The Main Character is the Villain

I pulled down Sieri's pants. Sieri didn't resist the action, which had been repeated for a long time. With her eyes shut tight, she was letting me do as I pleased. Her pants fell to the floor. Her white panties were already getting wet. I rubbed Sieri's center with my finger and asked.

"You're wet already."

"Haa... ha... yes..."

Sieri nodded, absorbed in my touch. I pulled down Sieri's panties as well. She lifted her legs slightly, making it easier for my hands to play. Her lower body now completely naked, she wrapped her arms around my neck, her face flushing red. When I lowered my head without resistance, she pressed her lips against mine.

Once again, our tongues crossed, and saliva flowed between us. Churning and tangling our soft tongues, I pushed her against the wall. Her shoulders touched the wall lightly, and she leaned her head against it. Her lips smelled of the scented candles used in the Archdeity Church.

When I pulled my lips away, Sieri was staring at me, her tongue peeking out slightly. I coveted her lips once more and slowly lowered my hand. She spread her legs as if in expectation of my touch.

"Sieri."

"Yes. My Lord..."

"Do it yourself."

"B-By myself?" Sieri flinched, her voice feigning surprise. She probably hadn't told me, but she must have been enjoying herself alone in her room from time to time. With a twitch of her body, now accustomed to me, she cautiously moved her hand to her private parts.

She was like an imitator copying my actions. She caressed her own thigh with her hand, then slowly stroked her crevice, clenching her teeth.

"Haa..."

Did she think it was shameful to make sounds while pleasuring herself alone? I unfastened my pants and took them off. The moment the garment came off, my large member sprang out as if to overwhelm Sieri. Sieri's expression was full of expectation as she looked at it. I said, stroking my member with my own hand.

"Sieri. Keep going. Keep going..."

"Yes... My Lord..."

"And, call me Lusius. At times like this..."

"L-Lusius..."

I had told her many times in private to call me Lusius, but she still called me My Lord. It seemed some line in her heart was holding her back. Sieri, with her legs slightly parted, began to rub her private parts with her hand.

Parting her pubic hair and caressing her folds with her own hand, the sight was both vulgar and utterly obscene. That pure and cute nun, showing such a vulgar side at my command. I couldn't help but become incredibly aroused watching Sieri.

The pleasure of knowing I was breaking someone. The joy of her doing as I say. All of this was becoming a sweetener for my masturbation. I continued to masturbate, staring straight at Sieri's face. She, too, stared back at me, her eyes half-lidded and her face flushed red.

"Haa... haa... haht... Lusi...us..."

The distance where our breaths could touch. We were breathing in each other's sighs. Sieri's body trembled, but she didn't stop moving her hand. Even though she must have known how vulgar and embarrassing it was to do this while standing, she couldn't stop. Because I had commanded it. Sieri was following my command.

"Lusius... ah... ahh... Lusi...us..."

She was engrossed in self-pleasure, repeatedly calling my name. It seemed my name was the main source of her pleasure. Drip, drip. Obscene fluid was falling to the floor. The vaginal fluid that trickled down Sieri's thigh formed droplets on the floor. She finally stopped leaning straight against the wall and began to lean on me.

"Ahh... ahht... ahhhh..."

Her hand movements were unrestrained and so very rough. But even those clumsy movements seemed enough to lead her to pleasure. The glans of my penis brushed lightly against her thigh or pubic hair. I quickened my hand movements, soaking in the pleasure. She and I were both out of our minds. We were unleashing our own pleasure while leaning against each other.

"Aheuuuuuuht...!"

It was Sieri who reached orgasm first. Her legs trembling, she hugged me tightly. And at the same time, I ejaculated forcefully. Startled by my ejaculation, Sieri flinched. My semen, which had stained her pubic hair and thighs white, was trickling down her leg and falling to the floor again.

"Haa... haa... Lusius... Lusius..."

She kept calling my name as if it had become a synonym for salvation. I pushed her against the wall again. Swept up in pleasure and having lost her will, she went limp in my arms.

"Sieri. Today, you will become completely mine. Understand?"

"Yehes..."

"Sieri, you must not follow anyone else's words from now on. You must follow mine. Understand?"

Sieri hesitated for a moment. I pressed my leg against Sieri's private parts and licked the nape of her neck. Going limp again, she nodded and replied with a short "Yes." I had Sieri spread her legs a little wider. And I said to Sieri.

"Sieri. Why don't you spread yourself open a little more? With your hand."

I was demanding that Sieri spread her own entrance open. Ashamed by the demand, Sieri shook her head and hesitated for a moment. I whispered into her ear.

"I told you to do as I say. Sieri. You like me, don't you?"

