The Valkyrie and the Dragon - Chapter One

Rossweisse has been Issei's guardian for years, and a kind of surrogate sister. After Issei's "death" and revival, Ross sees how hung Issei is, and the two explode their pent-up feelings all over each other.

-----------------------------------------------------------------------------------------------------------------------------

Deep in his hall in Valhalla, one of the most prized places of all the gods of the Aesir, the Allfather Odin sat on his throne, deep in thought. A wise and powerful god, at the current moment only thing preoccupied his mind, above all else, something he'd dreaded yet predicted for many years now. It was called Armageddon to some, Frashokereti to others, many different names for all different civilizations throughout time, but it meant the same thing to all. The complete end of all that was, the end of life and perhaps, the possibility of something new. The Ragnarok.

Away from these ruminating deep thoughts on deep, dark acts, it is perhaps odd for one to realize Odin's thoughts concerned individuals as well as the great scale of civilizations and entire pantheons. One tiny home in a tiny part of the world that made up the vast cosmos, in a small city in the island nation of Japan, concerned two people of considerable importance to Odin and his dreams of Ragnarok. Though it would be hard to tell from the noises coming from one of the bedrooms of this house, home to the Hyoudou family-a mother, a father, their son Issei, and the young lady they took in many years ago who was almost like a daughter to them-Rossweisse, a serious girl whose lack of interest in men was only matched by her great clumsiness. But she was no ordinary orphan taken in by this family and was actually many centuries old despite looking no older than twenty.

"Ahhh..mmmh, ahh yesss." Moans filled the bedroom, and indeed the rest of the house, high in pitch and squeaking, squealing intensity. Rossweisse was laying on her bed, masturbating furiously. Her huge tits touched the bed even as she lay flat on her back, clearly visible on either side and from behind her. She was wearing nothing but a thin satin robe that was basically see-through, showing her impossibly stacked and fat bouncing ass, even as Rossweisse herself had her eyes closed. She was rapidly squelching three fingers in and out of her blad, dripping wet pussy, her feet kicking off the bed with her heels stiff, legs ramrod straight and toes pointed in the air. Rossweisse's voice could be heard, mewling to herself as she indulged in a sinful, decadent sexual fantasy.

"Aggggh, Mmmmmmh, Oooh f-fuck it feels so good! Ise, Your cock is so fucking huge~, More baby more, more more! Give everything to me!"

The facts were simple enough. Rossweisse Hyoudou, blessed with the perpetual looks of someone in her early twenties and even able to age or deage when she wanted to. She taught Civics at Kuoh academy, and she often called Mikki and Gorou Hyoudou mama and papa, though they never legally adopted her. As she was squirting right on the floor, lost in the throes of sexual bliss, her free hand groping and smacking at her massive chest with rough, almost punishing slaps, it was clear Rossweisse had worked herself nearly into a frenzy.

This entire improbable sequence of events had started nine years ago when Rossweisse was serving as Odin's bodyguard. At first she'd been excited at the chance to serve him: Odin, the All-Father, Chief of all Norse Gods, Lord of the Hanged, an incredible badass. But it turned out, truth was a lot more disappointing than the legends. Odin was indeed powerful, and incredibly knowledgeable as well, his great wisdom making up for his lost eye, but it was how he chose to use that power and wisdom that let Rossweisse down. The fact was, Odin was little more than a perverted old geezer, who had used Rossweisse as a maid (only later had it occurred to her this was the plan from the start-why would Odin need a bodyguard at all, especially someone like her?) and often mocked Rossweisse for not having a boyfriend, while he used his powers to spy on others in the mortal realm and beyond.

So while running an embarrassing errand for Odin, namely picking up some porno mags, Rossweisse had returned from the mortal realm to find Odin actually looking serious for once, deep in his home in Valhalla. He could only tell her that "Ragnarok had changed." which had sent a shiver through Rossweisse's body-to this day just thinking about Odin's dire proclamation worried her in a strange, tingly way. Somehow, the Red Dragon Emperor of Domination now appeared in all prophecies of Rangarok, which should have been impossible.

A council had been convened, and after days of deliberation, Odin had assigned a personal mission of the utmost importance to Rossweisse. Expecting another boring errand, she had been surprised and confused that Odin had seen her in his vision as well. As such, he gave her the orders to leave Asgard, travel to a place called Kuoh Town in Japan, and intercept the Hyoudou family. This had led to Rossweisse meeting her dear sweet Issei to keep an eye on him as the owner of the Red Dragon, to keep him safe and worst of all, if it seemed he might be contributing to the end of the world, to end him.

From there it had been easy enough for someone as skilled and powerful, if untested, as Rossweisse to manipulate events. She encountered Mr. and Mrs. Hyoudou, appearing as a student of Kuoh Academy who needed their help with a few things. Once they signed what they thought was a simple pledge to help their Issei go to the school one-day, but was actually a document powered by runic magic, their memories had been overwritten. Rossweisse has always been a family friend, and her relatively unchanging age no longer bothered them.

She still remembered when she met Issei, a short, energetic boy who seemed cute as a button, still not yet ten years old. Rossweisse had wondered how a cute boy could ever unleash the end of the world, but it wasn't her job to ask questions. She simply hid out in Midgard, which was easy enough-the only tricky part was getting a job at Kuoh Academy and avoiding the notice of the two Devil families that practically ruled over that place which meant tamping down on her powers at almost all times.

"Yes, Isssei, yes just like that, my big fucking boy, give it to me!" These thoughts passed in a whirlwind through Rossweisse's mind as she finger-fucked herself silly, the bed so soaked that the mattress nearly dripped through to the floor.

