Akeno lost her patience, and starts taking matters into her own hand - Chapter 2 - Allnight9 (2024)

Chapter Text

Rias couldn't comprehend how long she has been nearly suffocating under Akenos balls by now. It felt like an eternity for her. Since she had nothing else to do, but sniffing up Akenos endless supply of Ball musk, she tried to think of a way out, however with one obstacle: The bonds fucked up every single chance to escape, and her mind was clouded due to inhaling the wet-making pheromones for who knows how long.

The temptation to just give in and start licking those humungous balls was strong. But she still had Issei on her mind, deeply rooted in the depths of her brain. Akeno really had a long way to go to reach those depths in Rias' mind. But when she does... she won't just slowly pick these thoughts up and replace them with her own goals. Oh no... she will pierce through every single brain cell with the might of her bitchbreaker, and rearrange Rias' whole Identity from a "proud-gremory-diva" to a "big-futacock loving busty bimbo slave"

*

When Akeno stood up from her comfortable position, Rias was relieved to breath in some fresh air again. Not for long though. Akenos thick, trained pronounced thighs stopped mid-air in a squatting position, she lowered her hand in which she hold her book, looked down at Rias, and gave her little toy an enchanting smile "you look so cute covered in my ball sweat my king, huhuhu, I just wanted to tell you that I am done with the first chapter, so there are 9 more to go. Keep it up, and don't forget to stand still, I feel like your breath tickling my balls is enough, to make me climax. I assure you my king: we will both go through this together. Now let's not waste any more time! Let's make ourselves comfortable and let me get right back to reading!"

How was she supposed to take on a comfortable position, when she was strangled by Akenos huge orbs? She knew it. Rias knew everything Akeno said was literal provocation, But somehow she kept falling for it, and kept getting mad at her. No matter how ridiculous this situation seemed to be. Rias was the one in charge. The moment she meet Akeno for the first time, she was her subordinate, her servant, her right hand, and now the exactly same subordinate (except for the newly acquired thick, long vein-riddled 2-feet appendage, that she didn't had before) was sitting on her face? her heart filled with pride and resistance: "I will bite off your balls, if you put them near my face again!"

Akeno wasn't really bothered, not even slowing down her descending hips, quite the opposite: she took Rias' resilience with glee and grounded her orbs against Rias' face in a teasing way: "my-my. your aggressive nature really is tempting Rias, it makes my balls fall head over heels for you. can you feel my little swimmers squirming inside?" she asked, while rubbing her humungous balls on her face: "you can try to bite them, but don't start crying if you lose a tooth in the process", with that last statement she went back to reading her book.
Rias thought about it: "can testicles really be that hard? they look so soft... or are Akenos balls harder because of some silly magic?.. or maybe because of her nature as a fallen angel? No!" she thought, she was just trying to intimidate her. She opened her mouth determined, took a mouthful of ball-skin between her teeth (which was not much, due to its size) and bit down... or tried to at least. Her teeth ached, it felt like biting into hard cement, therefore she pulled her teeth back again, glad that she didn't actually lose a teeth like Akeno warned her about.

When the wad of sperm landed on Rias' pubic area, she cried out. Mostly was muffled due to Akenos sound absorbing pillow (her balls). the outcry sent Vibrations through Akenos Balls and forced another big dollop of precum out of her cock straight onto the same spot again. It was hot, Rias thought, so hot, that it felt like it was burning her skin. She feared in her musk-baffled mind, that the temperate might represent how virile the sperm is. She hoped it had nothing to do with that. She squirmed under Akenos weight, trying to get it off, it tickled her pussy, and made it drip wet even more.

Akeno did not realize why Rias was squirming so much, until she took a better look. The thick lump of her pre-cum flowed down, about to reach Rias' labia. Akeno reacted fast, she leaned forward, unintentionally grinding her balls even harder onto Rias face and with a fast *WUSSSH* wiped the creamy substance away. She wiped off a drop of sweat of her face: "huuu~ that was close. I haven't told you yet, but my sperm is really virile, and it has... seductive effects, when it comes in contact with the inside of a pussy. to my regret, just Like my cock, my sperm cells seem to have a mind on their own. Once reaching the opening of a fresh pussy, especially a virgin one like yours, uhuhu~, there is no way, that a woman would NOT get pregnant. I have experience, thrust me. Some even tried anti-baby pills afterwards, but without any effect." She didn't know if Rias did even hear her, but when Rias stopped her winding-around, taking a big "gulp", that resounded on Akenos testicles and making them vibrate again, Akeno set on a smile, knowing Rias understood her very clearly.

"Is that even humanly possible?" Rias wondered in her baffled mind, not even trying to act ashamed of Akenos carefree fact about her virginity: "This fat-cocked girl seems to be more masculine (at least if you only consider her Dick and its features) than all men on this cosmos combined together." Although Akeno wasn't a human. It was still frightening her. Not until 2 days before, Rias thought that Akeno was a virgin, and that she wanted to steal away her Issei, and now? now she was asking herself how many women she had fucked already and left them with a baby-belly. a few? dozen? hundreds? thousands?!"

