"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. 

Issei would've normally prepared just in case he'd hurt Rias when driving his cock inside of her body like before during their earlier romps behind Kuoh's doors, but he was currently far too manic with lust right now to care as he spread open the slick folds of her pussy with a hard shove of his waist. Rias clenched her teeth as she felt the difference immediately once her walls started sliding around the enormity of his length with Koneko watching closely from beyond the door.

"Hmnghghh! Rias...!~" He grunts as he feels the sliminess of her tight, vaginal walls start clinging tightly to his length once inch by inch his rod shoves itself thoroughly through to the back of her womb with the next push of his pelvis. A loud clap of skin echoed out as Rias felt Issei's waist and thighs collide into her lower half with her legs bent high over into the air with the full penetration in effect.

Spleeuucchhhh!

"Uuuuaaaaaaahhhhhhhhhh! Issei....! Mnghghm! Oohhh..Satan! I feel so much fuller than ever before..! Nngghhh! It's like you're reaching into me with a literal arm at this point! Mnnghnhm!~" Rias cried out in a mix of ecstasy and pain as she felt the insides of her pussy stretch in ways it never had before. Issei was already well-endowed before this unexpected transformation of his, but now he was as sizable as a literal bull and making sure each turgid inch of his thick cock was wedged deeply inside of her while he hunched his frame over her body. She gave herself entirely to him out of submission while bringing her hands up to latch onto the back of his neck, missing the awestruck expression on Koneko's face while she watched. She remained hidden even now, but the increasingly horny Nekomata girl was beginning to strongly stroke her folds through her lingerie more swiftly while biting down on her bottom lip with excitement. 'Soooo.. full..! Oooohhhhh..thank Satan for this gift, Issei..! I'm so glad you were the one to become the next and truest Red Dragon Emperor..! Aahhhhhh!~"

Issei was practically in a bestial state of mind right now as his base instincts compelled him to begin bucking downward into Rias's waist with his cock now drilling the very inside of her womb with much force. Koneko watched as he raised his hips high and slammed them back down onto the redhead's body, making her buttocks quake and quiver while a splotch of moisture came out of her sex. She nearly let out a loud, audible gasp of shock when seeing Issei's monstrous manhood stretch out her pussy and plunge voraciously into her opening with brutal force. He was fucking her like a beast and Rias, so far, was absolutely loving it as they began their latest sexual romp right here in her bedroom.

"Uunghghhh...! I'm going now..! Rias..! I want to breed you...! I want to have you all to myself from now on! I'm...moving now! Ooohh..your breasts...feels so soft and squishy and your pussy feels amazingly tight, more than normal...! Unuh..unh....unh..unh..unh..unh..unh..unh..unngh..mgnhhhh! Riass..!~" Issei howled in an almost bestial voice as he began raucously slamming his waist down upon Rias's body from above, making her legs waddle about in the air like a pair of trees being blown by strong gusts of wind.  Her pussy was reshaping itself as it enclose its walls around Issei's length, clutching it tightly and flexibly contracting around it in response to his incessant thrusts delivered into her womb. 

This sensation was driving Rias crazy with pleasure as her tits began to jostle about relentlessly to the rucking pelvis-to-pelvis motions of Issei's waist colliding into hers.

"Aaahhhhh! Issei..! Mnghh! Ooohhhh..Issei..! Aaahh..ahh...ahh...ahh...ahh..aahh..aahh....aahh..aaahh! Oohhhhh..my..! Mnghmmmm! Fuck me..! Absolutely devastate me from within, Issei..! I'm all yours..! Oooooaahhhh..!~" Rias cried out in ecstasy, practically rolling her tongue out of her mouth as the savage, incessant ruttings of the Red Dragon Emperor's cock kept pounding into her hole at a gradually accelerating rate. Despite his frenzied state of lust for Rias right now, Issei was still somewhat lucid and determined not to be too rough with her as he placed each of his hands down around the sides of her head when lowering himself even further.

The two of them relentlessly ground their navels together with Rias's buttocks quivering salaciously in front of Koneko's sparkling eyes. The slick and almost graphic violations of her pussy being tunneled out by Issei's massive dick was almost hypnotic to the girl, so much so that she began fingering her pussy after sliding a finger inside and begin stimulating her slippery vaginal depths to the show being performed before her. The curious Nekomata 'Pawn' of the Gremory Peerage hunched a bit and leaned even closer to the door, risking exposure as she started dipping her digit deeper into her pussy while watching Issei's cock move in and out.

"He's just...driving it all into her, so savagely...and so...wildly like an animal...mnghm! Why can't I bring myself to look away from this and go back to my bedroom...? Issei, you..sleazy and perverted jerk...you're doing this to me somehow, I know it..! Mnghmm! Uuahahh..aahhh...aahhh..aahhh...!~" Koneko huffed quietly to herself, trying to stifle her mouth from being too loud while she masturbated to the show. Her finger didn't want to leave her sex and her eyes never wanted to avert their gaze from the sight of Issei's cock plunging downward into Rias's pussy from above. 

It was as graphic and oddly intoxicating to watch for her as it was nature taking it's course. His cock just blurrily drove itself deeper into Rias's pussy non-stop, almost becoming loud enough in its penetrations for Koneko to hear the slippery squelching noises of coitus with her Cat ears. But thankfully, Rias's wailing moans of euphoria were drowning them out along with the echoey chorus of their bodies slapping voraciously together.

