********
Rias Gremory’s Perspective-
*
“It had finally happened, the fated day that I had been dreading for so long up until this point had at long last come full circle; my arranged marriage to Riser Phenex. I was helpless to prevent it, Issei tried his best in the agreed-upon duel, but was yet defeated by Riser completely. He left with a saddened heartbroken look on his face, one that I would never forget for as long as I lived. When all was said and done the agreements had officially been made, everything was signed following the match and I was to be wed to this disgusting womanizing Riser Phenex becoming his political bride. In comparison, I was no different from his own peerage comprised of collected women who all act like his trophies and sexual toys. He treats every girl and woman there the same way as he does with everybody else and uses them with shameless indulgence all while wearing a smile on his face. I was in despair, nothing could get me out of this arrangement barring running away from it all completely and becoming a fugitive from Underworld Law. If I had done that then my entire family, the Gremory Clan would likely become punished in my place, or deposed of power so alas……I had to endure.”
“The Wedding happened with the two of us at the Altar within an Underworld chapel a week later, it was attended by many important members belonging to varying factions of the Old Devils. Among them was my older brother and current Maou; Sirzechs Gremory. I could tell he greatly disapproved of this arrangement and showed utter content for this outdated tradition I had been put into, he protested it rather openly despite it happening anyway under his rule anyway. I admired him even more for that. Old pacts and contracts between Devil clans can never be amended or annulled unless certain conditions were met, or at the very least until Riser Phenex loses interest in me, which I doubt would ever happen. We kissed on the Altar and we left the ceremony once the banquet was over with, thankfully he had too much to drink that day and passed out on the queen-sized bed we now shared. I was very thankful that this man had a low tolerance for Brimstone alcohol coming from the Underworld, he’d be far too insufferable otherwise. Even so, he was very callous, rude, and childishly petty in claiming me as his personal property in front of everybody, boasting about like it were a battle for supremacy.”
“I wanted out so very much, my heart was filled with regret the entire time I lived in the same space as him. Even knowing the risks and the consequences I secretly planned to run away from Riser and this sham marriage sometime later down the line. I’d gladly risk myself in becoming a rogue princess, a fugitive from Underworld Law if it meant not sharing my body with this sleazy vile monster. Thankfully, I no longer had to make that choice, at the very least I didn’t have to give Riser any kind of pleasure nor my innocence. Things changed for me ...in the most unexpected way and it started with a visit from my older brother Sirzechs Gremory.”
“He came to me...on the night of my supposed Honeymoon with a different aura about him, one that I found ...irresistible.”
End of Rias’s Perspective
*****
Opening the double-wide doors in stunned surprise Rias blinked twice in a stupor as she saw her magnanimous older brother, and current ruler of Hell, Sirzechs Gremory standing just outside wearing a confident smile on his handsome face.
“Evening, baby sister, surprised to see me?” He asked in a suave manner.
Rias simply nodded and stepped out of the bedroom into the hallway to talk to her brother in private. She noticed his eyes were drifting down her full-figured body, Sirzechs drank in the sight of his younger sister wearing a very revealing light red lace lingerie around her curvaceous body. Needless to say, he liked what he sees.
“What are you doing here, brother? Does….” Rias asked then trailed off as she quickly looked down the hallways noticing that the maids and other servants were sleeping soundly while leaning against the walls. It was the obvious work of a sleep spell and it made her look back to Sirzechs with an eyebrow perked in curiosity and confusion. “...does anyone know that you’re here? Why the secrecy in visiting me and my...ugh ...husband's home at night in the first place?” She asked using the word “Husband” in the most disgusting way possible when thinking about Riser.
Sirzechs said nothing at first, instead, he brought his right hand up to his sister’s soft face gently stroking the side of her left cheek. This was making her even more curious despite the thumping feeling of her heart inside her chest. Her eyes widened a bit in startled surprise, her brother was definitely giving off a certain vibe that was different from before and it mystified Rias completely, attracting her to him even more until he spoke up.
“Sister, I know you truly hate the situation you find yourself in. Trust me, I know. I wish I could undo it all myself, but unfortunately, it is an absolute fulfillment of the contract made ages ago before we took to power. That being said, I have an offer for you. One that only you can take and one you will certainly enjoy since it’ll mean betraying that unworthy swine Riser Phenex. Are you Interested? I do hope that you are.” He asked darkly with a charming smile and slight growl in his voice. Rias felt her hope returning bit by bit as she listened to her brother’s words hanging on to the feeling that they were giving her.
Slowly nodding her head she looked back down the spacious hallways hoping that none of Riser’s own peerage was around to be nearby and listening in. Thankfully her worries were alleviated right away.
“Worry not, I put them all to sleep and the spell I used will leave them with no memory of my presence here. There’ll be no trace of my existence to be found tonight, you forget that I am the current Maou after all. Also, It is quite unfortunate your husband has no taste or tolerance for the Underworld’s alcohol. I wonder who would have spiked it?”
At this feeling Rias felt even more alleviated to be in his presence and felt her hope skyrocketing making a smile form on her face.
“I'm ...I'm interested! Please, brother, tell me what I need to do. I’ll do anything.” She pleaded a bit desperately making her breasts jiggle from behind her lace-garment cups holding up her pendulous DD-cup sized breasts. Seeing them stirred the beast inside of Sirzechs, even more, making him feel very tempted to ravage her right here on the spot
“I will, but not here or now. First, you must come to my estate in secret within two days’ time. I’ll be there, just show up and I shall help you find your salvation. I love you, my dear sweet sister.” Sirzechs concluded making Rias’s face lit up as he suddenly leaned his head in close to hers brushing his nose against her own before pulling back. He silently and swiftly made his way out of Riser’s mansion parting ways with Rias for the time being.
