New Haven University was a place of learning. Learning, enlightenment, and experimentation. Backed by government funding and private corporations, it was a site for many groundbreaking projects in science. The brightest of college students often ended up here to be shaped into the greatest minds of the generation, ready to invent the next biggest thing to forward humanity.

Here in one of the science buildings, Aela Jinnah toiled at work on her own time. Her project involved utilizing the latent abilities of common arachnids. Aela honestly thought they were repulsive creatures, but she was a specialist in biology and chemistry. Her most recent work was aimed at trying to synthesize and mass produce a variant of spider silk, with the tensile strength of steel. Simply dubbed 'silksteel', the possibilities with it were endless. Clothing, thread, rope, armor, the applications showed much promise for her benefactors.

The concept was simple, to her at least.
1. Get genetically altered spiders! (Little ones, hate tarantulas)
2. Have them possess increased fertility (Try not to have them kill eachother would help)
3. Compel them to spin constantly (make sure it's unbreakable webbing)
4. Build machine to harvest as they go. (Rotate in place in cage?)

The lab she moved her research to, however, was not the most well-maintained. The equipment was old, invisible cracks, and possibilities of cross-contamination were likely. She ignored these possibilities, hell-bent on giving her benefactors results. They've put pressure on her a lot lately, and threatened to cut funding if she didn't give them anything solid. She had yet to pass the second hurdle of her plan, and needed a breakthrough, quick. Several burners were on, tending to heated chemicals, while rows and rows of genetic samples littered the room in beakers and tubes. In a few plastic cages were the tiny spider subjects, some living, some dead from experimentation.

When the inevitable lab explosion happened, no one else was around to help, and fumes from the mixed chemicals clouded the room. A fire somehow broke out, and genetic samples and unstable compounds were breaking and spilling on the floor. Aela coughed, struggling to get to the door, but never made it. She fell to the ground, unconscious.

Two hour later, a text was sent from Aela to her most trusted friend. All it said was this,
'It's Aela. Meet me in the basement of the B7 building. I know it's dark out but this is urgent! It involves my research.'
 
Kairi Shindo was Aela's girlfriend, enjoying every part of the girl's life she wanted to share. The duo were almost inseparable. Wherever Aela went t hang out she always had her lover follow, refusing to let the girl get away somehow. For almost 5 years now they've been together, Kairi supporting the girl once she dove into her research, the girl herself preferring a more relaxed lifestyle, herself simply going to school to be a chemist. She wasn't into doing big projects on her own like Aela was, so she offered help at times when she was asked.

So when she received a text from Aela, asking to come to the basement level, she trembled a bit, unsure why the girl was down there to begin with. But if it was for Aela's research then she would gladly face er fears and worries and go there. So with a weak smile she tread the halls after leaving her apartment, looking around until she made it into the basement of building B7. The whole time she walked she could only imagine what brought Aela down here, what kind of spiders was she looking for? Did she decide to move part of her lab into a more dark, damp area for better results? However, It only dawned on her then that there was an explosion a few hours ago in this building, since then she had heard nothing from Aela. when she realized this she really began to worry and wonder if maybe something went horribly wrong and Aela needed her help. So with a whine she hurried down the halls of the basement."A-Aela?!"She called.
 
The B7 building basement was mostly used for storage for the labs above. This meant, of course, that it was using equipment from the past decade, and was even less maintained than the rooms above. Cobwebs littered the ground everywhere, but no spiders were to be found. One failing lightbulb flickered and pitifully tried to illuminate the whole room. Only half was dimly lit, the other half was conveniently blocked off with old storage crates. As Kairi walked down the stairs, she could hear Aela's voice, and make out her upper body behind the boxes. Something was wrong, she seemed much taller behind there.

"Good, you're here! Look, something went wrong! I- I was trying to make progress on my lab project, and, well, stuff blew up, I tried to escape, there was a fire, and I passed out! I thought I was dead, everything hurt, but I woke up, and- and... just look, DON'T SCREAM OR RUN AWAY! It's still me." Kairi could hear the clamoring of multiple feet tap the ground as the boxes were effortlessly pushed out of the way. What stood before the student was a sigh that would frighten most people. It was Aela, no doubt about it. Her glasses were missing and the white laboratory coat she wore was only held together by a few buttons, evidently from an expanded chest. That was where the humanity ended. Behind her was a grotesque arachnid abdomen, with eight additional legs and everything. webbing seemed to fall to the ground as she walked forward, trying to control her new bodily functions.

