Chapter 6 - Growth & Expansion

Following her return from finding Ddraig, Rias explains the situation to her friends, as well as the waiting period. Koneko took it about as well as Rias had expected, naturally. Following this, things around the House of Phenex became a bit more casual, though a bit much more than to Riser's liking.

Currently, the Head of Phenex lays back in the bath tub, watching as Rias rides away on his cock in the reverse cowgirl position, moaning away without any squabble while she massages her own set of melons. Though his cock may be hard, the joy and gimmick of putting these girls through a phase that made them know their place seems to have finally faded away. This whole time he had thought to himself that the girls would be more phased about his demands for sex, but they seem to find it just as casual a part of their lives than anything else. Even as the crimson haired devil bounces atop his shaft, Riser recalls the previous evening where he had demanded that she let him fuck her, with Rias barely even putting up a fuss. She even lifted the bed sheets off her naked body, rubbing her finger against her pussy just to warm herself up. Phenex still took it, but he found no pleasure out of someone so willing.

Then there's the other two. While Akeno had been busy with cleaning up the kitchen, Riser had entered just after another long business meeting, one he was thankful Rias hadn't ruined. Before he could even finish his demand for a blow job, Akeno had already knelt before him, unzipping his pants to use her mouth to play with his member. Even Koneko, the smallest of his wives and the one he enjoyed torturing the most, casually took to jerking him off over her dinner in order to place his load on her plate. Not because of any particular desire to have his seed, not directly anyway. But because she found her food to be too spicy. The fact the white haired devil, of all people, is so casual about these matters now blows Riser's mind, enough to irritate the poor dope.

Even right now, the general behavior of Rias pleasing him without a snide word or any force from the Head of Phenex baffles him. What had happened? When did this behavior change? Has it simply become clockwork to the other girls? He doesn't have long to think about that question, as he soon ejaculates within Rias's snatch, his cum filling her up well and good before she has her own climax atop Riser's shaft. The Head of Phenex lets out a simple sigh, no change in expression as he tilts his head back against the tub. "Riser is satisfied," he says with a bored tone, "you're free to go for now."

"Glad we could have this session." Rias says, nonchalantly standing up off Riser's lap. After the crimson haired devil leaves the bathroom with her towel, the immortal devil sits up in the tub, musing to himself about these last few weeks.

"Things have become quite boring for Riser," he says, "and it seems to have turned into a very mundane task for his wives as well. Perhaps he can do to the wives, especially the tallest and smallest, what he had done to Rias when she embarrassed me in the middle of that sale. A calmer, gentler Riser that thinks more about the pleasure and needs of his wives..." After a short pause to contemplate the option, Riser smirks, laughing through his lips. "No, that would be too simple for Riser, and a short term solution at that. Perhaps there's something else Riser can do that will really punish his wives. Riser thinks that now is the perfect time for him to up his game."

After getting out of his tub, Riser changes into his clothes, then teleports off to his library.

A little later on, Rias lays atop the bed she, Riser, and her friends sleep in, reading up on the book where she discovered Ddraig's existence. While she lays on her stomach, she taps at her chin while her legs kick about in the air, studying up on further spells that may be of use during this marriage. "Interesting..." Rias says to herself. "So if I were to use this, that means..."

Her thoughts interrupted by the creaking of the bedroom door, Rias quickly tosses the book underneath the bed, suspecting Riser would never consider looking under there for it. "Ah, there's Riser's favorite bride." Riser says upon entry. "Your husband has a surprise for you."

"A surprise you say." Rias says casually. The former Head of Gremory doesn't suspect it to be much, especially coming from someone as unimaginative as her husband. The most likely scenario the crimson haired devil can assume is a bouquet of flowers, only with the flowers cut off the stem and replaced with cum-filled condoms. "Actually, a surprise from you would be any surprise at all. What do you have to offer?" she asks her immortal husband.

"Riser's glad you asked," Riser says with a slight grin. "He's been exploring some rather special magic that he wishes to utilize on you and his other wives. "Feast your eyes on this!" Upon dropping his pants to the ground, Rias's eyes grow wide with shock. When the pants drop to his ankles, Riser's shaft comes to life, though it's much different compared to just moments ago when she saw him in the bath tub. The girth has certainly grown out, as the circumference is wider than before. Its thickness is assisted by the new length Riser presents to the crimson haired devil, which she assumes to be an inch short of a whole foot. Shaking at the sight of it, Rias's eyes turn glassy, her breath heavy as she understands what Riser's plan is for such an enormous cock. "Do you like what you see?" Riser asks, holding his massive extension up for Rias to marvel at. "Riser decided that there needed to be some spicing up around this place, and what better way to go about it than with some growth?"

