Author's note: Sigh, so I tried writing smut. This was just experimental, really. I might write more depending on the response. But do give any tips to improve please. I want to experiment writing various stuff and improve on it, smut included.

Also, this is situated in an universe where a 'Roswall' never existed. Subaru was summoned way before cannon and became the king of this word. He's truly a LustBaru in this one.

Chapter 1: Ram

In a dimly lit room, situated at an atrociously lavish mansion, something incredible was going on. The room's temperature was higher than it should be. And from inside, came the rich sounds of love making. The sound of skin hitting skin, the sound of muscle meeting muscle, and the sound of two bodies conveying their feelings to one another.

Holding onto a petite ass, Natsuki Subaru was relishing in this gift granted to him by the heavens. Thrusting with all the intensity that he could possibly muster, he used his hips with complete momentum. His penis slid in and out of that delicate pussy. His plunges struck her beautiful body with force. With each strike, with each move, he saw her skin shake in pleasure.

The wetness of her insides and the feeling of her membranes filled him with pleasure. But he could not let that get to him. His main purpose tonight was to give as much pleasure to his opponent as possible. And so he thrusted with force, reaching deep into her interior and relishing the feeling of his tip hitting her walls.

From time to time he would change his rhythm. Slowing his pace as if he were driving through a residential area, he would gently guide his vehicle into her. Sometimes he slowed to a complete stop, which elicited an annoyed groan from her. Always keeping it unpredictable and not allowing her to guess his next move. He softly caressed her buttocks. Sometimes he wanted to smack it slightly, but refrained in fear of her potential reaction.

But the pleasure in Subaru's body had gotten to its limit. Pulling out his stick and only leaving the tip in, he forcefully brought her own body towards him. Keeping himself steady, he only moved her body. Allowing his pleasure to reach his brain, he kept going rougher on her. The sound of meat hitting meat and the moans that she desperately tried to hide reached his ears.

"Ah- Goddammit, I am coming, Ram!"

A desperate yell that Ram would surely tease him later on, was released from his mouth. Along with that, the contents of his epididymis was released inside her. Each thrust of his was accompanied by a release of his semen. Hot liquid collided within her pussy, as he kept thrusting. Soon, his intense orgasm reached its end and his motion came to a stop. His dick that parked itself inside her, stayed there as it kept releasing its content.

With cum dripping from her pussy and sliding down her legs, there she was. The prodigal Oni-twin, Ram was crouching on all fours as Natsuki Subaru's sperm permeated inside her. Her tiny back was heaving with exhaustion and her entire body was sweaty. Because of the dim light in the room, her pink hair was shining brighter than usual.

In order to hide her pleasure filled moans, she had used the pillow below her to cover her face. But the sound was still heard, and the pillow was soaked with her drool and tears. She would never admit that all of that was due to the sexual prowess of her partner. She would never admit that she had already reached orgasm, multiple times in just twenty minutes. Her lover was that annoying man, after all. But unfortunately for Ram, she loved that man and he loved her.

And even that thought alone, made her heart and her vagina tighten.

Looking at that back and feeling the emotion presented to him, Subaru was aroused once again. Not wasting any time, he flipped her over and threw the pillow away from her face.

"Wha- Barusu, what the hell?! Haven't you had-" Haven't you had enough? Before she could even ask that question, the answer arrived directly at her lips.

Subaru's lips met with Ram's. The soft and small sensation of her lips only served to arouse him even further. Slipping his tongue inside her mouth, he connected it to her own.

Staying like that for a good long minute, he noticed her soft hands caress her back. As much as he wanted to stay there forever, he knew he could not, considering that the erection of his penis was killing him.

Separating from her and leaving behind a trail of saliva between them, he did not fail in noticing the lonely expression on her face.

Without wasting a second, he began thrusting inside her again. Holding on to her legs, he buried himself inside her.

"How the hell could I even have 'enough' of you, Ram?! When this tight pussy is just begging to be filled? Rather, even if I tried to pull out completely, the pleasure would just suck me back in."

"H…ah..This…is why..you are nothing but a pervert. LustBaru!"

Speaking softly between moans, Ram spoke with indignation.

But looking at that angry face of her, aroused Subaru even more. Those tiny drops of tears caused due to her pleasure, fell down her cheeks. The uncontrollable blush on her face traveled down her body and the drool from her mouth displayed its delight. But even then, her eyes stayed sharp and strong. And those same eyes were mired with a proud Love.

