More often than not, this is the way you asume the gender of someone you meet (only when you are unsure whether or not she has a bulge under her panties though): the more curves she has on her body, the more likely she was born with a pussy. And if she possesses a big frame with more muscles than fat under her skin, then there is most likely a cock dangling between her legs, and a big one too. Sejuani is indeed a good example: one of the most muscular in the League, only second to Illaoi. Breast size is a bit below average, though they fit perfectly on her well toned body. Every limb she possesses are weapons, including the boneless one: a weapon meant to break everything that stops her from putting a bun in the oven. And perhaps, also to break everyone.

People who stay somewhere in between – ones who have their fair share of curves - are difficult to make a guess. Though reality often proves that, the bigger her breasts are and the softer she looks, the smaller her cock is (or the more likely she has a womb). Shemales can’t give birth, thus they can’t breastfeed, so there isn’t a point in having big breasts, wouldn’t you agree?
Exceptions are quite rare, like one in a hundred. Ashe, for example, who has more than enough fat on where she needs, and a bitchbreaker good enough to make a dozen whores crawl at her feet, begging to be the first to get violated. Ahri – despite being the one closest to the term “perfection” - doesn’t count, for she had been a male fox who stole a females’s essence. And neither does Sona, but she is special in a different way: she has almost no cock at all, but in return she looks more like a female role model than most females themselves.

An androgynous lacks every good stuff above. Breasts? None. Ass? Error 404. Dick? More girl-ly than dickgirl-ly, if she has one that is. Vagina? Most likely. Most girls don’t like them – they are fragile and so are their miserable cocks. Neither do strong shemales: they don’t have enough meat nor their holes are stretchy enough to withstand even one good fuck, much less a double penetration. Anal is difficult as well. Females are meant to be impregnated, so they have wide hips by default. An average shemale, even though theirs might be smaller, can still swallow a huge sausage with their lower mouths. An androgynous – being female or not – can’t take a cock more than 3 inches in girth, simply because their are too small. Thus androgynous whores are mostly favored by the average – females and shemales alike - those who like to take the dominant role, but do not have what it takes to actually pull it off.

Sex in public is, of course, not allowed. And half-dark alleys are exactly the kind of place somewhere between public and private. When ecstastic moans and the sound of flesh smacking on each other are gone, cumstains and used condoms – sometimes even torn panties – will be found. That is the aftermath of people falling in sex at first sight, or a whore getting paid for a quick shot. For some people, having passengers witnessing how good they are at fucking others into submission is as important as the pleasure in sex itself. 

Katarina was a sucker for that, and she sure knew how to abuse her position - not as the General’s daughter, but as the deadliest assassin in Noxus, and arguably in the world. It all started with a feast that was made to honor her merits in Noxus’s glorious victory against Demacia: A shemale general – one as old as her father – overtly disrespected her and challenged her to a fight. After losing miserably, the general was thrown onto one of the tables, her pants torn before Katarina fucked her asshole. Raw. Everyone present – the guests, the servants, even her whole family - was able to see how the angry expression turned into one belonged a submissive bitch in heat only after minutes. And when the young assassin finished cumming, the so-called general was already too far lost in pleasure.

Katarina could never forget the eyes of those around watching. She saw fear. Admiration. Arousal. And she knew they all wished to replace the bitch on that table. Those thoughts were tasty. And so Katarina repeated. Now there were girls who learned the taste of her cock scattered everywhere in Noxus when the ruthless one developed a liking for them when they passed her by on the streets. None of them had any problem with that. The females even wished they would get pregnant, though unfortunately for them, there was success so far. And there was one problem: none other could make them feel as debased as she did.
Katarina had earned everything to rise above them all. With the rate of her climbing the ranks and fucking the citizens, they thought the sadistic assassin would make this whole country her own brothel in no time. And so did she.

Yet she learned to give up on that ambition.

Katarina had never liked her youngest sister – Cassiopeia Du Couteau. Unlike the rest of the family, who proved their worth through blades and trophies, Cassiopeia preferred to sit in the dark, pull the strings, and let her puppets do the dirty work. Well, nothing’s wrong with that. That is a kind of strength too. However, she relied on it too much. She thought anyone can be controlled, manipulated. Hmph. The only reason she hadn’t been dead yet was because the deadliest assassins were all Du Couteaus. Katarina didn’t trust her. Thus there was no sisterly love either. And when she heard that Cassiopeia had returned from Shurima only to lock her new lamia self in their family’s crypt, she couldn’t care less. Pathetic weakling.