She watched him go, waving him goodbye and wondering just what sort of game her brother was playing here. It puzzled her because she always knew him to be direct, even with keeping secrets and holding himself in a mysterious way, but all this left her wondering constantly what kind of foil he had in store for Riser Phenez. All Rias could do was wait patiently and relish the feeling of warmth her brother put into her body just from his visit alone.
‘Alright, I’ll wait, even though I am incredibly miserable being Riser’s wife while waiting in the meantime. Still, my brother is certainly acting more...brazen and charming, I never thought I could see him that way until just now. I think I like it.~’ Rias thought to herself and noticed the maids and servants all around start waking up around the house, she quietly returned to the bedroom behind her in order to get some sleep and eagerly await the date in which she could rendezvous with Sirzechs.
**********
Two days later….
Now, here she was within his estate under the guise of meeting her brother to further discuss future details regarding their end of the alliance with the Phenex family, at least in Riser’s eyes. In a way it was not wrong nor suspicious for Rias and Sirzechs to be officially doing that together privately, it was the perfect guise. Rias would ‘Discuss’ things with the older brother, but not in the style that Riser would appreciate. No, not in the least. She walked into the illustrious estate of the Maou, was welcomed into the spacious bedroom of her older brother and his wife Grayfia by a random maid, and waited for Sirzechs patiently after hearing the doors close behind her. Rias shed off her traveling cloak revealing herself to be wearing her stylish and form-fitting school uniform instead of a normal dress at her brother’s request. She favored his request and enjoyed being in her school uniform again feeling it reminds her of her old School life at Kuo Academy.
It had only been barely two days since the marriage now and Riser and Rias hardly spoke to each other. This was largely due in part to Rias openly detesting him with every fiber of her being.
‘Hmph,it’s hardly a surprise that he barely cares to address any of my complaints at all despite us being married. I knew what to expect, but to serve merely as window dressing for his ego as a Trophy Wife infuriates me greatly.’ She thought to herself then sighed hoping her brother has the solution she was looking for. She sat herself down upon the edge of his large queen-sized bed thinking distantly about how different Sirzechs was acting when he visited her that night two days ago.
He had been oddly domineering and charismatic creating a sort of allure that drew Rias to him like a moth to flame. He was on her mind constantly lately and if she didn’t know any better she’d say he was flirting with her seriously. Rias didn’t necessarily mind it since Sirzechs had always been a charming benevolent man capable of capturing many hearts of the underworld, largely from girls such as her. Despite a Devil’s age being nearly limitless Rias was still a teenage girl at heart and rather flustered when thinking about her dashing Maou of an older brother.
Just then she was pulled out of her thoughts when the doors opened up revealing Sirzechs wearing one of his long dominion sleeping gowns over his adult-sized body. Her attention was immediately upon him as he entered giving a pleased smile on his face as he closed the doors behind him.
“Ah, Rias,I’m glad you could make it. I trust Riser suspects nothing about this meeting then?” Sirzechs asked making his way casually over to Rias as she sat up from the foot of the bed.
Nodding back to him with a playful chipper smile Rias gave him her answer as she admired from far away. The way the robe hung off of his chiseled masculine body, the majestic way he carried himself, the light in his green eyes that showed when he was staring her in the face subtly made her legs quiver as he walked right up to her.
“No trouble at all. So please tell me, brother, what is this solution you’ve mentioned to me? I cannot stand another moment alone with Riser Phenex, honestly every day I become closer to simply strangling him in his sleep right after poisoning his rejuvenation powers so that he doesn’t properly heal for a very long time.” She admitted making Sirzechs chuckle as he sat right down with his sister at the foot of the bed.
“He hehehe, I figured that would be the case. Well, do not worry…..your big brother is here to help you.” He added with a dark purr sending chills up Ria’s spine. He then placed one of his hands around her right thigh making her blush slightly as she turned to look at him with a look of surprise on her face.
“Big Brother? What are you doing?” She asked despite feeling her chest fluttering.
She never knew this side of her brother in all her life, but she liked it more with each passing second. Sirzechs had an impassioned look on his face as he squeezed her thigh gently into his right hand, smirking he quickly shrugged off his gown completely after standing up. Rias’s face became stricken with surprise as she watched him become half-naked before her own, appearing bare chested with only the lower half of his robe still worn on his lower body. All his masculine features out in the open and Rias was finding herself hot and bothered just by seeing his chest naked before her startled eyes.
“Simple; I am solving your problem, as well as dealing a deep blow to Riser Phenex for stealing away my precious little sister. Tell me; your honeymoon didn’t quite happen now, did it?” He guessed and she shook his head immediately with a relieved sigh confirming his answer. This puts a smile on his face, Sirzechs crept closer to his sister’s face making her blush even brighter until he towered her young teenage body. “Good, it pains me to think of that man even laying so much as a finger on you, let alone taking your virginity away. I’ll be doing that instead.”
‘W-what?’ Rias thought silently to herself wondering if her brother was really serious about what he said. His left hand crept over her right clutching it gently with his fingers interlocking with her own until he pulled it up below her face affectionately.
“Rias, I will do that for you and offer the comfort you so desperately need and deserve right now.” He revealed with a serious look in his eyes when staring into his sister’s surprised face.
“S-S-Sirzechs? Big Brother? This ...is a prank, right? I mean, I truly do yearn for comfort and solace considering this arranged marriage of mine, but ...do you really desire me that way? Your own sister?” Rias asked as though wanting to confirm it first. Despite not having feelings for her sibling prior to this moment she always found him charming and perfect in the ways of being a man. Their earlier encounters magnified this feeling greatly, to the point her heart was racing even more right now. In Rias’s eyes, Sirzechs was both compassionate and fair, yet at the same time incredibly fierce and charming.
“Yes, I am serious. I cannot stand to see you so miserable by being with him, and I know for a fact that you are not the only one. I’m going to take your virginity before he does and then ...” Het trailed off and leaned in closely to her face remaining a few inches from it as her cheeks lit up becoming as red as her hair. “.... leave you with a baby of my own seed, of our own blood before taking his peerage away the same exact way, one by one from him entirely. Riser will have nothing left, befitting of a man who sleazes around making a mockery of devils and doing nothing to deserve his nobility besides than being of the Phenex clan.”
