As many would attest to, there was a lot that could be said about the Last Master of Chaldea. No one was quite sure what sort of history they had as they didn’t exactly talk a lot about it and various rumors only made figuring out the actual truth about their background all the harder to figure out, especially with some rumors being taken as fact even with no real basis. After everything they had been through in Chaldea, things only got even more complicated and the late arrivals certainly had a difficult time figuring out what was true and what wasn’t.
 
In truth, sheer exposure to magical energy, the training of actual heroes and teachers and so many other factors simply combined to give Gudako some ridiculous enhancements as she was met with challenge after challenge and grew, improved, against each of them, slowly becoming more and more of what she was, for better or for worse.
 
All Barghest knew however was that Gudako was an absolute monster in bed to the point that she had to question just what and who Gudako had been before all of this.
 
At first, the Fairy Knight was concerned about Gudako in bed, believing that she might end up hurting her if she was too rough with her. She was supposed to still be human, after all, and very fragile as such, only to be proven quite wrong through repeated encounters as Gudako proved herself to have a truly intense libido and sexual stamina that rivaled and surpassed Barghest’s own, not to mention a lot of dirty tricks to use on top of that.
 
Though they were both “victorious” in the end, it was Barghest who felt like she was completely defeated and conquered as she was left panting, her cock overly sensitive and bursting like a fountain, the very thought of Gudako’s body around her phallus being enough to get her hard even at the worst of times. Even simply grabbing her and slamming her down on her length with considerable force was unable to make the Master stop or regret anything, instead still ending in Barghest’s defeat as she was forced to cum over and over again.
 
Fittingly for her origins, she was starting to feel like she was being trained and Gudako wasn’t even making an obvious effort to do so! What kind of history would she have had to have had to support that sort of behavior and capability? Had she also killed people due to the sheer extent of her sexual drive?! Barghest could never get a straight answer to those questions, leaving her wandering endlessly, even now as she was left laid out against the bed with Gudako resting against her.
 
Gudako had buried her head between Barghest’s breasts, causing a bit of a blush on the Fairy Knight to form and continue even after she nearly had her mind fucked out of her, even more so as Gudako simply continued to adjust and snuggle herself against her hard and impressive body. Every movement further moved Barghest’s cock as well, given she was still deep inside Gudako’s cunt.
 
The Master had simply decided to take a nap, or truly sleep, with her cock inside her and all Barghest could do for a while was let her… She was quite exhausted, after all, having had her balls practically wrung dry by Gudako’s pussy to the point they felt physically empty.
 
Empty enough that, with her general physically and mentally exhausted state, some strange thoughts crossed her mind, leading to her shifting, lifting her hips up and sinking her fingers into Gudako’s ass cheeks, one of them just barely brushing against Gudako’s ass and making the Master moan in a way that continued to be bad for Barghest’s mental state.
 
Lowering her hips back down, her cock slipped out, lubricated by the cum that was nearing the point of inflating Gudako’s lower body, causing Gudako to whine and nuzzle deeper against Barghest’s body without actually moving away or even opening her eyes as far as Barghest could tell.
 
“Hm? So that’s what you want?” Gudako teased with a lustful tone, shaking her ass slightly as she felt Barghest’s cock against her ass, believing that the Fairy Knight was going to thrust up in and stretch out that hole as well with her fat fucking cock… Only that didn’t quite happen.
 
Barghest’s cock went between Gudako’s cheeks, though it didn’t quite hit her hole, instead, hidden to the Master’s sight, it was Barghest’s urethral slit that started to open up, getting larger and larger as the cock was sandwiched between the cheeks, eventually spreading the cheeks even further, nearing a painful point— And then the situation changed.
 
Gudako’s ass was pulled into Barghest’s expanded cock head, slipping in completely and her cheeks clapping closed, further engulfed and held together by the inner flesh of the cock; neither of them had much time to react to that situation either before the Fairy Knight’s hips started working again, thrusting up again and again, pushing against the ass and expanding the slit even further while moving the legs.
 
“What… Are you doing?” Gudako asked in a voice that was more tired than lustful as her legs were lifted up, forced upward until they ended up between herself and Barghest, going up against the sides of Barghest’s breasts and pushing them further against her face, muffling any further comments she could have made even as her entire pelvis was being engulfed by the cock.
 
Barghest made no comments anyway, instead moaning as she fucked herself up, her cock sliding up her Master’s body, swallowing up her cunt, her clit, the tiny nub of concentrated nerves being a surprisingly prominent and obvious feature as it went into her cock, stimulating both of them into barely controlled moans.
 
It didn’t take particularly long for Barghest’s cock to slide up Gudako’s body, starting to engulf her hips and squeezing into her thighs, her ass starting to slide down into her balls. Neither of them was in a state to care about that right now either, aside from the sheer, greedy, tightness that the cock was holding her body with causing the cum that was previous shot out to be forcefully ejected back out, causing an even stranger sensation for Barghest as Gudako started to feel emptier, telling her that something was definitely wrong.
 
