*A few weeks back*
"I finally did it!" Anne cried as she slammed down a couple small vial-like bottles onto the dinner table, stunning everyone slightly as they looked up from their meals at her.
"What did you do?" Alex asked her curiously, making the dark skinned beauty beam with pride as she gestured to the two bottles and said,
"These are the solution I made up after investigating the flowers Mizore gathered from the Yuki-onna village, which will almost completely assure conception of a child for any woman that drinks it!" Anne then went on to explain the effects of the solution she made, which supposedly ensured conception as long as the woman tried to conceive a child within six hours of drinking it, while it also functioned as a form of aphrodisiac similar to the original flowers. As she had been in the middle of explaining it though, Xenovia suddenly asked,
"Have you already tested it on someone?" Anne shook her head before saying,
"It was more or less the original function of the flowers to begin with, I just made it consumable and strengthened the part to help conception a little bit, with Momo's help of course." Everyone turned to look at the youngest of the Devilukian sisters, who immediately acted shyly to the attention she was getting before saying,
"Oh I didn't do that much at all, I just showed miss Anne some of the flowers I've seen in our universe that have similar effects, she did all of the actual work." As Momo tried to brush off her involvement in Anne's work, Xenovia then asked Anne with an intense look in her eyes,
"So if they aren't tested, do you need a volunteer?" Knowing where she was going with this, and with everyone else gaining an intense atmosphere after words, Anne said exasperatedly,
"Well that's why I only brought two bottles, in order to test it ourselves. That being said, we need to exercise restraint since we already decided against having too many more children right away, which is also why I'm planning to have these be prescribed instead of people just being able to acquire them whenever they want." This time everyone grimaced at her words, as they remember a discussion they had not too long ago to officially wait until Alex's current children matured a little bit before having more, in order to prevent having so many children running around at almost the exact same age. It appeared however that Anne was planning the same thing for Asora when she finally revealed her new creation, to prevent all of the couples that have longed for children for decades, or even centuries, from getting pregnant all at once.
Now the question was who would get the two test bottles?
The atmosphere turned even more intense as this very question passed through the mind of every girl present, with a powerful holy energy appearing as Xenovia began summoning her Excalibur and Durandal. Things ended rather anticlimactically though when Rias picked up one of the bottles and plainly said,
"I've been in a relationship with Alex the longest out of everyone here, so I'm taking one." Instead of trying to argue with her logic, the rest of the girls set their eyes on the remaining bottle before Akeno proceeded to pick up the other bottle while saying,
"I may overlook a short time, but I don't want you to steal too much of a march on me when it comes to having Alex's child Rias, ufufufufufu." The rest of the girls then pointedly looked away as Akeno claimed the second bottle, as none of them wanted to get on her bad side only to wake up and find themselves in her dungeon one day. Smiling wryly at the turn of events, Alex then said right as Rias and Akeno began making plans for that night together,
"Rias, I'll just have you tonight. Akeno, I hope you don't mind waiting a day or two since this is relatively different compared to usual." To Alex the act of purposely making a child was a lot more meaningful than simply indulging in their lust, and as such he wanted to put a bit more thought and emotion into how the night went than he usually did when that was their intention. And in the pursuit of providing a 'meaningful' night for Rias, Alex already had an idea thanks to Lala's newest invention that she recently completed.
When he started getting lost in his plans for Rias later, Alex was suddenly aware of Akeno creeping up to him seductively, before saying, "Alright then, I'll let you do things your way master~. But in return I'll make my own plans regarding our time together, look forward to it, ufufufufufu~."
She then turned and started walking away without giving Alex time to respond to her declaration, her hips swaying seductively. Smiling wryly at her words, Alex wondered for a moment what Akeno would have planned before he decided to focus his mind on Rias for the time being since she was the one he would be with later.

Later after having her bath Rias made her way up to Alex's room, her heart pounding with both nervousness and excitement as she held the bottle in her hand. In her mind she was recalling what Anne told her while they bathed, that to be sure the serum worked properly Rias and Alex couldn't go at it several times like he usually did. Though this particular restriction was bound to be tough on both of them, as Rias had long gotten somewhat used to Alex's endless stamina, she felt the frustration would be more than worth it if she managed to have a child.
