Sins Paradise: Domination System

"Yes," Emilia replied to her. "Comforting Arthur, after he returned from a fight, is my duty as her woman." She smiled softly with a hint of lust in her eyes. "You will understand after you watch us."

"Or you can leave if you're uncomfortable with it, Eliza," I added as I walked toward Emilia. The lewd teacher began to pull her panties down, revealing her wet pink slit that was waiting for me in anticipation.

Eliza's eyes followed me as I sat on the bed beside Emilia, putting my arm over her shoulder and squeezing her breast.

"Ahn~ Arthur~" Emilia's voice turned sensual when I pinched her nipple, sending pleasure to her body.

"So do you want to stay and learn how to do it with me, or do you want to leave the room?" I asked once again, looking at Eliza. My hand slowly went down Emilia's body, caressing her thighs as it slowly went to the inner section.

As a gullible person and a tsundere, Eliza would deny that she didn't want to watch but still choose to stay. In fact, she looked with anticipation as my hand slowly brushed against Emilia's entrance.

"Hnn~!" The perverted teacher moaned loudly as her body shivered from pleasure. "Haa… S-Student Eliza, hnn~ T-This is just a lesson. B-But I will allow you to skip the class if you don't want to watchh~!"

Her last sentence stretched as I flicked her clit, playing it around. This was one of Emilia's weak spots. Her voice became incoherent, and she solely focused on pleasure now.

So I asked Eliza on her behalf.

"What do you want to do, Eliza? Because I am sure that I can't really hold myself now after I have a rush of adrenaline from dealing with Duke Bluerose earlier."

"I…" Eliza sounded hesitant as she covered her face with her hands. But there were gaps between her fingers, and she peeked through them.

Meanwhile, I kept playing with Emilia with more intense skinship. I leaned closer to the perverted teacher, kissing her neck and slowly going for a kiss. Emilia had been waiting in anticipation with stretched tongue, wanting me to suck on it, and had a sloppy, deep kiss.

It was just before my lips touched Emilia's that Eliza raised her voice.

"I-I will stay. I want to stay with Arthur! I love him! So I will stay and learn how to help him! P-Please let me stay!"

I stopped and looked at her, grinning. Another requirement was finished.

'Just as I expected.'

Having max favorability meant the heroine wouldn't hate MC just by finding he had another girl. And I was the main character here in Eliza's eyes. And probably, Emilia had explained to her that my 'business' earlier was to settle the engagement thing with Duke Bluerose.

That was why the perverted teacher prepared Eliza and taught her some techniques to further make her less innocent and open-minded about sex. I owed Emilia one, it seems.

"Well, Arthur. Now that Eliza has given her answer, may I get my reward? Let me be on top for now and teach her how to do it as her teacher."

Emilia had the most perverted expression on her face. She crawled on my lap and kissed me deeply while raising her ass, prompting me to hold and fondle them. I did, and my finger spread her pussy wide, causing the perverted teacher to moan once again.

"Hnn! D-Did you see it, student Eliza? This is where Arthur's penis, or cock, will enter me. It's the hole where a lot of love will be made. As you can see, I am already wet because I am so excited to make love with my master, Arthur. Now, just watch as we do it. I might not be able to explain it to you."

"Y-Yes." Eliza nodded obediently with a red face. Her hands were put above her thighs as she fidgeted nervously.

"Fufufu, she's cute. I know why you like her, Arthur." Emilia turned to me and whispered close to my ear. "Now, shall I take the lead this time? Just lay on your back and enjoy it."

"I will," I replied as I lay down on the bed, watching Emilia free my erect cock from my pants.

After that, Emilia rode me as I laid on my back, looking at Eliza, who sat on the bed next to us. I could see the look of pure lust on her face, which made me smile.

The perverted teacher then reached out to touch her breast with one of her hands. With an embarrassed expression, Eliza watched intently as Emilia slowly moved down, using her hand to guide my cock to enter her wet slit.

With a soft sigh, Emilia's pink pussy welcomed my dick inside, making me groan in relief.

"Aaah!" A lewd, pleasured moan escaped her lips. "Mmm~"

Eliza bit her lip and watched our bodies closely, feeling aroused herself.

"I will start moving, Arthur."

Emilia used her other hand to tease her nipple, slowly moving her hip up and down my shaft with slow thrusts. Inside her pussy was warm and tight but also very slippery, allowing her to move freely without worrying about friction. The sensation was amazing; it felt great.