"I think you're crazy!" Rias says, her body covered in sweat. "That thing might kill me at that size!"

"Why not give it a little tug?" Riser asks with a grin. "Perhaps once you get a proper feel for it you'll think otherwise?" Against her better wishes, Rias grumbles as she holds onto the immortal's rod, realizing that it really is thick, enough that it can barely fit in one hand, though she still manages to wrap it around. Staring intensely at the larger member her husband gave himself, Rias gives Riser a few strokes, the immortal devil sighing of relief as he feels her touch. The source of his joy, however, comes from the sight of Rias's gaze, her eyes reflecting the discomfort as she predicts what will happen with such an extended appendage. The tug session that Rias delivers to Phenex ends when his enlarged shaft stands at full attention, his veins pulsing with blood to maintain its stiffened status.

"Yeah…I still think it's going to kill me." Rias says, reaffirming her beliefs.

"You're too adorable." Riser laughs, pushing the crimson haired devil back on the bed. "Let's give this massive cock its maiden voyage, shall we?"

Holding Rias's arms down on the bed, Riser guides his cock against her vaginal folds, massaging himself against her moistened lips while she grunts, attempting to struggle from the immortal devil's hold on her. With the right thrust and the juices from her lips moisturizing him up, Riser smiles before the head of his enlarged cock pushes inside of Rias's snatch, watching the former Head of Gremory's eyes widen at the first few inches of penetration. With his member stretching her out more than ever before, Rias roars through her teeth, trying to endure to amount of force Riser's thickness provides. The crimson haired devil stares right up at the ceiling, sniffling through her nostrils as Phenex continues to forces his way up her cavern, grunting as he himself seems to have trouble adjusting to his new size.

"Ergh…Riser can't seem to fit all of his cock inside of you…" he grunts.

"Really now, what was your first clue?! Hrrrrrgh!" Rias growls, feeling Riser poking at her cavern walls with his throbbing head, as if the cock were making attempts to move off the trajectory. Giving up on this position, Riser decides to move on.

"Perhaps Riser should try to penetrate you from another angle." he says, using his thick member to lift Rias off the bed. The crimson haired devil cries out, her head and body spinning while she remains impaled due to Riser twisting her around. Soon Rias finds herself back on the bed, this time resting on her hands and knees after her husband places her in the doggy position. With a light chuckle escaping his lips, Riser grabs hold of Rias's ass, gripping into them as he pushes once more into her pussy.

Before his base can reach her backside, Riser feels his cock tensing up, already throbbing for release. Still inexperienced with such a monster, Riser is unable to hold it in, unleashing his sperm inside Rias's pussy without any warning. The crimson haired devil cries out, grabbing the bed sheets tightly as she tries to endure the flood of sperm entering her vagina. "Oh fuck! Fucking hell!" Rias exclaims, the burst of jizz still ongoing. When Riser's ejaculation finally settles, Rias grunts as he pulls back, his own member coated in his seed while more of it floods out of the crimson haired devil's snatch, creating a giant milky mess all over the sheets. For a brief moment, Rias rests, her body sopped in sweat while her hole leaks out the immortal's seed, having gone through an experience like no other before. At least she knew the worst of it would be over, at least until the next time Riser needed his release...

Then upon looking behind herself, the crimson haired devil notices that her husband is still hard, ready for another round. "You can't be serious..." Rias says, heaving for air.

"Riser is always serious." he says, his cock twitching for more. "And he intends to stretch your holes out well, so that he may continue to use them in the future."

"Holes? Plural?!" Upon hearing that, Rias prepares for the worst, cringing as she feels the thick cock head poking against her asshole just before Riser slides it inside, the crimson haired devil biting down on her knuckle as he stretches out her backside. She feels him push deep within her anal cavity, pushing the walls outward to accommodate for his newly expanded dong. Riser simply laughs, striving to push further within the crimson haired devil's anus.

"This works well for Riser," he laughs, jutting against Rias's body to ensure his cock goes further in, "as he'll eventually be able to make you take his cock in both holes. Won't that be...delightful...HNNNGH!"

Unable to keep his erection once again, Riser dumps his next load of cum in Rias's asshole, causing her to bring the bed sheets to her mouth, biting down on them while she feels even more seed flood from Riser in less than a few minutes. Combined with what remains in her vagina, Rias starts to feel her belly expand slightly, growing outwards from all the seed that the devil continued to pump into his wife, who runs her hand over the slight outward growth in her asshole. The second he pulls out, Riser feels another spurt coming out, a light flow of seed trickling onto the crimson haired devil's back. Her holes slowly dripping out seed, Rias's body quivers as she tries to move, though the thought of Riser's jizz dripping out her body as she loses control of her holes continuously springs to her mind.