It had been unclear when feelings had blossomed between Rossweisse and Issei, looking back on it, she couldn't determine any one moment. But playacting as sister-figure meant she often had to watch Issei when his parents were off on business trips throughout Asia and Eruope. She just knew that one day, glancing at the handsome young man he had turned out to be, she would protect him from anything…even though Rossweisse still twisted and burned at the knowledge that one day she might have to end Issei's life herself. She wondered if Odin, twisted bastard that he was, had planned it that way knowing she would love him and thus keep him from others who might lead him down the wrong path, despite having the secret duty to execute him.

There had been some boys, Matsuda and Motohama who wanted to befriend Issei, but Rossweisse took one look at them and recognized their perverted minds straight away, and quietly steered them away from her pure, sweet Issei. This act, both controlling and caring, struck a nerve with Rossweisse and she began to wonder if this was how Odin thought, manipulating others seemingly without compassion but having a goal in mind that no one else knew about. She hoped not, Rossweisse didn't want to have any similarities with that dirty old fucker. The thoughts did still resound in her head, even now as she worked herself to another frenzied climax in bed.

Yes, I was supposed to be his watchful guardian and executioner rolled into one…yet I failed.

Earlier that day, the family had shared a nice cozy breakfast together, though Rossweisse had long ago learned that these happy Hyodou meals always had a price attached. Here, it was that they were going on a business trip, which was both important news and so commonplace as to be ignored. Rossweisse was deep in thought about Ragnarok, while Issei ate his food without looking, choosing instead to stare at Rossweisse.

"Careful Issei, if you look at Ross like that in public, people might think you're together." Gorou teased with a sly smirk.

"That wouldn't be so bad." Issei replied, but his words were so fast and mumbled that Ross didn't hear him and his parents barely understood him.

"What's that dear?" Miki asked, but she was scrolling through her smartphone making last-minute preparations for their trip.

"Nothing."

When the meal was finished, the family each went their separate ways. Miki and Gorou went through their belongings one last time,making sure they were packed and ready, while Rossweisse made a list of all the boring household tasks that were her responsibility now. Dealing with Odin was annoying enough, but dealing with credit card companies who thought the Hyoudous spending habits were odd was a punishment Asgard could never conceive of.

Issei for his part had run off to take a shower, leaving Rossweisse with the two elder Hyodous.

"He has been acting strange lately," Miki said. "Probably something to do with that girl, Yuuma something. Maybe they've been having trouble and that's why he's so gloomy."

Gorou nodded, even as he messaged a taxi company to pick them both up for their trip to the airport. "Well, I just hope they can work it out, because otherwise we'll probably never have grandkids…well, except for any kids you might have, Ross-chan. I suppose they could call us Gramps and Gramma."

Rossweisse was suddenly stirred out of her funk, her eyes wide. "Neh? I…I don't think I'd be having any children that would be your grandkids. I mean, after all Issei has a girlfriend anyway so the chances of me getting pregnant and carrying a Hyoudou child are slim to none at best…"

She muttered under her breath, with an almost visible dark cloud forming around her head as she vented negative thoughts in a flurry. Gorou and Miki shared worried glances and decided this was the time to make a swift exit. Ross barely noticed them leave.

"Damn that school, and all the work I had to do to become a teacher, this is all the fault of that damn Academy. I was supposed to keep an eye on Issei, steer him clear of girls and now someone is sniffing around the Red Dragon. How could things get any worse?!" Tears streamed down her face before she wiped them hurriedly, knowing she had to put on a brave front.

Gorou and Miki closed the door, remarking how odd it was that Rossweisse was so worked up at the idea of Issei having a girlfriend. Probably just jealous she didn't have a boyfriend, they assumed.

Rossweisse headed towards the bathroom, still muttering and mumbling to herself, worried that some hot girls might lead her Issei astray. Yuuma Amano wasn't a Devil as far as Rossweisse knew, but threats to Issei, and thus all of creation, could come from anymore. Issei was an attractive boy and very stupid when girls were around, which was a dangerous combination perfect for others to wrap around their fingers and manipulate to their heart's content. Rossweisse's feet, wrapped in cute thigh-high white socks, pounded the floor as she neared the bathroom, one of her fists balled up in an almost cute expression of anger.

She must have forgotten Issei was taking a shower, or what happened next wouldn't have occurred, but maybe there was more to it than that. With her conscious mind so preoccupied with thoughts Rossweisse's long silver hair was bouncing around her like an agitated lion's mane, perhaps some quieter part of her brain decided to take action.

Inside the bathroom, Issei wasn't quite showering, though he was nude in the tub with the water running. His concerns were elsewhere, and hardly concerned with cleaning.

"Mmmh, oooh, mmmh~" Issei bit his lower lip cutely, his face screwed up in an expression of concentration and pleasure. His cock stuck out like some sort of massive, oversized club, and even with both hands Issei couldn't get his fingers to touch around the throbbing, veiny shaft. The massive bellend was level with Issei's eyes, sticking up like some kind of monstrous spear as Issei worked himself faster and faster.

Ahhh…I don't care if the President scolds me for daydreaming, I don't care if I have to face more Fallen Angels with huge tits and lasers, I don't care about dangerous crows that turn out to be something else, I'm just so grateful for tihs big, huge cock. I just wish I could use it on the President and Akeno's fat, titantic tits, even the two of them wouldn't be able to cover it all the way!

Rossweisse was, indeed, too late to prevent Issei's life from changing. His first girlfriend had turned out to be a Fallen Angel who wanted him dead, and from there, Issei's life had taken several bizarre turns. Now his cock was ten times as big as it had been, something Rias had mentioned was due to his Devil nature, but admitting even that couldn't account for such a large change. Unknown to any of them, Issei's Red Dragon powers interacted with Issei's long-hidden perverted desires and enhanced his dick size permanently.