"PLEASE don't run! I, I don't know what to do! I don't know why this happened! I... I don't know how to fix this, if I can." While it was a fearsome sight, Aela looked scared, desperate. Tears were welling up in her eyes from the trauma.
 
Kairi walked cautiously once she got to the basement, the dark damp hallways making her shiver. This place was abandoned years ago when the newer lab was moved above the basement. Since then cobwebs grew and the walls were cracked and lights nearly dead due to lack of power or just faulty old lighting systems. but when she heard a familiar voice she smiled slightly and quickly moved to the source of the sound, only to fnd Aela who now looked to be a bit taller than normal.

She was a bit confused at first when Aela explained something went wrong with tests and pleaded for her not to run away. She could only wonder why she would say that as worry took her once more. Just what could have happened to her girlfriend to make her so fearful, so afraid of what Kairi thought.However, when she stared upon Aela's new body with wide trembling eyes, she fought hard not to scream, her breathing shaky and hesitant. She so badly wanted to turn and runaway, fear taking her as she stared upon the woman's new figure. But just before she could she noticed the tears that welled up in Aela's face, the worry that pained her as much as it did herself. So with a whine she nodde.d"I-I won't run..I promise.."
 
Aela seemed to mellow out, taking comfort in the fact she wasn't alone now. She wipes the tears from her eyes as she started to plan on what she would do.

"Okay, okay good. I'm scared Kairi. I don't know what to do. I can feel things just, moving, inside this thing that grew out of my back. It'd be fascinating if it wasn't happening to me. The things I could learn..." her mind drifted, on what she herself would do to a specimen like this. Her face frowned then, the fact was SHE was the specimen. Aela stared down at her friend, walking closer to try and make a point.

"No one can know. Do you understand? No one! They'll keep me in a lab Kairi! They'll do experiments and cut me open... got it?" It waz asking quite a bit, but Aela was sure that if she was discovered, it would be the death of her.
 
Kairi shivered as Aela explained what she was feeling, the girl shaking her head some as hse listened, unsure what to think at the moment. The fact that Aela was so fascinated by this and also afraid mad Kairi wonder just how well the girl would take to her new body. At the same time she could only imagine how much of her, both mind and body would work like an arachnids. But whatever she could do to help Kairi would do her best. But it also meant she wouldn't be able to really enjoy the things she used to with Aela in their apartment. The mutated woman would have to remain down here to avoid getting cut and experimented on.

"S-so what do we do now Aela..?"She asked with a weak whining tone, part of her growing depressed to find her lover in such a undesireable predicament.
 
"I, I have to fix this, somehow." Aela mused, pacing back and forth on her multiple pairs of legs. One or two stumbled every once in awhile, but due to there being eight it wasn't too bothersome, and she never fell to the ground. She was still clearly getting used to her new form.

"I'll take lab equipment, hide under the school or something. This isn't a bad place for it, but I need something better, something noone has no reason to go to." As she paced back and forth, her insides were shifting uncomfortably. Changes and alterations were still occuring, and the more Aela tried to plan out how to fix this, the more difficult it was to draw her eyes away from Kairi. A familiar sensation began to well up in her chest. A sensation that was beginning to pervade her thoughts. The spidermorph eventually stopped pacing, eyes fixed on Kairi. She turnes to her, beginning to get uncomfortably close to the human as she was plotting something new now.

Her question, however, was sincere, as Aela still cared for Kairi more than anything in the world. "This doesn't change anything between, us, right? Can we still be together. Even with this body, I'm still human... can you show me? Show me you still care?" She towered over Kairi, a head above her, but Aela leaned down so they were both at eye level.
 
She began to think about where they could move her set up, somewhere larger to support her larger form. While she was thinking about this she was still getting used to the change her girlfriend had gone under. She was still trying to understand exactly what it was Aela could have been working on that caused this change, that caused the mutation to hr body. " Just what kind of experiments were you working on exactly?"She asked, hoping it gave a clue as to what they could do to change things. In the meantime she smiled softly, having an idea of just where they could hide her.

"What about the abandoned storage warehouse beneath the college? from what the maps of the schools show its been abandoned for years after the campus was rebuilt."It was large, still took in power and never had any visitors or anything to catch them. It as perfect for Aela to do her research in peace and still be closeby for Kairi to visit. Which caught her attention next when she caught those lustful gazes Aela shot her. She knew when her lover was horny and this change didn't seem to affect that simple need, that desire. but this time she had a darker, hungrier look than usual. Aela was everything to her, she was the perfect lesbian lover and gave her pleasure she couldn't deny. So when her love was questioned, Kairi stood up a bit more, planting a soft, passionate kiss upon the mutated girl's tender lips.
 
