Chapter One- One Very Heated Afternoon Full Of Dragonic Lust- (Issei x Rias Gremory, Koneko  Toujou)

****

Following the original timeline of events in the DxD universe...

Ever since the events following the latest Ratings Game match between the Gremory Peerage and the likes of her rival, Sona Sitri, Rias Gremory had started a burgeoning life of sexual deviancy and uninhibited behavior with her equally virile partner Issei Hyoudou. Their love had blossomed from as far back as when Issei defeated Riser Phenex in the challenge for the Rematch of Kuoh's Rating Game loss some time ago. The chance to do so was granted to him by the girl's older brother and following that humbling beatdown, Rias was finally free from the arrangement of her marriage to be with Issei and her Peerage once more. For a little while at first, not much had happened between the two for they were still coming to terms with their feelings for each other amid the nonstop chaos of their everyday lives serving as Protectors of the human realm as well as operating as 'Devils for Hire' for any who would seek a contract with them. It was just as business as usual, but with the everyday chaos of having either Akeno, Asia, Xenovia or any other girl practically throwing themselves at Issei out of mutually obtained affection for the young horndog. The temptation to indulge in their 'offers' had always been piling on to the point where the Red Dragon Emperor had to hold himself back for the sake of his Harem dream being realized. The irony was that he could have it right there by giving in to each girl's advances first and letting a love nest of horny women begin with a large number, but while Issei had always aspired to have that goal fulfilled, he had also fallen in love with Rias first and wanted to marry her as his wife before he could. Until then, the young man had to endure many pairs of large buxom breasts being glomped onto his face whenever the girls dogpile on him or tackled him onto his bed. Be it Koneko's perky mounds or Akeno's and Xenovia's large pairs of head-sized tits, some girl's chest was always pressed into Issei's body and made him nearly give in to his increasingly repressed lust right there on the spot. Somedays it was even worse for his libid such as Xenovia constantly asking him to breed her or when Irina decided to confess to Issei that she always wanted to sleep with him during their earlier days of becoming part of Rias Gremory's Peerage. Everywhere, all at once inside of the main building or in the 'main base' that is the clubhouse, Issei was thrown into temptation constantly and resisted for the sake of giving his first time to Rias while also somehow obtaining his harem all at the same time. These pent-up urges of lust that were now directed toward all the girls around him had built up ever since he started to repress them till the day Rias and Issei finally became an item together.

The two hadn't decided on marriage yet despite everyone seeing it as an inevitability at this point, but the idea stayed in their minds for the future. After they had left Kuoh for a little while to travel to Kyoto as well as supernatural worlds beyond, Rias became every bit as eager to indulge in sex as Issei had once been. They indulged in mutual pent-up sexual tension between each other starting with Rias giving herself to him now and then between performing their duties to their clients and safeguarding the mortal realm from Fallen Angels and rogue devils alike. Even inside the clubhouse or within Kuoh itself, Rias would often demand that Issei drop his pants and take her from behind over her desk in the main office room. To the surprise of the horndog, she would even turn invisible in public and get down on her kneecaps to start sucking him off when out in the city to hand out flyers. Of course, she used a spell to make herself invisible, but that did nothing to deter the spice of this spontaneous act of deviance from the Princess of Ruin. She'd even spice things up by smothering her breasts around his absurdly large rod just to see Issei making that face to any passerby and get excited from the raunchiness of it all. Rias knew that Issei liked women's breasts very much and made sure to always give him a combination breast job and blowjob whenever possible, be it outdoors or inside the main building when no one else was around. It made Issei virile and as excitable as a wild animal on the prowl to have this treat nearly every day, so much so that a certain 'change' was blossoming forth inside of him without either of the two knowing. But Rias picked up on something odd about Issei's behavior at one point during one of their trysts due in part to her knowledge of Red Dragon Emperors of the past. She felt that somehow he was holding back his truer self despite getting everything he wanted out of her supple, soft, buxom body repeatedly pressing against his in acts of pleasure. Issei had not yet fully acclimated to the raw power of his Gauntlet from what she'd seen and theorized a while back, but she initially wrote that uneasy feeling off as suspicion and needless paranoia. Since then, she simply continued to smother Issei with love and sexual affection by massaging his cock strongly from between her breasts until he'd be ready to explode within her mouth or all over her face.