"...Yes..."

Sieri nodded and brought her hand to her genitals. Spreading her own vagina wide, she shut her eyes tightly. She seemed to know just how shameful her action was. I pressed my cock against Sieri's genitals and began to rub slowly. As if that action alone melted her shame into pleasure, Sieri let out a moan with her eyes closed.

"Ahm... ah... ahht..."

"I love you, Sieri."

With those words, I pushed my hips in all the way. I could feel Sieri's vagina, developed over a long time, accepting my cock. I could feel her vaginal walls, soft but still not used to a man, gauging my member and expanding themselves to their limit. Sieri stood on her tiptoes, gripped my shoulders tightly, and contorted her face. I caressed Sieri's buttocks as I kissed her.

"Haeu... ah... ahh..."

She let out a pained moan and leaned against me. Was it still too much for her to feel pleasure from my member? She was barely standing, her legs trembling. I bent my waist slightly, deciding to give Sieri some space. Feeling the huge member that had invaded her body pull out, she regained her stability.

"Haa... haa... Lusius... it's... it's too... big..."

"You'll get used to it, Sieri. Think about it. It didn't feel that good when you first put your fingers in, did it? But now it feels good. What do you think will happen once you get used to this thing?"

At those words, Sieri's face was awash with fear and expectation. The fear of whether she could accept such a thing. And the expectation of the pleasure that would come at the end of accepting it. She was getting excited. And she was surprised at this side of herself. I whispered.

"Accept it, Sieri. This is who you've always been."

I slowly began to move my hips. Each time I thrust my hips upward, Sieri's body trembled and reacted as if she were hiccuping. She shook her head, confused by the pain and the blooming pleasure.

"I'm not... No... euht.. I, I'm..."

"Then what kind of person are you, Sieri? Who was it that came looking for comfort today?"

"Heung... that was... me, but... ahht... ahh... aheu... that's..."

"Sieri. You're looking forward to what will happen once you get used to this, aren't you?"

"Ahht... that's... th... that's...! Haang... a-eung..!"

As Sieri's body grew accustomed to my cock, she began to feel pleasure. Savoring the inside of her vagina, I forcibly held back the explosive feeling of ejaculation and continued to move my hips. Not overdoing it, slowly enough for her to melt into the pleasure of the movement.

"Sieri, you're a truly lewd person. Aren't you."

"I'm... not... I'm a... of the Archdeity Church... heung..."

"Having sex like this with a high priest of the Archdeity Church."

"I... something like this..."

"You actually know, don't you? That you shouldn't be doing things like this with a man who's about to be married."

"Ha-eung... th-that's why... I... ahht... heung... eueung..."

"Sieri, you're a very vulgar person. You're defying the teachings of the Archdeity Church and also having an affair with its high priest."

"Eueung... ang... aang... I don't know... I don't know... Lusius... I don't know..."

"Sieri, I'm the only one who can save you from this. Only I can accept your sins and take you in. Isn't that right?"

"Eueung... aang... I don't know... ah... ahht... I don't know... Lusius... I'm scared... heung..."

"What are you afraid of? The sin to come? Or yourself, for getting excited in this situation?"

"Aang... ang... that's... heung... eueung... a-eung..."

"Everyone will despise you. They'll condemn you as a prostitute and strip you of your position as a nun. They'll denounce our morality, saying we had sex behind the Lady's back without you even being an official concubine."

"No... I don't want that... a-eung... heu-eung..."

"Then what should you do? I'll have to take you in. Sieri... you'll become my concubine, won't you?"

"Yes... a-eung... heu-eung... ah... ahht..."

I asked, gradually quickening my back-and-forth movements. Sieri was melting from the pleasure I was giving her. She could only let out moans while gripping my shoulders. I continued to whisper in Sieri's ear.

"I will absolve you of your sins, Sieri. You've committed too great a sin to remain a nun."

"That's... a-eung... I don't want..."

"But you had an affair, didn't you? Who is going to forgive your sins?"

"That's... that's Lusius... you... heu-eung..."

"That's right. I will absolve you of your sins. I will forgive your sins and let you be under me. So, Sieri."

I thrust my hips up with all my might. At the peak of pleasure, my cock began to gush out semen. Sieri didn't know what to do with herself, overwhelmed by the pleasure dominating her lower body. For her, a pleasure like this must have been a first. She was buried her face in my shoulder, panting.

"Obey my words."

"Yehes..."

Sieri nodded, leaning against my body. Now I had to worry about whether Eve would tolerate polygyny. Mermaids don't get married, and this country allows polygamy, so wouldn't she permit it?

Between the knee and the scales. In the either-or choice of sexual desire, I decided to choose both.