Rias thought it was the best, to just stop the struggling, and live with it, until Akeno finished reading her book. Akeno seemed really immerged in reading it as well, so it might not take very long... Sometimes she just started laughing, probably because something funny was happening in the novel. Rias almost thought, that Akeno had forgotten her under her huge balls, but she convinced her from the opposite, simply by mashing her balls up and down, left and right a few times, while letting out small moans and grunts.

Under these circumstances Rias couldn't really sleep, her brain even flooded her mind with possible "solutions", to make this whole situation pleasant for both parties, but Rias didn't dare to consider those "solutions". Her brain started to betray her, whispering in her ears to just give in, and play along Akenos game.
While Rias' racked her Brain about her possible possibilities, Akeno was none the wiser. She was too busy reading her novel.

Time passed by, her Pussy dripping like a broken faucet now, her brain felt like it was breaking in two pieces, and suddenly, she just couldn't control herself any longer. Rias opened her mouth, that was soaking wet just like her Pussy, she slowly emerged her tongue, licking her lips in shameful anticipation, and... took a lick... She instantly withdraw her tongue, the taste salty and sweat at the same time. It felt divine, and Rias brain asked for more. If Akeno found out that Rias was in heat right now, she might use it to her advantage, and who knows what other plans she had in store of her... but Akeno didn't react, Rias thought. Her throat was aching, and her depraved brain in need of more of that musk, the smell alone was not enough anymore. Akeno wouldn't mind, would she?

She advanced her tongue again and started licking slowly and tenderly, making out with Akenos balls like a lover would to its partner, she closed her eyes, only concentrating on the divine taste of the source of her undoing... until Akeno shrugged, lifted her booty a little, lowered her head down and to the side, due to her huge cock obscuring her vision and looked sternly into Rias eyes.
the sadist, that should be feeling joy in this kind of situation, since her plans were finally starting to take effect on Rias, tilted her head down, and looked down at Rias with utter disgust as if looking at a useless, disobedient slave.
Rias had mixed feelings about Akenos reaction: her brain told her, that Akeno would enjoy it, she should be looking at her with nothing but affection, but now... "What am I thinking about?!" - she blamed herself, now with her brain free of Akenos musk "What have I just done?!", she blushed, turned her head away, too ashamed to meet Akenos gaze.

Akeno analyzed Rias' act, she was certain of what her musk could cause, but so fast? Akeno was only sitting on her face for about 6 hours. She was disappointed... she expected more of her King. But she also couldn't let this opportunity pass, she has been waiting too long for that day... that month...
Her expression turned back into a smile with her eyes closed, a grin plastered on her face, taking on angelic features... fallen-angelic features... People are never able to muster what that smile meant or what intention she had, whenever Akeno put it on, even Rias who has known her longer than anyone else. It could be meaning everything: hatred, love, disgust, care... "I really appreciate your desire for me Rias, but please let me finish my book first, before we get to the main event." "...I di- didn't d- do that on purpose, I..." she thought for a second to get out of this situation and looked into her eyes: " I- It felt like something was stuck in my throat so I had to cough!" she replied with not much hope for sympathy though, well aware that she was talking nonsense.
"So coughing means licking around other people's balls for about a minute?" Akeno countered, looking deep in Rias eyes, knowing exactly well, that she was lying.

Rias averted her gaze in shame again, being aware that denying it would be useless. When no answer came, Akeno sighed, shook her head. Usually the ultimate sadist would not miss the opportunity to provoke Rias with ironic statements with her usual "uhuhuhu-laugh" or "my-my". But she was really absorbed in the book, especially since the current chapter was so exciting.
She sank down again, taking her proper position on Rias face, before saying "This will be your last chance, stop those insolent actions. I am trying to hold this bad boy in his cage as long as possible, and your just starting to throw treats at him. If he managed to escape, it will be your fault, if I can't control him!"
A shiver run down her spine. no, she would definitely not like to experience, what would happen if Akenos "Beast" would be freed of its cage.
She calmed down again, and hours after hours passed. She couldn't believe it, but her Brain was once again suggesting her to become better acquainted with those heavenly full balls, but she tried to hold on...

about 12 hours passed now, and the balls didn't stop rumbling and churning till the first second she took over the role as a seat-cushion, working overtime to produce as much swimmers as possible. And to Rias' regret, they kept growing and growing, making room for all the swimmers yet to come and therefore obscuring Rias' vision and overshadowing her face in even more of her ball-sack. That also meant, less air, and more musk for Rias, which had taken a serious effect on the poor girl. Her eyes turned half-lidded, she couldn't focus, couldn't get a clear mind, the musk was taking a toll on her poor weak mind, more intense than ever.

