A/N: Another Izuku x Rias story. I just felt like doing this one. Plus, I know that the majority of the Izuku x Rias fans would love to see some spicy moments between the two. Am I right or am I right?

A normal day as usual. At least for Rias anyway. Every day starts with waking up butt-naked next to the only man in the entire world she considers worthy to be her husband. Izuku Midoriya.

Ever since she joined Kuoh Academy, she has experienced the typical life of a rich girl. And a beautiful, drop-dead sexy one at that. She pretty much expected to be asked out by several guys just as soon as they lay their eyes on her. She can thank her Devil bloodline for that. But she knew that those eyes weren't directed at her. The person behind the name Rias Gremory. No, it was directed at her body. Her voluptuous and bodacious figure. Those were eyes of lust.

She despised those types of boys. She never even wanted to find a special person in her life. She was content with living by herself surrounded by friends and family. But if she were to find a lover, she preferred someone who sees her for her and not for the name she carries. Being a princess in the Gremory household, a famous Devil bloodline in the underworld, she was placed on a pedestal by many people, both old and young. They had expectations of her that she cannot ignore. So by interacting with a person who has no care for her status or name, she would feel free from all those expectations. Free to be just Rias.

And she found that one person to be the green-haired teen sleeping peacefully right next to her.

He was the only boy who wouldn't dart his eyes at her female parts and would rather look into her own. Like he was looking at Rias and not Rias Gremory. He joined the same year she did, and became good friends with her as well as her peerage (without him knowing their devils). She found herself to be practically enjoying his company. The sight of his freckled face, which she claims to be utterly cute, would just bring a smile upon her face. He was an introverted individual with not much social interaction. But he became used to hanging out with her as well as other people.

A year later, she finds a very interesting secret about him. He was this generation's host to the White Dragon Emperor. And at this time, her parents had informed her of a potential marriage partner who was from a Devil bloodline of similar status as her own. His name was Riser Phoenix, heir to the Phoenix household. But she was never interested in him in the slightest because he was just the like the boys who would look at her for her body and status. But she had no say when it came to her life decisions. Her life was practically decided by her parents. It was understandable since their Devil race was facing a huge reduction in the population of pure-blood Devils. But still, she wanted to make her own decisions regarding her life.

In order to completely cancel this marriage, she had one way out.

Rating Games.

But much to her chagrin, Riser was experienced in that field. Having a complete set of Evil Pieces, he had won many championships in the Rating Games. She lacked the experience he had. But she wouldn't give up. She just wouldn't because she knew her life would go down the drain if this marriage would come to fruition. And now, her only chance is Izuku, who happens to hold the power of the Vanishing Dragon, Albion. A Sacred Gear by the name of 'Divine Dividing'. She planned to recruit him into her peerage.

But imagine her surprise when he personally comes to her base of operations and offers to help her with her plan of canceling the marriage. She was confused and surprised by the fact that Izuku was already well-informed about the supernatural. What's even more surprising is that he was already part of a peerage.

Her maid's peerage. That maid specifically Grayfia Lucifuge, the strongest Queen. Queen to Sirzech's peerage.

A queen to the king who is a queen to another king. Huh! Who would've thought about that?

She was happy nonetheless to receive his help. And they succeeded in taking down Riser in her first Rating Game. After this, Rias came to realize something. Something that had been bothering her since she met Izuku.

She was madly in love with Izuku. And for all the right reasons too. Which girl wouldn't fall in love with a sweet, and caring guy like him? A gold-digger?

Maybe but besides that.

Anyway, now that she knows Izuku is the one for her, she can only confess and hope for the best. And this is where Rias comes to learn a very important aspect of the world of love. Love rivals. And several ones at that. Two of them are Akeno and Grayfia, who she considers sisters. Which meant that she had to fight for Izuku's affection.

Oh boy! She was in for a ride.

Present time

Rias opened her groggy eyes. She was still tired and was not in the mood to wake up. She found herself to be staring at Izuku's sleeping face. She smiled as she hugged the taller boy closer to her. His head nearly pushed into her heavenly bosom. She cherished these moments together with her crush. He still hasn't responded to her feelings yet. She had confessed to him during their graduation but got no response from the green-haired teen. But she was patient. Whatever his answer was, she would learn to accept it. She got up to drink a glass of water and then got back to sleeping with her body pillow.

