The Valkyrie and the Dragon - Chapter Four

It had been an eventful, and not entirely positive, few weeks for Issei. First, Asia Argento had been adopted by the Hyoudous at the command of Rias Gremory, while Issei's parents had quickly accepted before going off on yet another business trip. Issei thought that someone was manipulating them, maybe even messing with their minds using magic, but he couldn't be sure who it was and honestly…he didn't mind that much. Not having his parents around made it easier to focus on his growing harem, which had started with his 'Big Sister' Ross, his 'Housecat' Kuroka, and now the Fallen Angels. It was a pretty large group, especially with three of them living in his house, well two and a half. Nothing had happened between Issei and Asia just yet, but it seemed inevitable, which Kuroka and Rossweisse were obviously jealous of.

That had been the state of affairs until recently, following an encounter with Rias in the middle of the night. She'd come to Issei's bedroom to plead with him to take her virginity, but they'd been interrupted by Grayfia Lucifuge, Rias' sister in law. Grayfia had chased Rias away, and then offered herself to Issei as an 'apology' for ruining his chance to have hours of mindblowing sex with Rias. Looking back at it, Issei considered it more than a fair exchange, as he had instead soon fucked Grayfia silly. Yet even this was still only the start of what seemed to be a continuous series of sexual adventures and mishaps for Issei, whose life had changed so much in such a short time.

Issei thought Rias coming to see him in private to ask for Issei to be her first time had been a surprise, but it hadn't ended there. The very next day Issei and most of the rest of the Occult Research Club met a man named Riser Phenex, a tall handsome man a few years older than Issei. The two of them had disliked each other instantly, as Issei thought Riser was stuck up, and Riser as a Full-Blooded Devil found the idea of Issei even competing for Rias attention was a sick joke. So, with the backing of his all-female Peerage, Riser had challenged Issei and the others to a Rating Game, with the winner earning Rias' full and exclusive attention. Issei and the others had trained their hardest for ten days leading up to the challenge, but it simply wasn't enough. Spending more time having sex with new, attractive women all the time had drained a lot of Issei's focus, and Riser's team had won. The last thing Issei saw before he passed out was Rias' normally gorgeous face, twisted up into an expression of deep and harsh sorrow, tears streaming from her bright, large blue eyes.

Issei was asleep for just over two days after that, recovering in a healing coma, with only the memories of that Rating Game playing in his mind, over and over. He couldn't let this defeat stand. For one thing, Rias didn't deserve a life shackled to an unrepentant bastard like Riser, and for another, Issei couldn't let one of the sexiest girls he'd ever seen (which was saying quite a lot), with her perfect tits and amazingly fat ass, and someone who so clearly desired to be part of his harem, end up with anybody else.

Though these thoughts plagued Issei, it all seemed to leave him when he awoke from his coma, with physical sensation crowding out all his musings and worries. For starters, the simple act of being awake for the first time in such a long period brought with it all sorts of aches, pains, and newly discovered bruises and bumps for the ever-growing Harem King, things that took immediate concern. For another thing, and even more immediate, there was a loud series of slurrps in the room, along with a wonderful feeling of hot, tight wetness wrapped around his cock.

"What the-" Issei sat up as quickly as he could, which wasn't as quickly as he should've been able to, and threw the sheets aside. Underneath them, happily laying on the bed and throating his cock with an eager, brainless look on her face was Grayfia Lucifuge, completely naked. She was bobbing up and down quickly, drool leaking from the corners of her mouth and showed no signs of ever wanting to stop. It was only the sudden actions of Issei that made Grayfia look up, happily surprised.

Rather than stop, she began sucking on that cock faster and faster, wrapping her tits around the base of Issei's enormous shaft. He moaned at the sensation, Grayfia's mouth squeezing him tight as her cheeks hollowed out, her throat making exaggerated swallowing motions as her huge tits, more than twice the size of her head each, worked at a nearly frantic pace.

"Ahh…holy shit Grayfia, that feels amazing." Issei said, reaching down to grab Grayfia by her braids. She let out a little squawking sound as Issei began to thrust up into her mouth, fucking her face hard and fast. He pushed deeper and deeper, not stopping until every bit of his hundred and one centimeter cock was forced into Grayfia's grasping gullet. His balls bounced off her chin as Issei picked up speed, feeling a familiar tightening sensation in his large, swarthy and wrinkled balls, his orgasm getting closer and closer. Only a few minutes later, Grayfia let out a few high-pitched squeals and gasps, clearly having a hands-free orgasm while Issei dumped a massive load straight into her stomach. The sounds of his orgasm filled the room, Issei grunting like a beast, grinding Grayfia's face against his crotch with his death-grip in her hair, and Grayfia happily making her tits bounce and clap as moaned like a slut.

Spllrt! Spllrt! Spllrcch!

Issei lay back and basked in the ecstasy of his climax, feeling his body slowly awaken, joints unstiffening and his eyes blinking rapidly as he was now fully awake. And what a wake-up call it had been, though Issei wondered why he had come so quickly. His hands released Grayfia's hair, and she slowly, lovingly, withdrew from Issei's cock, her ruby red lips releasing his shaft with an audible pop!

"Ah…hello there, Grayfia. It's great to see you and all, only…how long had you been sucking my dick, before I woke up?"

Grayfia knelt in front of his cock, which was still rock hard and now shone with her spit. Her hands quickly went to work, jerking him off with just the right balance of a forceful yet soft grip and smooth, fast strokes.

"Oh, about an hour. I was told to come bring you something, but when I got here you were already nearly hard…which only makes sense, you having been asleep for so long. You must have gotten all backed up, with this magnificent cock just aching and begging for release."