"Riser...has pleased you...has he not?" asks the immortal devil, clearly out of breath. "This new member has...taken the wind out of him, however. Perhaps a bit of rest will be needed..." With a heavy sigh, Riser collapses onto the bed next to Rias, who stares on at her husband as he slowly passes out. Feeling the need to empty her holes, Rias quickly hops off the bed, rushing off to the bathroom as quickly as she can.

"NNNNGH! Fucking...how much can still be in there?!"

As Rias realizes she's spent so much time in the bathroom, her holes still expelling the jizz that Riser emptied inside her just recently, she looks down at the toilet bowl to see that the milky substance is just nearly touching the rim of the toilet. With a heavy grunt, she flushes the bowl, watching as it safely goes down the drain, hoping that it isn't thick enough to create blockage. Even as the water refills, Rias still feels so much in her needing to be vacated from her pussy and ass.

"At least my stomach returned to normal," Rias says to herself, "but so much cum...I feel like I've been on here for hours. And I doubt Riser is going to return himself to normal anytime soon. Maybe now's the best time to start using that spell I found..." She looks over at the other seats in the small row of toilets, reflecting that they had likely been placed there long before the marriage, accommodating for the large harem Riser had previously...

Before Rias can monologue any further, she looks up when she hears the bathroom door open, seeing her husband walk in with a yawn. "Riser had a good nap," he says, stretching his arms out, "but he was surprised to see that you had left him when he awoke. Now that he knows you're here, he has a good understanding of why."

"I had to get your gunk out of my system," she says with a glare, "it really isn't healthy for me to hold in so much."

"Expelling your genitals does sound like a good idea," says the naked Riser, his enormous cock still dangling between his legs, "as Riser needs to drain his lizard as well."

"I really wish you wouldn't say it like that." Rias mutters.

"Would my wife be so kind as to hold it up for Riser as he urinates? It's still quite heavy to use, after all." Seeing his cocky smirk, Rias reaches out for his massive member without staring at it, holding onto it as Riser releases his stream of urine, a satisfied sigh escaping his lips. The crimson haired devil groans as she remains seated to remove the excess cum, annoyed by the light splashes of the gold stream that splashes onto her body. She's going to need a shower when this is all finished up. When he finishes up, Riser has the gall to moan in delight, Rias feeling his cock grow out once more following his relief. "It seems Riser enjoys the way you touch him no matter the circumstances." he says with a smile. "Perhaps my wife would like to pleasure him with her mouth?"

"But you just..." Rias stops herself, growling at the immortal devil She already knows how poorly this will go for her, seeing as Riser still hasn't been able to properly control his orgasms. Still, she leans into the growing Riser cock, her lips planting themselves around his head. Shivering on impact, the crimson haired devil feels disgusted, now recalling that her husband did not wipe the urine from his slit, with a few drips crawling onto her tongue. Though she wishes she can remove the cock, Riser continues to push into her, Rias's eyes growing wide as he pushes his thick member towards the back of her throat. He laughs to himself as he tries to push himself all the way down her mouth, only to find the remaining four inches are unable to move into her.

"It seems we're going to need to practice on your throat soon." Riser gloats, jutting into Rias in an attempt to stretch her mouth out for his new size. Rias creates glucking sounds from her throat as the immortal devil continues to ram his cock inside her, hoping to reach her lips with his hips. The rod bobs around in her mouth, Rias's eyes wide with fear of having her throat permanently stretched just to accommodate for his enlarged shaft. Fortunately, she never has to worry about that. Unfortunately, it's due to Riser once again being so quick to reaching his peak. The immortal growls as he empties his seed inside Rias's mouth, the crimson haired devil forced to intake everything Riser offers as his head is against the back of her throat. Her stomach fills up quickly with the fluids, causing Rias to grab hold of it while he continues to pour his load within. As her eyes roll back, Rias whimpers as she fears that her stomach will once again expand with such an input of cum, but thankfully it doesn't come to that.

When he finishes, Riser sighs to himself, pulling out his deflating member from Rias's mouth. "A good job as always, my wife." Riser grins. "I'll be awaiting you once more for another round. Don't be long."

Once Riser leaves the bathroom, Rias quickly moves to her knees, facing the toilet. Performing a self Heimlich maneuver, the crimson haired devil barfs up all the milky jizz that he forced her to take, an unpleasant feeling in her body as she pukes the fluids up. Staring into the toilet full of his load, Rias pants in a cold sweat, realizing that she's going to have to go another round with Riser before she can cast that new spell on herself or the other girls...