So focused on pleasuring his new, massive, one hundred centimeter cock (that was Issei called it, liking the round number, but it was actually slightly larger than even that insane size), Issei didn't notice the bathroom door opened. Rossweisse was standing in the doorway, staring at Issei and his huge bitch breaker of a cock, her jaw wide open like she was trying to catch flies, her aquamarine eyes shrunk to narrow pinpricks of color, nearly all-whites in her stunned state.

Oblivious that he was being watched, Issei continued jerking his cock, his lewd inner monologue becoming audible as his climax grew closer, words spilling from his lips in a tight, strained voice.

"Oh fuck, just imagine what I could do with those huge volleyball breasts. They're as huge as my Nee-chan, Ross'.

Hearing her name, especially mentioned in the same breath as the phrase huge volleyball breasts made Rossweisse's face suddenly resemble a tomato, red and swollen. She did glance down though at the little jersey she was wearing and admitted Issei was right-she'd bought a men's size that was supposed to be way too large for her, but her enormous tits meant the whole thing was tented out. She wasn't up on all her human sports, but volleyballs honestly seemed a little small in comparison.

"I…Ise!" Ross said, sputtering and unable to think of anything meaningful to say.

Only then did Issei notice, making him turn to face the door, still jerking that cock. Getting a look at it was like staring down the barrel of a cannon, and Rossweisse felt a spark run up and down her spine as she finally got a good look at that massive, pale cock, throbbing with veins that were thicker than two of her fingers put together. Her knees shook and her heart skipped a bit…was this what they meant by "love at first sight?"

"Ah, Nee-chan!" Issei couldn't believe his entire cock was on display, his fat balls churning up as he kept jerking off, full of enough sperm to overflow a kid's wading pool…and then some.

Seeing that cock made Ross think of Jormungandr, the world serpent, impossible large…just like this dick. Drool trickled from one side of Rossweisse's mouth, smelling that cock even from where she was standing, as the musk filled the room like overwhelming perfume and Issei's pre-come stank to high heaven. Normally she was smart and calculated, but right now she felt like she'd lost ten IQ points, the only thought she could hold being that if Issei took just a few steps to her, just three small ones, no more, that cock would be pressing right up against her body. His cock would lead the way and Rossweisse wouldn't even be able to touch the base.

Issei held his hands in front of his shaft, in a pointless attempt to hide it. All he did was highlight how large it was as both of his palms, pointed down and side by side, still left some of his huge, throbbing purple prick helmet visible from either side.

"Well, this is…this is…" Issei couldn't believe he didn't lock the door, tripping over his words. But just maybe, a slow thought trickled down the back of his spine that maybe that was a good thing.

"Ooowaah-KYAAAHHH!" Rossweisse could take no more, and ran from the bathroom in a hurry.

"Nee-chan!" Issei called after her, but it was too late and the bathroom door rattled in its frame as she slammed it shut. He wanted to go after her…but he couldn't really move like this, not when he had been so close.

By the time Issei had finished jerking himself off and washing himself off, Rossweisse was locked in her room, not speaking. Eventually he closed himself away, locking the door and collapsing on the bed in shame and embarrassment. Issei threw a pillow over his face, lost in his own thoughts and thus not able to hear Rossweisse's moans and groans

I can't believe that happened, oh my god I'm so humiliated I could just die!

All of this had happened hours ago, and Rossweisse was now, currently, still in her bedroom masturbating. Her teeth clenched as she came again, having reached her third orgasm while thinking about nothing than that massive dick she'd looked at. It had been like the first time she'd seen Valhalla, but without any letdowns, and the fact that the most massive, huge, ungodly cock she'd ever seen belonged to her dear sweet Issei, it was too much to handle.

"Hah, hann, hannnh" She panted, pussy juices having shot so far from her spasming cunt that they'd actually hit the far wall across from her bed.

"Alright! I can't fucking take it anymore!" Rossweisse said, a bit of fire in her eyes. It had been a long time since the bodyguard and errand girl had gotten so worked up, but she was still a Valkyrie at heart, which meant she was a powerful warrior who wasn't going to hide in her bedroom like a lovesick teen.

Rossweisse gathered her robe, taking a look at herself in the mirror absurdly-since when did she check what she looked like before talking to Issei? But something had changed since she'd seen what her "little brother" was packing between his legs. She adjusted the pink ribbons in her hair, her makeup looking nice and polished but not too obvious-she had this.

Whatever this is…who would have thought my dear Issei…well, I have to get to the bottom of this, one way or the other!

Rossweisse knocked on Issei's door once she left her room, but got no response. She tried to turn the handle, but it was locked. Clucking her tongue, Rossweisse concentrated, calling upon a little of her magic to unlock it from the inside-it was very easy to do, but it just reminded her of how long it had been since she'd actually relied on her magic and had simply been observing Issei through normal means for so long. She tiptoed inside, walking towards Issei's bedside.

It stinks in here, but I know Issei cleans his room every day, I've seen him. But the stench of cum is so powerful…he must jerk himself off every day, just like I do. Does he think of me?

The thought was almost too hopeful for Rossweisse to bear. As she drew neared, watching Issei sleep, he seemed completely different from the dirty, perverted, hung like an elephant young man she'd seen earlier. So innocent…he was even still wearing those little blue briefs of his…well not wearing, Rossweisse noticed, they were flung to one side of the room.

Of course he's not wearing them-with such a monster swinging between his legs, those things would only be in the way.

Rossweisse reached the sheets covering Issei's lower body, and for almost a moment, she hesitated. Things had changed so fast between the two of them that she didn't know where she stood…but she couldn't help herself. In a flash she tossed the sheets away, flinging them entirely off the bed.