On that night, Katarina returned home after finding some good fucks in a tavern. She was spent, ready to hit the sack, until she noticed something was off: the crypt’s gate was open. Someone finally decided to get some fresh air? Hah, good for her. She then turned around and continued to where she was going to. Unaware that while she stared at that gate, a serpentine figure slithered into her room. 

As Katarina closed the door and unzipped the black suit, she smiled at how perfect she was. Being outside mostly when the sun has gone down gave her a fair complexion on a well trained body, neither muscular or lithe, just fit, greatly emphasized by the black tattoo running on her abs. Her breasts were firm and only average in size, but for an assassin, those were good. Her nipples stood upward, as if expressing the arrogance in her nature. Still, they weren’t the brightest spots on her body. Katarina had quite wide hips, which would have made her look like extremely fertile had she not have a cock. Her was covered by tight leather suit specially designed to fit her perfectly, leaving nothing to the imagination. One of the reasons why people liked to walk behind her, and she took pride in that. When she pulled her pants down, her dick flopped out and hung freely, having been exhausted after ejacuating seven times in a row in that tavern debauchery. And yet its curved shape was still visible. She wasn’t the most well hung alpha predator out there with only 8 inches in length, but it was the shape that made females crazy and shemales broken. Katarina would hit and crush their prostate with every thrust, forcing them to their hands-free orgasm and milking them dry before flooding their flesh pipe with her superior swimmers. 
She grabbed it with one hand and flung it up and down, right and left. She played with it, squeezing it from the base, made it ooze out a big droplet of precum, which turned into a string, slowly reached the ground. She smiled at the picture in the back of her mind: earlier in the tavern, one of the sluts using both hands to stroked her cock, while staring at it like possessed, with bliss in her eyes.

With this cock, i can get all the bitches...

“With this cock, you can get all the bitches, big sissss.”

"The fuck!?" Startled, assassin turned around. She was fast, but already one step behind. A giant snake body wrapped around her from breasts to toe in less than a second, immobilizing her completely.

Casiopeia showed her face to her big sister. Her taloned hands, like snakes, slithered on her sister’s face and breast, examining the pale skin, and the anger in those emerald eyes.

“But dear sisss, you will always be my bitch.”

“Cassio-? What the fuck are you doing!?”

"Ahhhh hah hah hah, you look even more beautiful when you're angry." Cassiopeia licked her lips. With a long, forked tongue of a snake. To Katarina, her sister's sultry voice was utterly disgusting. That bitch was not even worthy being a servant in her house, let alone being her sister. And that bitch dared to talk, to play with her like this? "You're not funny, fucking failure of a Du Couteau. Let me go!!"

"KHARRRRRGHHHH!!!" In the blink of an eye, Cassiopeia tightened her tail's grip and rushed her head right in front of her sister's face before letting out an atrocious roar. Katarina had no idea, but she would have been turned into a statue had it not been because her view was completely covered by the younger sister's corrupted mouth. The younger sister's tongue wasn't the only thing on her face changed by the spells of Shurima. Her jaws were too. Unlike human's, the joints of a snake's jaws are located at the back of its head, which allows it to open its mouth wide enough to swallow preys as big as itself. However, her face would still look the same under normal circumstances, like when she talks and eats. Eating small food that is. 

When Cassiopeia loosened her grip back to before, Katarina felt like her heart had stopped for a second from the lamia's hair-raising act. She quivered in fear as she stared at Cassiopeia's throat - a slimey abomination from flesh and drools, long fangs dribbled with venom. 

Wait. I, quivered in fear? Me?

Only now Katarina realized she was more fucked than she had thought.
"Hehhh hehhh hehh, sorry, big sissss." Cassioepia giggled after closing her jaws. "I'm still learning to control myself, so please, try to refrain from testing my patiencccce. But you know what, there are so many ways i can kill you with this new body. I can crush all of your bones, insssstantly. I can swallow you whole and digest you, ssssslowly. But those methods would destroy your beauty. Maybe you can look at me in the eyes like real lovers, then i'll petrify you and place you in the middle of my room. A true massssterpiecccccce."