With these thoughts swirling through her head, Rias then uncorked the bottle and downed the contents as she approached Alex's bedroom door, though it wasn't until after she swallowed it that she recalled that the serum also acted as an aphrodisiac. With a potent heat spreading through her body quickly, Rias opened Alex's door to find him casually sitting inside as he waited for her.
When he saw her an affectionate expression showed itself on Alex's face, as he stood up from his bed and said, "Rias, it's finally time." A warm feeling filled Rias when she heard him that had nothing to do with the rising heat in her body, as she recalled everything shed been through with Alex leading up to this moment.
He then approached her and gently wrapped his arms around her from behind, before leaning in closer to her and whispering into her ear, "Close your eyes, I have a surprise for you."
With her heart rate increasing rapidly, Rias did as Alex asked and closed her eyes for whatever he had in mind, except that he never released her from his gentle hold. Instead, after several seconds he finally said, "Open your eyes now." When Rias opened her eyes she felt as if her heart would stop at what she saw.
In front of her was a small lake surrounded by a forest with hundreds of fireflies dancing through the air. What had surprised her so much though, was that it was the exact same place where she and Alex had their first time together after he had saved her from her engagement with Raiser Phoenix, complete with even the purple sky and artificial moon from the underworld. Though she only noticed it a few seconds later, she had also been changed out of the robe she wore to Alex's room into a dress like that she would wear to a high society party, while Alex was in a suit.
"H-how?" She sputtered as she tried to figure out how this was happening, which she could tell it wasn't an illusion due to the fact that she could smell the earthy aroma of the forest around them, along with the gentle breeze that blew through her hair. Alex smirked and explained,
"It's Lala's newest invention that she prepared for me, called the Love Room. It uses the same virtual reality tech that the virtual world's she created for Nana and Momo's friends, except in here there are several hundreds, or even thousands, of different scenarios for us to choose from to have fun with." Then to give Rias another example, Alex summoned a digital interface that was tied to the room around, which only he, Lala, and Momo could access.
A second later the world around them started distorting, until the duo found themselves in another very familiar place with a very different set of clothes. "Oh my god!" Rias emotionally exclaimed as she took in the room around them, which was their old Occult Research Club room, along with their old school uniforms.
With nostalgia momentarily suppressing the heat in her body, Rias stepped away from Alex's embrace to look around, only to find that everything was exactly the way she had left it. Before she could get too engrossed though, the scenery changed around them once again and she found herself in the same dorms that she had lived in with Alex and the female members of her peerage so long ago. Before she could get too absorbed in looking around though, Alex embraced her from behind once more and whispered into her ear,
"No matter the scenery or scenario, this room could reproduce it exactly, even something like this." As the last word escaped his mouth the world changed again, except Rias's heart almost stopped when she realized they were in the middle of the same mall that she used to go to all of the time, wether to shop with the other girls or for a date with Alex. The only difference was that this time they weren't the only ones there, as dozens of familiar faces made their way though the mall as they went about their business.
"What is this?" Rias demanded as she suddenly recalled the arousal coursing through her body. Alex's smile widened as he tightened his embrace on her, and he said,
"These are programs based on people who would be found in these environments, basically they're like the npc's you'll see in video games. Though they aren't real people, they'll still react if we did something like say this!" As he finished Alex suddenly grabbed and pulled up the front of the school uniform skirt that Rias was still wearing, while simultaneously making the panties underneath vanish. The result was Rias's bare pussy being flashed to everyone in front of them.
"Hey, do you see that?!" One guy called out to his friend, while pointing directly at Rias's exposed crotch.
"Are they filming something here?"
"Is this some kind of prank?"
After the first guy called attention to them pretty soon everyone they could see was converging onto Alex and Rias, before several of them then began pulling out their phones to record the scene before them.
"Hey, isn't that Rias onee-sama?!"
"It is! And thats Alex senpai!"
