Gotham City was like a wild animal. Untempered and random in the way events spiraled into. Some might say it was the city showcasing its uniqueness compared to other troubled cities. Others might just label it troubled and move on. But there was always one group that tried to bring order to the chaos that reigned in Gotham. One ruled on high by one known as the Batman.

Chaos was very much what is currently called striking various chemical plants around town. Heists of various highly rare liquids. Gotham Police determined them randomly. Possibly given their explosive nature a gang preparing for a series of robberies.

But the Batman knew differently. Yes, some of the compounds if mixed could be explosive. But there was an alternate brew to them as well. Though not the same exactness of what was in the past. The same genetic match of what could be brewed from them the end result: an inhuman result, becoming a Man-Bat.

Kirk Langstrom developed the formula for the noblest intentions of furthering the human body. What it did instead was give birth to a ghastly creature. A creature was as if it was Gotham itself. It had no desire to be itself.

But as in other situations, this persona was beaten down and Langstorm was cured of it. Or at least, that is what Batman had thought. The current string only could mean one conclusion. Langstorm was trying to replicate the formula. At least that was the simplistic approach. However, given Gotham City was wild, Batman couldn't fully devote his time to the case. So he had Oracle pass it on to another.

Oracle with her vast knowledge of the web found documents of Langstrom's latest jobs. It wasn't surprising at all to learn his latest job was at the Gotham City Zoo being a veterinarian to the bird exhibit there. Which again clued her in that Langstorm was closer to the end goal he was searching for.

With the location of Langstorm confirmed, Oracle would call for her successor, Cassandra Cain, also known as Batgirl. Oracle made sure to keep the briefing quick but also enough for Batgirl to know about the situation. Once finished, Batgirl quickly embarks on the Gotham City Zoo in hopes of stopping the Man-Bat from making his dreadful return.

Entering through the gates of the zoo, Batgirl noticed how quiet the place was. Too quiet for comfort. Even the animals were too afraid to make a sound or move out of their resting areas. Then suddenly a loud screech echoed out of the vet’s office. That was not a good sign. Batgirl rushed to the door only to find it locked. Without any choice, she kicked it down to gain entry.

Batgirl was greeted with more silence once again. The room looked like a massacre. Scratches on the walls, broken vials on the floor, chairs and tables misplaced, and what appears to be Langstorm’s lab coat. Batgirl walked over to it and picked it up, finding the ID that showed a picture of his face and his name “Dr. Kirk Langstorm”. Not good.

Batgirl reached for her earpiece and pressed it to be online with Oracle. “Oracle, this is Batgirl. I’m too late. Contact the team and let them know that Man-Bat is back.” She was cut off by the sound of smashed glass. There was a good chance he was still here. “I’ll continue my investigation here. Batgirl out.”

Heading downstairs, Batgirl saw some more scratches on the wall, and used it to track down Man-Bat’s recent whereabouts. It led her to a dark and creepy laboratory. So much so it came out from a horror movie she watched with Spoiler. If only Stephanie were here to see this. She would make a quip in an instant. “I sure do LAB being alone in the dark…” Thankfully, no one was there to hear that.

There was silence at first in the darkness, until a ghastly mangled voice let out amongst it. “A female…. Gooooooooood…” The deep voice was garbled hints of a higher tone. “I knew the trail would bring one of yooooouuu to meeeee.” It was obvious to Batgirl that whatever humanity was left within Langstorm wanted these words to be known. To be heard. Not just for her to hear but to whomever would find any clue to what was about to transpire here.

“Humanity neeeeedss to– EVOLVE. To spreeeead its wings. I’ve been tooooooo seeeeeelfish in denying humanity my GIFTS. Keeeeeeping it to myself. Not anymore. Tonight a neeeeeew age beeeegins in Gotham. It begins with me–”

The voice was echoing throughout the room. Too hard to pin down. Too unpredictable for what was to happen next.

“-- AND YOU!”

Langstorm sprang behind Batgirl his long clawed winged hands grasping at and picking her up. Throughout the jagged broken glass around them, Batgirl could see Langstorm was almost completely transformed at this point. His mouth half bat, half human drooled as it was obvious whatever humanity was within him still was fighting the serum in his system.

But not for any good. No. It was so he could talk to his victim. To Batgirl.

“Langstorm…Kirk, I know you’re in there. You can still…fight this.” Batgirl chose to talk it out with whatever was left of Langstorm in hopes of not resorting to violence. She believed in redemption. She believed in everyone, both friends and foes. She believed Langstorm could still be saved. That even if there was a slight chance, she would take it. Batgirl rests her hands softly on Man-Bat’s clawed wings as she looks up at him.