"Oh, no, sisss, don't be scared." The lamia smiled almost innocently. "There's no way i'm going to do that. I love you." She began to carress Katarina as her older sister was shaking and sweating like crazy. She was afraid. She had known what Cassiopeia had been capable of. Now she knew what Cassiopeia was capable of. She had thought that someone like her younger sister, one who never had tasted defeat and took such a devastating defeat, would never be able to lift her head up again. And so she had let her guard down.

Cassiopeia's arms wrapped around her sister as she embraced Katarina and spoke in a carefree tone, which was even more horrific. "And now... i'll make you mine."

The next thing Katarina knew was having two deadly venomous fangs plunged on her neck. She screamed in terror and agony. Or at least, tried to. Her voice couldn't get out. Cassiopeia giggled and withdrew, uncoiled her serpentine tail. Katarina would have fallen like a tree had Cassiopeia not caught her and brought her to the bed.
Now she realized that her body was completely paralyzed. She could only move her eyes, and she used them to stare at the figure above her as the lamia started undressing herself. 

"Sisss, you would have been dead had i used all of my fangs and venom. Took me a lot of time to control them. And a lot of specimens too. Why do you think i went out anyway?" Cassipeia giggled as she remembered the poor criminals who she had hunted earlier. Well, they should be out cold for a few days. More than enough time for someone to discover and bring them in. Or maybe fuck them first. Some of them were quite fuckable.

But they were not here type. She already had her eyes on her all high and mighty big sister.

"Ohhh, This was killing me. I haven't bought any new bra yet after returning from the trip." The younger sister took off her two-numbers-too-small bra and tossed it aside, freeing her breasts, almost twice as big as Katarina's. 
Then she untied her belt, and threw it on her sister's noses, carefully not to block her eyes. The disgusting stench caused Katarina's head to swoon. Cassiopeia could tell that, judging by the way her sister's eyes moved around like crazy. "Smells lovely, doesn't it?"

"Now, sisss, take a good look." After throwing the belt away to let Katarina concentrate on the show, the lamia placed her fingers around her crotch. There was a vulva. Or so the assassin thought. Until Cassiopeia held her breath, and that part shifted. It opened.  
A meat rod started sliding out. The head was flat and deformed, and Katarina had never seen one before, but with logic, this should be how a big snake penis looked like. It was smooth and pink, as pink as the insides of a body, giving you the thought that this is either new-born, or well protected and rarely used. In Cassiopeia's case, it was both. And the surprise didn't end there. Another head was pushed out. It was another. Compared to the former, which Katarina estimated that should be as thick and long as her forearm, this one was smaller. It looked mutated too, but it still retained the characteristics of a human cock: the shaft was darker and had foreskin, and the crown was rounder. Finally, the base of both cocks slipped out, along with two big pairs of testicles, red in color and so plump it looked as if the four were dragging the whole genitals down low. The balls belonged to the bigger cock were also bigger. Now that the base was revealed, it became obvious that the smaller one was the original Cassioepia had got. The other one was the result of the spell, being grown like a branch on the left side of her crotch. And yet it outgrew its sister.

One would ask how all of them managed to fit inside that slit. Well, her hips were extraordinarily wide for a reason.

Katarina certainly didn't like the development of this situation. But there was nothing she could do, except from watching the lamia playing with her cocks the same way she had done minutes ago. Cassiopeia slithered on the bed, around her big sister, and slapped the bigger cock on her cheek. The cocks were both slimy, naturally lubricated by some kind of fluid the sheathe excreted, which would help her getting her way with unwilling preys. With the other hand, she spread Katarina's mouth open to its limit and pushed the crown on the lips. "Hmm, too small. Can't fit this one, as expected. Oh, i have an idea! Maybe i'll turn you into something similar to me, and your mouth will be able to spread wide enough to fit my cocks at the same time! You like the sound of that, sisss?" 

Of course, her eyes were saying "Fuck no!! Stay away from me, you psycho!!". 