Issei supposed that made enough sense.

"Well, what were you going to bring…me…oh fuck that's good." He moaned, unable to really hold a conversation at the moment. Grayfia was using every ounce of skill she had, the slutty MILF wringing more moans and gasps from Issei as she pleasured his cock with adoring, worshipful attention.

"Oh, that can wait for later. Right now, I've been waiting to do this for days." Grayfia stretched one leg around Issei's waist, rubbing her hands along his bare chest (Issei assumed he had been wearing clothes at some point, and Grayfia just decided to do away with them), lightly scratching him. Resting her ass against his stomach as she turned her body, Grayfia bent low, licking along the length of Issei's cock, slurping like the greedy slut she was. Then she slowly stood up, crouching above the pillar of Issei's dick as she faced away from him. She tossed her luxurious silver hair around her shoulders before she looked back at Issei.

"We've got some lost time to make up for, Issei~" Grayfia winked cheekily at him before she grabbed the base of his cock firmly, took a moment to steady herself and then-

Wham!

"Ooh, holy shit!" Grayfia said, as Issei moaned beneath her. Half of Issei's cock was buried inside Grayfia's tight, dripping pussy. Grayfia's face was a lewd ahegao expression as Issei's cock pushed a little deeper, tenting out her perfectly flat stomach and making her moan in a high-pitched voice. Despite having fucked Issei a few days ago, his cock was just so huge, so fat and wide inside her tight, pretty pink pussy that Grayfia could feel it rearranging her insides. Still, while Grayfia was new to handling Issei's cock, feeling it shift inside her and send electric jolts of pleasure racing up and down her spine, she was still an incredibly strong Devil. Every time she dropped her fat ass down onto Issei's hips she got a little more used to taking that cock, a little more stretched out.

Smack!

Grayfia bit back a shout as Issei slapped her far fat ass, clearly getting into the swing of things and looking more and more like his old self.

"Come on, Grayfia, you're the Strongest Queen, aren't you? So why don't you go a little lower?" Issei said, teasing her, even as he reached out to massage and grope her big fat ass. Grayfia began moving her hips from side to side, rocking on Issei's cock, knowing exactly what he wanted and how best to give it to him. His size was impressive, and while Grayfia's husband couldn't compare, the sexy older woman had still picked up plenty of tricks in her time. She took more and more of that cock inside the tight, dripping hot embrace of her pussy as she slowly began to turn around, eventually spinning right on that cock just as she lowered herself fully, impaling Issei's dick in her all the way to his massive, sperm-swollen balls. Issei and Grayfia both moaned at the wonderful sensation, as Issei's cock stood out in her stomach, the bulge of his dick so massive it reached up in between Grayfia's humongous, bouncing tits.

As Issei's hands folded up the bedsheets in pleasure, he could only watch as the sensual woman winked at him again. She was riding that dick as fast as she could, her legs tense as her ass swung up and down along with her breasts, the curvy woman's body showing off in all its glory. As she pleasured herself with his cock, simply using Issei's dick as a masturbation aid, Issei was tempted to simply lay back and enjoy the show. But as a Harem King, his pride wouldn't let him be so passive, not with a hot piece of ass like that spinning on his cock and showing off like that.

Smack!

"Oh, Issei, you naughty boy~" Grayfia playfully scolded Issei as he smacked her ass again, much harder this time. While he made Grayfia's enormous ass jiggle and wobble in an almost hypnotic fashion, he could tell it was barely a love tap to her. Much the same as when Issei leaned up, wrapping his arms around Grayfia's waist and practically feasting on those huge, perfect breasts of hers, sucking her nipples greedily, lightly biting her soft yet firm tits, all while his hands nearly mauled her big, perfect, heart-shaped MILFy ass. Grayfia moaned at the treatment, her natural abilities and powers so much stronger than Issei's that even his roughest treatment barely ruffled her in the slightest. In fact, she had to lower her defenses a bit so that she could feel him more properly, which Issei could tell. Maybe it was because he was still a bit groggy after his coma, or maybe it was because the taste of defeat was still fresh for him, but Issei decided it was time to kick things up a notch.

With a slight growl, low in his throat, Issei summoned his Boosted gear, the red gauntlet manifesting and locking into place on his arm. With a thought, the green gem began to glow as Issei boosted his strength to twice his normal level.

"Oh yes Issei, just like last time, fuck me hard!" Grayfia soon had her legs wrapped around Issei's waist , sitting down in his lap as he began to thrust upwards, taking more control of the movements between them. Concentrating on all the progress he'd made during training, Issei was boosting himself more and more, while Grayfia moaned and gasped louder and louder around his cock, losing herself in passion, raking her fingernails lightly across his back and shoulders. She was loving the way his hips smacked against hers, the way her body seemed to fit into his lap, their limbs working together in a sweaty tangle. Growing stronger several times a minute, Issei took advantage of the fact that Grayfia had lowered her defenses, and with one mighty swing he smacked her ass again.

Smack!

"Oooh-wahhh!" Grayfia let out a pleasurable cry of surprise, caught off guard but enjoying it all the same. Her ass was actually red now, and Grayfia tingled all over, feeling her body giving in to Issei, and remembering that first night of raw, wild passion they'd shared. Grayfia had long hoped to find someone who could keep up with her in bed-her husband, the poor unsuspecting fool, was nice enough, but far too gentle and certainly didn't measure up to Issei's size. With this young man, who had been an ordinary enough human only quite recently, Grayfia was quickly falling head over heels in lust.