Pretty soon people then began to call out Alex and Rias's names to the gawkers, who were supposed to be their fellow students from school. Of course the entire time Rias was squirming to try and cover her exposed sex, but she had to deal with Alex keeping her from doing so while simultaneously fighting the rising arousal in her body. The worst part though was that her exposed nether regions were becoming increasingly damp as more and more people converged to stare at her, until Alex finally had mercy and changed the scenery and clothes back to the lake.
"Well that was a taste of what this room could do now, but let's stick with this scene for the moment." Alex said casually, making RIas almost tear up a she cried out,
"What taste?! Do you have any idea how embarrassed I was?!" Alex's only response to her words was to smirk though, before said while pointing at her nether region,
"You seemed to like it though, and did you forget that they aren't actual people? They're just computer programs designed to interact with us to a certain extent." When he said this Rias was at a loss for words as she just recalled that they weren't actually people, but they had been so lifelike that she couldn't get that particular scene out of her head.
Before she could try to wrap her head around what was happening though, Alex suddenly swept her up into his arms and said with a cheeky smile, "Well, let's just forget about that for the moment and move onto what we came here to do!" Instead of giving her a chance to respond, Alex immediately jumped into the lake before them.
"Kyaaaaaaaa!" Rias cried out as she entered the chilled water, before she resurfaced and gasped for air with her wet hair plastered to her face and body. A second later Alex resurfaced next to her and, before she could protest, grabbed her by the waist and pulled her closer to seal her lips.
Though she initially wanted to scold him for his actions, Rias found herself melting in the warmth of Alex's touch as the heat in her body rose once again, and this time there was no holding it back. She didn't even notice as Alex slowly brought them back to land, and one of his hands started to slowly make their way up her legs.
As he pulled them both out of the water Alex gently laid Rias down on the grass below them, prompting her to spread her legs to make room for him on top of her. With one hand making its way to the treasure hidden beneath the dress she was now wearing, his other hand eagerly pulled down the top part of her strapless dress to free the constrained breasts within.
"Nnng!" Rias moaned against his lips as Alex's hand began skillfully kneading her right breast, while his other hand had finally reached the soaked piece of cloth that once again guarded her privates. Instead of using the Love Room's technology to dispel the panties like he had earlier though, Alex decided to show more of his aggressive side and simply ripped them off, before his fingers finally began probing the heat emanating from between her legs.
Soon Alex stopped kissing Rias and moved his head down to take her free nipple into his mouth, while her other one was being pinched between his forefinger and thumb.
"AHHHHHHH!" Rias's cries echoed in the surroundings as Alex skillfully assaulted her most pleasurable spots with his mouth and fingers, with the only pauses being when he alternated between Rias's nipples with his hand and mouth. Eventually though his presence disappeared, making Rias open her closed eyes in confusion, only to see Alex's head vanish with the confines of her soaked dress.
Within he could clearly see his quarry before him, a vertical slit at the center of the fork between Rias's legs, topped with a neatly trimmed patch of Crimson hair and dripping honey. Without a single hint of hesitation, Alex's mouth latched onto the hot and steamy slit and dug his tongue within it, making Rias cry out in ecstasy the loudest so far as his hands firmly grabbed her outer thighs to prevent her from moving too much.
He then thoroughly explored every nook and cranny, every fold of Rias's most precious place with his tongue, making her practically scream in pleasure as her hands reached down beneath her dress to run her fingers through his hair. Alex smirked into Rias's pussy as not only did her place her hands on the back of head as if to keep him from moving, but she even seemed to try and sandwich his head between her thighs while simultaneously wrapping her calves around his head, effectively smothering his face with her snatch.
With her seemingly not 'allowing' him to breath for the time being, Alex readily took that challenge as he then decided to figuratively take the metaphorical gloves off and dragonfied his tongue to immediately probe her depths with it. Within seconds Rias's body began spasming as an intense climax wracked her entire being, making her body tense up for nearly an entire minute as she issued a silent scream, only to let her limbs fall limply to the side as she panted deeply.
Smirking with satisfaction as he pulled his head out from within her dress, Alex then grabbed the hem of that same dress and roughly tore it open from the bottom to the top, fully exposing Rias's body to his gaze. With the sound of tearing cloth bringing her back to her senses, Rias looked up at Alex with unfocused eyes until he brought his face close to hers.