Rias felt like her soul was just ripped out of her body when he finished, her heart was racing after hearing this information and realizing her brother was in-fact one hundred percent genuine about his plan. Sirzechs Gremory was going to take his sister’s virginity and leave her with a child before repeating the process with the rest of Riser’s female peerage. The only thought on her mind was that if he should take her like this, then it’ll be in the ways of love and not just lust. The best-case scenario would be Riser divorcing the girl should it come to pass. Thankfully Sirzechs answered that unspoken question for Rias before she could speak it.
“I know what you’re thinking and the answer is ‘yes’ to all of them. Yes, I am serious and am not playing with your feelings of despair. Yes, I intend to take you in when or if he leaves you after finding out that it is not his baby that’ll grow inside of your womb. I truly love you, Rias Gremory, I adore you, and I will make you mine right here and now physically under Riser’s very nose. Have anything else to say to that?” He asked and Rias felt her throat dry off cutting off her ability to speak.
She was shocked and surprised at hearing this, yet her heart was racing telling her that she yearned for it to really happen. So she shook her head at his request and brought up her hands welcoming her brother into her soft warm arms for an embrace. He accepted it by placing his hands around Rias’s wide waist and feeling her hands around his neck lovingly with a flustered look on her face.
“I just have two things to say actually; be gentle.” She purred feeling her resolve crumble to his advances. Sirzechs smiled before wrapping his right arm around her waist entirely then pulling her onto his lap. Their lips met swiftly in an intimate and hungry open-mouthed kiss wrought with incestuous passion. The instant Rias felt her brother’s warm lips on her own sent sparks throughout her entire system, suddenly she was pulling his mouth further onto hers letting their mutual passion for each other come out.
“Mmmhmmm!~” Rias purred excitedly into her brother’s lips letting out all her pent-up stress and sexual frustration unto them while feeling his hands roam down her body cupping her butt. She felt him squeeze her ass fondly through her school uniform skirt causing the girl to squeal quietly into his face, they hungrily swapped spit with tongues rolling about erotically in a languid back and forth motion.
She moaned and panted happily while feeling her brother keep her around his strong body with a thickened bulge rising up underneath her buttocks. She looked back to her bottom real quick and saw that he was indeed hard, and quite large on top of it all. This sent a wave of excitement through her and made her feel insanely horny right at this very second, incest or not, she’ll be damned if she has to live out the rest of her days as Riser’s unhappy and miserable wife. She’ll take any risk and accept any chance possible including resolving her adoration for her older brother with this union.
“Hhhmmhm.~” Sirzechs moaned into Ria’s mouth until she slowly pulled off leaving a trail of saliva bridging between their lips as they stared into each other’s eyes with an unspoken passion. “You taste like strawberries, heh.~ How about we loosen that clothing of yours and take everything off, Rias. I was already pent-up by the time you arrived here and had been patiently waiting for this very moment for some time.”
‘He has? My brother...had these feelings for me for this long?’ She recounted feeling a warmth flow through her chest as she nodded at his request. Taking a step back from him and dismounting herself from his lap Rias began slowly undressing before like some common showgirl.
In her lust-addled mind, she failed to ask what Grayfia, his wife, thought about this arrangement, but assumed that maybe everything was in secret and kept from her and their child. Part of her would feel bad if she was helping him cheat on their vows while breaking her own, but another part of her didn’t care. She wanted this, needed it so badly right now. Seductively pulling off the top layer of her intricately designed uniform outfit Rias eventually shed everything until she was left in nothing but lacy pink lingerie set complete with a brasserie and a thong.
Sirzechs sat back on his bed marveling at his sister’s voluptuous young figure ripe with feminine beauty in all it’s curvy perfection. Rias had a beautiful hourglass shape, a thick pair of E-cup sized tits with a slim waist, and wide pair of baby-bearing hips, which in his eyes were perfect for what he had in store for her. She blushed like a maiden at becoming half-naked before her own brother and hastily reached back behind her body to undo the latch of her bra. Letting it fall to the floor Rias exposed her breasts fully with pink perfect nipples erect making his mouth water.
“Fu fu fu, like what you see, Big Brother?” Rias teased while raising her arms above her head pushing out her chest in a provocative manner. Her breasts were nearly as big as Grayfia’s and just as supple with plenty of youthfulness seen in her skin. Rias was a healthy size DD and waved them around casually in slow gyrating motions. Sirzechs nodded eagerly as she strutted around with hips swaying performing a slow strip dance for him, Rias twirled around making her supple ass shake before she started moving in an exotic manner.
For some reason, this became instinctual for her making it all the more wild she was doing it for her own magnanimous sibling. Rias shook her hips side to side causing her buttocks to jiggle voraciously in the style they call ‘Twerking’, Sirzechs was certainly mesmerized by it and feeling his erection stiffen to insane levels as he watched his sexy cute sister perform her erotic dance before his eyes. She turned around swiftly making her large breasts sway even more as she began jiggling them around in circles for his amusement like a common belly dancer. The man had a slight trickle of drool coming down from the corner of his face, he watched in perverse entertainment and started undoing the lower parts of his robe ready to expose his darling sister to his manhood.
Once she stopped dancing and turned around again, Rias looked over her right shoulder at Sirzechs wearing a coy smile on her face. Her hands gently reached down her voluptuous body to the hem of her thong’s waistband, hooking her thumbs around it she started pulling it down her wide hips down her supple ass and along her silky legs. Rias was gradually becoming naked before her brother’s eyes, keeping her socks on as she slid her thong down her creamy thighs and down to her feet. They reached her ankles and she stepped out of them entirely before being tossing them away to the side. She now stood completely naked with her backside facing him until she slowly turned around with hands moving to behind her neck making sure her breasts were fully exposed.