Wham! Wham! Wham!

"Yes, Issei, yes, just like that! Really pound my married, cheating pussy, don't stop, don't stop!"

Grayfia felt like she was drowning in pleasure, with Issei sucking on her tits and spanking her ass, the ecstasy growing with each moment. She made sure to buck her hips against his, faster and faster, their bodies rocking against each other faster and faster. Moving as fast as he was, Grayfia was quickly losing herself as she felt Issei's cock twitch inside her. The massive bellend of his cock had been forced far past her cervix, which clung desperately to Issei's shaft, almost milking him. There was a surge of strength throughout Issei's body, and Grayfia almost doubled over, gasping, as that already enormous cock grew just a little bit bigger inside her, meaning he was about to come. As Issei grabbed a hold of Grayfia's ass, their bodies joined together as he began to come.

"Yes, give it to me, Issei, come deep inside me, fill me up!"

Spllrt! Spllrt! Spllrt!

Issei rocked deep inside her, feeling Grayfia squeeze along every inch of his dick. Grayfia's stomach bulged out as she was filled up with his hot, thick hyper-virile come. As Grayfia began to come down from her own powerful orgasm, Issei was still raring to go, his cock as hard as ever. He grabbed hold of Grayfia's bulging belly, reminiscent of pregnancy, which he may very well have fucked her into and flipped Grayfia over onto her side, fucking her in a spooning position. With how large Issei's cock was, Grayfia's hips were pushed to opposite sides, her legs pointed in different directions, moaning like a whore. She turned her head to one side as Issei was just there behind her, their lips meeting in a frantic embrace. Tongues pushing together, swapping spit and eagerly exploring each other's mouths, Issei thrust deep inside her, his hands roaming over her thick, curvaceous body.

Issei let out moans into Grayfia's mouth as they kissed, loving how good it felt to fuck this tall, sexy MILF bombshell, more experienced than Ross or Kuroka. While Issei bore no grudge towards Grayfia's husband, he couldn't help but feel a dark thrill from fucking her married pussy, knowing that marriage wasn't enough to keep a sexy woman like her from joining his ever growing harem.

"Mmm-mwah~ Oh god Issei, I love how huge your cock is, it's filling me up so fucking good, you're stretching me out like a cheap little slut!" Grayfia was normally such a refined, composed woman that Issei's heart raced to hear such debauchery from her lips, loving the way her body jiggled and shook as they fucked. Issei moved under her, turning Grayfia around and gesturing for her to lay flat on her stomach. Grafyia giggled as she rested her massive breasts on the bed, so large they ballooned out and were clearly visible on either side of her body.

"Fuck Grayfia, your ass is so goddamn huge!" Issei said, almost unable to contain himself. Issei grabbed and pawed at Grayfia's ass, wondering if it was somehow bigger than the last time he saw it or if it was just that impressive every time. He slid his cock in between her asscheeks, before he plunged back into Grayfia's pussy, so wet it was nearly frothing up as Issei thrust faster and faster. The bed shook and squeaked beneath the rutting pair, wobbling on its legs. It only now occurred to Issei that he was back in his bedroom at home, and he was determined to make sure he fucked Grayfia even harder than he had that first time, in this same place.

Issei loomed over Grayfia as he slammed into her pussy over and over again, feeling her body changing and wrapping around him so tight. Her womb was reshaped like a living condom around Issei's dick, and Grayfia reached back, spreading her asscheeks and shaking her booty for Issei. Going faster than ever, Issei's thrusts were ballsdeep now, burying himself inside her all the way to the hilt and then withdrawing, just shy of pulling out all the way.

After nearly twenty solid minutes of this rough, jackhammering prone bone position, Issei pulled out all the way, leaving Grayfia's pussy gaping. As she moaned underneath him, nearly delirious with pleasure, Issei changed the angle of his thrusts and then slammed forward with more force than ever before. His cock plunged into Grayfia's tight asshole, which he hadn't been able to thoroughly enjoy last time. Grafyia moaned beneath him, fighting back the urge to scream as her body thrashed. Grayfia bit the pillow in front of her, her legs going stiff as she came, her eyes rolling back in her head. Issei smirked, dropping his entire weight and every inch of his cock deeper inside Grayfia's tight, grasping asshole.

"Ahhh, holy fucking shiiiit!" Grayfia screamed, her words disappearing into a high-pitched shriek as she came even harder than before, her asshole and pussy having a simultaneous orgasm. Her entire body shifted and shook under Issei's thrusts, the bulge inside her stomach actually lifting her slightly from the bed. Issei thrusted deeper and deeper, practically digging a tunnel inside Grayfia's asshole. He leaned above her, biting Grayfia on the neck as she moaned below him, her tongue sticking out, a braindead expression on her face and her cheeks flushed, eyes rolling madly. Issei smirked, glad to have the advantage as he thrusted balls-deep again, leaving his cock there for a few long moments, making Grayfia's feet kick behind her, toes stiff as ecstasy burned through her mind.

Then, using his cock's sheer size, Issei pulled up, raising Grayfia up as she let out a low wail, unable to believe how her thoroughly stretched she was, the tall woman feeling like a living sex toy. Issei gripped her slender waist before turning her around, soon facing Grayfia while she moaned from the sensation of that cock nearly corkscrewing into her, feeling like her womb was permanently wrapped around Issei's dick as he spun her around. As they faced each other in a missionary position, Grayfia smiled up at him, her expression happy and hungry for more. Grayfia wanted him to ruin her for her husband and all other men, and Issei was happy to comply.