With her own smile on her lips, Rias linked her arms around Alex's neck and brought his mouth down to her lips. The two began to kiss affectionately and passionately as Alex used the Love Room's functions to remove his own wet clothing, before Rias finally broke off their kiss and panted into his ear,
"Please, give it to me..." It didn't take a genius to tell what Rias wanted him to give her, and so, Alex lined up the head of his cock with her waiting hole, before plunging the entire length in all at one time.
Once more Rias's screams filled the forest around them, but they weren't screams of pain at the sudden penetration. With her burning hot insides wrapping and squeezing his cock perfectly, from him having long molded her insides to his shape and size, Alex began to slowly piston in and out of her while the Crimson haired woman cried out in ecstasy.
Back and forth Alex moved in slow repetitive motions as he made love to the first woman he had become involved with since reincarnating, preparing to plant his seed deep within her. Rias herself held Alex as closely as possible with her arms around the back of his neck, and her legs wrapping around his waist as if to keep him from escaping.
This continued for several minutes until Alex felt a pressure begin to build within his loins, and Rias felt him twitch noticeably within her. Soon both of them let out a small gasp as Alex unloaded as much of his seed as possible into her womb, and Rias felt her insides being pumped full of burning hot fluids.
Normally this was only the first of several rounds the duo would go through in the night, but, with Anne specifically asking them not to indulge themselves after the first time, Alex held himself back from continuing as he simply kissed Rias gently while she returned his affections. He then rolled over so that she was laying on top of him with her breasts squished against his chest as she said,
"That was amazing...thank you for all of this...." Though she was obviously referring to the child they had just made, Rias was also thankful to Alex for showing her everything he had beforehand, of course with the exception of what happened in the mall.
As she recalled everything they had been through up until that point, and everything they had left behind, Rias felt an overwhelming urge to return home to see her family again so that she could recount every detail to them. The worlds they had seen, the people they had met, and different marvels were all things she wanted to recount to them. And then, as she gently rolled off of Alex to lay next to him, Rias placed her hand on her abdomen as she thought about the thing she wanted most to show her parents.
The duo then laid there cuddled up together as they watched the fireflies, and discussed possible names for their future child. Naturally Rias, who was obsessed with Japanese culture, wanted to give their child a Japanese name, and seemed quite taken with incorporating their draconic heritage into their name as well. The only thing that kept them from getting too into the naming though was that they would not know until the child was born if it would be a boy or girl(every one of Alex's wives preferred the surprise more often than not).
And so the duo laid there together silently, simply enjoying the warmth of the other without even considering going to sleep. Though, after a while Rias felt the heat that had been coursing through her body earlier resurface, as the last remaining vestiges of the aphrodisiac made their presence known. With her legs starting to fidget from how uncomfortable the heat was making her, Alex soon asked,
"Is something wrong?" Rias looked up at him with confliction on her face before she finally admitted,
"I'm still feeling the aphrodisiac...." Alex cocked an eyebrow at her admission, before saying,
"We can probably remove the effects if you want-"
"No! Then it might prevent me from getting pregnant as well..." She then seemed to struggle with something before the Crimson haired woman eventually got up from Alex's side on all fours and said, "We can't do it like normal, but maybe something else..." She then did something that completely stunned Alex as the Crimson haired woman then pointed her butt at him, and gingerly reached back with one hand to spread her cheeks open, presenting the wrinkled little hole within to him.
"This is a one time thing, so you better enjoy it." Rias said reluctantly, as she never had an interest in letting him put it in 'there' before. But with the aphrodisiac fueling her desire, and the fact that she would have to go without being in Alex's bed for quite a while now, Rias decided to make an exception.
With Rias offering him a new and enticing experience with her, Alex had a large smile on his face as he placed his still wet dick at the tightly puckered little hole, before slowly thrusting his hips forward to penetrate her incredibly tight ass.
The next day, a very sore Rias would go to Anne and recommend lowering the quality of the aphrodisiac with her serum, and after nine days/months in the space-time orb she and Alex eagerly welcomed their son Ryoto into the world.