In addition to the hot summer weather, the temperature of the room was rising over the span of the last 12 hours due to Akenos musk and pheromones clouding the room. And the fog had no way to escape, due to the closed doors, and windows. The 2 girls and Akenos pheromones were sealed off from the outer world. But that didn't only effect Akeno and Rias, who were getting hornier and hotter every second.

The hot temperature had an effect on Akenos vein-riddled testicles as well. The skin getting soggier over time, hanging lower and lower, starting to accentuate the 2 huge orbs within, but still not daring to leave their comfy position on Rias' face. That made it only worse for her, the room was hot enough, but with what little space was left for her, it felt like a hot sauna on her face.
Akenos ball-sweat was clinging to her face, making her pony stick to her face as a result. "All those swimmers... waiting to be released inside of me... I wonder how they taste... I just have to take-" she opened her mouth "-another-" withdrawing her tongue "-taste..." and started taking a tender lick. That Ball sweat was making her addictive. "Am I to blame?" she thought "She started all of this in the first place, and how am I supposed to hold back, when the only thing my brain is able to inhale is her disgusting *lick* dirty *lick* sweaty *lick* salty *lick* sweet *lick* addictive *lick* ball musk...*lick*."

Her brain was too stubborn to consider all that though, and wanted to take another lick of her sweet balls. But when her mouth didn't open up, even though her brain gave the order through her nervous-system, Rias realized, what that earlier snap of Akeno achieved... Akeno just sealed her mouth shut. Rias started squirming again, breathing was hard enough under Akenos ball-press, but now her main oxygen-way was taken away from here, causing her to start sniffing deeper and stronger with her nose, filling her brain with more and more of Akenos must. When Akeno didn't react to Rias' struggles, she ceased it, instead trying to control her breath, taking long deep sniffs of air (let's say 10% air and 90% musk) and tried to calm down.

She thought in her depraved mind, that nothing seemed to stick. Her Issei-loving-self lost the battle against Akeno by nearly losing a teeth, and surprisingly her cock-desiring-self lost the battle as well, by pissing Akeno off, and getting her mouth shut as a consequence.
Only thing left for her now was waiting for Akeno to finish her book. She had no sense of time though, the only thing her brain was capable of doing in this situation was fighting over the control of her body, deciding how their host: Rias, would act once Akeno has finished her book. Her heart obviously remained faithful to Issei, while her brain didn't want anything else, but to get used to her cock-milk and ball musk for the rest of her life.

After about another 12 hours of Rias nearly being suffocated, the ball musk of Akeno now deeply rooted in her brain (never forgetting the smell again) Akeno stretched her arms over her body, grinding her balls a few more seconds against Rias' face and stood up. She rose her hips with a heave, went off the bed, to the table looking at the timer, "25 hours, 7 Pm now, not bad I have to say for myself", she placed the timer on the table again, before restarting it. She turned around again, and walked towards Rias, wondering how her little toy was feeling after the 12 last hours of their last visit, but only took a big *gulp* when she saw her, and starred at her in awe.

When Rias looked like a beautiful crimson-haired woman with perfect proportions before, she was now definitely the opposite. Breathing heavily and blushing, her beautiful azure-eyes half-lidded looking up at the roof, not even realizing, that she got to see light again, still taking big sniffs, as if she was still being suffocated, her crimson hair clinging to her face, due to all the ball sweat. Her whole facial expression, as if she was in pure bliss right now. For Akeno, that was a much better Rias, much better than the old Rias, that was acting all tough and strong, caring more about others than herself. The only things that were missing now were rolled-over eyes, the tongue slipping out in an beautiful ahegao face and her hands caressing her shaft while she was sucking and worshiping Akenos huge meatstick. Her cock took a big "gulp" as well in its own way: by pulsing repeatedly up in the sky, trying to run away from Akenos crotch, and dreaming of taking its proper position as a part of Rias' body, or better, inside of Rias' body.

Akeno stood still for a few seconds, disturbed by the sight, the great thrilling ending of her novel not interesting enough any longer. Her goal was set, her smile disappeared, giving a short glimpse of her real self that she held back for the last few years. Her whole existence was screaming for that red-headed slut now. She took another deep breath, closed her eyes, and put on her usual smile again, not daring to lose her composure now, only 1 day into the session. She grabbed her dick at the base, rising it up and *thump* smacked Rias on her beautiful proportioned tits, making them wobble for a few seconds, before they went back to place. She was torn out of her day-dream with a whimper, her left breast aching, her eyes focusing again.

Akeno had a great feeling of amusement, well aware of Rias' mental state. Rias looked around at first, trying to focus her mind, taking in deep clear breaths first. That's what she hoped for at least.. The whole room was obscured, as if they were in the middle of a cloud in the sky right now. The smell did not get better in any way, but at least her inner fire kindled again, she locked eyes with the girl, that brought her into all this, furrowing her brows, the defiant look back on her face again, that Akeno used to slap into unconscious just yesterday.