While they would often go at it like a pair of horny newlyweds channeling all their pent-up passion for each other in many creative ways, Rias would be unaware of Issei's true libido about to surface now that his pent-up urges were reaching a boiling point despite all their times together as lovers. Being the Red Dragon Emperor came with more than a few Quirks that one would call 'chaotic' and she was about to see it for herself soon enough when a certain and rather special 'affliction' came over her dear boyfriend one day.

It was a day like any other where a particularly distressed Issei came to his lover's room yearning for more than just the usual 'mild' bouts of sex. He needed to breed and breed Rias right now in ways only a Dragon Emperor would.

....

******

On an evening one day just outside of her mansion where the entire Peerage of Gremory, which was just her large group of highly cherished friends, had come to stay over during a weekend vacation in the Underworld, Rias Gremory looking out at the balcony of her bedroom with eyes centered on the night sky. She had been wearing a modest yet highly sexual sleepwear lingerie consisting of a simple see-through lampshade of ruby color stemming from below her lace brasserie top with a matching red-lace thong worn over her sex below. Her long, full legs were draped in elegant see-through stockings of red fabric and attached to a pair of tiny garters connecting to the highly seductive lace garter belt around her waist. Her bust was sticking out more noticeable than before as the brasserie was barely clinging to the pendulous shapes of her breasts. Her figure remained every bit as sublime as it always did with her sensual curves and hourglass figure shape which would be kept in shape forever thanks to her Devil genes. Rias was a beauty among beauties and will forever be one in the eyes of a certain 'Legendary Pervert' she fell in love with as far back as when she first saved his life. She was currently looking up at the dark horizon of starry skies beyond the stratosphere of the Underworld with a tender smile on her face and gripping the railing of the balcony tightly for she was feeling red hot with needs. The young woman was blushing a color as brightly as her beautiful, blazing mane of hair was red for she was hoping for Issei to come here right now for the usual carnivorous round of sex tonight. She was in a far stronger need of it than ever for some reason and she could hardly wait till she heard him knocking at her door. 

"Ooohh, he'll be here any minute now, I just know it. I want Issei to just ravish me like before and do it as the darling Gentleman I've come to know him as. He'll be here very soon, my intuition has never betrayed me in this manner and my boyfriend never disappoints, heheheh.  I wonder what seeing me like this will do for his libido since he was already so fired up for sex to begin with, but I've always worn less seductive clothing during the first dozens of times we've done it. This'll make his penis fly off of his body before he lunges at me like some wild beast, ooohhh...I can hardly wait indeed....!~" Rias said to herself in thought, twisting a lock of hair around one of her fingers and whistling to herself nonchalantly till she decided to go back inside to wait on her large Queen-sized bed for Issei to arrive. She already knew his patterns by now to have anticipated when the horndog would show up before her, feeling moist and eager down between her legs already.

Knock knock knock..!

"Ah, that's him...! I know it! Ahem...I'm coming, Issei-Kun.~" Rias said aloud, feeling giddy as can be as she practically hopped off the bed and skipped her way over to the door in a girlish fashion. She was wishing to surprise Issei by hiding behind the door's surface when she suddenly felt something was off after hearing a rather feral sound coming from beyond the other side of the door.

...

Grrllggghhh..!

"Hm? Issei? Is that really you back there?" Rias asked carefully, narrowing her eyes in slight suspicion and remaining aware in case this was some kind of surprise attack by one of their enemies. Carefully taking a stance behind the door and preparing to fight back with Magic using her right hand to begin glowing with power, Rias reached forth to undo the magical locking mechanisms on her door before pulling it ajar very slowly. She peeked over the edge from the side to see that it was indeed Issei himself and no one else. This was making her relax a little till she felt something was wrong as she saw that he was hanging his head low and breathing rather loudly in heavy huffs of air. 'Something...appears to be very wrong with him. I wonder what it could be. Issei couldn't be sick or under the influence of some spell, could he?'

