursting out of its tip. When it was shooting cum, her “cock” began to grow longer and longer. Then, to her horror, she saw that the head of her cock, which was by now several feet long, had become a snake, and it was turning around, trying to kiss her…

She woke up, shaking and cold-sweating. Immediately, she looked down between her legs. She let out a sigh of relief and almost laughed when she saw that there was not cock there. As she was catching her breath, she heard the door open, and Catwoman and her henchmen walked in.

“Ah, I see that our Superslut is up already,” Catwoman purred.

“You’ve been watching me, haven’t you? That’s why you know that I’m awake,” Supergirl said.

“Oh wow, our Superslut has figured that out!” Catwoman teased. “Well, let’s see if you’re smart enough to figure this one out too. Get her ready.” At these words, two guards led Supergirl out of her cell by her leash. Next, they unattached the leash, uncuffed her wrists and re-cuffed them behind her back, and held her standing by grabbing her arms. “So how is our Superslut feeling after her big gang-bang?” Catwoman asked as she toyed with Supergirl’s nipple ring.

“I’m, I’m fine, mistress,” Supergirl answered timidly, remembering her punishment for insolence yesterday.

“Good, then I’m sure you’ll be ready for this.” Supergirl gasped in pleasure as Catwoman began fondling her breasts. Then, rubbing her breasts with one hand, Catwoman’s other hand worked its way down to her pussy. Supergirl closed her eyes and shuddered as Catwoman ran her fingertips gently along her pierced lips, and she moaned when Catwoman found her clit and began playing with it.

“Oh, oh, oh,” Supergirl moaned louder and louder. However, she was alarmed when she felt the same sensation of expansion in her clit again, and opening her eyes, she saw that her clit was indeed expanding! “Oh, God, Nooooooo!” Supergirl cried out in horror as she watched her clit grow bigger and bigger in Catwoman’s hand. It went on growing until it was about eight inches long and more than one inch in diameter. And it was shaped exactly like a cock, with a head and a hole in it. “Oh, no!” Supergirl cried out in dismay. Her nightmare was coming true. Not only had the size of her clit increased, its sensitivity had also increased manifold, and now every touch of Catwoman’s fingers was almost unbearable.

“So how do you like your new toy?” Catwoman asked giggling. “Dr Rancor has found out how to manipulate your protoplasmic body,” she explained, “and we have decided to make you the perfect fuck toy. You see, now you no longer need a strap-on, and isn’t that great?”

“Oh, no, oh, no!” was all Supergirl could say in her state of shock. She wanted so much to break free now, but weakness swept her over as Catwoman continued to play with her “cock”.

“Here, see what it can do!” said Catwoman, and with these words she squeezed Supergirl’s cock and Supergirl cried out as she was taken by a powerful orgasm.

“Aaaaaaaaah!” she cried out as spurts of her juices came jetting out of the head of her cock, spraying all over Catwoman’s glove.

“You messy slut!” Catwoman scolded, laughing triumphantly. Supergirl was still shaking after her powerful orgasm. She was too weak to resist when the two guards holding her pressed her head down, and she obediently licked her juices off Catwoman’s glove. She began sobbing as she licked. She felt totally humiliated. She has been turned into a total sex slave, a real fuck toy whose only purpose is to give and receive pleasure, to be used by anyone in any way they want. How can she be a crime fighter again even if she has the chance?

“Not happy?” Catwoman teased. “Don’t worry, my slut, I’ll show you this really neat trick. C’mon boys, give the slut a hand.” Supergirl had no idea at all what they were up to when they sat her down on the floor, and she neither resisted nor protested. She was too ashamed to speak. Grabbing her ankles, two men held her legs wide-spread. Catwoman came over and knelt down in front of her. She then held Supergirl’s cock in one hand and grabbed her head with the other.