"Holy fucking shit Issei~" Rossweisse purred low in her throat, clearly smitten.

Issei's cock was laying on his legs, rather than in-between as it was simply too large and thick for the space between his skinny legs. Instead, it lay coiled like some obscene missile or other weapon of war, yet it was completely flaccid! Yet already it was the single biggest cock Rossweisse had ever seen, and she stared at the mammoth dick with twinkling sparkles in her eyes, clearly considering it the grandest prize in the mortal realm or anywhere else. This, then, was obviously her reward for years of service as a good Valkyrie.

Rossweisse simply leaned closer, blowing hot air towards that colossal, yet soft cock. Like magic, it immediately responded, growing harder, and thicker, and longer before her very eyes, like some monstrous third leg.

"Oh Ise~" She cooed, clearly impressed and unwilling, or unable, to hold herself back any longer. Rossweisse reached out, leaning forward with both of her hands outstretched as she began to slowly wrap her soft palms and long, agile fingers around that cock. Rossweisse's eyes grew wide as the massive cock began to grow slightly harder, stiffer on the inside yet still flexible, not fully hard. Her hands couldn't wrap all the way around that dick, but that wasn't going to stop her from doing her all.

Rossweisse climbed onto the bed, careful not to make too much noise as she started to lick at that cock, working her way up from the base along the veiny underside. The veins ran hot against her face as that cock leaned over her, unable to support its own weight. Pre-come dripped down onto Rossweisse's back, soaking through her robe but not deterring her in the slightest. When she reached the massive, throbbing, flared cock-tip, she began to kiss it like a long-lost lover, though in truth, Ross had never actually kissed anyone before. The skin of Issei's cocktip was so hot it nearly scalded her, and the entire thing was so large she had to crane her mouth open like a snake trying to swallow a plump rat. Drool soon ran from the corners of her lips as she took her time, slowly working the first few inches in and out of her mouth.

Issei's cock glistened with Ross' bubbly, cloudy saliva, bobbing under its own weight as she tried to hold it steady which wasn't easy, even with her deceptively strong, slender arms. Holding it firmly in place, Rossweisse began to bob her head forward and back in a slowly accelerating rhythm, swallowing the entire purplish tip and then popping her lips off with a loud, clear noise, her cheeks beginning to hollow out as spots of color appeared on her porcelain skin. Rossweisse took it down her throat a little bit more each time, beginning to take more than six inches with each downward swoop of her mouth. Then eight inches until Rossweisse's eyes crossed as she looked down to the base of Issei's cock, realizing she had only taken in about one fourth of this still growing monster.

Oh god, my jaw is definitely gonna be dislocated if I go much farther…but I don't give a flying fuck about that!

One of the reasons Odin had picked Rossweisse for this mission (aside wanting to mock her for not having a boyfriend and assigning her to a human family) was her sense of determination. She may not have understood or liked her orders, but she would carry them out, and at this moment she'd given herself the personal mission of sucking this fat donkey dick.

"Mmmm~" She moaned at the taste of it, filling her mouth and nostrils with the strong, tangy musk of Issei's manhood. This is fucking delicious!

Slowly, reluctantly, Rossweisse pulled back from Issei's cock, finding it to be the most difficult thing she'd had to do in a very long time. The second it left her lips, with strands of saliva connecting her lips to the fat prick helmet, Rossweisse dived back in, shoving her face against tjat shaft and licking up and down the entire massive thing. It felt like she was licking for a veritable kilometer along that delicious fuck stick, dragging her wide, long tongue against it while making distinctly un-ladylike moans grunts. She sounded like an obese child devouring their favorite sugary snack, happily leaking drool and spittle all over Issei's cock, working it in with both hands to get his cock nice and hard, wet and sloppy.

Once she felt the cock was well taken care of, Rossweisse climbed more fully onto the bed, lowering her head between Issei's skinny thighs and beginning to worship his fat, humongous balls. They were hairless like the rest of his body, and that just reminded Ross of how young he was, and a shudder went through her body as she imagined how much bigger he might get as he grew older The huge, wrinkled sack of dark skin surrounding the two enormous testicles seemed as large as Rossweisse's own head, but she wasn't gonna let that stop her. She sprayed hot waves of bubbly spit over each swarthy nut in turn, before finally craning her mouth open wider than before, hearing a distinct click from her jaw as began to suck on the massive testicle. Her cheeks were hollowed out as her tongue began to swipe up all the sweat and dirt on the huge sperm tank, her mouth stretched impossible wide in lewd fellatio face that would have seriously injured a normal woman.

Thank the Allfather I'm as strong as I am…of course the pervert probably likes that Valkyries can swallow such massive balls.

Rossweisse sucked the sweat from Issei's testicle like a washer woman wringing dry a washcloth before she slowly let it fall out of her mouth, feeling her jaw ache. Rather than rest up and hope her mouth felt normal again, Rossweisse simply switched to the other testicle, playing with both as she lavished hot, sultry licks of her tongue and deep, open-mouthed kisses all over Issei's balls. With her tongue pressing at the thin seam of his nuts, her shook her head vigorously from side to side, actually blowing air out of her mouth like some teenage boy motorboating a pair of fat tits…which honestly, wasn't far off as Ross had seen girls with smaller chests than Issei's elephantine balls.

Rossweisse gripped the hard cock by the base now, lifting it up and marveling at how heavy it was, the way it swung through the air with clear noises like a club.

Smack smack smack!