She closed her eyes, her mind falling into unconsciousness. But several minutes later, she opened her eyes again to find something very very unexpected. One that she had been waiting for.

Izuku used to live a good life when he was young. He made good friends, had fun with them, and did a load of stuff. But it didn't last long though.

His happy life was cut short due to an altercation with a group of strange people with bat wings on their backs. His parents were stabbed to death, the strange group nearly ended his life. But he was saved by an entity that he would later learn to be Albion, the Vanishing Dragon. Said entity provided him the power to eradicate these people who were called Devils. Soon afterward, he met what he could consider and outright claim to be the most beautiful woman on the planet. A woman with a drop-dead sexy figure, that was somehow sculptured by the goddesses themselves. Silver hair and red eyes that make her appearance look all the more appealing. She introduced herself as Grayfia Lucifuge and she claimed to be his guide from then on.

At first, Izuku was confused. But it soon made sense once she began to carefully explain the world that he lived in. He was no doubt surprised to hear that the world was filled with the supernatural, especially related to the bible. The power that he possessed was called: 'Divine Dividing'. A power that is able to half the power of his opponents and add that halved power to his own. His Sacred Gear is displayed in the form of dragon wings.

Izuku couldn't help but accept the reality of his situation. With the new knowledge of the world he lived in, and with the help of Grayfia, he began his new life as a host to the Vanishing Dragon. This generation's White Dragon Emperor.

He enrolled in Kuoh Academy and made a few friends. He got along with them pretty well. It reminded him of his early childhood. They were really nice people, amongst a few others. Out of all of them, the most he felt closely connected to was Rias Gremory. He had to admit, for a girl her age, she was mature in more ways than one. And the same could be said for Akeno Himejima. Both of them tease him a lot but he didn't mind a bit. It was actually refreshing to be treated like he was part of a family.

Over time, he became closer to all of them. Even more so with Rias. Izuku never wanted to pursue romance in his life, feeling that he was not cut out for it. But that didn't mean he couldn't have feelings for the opposite gender. Especially when the girl is incredibly sexy and has red hair. Yeah, he kind of realized he has a thing for redheads. But he wasn't attracted to Rias for her bodacious figure or her pretty looks. No, he was attracted to her for what she means to him. Rias was a very kind, generous and sweet girl who jumps at the opportunity to help others in need. She was also a very protective friend to him and others in her circle of friends. She would show a rather cruel side that he finds somewhat scary but at the same time endearing. He fell in love with her for that.

So when Grayfia told him to help her master in her fight with Riser, he didn't even need to think to say yes. He helped Rias with her marriage issue and he wanted to confess right after the game was done. But he felt like he was out of her league. A rich, kind, smart, and beautiful girl like Rias was someone he could sweep off her feet. While she was up there at the top, he was down at the bottom. He felt that he had no chance with Rias at all.

So you could expect him to be caught off guard when she suddenly confessed her feelings to him. Izuku didn't answer at all since he felt it was so sudden. But it wasn't like he wasn't going to respond to it. He waited for the right time to tell her that he loves her back. And he knows just the right thing.

Present time

Izuku woke up to find a sleeping Rias in front of him. He felt himself being hugged into her naked body. Her hands were pushing his head onto her moderately large bosom.

'I guess there is no time like the present' He thought.

Izuku began rubbing his hands on her smooth skin. Smoothly gliding over the curves of her sexy figure. He wonders how a girl her age is able to attain a figure like hers. He'll have to ask Grayfia about that later. His hands went to her perfectly round breasts, lightly squeezing them. A slight moan escaped from Rias. But Izuku continued to fondle her breasts. In the past, Izuku would peek at her breasts and admire their shape but only for a split second since he didn't want to be noticed. Now, he has 'full' access to her chest. He almost feels guilty for not asking her permission but he knows just how perverted Rias is. He noticed the advances he and Akeno made on him. And he knew what they meant. Akeno was a different story (A/N: Quite literally). But Rias was...was...something else. He couldn't put it in words but there was something that compelled him to go along with it.