The storage area underground was an excellent idea. Aela made a mental note for later, and tried to ignore her prying questions to her research. She had a different goal in mind at the moment. Everything was meaningless apart from the kiss they were currently sharing. The inside of Aela's mouth stayed relatively the same, apart from one thing. As their tongues danced with eachother, Aela's arms wrapped themselves holding her lover tight. Baser instincts took over, and Kairi felt a sharp stinging sensation pierce into her tongue, followed by a sliver of warm liquids working it's way into her mouth and then her body.

Aela instantly released her grip, pulling her mouth away, unaware of what she caused. Her lips remained opened, and a string of green fluid ran from Kairi's mouth to a pair of sharpened canines in the mutant's mouth. Instantly she was worried again. "I-I didn't hurt you, did I? Oh god, I don't know what that was, what was I thinking!"

The venom in question was actually rather weak. So far, it's purpose was simple; to incite arousal in anything it got into.
 
Kairi tensed up with wide eyes when she felt the sting to her tongue, the girl whining softly with a light sting of pain. But before she could complain the pain faded thanks to the hungry kiss she had still exchanged with Aela. She took in a breath when the mutant pulled away, Kairi licking her lips, unintentionally pulling in the green fluid, her body slowly heating up. Before she could even realize it she was getting aroused, the venom doing its just as her panties were already getting stained with her juices between her legs. However Kairi ignored it for now as she kept close to Aela."N-No..you didn't really hurt me baby..Relax ok..? We will figure everything out I promise..."
 
Her reassurance calmed Aela down, always the more eccentric and more sensitive of the two. She reluctantly walked back up to her lover, holding her in her arms once more, just to show her appreciation. "You're brave, Kairi, for sticking with me, you know?"

Her nose twitched as she could smell the effects of the aphrodisiac, her eyes trailing down to see her handiwork. The sight of it only made herself more heated as well. Aela began to grind her body against the human, rubbing both of their sexes against eachother. The spider's hole was equally wet and completely exposed, a slit that was formed between the chitinous plates. She was relieved that this part of her biology was unchanged. While Aela felt a pressure on her own clit, she paid it no mind, content to rub against her lover and observe just how worked up the venom would make Kairi.
 
Kairi smiled and closed her eyes, enjoying the hug with Aela. Given the lack of attention they had given each other lately because of the research, she was sure both of them were due for some fun, but she had no idea how it would work or what might happen. But once she realized that her lover was grinding into her, the girl shivered a bit with a hot breath, feeling the juices from Aela covering her pants, her own soon drooling down her legs. She couldn't figure out what brought her own arousal on but didn't complain."A-Are you..horny too?"She asked as she looked down at Aela's crotch, glad to see her cunt had not changed along with the rest of the arachnids figure.
 
"Why don't you poke a finger down here, and test it?" Aela playfully teased, reaching one of her hands back to undo the remainder of the buttons on her shirt. As it fell to the ground, she let out a pleasant sigh now that her breasts were no longer restricted by it. Before the girl had nearly a flat chest. Now her altered body had granted her a nice pair of Double D's. This was one part she wasn't complaining about.

Aela swore the intense feeling she felt was on her clit. It was the only body part she could identify. Instead, the pressure was coming from above it. The sensation soon turned to pure joy, the unknown organ shifting was making her moan uncontrollably. The same compartment that concealed her female sex earlier, slowly began to break open as her arousal increased. She gritted her teeth, panting to herself as if she was trying to push something out of her, which was exactly the case. Flesh began to sprout from the crack in her armor. The recognizable head of a penis soon pushed out, a colored mixture of green and black up and down the entire length. As if to accompany it, a modest pair of testicles also slipped out, partially concealing the mutant's vaginal cavity and leaving her stunned.

"I... You're kidding me, I have one of those too?" Aela griped, staring down as her newly sprouted cock seemed to move around on it's own, as if it was prehensile. Small bumps ran up and down the shaft, seeming to leak the same green fluid Aela injected earlier.
 
Kairi bit her lips some, almost ready to reach down and finger her lover. But Aela's groans and sounds of slimy sploshes caught her attention more as she stared. the female watched n utter horror as more of the chitinous plating broke away, now revealing a cock and balls. The mutant seemed to possess both forms of reproduction, the grl shaking with wide eyes. Shock alone sent her stumbling back onto her rear, breathing heavily as she stared at the multi colored cock which seemed to covered in numerous bumps, almost like the perfect sex toy. But even still she couldn't believe what she was seeing, watching the twitching cock leak green fluid, her body reacting but making her slit drool more."B-But how? How is that possible..?"

