The Main Character is the Villain

"Is this all that medicine?"

"Yes. It is."

A few hours later, Robin returned with his soldiers, pulling a cart piled high with boxes. A single glance told me there were enough medicine boxes packed inside to stock an entire store. I opened one of the boxes and examined its contents.

[Lowest-Grade Aphrodisiac]

Increases sensitivity during sexual intercourse.

Due to its low quality, its effect diminishes and spoils after being opened.

Though it was an aphrodisiac, it didn't seem to have any harmful effects for now. Taking advantage of the moment while Robin was giving orders to his soldiers, I swiped about three bottles from the already opened box. Then I casually closed the lid and spoke to Robin.

"Robin, I will write a letter, so please send these boxes via the Royal Palace mail. And thank you for your hard work."

"N-Not at all, My Lord. I could not have accomplished this without your insight."

Robin was being modest, flattering me. I decided to graciously accept his compliments and went up to my office. Aira was waiting there. As soon as I entered, she threw her arms around me and spoke. "My Lord! I missed you so much! That representative was so boring... and scary..."

"Scary?"

"Yes. He never spoke to me, and when I asked if there was anything for me to do, he just told me to rest... It was scary."

From the sound of it, he was the ideal superior, so I had no idea what she found so scary. It wasn't like Karin had taken Aira along to hunt down and crush criminals. Was this the same logic as a dog pissing itself when it sees a dog catcher? Did Aira, a swindler, instinctively fear Karin?

"I see. That must have been difficult for you."

I looked at Aira for a moment, fondling the aphrodisiac in my pocket. Her reactions during sex were already intense, so there was no need to use something like an aphrodisiac on her. I sat down at my office desk, wrote the letter to be sent to the Royal Palace, then patted Aira on the head and went back down.

After giving the letter to Robin, I went back up to the bathhouse. This time, I took off my clothes, grabbed one of the aphrodisiacs, and entered. Cellu was soaking in the bathtub, humming. She grinned when she saw me come in.

"Heh... What's this? Did you really come to fuck a mermaid?"

To be honest, ever since I first heard about mermaids, I'd been curious if I could have sex with one. First, their lower body was a fish. Second, they lived their entire lives in the water, so there was almost no chance to meet one. And third, as a cleric, I couldn't purchase something like a mermaid slave.

But now that a highest-grade mermaid had practically fallen into my lap, I was planning to give it a try. Just like a mermaid from an erotic game fantasy, Cellu was properly equipped with genitals. A mermaid's body was human down to the genitals, with a fish tail attached below that. It was as if her thighs had fused together to become a fish tail.

Her face was quite pretty, and her red hair clinging to her chest gave off a seductive atmosphere. The thought of pinning down and fucking this bitch already sent strength to my lower body. Seeing my 'thing' grow, Cellu crawled out of the bathtub with a look of fascination.

"Heh... It's huge. This is the first time I've seen one get so big."

"You've seen... Ah, you must have seen many."

Come to think of it, these bitches were the bastards who went around performing castration on a man's 'thing'. Her words, that mine was the biggest she had ever seen, somehow felt deeply unsettling. Cellu was lying slightly prone on the floor, looking up at me. I lightly stroked my 'thingamajig' and asked.

"Will you be okay?"

"It's fine. I lost the fight anyway, you saved me when I was about to be preserved while alive, you spared my daughter even though she's tied up, and you gave me this bathtub. Honestly, you're the kindest human I've ever met. And to be honest, I was curious what it would be like with a human."

"By the way, how do mermaids reproduce?"

Now that she mentioned it, I had never seen a male mermaid. Male mermaids didn't appear in the game, nor did they seem to exist in this worldview. Cellu shrugged and said.

"By laying eggs."

"You lay eggs?"

"During our fertile period, we store nutrients to make eggs. But, are we just going to talk about boring stuff like this? Hm? I'm a bit more interested in this here..."

Cellu opened her mouth and flicked her tongue around my cock. Her sharp teeth were exposed, so I grabbed her face and gently pushed her back.

"Wae-euhe?"

With my hand pressing firmly on her cheek, Cellu looked at me with a dissatisfied expression. I pulled my hips back slightly and said.

"No, but putting it inside those teeth is a bit..."

"Ah, ahh..."

Cellu ran her tongue over her teeth and nodded. Since these bitches usually tore apart and ate raw seafood, their teeth were unbelievably sharp. If I put it in there and Cellu decided to bite down, my sausage would be torn to shreds like scrambled eggs.

"As long as I don't put it in my mouth, it's fine. Right?"

Cellu pushed my hand away and grabbed my cock again. The cold, soft touch of her hand made me let out a strange moan unconsciously. Perhaps because she was a mermaid, Cellu's tongue was quite long and thin. Her tongue wrapped around my glans penis and began to caress me, flicking here and there.

I didn't have the composure to just stand still and receive her foreplay. Her technique was incredible, as if she'd been practicing this sort of thing every day with a dildo. I took small steps until I was sitting on the edge of the bathtub. As I lowered myself, Cellu straightened up and began to slowly rub my cock.

"Sseueup... Hoo..."