As hopeful as she was, Batgirl’s efforts would be proven fruitless as she felt her back land hard against something made out of metal. A bit of blood coughed out of her mask. Before she could sit up and recover, her arms were pinned down by the massive hand claws. Batgirl struggled. Shifting her arms as much as she could to break free from his grasp. The drool fell on her face, catching her attention as the prey looked up at her predator. “Kirk…” Batgirl pleaded, desperate. Her only hope was the man behind the bat.

Langstorm’s one blue eye grew wide at not the mention of his “human” name, but the sudden smell of blood in the air.

He had hurt Batgirl. The one thing he was trying not to do and failed. There was a slight sadness in the one eye as more of the Man-Bat formula continued to overtake it. The red curls of his hair and pale skin disappear into brown fur, while his ear slowly twists into a bat’s ear.

“I’m sorry.”

He let out with a whimper as he released his tight hold slightly on Batgirl switching to use his body to keep her still. With his growing winged hands free and starting to drape over her form, Langstorm used what remained of his human fingers that were being consumed to be more bat-like as he found the slit between her mask and the top around her neck.

The clawed digits began to push up on the fabric exposing Batgirl’s face. The bare skin of her neck was exposed and the curls of her black hair started to fall out. When her bloodied lips became revealed, Langstorm stopped and nuzzled his mouth against hers. His maw opened as a long tongue lapped at the blood against her lip. The salvia wiped the blood from her form.

Tilting his head against her head, Langstorm. “I’m glaaad it was yoooooou– Cassandra.” His hips pressed into hers slightly. “I’veeee madeeee a neeeeew formulaaaa. Viral. Passed on one being to anotheeeer.”

Langstorm paused finding the words were becoming harder for him to say. Not due to his mind retracting due to its animalistic nature. Again his large mouth opened this time the tongue running against the lips of Batgirl’s.

His hands that were once against her shoulders began to dip lower. Lower until they began to reach her chest and touch her tightly covered breasts. Though again, Langstorm was holding back. Not for his humanity, but to explain the rules. The stages of what he was intending to do to her.

Within her mask, Cassandra grimaced feeling the slippery appendage run against her lips. She licked as the warm sensation of her blood was now replaced with the wet simmering salvia of Langstorm. When he began to fondle her chest, Cassandra pushed and squirmed her legs trying to find a way to escape his grasp.

As she did, her knee felt something large yet soft. When the realization dawned on her, Cassandra shuddered as she continued to struggle against him trying to deny Langstorm anything of hers. But then she saw IT.

The large hulking bulge between the tattered remains of Langstorm’s pants pressed into her knee. Her mouth dropped at the sight of his erection. Then a cold shiver hit her at the realization that his belt was broken and hanging from his straps. Whatever button that held the pants had long since been gone. The only thing holding them on Langstorm’s form at this point was the fly ironically massive erection straining against the cloth.

However, as her knee pressed into it, she saw the zipper slowly dip. The other “beast” within Langstorm was getting larger and the accidental rubbing she was doing was helping to free it from its confines. Cold sweat began to drip from her hair and trickle down her face as her mind snapped back at realizing he was trying to speak again.

“Passed via fluids. Your body will crave mine. Wheeeen eeeenough of mine is within you. You will become ME. ” Now his clawed fingers grasped at her chest harder now. Seeking what lay within the tight restricting fabric. Again, his tongue sought her lips teasing what the long tongue could do to her.

“Once me. You will HUNGER. Hunger for others. Your friends. Make them ME. Make them US. Then Gotham City will be the city of bats!”

Batgirl tried to speak, but his long and slick tongue made it difficult to do so. Even her words are having a hard time trying to break out from his animalistic grasp. Her insides felt warm, which shocked her as she didn’t want to give him a reason to continue. With the squirming of her legs and the muffled whimpers, Batgirl began to realize her body was yearning for more. The heat was rising in her form, but her mind refused to yield to it. He must have done something to her, surely. She was not usually like this. Her brown eyes grew wide at his prior words as they were coming to pass.

SHE HAD TO FIGHT THIS!
She had to fight this!
She had to fight this.
She had to....
.... had to.... ....
.......

When Langstorm’s tongue pulled out of her mouth, Batgirl panted to catch her breath. A mixture of their drools dripped down to her chest. There was silence save for the panting sounds of the pair’s breaths as both recovered from the embrace.