Rossweisse giggled like a schoolgirl as she smacked her face with the huge cock, eyes wide as she stared at it. A beast like this could really do some damage…she smacked herself again, playing with it and stroking it with fascination in her eyes, never having seen something so magnificent before. Her cheeks were soon red from the impact, with little imprints of Issei's massive bellend on them before she smacked it on her lips, kissing it each time with loud wet lip-smacking sounds. Holding it firm again, Rosswessie began to bob her head up and down, trying to take more this time, forcing her head down with all the effort she could muster.

"Glaag, glcch, glaacck!"

Ten inches of fat bitch breaking-cock was stretching her jaw and bulging out her grasping, tight wet throat, but try as she might, Rossweisse couldn't swallow any more. Drool fountained down her lips as she jerked the rest of that cock off, which was far, far more than she had in her throat. Rossweisse concentrated once more, calling upon Runic magic that she hadn't used in some time. Bright crystal-blue runes sparkled on her shoulders, before a pair of hands made out of star-like energy appeared, grabbing Rossweisse by the back of the skull.

"GLLLLLCHHHH!"

Despite her own body resisting, and sounding like she was going to vomit all over that godly cock, Rossweisse's face was forced lower, inch by inch. Her porcelain skin turned an ugly shade of red as her airway was constricted, and precome began to trickle down her throat, burning from the inside with thoughts of lust, even as tears and snot began to streak down her face as well. So much for checking her makeup, she must have looked like a dirty cocksucking whore right now, and yet that seemed like the most natural, right thing in the world to Ross in this moment, utterly in lust with Issei's cock and showing it more affection than she'd ever shown a man in her life.

The sounds of choking, slurping, and dripping saliva filled the room, as Rossweisse swallowed half of that cock up and down her throat furiously. Between her own efforts and the astral hands she'd conjured up, Rossweisse bottomed out, her throat stretched all the way with cock but she still wanted even more. This time, she knew what she had to do, calling upon Norse Magic that she hadn't used since before she was Odin's bodyguard. The runes shone over her entire body, and her thin robe began to tear as her body grew.

Schr-iiiip!

Soon, Rossweise had expanded in size, her body having grown slightly more muscular as well as she stood nearly nine feet tall. This was Valkyrie combat magic, something reserved for the battlefield, and yet only now had Ross found an opponent that she truly needed help with, something that overwhelmed her normal slutty, energetic but still inexperienced body. Now she truly resembled the glorious warrior women Valkyrie were supposed to be, with her muscular arms, washboard abs, and long, sculpted legs.

And it's all for this cock…Issei, what are you doing to me? And without even trying…I just can't resist.

"Glaccgh, glllck, schlllorp!"

Rossweisse made lewd nasty cocksucking noises as she went back to giving Issei the best blowjob she could, swallowing it deeper and deeper with each bob of her head. She was using her mouth like some kind of milk extractor, wanting to suck the jizz right out of Issei's balls, slurping at that impossibly huge dick like her life depended on it. Her hands furiously worked his balls, kneading and stroking them, trying to will him to produce more jizz just with her sluttiness.

Ross' hands moved up from ssei's balls, beginning to shred the thin t-shirt he was sleeping in, revealing his pale, skinny torso. Still, he had some muscle there, and Rossweisse started to stroke his body with her now larger yet still dainty hands, caressing his abs and chest. Her face turned red from how long she'd been sucking that cock, and precum leaked from both of her nostrils in a nasty, crude display of submission and dick-sucking hunger.

I've been sucking his cock for so long…and he still hasn't come! It feels like my jaw is gonna be permanently broken if I don't stop soon, but I can't stop until Issei gives me that big fat load! I can just use magic to fix my mouth later, who cares if I can't talk normally for a week or two! Issei is worth it~

Finally, almost an hour after she'd started sucking that cock, Issei's dick began to twitch inside Rossweisse's mouth. She knew she had to go for broke now, show much she was devoted to this cock, even if Issei was asleep, no matter what. Concentrating and using all her magical strength in her enlarged body, Rossweisse opened her jaw wider than ever, cupping Issei's balls. First one pushed into her mouth as she speed spit all over the other one-it should have been impossible, and would have been for a normal woman, but eventually with a tremendous sense of accomplishment, Rossweisse managed to pop both of those fat sperm tanks into her mouth. She was sucking the sweat right out of them, her face horribly distended in a lewd whorish expression as ehs worked her throat, making exaggerated swallowing sounds.

Spllrt! Spllrt! Splllrccch!

Finally Issei was pushed over the edge, and a massive flood of sperm was released inside Ross' body. Even with her new huge size, her stomach began to expand soon as well, each fat rope of jizz piling up inside her like wet cement, tenting out her abs and deforming her strong athletic body, remade to look like a pregnant sow nine months along. Ross just concentrated, using her Runes to absorb the cum inside her stomach, feeling the masculine energy of Issei's divine sperm fill up her entire body. Her stomach slowly returned to its normal size, even as Ross panted, nearly coming herself stupid from swallowing that fat load, laying flat on her stomach to better accommodate that dick.

Issei moaned, his eyes blinking as he slowly roused himself from sleep, looking down at Rossweise as she slowly let his cock fall out of her mouth. A last thick jet of his off-white sperm shot out and Rossweisse opened her mouth like she was catching a treat, happily gulping the virile goo down. She winked at him, eyes sparkling.

"My my Ise~ With this enormous load and this huuuge fucking cock…you sure know how to make a girl feel special."

Issei's eyes nearly bulged out of his head he was so surprised, but his cock was already getting hard again with a mind of it's own as the teenager tried to wrap his head around the situation that was at once both obvious and completely unexpected.

"Nee-chan!? Wha…when, how are you….oh god~" Issei moaned, laying back against the bedframe as Rossweise began sucking his cock again, her lips so soft and her tongue working him in just the right ways.