"Mmmm." Cassiopeia moaned excitingly as she slowly stroked that cock. Soon cum started to leak out and dropped into Katarina's mouth. "This cock is quite an extraordinary tool, you see. It's very easy for it to cum, it can give you a bowl full of my seed only in half a minute. And when it ejacuates for real, heh heh, things can get a little... messsssy.". The assassin had never tasted cum or juice before. She just loved spraying cum on the whores' faces she claimed because in her mind, once someone gets marked by cum in public, they would be as low as trash. "Hmmm, come on, drink up! Don't be shy. You can drink to your heart's content, i have so much stored. Oh, maybe you will become like me if you drink enough?". Katarina of course didn't want to become like her, but the Cassiopeia was getting hornier with every second imagining what it would be like for her vicious sister to be a lamia, her hand was stroking faster and faster.
"Ah, how am i so thoughtless. My precious cream belongs to somewhere else, right?" She stopped stroking and realized that the assassin's face was red. With the paralyzing venom, Katarina could barely breath. And she could neither spit out or swallow a mouthful of cum. "Oops, sorry! I'm so sorry, sssissss! Let me help you!". She lifted her sister up. In her panicked mind, Katarina thought Cassiopeia was going to let the cum flow back out. However...

... She spread the assassin's jaws to its extent again, then pushed her smaller cock straight down. The natural lube, combined with her cum and Katarina's saliva made things go swimmingly. Cassiopeia moaned animalisticly, savagely moved Katarina's head up and down, oblivious about the fact that Katarina eyes were almost white and tears rolled down her face. While her throat's relexes were still on, they were by no means enough to object the lamia's rampage. Every time the lamia went in, the crown hit her esophagus painfully. When it came out, her throat was pulled, making her body feel the need to vomit, but then the intruder would come back in. While her tongue was so numb from everything going on that she couldn't taste anything, her nose wasn't helping. When she was filled, her throat was blocked completely and that gave her the need to breath. But when she could barely get a breath, there was only that nasty reek to inhale.  She was forced to breathe in the smell where it came from. And if the belt's stench was disguting, the crotch's stink was horryfying. It was obvious that Cassiopeia didn't bother cleaning her genitals. Well, judging how troublesome getting her cocks and testicles out of the slit was, it is only reasonable, isn't it? And she had a sick thought: only her big sister - her lover, was worthy to be used to clean those parts. Starting with this smaller cock. 

So she just literally used her sister's mouth to wash it all the way clean. There wasn't that much pleasure from deepthroating Katarina, but who cares? She was putting Katarina's mouth into good use. The mouth of the most fearsome assassin in Noxus. Admired and feared by anyone. They would do anything to be claimed by her. Yet now here she was, taking her sister's fuckhole in her thoat. Powerless! Inferior! Obedient! Submissive! Cassiopeia moaned louder and louder in ecstasy, her tail swung from side to side as rapture embraced her existence. Then with one roar, loads after loads of sperm poured down into Katarina's guts like a waterfall. And yet thanks for the venom, Katarina's body didn't show any reaction. The only difference between her state and a dead meat was that she was warm.

"Hahhhh... That was refreshing. Thankss, siss!" She shook the assassin's head. Her eyes rolled up and not moving at all. "Hey, wake up! The night's still young, you know. There's still plenty of fun for ussss to enjoy. Ahhh, you're not listening. How rude. I'll go on before you then."

Cassioepia rolled her sister's body over, and spread that juicy ass with her thumbs grabbed on Katarina's asshole, and slid her slippery tongue in. It was longer, smoother and forked, but was still as thick as a normal tongue. The tightness of the virginal lovehole couldn't stop it from going in. It slapped around the walls of flesh, tasting, exploring. She even spread her jaws to its limit, allowing a few more inches of her snake of a tongue to go in, reaching past the colon. Her sister was so tasty, she could get addicted to this! Finally, before leaving the delicious meathole, she turned, twisted her tongue from sides to sides, trying to lap as much saliva as possible. The lube would probably be enough, but just to be sure. Because it was gonna get stretched very, very wide... 

She grabbed her smaller cock and circled on the O-ring, smearing the mixture of lube. The meat shaft was still recovering and hadn't got as hard as it could be, but it should do the trick. Katarina was both tight and completely irresponsive, so Cassiopeia had to do all the hard work. She spread and pushed. Then spread and pushed more. The tightness was tenacious without Katarina's help in opening herself, but finally the tip went in. She moved it out a bit and in some more, stimulating her body to produce more slime. "Mmmm, sisss, you're so fucking tight i think i could cum." She started to move. There was still not much pleasure she could feel, for her cock had just cum and now it was aching from being forced to get erect in such a short amount of time. But that was a good thing, because with this incredible tighness, she would have ejacuated had her cock not drained before this. And there was no way she was gonna give her sis a premature ejacuation. Not in their wedding night, oh no.