This time, Subaru did not hold anything back. Arching his hip upwards, he smacked it into her again and again. Her strong legs grasped into him, inviting him inside.

Of course, Ram tried to hide the pleasure on her face by using her arms. But unfortunately for her, both her hands were grasped by one strong arm of Subaru's and placed over her own head. She could easily resist if she wanted too, but the intense thrusts of her partner had drained her of strength.

Softly and quietly, Subaru placed his other hand on her small breast and caressed it. And then without warning, he used his fingers to roughly pinch it. The pleasurable and painful expression on her face, and the clenching on her insides, drove him onwards.

Soon and without warning, Natsuki Subaru came inside once again. Shivering in delight, he felt all his semen get sucked out.

Looking at Ram who was still experiencing her intense orgasm, he nodded in satisfaction. Pulling out his penis he observed as the filled liquid spurted from her insides and drenched the bed.

"Guess Frederica is going to have to clean this, again. Though, well. That would lead to an exciting morning…" As Subaru's brain was being filled with lustful thoughts, he did not notice the movement of his current partner. Before he knew it, it was him who was flipped towards the bed.

Laying on his back, he noticed the figure towards his lower body. Needless to say, it was Ram. Without a word she grabbed his penis tightly. And in one fluid motion, she engulfed the entire thing in her mouth.

His exhausted body part that was in the process of resting, was invigorated once again. And due to his sensitivity, the pleasure that struck his member was intense.

Ram wrapped her tongue around the penis that was resting inside her mouth. And without holding back, she sucked and licked it with intensity. Bobbing her head with intense motion, she kept her eyes on Subaru, who was trembling. Deriving some satisfaction at that, she used both her hands to massage his balls at the same time. She could feel his penis twitching and spasming inside her mouth. She could feel it reach deep inside her throat. But with incredible control and precision, it was her who was in control.

Soon she could tell that his pleasure had reached its limit and that he was about to burst. But then an idea struck inside her as she pulled the dick outside from her mouth.

"R-Ram, what the hell are you planning? I don't like that look in your eyes-" Before he could continue, Ram pointed one hand towards his dick. And then,

"What the–!"

As if lightning had struck him, he felt an intense feeling all around his penis. He felt pleasure reaching every single point of skin on his member. He could feel pressure and a constant feeling of pleasure.

"Don't tell me …..Ram!"

At those desperate words, Ram smirked.

What she had used, was nothing but a careful application of wind magic. She had wrapped a constantly moving wind all around his member. The pressure, the feeling and intensity was just right. And she watched as his penis ejaculated. Yes, Natsuki Subaru had been made to cum due to wind.

The strong ejaculation splattered all over her body, and her partner drowned in his orgasm.

Using her fingertips, she took the semen stuck on her cheeks and licked it clean with her tongue. At that figure of Ram-sama,

"Ah, as expected, I truly Love you, Ram." An unexpected confession struck her like a curveball. She could not help but widen her eyes in embarrassment and turned her face away from him.

"Why don't we just make it official? Marry me already, Ram. Become one of my wives."

Instead of a verbal answer, Ram moved her body. Using her hips, she placed the tip of his penis at the entrance of her pussy. And then slowly and gently, she lowered her hips downwards. Placing her gentle hands on his chest, she began to ride him.

"An Oni's fertility rate is very low.." She spoke softly.

"Hmm?"

"But if I were to, let's say, get pregnant. Then for the dignity of myself and the baby, this Ram-sama would have no choice….I g-guess."

Instantly, Subaru grabbed both her arms and embraced her just like that. Placing his lips next to her ears, he spoke in a quiet whisper, "Guess I'll have to try even harder to do just that."

In response, Ram began to use her hips wildly. With incredible mana and wind manipulation, she quickly reached incredible speeds and dominated her 'Love'.

Thrusting again and again, again and again, she had no intention of stopping.

Looking at that female figure who was riding him with wild ferocity, he smiled at the love which was being transmitted to him.

"With all this intense smacking, both of our legs are going to sore as fuck tommorow."

With such a thought, the sound of their love making continued deeper into the night.

Drowned in nothing but themselves, this intense night was only one of many.

Chapter end.