Akeno wasn't impressed at all, even if Rias was acting resilient, she was 1 step closer to her goal. Getting Rias addicted to her ball-musk already was a good thing that would allow her control over the situation whenever the girl got cocky again. She tried to stick to her schedule, she had planned everything perfectly, and considering Rias' current internal crisis, it won't even take as long as expected to break her mind, or so she thought... She just couldn't hold back her laugh at Rias' sight, a small gap visible in her usual composure. It wasn't her usual provocative laugh. THIS insane laugh really came out of her heart, giving another unintentionally glimpse to her true self, it was depraved in all ways: "How long are u planning to give me that stupid look you slut?"
Rias was shocked, that was not the Akeno she used to know. It's like a wild animal has taken control of her. She starred at Rias with awe, like a predator, hiding deep in the high grass, about to catch its prey. By looking into Rias' fearful eyes, Akeno realized, that she has lost her usual facade, she cursed herself for that. It shouldn't be that kind of rape, she thought. It was still rape, yes, but she wanted to break Rias with pleasure, and not with setting her in fear.

She cleared her throat, putting on a smile again, which made Rias even more anxious, there was something wrong with Akeno, she thought. "huhuhu, I am sorry my king, the sight of your beautiful smooth face made my dick get the better of me. Now. The first session is over, even if we had to face some problems-" she winked at Rias "with someone controlling her manners... I am happy to announce, that session 2 can now start. Do you have any suggestions or wishes? Maybe you want to drink something, eat some foot, take a shower and get all that sweat off your face?"
Well aware of Akenos spell, that was shutting her mouth, Rias looked angry at the sadist. Akeno acting all surprised and perplexed: "what? no wishes? Alrighty then~, if you want me to decide, then I am happy to oblige my king~. But don't expect me to go easy on you, I gave you a chance after all".

Of course Akeno knew how to start the second session, her dick has been asking for attention an annoyingly long time now, so she will grant it some attention. "I think you already got well acquainted with these things here" she looked down at her balls, the blood-filled veins pulsing faster than her heartbeat. If looked closely, u could make out the little swimmers squirming inside in anticipation, hoping to escape the prison, that most of them were caged in for a month now "my-my... did they grow again?" she asked dumbfounded and tried to grab one in her hand. When she was able to fit 1/4 of it into her hand before, she now only got about 1/6 of it into the palm of her hand. Her Scrotum was in odds with the size of her Balls. The balls inside did grew without respite over the last month and especially the last 24 hours, not caring about the poor skin, that was holding the 2 hooligans inside their cage. The skin tensed and stretched agonizingly wide around her huge orbs. The scrotum was figuratively and literally being deprived of its space, not having the same possibility as her balls to expand furthermore as much as they wish, it was stretched to its limits, resulting in pronouncing her huge orbs inside even more now.

"oh-my... they are really calling for their release. they must like you a lot" she removed her hands of them after giving them a solid squeeze: "NGGGHHH~, to their regret, they already had their play time with their little toy already, now it's time for their daddy to have fun" with that, she took a hold of her cock, which grew even more over the last 24 hours, the veins more pronounced, due to the increased blood-flow. This time she needed 2 hands , because one was not able to encompass the big mass of meat any longer. She directed the tip over Rias' face and started swinging it up and down, slow and precise. Her dick was the only thing in this room, that Rias had respect off, for one single reason: that it managed to knock her out cold yesterday.

It came down and up. DOWN: starting to obscure her vision, and UP: giving her eyes more sight. The pendulum like movements got faster and heavier, it went higher up, but therefore lower down, close to Rias face, she felt the slipstream hitting her face, until with a *slap* the cock started to reach its destination. Now with Akeno having more momentum, her dick sometimes hit her mouth, her nose, her eyes, forcing them to close, it was just varying its impact spots, trying to remind Rias who was boss here. Rias had problems holding onto her defiant look. She felt humiliated again, just like yesterday, when it slapped her into oblivion. She thought about her current situation. She just felt stupid, looking defiantly, when a big fat cock was slapping her in the face. She was feeling like some circus attraction or something. But Akenos cock didn't think about Rias that way. It paid her respect... in its own way at least. It was happy to finally get some attention again. Her balls got a great massage for the last 25 hours, while her cock had to stay untouched, throbbing, streaming full of blood, without being able to do anything against it.

Akeno was starting to have fun again, her cock pulsing unrelentingly, while she smiled wickedly into Rias' eyes, not daring to miss one second of them, while they slowly turned to fear and hopelessness.
she imprinted the exactly same defiant expression into her brain, to remember it for later, when she managed to turn Rias into a cock-addicted babbling mess, that didn't feel fear or defiance anymore, only awe, lust and love towards Akeno. Even if she had to shred her every brain-cells to achieve her goal, She would not relent.