She dispelled the magical power in her hand and pulled the door open all the way, relaxing somewhat as she saw him heaving rather strongly like some wild beast and leaving a bit of drool to escape the corners of his lips when his head rose higher to meet her eyes. Issei's normally cheerful, energetic green orbs were looking dilated as though he was in some kind of trance. He was wearing his usual clothing consisting of a red T-shirt worn underneath a darkened jacket and a matching pair of pants, yet he was slightly hunched in his posture and showed Rias his eyes were now glowing red once he had her in his sight.

"Rias...! I..must...have...it....now..! Grrhgllll! I..must....take you...and breed you...!!! Rias...! Rrgghghghhhhh! Help....me...! These urges..just..came over me...today...! It all hurts...to control...unless I let it out...somehow...aarrghghhhh!" Issei howled loudly before stomping into her bedroom and frightening Rias as she was backed into the edge of her bed. She remained standing upright and clamped her hands around his shoulders in support, eying Rias with concern for this was some kind of malady she had never once seen afflict any other person in her life.

"Issei..! Talk to me..! What is wrong...? I should perhaps call Rossweisse or my brother to help. Maybe they can see what this affliction is and help identify whatever's happening to you at this moment, Issei. You are looking rather unwell, pent-up even...dare I say....almost feral..." Rias pointed out and held onto Issei before guiding him to her bed. She sat him down and tried channeling some of her magical energies into her palms in hopes of detecting whatever influence there was over her boyfriend. He was not only pale but also obviously stressed out to the point a few hairs were out of place all over his face. His eyes roamed all over Rias's half-naked body wearing such insanely provocative lingerie when his lustful instincts started to kick in with a strong lurch of bestial impulse. 'Hmm, he seems completely normal. Maybe he's just worn out from the trip here. No, that couldn't be right. Issei-Kun is always full of energy and he's continually active as far as libido was concerned, always coming to me for sex whenever possible. So what could this be?'

!

"

Suddenly Rias was starting to feel dizzy with pleasure and sensitivity with some kind of pleasant sensation that made every touch of skin between her fingertips and Issei's body feel electric. Her body started feeling hotter and her breasts felt as though a single brush of his fingertips would make her shudder with sensation. Her tits were always the weakest, most sensitive part of her body other than her mound and right now Rias was feeling everything light up inside of her the longer she was within a breath's hair from Issei's face.

"Haaaah...! Ooohhhh..! What in Satan's name..? Nnhmgnh....! Issei-Kun, something...is affecting me right now. Right after..... touching you.  Oooooghh..! Your scent....your....presence, everything about you is driving me crazy just by proximity alone! Uaaahh....!~" Rias let out a jittery mew of elation as the effects of his undiscovered Pheromone field decided to kick in with full strength with Rias within perfect range of it. It'd start to grow steadily larger the stronger the Red Dragon Emperor's urges felt and without Issei willingly engaging it. His crotch started burgeoning strongly from inside of his pants and his breaths were becoming terse with focused need as he continued to eye Rias with a predatorily hungry look in his eyes that she had never seen before. Issei had always been a horny go-getter, but he never outright looked like he wanted to eat Rias alive as he does at this moment. While grinning lasciviously at her, Rias's eyes widened with realization as she recognized what this is at the moment Issei stood up and held onto her waist with both sets of fingers digging into the doughy flesh of her body and feeling it up in response! "Issei...! You...! I know what this is now...aaghghhhh...! Ooohhhh..! This isn't an affliction at all. You're in...some kind of specialized state of heat...!"