She popped her mouth off, smiling at him wickedly. "Do you want me to explain? Orrr….do you want me to keep going until we're both satisfied.

Issei couldn't even form words this time, just stammering and stumbling out meaningless syllables. Eventually, Ross just raised a finger and waved it at him like the teacher she was.

"I'll take that as a 'No, please keep sucking my huge cock, Nee-chan.'" She giggled, feet kicking in the air as they hung off the bed, which was far too small for her new form.

"Ok then Issei, because you asked so nicely…schllorp, schhhlrp, glitch!"

Rossweisse went right back to servicing that monster cock, making Issei squirm on the bed. He'd never experienced so much pleasure in all his life, this was so much better than when he jerked it in the tub, or in bed, or in the bathrooms at school.

Issei's moans were louder and more aggressive than ever, yet somehow Rossweisse was making even more noise. Between her happy, cock-greedy moans and the way she drooled all over his cock, she was much larger with happy mmphs and wet nasty slurping sounds filling the small bedroom.

Issei leaned back further, his legs trapped beneath Ross' muscular form as he struggled to take this all in-his "big sister" was sucking his cock like she was trying to fit a golf ball through a hose, and she'd almost doubled in size to nearly three meters tall, handling his freakishly large cock like an old pro.

"Oh my god, Rossweisse! Where did you learn how to do that? Have you been…seeing some other guy?!" Issei asked, more than a little nervous, especially since he was the one who had gone on a date recently.

Rossweisse slowly pulled her mouth up off his cock, her hair swishing about her body in gorgeous waves. Her cheeks flushed, somehow more embarrassed to be asked that question than she was to get caught with Issei's cock stuffed down her tight throat.

"Ah, don't be an idiot! O-of course not! This is…" A trickle of sweat ran down Rossweisse's forehead, growing anxious.

"This is the furthest I've ever been with a guy…a lot of my knowledge actually comes from porno mags." She said, embarrassed but at least glad they were good for something.

"So I've been practicing…see?" Ross practically slammed her head back down on that cock, deepthroating it again with a lot of difficulty, but still easier than the first time. Her mouth gurgled as she let out drool all over Issei's hairless balls, coughing and retching on that cock as she swallowed every bit of that Hundred and One Centimeter cock.

"Wow, my prim and proper "big sis" Rossweisse owns a stack of porn magazines…you must be as perverted as me!" Issei said, overjoyed at this news.

Rossweisse cocked one eyebrow at him, a little stung by his words. She wasn't a pervert…not really, she just couldn't help that she loved this dick! So she swung her body around, her throat making nasty retching sounds as she actually spun her mouth on Issei's dick, before she positioned her huge fat ass right above his head. Issei had just enough time to draw air in his legs before Ross tensed her thick thighs and dropped that ass on his face, hiding his head from view.

Rossweisse stopped sucking his dick just for a moment, speaking to Issei and wondering if he could actually hear.

"If you can talk shit, then you can put your mouth to work, now get moving!"

In this sixty-nine position, new for both of them, the pair were soon writhing on the bed, a happy, spasming mess of nude, tangled sweaty limbs. Issei groped her fat ass as Ross happily choked on that cock, his tongue diving in and out of her pussy and tracing her labia. An electric shock seemed to run through her sensitive clit as Issei licked her with enthusiasm and energy that made up for his lack of experience, with Rossweisse never having felt anything so good, it felt like her body was suddenly on fire.

After ten minutes or so, with Issei's spikey hair rubbing against her thighs and his fingers groping every inch of her firm, gravity definyg bubble butt, Rossweisse coudl feel an orgasm growing, one larger than any of the three she'd finger-fucked herself to earlier today. Issei, her cute little Ise, her sweet boy, was gonna make her pussy fucking gush all over his darling face. For a moment, she lay limp against him, lost in the pleasure, but a competitive streak ran deep in Ross-she wasn't gonna let Issei make her come first in this position.

The runes on her body burned brighter than before, making her robe vanish completely and showing every inch of her gorgeous stacked frame. With her humongous breasts now totally free, she wrapped them around Issei's cock, working whatever she wasn't sucking at any given moment with those perfect Valkyrie jugs. Issei let out muffled moans from under her ass, grabbing onto those perfect cheeks for dear life, his fingers causing her thick booty to puff out around his grasp.

In this way, Ross got the upper hand again, and in another five minutes or so, Issei's moans reached a fervent pitch.

"Mmmph, mmph, mmmpbbblr!" He tried to warn her, but he couldn't speak and could only lick and slurp at her pussy lips faster. But Rossweisse got the message all the same.

Acting fast, she used both hands to gold the base of Issei's cock, holding him so tight she managed to stall his orgasm. She shook in pleasure as she looked down at that huge cock and realized even now in her nien foot tall frame, she couldn't fully wrap her hands around his dick, it was close, but he was still just too big-what a hunk her "little bro" was. Rossweisse lifted her ass up, nearly throwing Issei from the bed as her legs swung around his much smaller frame.

"No baby, not yet! I don't want it in my mouth again, I got plenty earlier, you stud." She displayed her sheer athleticism, lifting one leg straight up over her head, pointed at the ceiling. She turned her body to face Issei's, his slender skinny form looking very small indeed below her nine foot frame, except for his massive cock which she was stroking slowly but firmly, not wanting him to cum but wanting to keep him right on the edge.

"I want it here!" She swung her hips, positioning her dripping wet pussy right over Issei's mammoth dick. Issei moved with her, his cock sliding past her pussy lips and reaching up to nearly spread between her huge tits, which, given her new height, was truly amazing.