After a few more dozen slaps, she ceased her movements. She took a step up to the bed again, her cock swaying to and fro, casually slapping against Rias' tits and grinding her chin.
Rias was giving her an ashamed look of anger. non-verbal communication was the only thing left, since her ability to speak was stolen from here. "hey, don't blame me now, it's hard to control a 2-feet stick that can bend and bow into every direction."
She was straddling Rias' body again, looking her in the face while taking a few steps back. Once she reached the perfect distance, she stood still right over Rias' lower abdomen. Rias waited patiently, obviously worried with every movement Akeno made, not really understanding what was going on in her mind.

"This should be the perfect distance" she said, before she lowered herself down on a kneeling position again, with her cock tip know exactly hovering a few inches on top of Rias' head. Rias was baffled, still staring at Akeno, or more like the cock obscuring her way, with confusion on her face. "oh come on. don't look at me like that. I was just going to take a better position. Standing too long, with tits this big can cause serious back-problems. you of all people, should understand that" she said while slapping Rias on her tits with her cock a few times. Rias started to squirm again: mainly, because her tits ached. Akeno does not seem to realize how heavy her cock is, it's like a freaking hammer pummeling down at her. Secondly, from Akenos current position, her heavy testicles rested comfortably on Rias' wet, dripping pussy. Compared to last time, they had a much closer look at their future home now, and were squirming joyful and happy in anticipation, tingling Rias' outer labia while sending light sensations up her brain.

When Rias still didn't came to a halt with her squirming, Akeno ceased her movements in her own way, by leaning forward, taking a hold of one of Rias' nipples and twisting it in her tight grip. Rias wanted to cry out loud because of the pain (and a little pleasure), but she couldn't, instead a tear ran down her cheek. Akeno licked her lips, her sadistic side showing off: "you done know? can I continue please? The longer it takes, the more you have to suffer. And since the outcome is crystal clear, wouldn't you like to fall head over heels for me as fast as possible?" She gave her a few teasing cock-slaps on her face. Rias finally stopped her squirming, she still looked defiant at Akeno, but Akeno didn't care. She sat back between Rias' thick thighs at her groin, and kept on slapping her dick against every body part its 2-feet radius could reach.

this whole ball & cock teasing didn't really benefit Akeno in any way. She could just slide back, ram her Dick inside of Rias and end it all in an instant. But then there would be no fun in breaking someone so quickly, thought the busty sadist.
This was a once-in a life time chance, and she would enjoy every single minute of it. And that's by starting off with teasing her balls and Cock first. She wanted her cock to be as hard as steel, and her balls, to be churning full to the brim, before starting with the real fucking.

Rias didn't really feel well about all the cock-slaps on her face that made her brain rattle inside. Like yesterday, she thought she would lose her conscious again if Akeno kept bashing her without a care for her wellbeing. But today wouldn't be that easy. Before her mind managed to black out - indicated by her eyes slowly losing focus and closing down - Akeno relented her cock slaps on Rias' head, and gave a few hard blows against her tits, sometimes twisting her Nipples, as well as groping Rias' breasts and squeezing firmly, until her knuckles got swallowed up by her soft tit-flesh, causing Rias' to wake up wide eyed out of her slumber and squirming around in pain. Akeno kept repeating the process. This time she did not want to give Rias any sleep or rest by letting her pass out. A small time-span to collect her mind would only rekindle that stupidly annoying defiant attitude of Rias.

This went on for hours, light bruises showed up on Rias' face and her tits felt sore, due to the unrelenting slaps, squeezes or nipple-pinchers. Her eyes lost focus, she felt light-headed. She was close to pass out so often, but Akeno wouldn't allow it.
Akeno was proud of herself, she kept the treatment up for a long time. Although her dick was doing the literal opposite. It pulsed and throbbed, feeling blue balled for too long, as if it was the one, that got tortured and not Rias. Since it was a part of her body, it also had an effect on Akeno as well, so she thought she would give them a little reward.

She ceased her slapping which went on for hours, and drove her hips back a bit, letting her dick slide down over Rias' face, to the top of her breasts, then she applied pressure on top of it to make it stick to Rias' torso before she slid her cock back and forth on Rias' body. Her dick too big and too heavy, therefore pushing aside her breasts, while her cock made its way through the valley of her tits. Akeno just stared in blue-balled awe at Rias' defined abs, a light six-pack visible, hidden under her silky smooth skin, that consists of not too much fat, only there, where it counted.