The lamia could feel it. After being... augmented, her senses improved greatly. Katarina was opening herself more and more with every thrust. Looser. Softer. Like a meat getting tender under a mallet. Cassiopeia knew that... her sister was ready. To accept her love.

She pulled her smaller dick out and slapped the bigger one on Katarina's asscheek, admiring how beautiful it was. It was as hard as a rock, more than prepared for this. She had been waiting for this moment. She had wanted her sister for so long ago. But only after being turned into this, she found the resolve and the means to act. And everything was all according to the plan. Now the last step was to repeat what she was doing, only with a bigger cock. And a looser hole.

Cassiopeia gasped at how good it felt when she managed to get it all inside. The hole was perfect, like it was created for this sole purpose. As if it was a living thing, trying to squeeze whatever her testicles had just from the tightness alone. Finally the moment has come. She lied down on her sister's back, embracing her. Katarina, all the while, still couldn't move her body at all, but the lamia could feel the hot, ragged breath. With the smaller cock, the pain was bearable. But with this serpent of a cock, her ass was on fire. Hot tears rolled down on her face only for Cassiopeia to lick them clean as she leaned her cheek on her sister's, carressing her. "Ah... I've taken my sssister's anal virginity. No... You're not my sssister anymore. From now on, you will be my love." She closed Katarina's lips to place a kiss on them.

"I love you... Kat."

"Hufff...!" Was the only sound the mighty assassin could let out in her breath as the lamia started fucking her for real. Everything was burning, but she could feel the head of that thing clearly. It was big, and unlike the rounder head of the smaller cock, it managed to leave marks in the back of her mind everytime it went in and out. It reached places even Cassiopeia's tongue hadn't. Her love button was pounded continuously, causing her cock to ache from erection and orgasmed for the eighth time in a row tonight. And yet it was not allowed to go limp. It was painful. It was pleasant. How the monster stretched her, and how her body shifted to accomodate. How more and more of her interior was intruded, and how she learned to feel the parts of her body she couldn't feel before. How it was bruising her prostate, and how it was jerking her off without touching her cock.

How much she despised the person who was raping her, and how that person was driving her insane with newfound sensations.

Cassiopeia had always dreamed for this moment. So many times she had fapped with this vision in her mind. And this? This felt like a thousand times better. "Hahhhh... can you feel it, my love? I'm going... *huff...* to cum... *huff...* inside you. If only i could make you pregnant. Dammit, it would be perfect. A baby in your womb would make this complete. Take it, Kata! Take my seeds! Get pregnant... from your dirty asshole!!" Katarina couldn't pay attention to those words. There was too much going on. And yet it felt as if everything stopped, allowing her mind to experience what it was like to have torrents of sperm rushed into her bowels. Shots after shots, fired with such force she could feel the first ones clearly as they painted her insides white, before filling her full with the creamy liquid. It felt so warm. Almost numbing. The lamia didn't stop fucking while she was cumming, making Katarina even more of a mess inside. Wetter membrane meant faster thrusting. And cumming felt so good she couldn't think about anything other than getting as much pleasure as possible before this precious moment gone. Make their first time complete and whole.

"Fuck, that was even better than i had expected." Cassiopeia gasped for air satisfiedly as she pulled her limp cock free in one go, causing Katarina to feel like her too sensitive asshole was turned inside out. She felt it when the lamia had to use force to pull out the crown, leaving the deformed hole gaping for a second.

And in the next second, she was flipped up and her young sister wasted no time to fuck her mouth with the now-erect smaller cock. "You are so good, Kat. When i used the bottom hole of yours i miss how good your top hole felt wrapping around me. Good thing is i have two cocks."

The lamia didn't allow her to rest. After fucking her mouth with the smaller cock, the bigger one would have recovered and her asshole would get fucked again. And just like that, the cycle repeated. When the sun finally rose again, Cassiopeia had already finished her 5th round. The bed was a mess. There were cumstains everywhere on Katarina's body. Even though the venom had lost half of its effect, Katarina still had no strength to move her limbs. She was not even fully concious. Half awake, half asleep. Even for a well trained assassin, both the physical and mental stress put on her was too much to handle. It felt like she was trapped in a never ending loop, but it seemed like Cassiopeia finally decided to take a break. 

"Oh my, didn't notice it's already morning. Mmmhhmm, i still want to do it more, but it's not like you're going anywhere, right? Let's get some rest."
But Katarina didn't catch that. With no cock forcing her to wake up, she slumbered in seconds.