"Are you sure about this Nee-chan? I've been waiting for this moment for so long, I'm not sure you know just how much I really love you. Are you really ok with doing this with someone like me…even with my huge dick?" Issei asked, blushing a bit as he considered his enormous cock and the effect it must have had on Ross-no one else had ever seen his dick, so he wasn't quite sure how women would react, but Rossweisse's reaction was a promising start.

She paused for a moment, before she leaned in and the two were suddenly passionately, firmly kissing. Issei's lips worked against Ross' tongue as she slowly pushed it into his mouth, before he pushed back, the two of them pulling each other forward and back, slurping and swapping spit. She caressed his face and moaned, briefly breaking the kiss to speak, her heart skipping a beat.

"Oh you fool, Issei! I fucking love you like I've never loved anyone! Your elephant dick is just a bonus…an incredible, gargantuan bonus. But I don't want you to consider anything else. Just fuck your "big sisters" tight little snatch until morning! Trust me I'm a big girl now I can take it."

With a swift motion of his hips, Issei's cock met the firm resistance of Rossweisse's virgin pussy, and giantess or not, she was still incredibly tight. Yet by pushing up as she squatted down, her labia resisted for one moment and then suddenly his cock punched past them, tunneling up inside her like some massive drill. Already on the edge from his oral efforts, Rossweisse came as that cock slammed up inside her twat, her pussy gushing as she kept her leg high in the air, resting it on Issei's body and letting their sweaty forms rock and grind against each other as she squirted everywhere, coating the bed and the two of them with her pussy juices.

"Ohhh…my fucking god!! ISE!!! It's too fucking massive!!"

Isseii was soon rearranging Ross' insides, making room for his cock as her tiny vaginal canal stretched farther than she ever thought possible.

"Aaagggh, it's so fucking tight!" Issei grunted, feeling like he was trying to work a baseball bat through the eye of a needle. Rossweisse just kept coming like crazy.

He didn't just break my hymen, any man could do that…he fucking obliterated it, like it was nothing! My strong valkyrie body couldn't resist him, and now he just keeps plowing it deeper and deeper inside me! My organs are being rearranged for this nasty fucking bitch breaker! What happened to my sweet boy…I must have awakened something inside him!

Indeed, Issei was rampaging in that tight cunt, letting out years of sexual frustration with his newly enhanced, perfect, pussy-crushing dragon cock. Rossweisse came again and again, screaming her head off.

"Fuck, fuck fuck! Ise! Slow down a little!"

It was like she hadn't said anything at all, as he didn't react. If anything, his thrusts grew faster and she couldn't believe how strong his body felt, his small hips crashing against hers and that fat cock driving up inside her stomach practically, knocking the very air from her lungs. Issei was finally living out all his nasty lewd fantasies, with his big sister figure's tight pussy wrapped so tight around his cock she was like a living condom, and he wasn't about to stop now. Rossweisse could only beg him, tears of joy streaming down her face as orgasms were wrenched out of her body, feeling like she had been struck by lightning.

"PLEASE! MERCYYY-AGHHH!!"

"Fuck no!" Issei growled like an animal-like a dragon, she realized- and went even faster. He was grabbing her fat tits now as he pushed her back on the bed, her knees nearly touching her face. Once he got a hold of those breasts, those perfect, marshmallow heaven jugs that he'd been jerking his cock to for years, he knew he could never let them go. Issei motorboated Ross' fat jugs, making her moan at the sensation, feeling like even though she was the stronger one, Issei was just using her for his sexual pleaure. He drooled on her tits like a madman, sucking on her nipples and switching back and forth, worrying them with his teeth, making Rossweisse's eyes roll back in her head. The left tit, the right, both at the same time, Issei was going to devour them, knowing he would never stop playing with these breasts, one way another, for the rest of his life.

"Oh fuck baby, don't you fucking stop keep going, keep going!"

AFter thirty minutes of raw, almost angry fucking, Issei was going to come once again, his face flushed with the effort of pounding his titanic titted "big sister"

"Oh fuck Nee-chan! I'm gonna, I'm going to…fucking explode!"

It was as if flood gates had opened, as Issei's orgasm now was more than double his previous load. With ansty wet splurting sounds and the smell of hyper virile dragon jizz filling the room, Rossweisee's stomach flooded as her womb was full to the brim. She was trying to absorb it as before, but there was simply too much. In a flash, the runic energy around Rossweisse began to shatter…meaning she was going to return to her normal size with that massive cock lodged balls deep inside her. She could feel it in her neck now, and trying to speak was a massive effort.

"Ah gahd…Issei~ Well, I guess we are done for today….right Ise?!"

Issei lifted Rossweise, as her normal frame was a lot lighter, pushing her onto her belly on the bed. Then he grabbed her legs and arms, twisting her body into a prone full nelson position as he lined his cock up and-

WHAM!

-he just fucking slammed right back into that dripping pussy, sending his own jizz and Rossweisse's pussy juices spraying everywhere. The bulge in her body was nearly reaching her neck, and Issei could feel her tits stretched out around his cock from the inside, making him groan like an animal.

"ISE!!!! Oh fuck, I'm not big anymore if you keep plowing me like this, I'll become pregnant for sure!" She may have already been pregnant, but her runic magic should have protected her. Should being the key word, as she'd now shrunk back to normal so who knew what Issei's cock could do to her like this.

"I'll be forced to give birth to your elephant-cock babies forever!!"

Issei grunted in her ear, his arms wrapped around Rossweisse's delicate swanlike neck in a firm chokehold. She was still stronger than him, but he was gonna get the most out of how dick drunk and in a daze she was, as his balls still had lots of sperm to drain.

"That's the idea! From now on, you're mine forever! So let's have lots and lots of babies together Rossweisse!" He plowed her hard, not letting her go or rest. Instead he went faster, the perfect vision of a sister that he had once had for her gone. Now, as they fucked for hours, Issei just considered her to be his first eternal cocksleeve.