(How big is it length and thickness wise?
 
(Good question, knew I forgot something.)

"I- I don't know! I tinkered with the subject's sex drive and considered all possibilities for them to reproduce quickly! I never got past that phase, but none of this should be possible..." As if it sensed a hole nearby, the almost alien cock extended towards Kairi, but failed to even get close since she backed away. It seemed to have a maximum length of one foot on close inspection, and was nearly two inches wide.

Already roused by the prospect of mating, the cock dripped more traditionally colored fluids from the head. Human seed seemed to spatter the ground below it in drops. It was an extension of her desires, and Aela still desired Kairi. Aela's eyes followed the movements of the new appendage, almost hypnotized by the way the thing moved. She reached one of her hands down to touch it, and both she and the cock twitched slightly in response.

"I can't believe this... " Tearing her eyes from her own lust, Aela looked back up at her lover, seeing the surprise in her eye. "I... I won't force you. I can't ask you to Kairi. I understand if you, stop, now."
 
When she was told just what Aela was doing recently with spiders she could only think that that mutation alone was what caused the cock to grow, the lust to build within Aela. Part of her wondering as well if the bite caused her jump in arousal. All the signs as of late pointed to that fact but by now she was too far in to turn back now. she had to help Aela, help her return to normal and get back to a normal life. She only hoped this could be reversed before it was too late. Aela was already getting more and more lustful, given the look she gave Kairi and the way she seemed to react to the touch of her cock as it moved, as if aiming for Kairi.

The girl forced herself to her feet, her legs shaking as arousal built inside her. The fluids that leaked to the floor drew the fumes into her nose, only skyrocketing her arousal more, her slit pulsing and drooling heavily. Her nipples hardened beneath her top, the girl fidgeting and squirming as well."I-I'm getting..s-so hot..w-what's...going on..."She whined softly.
 
"I don't Kairi, I don't know, I just..." Aela failed to give a real explanation. She had no definitive answer, but she had a good guess. Her body was producing copious amounts of stimulants to make Kairi more suggestive. That fit the woman's behavior so far. Seeing her get up and walk forward encouraged Aela to resume her work, crawling back up to the human and embracing her once more. She stood tall, and pressed the woman's face into her cleavage, creaking her head slightly to watch the spectacle below.

"Let's just sit back and see what happens? An experiment. I'll see, eh... I'll see what happens, 'kay?" As if it knew that hole had returned, the tentacle-like appendage reached out to press against Kairi's entrance. There was no foreplay, no teasing. Aela saw her best friend needing release and wanted to grant it to her now. Both the cock and pussy were already wet, once the head managed to slip it, almost half the length came with it. Immediately it began to piston in and out, forcing more and more of it's meat inside. The fluids were mixing inside the human's vaginal cavity, pre-cum, feminine juices, and slimy aphrodisiac all mixed in, providing plenty of lube.
 
( want her a virgin or no?)

Kairi nodded in agreement to the idea of just seeing how things go. But before she could really enjoy the embrace and nuzzle her lover's new chest, she felt something rub and prod into her tight hole. Kairi jumped a bit with wide eyes feling her slit spread open as the appendage moved in and out of her on its own, pumping natural aphrodisiac into her tight tunnel. Quickly with a gasp Kairi backed away, falling to her knees as the short term pleasure made it hard for her to stand, now eye level with Aela's stomach."W-Wow..."She whined, the heat, the bumps and more being too much to handle at first. While she was surprised she was left with unsure lust inside her, part f her, solely her body craving this pleasure, while she herself was still wondering how to handle it, how to take in the new additions to her lover."A-Are you sure..about this love? it seems..like your body..just wants to take me..."
 
(Whichever you want. I'm indifferent ^^)

"I... think you're right. But are you enjoying it Kairi? Because it seems like your body wants it too." The arachne smiled mischievously at the comment. Aela let the human go as she was forced to her knees from the constant impacts. Inch after inch was forcing it's way in with each thrust, stopping for nothing. The tendril pumped mercilessly, intent on not stopping until it reached the girl's womb. While Kairi seemed to have trouble forming words, Aela was just fine, not having the same poison coursing through her veins. She was still clearly deriving pleasure from this, taking deep breaths with each plunge the tentacle made.