***

[A few hours later.]
When Katarina woke up at noon, her mind was sober. Everything around her was disgusting. Cum everywhere in and on her body, and on the bed. It was also the only thing she could taste and smell. Cassiopeia was sleeping soundly behind her, wrapping her arms and tail around Katarina tightly. Well, of course escaping wouldn't be as easy as running straight out of the door. But there has to be a way. If this go on any further... i may not even have the will to fight.

"Still looking for a way to escape? You hurt my feelingsss ssso bad."

"Wh-what...? How?"

"Oh, did i forget to tell you that my senses were highly improved? I was woken up by how fast your heartbeats got. Amazing, right?"

Okay, now that was new. Katarina didn't know what to do anymore. "You look amazed. I still have so much to show you, if you let me. But save that for later. You're craving for my cocksssssss, right?" Cassiopeia climbed on top of Katarina, letting her cocks lay on her lover's flat stomach. The assassin could feel how hot and erect they were, how they were throbbing in need, waiting to remind her how hard she had screamed in her mind last night. 

"N-no... Stop... Let... me... go... or..."

"Oh, what are you going to do, darling? Let's face it. You know you can't win. You can't escape from me. I can play around with you like a snake playing with a rat. When you almost manage to get out of here, i'm gonna give you another dose of venom. And then i would continue enjoying your company. How does that sound?"

"N... No..." Katarina tried to stop Cassiopeia from spreading her legs. She held her hands on her sister's head, trying to push her away from sucking her erect dick. The dick she had been proud of. Now it just looked like children's toy, even when compared to Cassiopeia's human cock. The lamia let go of her cock with a suckle on the crown, licking her lips while staring at Katarina whorishly.

"No...! Please...!" Her sister aligned the reptile genital in front of her asshole, and pushed. "No!"

It hurt so much, Katarina had to spread her asshole against her will. And that was all Cassiopeia needed to shove it all in.

"Hhhnngghh!" The assassin gritted her teeth to endure the pain. But when the rapist started moving, it died down. Gradually, replaced with the last thing she would need right now: Mind-blowing pleasures that could make her cock orgasmed. She saw how her belly shifted, a buldge moving up and down, pushing her toned abs outward. The visible sign of her body being demolished. She knew her mind was, too. She desperately crawled on the bed sheets but she couldn't overwhelm her captor's grip. She tried to look for something. Something that could get her out of this mess. But the poundings would just pull her thoughts back to where they should be: experiencing how good Cassioepia was at fucking her into submission. Katarina turned away, hiding her face behind her hands in shame. What she had done to the others, now was being done to her. And the longer it was happening, the more she changed. Adapted. She didn't want to enjoy this. She was forced to enjoy this. 

Erotic moans started to escape her mouth when her prostate was pummeled. She tried her best to hide, but it was no use.

That was all the arousal Cassiopeia needed to go at full throttle. "Now you're more honesssst, Kat. I'm so happy. That's right. Moan for me, my love. Scream my name!"

No... I don't want this... But this... this feels... so good!

*knock* *knock*

Huh?

"Excuse me, Mistress Katarina. Are you in there?"

"..."

"You haven't had breakfast and lunch today. We thought you were tired, so we have brought your meals here."

"..."

"Mistress?"

Cassiopeia looked at the door behind her back, and stared back at Katarina. She obviously showed no fear of this situation development, and on the contrary, it seemed she even liked where this was going to. "Come on, be a good Mistress and answer her. Oh, maybe she can help you! Just yell 'Call the others! Call my father! Cassiopeia is assaulting me!' and they will get you out of here! You can prevent me from catching her! Come on!" She taunted while still fucking Katarina, even harder than before.

"Mistress?" *knock* *knock* "Are you sick?" There was concern in her voice. "If you're in there, please excuse my intru-"

"No! I'm okay. Just... resting. You can... *cough* leave them out there. I'll take them... later." Katarina tried to hide the gasps with coughing, as it was too difficult to speak fluently with a dick ravaging her asshole.

"I understand. And one more thing: the Master told me to ask if you have seen Lady Cassiopeia, or know where she went to. Do you?"

"Oh my, you're going to cum? In this situation? What a ssslut!" Cassiopeia whispered mockingly as she felt Katarina's cock twitching. 

"*cough* *cough* N- *cough* No. *cough* I don't." Her body trembled from head to toe as she orgasmed.