He fucked her doggystyle, smacking her fat ass and watching how it rippled in waves like a tsunami. He made her lay prone on the bed and bite a pillow as he fucked her pussy. Issei lay underneath her as Rossweisse rode his cock, her tits bouncing in a slutty cowgirl position as she moaned, fingering her own greedy cunt and making herself squirt over and over again, feeling like she was losing sanity with each climax. It was on that monster cock, riding it while Issei bit and kissed and sucked at her tits, leaving hickies and bruises all over them, that Rossweisse, the pure beautiful teacher of Kuoh Academy, finally broke once and for all.

She didn't care about the world, or Ragnarok, she only cared about milking that cock. Which she did, again and again and again, taking another six monster loads in her pussy, with no amount of magic able to hold them back, leaving her a leaking, gaping mess.

Eventually she lay on her back underneath Issei, who was resting for a moment as she began to tell him the truth of her mission

"So all our memories together…were based on a lie?"

She shook her head, face still flushed and clenching her legs around his waist, that gargantuan cock still buried inside her.

"No, it was all true! That's why our memories will be treasured forever..I just needed to watch you, that's all."

Issei's ego stung a little, but once he decided to take it out on Rossweisse's pussy all over again, he felt better. The bed groaned beneath them, sure to break at any moment just as Rossweisse had broken for Issei.

Nearly ten hours had passed since Issei first felt the unbelivabel tight wet heat of Rossweisse's pussy on his cock, and they were still having wild sex, with no one to interrupt them now. Rossweisse was riding him in a cowgirl position again, her hair and skin covered in jizz and just an absolute mess. Her pussy was gaping, perhaps forever, red and raw and sore and leaking juices as she had nearly one long constant orgasm, each explosive climax building into the next. She couldn't care less about any of that though, as having that dick inside her pussy was the only thought in her mind. Hearts shone in her bright blue eyes as Rossweisse let out girlish, high-pitched moans. Her face was in contrast to the beautiful, birdlike noises she was making, as it was a nasty, lewd, dick drunk ahegao expression, her eyes crossed, her tongue sticking out and her sense of pride or decency gone, quite literally fucked out of her head.

Issei was trying to talk to her, explain himself, but it came out garbled between him sucking on those titties and letting out animalistic grunts and pants from her skillfully (if a little exhausted) riding his cock still.

"And…that's how I became a Devil, nee-chan!" Issei was overjoyed, never knowing life as a Devil could be so good-if he had known all he had to do to get a cock like this and the girl of his dreams was to die for a little bit, he would have jumped at the chance ages ago.

Rossweisse panted, her face a dark red as she moaned. "Haahhh, I'm coming again! Motherfuck it feels like my brain is being fried each time…I don't know how much more I can take…but oh, Issei…I'm so sorry I couldn't protect you baby."

"Oh don't worry, you did your best but you were so busy being a teacher, nee-chan! But I have met more people, and learned more about the world…and now as a Devil I have a cock that can make you feel this good!"

Wham! Wham! Wham!

He went even faster, motorboating her titties and spanking her ass to encourage her to take the cock like his happy little bimbo girlfriend.

Rossweisse moaned her last shreds of sanity trying to focus on the important information Issei was telling her and not just his cock…it was the hardest thing she'd ever done.

"But still….ooh baby, right there, right there, that's your sister's sweet spot baby, hmm, you're gonna make me come! Still…fallen angels could be dangerous."

She didn't even know if Issei could hear her over the sounds of him motorboating her tits, but slowly he stopped, looking up at her with concern on his face. It didn't' stop him from fondling her tits and ass though, wanting to grope and grab and squeeze and feel every inch of her wonderful body.

"That's true…I suppose they need to be taken care of, and there are some things I need to do for Argento. How strong are you, nee-chan?" He rested his head on her beasts, looking up at her face.

Rossweisse's eyes flashed-who was this Argento? A girl? Better not, or she would…

"Ooh, that's it, I'm coming!!" She cried out, losing her train of thought as she squirted all over Issei, her body feeling more tired and worn out with each orgasm and yet they were still stronger than ever, blasting her body with pleasure. Rossweisse realized he'd asked her a question and struggled to answer.

"Once…I was Odin's bodyguard."

Issei smiled wickedly, still rubbing his face between her tits, in the massive valley of her cleavage. "Well, I think Kuoh has a 'Crow' infestation, would you mind doing something for me?"

Issei had found the perfect way to ask for anything, as Ross was going to come again. She hugged his head close to her body, caressing him with those tits he loved so much.

"ANYTHING FOR YOU BABY! AHHHGHGGH!"

Excellent, Issei thought. He had a plan, but that could wait. With a grunt, he began to come inside her again, splattering her pussy with more sperm than she could hope to hold. She was starting to think absorbing it earlier with magic had been a bad time…could someone become addicted to jizz, like a drug? It certainly felt that way to her-each time she got it, she craved it more and more. If she ever had to be apart from it…no that was too dreadful to even think of.

Issei was still hard, and with nothing else for them to do until the following week of school started on Monday, it seemed he might fuck for the whole rest of the day, and into the morning. That was just what Rossweisse was hoping for, as she pledged her body and soul to Issei in that moment, forgetting all about Odin, or Ragnarok…the world could take care of itself, she thought. Just so long as she could have her cunt get wrecked by this cock far worse than any Hammer of the Gods could ever be used on the world. She screamed out over and over, loud enough to be heard for blocks around.

"Kuu-waahhh! I love you Issei!"

It was the best day yet of Issei's young llfe…and things could only go up from here.

To Be Continued…