“Yes, I very much like what I see. You are very beautiful, sister. Now, my turn…..” He got up from the large spacious Queen-sized bed and with a flick of fingers made the lower half of his robe magically slide off of his body slowly stripping him fully naked from the waist down.
Rias’s eyes flickered with excitement as they roamed down to see his lower region , the lack of his lower undergarments was now exposing his thick thirteen-inch sized member standing at full mast. Rias’s mouth dropped open wide in surprise as she saw the biggest length she only believed belonged to actual dragons like Tannin. Her brother’s cock was as about as large as a miniature arm with several inches in thickness in diameter, complete with a thick pair of large bloated balls underneath his shaft. She herself felt a bit of drool leave her lips as the feeling of incestuous thirst started to swell up inside her body the longer she looked at it.
Likewise, Sirzechs enjoyed the sight of his sister’s pussy on full display in front of him, she had a faint fuzz of blazing red hair above her snatch looking as neatly trimmed as he would expect from a woman of dignity like Rias. he could also tell that she was very wet underneath, the ooze of her cum moistened her vaginal lips as they stood a mere two feet apart from each other. It was something that he was now about to correct.
Walking up to Rias he grabbed his hands around her waist pulling her closer to him and letting his erection prod her navel lightly while she remained up close and personal with her own brother. She looked up into his eyes blushing faintly around her cheeks until she brought her hands up to lock around his neck pulling herself closer to his large masculine frame feeling ready to submit everything to him. Sirzechs smiled at this and grabbed the back of her waist pulling her close until his face was mere centimeters from her lips. Rias could feel her heart pounding a mile a minute at the proximity until he spoke.
“I’m going to enjoy making you a woman, Rias. Then I can’t wait to reveal the big surprise I have waiting for you, but first let us enjoy this moment alone together and give you a baby.” He said soothingly into the side of her neck before pulling his sister back onto his lips for the second time letting their mouths collide in a wet organic frenzy of swallowing each other’s lips.
Rias closed her eyes and moaned passionately into her brother’s face feeling her tits pushed up into his chest smothering her nipples while picking up one of her legs to curl around his side. She felt his member push out between her thigh gap gently rubbing along the surface of her glistening pussy while feeling him gently saw it out from between her legs. The siblings kept each other’s hands wrapped firmly around one another in the embrace, Rias swallowed and suckled hard on his tongue while feeling one of his hands slide down to her ass cupping it then squeezing her cheek.
“Hnngghhh!~” She mewled loudly and tilted back her head a bit allowing Sirzechs to regain dominance by dipping her in his arms, her breasts popped out from above his face and jiggled gently as he steered her away to be placed on top of the bed behind them laying her down.
With a gentle thud, Rias landed gently on her back and propped her body up on her elbows watching with gleeful excitement as her brother crawled onto the surface prowling towards her in a predatory way. She bit down on her bottom lip feeling her insides throb with heated arousal, he got up close and personal with her voluptuous body next. Sirzechs slid one of his fingers down between her smooth creamy legs letting two of them slide gently against her folds. Rias immediately shuddered as she felt the strong digits of her brother’s right-hand dive swiftly into her glistening sex.
“Aaaaghh!~ Uughh……!” She cried out and arched her back pushing her tits up into his face as he started dipping them in and out of her sopping tight teenage pussy in a gingerly fashion. Quiet squelching noises started to arose from the aided masturbation and Rias found herself breathing loudly in large ragged gasps of pure ecstasy for he was hitting her most sensitive spaces with each and every thrust.
“Hhaahh…..ahhh…..nghhhh, Big Brother…..!” She breathed out until he dipped his head down into her chest capturing one of the heaving tits between his lips and squeezing her right nipple gently into his mouth. Sirzechs sucked his lips tightly around his sister’s areola making her tits pull gently into his mouth as though he were feeding on it like an infant.
This myriad of sensations started to drive her insane with pleasure and this was just foreplay at the lowest level. It only seemed to Sirzechs that Rias had not been properly pleasured at all before coming here, he smiled at that revelation and started sucking harder on her right tit.
*Shup..chup….schup...schupp!*
He sucked her tit faster and fingered her drooling snatch harder making her buck her body up against his waist as she frenziedly ground herself underneath him. One of her legs came up around his thighs keeping him locked in while he continued to finger her pussy and feed off one of her large bountiful titties. Rias had to bite down hard on one of her knuckles to keep herself from howling loudly inside of her brother’s house, though she was fairly sure the room was magically soundproof from within. Still, she mewled and whimpered pathetically behind her knuckle feeling her brother suckle her tit even faster until he slowly pulled himself off of her nipple with a wet pop of saliva before moving on to the other one. Wrapping his lips around his sister’s other breast Sirzechs started feeding off of that nipple now making Rias thrash her head around like crazy with growing ecstasy. Eventually, she could no longer hold it in and wound up screaming her lungs out in a euphoric frenzy.
“Hhhhhhh ...aaaahhhh!Big Brother!~” She cried out with eyes closing tight and her body twitching with orgasm making her juicy folds gush all over his fingers as she came in a hard rush.
‘Hmmm, she’s a squirter.’ Sirzechs noted when feeling her pussy squeeze tight around his fingers squelching all over them in a myriad of pussy juices until she finished thrashing about in climax.
Sirzechs felt her pussy gush a few more times with her insides clamping tightly around both his middle finger and index finger respectively until Rias eventually came down from her orgasmic high. Her chest was heaving making her breasts sway up and down as she feels her cum oozing out of her pussy onto her brother’s fingers.