When Akeno thought about it, Rias wasn't really keen on sports, and that didn't seem to matter at all. It seems as if all her consumed nourishments did only seem to gather on 3 centers: her breasts, her hips, and her rotund juicy bubble butt, (which Akeno didn't even manage to make acquaintance with, since she arrived). These were the only spots that could gather as much fat as possible, without looking bad at someone's body. While Akeno looked like she was in heaven, letting out small grunts here and there, while her balls gave huge throbs, Rias looked at her in disgust. She had enough self-confidence to realize that she had an angels body, but that body was supposed to be only for one guy, and that was her love, Issei. Akeno on the other hand only saw it as her own property now. "uhhh~" she moaned, " this body is out of this world, I wonder how good that pussy of yours will be... or how your mouth feels. You know what... I think it's about time anyway, the next lesson won't be as pleasant for you, as it will be for me. Let me say it like this: the more you suffer, the more pleasure I will probably have uhuhu~"
"time for what, what are you planning now you-" Rias thought, still not able to speak, until Akeno snapped her fingers "- stupid ugly looking black haired sadist" these last words, came out of her mouth though. She should be happy to speak again, but under those circumstances, and for what Akeno said just seconds ago, she knew her ability to open her mouth again had another value this time.
"fufufu, I am granting you the ability to speak again, and you just start using it for babbling non-sense?"

"tsk, tsk" she chirped in annoyance, "why do you have to make everything so difficult..." She rolled her eyes, bend forward, and squeezed Rias nose shut, and waited patiently, a smile plastered on her face, looking eagerly into Rias' eyes, while lining her cock tip up with her lips. Rias' eyes widened in surprise, her face slowly turning from red to pale. She would rather suffocate to death, instead of lowering her standards and take such a disgusting thing inside of her maw. But her body had other plans... When a body stands on the brink of death, it takes its own measurements to survive, ignoring the host's wishes and ideals, and Akenos steady-growing smile indicated that she knew that. Before she felt herself losing consciousness, her mouth opened abruptly to take a deep breath... instead it took a fistful of Akenos mushroom-tip inside.

Well, it tried at least. She only got the half of her tip inside Rias mouth, due to the large size, and Rias' mouth being too small. That was one disadvantage by having an humanly-impossible sized dick, Akeno thought. It was too big to enter human orifices, human anatomy just wasn't made to get drilled by such a huge meat-stick. This wasn't the first girl that Akeno had taken advantage off, though. After a few girls, which she only saw as test-subjects, she found out that rough force was the only way that helped her in those situations. Rias' mouth was opened impossibly wide, her jaw aching. Her eyes wide in discomfort peering down horrified at the cock tip, which was trying to squeeze its way through her mouth. "it is hot", she thought "It really is as hot as fresh-forged iron", she gazed up to Akeno with plea on her face "MHHH! MHHHH!!!" she tried to somehow signal Akeno that her jaw just might break.

Akeno was too busy forcing her way inside though, her smile disappearing, she squinted her eyes, grit her teeth in focus, wiggling her dick in an attempt to loosen the too small hole. Slowly millimeter after millimeter entered, "uhhhh~" she groaned, "I am al...most..." *SLURP*, her cock tip barreled in Rias' mouth with such a force, that it hit the back of her throat, straight knocking at her Uvula. A muffled *glur-rrrk* came out of Rias' mouth. "...there...." Akeno groaned, swiping sweat of her forehead. "What a tight fit you are" she said relieved, sitting down again, while her dick was still burrowed in Rias' agonizingly wide-opened mouth: "HMMMMHH-MHHHHH!!!" Rias voice was muffled, eyes still wide open, her tongue was smashed flat against the underside of her mouth. Squirming and letting out incomprehensible sounds was the only thing she was able to do with that fat cock-tip in her mouth.

"Congratulations-" Akeno applauded while catching her breath "you did it, I am really proud of you my king, fufufu" now that the overly sized tip overcame its first obstacle, it could carry on with the next step. Akeno waited patiently, staring at Rias with expectation. Both staring at each other's for a few seconds. Akeno smiled, tilted her head to one side, while Rias starred at her wide eyed and protested as much as possible: "MHHH! MHHHH!".
"hey- come one now, He won't be sucking him by himself." "MHHHH-MH-MHHHH" Rias tried to communicate with her, but Akeno was none the wiser, she took hold of her chin in her hand, and was lost it thoughts. She acted dumb: "hmmmm. could it be, that you're not able to move your tongue, due to my delicious cock tip taking up all the space in your mouth?" Rias did not like, how she stated that, but gave her a "Mhhh..." in confirmation. It was hard to demonstrate what she wanted to say, but Akeno got the message.

Still in thoughts, her sadistic side was overtaking again: "Well, I get your point my queen, but that is not enough attention for my dick. you only managed to fit the tip in, which is like 4 inches, there are 20 inches left to fill you up with... unless you... OHHHH!" she acted like she got a flash of inspiration, and snapped her fingers. Rias felt relieved that Akeno finally showed some empathy for her "- you want me to move on my own?! are you sure?" Akeno asked, acting all perplexed, but still smiling at Rias. "MMMMHHHh! MHHHH!" was the only answer she could muster. Akeno swayed her hips up and down, forcing her cock to follow the motion, as well as Rias' head, which was stuck on its Bell-end. Her head was forced to imitate Akenos cock movements, therefore: nodding up and down. "my-my, you're really eager. But if you insist... I don't reject your decision. you're my king after all...", she chuckled in delight.