"A-Are you sure you're all right, Mistress? Please wait, i will call the family doct-"  

"No!! J-Just go away! I want to *cough* be alone." 

"Then i will take my leave. Sorry to have disturbed you."

When the sound of footsteps gradually gone, Cassiopeia also stopped pounding her lover. "What's wrong, Kat? It sounds as if you're scared of them knowing that i've assaulted you." 

"Sh-shut up."

"Oh, right, i forgot you're not the talkative type." Cassiopeia then forced the assassin to get up while she lied down, with her cock still balls deep inside. She grabbed Katarina's hands and placed them on her stomach. "Few wordss, many deedss then. Ride my dick like a good cowgirl and keep that assss nice and tight for me, will you?"
Katarina didn't know how to respond. But the lamia just continued pummeling her. Only that this time, she did it half-assedly. Katarina grew frustrated. She wanted the pleasures she was given before. This just made her insides itch. So she started moving on her own. And before she knew it, she was riding Cassiopeia while she closed her eyes and moaned whorishly. That's right. I should have realized sooner. I don't lover her. I don't agree with her. I'm not going to give her what she wants. But i will get what i want. And i want this. This feels... so fucking good!

"Ohhh! I love you the most when you're honest! Come on, i'm close! Give it more effort, and then i shall reward you!"

"Ah... yes... Cum... inside me...!"
Katarina no longer gave a shit about anything else. Right now the only thing she cared was pleasure. And how to get more pleasure. She moved her ass like possessed.

"Yes, that's the spirit, darling! Here it comes!"

Her vision exploded into stars, and everything went vivid as andrenaline rushed to everywhere in her brain, filling her existence with rapture. Cassiopeia didn't lie about being able to cum buckets. Katarina felt like she had been filled another big meal again. So much cum. So warm. So full. So happy. 
Without any strength left and with Cassiopeia's cock growing flaccid, Katarina had to get off, gaping for air. But when the lamia stood up, she couldn't help but staring...

"Hmm? What's with that look? Ah, you're expecting me to make you suck my cock again, right?" Hearing those words, Katarina snapped out of her daydream and turned her eyes away awkwardly. But then she remembered that she didn't have to run anymore, not after going this far. So she clumsily grabbed it and licked it like how a good girl should. Even though the smell was awful, the taste was surprisingly good. The slime was slightly sweet, the precum bitter and salty, making her mouth water.

"Mmmm... Yessss... so eager to pleassssse..."

Katarina was tending to Cassiopeia's genitals, licking everything clean: smegma, cum and slime, both fresh and dried. Then she felt Cassiopeia's hand on her cheek, motioning her to stop and look up. They looked at each other in the eyes.
"I love you so much, Kat."
"I... i..."
"Ssssshhh. You don't have to answer me right at this moment. I'll be waiting. But if i can be selfish, then when there's just the two of us, i'll call you Kat. And you will call me Cassie. No one else has to know about our relationship, alright?"
"..."
"... All right. Cassie."
Cassiopeia pulled her up to give her a deep kiss, and hugged the love of her life to sleep.

[Later that day...]
Katarina was sleeping well. Cassiopeia would have slept some more too, but this wasn't her room. And there was something she had to do. Someone she had to meet. She returned to the crypt, and closed the gate. Even when it was open, no one had given it a visit. Boring place anyway. 
And yet Cassiopeia knew she was not alone.
"Oh, just on time! I thought you forgot about me." There was a sultry voice in the darkness.
"Hehh, how can i? I may not look like it, but i'm a girl with manners. Something you don't have, grandma. Forcing my darling to answer you when she was cumming? That was very rude." The lamia giggled.
"Well, what can i do? A grandma like me loves seeing kids enjoying themselves. It makes me feel young again. But more importantly i just wanted to make sure the potion worked."
"Oh, it worked like dark magic. You have my eternal gratitude. Now, where can i find our girl?"

