Sins Paradise: Domination System-Chapter 75: Having my way with my Sister (R-18)

The reason why Rania became a masochist was that the young me bullied her. And she still loved me even though I was like that? A real definition of a masochist, indeed.

Rania looked so sexy that I wanted to push her down. Rather, what stopped me from doing so?

"Alright, I will take responsibility. Live for me, Rania. Become my Vice-Captain, and I will give you what you need."

"Y-Yes, hit me more! They have seen me already. They have seen the real me, so it doesn't matter! Punish me more, Arthur!" Rania pleaded, and I nodded at her wish.

But before that…

"Say that you surrender, Rania. Say that I won the duel. Then, I will give you what you want right here and right now."

She nodded, "I-I surrender."

"The duel is over! The winner is Sir Arthur Vainglory!" Sophia announced, her face slightly red. "And everyone, I order you to leave right now! No one is allowed to enter the training ground!" She commanded the other female knights, and they replied at once.

"Y-Yes!"

I nodded gratefully at Sophia as she flashed a smile at me. Her lips moved slightly, mouthing some words, "Good job!"

The training ground was devoid of people in less than a minute, and I looked at Rania with a feral grin as my right hand rested on her butt, squeezing the red bum and inviting a soft moan from her mouth.

"Hnn! T-That sting a bit. It feels good~"

The dignified knight had turned into a masochistic sow.

"You are really enjoying this, aren't you?" I asked teasingly.

Her cheeks were flushed pink, and she answered shyly, "It hurts, but it also feels nice... Hmmm..."

Sophia walked up behind us, observing our actions. Unlike the other, she didn't leave and stayed on the side with a knowing smile.

I ignored her and turned to Rania. My eyes lingered on her breasts which swayed gently due to her movement, then trailed down her flat stomach until reaching her thighs.

Rania's gaze followed mine, and when she saw how I stared at her, her cheeks blushed dark red again. But unlike earlier, her embarrassment only made her look sexier instead.

"...What do you want, Arthur?"

"I will punish you," I replied without hesitation.

A sadistic smirk formed on her lips, "...Very well."

As if responding to my command, Rania raised her butt at me. My fingers slid under the hem of her skirt and grabbed onto the bottom edge. With a firm pull, I lifted it upwards, exposing her white leotard panties.

"Mmph!" Rania let out a muffled gasp. I smirked at her reaction and pulled down the cloth covering her ass, further revealing more flesh. It was bright red, but I spanked it again.

"Nngh... Ahhh! More!"

I slapped her reddened ass hard enough to make her yelp loudly. When did she become such a slut? Well, I guess that was expected, considering she was a masochist.

After spanking her several times, I slipped my hands underneath her leotard and touched her bare skin. Her ass felt warm and smooth, and I could feel her trembling beneath my touch.

I released her hands which I held behind her, giving her some freedom. She immediately rolled to the ground, raising herself on all fours while spreading her legs open wide.

"Please, Arthur! Spank me harder! Make me your slave! Use me however you please!"

She begged shamelessly, making me chuckle. Punishing my older sister in the public outdoors... This satisfying feeling couldn't be explained.

Then, I decided to test something. I put my finger between her wet folds and slowly pushed it inwards. She groaned loudly, arching her back and pushing her hips toward me.

This time, I kept going deeper, forcing my middle finger deep within her tight hole.

"Ahh... Aaaahhh!! Oooohhhh!!"

Rania screamed loudly, buckling her knees and clenching tightly around my finger. I continued moving it in and out of her, getting used to her insides and adjusting my pace accordingly.

When I reached three inches, I withdrew completely and spanked her.

"Ahhnn!"

She cried out, looking at me pleadingly. I smiled mischievously and rubbed her drenched pussy with my finger again, eliciting another cry from her lips.

Soon after I inserted two fingers inside her, she started moaning louder and squirming against me. At last, I added a third digit into her cunt and began to mess it even harder.

"Ooohhh! Mmmphhhhh!!! Nnnngggggh... Yeeeessss!"

Rania screamed in pleasure, her voice echoing throughout the empty training ground. Her face was flushed bright red, and her blonde hair was disheveled like a wild animal's.