And seeing the way she moves her body, I knew what kind of pleasure Emilia would give me. It was really amazing. Her pussy was really compatible with me, giving me more pleasure than 20 Succubi combined earlier.

To be honest, letting her have a lead like this wasn't bad at all. My hands were behind my head as I looked at her swaying hips, enjoying every second of it.

"Hnn~ Ah! It feels good. I love this!"

Her breasts swayed, too, bouncing slightly with each movement. Seeing her big tits bounce around, combined with the sight of her pink pussy sliding along my dick, made me feel really excited. The dress she pushed away made her look more erotic.

The pleasure she gained from my cock sliding inside her pussy and touching her cervix must've been too much, as her face became a mess from saliva that dripped down her sticking tongue.

At the same time, I could hear Eliza moaning quietly beside us. Hearing her voice only added fuel to my arousal. I looked to the side and saw my childhood friend rubbing her thighs together with a rough breath.

'Look at her. She's aroused too, seeing me having sex with Emilia.'

"Ah... Mmph! Uwahhh..."

She seemed to be getting closer to orgasm, judging by her moans. I couldn't help but stare at those large boobs as they bounced around. Emilia's eyes met mine briefly before returning back to focus on fucking me.

Soon enough, the moment arrived when Emilia started cumming.

"Nngh! Nngh! Hnn! Yeeeessss! Cumming!"

She moved her hips up as she quivered and shot love juices on my cock. At the same time, her mouth opened widely, sticking her tongue out.

"Huh?!" Eliza, who was watching, looked surprised.

"Is this your first time seeing a woman squirting?" I asked with a teasing tone. The brown-haired girl nodded stiffly, her eyes were planted on my now wet cock. "Then I will show you how I shoot my semen to impregnate Emilia."

All I cared about right now was how much I wanted to fill Emilia's pussy with my seed. And that meant I needed to keep going.

So, I held Emilia's hips and pushed her down once again.

"W-Wait– Oooh!" Emilia cried out, startled.

But she soon recovered, grabbing onto my stomach for support. After that, we continued moving our hips, building momentum. She grinded against me hard, causing me to grunt loudly.

"Haah... Haahahaha!" I laughed happily, pushing myself deeper into Emilia.

She also moaned, biting her lower lip as she moved on top of me. My hands which supported her hips caused her to move even faster, swaying and grinding her ass. Her pussy kept squeezing my dick, sending waves of pleasure throughout my entire body.

"Aah! I am about to cum again, Arthur!"

It didn't take long until Emilia climaxed yet again, shooting hot liquid over my shaft and balls. This time though, there was so much of it, splashing across my groin and dripping off of my belly.

The sex smell filled the air and sent shivers through my spine, making me shudder. But that wasn't the best part. Because I also got to watch Eliza begin to touch herself on the side. Her honest gaze was fixed on me as she masturbated, her fingers rubbing her clit through her panties.

That was when I noticed that Eliza's left leg had fallen open, revealing her wet panties. She slowly fell into the dark side.

I grinned, and so was Emilia, who kept moving on top of me.

"Aahn! Ehehee! Aaaahh~!"

As she came down from her orgasmic high, Emilia slowed her movements and leaned forward. She placed both of her arms on either side of my chest and stared into my eyes, her cheeks flushed red.

When she felt I was about to cum, she moved faster once again, grinding her ass against my pelvis and moving back and forth. The Lewd sound of the round ass hitting me echoed in the whole room.

"Give me! Shoot your seed inside!"

My cock throbbed within her pussy, ready to explode any moment. I gripped Emilia's waist tightly and thrust upwards, burying my full length deep into her warm tunnel.

"Mmmfph!" Emilia let out a cute moan as I penetrated her deeply.

Our bodies shook violently, and I felt my cock twitch repeatedly. With every pump, another rope of white fluid gushed forth, filling Emilia's womb.

After several seconds, Emilia fell limp on top of me, panting heavily.

We stayed like that for some time, neither one of us wanting to pull apart. But then, I heard a voice from the side.

"Haa... T-That! D-Did you let it out inside her?!" It was Eliza, looking shocked and confused.

"As I said." I grinned at her while pushing Emilia up. She groaned lightly as she rolled off of me, still lying next to me with a blissful smile. "I will show you how I shoot my semen inside her."