Boosting his strength further, Issei pulled out of her gaping ass, and Grayfia's eyes rolled while she tried to recover. With another powerful thrust, Issei slammed back into Grafyia's pussy, pushing them both along the bed. Grayfia's legs wrapped around Issei as he pushed her knees nearly next to her head, fucking her hard and fast in a rough mating press. Issei's cock was rampaging inside her pussy, slamming her womb so hard Grayfia saw stars with every thrust, feeling his balls smack off her dripping pussy lips and sensitive clit. She couldn't believe she was taking every inch of that cock with each thrust, making Grayfia's hands reach into the sheets, tangling them as she sought some sense of stability.

"Ooh, Issei, yes yes, just like that, right there!" She moaned, as Issei just smirked. He dipped his head in between her breasts, which were so large as to nearly make Issei's head disappear completely from view. He licked and sucked at the massive, bouncing tits, shaking his head rapidly and motorboating Grayfia's magnificent, perfect jugs.

"Fuck, I love your huge breasts, Grayfia! They're even bigger than Ross'!" Issei said, even as his cock was dominating Grayfia and making her squeal underneath him, he couldn't help but enjoy her curvy body with almost childish enthusiasm. His thrusts got faster and faster, while Issei soon lost control of his thrusts, picking up speed and intensity with each moment. Grayfia moaned in his ear, unable to form words as she came around his cock, squirting like a firehose.

"Aggh, I'm coming, Grayfia! Take every drop, you sexy MILF slut!" Issei said, slamming his cock balls deep once more. Twitching, his cock blasted Grayfia's womb with thick, pungent streams of jizz, enough to leave her nearly bloated with his sperm. Grayfia loved every second of it, her legs squeezing Issei a little bit closer, wanting their bodies to just grind against each other, as close as possible in a sweaty embrace.

"Mmm-mwah, Issei…god I love it, I love it so fucking much!" Grayfia said, mostly talking to herself as she covered Issei's face with kisses. She left bright red lipstick rings all over his face, from his cheeks to his chin, even as she greedily kissed him deeply, sucking spit out of his mouth and letting Issei's tongue push past her tonsils. Issei moaned into the kiss, even as his arms wrapped around Grayfia's waist.

With a sudden lunge, he stood up, barely having to lift Grayfia with his arms as his cock was simply dragging her up like a pig on a spit. Gravity did most of the work as Issei bounced Grayfia up and down, moving away from the bed and standing in the middle of the room as they fucked, his cock as hard as ever. With Grayfia's pussy still full of his come, her body seemingly desperate not to let even a drop slip out, Isseis' thrusts nearly frothed up inside the statuesque woman, churning her insides as his cock smashed past her gaping cervix again and again. Grayfia's arms wrapped around Issei's neck as he buried his face in her tits once more, fucking her like a wild man. Grayfia bounced back against him, her fat ass and eager speed nearly enough to push Issei backwards.

The pair roamed around the room, fucking against the walls, with Issei holding her close to him in the air and slamming away, and even letting go of her waist so he could better grab and squeeze her tits, leaving her imapled on his cock. Eventually, Grayfia rocked back against him as Issei stood near the bed, causing him to fall and land on his back, the bedsprings bouncing. Grayfia didn't miss a beat,and was soon riding Issei like a dirty cowgirl, faster and faster as she was going crazy on that dick.

"Oh my, Issei! I guess, I don't know my own strength, hee-hee~" Grayfia giggled like a schoolgirl as she bounced on that cock, going faster and harder. Soon not only the bed was shaking, but the entire house. Issei felt Grayfia's pussy clamp tightly around him, knowing that she was so horny and pent-up, after having been married for so many years, that she was clearly losing herself in the pleasure. If Issei hadn't boosted his strength so much, the horny curvy slut probably would have broken or at least bruised his hips with her big fat ass. Not that he was complaining, loving the adrenaline pumping through his veins from the rough, dynamic sex. He spanked her ass forcefully, which made Grayfia coo and moan, happy to finally found someone who could keep up with her sexually. The pair were soon matching the other's movements, moving in synch as their hips smashed together rhythmically, neither showing any signs of stopping.

Unnoticed by them, the door cracked open slightly, followed by a small girl pushing her way inside. It was Asia Argento, wearing her typical nun-style outfit with her long blonde hair cascading down her back, green eyes wide.

"Ah, Issei-san, are you finally awake? I think there's an earthquake nearby, we need to get you somewhere…" She trailed off, in awe at what she was seeing. Issei was fucking that Lucifuge woman, whom she knew only by reputation…and the two of them were like wild animals. Rutting madly, Asia watched as Grayfia worked her way up and down Issei's cock, which looked to be more than half as big as Asia herself and nearly as wide as her waist! Issei had no idea she was there, but Grayfia dimly noticed the blonde girl, and promptly ignored her. Rather than be startled, she just kept focusing on the pleasure of that huge dick in her dripping pussy, and was riding Issei even harder.

Wham! Wham! Wham!

As the house shook around them, Issei slammed up into Grayfia's cunt just as she dropped herself into his lap, hard. The pair reached climax at the same time, with Grayfia shaking violently on that cock, her pussy spraying out like a hose while Issei filled her already stuffed pussy with even more hot, nasty sperm. Grayfia could feel it stretching her out, drowning her fertile ovaries as she shook, and then collapsed against Issei's chest for a moment, breathing hard, her cheeks red and sweaty.

Asia knew she should either leave or say something, but she remained standing in the doorway, until a shadow fell over her. She gleaned up and saw Rossweisse walking into the room, no doubt drawn by the noise of loud, rough fucking. As one, Grayfia and Issei looked to the door, seeing the silver-haired Valkyrie and the petite, tiny Asia.