Now he knew. He was just attracted to her. Both romantically as well as lustfully.

As he continued to massage Rias's breasts, she kept moaning in a soft voice. She was still asleep and had no idea. But Izuku knew she wouldn't be for long. He smoothly ran one of his hands down her body to her nether regions. Rias's moans only increased when he began playing with the outer labia of her exposed womanhood.

'Does she shave on a regular basis or what?' He thought, as felt the prickly skin of her pussy. Getting another idea in his mind, he slid down to the bottom of the bead and lifted Rias's legs over his head. He positioned his mouth over her nether regions and began eating her out.

Not long after, he felt his hair being grabbed by two hands. He looked up to see Rias, awake and surprised. But she smiled soon after.

"What took you so long, you bastard? Do you know how long I waited for you to do that?" Rias asked. Her heart skyrocketed when she saw Izuku eating her sacred region out. Her hard work finally paid off.

"Let me give you a piece of advice. Never make a woman wait." Rias told still grabbing his hair.

"Yes, ma'am" Izuku said, as he continued to eat Rias's pussy out. This time, Rias's moans were louder now that she was fully awake. She pushed Izuku's head further into her womanhood, urging him to continue.

"Ahh~ Izuku, right there~ Right there baby! Right there! Ohhh!" Rias was loving the feeling of her pussy being pleasured with Izuku's mouth. Her climax was coming near.

Wanting to make her feel good, Izuku slid a finger into her pussy and back out. In and out. He repeated the process several times. This only made Rias's climax drive further to the finishing point. Until...

"AHHHHHhhh~~" Screamed Rias as her body shook with pleasure from her climax. Izuku wasn't ready for a torrent of Rias's love juice to be sprayed on his face. But he lapped up the most that he could.

"Haa...haaa...haaa..." Panted Rias as she was still recovering from her high.

Izuku hovered over her body as he brought his face closer to hers. Seeing Rias's face beam with pleasure, brought a smile to his face. "How'd I do, ma'am?"

"Wonderful, Izuku. Just wonderful" Rias said with a happy smile. She grabbed his head and brought him for a passionate kiss. Izuku complied happily as he rested his whole body on hers. Both making out like there was no tomorrow.

Izuku switched their positions with Rias now on top of him, still in liplock. He grabbed her bountiful ass and began massaging it, earning him cute moans from Rias.

Rias was loving the attention Izuku gave her and her body. Not wanting to feel left out, she grabbed his penis and moved her hand up and down its shaft. They were now battling with their tongues but neither didn't feel like it was a battle. They just enjoyed the feeling of each other's tongues playing with each other. Both of them were in full eye contact.

After a few minutes, Rias went down to his penis and wrapped her large bosom around it. She began moving her upper body up and down, pressing her hands to the side of her breasts in order to fully wrap them around his penis. Izuku groaned at the soft sensation around his manhood. His groan gave her the motivation to further press her breasts around his now throbbing penis.

For a good several minutes, Rias continued to bob her breasts up and down until an idea formed in her head. She bent her head down and licked the head of his cock. This only earned more satisfying groans from her lover.

"Rias! I'm close!" Izuku said, feeling his climax nearing.

"Let it all out" Rias said as she went faster and faster until...

"NNNNGGH!" Izuku jutted his hip upwards as finally ejaculated, his white semen falling on Rias's chest.

Izuku panted while supporting himself with his elbows. He looked down to see Rias scooping up his semen and licking it off her fingers. The sight made his penis go, "ROUND 2 BABY"

"You look so hot right now" Izuku said. Rias swallowed the last of his cum and then looked at him.

"Thank you, my love. So are you ready for more?" Rias said sultrily as she crawled on top of him, positioning her vagina over his penis.

"Ready as I'll ever be, sweetie." Izuku said as they both smiled at each other lovingly.

Rias lowered herself onto his cock, slowly letting it slide into her sacred cavern. Initially, she could feel the pain of her vagina getting stretched out, by an above average penis no less. But the pain slowly converted to pleasure as she could also feel her inner walls being massaged by his hot, throbbing dick. She then completely straddled Izuku with his penis fully in her pussy. Both let out their moans of satisfaction at the respective feelings of being conjoined at the hip.