She stood up, her dick holstered save inside of Rias' mouth, and bend forward. She took a hold of Rias' head on each side, she tried to lift it upwards towards her, but the bonds were in the way, so she changed her mind. If she wasn't able to use Rias' throat as a masturbation-tool, she just had to fuck her face instead... Rias meanwhile followed her movements with panic in her eyes.

Akeno decided to take a few careful steps forward, (every movement she made looking comical due to her hefty Dick size). Her dick was bending with her movements, instead of inserting itself inside Rias' throat (who was really glad about that fact). Her Hands hooked around Rias' armpits as she took hold of her, picking her up with inhuman strength, and threw her towards the headboard like a toy, until Rias whole back stood straight against the headboard, a 90 degree angle at her groan, as if she was sitting upright on a chair.

Akeno, who was being happy with the outcome and also about Rias' wide eyes filled with anxiousness, stood proud on the bed, taking on a provocative pose: her legs apart, straddling Rias' body. Akenos hands were on her own hips, looking down at Rias like the pathetic, little slave she was now, while Rias looked up at her, with fear rooted deep in her eyes. Every expression she made just ended up looking comically though, because of the huge piece of meat inside her mouth that stretched her mouth. Akeno made a few test-movements, wriggling her hips from side to side, testing the grip her mouth had on her meat. Her cock followed her movements like a snake, same as Rias' head, who was really scared for her life right now, a small piece of her just wished that her jaw would break off, and her misery would end right here, but (sadly) she was in good hands, Akeno was taking good care of her...

After a few wiggles, Akeno was sure Rias' mouth had a tight grip on her cock-tip. She tensed her legs on the shaky bed. Rias' attention was attracted to Akenos thighs now. she took a big *gulp*: toned muscles concealed Akenos thighs. If there wasn't so much fat on her thick thighs, you could consider her legs as strong and proportioned as that of a body builder.
"how did I never noticed these thick, water melon-breaking thighs?!" a shiver went down Rias' spine. possible thoughts about how Akeno got them appeared in her mind:
A: she just had them forever, Rias just never took notice of them.
B: she got those thighs while fucking other females, because her huge cock's length required really long thrusts.
Both A and B were really unlikely, because Rias has seen Akeno naked a lot of times before, and was pretty sure, that they were not there before.
C, the probably most likely explanation, and the most fearful in Rias' mind: While Akeno was at home the whole last month, she performed a very effective workout session every day in order to be able to fuck Rias non-stop for the next month without getting tired. "gulp..."

She averted her eyes from Akenos thighs to Akenos face and her smile, that did well in hiding what she was thinking right now, and what she did the last month alone in home...
Akeno took a small step forward, her Cock bending with her movement, she took a firm stance on the bed, tilted her hips back, until her throatbreaker was as straight as a spear, directly targeted at Rias' face, and *WHAMS" in a blink off an eye she thrust forward . "MHHH- GLLRRKKHH" a guttural gag coming from the back of Rias' throat. Akeno could feel it literally strangling her cock, but sadly for Rias, and gladly for Akeno, steel is more stable than flesh, therefore her throat bulged obscenely to accommodate the meat (or steel) stick, while it barreled its way forward. She gagged again and again, her throat trying to get rid of the oversized intruder, that was clogging her airway but it wouldn't prevail.

to Akenos regret, her cock didn't make it in with one smooth stroke as she had planned. At the looks of Rias' throat, it only made its way down to her collarbone. She was really upset with herself, as well as with Rias' too tight throat, which didn't manage to take in everything.

She was so busy being upset about her failure, that she didn't realize, that Rias was suffocation on her dick: "GLRKHHH MHHRRKKKK...MHHHHH.....Glurk......." Only when the gagging sounds ceased, she took notice of Rias as her mind was slowly entering heaven. She thought fast, snapped her fingers to cast a spell. She bend forward and gave Rias a few slaps on her cheeks to wake her up.
To Rias demise she abruptly opened her eyes again: "mnnhhh..? mnnhhHHHH, GLLRRRRK" She still felt as if she would suffocate, her brain calling for air, but she somehow didn't suffocate... She looked around the room in panic, her eyes darting around, until she met Akenos gaze: "my-my, don't just scare me off like that. I really thought I lost you right there" Rias' gagging continued "MHHH-gluuuurk-".

She finally did it, her whole Cock was stuffed into Rias' esophagus.
Her lips were now kissing the base of her cock, Akenos balls were heaving on top of Rias' breasts.
Even Akeno, the sadist, that (almost) always hold her composure, let herself go a bit, savoring in the feeling of having such a divine cock socket all for her own. "Whoa..." she said, petting Rias head "We finally did it, that's not only a first time for you, huhu, I never managed to fill a girl up to the base before." She wriggled her hips a bit, trying to loosen up Rias' throat to make her next deed easier and smoother. Rias was still losing her mind, her whole esophagus now working over time, convulsing the inner muscles to force that too large cock out. But the only thing it accomplished was tickling every single CM of Akenos 2-feet long bitchbreaker, giving her an experience she never felt before in her life. Most pussies she fucked before couldn't even come up to that feeling. She might even end up coming if this kept up.