Sirzechs drew them back out of her sopping cunt and brought the cum-coated fingers up to his face making sure Rias was looking when he sucked them into his mouth tasting her nectar. She blushed furiously hard at seeing her older sibling lap up the cum she just gushed all over his hand, the way he suckled each finger into his mouth cleaning it off in such a lewd way got her excited all over again. He didn't swallow anything down yet, instead, he lowered his face onto her own pulling her soft lips into a steamy kiss that made Rias taste her own cum as he fed it into her mouth. Together the siblings started meshing tongues languidly against each other exchanging the cum that gushed out of Rias’s pussy, it was such a debaucherous shameless thing they were doing, yet all the same she was very excited to be doing.
“Mmmhmmm. Mmuuaahh….there, nothing like sharing the tangy taste of one’s own flower. Hope you enjoyed that, dear sister, because I’m about to go to the next step.” Sirzechs said as he got up on his knees pulling himself up off of her body. He grabbed both of Rias’s legs and started spreading them apart to allow him full access to her youthful soft-looking pussy.
“*Huff...huff...huff*...Big Brother, are you ...?” Rias breathed out as she looked at her brother’s domineering form with a soft smile on her face. She watched him pick up one of her legs and lift it up over his right shoulder grabbing his member so he could guide it over to her aching pussy.
“Yes, I am, get ready to become a lady, Rias. I’ll treat you infinitely better than any man ever could. I’ll leave you with a baby, one that is not his, and perhaps one of many to come. I happen to have a certain fetish I’d like to tell you more about later, right now though….it is time to breed.” He said in a dark crisp voice just before pushing the head of his massive length directly into the spongy folds of his sister’s pussy. Rias instantly tossed her head backward pressing herself into a random pillow as she felt her folds spread wide to welcome her brother's dick.
A soft squelching sound came out with a slight gush of nectar spritzing onto Sirzechs navel. The tall redheaded man let out a blissful groan as he felt Rias’s tight sopping folds squeeze gently around the head of his dick. He watched her toss her head about with lips pursing tightly, her fingers and toes were curling up as she wound up wrapping her other leg around the side of his waist. Sirzechs growled in pleasure at feeling such a tight youthful pussy wrapping nicely around his dick, he pivoted his pelvis properly preparing to take his sister in a bent missionary position, leaning over her heavy voluptuous body while slowly sinking his dick into her even more.
With a quiet squelch of moisture, he shoved his gargantuan dick halfway into her cunt making her bite down on her right fist again while her tits started heaving excitedly. Rias shut her eyes tight and felt the large head of his cock pushing into the membrane of her virginity preparing to pierce and claim her once and for all. Sirzechs halted his advance reached down to pry apart her hands from her face holding them in his own with fingers interlocking intimately. Rias opened up her eyes and stared into her brother’s green gems feeling her heartbeat explode with excitement and joy as she felt warm love within their embrace.
“I….*huff...huff*....want it, Big Brother! Please…..!” *Wraps her legs tightly around his waist above his thighs* “....make me feel everything!” She hollered out with hands latching behind the back of his Sirzechs’s neck as he plunged his waist down upon her pussy sheathing every thick inch inside of her in one go!
Rias’s body tensed up with pain and ecstasy as she felt her brother’s dick pushing past her hymen, piercing it, and reaching the opening of her cervix prodding the entryway of her womb. Her legs shuddered and her chest jiggled voraciously as she felt a myriad of painful yet pleasurable sensations wrack her very core. Tossing back her head and yelling loudly in climax she wound up cumming tightly around her brother’s dick making him grunt with a smile on his face as he felt her insides churning around it in a tight convulsing fashion.
“Uuuggghhh…! Aaaaghh….! Aaa!~” She cried out in ecstasy feeling her body shudder in spasm again and again while feeling his dick sink in deeper till his balls reached her buttocks. Sirzechs waited for her to ride out her orgasm, her body shivered several more times with her insides squelching around his member some more until she was done.
Rias let out a sigh of relief leaving her chest heaving slightly until she felt her brother begin moving in and out of her in a gentle fashion. His long thick cock plunged inside of her depths reshaping her pussy muscles to fit only his length from now on.
“Nghhhh!......haahh…..!~” She cried out leisurely with a hard blush creeping up on her face as her body began moving gently to her brother’s movements.
“Mmhmm, you feel amazing, sister. Seeing how tight you feel tells me you’re enjoying this very much. I’m glad that fool Riser didn’t get to deflower you before I did, now lay back and enjoy.~” He breathed out and began bottoming out of her pussy with newly intensified rutting.
Together the redheads meshed their bodies together with Rias feeling her brother heave into her waist tenderly in intense vigor. Slap upon slap of flesh echoed throughout the bedroom with Sirzechs enjoying every second of feeling his sister’s pussy squeeze his meat tightly while it bottomed into her. His balls slapped into the cleft of her ass making them jiggle as he gradually started thrusting into her even faster. Now Rias was clutching the sheets of the bed feeling her pussy churning with every hard thrust of her brother’s cock embedding itself deeply into her sopping pussy. He had hit a rather sensitive G-spot inside of her cervix making her jolt spastically before letting out another ear-piercing scream of unbridled ecstasy.
“Aaaagggghhhh!~ Hhaaahhh…..mmmh ...mmhm...mmmh! Big Brotheeerrrr! Hhgnnhh!~” She cried out in mind-numbing pleasure as the bed began creaking loudly to their raucous lovemaking.
‘Nngghh…..! S-so good! I haven’t felt this amazing since taking my favorite blonde earlier this morning, she’s supposed to here any minute now though and will probably sneak into the bedroom while I’m busy with Rias.’ Sirzechs thought to himself as he felt the tug of Rias’s folds milking his member gently as he bottomed out of her.