But what caught my attention most was how her boobs shook violently, bouncing about each time my fingers pumped into her. They weren't small either; they were large enough to cover half of her chest, and their shape was very feminine.

The way they jiggled when she moved her torso excited me even more, and I imagined them being stuffed full of cock before shooting off loads of cum.

"Cumming~" Rania panted as I fingered her faster.

"Yes! Cum for me!" I encouraged her.

Rania responded by biting her lower lip, squeezing her inner walls tightly around my fingers, and releasing an ear-splitting scream. Her entire body convulsed, and soon after, her juices gushed forth over my hand, squirting like a fountain.

It was a lot, much more than I thought she would produce, so I took my fingers out of her pussy and spread them apart. Some of the sticky fluid dripped onto her thighs, leaving long trails along her soft skin.

The sight turned me on immensely, and I quickly removed my pants and boxers, freeing my rock-hard erection. I aimed at her exposed slit and placed myself directly above it, rubbing the tip across her entrance.

"Hurry up and put it in already..." Rania pleaded. "Or else I'll die from this torture! Please fuck me like an animal from behind!"

I chuckled, amused by her request. I pressed forward slightly until the head of my dick poked past her opening. Then, I slid it downwards without any resistance whatsoever.

"Ahh!" Rania gasped softly once my shaft disappeared into her pussy. She didn't even care that we were watched by Sophia, who somehow got close to us.

The redhead looked at us intensely with a superior gaze. She might feel good seeing her rival being skewered like this. "Ah... Sir Paladin is really the man. To think the Royal Knight will fall this low..." She muttered with a strange, possessive smile. "As expected of the man that I acknowledge."

Rania's pussy stretched around my cock easily, and I found myself enjoying every second of it. My sister had a nice tight cunt that seemed made just for my size, and I wanted nothing less than to fill her with my seed.

[Ding! You took Rania Reynala's virginity! Your Sins increased by 3!]

I smirked; there wasn't anything but pure bliss between us both.

After a few minutes of slow thrusting, I sped up and pounded away at my older sister. I could feel her insides tightening around me, gripping me tightly and milking me for all I was worth. It felt incredible, and I knew Rania loved it too.

"Nn! Spank me! Harder! Faster!" Rania begged.

So I did, smacking her ass cheeks hard whenever she asked for it. Each smack sent waves of pleasure through her body, making her moan continuously while her breasts bounced wildly.

Sophia was watching from the side. She crouched beside us and began to touch herself. But unlike Rania, she touched her clit instead of her pussy. I couldn't see what happened next because my eyes were glued to the sexy spectacle happening right before me.

"Hnn~ Please do me next, Sir Paladin!" Sophia said.

Her words surprised me, and I paused my thrusting momentarily. "What? Why?"

"I've decided to give myself to you." She answered.

That was unexpected. And yet, I liked the idea.

"Really?" I replied.

"Yeah, why not? Let me join the fun, please. I want you." She added. "If my rival got her virginity taken today, then I will too."

And I couldn't refuse such a beautiful woman. Not only that, this was the perfect opportunity for me to have some fun. I didn't know what she was thinking, but I wouldn't refuse her.

"Arthur... More... Hurt me more! Make me your bitch!" Rania demanded, grinding her hips.

With no hesitation, I slapped her butt again. The sound echoed throughout the surrounding, followed by the squelch of her flesh being hit.

Rania cried out loudly, arching her back and letting loose another orgasmic scream. This time, her voice sounded deeper and louder, making everyone within hearing range turn their heads toward our direction.

"Wait a minute, Rania. I am still talking to Sophia." I reminded her.

"Yes yes, sorry. Go ahead," Rania whispered, panting heavily. "As long as you prioritize this big sister over her!"

I grinned, satisfied that she understood how important this moment was. I grabbed her waist firmly and resumed fucking her faster and harder now. Her tits jiggled each time I slammed into her pussy, which made her nipples stand erect.

At the same time, I looked at Sophia.

"Prepare your pussy, then. I will take your virginity after this."