[Two days ago, Family Du Couteau's crypt]
Cassiopeia had been living in here for a few weeks. The first weeks were spent disgusting her new form, and mourning the aristocratic life she lost. Then she learned to accept what she had become, and how to put her new body into good use. One of the new things she could do was to taste the air with her tongue. And she knew very well the smell of the crypt she stayed in.
Until one morning, she tasted an unfamilar smell. Something that couldn't be here, was here. A sweet, fragrant aroma of roses in a rotten place.
Still, she pretended nothing was wrong. She went around, acting as if she was doing works, until she found out exactly where the source of that smell was. It led to a statue. 
"KHARGGHHHH!!" Cassiopeia fired a blast of acidic venom from her throat. The statue's skin was immediately corrosed, revealing a real person being burned by the noxious liquid, hands covering her deformed face. Cassiopeia grinned at the intruder, who was screaming in agony "You're gonna tell me who you are, and who sent you, before i melt your fucking skull off!"
And then the figure vanished. Into thin air, along with the gracious fragrance. Leaving only a pool of her venom on the ground.
"What the fuck!!?" Cassiopeia slithered back, unable to comprehend what just happened.
"Oh my, that's quite impressive." That voice was from behind her back. She aggressively turned around and fired another blast, but this time there was nothing. And then there were laughters coming from another direction.
"Show yourself, coward!"
"I intend to, but that's impossible if you keep spitting on me like that. We are all civilized humans, right? Don't worry, i'm not here to harm."
"Fine then. But don't fuck with me. Or you're going to be my breakfast."
Chuckling from the shadows, a figure emerged like a magic trick. The first thing Cassiopeia noticed was that this person had a fancy way of dressing. There was a black coat with wide collar covering her back completely but it didn't make her look mysterious, because she wore little on the front, showing her extremely pale skin, suggesting that this person had always stayed in the dark. What she wore could be compared to a set of seductive looking lingerie one would only wear to arouse their mate in bed. But the most remarkable thing about her was her eyes. They were almost like Cassiopeia's herself. Evil. Intrigue. Cunning. Malicious. And she felt like those eyes could see right through her. Cassiopeia knew what type this person was: the "If you treasure your life, never stand against her." - type.
"A pleasure to meet you, Cassiopeia Du Couteau. I am LeBlanc of the Black Rose."
"You're lying. The Black Rose is just a myth."
"You're not the first one to say so, and won't be the last, so i'm not going to bother proving it. But i believe you can see that we are kindred spirits. And you think i will try to deceive you with a blatant lie?" Well, that much was true. 
"Then what the hell are you doing here? What could 'the great Black Rose' want from me?"
"Ahhahaha, nothing much. We just heard that a Du Couteau had returned to her home as a monster. And as the Matron of the Black Rose, i had come to see for myself. To see if your existence could affect Noxus." She spoke with a smile, something Cassiopeia could not interpret. "But now that i have seen all that needs to be, i feel that the rumors were exaggerated. All i can see is a powerful beauty, though short-tempered."
"Pft. Cut the act. That maybe the reason you're here, but it's not the reason you show up. I can tell that you could have hidden away from me. But you chose not to. Tell me why."
"Mhmm hm hm haha. Smart girl. I guess i can be more honest with you. Right, i wanted to have a chat with you, because i felt that we can make a contract. I can give you-"
"No. Don't try to tempt me. What do you want?"
"So cautious. All right. I want you to capture a person. I already have information on her whereabouts, but she's not in Noxus, and i'm too busy right now. She's strong, but after watching you these days, i believe you can overwhelm her easily. Especially because she refuses to kill. How does that sound?"
"Tasty. Who is she?"
"Ever heard of the name Riven?" LeBlanc gave Cassiopeia a photograph of a white-haired woman.
"Riven? She's alive? Heheheheh, interesting." Oh, pretty girl. "But why me? Surely you have many more better choices."
"Because they are all related to the Black Rose, and i don't want any of them to know about this. The Black Rose still thinks she's dead. They aren't looking for her. I am. So, do you accept?"
"Depends on how good your offer is."
"A chance to make Katarina yours." Cassiopeia was astonished when she heard that, but only for a moment. Right, of course she would know. The lamia had masturbated with both cocks screaming her sister's name as she peaked for so damn many times. LeBlanc grinned implicitly as she took out a small potion. "Drink this. Wait for one hour, and then... fill her with as much of your body fluid as possible, which i think won't be a problem for you. And then she will grow addicted to it. She won't be able to live for a day without receiving your lovejuice."
"Sounds too good to be true. Is the effect permanent? Is there an antidote?"
"I created this myself, haven't made any antidote, and it should last long enough to give you two a happy life. So i wanted to answer 'yes' and 'no', but there is no such thing as absolute certainty, my child. Which is why i'm just calling this 'a chance'. Grab it or ignore it, that is your choice."
"..."
"I ssssay... we have a deal".
"Very well then."