I let out a breath and watched Cellu. She grinned slyly and quickened the pace of her hand. The tongue tickling the tip of my glans was constantly intensifying my ejaculatory desire.

After stroking my glans with her tongue for a long time, Cellu gently parted the tip of the glans and pushed her tongue inside.

"Aheuk!"

In that moment, as if in an explosion, semen erupted from me, and I bent over. Cellu licked the semen that had splattered on her face and looked at me. Her grinning expression seemed to be mocking me.

"Heh..."

I grabbed Cellu by the shoulders, lifted her effortlessly, and entered the bathhouse with her. Cellu surrendered her body to me, floating gently in the bathwater. I fondled the smooth, scaly part of her before grabbing the aphrodisiac I had left outside. Seeing the bottle, Cellu reached out and examined it.

"What's this?"

"An aphrodisiac. I caught those aphrodisiac-collecting criminals, and I brought one back from their stash."

"Heh... This kind of stuff doesn't work on mermaids. I told you. Mermaid blood has an aphrodisiac component."

Saying that, Cellu opened the aphrodisiac bottle and downed it in one go. She then scrunched up her face and complained that it tasted bad.

"It tastes weird."

"Are you really not feeling anything?"

"Not really? It must be really weak. Still, I guess I feel a little flushed or something."

I kneaded Cellu's breasts while continuing to ask about the efficacy of the medicine. She seemed unimpressed even when I carefully fondled her nipples. The medicine had little effect. Caressing her breasts had no effect. Unexpectedly, the mermaid seemed to be the type who wasn't much fun during sex.

"Are you just going to keep doing boring stuff like this? If kneading breasts is supposed to be so great, can I just go to sleep?"

Cellu said with a bored expression. And that statement was a blow to my pride. I moved my hand down and found Cellu's private parts. My hand touched her smooth private parts, and I parted the crevice and thrust my fingers inside in one motion.

Since she was a bitch who masturbated with a dildo every day, I figured it wouldn't matter if I stuck a few fingers in her at any time.

"Eueung..."

Startled by the fingers that had opened her crevice and entered, Cellu flinched before closing her eyes and rubbing her body against me. The moist skin texture gave a novel sensation. Every time I moved my fingers, Cellu's body shook with a splashing sound.

"Heheung... Haeu... Heueut... Good... Heu... Yes... Doing this... is... Haeu..."

As if completely absorbed in my foreplay, Cellu clung to me tightly. The inside of Cellu's crevice was soft yet surprisingly tight. After confirming that I could fit up to 3 fingers inside without any trouble, I pulled my fingers out, grabbed Cellu's waist, and lifted her.

"Aheu...?"

Just as Cellu showed a bit of surprise at being lifted so suddenly, I aligned my magnificently large cock with her crevice. Cellu looked at me, her face full of a sense of expectation. She let out a heated breath and wrapped her arms around my neck. At the same time, I pierced through Cellu's crevice.

"Haeu... Haeueut...!"

Cellu's tail thrashed. Watching the water splash violently, I was reminded of fish for sashimi at a live fish market. The tactile sensation inside Cellu was good, but separate from that, the way her tail flapped every time I moved my hips was really distracting.

Fuck, are there really bastards who enjoy this kind of sex? Is it the part where they cut off the tail and eat it as sashimi after sex that's so good? Grabbing the part I presumed to be Cellu's buttocks, I began to move my hips rapidly. Cellu clung to me, continuously letting out rough moaning sounds.

"Heh... Ha... Hah... Ueut... Ah... Aaat... Good... So good..."

The bathwater sloshed with every thrust of our hips. Her flapping tail splashed water onto my face. Cellu licked my face and grinned with a dazed expression. As if mesmerized by her smile, I moved my hips frantically.

It was as if I had become a pump drawing water. Cellu's inside clung tenaciously to my 'thing' while smoothly aiding the back-and-forth movement. It squeezed tightly, yet it was wide and deep enough to accept my cock.

Except for the subtle fishy smell during sex and having to watch her fish tail flap around, she could be called a pretty excellent sex partner. Of course, those first two things were significant minuses.

"Haa... Heueu... Good... So good... Heuheueut... Ha... Aah..."

Cellu's face turned bright red as she buried it in my chest. I, too, was reaching my limit and put more fervor into my piston-like movement. My hips moved faster and faster, and Cellu gripped my shoulders tightly, gasping in ecstasy.

"Heueueueueut!!! Heuheureuk..."

As my cock forcefully spewed out semen, Cellu's body trembled, her back arching like a bow, before her head plunged into the water. Cellu floated limply like a drowned corpse, and semen flowed out from her private parts, dirtying the water. I put the limp Cellu back into her original bathtub and drained the bathwater.

Having to drain the bathwater after having sex once was a fucking pain in the ass for cleanup. The pleasure was significant, though. Cellu said, her body draped limply in the bathtub.

"...The best. That was the best I've ever had... Heh..."

"Same here, Cellu."

I patted Cellu's head and went outside. As I was getting dressed, something tickled my leg, and I looked down at my thigh. A few scales were stuck to it.

"Son of a bitch."

It seemed monster girl sex was still a bit too advanced for me.