Soon his pelvis was colliding frantically into her waist from above, Sirzechs was rhythmically slamming into his sister making her mewl loudly with every push his weight carried onto her person. Eventually, this leads him to him prop both kneecaps around her creamy soft thighs keeping their position steady as they fucked laboriously in frenzied lust. Their pace intensified with Rias letting her legs dangle over the top of his shoulders jiggling helplessly as she was being fucked hard. Her body meshed together with Sirzechs feeling his waist clap tirelessly into her frame making her tits jiggle voraciously while feeling the rush of pleasure coursing through her body at this very moment. Skin slapped together with breasts and legs jiggling about, Rias whirled her head around slowly moaning in pleasure while her brother fucked her raw. There was a gentle ferocity in his movements, a warmth his cock provided her that made her feel utterly amazing.
Sirzechs was grunting hotly with pleasure feeling his sister’s soft body rut passionately against his as he bottomed out of her for nearly half an hour when switching positions. With a low growl, he pulled her up onto his lap letting the full-figured girl bounce and writhe energetically onto his waist. The smacking sounds of bodily flesh reverberated throughout the room while Rias held her hands tightly around her brother’s neck gasping hotly with pleasure. Her legs locked tightly around his back keeping herself locked onto his dick, feeling his waist rut rhythmically into her body with ever-growing passion.
“Nngh..nghh...nghh...aagghhhhh! Hhoooooooh!~” She cried out again leaning her head back and letting her tits bounce up into her brother’s face as she felt her insides squeezing tightly around his dick even more.
After minutes of nonstop riding and bouncing with Rias rolling her hips along her brother’s waist both siblings were beginning to feel their bodies about to erupt with orgasm. The girl’s body writhed about bouncing frantically on the man’s pelvis feeling him jam his length in deep into her quim making her shiver with pleasure even more. Her cheeks clapped and smacked enthusiastically along his waist meshing into his skin as they both became sweaty in each other’s arms. Rias had hers tightly wound up around his neck embracing him fully with her lips hungrily sucking out his breath in yet another incestuous kiss. Sirzechs held one arm around his sister’s body feeling it press into his with tits sloshing around on his chest while they swallowed each other’s spit in such a languid display of kissing. Tongues writhed about wrapping around each other with Sirzechs gaining dominance over the younger Gremory Devil, they continued this exchange for what felt like minutes with Rias feeling her pelvis slamming down harshly upon his waist preparing to succumb to climax on her own. No doubt Sirzechs was feeling his length throbbing with growing arousal telling her that he was ready to cum inside of her the moment she hit the proverbial wall of climax.
“Uh...uh..uh..uh..uh...aaaggghhh! I'm ...I'm ...I'm cumming!~” Rias cried out bringing her head back with her chest pushing into her brother’s face as came!
With one hard slam of her pelvis meshing with his hips, she felt her pussy squeeze tightly around her brother’s length with every ounce of strength her orgasm had brought her. Rias ground herself into him extensively gyrating her pelvis around on throbbing cock until she felt it pulsate like a blood-pumping organ inside of her sex. She saw her brother howl like a beast and surrender himself to climax grabbing Rias’s hips tight into his hands then thrusting into her pussy with very hard automatic thrusts making their bodies join together in harmonious orgasmic ecstasy.
“Hghnnnhhh!~ Here it comes, sister! Accept my seed and bear my child!~” He shouted and felt his cock explode inside of the girl’s fertile teenage womb! His cock pushed all the way inside when it throbbed and erupted in a thick splurge of seed painting Rias’s insides white.
Upon feeling the molten cum of her lord and sibling Rias shuddered in ecstasy at the feeling it provided, just knowing that he was impregnating her was enough to set her off, but that knowledge combined with the sensation of feeling his sperm pour into her made it even better. Rias thrashed about along his muscular frame rolling her hips along his pelvis for the duration their orgasms lasted. She could feel every thick spurt of cum caking the insides of her womb and filling up her fallopian tubes to the point her uterus made contact with his seed. She had no doubt in her mind that after today she’ll wind up pregnant with the taboo love child of Sirzechs; current lord of Hell and her dashing manly older brother.
*Throb…..throb….throb!*
“Mmnnnghh…….! Ahh.~” Sirzechs sighed in relief as he felt the cum drain from his balls into his sister’s fertile young body. Once he was done cumming inside of her Rias went slack in his arms and fell back onto the bed. She was heaving exasperatedly with a blissful ahegao smile on her lovely young face, she watched as her brother leaned back on his kneecaps pulling his member out of her sopping snatch leaving it gaping and with a sickening splotch of seed gushing out of it. To her surprise, and great delight, she saw that Sirzechs was as hard as a rock again and smiling readily at her from above.
‘Incredible! But then again, he is the Maou...and my dashing older brother. Eat your heart out, Riser, I have found a true man.~’ She thought to herself wryly still catching her breath when the doors of the bedroom opened up startling her into a panic. On instinct, she scooted back into the edge of the headboard in surprise while sperm continued to ooze out of her gaping pussy, to her surprise her brother didn’t seem bothered by their new arrival and in fact waved her in.
“Come on in, M’lady. You’re right on time to join the festivities.~” Sirzechs said making Rias look to him in surprise as the doors opened up completely revealing a stunningly beautiful blonde woman with elegant semi-curled hair dripping down the side of her chest in an ornate ladies braid.
She was a grown adult with dazzling blue eyes, a dreamy smile, and dressed as though she were a high-class person from one of the more elite Demon Pillars. Rias was reminded of her own mother Venelana Gremory, but was also reminded of Riser’s younger sister Ravel when looking at the woman. She was wearing a long elegant gown over her voluptuous body, one that spoke of High Class and refinement. She looked at Rias with an intrigued smile as she closed the doors behind her making her way over to the foot of the bed as though she was summoned.
“You have gotten to bedding your sister already without me? Shame on you, Lord Maou, I was hoping to help you break her in.~” She mused with a soft giggle as she arrived at the edge of the bed keeping her hands in front of her dress waiting for him to say something.
Rias turned her face over to the side looking at her sibling with a questioning gaze until he spoke.