"Uunghh..ungh..ungh..unghh..ungh..uunngh..ungh..unghgh..unghghh! Rias..! Mnghmmm! Mh..mnh..mnh..mnh..nhh..mmmghghhh!~" Issei cried out in a bestial grunt, feeling the Red Dragon Pheromones in his body becoming stronger without fully realizing what he was doing. It permeated the area even more and made its way over to Koneko in the form of an invisible mist, one in which she whiffed rather strongly the moment she was close enough to notice it.

"Mmnghmmmmm! *What is..he doing to me..!? Mnghghh! Uuuhhh! I can't..control myself...much longer..! Ooohhh...damn you, pervert..!" Koneko whimpered quietly after stifling her lips with her other hand, beginning to feel every nerve inside of her petite light up with stimulation and sensitivity.

Meanwhile, back over with Issei and Rias, the former had leaned back just a bit so he could grab onto one of the girl's bouncing boobs and lean in from the side to begin kissing up her neck like some kind of romantic Paramour. He was still mate-pressing his hips down upon her writhing body, enjoying the sensation of her soft flesh clapping rigorously into his from below while Rias attempted to wrap her legs tightly around his hips from the sides.

"Aahhh..ahhh..ahh...ahh..aahh..aahh...aahh...Issei-Kunnn! Oooaahhh..yes..! Mnghhmm! Oohh...play with my tits as much as you like, my Emperor..! Mnghmm!  Uuhh..uuuh...uuh..uuhh..uuahh..ooohh..I think I'm cumming already, Issei..! Issei......!~" Rias cried out as the virulent undulations of his hips and the piston-powered thrusts he was delivering unto her sensitive pussy were beginning to become too much. She had lost count of the time and assumed he had been barely fifteen minutes since they got started, but Rias was already driven into a pleasure-addicted frenzy because of Issei now.

The tight sensation of her walls clutching his cock as it pummeled its tip directly into the back of her womb was pushing the girl ever closer to orgasm territory for that was where she had her G-spot. Issei often reached that special place time and again during their romps before, but this time he was claiming her in a more savage way that made Rias feel like she was melting. Her legs shot out into the air to quiver more nonsensically than before with her toes clutching tightly together during the onslaught of Issei's next several dozen thrusts. He kept on fondling her right between his hand and his fingers, clutching it fondly as he tweezed the girl's nipple while slamming even harder into her groin.

"Nnghh..nghghh..nghh..nghh..mgnghm..nghghh! You're tightening up..! Rias..! Mnghmm...! I'm....going to cum..! Breed you....! Make you bear my children..! Uuaagghhhh! Uunh..unh..unh...ungh...ungh..unugh..! Mnghhh! Riaaaassss.....!~" Issei howled, grinning lasciviously as he felt his cock pummeling into the depths of Rias's ever-tightening pussy with more force, feeling her slickened pink walls starting to tighten around it while unaware of Koneko's presence behind. But Issei's body, being enhanced by the Ddraig and the enhanced physiology of the Red Dragon Emperor meant that he could pick up her scent as she was becoming too engrossed in pleasuring herself to notice the odor of her arousal reaching his nostrils.

Fortunately for Koneko, for the moment, Issei was too engrossed in driving his dick as far up into Rias's pussy while keeping his hands planted down around the sides of her head onto the bedspread underneath her body. He had reluctantly let go of her breasts for the moment and drove his crotch fervently into Rias's groin, making her legs shoot out and straighten as he raucously bottomed out of her tightness with excessive force. Rias had tossed back her head and arched up her spine, making her breasts wriggle salaciously as she felt her orgasm about to hit her like a brick wall.

Coincidentally, Koneko was close too as she had dived both sets of fingers underneath her lace lingerie thong to dip as many into her waiting sex as possible when she started going off.

"Isseiiii..! I'ts here..! It's here..it's..heeeeere..aaaahhhhhhhhhh! I'm cumminnng!~" Rias cried out as her legs straightened out for the last time beyond the sides of Issei's hip-bones, feeling her insides twisting aggressively in orgasmic release around his cock as he slammed into her one more time before cumming.

"Ngh..nghgh..nnghgh....here....it comes..! Rias..! Umnghm!~" Issei delivered one last grunt of exertion as he shoved every inch of his immaculate cock deep inside of the Ruin Princess's pussy full-throttle, feeling the squeeze of her cervix beginning to coax sperm out from his balls while at the same time hearing a third party's wailing moan somewhere behind the door to the bedroom. "Ooaaaagghhgnghh! Uurghh!~"

Spplrrt..spplrrt..spplrrt..spplrrt..spplrrt..spllrrt..spllrrt..spplrrt..spllrrt..splrlrt!

He was delivering a thick peppering of highly virile, Red Dragon-enhanced sperm directly into Rias's fertile womb with the force of a high-powered hydrant. Every thick spurt of his cum sent Rias into a mid-coital frenzy that caused her toes to clench tightly together and make her body shudder explosively in one mind-blowing orgasm. So much of his cum was pouring into her depths and Rias was showing her reaction to such an enervating experience of having Issei breed her outright by rolling out her tongue and rolling her eyes north in obvious ecstasy. 

"Nnghm..mmghmm..mnghm....huh? Is that...? No way...?" Issei asked himself in mid-coitus while feeling his member spew thick ropes of sperm directly into Rias for the duration of a couple of minutes longer when he looked back to see the door to the bedroom ajar. And beyond it, was the petite Pawn Nekomata hunched over with both hands between her legs, reeking of sexual arousal. She was sweating hotly and leaking a bit of moistness from between her thighs where a discarded white-lace thong remained crumbled up between her feet.