Issei was now feeling his cock bulging noticeably through his trousers as if he'd grown a third leg between Rias's thighs. His body started to obey his instincts as he brought up each of his hands to the top of her shoulders, sliding down the straps of Rias's lingerie till the cups of the girl's lavish red-lace brasserie spilled off her gigantic breasts. Those lush, bulbous E-cup-sized breasts just spilled freely out into the open and bobbled gently with the girl's nipples quickly becoming erect thanks to his Pheromone field. Seeing that happen before his eyes as well as watching the growing look of sexual distress come across his girlfriend's face furthered Issei's state of lust as he lunged right at one of her tits with his lips held open. His lips part and latch onto the girl's right tit with her nipple being gingerly swallowed up from inside while his teeth gently nibble on that rosy nub of soft pink flesh, leaving his left hand to grab onto Rias's other breast and begin feverishly groping it with precise movements of his fingers. He was exploiting the hidden erogenous zones of Rias's breast by expertly prodding every sensitive spot to where she was now screaming into her left fist in utter bliss.

"Hrraaggghghhhhh! Schluuuup....sllrpp..shluurppp...sllrppp..mnghgmm..! Rias...! Your breasts....oohhh...I love them so much...! Mnghmmm....sllrpp..shlurppp....sllrp..sllrppp..shlruppp mnmmnh! Opppaaaiiii..!" Issei growled into the girl's chest in that instant as he started sucking gingerly on her right nipple, letting it dab between his tongue and his teeth while slowly twisting the other one between his fingers in ways that left Rias reeling from the insanely strong wave of pleasure that followed such savage foreplay. She was now buckling in her posture and feeling preyed upon by Issei's animal instinct, only now realizing that it was indeed a genetic trait of all male Red Dragon Emperors to have when reaching a peek of 'Heat' following sexual maturity.

Issei now wanted to breed Rias Gremory and his Red Dragon body was compelling him to take her in any and every way possible to make it happen, starting with this.

"Aaaaaaagghghhhhhh! Ooohhhhh! Issei-Kuuuun! Aaaaaahhh! Y-you're usually much more gentle when it comes to foreplay...b-but this feels...ooaaahahhhh...divine as well! Better even..! Mmnhmnhh....ohhhh...Satan, you're just an animal right now...! Don't stop though...! Play with me in any way you like...Issei! I'm all yours....aaahhhhh..haaaa...!~" Rias cried out in ecstasy, feeling her boyfriend's lips hungrily suckle on her breast a little stronger as he guided her over to lie back onto the bed while getting on top of her body. His bulge, as nearly as large as a bulky fist due to it being constrained inside of his pants, was pushing out and prodding Rias's flat stomach as he had straddled her sides with hands busying themselves with her tits. He was fondling the other masterfully by either squeezing the enormity of her breast in his left palm or by tweezing her sensitive nipple, stimulating Rias in ways she'd never felt before as everything she felt was amplified through their touch at this moment. 

Little did either of them know or even care, the door was left open and the noises Rias making while Rias devoured her right nipple with his mouth, could be heard by a certain pair of Nekomata cat ears making their way closer to the source. They belonged to a certain, petite, young girl who was part of the Gremory Peerage and effectively a member of the 'Family' that the Princess of Ruin made. She had silvery white hair, a pair of tufted feline ears with white fur sticking out of that bob-cut mop of hair, and possessed a pair of feline-like golden eyes that she was now rubbing as she walked down the hallway to the source. Her name was Koneko Toujou and she was stirred from sleep when hearing a loudly whimpering Issei call for help quietly when walking past her room just as she was about to go to sleep.

"Oohhh...that noise, it's...coming out of there now, but that's...Lady Rias's bedroom, isn't it? Could Issei-Kun be....nghh...coming to her for the usual 'stuff' they do together or is it something else? It sounded like he was in pain when I heard him earlier..." Koneko said as she waddled down the hallway, hearing a series of moans and growls grow even louder the closer she got. She was wearing a simple, elegant, yet seductive lingerie sleepwear as well with its transparent design showing off the lithe curves of her petite body. It was colored white, as befitting of Koneko's sense of purity and innocence yet she had put this on earlier in hopes of attracting Issei when she woke up in the morning. 