“Noooooo!” Supergirl cried out when she realized what Catwoman wanted, but with the men holding her tight, there was nothing she could do. With the help of another guard, Catwoman managed to bend Supergirl forward until her lips touched her own cock. Quickly, two other guards came over and attached a chain to her collar. Then they ran the chain down her body between her legs to her back and attached it to her wrist cuffs, holding Supergirl in this posture.

“No! I won’t do it! No!” Supergirl shook her head wildly. However, her voice weakened when Catwoman began stroking her cock gently. The sensation was overwhelming. “Oh, no, please!” she pleaded, but even the feeling of her breath on the head of her ultra-sensitive clit-cock was too much.

“Suck it, slut!” Catwoman stopped stroking her cock and instead grabbed her right breast and squeezed it cruelly.

“Ouch, ouch!” Supergirl cried out as Catwoman continued to molest her breast. Seeing that Supergirl was still resisting, Catwoman took out a Krytonite alloy needle and slowly began to push it into Supergirl’s now bruised breast. “Ooooooh!” Supergirl cried out in excruciating pain. “Stop! Please! Aaaaaaaaaargh!” she pleaded.

“Then do it, lick yourself, fuck toy!”

“Ah! Ah! Oh! Y-yes!” Supergirl cried out finally. Supergirl was still shaking with the pain after Catwoman had pulled out the needle. Sobbing and defeated, she stuck out her tongue tentatively. When it touched the tip of her cock, her whole body trembled with the sensation. “Hmmmm…” She couldn’t help letting out a grunt of pleasure. “Yes, that’s it, slut! Do it again!” Catwoman said, and Supergirl licked her cock again, this time she let her tongue touch the entire head, and the sensation was incredible.

Now she could no longer hold back. Without Catwoman ordering her to, she licked her cock again, and again, running her tongue along its entire length. Shortly, she felt herself coming, and began licking faster and faster. She was totally oblivious of the people watching her, she just wanted to come. And within seconds she came, spraying her juices all over her face. Exhausted after her powerful orgasm, Supergirl just lay on the floor gasping for breath after she was untied. Her clit had now shrunk back to it normal size. Seeing that she was now completely tamed, the guards left her wrists uncuffed after they had chained her collar to her cell.

“Get some rest, slut,” said Catwoman and she leaned forward and kissed Supergirl’s juice-stained lips. “My boys and I are visiting the Metropolitan Art Museum tonight, and we’ll need you later for the celebration!” she said as she left. Supergirl wanted to cry again, but she was too exhausted, and soon she drifted off to sleep.

When she woke up, Supergirl could tell by her biological clock that it was already dinner time. Her body was anticipating the gang-bang that usually took place around this time. She tossed and turned on the floor. To her shame, she was hoping secretly that Catwoman’s men would be monitoring her and would see that she was now awake and come to get her. But Catwoman and her henchmen were nowhere to be seen. So they were still out stealing whatever they wanted in the art museum, Supergirl thought impatiently. Unconsciously, her hands reached up to cup her breasts. Then she began squeezing them gently. She was ashamed by her own actions, but she couldn’t control her body. She squeezed her breasts harder and harder, and tugged at her nipple rings.

“Oh, oh,” she moaned lightly. One of her hands slid down her body to her pussy. Resisting the temptation to play with her clit, she contented herself with rubbing her wet lips. But as she rubbed herself faster and faster, she could feel her clit throbbing, begging to be released. Finally, she couldn’t resist any longer and began tickling her clit gently. Immediately it sprang to life and grew to its full length.

Supergirl looked down at her clit, panting. Its use is to give all kinds of pleasure, Catwoman’s words echoed in her mind. This is my clit, it’s a fuck toy’s clit, Supergirl thought. I’m a fuck toy! she screamed in her mind. Closing her eyes in abandonment, she bent down and took the head of her cock in her mouth. Immediately, her whole body shuddered with the sensation. Slowly, Supergirl moved her head up and down and began sucking herself.

Dr Rancor smiled as he watched all this from a monitor. Catwoman had better be back soon, he thought to himself. Tonight is going to be fun…

The end??