"Looks like we have company, Issei~" Grayfia teased, lightly planting another kiss on his collarbone.

Issei, who had only been awake for a few hours and fucking the whole time, was a bit slower on the uptake. "Ah, big sis Ross! What are you doing here? Grayfia came by to give me something, she said and then–"

Rossweisse cut him off, dragging Asia along by one arm and whispering to her.

"This isn't a spectator sport, little girl." Then her attention turned to Issei as Rossweisse began to strip, removing her teacher apparel and revealing the black lacy lingerie she'd bought specifically for Issei.

"And you! Ten days on that training trip with Rias and her friends, and the first thing I see you doing when you're back is fucking another woman? She better not have drained you completely because you and I have a lot of catching up to do, young man." Rossweisse's tone was playfully scolding, knowing Issei couldn't help himself around a big pair of tits, a nice ass, and a pretty face, and Grayfia clearly had all three. Likewise, Ross wasn't surprised to see such a gorgeous woman doing her best to fuck herself stupid on Issei's monster cock–that had more or less been her reaction that first time, after all.

Grayfia smiled at Rossweisse, slowly stepping off of Issei's cock, her legs weak and wobbly. She didn't know this Rossweisse, though she'd heard Issei talk about her before, and what she saw, she liked.

"Sorry, Ross, I didn't realize I'd be gone for so long…the Rating Game didn't go exactly as I'd hoped." Issei sat up as Ross crawled onto the bed, kissing him deeply. One of Ross' slender hands began to jerk Issei's cock, tugging him off with fast, smooth strokes due to all the jizz and pussy juices still clinging to his cock. Grayfia worked with her, sliding low on her belly and wrapping her huge tits around Issei's cock. Rossweisse couldn't believe it, but her tits were so massive they covered more of Issei's cock than Ross ever had herself, just over half of his dick disappearing into Grayfia's mountainous cleavage.

"He's so much bigger than my husband, it's insane!" Grayfia said, as Rossweisse joined forces with her, stacking her own breasts right on top of the MILF's. She responded to Grayfia, beaming up at Issei.

"Well of course he is. No one can compare to Issei and his Dragon God cock.♥"

Soon Rossweisse and Grayfia were soon kneeling in front of his cock, working him up and down with their huge tits, feeling the weight and heat of his dick radiating through their entire bodies. As Issei watched, nearly spellbound, as they began kissing and licking at his cock, their mouths pressing together. Soon they were bouncing and clapping their tits around his cock in rhythm, squeezing Issei up and then shaking their tits rapidly as they swung down. Rossweisse kissed Grayfia lewdly as they slurped on Issei's massive bellend, leaving spittle dangling between their lips in thick, cloudy bubbly ropes. Issei moaned from the intense treatment, though his eyes couldn't help but drift over to Asia, still standing in the doorway like she was frozen in place.

Asia knew she was attracted to Issei, and she knew (a little) about sex. But she'd never expected anything like this…Rossweisse-sensei was making out with another woman, who she knew as Rias' maid, while also sucking on Issei's massive, enormous, throbbing cock. The sheer size of it shattered Asia's grasp on reality, so unlike anything she'd ever imagined or thought possible. The blonde girl also couldn't help but notice how well-endowed the two older women were as well, knowing that Issei was a sucker for big boobs, they seemed to drive him crazy and make him stupid at the same time. While Asia was never the type to say an unkind word to anyone, as she watched Rossweisse climb on top of Issei and ride his cock in a reverse cowgirl position, she couldn't help but feel a twinge of repressed jealousy. It didn't help that Issei was motorboating Grayfia's huge tits, before the silver-haired woman slid between Issei's legs and began licking at his huge balls as well as Grayfia's pussy, the three of them seeming to know what to do as if by instinct, communicating largely by loud, crude, animalistic grunts and moans.

Asia barely knew how to respond to all of this, or how to even think. But her feelings for Issei weren't new, as he treated her not as a saint, or heretic, or see her as a tool due to her Sacred Gear, he truly seemed to see her for who she was and like her that as well. In the past, Asia had asked some of the other girls, Rias, Akeno and Aika about how best to demonstrate those feelings. While their advice had been…mixed (and downright shocking in the case of Aika), Asia knew what she had to do, what she wanted to do, deep down in places she had never even thought about until meeting Issei. And while his cock was so large it honestly frightened her slightly, she'd be lying if she said it didn't also make her heart beat faster, her cute face flushing a deep red.

She glanced down, taking a look at herself. While attractive, in her way, Asia was definitely more on the 'petite and cute' side as opposed to Grayfia, Ross, or even Rias who were all…'stacked' as Aika put it. Asia closed her big green eyes, concentrating as she thought of the sorts of women Issei liked, their bodies, and how her own measured (or didn't, in this case) up.

"Oh fuck yes Grayfia, suck my balls just like that, fuck, even Kuroka couldn't fit both in her mouth at once…eh?" Issei said, looking away from the sordid sight as a bright green light filled the room, eventually attracting the attention of Grayfia and Rossweisse (who squirmed as she sat all the way down on that cock, feeling Issei's dick bulge her stomach out and force her tits apart from within) as well.