"MHHH~, now let's not get to cozy here, don't want you to think of me as a quick shot." "...quick shot?!" Rias thought "she has been neglecting her dick the whole last month, and was teasing it for the last 2 days, how can she call herself a quick shot?". All that didn't matter though when Akeno took a firm hold of Rias head and started to pull her dick out agonizingly slow, savoring every pump in went through its way out. Her dick didn't want to leave the warm comfy stomach yet, but it didn't have any say in this situation. Akeno was the boss after all. But It didn't leave without a small farewell gift.

While the dick contracted out of her comfy stomach, it was being compressed by Rias' esophagus, and therefore squeezing it firmly, causing a small amount of pre-cum (for Akenos standards) to travel through her compressed urethra, down into her dick tip. And before the tip re-entered Rias' esophagus, the thick viscous strand of pre cum lost its hold of the dick tip and said hello to Rias' stomach acid, giving her a sample of what will surely be overflowing her stomach soon enough. Rias felt how the thick appendage slowly contracted out of her body. Akeno took her time though, she looked down onto the place, where her Dick and Rias' airtight-sealed lips met. She watched in awe, as every single vein of her dick slowly withdraw out of her slick throat, coated with her salvia and her throat slime, giving her cock a smooth shine to its appearance, which made it look even more frightening now. "mmmfffff-gluuuurk-cough-cough-GHLURK~" were the only sounds that came out of Rias, while the never-ending shaft kept withdrawing.

Her face was a total mess, Sweat plastered her hair on her face, salvia dripping out of her mouth, her nose running unstoppable, and her eyes narrowed shut, while tears run down her face. When Akenos tip got stuck in the entrance of the throat however she started to panic: "NHHHGGGGHHH-MMMMFFF~", it was positively stuck, Rias was so close to free air, and now that stupidly thick mushroom-tip persists, not wanting to leave.
Akeno concentrated, she wanted to get out as well. she felt blue-balled and wanted to get out as well: "my-my... if this keeps up, -NHHHGG~- I might blow up, apologize my king, this might hurt a little" She changed her hold on Rias head, now holding onto her forehead, instead of her back and with a firm *PUSH*, she pressed against it with all her force, with one last "gluurrrr-BWWAAAAAAAAHHH!" Rias was finally free. Akeno fell backwards clumsily on the bed. Her Dick standing tall and aiming straight towards the ceiling, bobbing around until Akeno stood back up "uhuhu this was really dangerous. Are you alright my king?"

Rias couldn't answer, to busy taking fresh air into her lungs. Akeno pulled herself together, stood up with a big groan, until she glazed at Rias' slutty face. Her arms still bond against the headboard, her huge tits heaving with every deep breath she made, her crimson hair a total mess, and her face sweaty, her nose running and her eyes tearing up.
Her Dick throbbed and shoot a big strand of pre cum forward as an response. she was a beauty already, but the slut-suit fitted Rias even better, thought Akeno. She really had to pick things up a notch, she didn't want to waste any of her semen somewhere else, but inside of Rias' body. It was her destiny, to take in every single drop of those eagerly aching balls, thought Akeno in her depraved mind. "Uhhh. please... why do you have to be so sexy my king~" she said while giving her Dick a few squeezes.

Rias looked up to Akeno as well, after being able to catch her breath. She knew everything she would say, ends up turning Akeno on even more. She had no options left therefore didn't dare to talk back to her, her facade didn't look defiant any longer either, not even sad, but not broken as well. It was as if she had accepted her fate, and just let it happen. But Akeno didn't like it to be that easy, there was no fun if the sadist couldn't break her toys properly. She wanted Rias to cling onto hope as long and hard as possible, until she can break it all into shreds, by inserting herself into her pussy. THAT should be the icing on the cake.

"are you also asking yourself what Issei might be doing right now?" Rias picked those words up and looked wondered, what was she planning now? didn't she get all she wanted from her already? "I definitely think that he is thinking about you right now, missing you just as much as you miss him. He's probably on the beach right now, with hot chicks around him, but not daring to give any of them attention, because he only loves you" Rias thought about it, she did not understand why Akeno was doing that, why she would try to ignite Rias' fire back inside of her again, but it worked. Rias put on her usual diva-face, and frowned "-and I will do the same. I will hold onto this misery until he comes back. 28 days left, try your best you bitch, but you will not succeed!". And with that statement Akenos fire ignited up again as well. Hard to see on her face, because she was still smiling as always, but her dick had done the talking by throbbing and pulsing unceasingly, as did her balls. "yes~ that's the Rias that I missed" she thought while pondering on how to proceed.