Batgirl’s mind began to haze, her cheeks reddened, the heat in her body sweltering, and her hips jolting slightly to his hardened crotch’s touch. Finally, Batgirl slipped one hand to freedom, but instead of fighting her way out, it went into the opening valley of his pants. Her hand grasped at the slab of meat, as her finger was tracing against the tip of his length. She had to stop him. But... maybe yield at least to quell what was also burning inside her.

“Kirk…you…you can have me…Just please…leave Gotham and my family…out of this…”.

Langstorm was expecting still full-on resistance from the most feared fighter out of all the vigilante bats. Instead, astonishment was what surprised him along with her words when the gloved hand dipped inside his barely held trousers as she went with her word. The move caused a loud growl of excitement from his mouth. Feeling her gloved hand run against his massive phallus and then grasping at it stirred something within him. An equal yearning, but a realization that the virus was working, and bit by bit she was breaking down before him.

He leaned into her as Cassandra pumped at him. The move caused the last friction of his fly as the last inches gave way and caused the tattered pants to fall down his form and his organ freed with her gloved hand jerking it. It wasn’t long before more growls escaped Langstorm’s fully transformed lips. This time of grunts of pleasure.

Batgirl now felt a drip of excitement coats her gloved hand. The excitement then grew to hunger. As she sat up, she dropped before him as she brought her face closer to what she had been pleasuring, the scent of his pre cum driving her urges further. It emasculated her will to resist. With her lips merely inches away from the head, her soft breaths brushed it.

Before long, Batgirl planted a kiss on the tip, rolling her tongue out to lick the Bat’s excitement clean. Because of its massive size, she resorted to using both hands to slowly stroke it, up and down. Langstorm’s ragged groans made her ears ring, the sort of reaction to motivate her to continue. Batgirl peppered some more pecks, feeling it twitch in response. Langstorm must have been so lonely, wanting people to accept him for who he is. Instead, they called him a monster because of his appearance.

Batgirl understood what it was like being alone, hiding from society out of fear of becoming a threat. She isolated herself, watching others live a normal life she yearned to be part of. Surely that's what Langstorm was going through. Why else did he want her to be just like him? “You’re not…alone, Kirk.” Batgirl looked up at the beast, her cheek pressed against his aching length, her finger tracing circles around it. “You don’t have to be alone anymore…I’m here. And I accept you.” A warm smile of assurance grew on her face. Batgirl stood up so their faces would meet. She cupped the cheeks and watched as the Man-Bat’s form began to transition completely over the remains of Langstorm’s humanity.

“I will protect you…”

The brown fur of a bat continued to encircle the last corners of his human flesh as his eye stretched and the once blue hue orb had gone fully yellow.

“You will…”

The animalistic nature of the Man-Bat was here. Whatever the voice remained were the echoes of the drifting rags of humanity on the creature.

“No… You areeee my knight in thiiiiisss– kiiiiiiiingdom. Kingdom of bats!” Out of nowhere, Man-Bat pushed at Batgirl her full form hitting the slab behind her. Laid out on it his winged arms pulled her legs up as his head went right between her leggings repaying what she had done to him tenfold.

The long ravenous tongue feasted on the tightly covered slit. Feeling the heat building and more importantly, the juices seeping. Drool again dripped from the Man-Bat’s maw as it lapped at the area and the hungering to fully feast on the bare area growing within the creature.

Batgirl arched her back as Man-Bat wasted no time in devouring her entrance. A loud squeak escaped her as she wrapped her legs around the head of the beast in heat. She gripped on the hair and pulled him closer. Which elicited a violent response as she felt her pants be ripped open by his clawed hand, exposing the excitement that was dripping down her thighs. Cassandra only groaned louder and arched her head against the slab she was on.

The gripping was only partly why Man-Bat tore open her tights. More it was the juices. Tasting them through the fabric wasn’t enough. He had to taste them bare. Taste Batgirl’s sweet sex without any restrictions. When his clawed finger tore open the area and saw the sweet pulsating soaking pussy, Man-Bat dove right in.

When the beast’s tongue penetrated into her walls, Batgirl shuddered. It was so warm and so big, exploring, licking, and feeling any spot he could reach. She held her breasts, squeezing them together before circling her finger around the tit. “Kirk…” Batgirl pleaded. The thought of his massive size was already in her mind. His teasing of her lips and lapping the juices up made her yearn for more.
“I’m ready…”

The creature paused its assault on her feeling the way her hips and body responded to his savage desire. She wanted more. She was yielding fully to him now. Body and mind. So the beast gave into what she hungered for. He rose and heaped his form onto her.