"Asia, w-wow! You look amazing! I mean, you always look good but…wow!" Issei babbled, taking in the sight of the new and improved Asia. Her outfit was ripped across the chest and around her ass, which had both more than doubled in size. Her tits were as big as Rossweisse's but seeming even larger with how petite Asia still was. Though as she walked towards the bed, all that ass clapping and shaking behind her, swallowing up her white panties easily, it looked like Asia was a little taller than before, though still quite shorter than Ross and Grayfia. Clearly her Sacred Gear had evolved a bit, not so much healing as enhancing her body to levels that made Issei's eyes glitter with yellow sparkles.

"Ah, Issei. I just wanted to be a good…comfort woman for you. I want to show you how special you are to me, and make you feel good~"

"Well come on in, then Asia. The more the merrier!" Rossweisse said, and Grayfia mumbled similar positive words, though her mouth was still muffled by one of Issei's massive testicles.

Asia was completely sexually inexperienced, but she figured the best way to learn anything was from those who knew more than her, and the two older women clearly fit that description. As Issei watched, Asia gently interposed herself between Ross and Grayfia, as Rossweisse slowly climbed off Issei's dick. Soon all three girls were giving Issei a lewd, sensual titfuck, with Asia stacked on top of Ross and Ross on top of Grayfia. Pushing her breasts together firmly, till they puffed out around her little fingers, Asia tried to stuff as much of Issei's dick in her mouth as she could, though she could only manage a few inches. Still, she began furiously licking at it, making up for her lack of skill with raw enthusiasm and passion.

Issei gave Asia a strange look, seeing her in a new light, while Grayfia and Ross nudged each other, eyebrows raised. Who would have thought Asia Argento was hiding such a slutty side? But as Ross had thought before, Issei just brought that out of women. After all, who could resist such a handsome boy with such an incredible cock? As Issei lay back, enjoying the oral and titwanking he was getting, Grayfia and Ross silently encouraged Asia to go a little deeper on that dick, to lick a little faster, to squeeze her now massive jugs in just the right way, simply by doing it themselves first and giving the eager girl an example to follow. Issei moaned at the combined attention of all three women, their breasts feeling like heaven wrapped around his cock, with Asia's tongue sticking inside his wide urethra as she let out cute little gasps around his cock, vibrating the huge shaft.

"Hahn…so good! Ok girls, it's my turn." Issei said, and his three gorgeous harem girls happily moved at his instruction, with Asia laying flat on her back, quickly divested of the rest of her clothes by Ross and Grayfia. Issei crouched down, licking at Asia's virgin pussy before he began softly sliding two fingers inside her, slowly at first. She moaned, letting out little squeaks and gasps, feeling pleasure she'd never imagined before. Her back arched up off the bed, her legs trembling and naturally closing slightly around Issei's face.

As Issei pleasured the formerly skinny girl, Grayfia lay behind him, licking at Issei's sweaty pink asshole. She loved the way her tongue made his body seem to jump and shiver, pushing a little deeper and letting out a lewd, happy moan to herself. Rossweisse was doing her best to swallow Issei's balls, sucking first one and then the other, hollowing her cheeks out as she lathered spit all over those huge nuts, her pussy absolutely gushing as she huffed Issei's ball musk like a drug.

"Ah, Issei, that feels…amazing! My body feels like its burning up, oh Issei! Issei!" Asia gasped, her voice breaking off into a high-pitched, raspy series of moans as she came hard, her juices running down Issei's lips and chin as he kept licking greedily at her pussy, fingers pushing in and out relentlessly. As Asia came down from her first orgasm, Issei scooted forward, making Ross and Grayfia follow behind as though they were chained to him. Slowly Issei raised his huge cock and brought it down on Asia's pussy, with enough force to send a shiver run through her body, an aftershock of her orgasm arcing up her spine.

"I can't believe your Sacred Gear could do something like that, Asia. But…why did you do it in the first place?" Issei slowly pushed his dick forward, ever so gently nudging at her pussy, which despite a bit of stretching still seemed impossibly tiny.

"Ahh, hah…I wanted to be the kind of woman you liked, Issei. Because…because I love you, I've loved you ever since the day you rescued me. So please, use my body as you wish, you've already made me feel so good, I just want to please you as well!" Asia's eyes were brimming with happy tears as Issei moved forward, ever so slightly beginning to penetrate her with that enormous cock. Asia moaned, her eyelids fluttering as Issei pushed in a little deeper, working slowly.

"Asia…I don't want to hurt you, but I do want us both to feel really good. So I think I have an idea, I'm gonna just try something ok? Just, trust me." Issei said, activating his Boosted Gear to a higher level, gaining a second green gem and more golden spikes as it elongated down his arm.

"Yes, Issei, I trust you, whatever you say!" Asia said, before she felt something warm spread throughout her entire body. It was like her own Sacred Gear and the ability she'd just used to enhance her body, only she could tell this power was coming from Issei himself, sharing energy with her in waves of warmth that made her pussy lips seem to relax slightly, swallowing that dick up more as Issei leaned above her, pressing a bit more firmly with his hips.

Asia's breasts were now even larger than Grayfia's, and her ass made Rossweisse look flat in comparison, while her eyes gained a deeper, inner green light. Asia stared down at her new body in wonder, lightly squeezing her breasts experimentally, moaning at the pleasure that ran through her, feeling tingles all over. Clearly her sensitivity had increased along with her size, and she was taller now too, even taller than Grayfia.

Feeling like he had a bit more room to work now, Issei thrust forward, watching the bulge inside Asia spread upwards. She moaned deliriously underneath him, shaking and trembling as she came again and again on that dick, her body stretching on the inside, each inch of Issei's seeming to light up new spots of pleasure in her brain. As the bulge traveled nearly up to her neck, Asia weakly pushed her tits together, working to give Issei a titfuck from the inside. His hands soon joined her's, squeezing those new amazing tits of hers. Issei used one arm to push Asia's legs upward, fucking down into her pussy at an angle in this new rough mating press position.