It was already too late though, the arms around Gudako’s body as Barghest held her tightly being the only reason why the powerful phallus hadn’t already sent Gudako up into the air for her to properly slide down. Though as Gudako tried to ask further questions and seek answers, she only ended up practically motorboating the boobs being squeezed against her face, bringing even more pleasure to Barghest and prompting her to instead put her hands on the back of Gudako’s head, burying her even further in an attempt to heighten the pleasure.
 
Now only being pushed down on the head, part of Gudako’s body was lifted up off of Barghest’s, Gudako’s own breasts just barely being able to stay against her hot body as the Fairy Knight’s legs started lifting up, compensating for the angle in a natural and instinctive way, allowing her to simply continue as she had been going.
 
With Gudako folded as she had been, there was less length to her body overall, the cock quickly consuming its way to her breasts and knees simultaneously, the sheer width of the body entering Barghest’s body nearly sending her into another orgasm as Gudako’s ass and crotch was dumped directly into the recovering supply of cum within Barghest’s balls.
 
All Gudako could do was wiggle, trying to free herself in whatever way she could, the cum feeling warm against her ass, slowly trying to flood back into her pussy, to fill her up as if she was just another container for it and little else; all the while however, she was simply motorboating Barghest’s breasts, making them jiggle around her head, the soft yet firm flesh smacking and reverberating against her head while her own breasts followed suit, stimulating the insides of the cock in ways that the Fairy Knight hadn’t even thought possible.
 
Ultimately however, Gudako did manage to get her head out from between the breasts, in part due to the unstoppable cock still consuming its way up her body. Her face was wet, her breath short both due to a lack of air and sheer buildup of lust that she couldn’t deny no matter how hard she tried.
 
Her life was in danger, but by the damnable gods, the full body massage that the cock was giving her was a whole different level of pleasure that would have left her wet and aroused if not for her overpowering survival instinct and the fact that her pussy was already flooded with cum that eliminated any sign of arousal she could even produce beyond a lustful expression on her face.
 
She tried to struggle, tried to squirm, but with the cock pulsating against her body, against her lungs, she couldn’t really get any words out and with only her hands being free, there was only so much capacity for struggling in the first place. She could still activate the Command Seals, but Barghest was too far gone to understand or see what was going on while Gudako was unable to actually voice any sort of command, leaving the Seals effectively useless as well.
 
Barghest’s face meanwhile was locked in concentration and edging herself even as her hands pulled and teased on her own breasts, still pursuing and following the highs of pleasure regardless of Gudako’s situation, who was effectively forced to watch it for a few moments, watch the sheer pleasure on Barghest’s face as the cock climbed up the length of her neck and got closer and closer to her face.
 
There was an indescribable taste against Gudako’s lips as the cockhead engulfed them, one of her own sweat combined with Barghest’s own, combined with cum, all of which slowly went into her lips, rather unintentionally further being licked up as Gudako tried to get out some sort of final words, some sort of final attempt to get her to— “Stop!”
 
But it wasn’t enough, her mouth being engulfed as well, the cock approaching her nose, assaulting her with the smell as well, closer and closer, her eyes being the next to go, the world turning dark and soon enough her body being reduced to little more than her arms peeking out of Barghest’s hard cock, her body still being outlined against the tight skin and flesh of the cock, only some of her lower body further expanding and pushing against the bottom of her balls.
 
Gudako’s hands continued to flex, trying to figure out some way to get away from here, trying to reach for something that could help, something that simply didn’t exist, while Barghest’s own grasped her cock, starting to stroke it instead of just relying on the thrusting of her hips and twitching of her cock to get Gudako down.
 
Barghest’s balls grew larger as the body inside her cock went down, Gudako’s ass making them jut out further and further out even as her hands fully disappeared, two middle fingers flipping Barghest off with the last bit of motor function Gudako could manage in the outside world, the rest of her body being pushed down by the hands stroking the cock.
 
She was forced into a fetal position inside the cock, regaining some measure of movement of her limbs as she was no longer folded over like she had been for the past few minutes. Naturally, she tried to kick and punch and scream, but she couldn’t even make Barghest’s skin shift, instead just massaging her from the inside and causing the Fairy Knight to cum, leading to cum flooding up Gudako’s ass, pussy and mouth before being shot out the cock and covering Barghest’s body.
 
The final orgasm well and truly exhausted her however, Barghest’s eyes closing, her hands falling to her side and cock growing soft even as her balls were left expanded with the whole size of Gudako’s curled up and struggling body.
 
It was a furnace in there, as far as Gudako was concerned, even as she carefully swallowed the cum that had rushed up her throat, the rest of the cum that was slowly joining her in filling up the balls feeling particularly hotter than she remembered it being…
 
o.O.o.O.o
 
What followed was a mystery to even Gudako. She struggled for a while longer, putting however much effort she could into it until she simply blacked out, either out of exhaustion or simple dehydration due to the sheer heat of the balls… She wasn’t really sure.
 
All she knew was that after some time of struggling, she found herself in a different place, a rubbery prison that she quickly ended up escaping, finding herself… Naked and in her room with the nearby clock implying that it was either the next morning… Or she was back in time to the morning of the same day. She could never be sure.
 
What she could definitely be sure of however was the fact that the “rubbery prison” was a condom, which certainly had implications as to what actually happened to her…