"How is this so different from what we'd do before? It's all organic now! It's another way I can express my love for you!" Some of these changes didn't seem so bad, rewarding her with encouraging stimulation and ecstasy. She expected to be compelled to eat people since she looked like a monster, Aela considered this a great alternative.
 
Kairi pulled away from the cock when she fell to her knees, her pussy now empty, drooling and hungry as she sat there, breathing weakly. She listened to how Aela knew she wanted this deep inside, how her body craved more and more of it. while she herself was no virgin, since Aela took it with one of her strapons, Kairi was more than able to handle the thrusts without any pain. but this one was bigger in all forms than that strap on, nothing she had ever taken before. But with the aphrodisiac pumped directly into her hole her body burned with need, her voice in soft whines.

"Y-Yes but..I-It can cum too right? It could..It could impregnate me can't it?"she asked, unsure of any of this. But all while sitting on her knees, her eyes glared at the thick cock.
 
Impregnation? Now that was a word that made Aela's blood boil eagerly. The Arachne seemed to piston into the girl even faster once that word was mentioned. Aela's hands made their way on Kairi's shoulders at some point to prevent escape, to hold her in place. She looked to the ceiling in thought for a moment, biting her lip at the image of a pregnant Kairi and smirking. Somehow though, she knew this not to be true. Not with the tools she possessed at the moment.

"I... doubt it. I'm not entirely human anymore. If anything I seem less human than, anything else. It's likely I've grown incompatible to having a child that way. Genes can't possibly be compatible." She didn't know it, but she was right. However, her new form would remedy that problem soon, but not now. Right now, Aela was content to fuck the brains out of her lover with her new 'toy'.

"Just sit back and relax dear! I'm sure this'll end soon. I think I can feel it!" The mutant was still getting used to all of her new body parts, but at the moment all of her attention was focused on that tentacle cock drilling Kairi. A pressure was forming at the base of her dick, and Aela could feel something begin to move from the pair of balls that dangled below. The sensation left her thrilled for what was going to happen next, and she managed to lighten up on her thrusting. Aela was able to slow the cock down immensely to prolong the feeling of being on the edge. Now moving at a pace of a snail, every touch made inside of Kairi left Aela's whole body shivering. She wouldn't be able to handle this long.
 
No matter how she moved to try and pull the cock out of her it refused to leave her, Aela's arms holding her now as she took in deep breaths, her cunt squeezing more and more. By the time Aela assured her that she couldn't get pregnant she relaxed, seeing the need, the love in her girlfriend's eyes. So with a sigh she relaxed, almost going limp as she let the arachnid move her and hold her as needed to drill her more. The girl moane dhard, kissing her lover intensely as her slit drooled heavily onto the floor and her hips rocked against the cock. She wated this now and she was really starting to enjoy it too. But in the back of her mind she could only wonder how much more change Aela would undergo before being completely finished.

When Aela slowed down Kairi knew she was close, knowing she wanted to prolong the experience. So with a smile she rolled her hips and ground into the cock."B-Baby..do what you want..its been so long since we've touched each other and if..this is a part of you then I'll do my best to please you until we get you back to normal.."
 
"You're a good person Kairi. I'm not sure what I'd do without you. Here, let me thank you." The girls hips bucking toward Aela's cock was enough encouragement to end this. The spidermorph rammed Kairi's ravaged cunt for several seconds before moaning for her release. The orxasm caused Aela to paint her lovera inside with fluids, her grip on Kairi was tightened until the end. The look on her face showed Aela seemed to achieve Nirvana, her head lopsided and mouth left open.
 
The moment she rammed into Kair the girl gasped sharply with wide eyes, her needy cunt throbbing with desire. And when she felt the hot load pump into her she nearly screamed, feeling it fill her insides until it was forced out. The feeling of being filled through her over as she came with a howl, her pussy milking the tentacle cock, squeezing its length as it empty its contents into her."O-Oh god..I-I'm cumming..I-I'm cumming so hard on your...your COCK!!" She whined, slamming down hard before hugging Aela tightly, burying her head in the arachnids tits.
 
It was awhile before Aela could form words. Slowly she straightened her neck and closed her mouth. The pleasure high was fading, and her grip on the human girl lessened, quite a bit. Aela still liked the sight of Kairi buried in her chest, but was now allowing her to leave. Slowly, the penile breeding tool backed out of Kairi's love tunnel, aallowing all of the juices to flow with it.

Her eyes seemed much more focused, her movements more precise. Aela ran a hand down Kairi's hair, wondering just how she was feeling. "You're okay, right? I didn't hurt you did I?" The spidermorph seemed grounded in reality now, sex was the last thing on her mind.