For Izuku, this was AMAZING. The feeling of his dick being clenched by Rias's vagina was so good that it was almost addicting. For Rias, it was the best feelings she had ever felt in her life.

'So this is sex, huh?' Both simultaneously thought.

"Are you okay?" Izuku asked, concerned. Rias smiled at his thoughtfulness. That was one of the many things that made her fall in love with him.

"Never been better, my love." Rias said as she began moving up and down. Every time Izuku's penis went in and out of her pussy, she would let out a moan to express her feelings of pleasure. Izuku grabbed her hip and moved his hip upward whenever she came down on him. The feeling only heightened their pleasure. Rias moaned louder and began moving slightly faster.

Soon enough, both were moving even faster than before. Izuku could tell that Rias was nearing her climax, seeing how fast she was bouncing. In fact, he was just as close as her. He sped up his movements while grabbing Rias's breasts and squeezing them roughly.

"AH~ AH~ AH~ AH~ I-Izuku AH~ AHhh~ I-I'm cumming!" Rias said.

"Let's do it together," Izuku said, reaching his hands out to her. Rias intertwined her hands with his. She bounced fiercely on his penis, trying to finish off their final climax together.

Izuku suddenly jerked his hip upward into her hip, which drove them both to the edge.

"AHHHH!"
"NNNNGH!"

Izuku's hot sperm spurted out into Rias's womb. Rias enjoyed the feel of his semen entering her baby room. After a few minutes, Rias fell on top of Izuku, hands still interlocked. She looked at him and brought her face to his for another passionate make-out session.

Both of them stayed like that for as long as they wanted to, kissing and holding each other.

"That was...amazing, Izuku" Rias said, feeling content with how her morning had started. In truth, she had never expected Izuku to be this bold and daring. But she was nonetheless happy.

"I'm happy you liked it. To be honest, I was kind of scared of what you'd think of me if I did this to you." Izuku said, hugging his lover closer to him.

"That was the best morning sex I've ever had. That was my first time too" Rias said.

"Oh! I'm so sorry. I ejaculated in you. I uh-" Izuku panicked as he remembered.

Rias just stopped him from further panicking by shutting his mouth, "Relax. I put a spell before we became one. So you don't have to worry about anything, my love"

"Phew! That's a relief." Izuku sighed.

"I'm tired. Can I sleep on you?" Rias asked, with a cute face.

"Go ahead. I'm tired as well."

"Mm"

Both comfortably slept for a few more hours into the day. Since it was a holiday, they didn't have to worry about their college.

But what they did have to worry is the fact that they were being listened to by two people outside their room. Specifically, Akeno and Grayfia who came to greet both Izuku and Rias good morning. But they didn't want to disturb the newly-formed couples moment so they individually decided against it. But they couldn't help the jealousy in their hearts.

'You may have the lead this time, Rias. But I'm not one to give up on something I want. Especially, Izuku.' Akeno thought. She was happy for her master, but she also loved Izuku just as much as Rias did. After what Izuku had done for her, she wouldn't just quit here and now.

'...Can I still be with him?' Grayfia thought. For a long time, Grayfia had harbored feelings for her 'Queen' ever since she found out just how much of a good person Izuku was. And he was really dependable in her time of need. Being a maid for the Gremory household can have its toll on her at times, and its those times that Izuku becomes her pillar of support. For everything that Izuku had done for her, Grayfia was grateful for a person like him. And she wished she could further her relationship with him in the future.

A/N: Aaaand done. Now I know I was gone for a very very long time. Please put your guns down and let me explain.

I was occupied with college work as well as new hobbies. I've recently been watching rom-com videos on Youtube. Initially, they were fun to read. But the more I read, the more I realized how much more I have to learn.

But now, I'll try my best to be on schedule. I don't wanna disappoint you guys.

Anyway, Rate and review this little spice one-shot. Hope you liked it.

Do you want me to make similar one-shots for the other DxD girls as well? The next girl I'm thinking of is Irina.