"Oh, Issei, I'm coming! I'm coming all over your huge dick, it feels too good…I'm melting!" Asia shook her head from side to side weakly, her hands grabbing at her own face. Issei leaned down, kissing her lightly as Asia's eyes slowly closed, happy tears forming once again. She gingerly returned the kiss, a chaste embrace between the two that was in marked contrast to how deep Issei was fucking her, his cock stirring her insides up.

Wham! Wham! Wham!

Asia lost all track of time, thinking Issei could have been fucking her for minutes or perhaps hours, only knowing that she was coming over and over again on his huge, magnificent dick. She babbled in his ear about how incredible he was, how amazing his dick felt inside of her, how she wanted to have sex with him every single day for the rest of his life. Finally, after building up a good pace, Issei felt another orgasm approaching. Slowly, almost agonizingly, Issei pulled out of Asia's pussy, leaving her trembling and gaping. Stifling a moan as Grayfia and Ross both feasted on his fat nuts, Issei tilted his cock down slightly and punched forward, spearing his dick into Asia's tiny virgin asshole.

"HNNNGG!" She screamed, unable to form words as her body was stretched open in new, amazing ways. Thanks to her own Sacred Gear as well as Issei's, she could take such punishment, but while her body could handle it–barely–her mind could not, and the pleasure threatened to overwhelm Asia. She babbled that she was coming again and again, eyes rolled up in her head in an embarrassing, flushed ahegao expression. Asia was discovering how amazing sex could be, thanks to Issei and his godly cock, feeling him angle his cock a bit differently and hit a whole new spot in her ass, making her heart skip a beat as she trembled. Bright pink hearts shown in the eyes of the former nun turned devil and now, slutty and eager ass-fucking harem girl.

"Fuck your ass is so tight, Asia, it feels like it's trying to suck my cock inside and never let go! You really are one sexy, dirty little slut, huh?" Issei teased her, kissing along her neck as he kept up the slow, deep strokes he was fucking Asia's ass with.

"Yesss~" She hissed, drool leaking from her mouth. "I'm a slut, I'm a dirty slut, I'm your slut ♥Issei!♥"

Almost ten anal orgasms and half an hour later, Issei slowly pulled out of Asia's ass, while she moaned underneath him. His cock was so large, so wide inside her that Asia felt like he'd fucked her guts up permanently, but she didn't mind in the slightest, even thinking that he might fuck her inside out. Issei climbed on top of Asia, shoving his cock between her enormous tits and then thrusting forward. Like a good little dicksleeve, Asia opened her mouth wide, even reaching up to fishhook herself with both hands, tongue out as she let out an eager little 'ahhh'

"Gllch, glagggg, glawwk!"

The sound of gagging and rough, wet sloppy facefucking filled the room again as Issei fucked the stacked blonde's throat and tits. Grayfia and Ross got up on their knees behind Issei, hugging him close and squeezing his head between their tits. Barely able to see anything else, Issei motorboated the enormous two pairs of tits while Grayfia and Ross encouraged him not to hold back, to give in to the heavenly embrace of their tits and use Asia like a good little whore.

With a series of high-pitched moans, Issei kissed, licked and sucked at their breasts like there was no tomorrow, beginning to come at the same time. With a series of loud, nasty splrrrtts!, Asia was forced to swallow enough cum to fill her stomach several times over, feeling her new taller body barely able to keep up with it. Jizz backed up in her throat until it finally exploded out of her nose, coating the base of Issei's cock as he held himself deep inside her gullet, body trembling with pleasure.

Pulling out, Issei spun Asia around, pushing her down on his cock in a cowgirl position. Her huge ass seemed to wobble in the air as it bounced and clapped, making Asia's tiny waist look even smaller and giving her a slutty, impossibly curvy hourglass shape. Asia's pussy felt like it was taking Issei's cock for the first time all over again, the angle making her naturally tighten up around him.

"We can't let Issei have all the fun, can we Ross?" Grayfia said, and Ross simply smirked, shaking her head. As Issei fucked Asia in this new position with the blonde girl squeezing and moaning, reaching back to grab her own fat ass and lift her cheeks for Issei, Grayfia and Ross knelt in front of her. They began licking and kissing her newly enhanced, very sensitive breasts. Asia gasped, feeling sparks explode behind her eyes at even the lightest touch of Grayfia's talented hands or Rossweisse's wet, grasping lips. Ecstasy coursed through Asia's body as Issei fucked her over and over again with swift, deep strokes.

"I-Issei, I want you to come inside! Fill me up and…get me pregnant! I want to have your babies, please! Breed meeee!!"

Asia screamed her head off as Issei's thrusts only picked up in speed and intensity. His cock shifted inside Asia's body, the bulge now visible in the bottom of her normally swanlike neck, distorting her words as she tented her out, before pulling back as he began to come. His hyper virile ball batter hit Asia's womb with such force that it nearly bruised her internally, each shot feeling like it was forcing the air out of her lungs as she came over and over again on that cock. She was almost certainly getting pregnant, her eggs surrendering to the superior sperm of Issei's God Dragon cock, just feeling her ovaries pop out one egg after the other much like her brain cells seemed to be exploding and frying inside her head.

As Issei slowly relaxed, Rossweisse leaned forward, waving a hand over Asia's enormous belly. "Here, let me."

She traced a pattern of runes in the air, which suddenly glowed with blue light. In seconds the sperm filling Asia up vanished, revitalizing her new strong and tall body. Asia gasped, while Grayfia sounded intrigued.