Her eyes bolted open when the noises got louder and tufted feline ears perked up as a blush now colored her face. Koneko realized that the door was left open when she arrived in front of it, staying out of sight and letting her curiosity get the best of her as she saw Issei ferally tugging on both of Rias's large breasts with his hands and squeezing them strongly while taking turns chewing on each nipple in tandem.

'Oh....my...God...! Nnghmhh! Issei-Kun....! He's...just outright savage right here...! Is he...always like this with her? Maybe Rias should do something to control him because this looks rather intense and he appears rather different right now, almost like he's gone savage....' Koneko thought as she stayed glued to the spot she was standing in, keeping herself hidden behind the door with her yellow eyes peering in at the sight of Issei strongly gnawing on Rias's left tit.

"Mngghmmmhh...! Hmnghmm....Sllrpp..shlurpppp..sllrpp...shlurppppp! Amghhmm! Breasts..! Opppaaaiiii....! Rias..! Riaaaaasss...! I...must...breed.....nggghnhhh! Mnghm...Sllrupp..shlurpp..slruuppp..sllrrpppp...mmnbhm!~" Issei moaned between into her nipple as he let his tongue roll itself all over the areola, squeezing it fondly between his hand as he made sure to latch his hungry lips around the sensitive parts to where it made Rias croon loudly with her back arching upward from off the bed.

"Aaaahhhhhh..aaaahhhhh...haaahhhh..mnghmmm! Issei...! oohhh..! Issei...! ..mnhhmm..if you really need to.....breed me...then...take off my undergarments...and let me see your cock as it is now..! Mnghmmm!. Oohhh..you've gotten me so excited and pepped up, I've never felt this way before and you usually make me feel like melted putty in your hands already....! Aahhhh!~" Rias let out a euphoric moan, making Koneko blush strongly as she stayed rooted in her hiding spot to watch the rest of his affair go down while also feeling her inner thighs buckle inward with growing need. The petite Nekomata Reincarnated Devil was having a hot flash of her own as she watched Issei pull back from attacking Rias's massive breasts and begin tugging down the sides of her thin red-lace thong. The inner folds of her pussy started to swell with growing need and became increasingly sensitive to the point that moisture was escaping into the cloth of her white-lace panties.

Koneko even hunched a little in posture as she clutched the side of the door, eyes focused on the sight of Issei taking off Rias's lacy red thong from over each of her legs. Her nether region was completely exposed and showing him the tantalizing sight of her pussy in all its eternal tightness and juicy pink glory as she willingly spread her legs before him in a wide 'V' by holding onto the back of her thighs with her hands. Rias was smiling seductively as she watched Issei, who was still breathing loudly with heavy grunts, pull open his trousers with a tug of his hands. 

'Am I going to see Issei-kun's....?!~' Koneko thought in wild excitement as the young man undid his belt buckle and unfasten his fly to let out a massive bulge protruding from inside of his boxers before shrugging his jacket down from his shoulders. With a small push and tug of his fingers, the bestial Issei let out his throbbing thirteen-and-a-half-inch erection.

!

Koneko had to cover her mouth with her right hand to keep herself from being found out when she nearly squealed a loud 'Nya' in response to seeing Issei's cock for the first time. Out swung a massive pair of balls from underneath that made her insides lurch heavily with excitement even more, making the girl receptive to the Pheromone field now that she was in range and feeling the contagious fit of sexual heat herself. Rias, on the other hand, had a different reaction to seeing such a mammoth of manhood present itself from between her legs.

"Oh my Satan...! Issei...! You've...gotten bigger...! You were already large, but it seems you have grown with this...state of Dragonic Heat you've entered...!~" Rias pointed out and Issei, not feeling the need to exchange words due to the primal mood he was in, decided to grip open each of her legs when preparing to mount the girl in a full-on mating press arrangement. He got up on his kneecaps and pressed each of his legs down into both of Rias's thighs, pinning back her legs completely to where her feet were dangling in the air with her pussy completely vulnerable to a drop-down insertion from his cock now that the bulbous tip hovered above it readily.