“I do owe you an apology, Rias, and an explanation. You see…..” He got up and went over to the side of the woman running his hands along her shoulders sensually before bringing them down to cup her breasts. The woman shuddered with a red tint on her cheeks as she felt Sirzechs fondle her rather large supposedly E-cup sized tits through her corset. “.....Lady Phenex here is my other Mistress, and rather another woman I am cucking that fool Riser with. She is his mother and her daughter, Ravel Phenex, is my illegitimate child whom you have already had the pleasure of meeting.” He revealed making Rias sit up in the bed wearing a look of utter surprise on her face.
‘R-Ravel is his child?! He’s started having children with other people before seducing me?’ She pondered feeling slightly offended yet at the same time savored that her older sibling was already getting one over on Riser by fucking his mom. Still, it was a sock to her system knowing that he already sired illegitimate children with other women behind Grayfia’s back. Rias looked at him hoping for an explanation, and to no surprise, Sirzechs was happy to give it.
“Remember when I mentioned I had a certain fetish I cannot get enough of?” He led on and she nodded, making his smile go wide as he peeled down the cups of the woman’s corset segment of her dress. Out came her large fluffy boobs jiggling slightly until he grabbed hold of both making the woman moan quietly in rising pleasure. “Well, it’s cuckolding, I happen to be fanatical about it, Rias. While it may seem undignified and rather debaucherous, it’s what I like to do and have done to me later down the line by my own children with their mothers, no matter who they be.”
He winked at Rias enjoying the sight of her surprised face as he continued groping Lady Phenex’s melons around in spirals causing the woman no end pleasure as she bit down on her bottom lip.
“Mmnnghhhh!~ Ooohh, darling! Please do to me what you already have done to your own sister; Breed me. Again! This time I hope you’ll bless me with a son, one that’ll grow up and fuck as per your insane plans and rather enticing fetish.~” She added making a sultry smile as she felt Sirzechs fondle her tits some more, squeezing them leisurely between his fingers. Rias watched with hypnotic fascination as he made her breasts swivel and squish together languidly in a very impassioned groping session, it was making her insides stir up as well when she heard Sirzechs speak out to her from behind the woman’s swan-like neck.
“Rias, you’ll work with me in granting Lady Phenex’s wish,yes? After all, what’s better than two members of the Gremory family subjugating and ‘Taming’ a high ranking Matriarch of the Phenex one? You heard her, she says she wants another child, one that’ll grow to fuck her making me a cuckold in turn.” He explained and this only puzzled Rias and Sirzechs brought Lady Phenex over to the foot of the bed making her dress shred into tears once it hit her back gently with a magical swirl of energy causing her clothing to rip.
“Gyyaaagh!~” She squealed out in pleasure as she was forced onto the bed placing her face and body in front of Rias’s legs, her ass remained stuck out bent over the side while Sirzechs got in behind her grabbing his cock readily for another breeding session.
“I...just have trouble understanding this unique fetish of yours, Big Brother. You wish for one of your illegitimate children to steal the women you impregnate out from under you?” She wondered while feeling an odd sense of perverse arousal coming from the thought of it.
Sirzechs merely smiled confidently and nodded while grabbing both of Lady Phenex’s buns then spreading them apart along with her legs making her pussy become fully exposed to him. She was already as wet as can be with moisture seeping down her folds, Sirzechs licked his lips eagerly with excitement and guided the head of his length in making her insides spread out wrapping around his dick as he sunk into her.
“ahhh!~ Yes!~ I’ve missed this! Please breed me, darling!” Lady Phenez screamed out in pleasurable agony. She felt her buttocks pushing towards Sirzechs’s body, meshing the skin of her cheeks deeply into his waist and feeling his member pushing its familiar way into her cervix ready to fuck her in raw savage fashion.
Her body shuddered, her face bore an orgasmic ahegao smile on it with eyes rolling backward and mouth hanging open. Her breasts swayed into the bedspread surface making the blankets shift while Rias leaned over closely to Lady Phenex’s face ready to join in on the action. She was still flummoxed by how odd and rather extreme her brother’s fetish is; breeding someone out from under somebody else’s nose then having that child grow to do the same in turn with the mother. It was something she couldn't really fathom he’d get into, but she saw the appeal in it. It was sinfully seductive and very enticing with it’s taboo, she cradled her belly again hoping she was pregnant with his baby if only just to spite Riser and get out from under his arm in marriage.
“You have a rather unusual fetish, Big Brother, but…..I don't dislike it.~ Fu fu fu fu.~” She purred and reached over with her arms wrapping them around his neck while Rias glued her lips hungrily with Sirzechs yet again, straddling Lady Phenex’s naked backside while doing it. Their mouths met in a languid steamy embrace complete with tongues rolling out into each other so wetly.
“Mmnnghhn! Mmhmm, Rias….!~” Sirzechs moaned into his sister’s mouth tasting the inside of it with spiraling motions of his tongue. He loved the feeling of Rias mewling on contact when his tongue dominated her own with ease, meanwhile, the feeling of Lady Phenex’s pussy started clamping even tighter around his meat making his pelvis begin moving on their own into her buttocks.
Gentle slaps of flesh began echoing out and the blonde woman’s buttocks cleaved and squished into Sirzechs waist while feeling his dick churning her insides in an expert profound manner. Eventually, the slapping noises became more rampant and Lady Phenex was now bouncing back and forth on the owner’s crotch moaning into the bed while doing so. Her body heaved back and forth with Sirzechs expertly rolling his pelvis into her rear causing Rias to stumble a bit while he fucked her so eagerly.
“Mhmm...mhmm..mhmhm..mmhmm...mnnggghh! Aaaahhhhh aaahhhhh!~” She cried out and raised herself up on her hands causing Rias to stumble back off of her naked body as she took a Doggystyle position. The redheaded landed with a gentle thud onto the bed and fumed slightly until she started watching the blonde woman’s face pulling and pushing forward with mouth hanging agape breathing loudly with hot moans.