"That's some impressive magic you've got there." She pointed out, though quite comfortable with her own powers. Ross winked at her, before sparing Asia and Issei a glance.

"Well, I need all sorts of tricks to keep the father of my kid happy."

Asia and Grayfia were both surprised by that, their jaws almost hanging open comically. Issei was also surprised, though perhaps not so much–it only made sense after all, given how many loads he'd fucked into Ross since that first night. In any event, his response was a bit different, as he pulled out of Asia and then pushed Rossweisse onto her back. As the Valkyrie lay back, Issei kissed and sucked at her huge tits, forcing her legs up till Ross' toes were pointed towards the ceiling.

Wham!

Issei smashed into her tight pussy, fucking her fast and hard, his arms wrapped around her back and keeping her legs locked in place. He'd basically turned Rossweisse's elegant and lithe body into a pretzel, twisting her up like a fucktoy for him to use to his heart's content. Grayfia and Asia were still reeling from the surprise, but they were also horny as hell and very turned on by watching Issei fuck another slut. As Issei ravaged Rossweisse's pussy, they happily leaned above Isse, keeping their wet pussies above Ross' face as the two of them sandwiched Issei's head with their breasts, keeping all four of them in ecstatic bliss.

From there, things only continued for quite some time, as the foursome found more and more ways to enjoy each other. First, Issei was fucking Rossweisse as she rested on her hands and knees, saying she wanted Issei to fuck her like a bitch in heat, As his cock slammed in and out of her ass, distending her pink asshole and fucking up even her tough, Valkyrie guts, Grayfia knelt beside Issei. She kissed him deeply, one hand rubbing the lean muscles of his chest as the other dove in and out of her pussy, masturbating like crazy. Nearby, Asia was babbling to herself while Rossweisse ate her out, going so far as to grab a pillow and bite into it to keep from screaming. There was a cute yet crazed expression on Asia's face as she squirted, unable to resist the pleasure in anyway and even more of a slut than many of the other girls in Issei's harem.

A bit later, Issei thrust upwards into Asia's throat, fucking her face while the tall and enhanced slut greedily gulped that dick down. As she stood up, bent at the waist perfectly, Grayfia and Rias twerked their fat asses right next to Issei's cock. Both of those big fat booties were jiggling jelly as Grayfia and Ross leaned closer, their asscheeks spread wide open due to how fat Issei's cock was. Pushing herself down deeper, Asia's gagging and choking sounds joined the chorus of claps from those fat, round, juicy asses until her pretty pink lips nearly brushed against them, both Grayfia and Rossweisse actually smothering her a bit with all their ass.

"Oh yes Issei, just like that, really fuck my pussy up! I want to bear your children too! Fuck my cunt as hard as you can, make my worthless husband a fucking cuck!" Grayfia shouted as she rocked back and forth on Issei's cock in a somewhat standing reverse cowgirl position, swinging her butt up and down for Issei to stare at. Rossweisse and Asia soon muffled Grayfia with their tits, something the noblewoman as they made out.

"Mm…mmmwah…I guess this makes us sisters now, right?" Asia asked, cutely. Rossweisse's only response was to laugh and then go right back to shoving her tongue down Asia's throat. The other girl squeaked as she leaned into the kiss, overjoyed.

"Schllurp, schlooorp!"

Grayfia and Ross were each sucking on one of Issei's balls, able to swallow one huge, hairy testicle each. Issei moaned at how good it felt, fucking Asia in a standing full nelson position. Her legs were locked behind her arms, folded up and fucked like a sextoy, being shown that even in her new and enhanced form, she was still no match for Issei. It just reminded Asia of what she already knew–that Issei truly was an amazing boy, and she was happy to get any and all treatment from him.

"Yes, Issei, yes yes! Fuck me harder, I can take it, I promise! And if I can't…you can just force me too, daddyyy!!" Her voice cracked as she came again, spurred on by Issei's thrusts and also Rossweisse, who licked Asia's tiny asshole lewdly.

Some hours later, the four were all relaxing. Asia rested to the right of Issei, Ross to the left and Grayfia in the middle as they took turns sucking and deepthroating Issei's huge cock.

"So Grayfia, what did you come to bring me, anyway?" Issei asked, only just now remembering. Grayfia thought for a moment, sucking on Issei's cocktip like it was a tasty candy treat. She had also forgotten until just now.

"Oh yes, a paper arrived, a potent spell scroll. It has an inverse summoning spell on it, so you can use it to bring yourself to Rias' wedding ceremony with Riser and save her."

"Hell yes!" Issei said, losing control of himself for a second. He began to flood Grayfia's mouth with sperm, forcing her back down onto his cock with one firm grip on the back of her head.

"The President's glorious ass should be mine, that's what she wants and it's what I want! I'll deal with that Riser, one way or another." Issei glanced down at Grayfia, who was snowballing his jizz with Asia and Rossweisse, their lips smacking as they happily giggled and played with the stuff like brainless bimbos.

"When is the wedding, then?"

Grayfia thought for a moment, gulping down Issei's sperm and slurping a stray pubic hair up into her mouth like a vacuum. "Tomorrow night."

Issei smiled, grabbing hold of Grayfia's head again. He began thrusting as fast as he could, making Grayfia gag even as he made her take the entire length again and again.

"Well that's plenty of time, and I''m still not satisfied. Looks like we've got some time to kill before the wedding then." Grayfia let out a little 'glurk' of approval, all while Rossweisse and Asia watched, eagerly awaiting their next turn.