Inch by inch his massive girth entered her womb filling. Then without any warning, he gave his first thrust into her. Then another. Another. The creature grunted at feeling the tightness of her womb, yet the massive girth continued to push into her.

As he fucked her his body felt something press against him. His clawed finger ran across her breast and bud fully erect through her suit. Leaning down Man-Bat bit into the fabric pulling it up as the suit tore exposing the pointy brown nipple free along with its opposite. Soon the lone digit on both his wings ran across her aching buds. Teasing it as the rag of fabric with her bat symbol remained clinging to Man-Bat’s jaw like a trophy.

Batgirl’s walls held his massive size like a vice grip, her breaths ragged, and her voice increasing in volume after each thrust. With her breasts now exposed for his viewing, she returned the favor, clawing against his chest and leaving a mark. She wrapped her legs around the waist, making sure he didn't go anywhere. Not until she was satisfied.

She pulled Man-Bat close to her as she licked his maw, inviting him to do the same. Soon their tongues touched, danced, and swirled around in a passionate fashion. Batgirl reached down with her free hand, rubbing against her sensitive clit to heighten the pleasure. She graced his ears with her non-stop moans, the table now squeaking with how rough it had become between the two.

The virus was taking its full effect on her, she was utterly broken, claimed by sex. Craving for more contact. More lewdness. Something the Man-Bat was all the more willing to give the Batgirl. His hips went harder into her. Pushing himself further. The maw with the ragged symbol that was once on her chest now ran across it when she fondled herself. The long slick tongue sought her’s as it fed her more juices. More of a mixture of what was within him.

She was his now. More than she ever knew. But she would SOON...

Cassandra’s mouth welcomed his long tongue, feeling it pushed into her throat. She sucked on it and drank the mysterious and yet salivating mixture. It made her crave more. Made her HUNGER. The lust. The thrusts. The tightness. That was all in her mind.

When she felt the intrusion in her mouth pull out, Batgirl panted in an effort to catch her breath. Her tongue rolled out, and her chest rose up and down. She could feel the heat in between her legs. Something was coming. “Can’t…hold on…” Cassandra muttered, her mind slowly becoming even more hazier. She gripped the beast’s arms, nails dug deep, as she experienced her orgasmic release, coating the length with her excitement.

Man-Bat felt Batgirl climax hard, as her juices coated his organ, and could feel its own coming. It hammered harder into her, wanting the release of its own juices within her. It plunged its cock fully into Batgirl now. The way her walls reacted and reached her was all that Man-Bat needed to explode in his own orgasm.

Making sure his juices were fully staying within hers. The creature tilted his head slightly seeing the way the woman below him was reacting. Her mind was almost completely gone at this point the serum within him working its effect on her. It was time for stage two to begin. The unfortunate (or was it fortunate?) side-effect of the new virus coursing through his body was eager for another round. His cock remained hard and his balls were still filled with more seed to unload into Batgirl’s womb. There was the possibility a body could theoretically die from having too much sex. But with the heightened metabolism, Langstorm had in the past with becoming Man-Bat he again theorized the mutated body could hold out for a long time until the bodily urge for food and sleep would come.

As he could feel the last bits of his cum exit his tip, Man-Bat picked Batgirl up Her bare chest crashing into his. With his long hard cock still within her, the creature held onto her as he began impaling her onto his shaft now. The way her body reacted was quite amusing.

Batgirl wasn’t given any time to recover as she was soon picked off the metal slab and onto the beast’s arms. The forced intrusion into her walls caused the girl to let out a loud whimper. Her mind was still dazed from her orgasm, she lost the feeling in her mouth as it was left agape, making her tongue roll out. Batgirl held on as she could only watch Man-Bat please her to his liking.

Again, Man-Bat opened his maw and his long tongue feasted on Batgirl’s human lips. The tongue bath was so much part of her mask crept up more to expose her nose and an eye. Not soon after more of her drenched black hair began popping out to the side with each time he slammed her into him with force.

Sadly the bat symbol that hung on his mouth fell as gravity tore it free from the area. No matter to the beast at this point. It pushed Batgirl back slightly to graze its teeth slightly against her pointy brown nipples wanting to taste the area anew. Man-Bat wanted to savior this form of Batgirl’s.

The first human to succumb to his new virus. It was only a matter of time now before phase two would arrive after her mind fully shattered into wanting more and her body would reshape itself into being an actual bat-human hybrid.