Sirzechs smiled at Rias then leaned forward grabbing the blonde mother’s tits and pulling her body back so that he could be fucking her while she stood up on her kneecaps. She was still leaning forward with her breasts jiggling voraciously in front of Rias’s face, only an elevated angle. He hooked his arms around from under her shoulders keeping her mounted on his dick while it plundered into her quivering pussy over and over again. The slapping noises of flesh colliding with flesh grew even louder. Her pussy squelched all over Sirzechs’s massive penis making it throb as he bottomed out of her with an ever-increasing pace.
Soon her buttocks were raised up off the surface rising a bit higher in the air showing Rias her buns slapping into her brother's waist as he savagely fucked her. He drew back his pelvis and delivered one hard thrust directly into her sex making his cock push directly into her cervix thereby entering her very womb! This sent jolts of pleasure throughout Lady Phenex’s body making her cum already around Sirzechs’s massive length.
“Haaaaagghhhhh!~” She howled loudly as her body quivered with climax making her body slam back into his waist more rampantly as she rode it out.
Rias, not wanting to be left out at all, went over to the blonde motherly woman and held her face in her hands, bringing it up to her own so that their lips could meet in a languid lesbian embrace. Sirzechs became harder than he was already at the sight of his sister making out with Lady Phenex, their lips curled into each other with tongues rolling out wetly between their mouths. They tasted each other with a boundless hunger while he was feeling the blonde’s pussy clamp tightly around his meat, even more, making him start rutting into her body again.
“Nghhhh! Oooh that’s it, indulge each other. It’s certainly doing wonders for me right now, both of you...nghhh...along with the female half of Riser’s peerage are going to become a part of my growing dynasty of bastard children.” He voiced darkly and started swaying his pelvis more powerfully into the blonde woman’s body fucking her with renewed vigor while she mewled into Rias’s mouth.
Their arms hung around each other keeping the embrace going with their tits squeezing against each other at the same time. Rias hungrily sucked on Lady Phenex’s tongue tasting her saliva while she cleaned out her tonsils in a frenzied manner. Her body rocked and pounded voraciously into Sirzechs’s body, she was moving faster and shuddering harder the longer he bottomed out of her pussy. Rias moaned into her mouth again tasting her while their tongues wrestled in a bout for dominance, the slapping noises of Sirzechs’s pelvis crashing into her buttocks continued unabated with Lady Phenex succumbing to tow more orgasms along the way!
Minutes later, Rias was now on her backside, legs spread wide with hands holding the blonde woman’s head into her snatch feeling her eat her out with insane gee. She moaned and panted laboriously while feeling her tongue wriggle around inside of her sperm-filled snatch cleaning her out and giving her pleasure at the same time. Sirzechs continued fucking Lady Phenex from behind, Doggystyle at first until he switched to spooning her voluptuous naked body with hands grabbing hold of her titties again.
“Mmnnggghhhhh!~” Lady Phenex screamed into Rias’s muff feeling his member now fucking the very inside of her womb with balls throbbing as they slapped into her nether region preparing to blow.
Rias flung her head backward breathing so intense with pleasure that her chest was heaving greatly causing her tits to bounce like water balloons attached to her chest. She was getting ready to cum herself and knew her brother to be approaching the same fate. Seeing him rut passionately into Lady Phenex’s body from behind made her loins throb knowing full well he was about to seed yet another child inside of this woman’s body. It still astounded her that the regal, wise, Maou of Hell delighted in the practice of cuckolding and being cuckolded later down the line. With many bastard products of incest no less, the mere thought of it excited her making her folds quiver as she came a moment later upon feeling Lady Phenex’s tongue pushing up into her clitoris.
“Aaaaaahhhhh!~” Rias cried out in ecstasy lifting her legs up into the air making them quiver as she came all over Lady Phenex’s face the same time Sirzech slammed into her buttocks with a howl.
The Ruler of Hell leaned back slightly as he felt his throbbing member pierce all the way into the blonde woman’s womb feeling his balls imploded sending a thick potent flood of sperm directly inside of it. Upon feeling the molten warmth of his sperm folding into her womb, Lady Phenex came hard into Rias’s muff sending shivers of coital ecstasy throughout her system as they all came together in unison. Lady Phenex’s eyes went wide in wonder once she pulled up from Rias’s snatch with a messy face, she had a blissful smile on her lips as she felt each thick spurt of cum splashing into her womb to the point her pussy was overflowing. No doubt that Sirzechs’s little swimmers were racing towards her eggs ready to leave her with yet another child like Ravel underneath her husband’s nose.
“Nnggaaaaahh!~ Yess! Darling! Yesss! Breed me!” She cried out as her body quivered several more times feeling the thickness of his cum spill out of her pussy and onto the bed as he let out inside of her for several minutes before stopping.
*Throb….throb…...throb…..Splotch!*
Once he was finished cumming Sirzechs pulled out of the woman’s quivering pussy letting a thick splotch of sperm come out just as she slumped down onto the bed happily spent. Rias did the same thing letting her head lay back onto a random throw pillow, her chest continued to heave exhaustively while she took a moment to catch her breath. Both women were stuffed full of the Maou’s sperm likely baking an oven order for his Heirs as we speak.
“There…..*huff..huff.,..hufff*....welcome to the club, my dear sweet sister. I believe you’ll enjoy it here.” Sirzechs spoke out and rested on his back cuddling next to Rias with Lady Phenex curling up on his side running her hands affectionately around his chest. “Once we have a good night’s rest, we can begin discussing how we will take the rest of Riser’s peerage, the female members anyway, out from under him.~”
At hearing this, Rias smiled widely and held her head close to her brother’s neck basking in his scent and relishing the knowledge that she’ll be helping him rob her unwanted husband.
“Ooh, I can’t wait.~” She answered before bringing her lips to his face and kissing him fully with her mouth opening up to swallow his tongue.