At this point, Batgirl had most of her human face revealed due to the way Man-Bat was impaling her on his large member. Each time he brought her upon him, the mask came loose further. The pattern continued until the whole mask fell to the floor, joining the shredded bat symbol.

Even with the exposure, her shoulder-length black hair was soaked in sweat. Both her brown eyes were now rolled to the back of her head, her mouth still open with a mix of his and her own drool seeping from her mouth onto both of them as her tongue lay still hanging from it. Her exposed breasts bounced each time her body was forced onto him.

And her sex? Her pussy was gushing with wetness and heat. Each time she fell upon him a loud moan came from her throat. Her mind was gone at this point. With the hunger of lust all over her the virus began its final stage.

A sudden new tingling sensation ripped across Batgirl’s entire body. Suddenly the pitch in her voice was higher than a human’s when Man-Bat’s cock entered her. It was primal. Then a new sensation came to her as she felt the cool air hitting her form a new as the rip between her legs was growing. Not due to Man-Bat’s hard fucking of her. No, Batgirl’s body began to change as the virus’s next stage was taking hold of her.

The vigilante next felt her teeth sharpened into fangs and her nails ripped out of her gloves. One hand gripped the beast’s hair, and the other clawed on the back slowly. A lighter dary gray fur began to seep from her human skin starting to cover her form save her hair on top which was all that remained of her humanity. Her pupils shrunk into pure yellow as Batgirl felt her animalistic side continue to come out.

She sank her teeth into Man-Bat’s shoulder, wrapping her legs tightly around his waist. He had nowhere to go because she wanted more. After she did this her boots began to be torn apart as her new feet began to form and emerge from the broken remains of them.

Thanks to the serum, Batgirl’s strength doubled. She pulled the beast that had corrupted her against the metal slab, switching their positions as she stayed on top. Hands resting on the chest, Batgirl slammed her hips hard to his massive size. The sounds of skin coming into contact would echo throughout the room. Her loud shrieking turned to growls. She clawed his chest as her movement didn't stop. Her own chest tore at the top with some rags and her utility belt clinging onto her form. Her mounds were heaving large as the still-roused areolos peaked through the fur. The human-sized suit ripped out slowly from the increase of mass, the form of the clawed wings, and the growth of the Bat maw and ears.

Most of the shards of her suit her “human” skin were all over the floor now. The transformation was complete. Batgirl was fully transformed and a Girl-Bat with the tattered remains of her past humanity barely clinging to her form. The all too willing aide to what Man-Bat wanted. To purify Gotham City. To make it the city of bats. Girl-Bat would be the weapon to halt those who’d try to stop him. The human family who called themselves Bats. Though, perhaps she would make them literal ones with her sexual hunger.

The new Girl-Bat howled and wanted more from her lover, but also hungered for more than just him. Something stirred within her. An urge not just to continue to mate with him, but to mate with another. She leaned and bit at maw with her own as one name and image recurring. Stephanie. She wanted Stephanie. She had to get Stephanie. The thought of ravaging her blonde friend got her all the more excited as the love-making turned aggressive.

Man-Bat was amused by his lover’s aggression toward him. The hard impact of her hips slamming into his heightened his drive for her further. He wondered how a human male or female would last against her. With how passionate she is, the human will have to endure her relentless sex drive. He would be lying if he said he wasn’t envious. A part of him almost wished he could follow her to witness the spectacle, perhaps even join in as well. The human may have fun with his lover, but he has to set a point that she belongs to him alone. Alas, his own desire for her had to be quenched. For now, it was raging not for this ravaged human but for an actual equal. A true mate. One who could take everything he dished out.

Her labia larger as his own organ continued to take in. The slushing sounds as they made love could be heard echoing throughout the halls. Orgasm after orgasm claimed the other. But neither was finished toward the other. Until their bodies, all drenched in sweat finally hit their limits and passed out against one another. Both heads nuzzled against the other while their juices seeped from their sexes dripping all over the table and floor. The mating ritual has been completed.

Time was at a loss for both until Man-Bat stirred and moved away from his mate. The hunger to repletion his metabolism was sorely needed. No doubt when she awoke she’d need the same. However, for now, this was the time the two had to say their goodbyes. For if he was to succeed he’d have to leave his mate.

As he flew away, Man-Bat knew whoever was to stumble across her now would have to deal with the beast of mate and she too would corrupt them. For a while, she dealt with his enemies, and to distract them he would spread the virus through easier citizens. First, however, he would pay a visit to his human wife Francine. After all, a ruler needed more than one lover…

And soon Gotham would be a city of bats…
