“Ah…!”

Though she tried to pull her hand away in surprise, she couldn’t escape due to the large hand pressing down on the back of her hand. He moved his hand slowly while keeping it overlapped with Livia’s.

“What are you doing now…!”

“I told you to look properly.”

He commanded in a roughened voice that sounded like a growl. Simultaneously, Livia’s hand, caught in Triton’s grip, stroked up and down the pillar she was made to grasp. The thick thing that her hand could barely hold half of twitched and grew taut under her touch.

A soft moan escaped Triton’s lips. The sight was so obscene and erotic that she had to forcefully suppress her gaze from constantly trying to drift to his face. Just then, her eyes caught sight of a strange change in the very place Triton had told her not to look away from.

Why is it doing that…?

The skin underneath was red. Not just flushed from heat, but red as if a heart was burning with light under the thin membrane of skin. It was an unsettling sight. She was certain it had something to do with what he had called his weakness. At that moment, Livia brought her free hand to where the light was emanating.

As soon as Livia’s touch landed, Triton moaned and whispered.

“…A merman’s pleasure becomes his weakness. When the heart grows hot.”

It was just as he said. It was hot. Really hot.

Though he was a man whose entire body was cold like a cold-blooded beast, this place alone radiated heat. When her trembling hand caressed over his heart, Triton exhaled roughly, his throat rumbling like a beast.

“When it turns bright red as if it’s about to burst… That’s when you strike, Livia.”

Though she had asked for his weakness, she never imagined it would be something like this. While observing him with disbelieving eyes, Livia gently pressed her fingertip against where the red light showed near his heart. He smiled, gripping her hand as he whispered.

“That doesn’t mean you can burst it with just one finger though.”

“…”

“And this level of pleasure isn’t nearly enough.”

She felt Triton increase the pressure on her hand that he had been holding loosely. While maintaining eye contact with Livia, he stirred up excitement by moving that smooth pillar-like thing up and down. The more his aroused member responded and twitched, the more vivid the red light near his heart became.

“So, Livia.”

He whispered, drawing her gaze from his reddened heart back to himself.

“If you want to break my heart, you’ll have to drown me in pleasure…”

She could feel his thing pulsing and expanding in her palm. In that state, he slowly tilted his head to whisper in her ear.

“…Can you do it?”

His voice was sweet enough to startle her every time she heard it. The hair on her arms stood up. To make such an irresistible proposal with such a sweet voice.

How could she refuse?

Glaring at him, Livia curved her wet eyes into a smile. Her first smile directed at Triton was rather fierce.

“When a god himself reveals his weakness, and even gets his c*ck hard for this primitive and lowly human, what reason do I have not to take the challenge?”

Livia roughly stripped off her wet, clinging clothes, tearing them away.

Whether you kill me or I harm you, this was a trial that could only end with one of us inevitably destroyed.

Hadn’t she sworn she would spread her legs even for the devil if it meant avenging her murdered family? Livia hadn’t forgotten that yet.

Looking at Livia through narrowed eyes, he suddenly let out a light laugh. It was a smile reminiscent of the calm before a storm.

“Indeed, how brave.”

“…You flatter me.”

“Then willingly devour it.”

As Triton moved his body, the once-still spring water crashed over their entangled bodies like a tidal wave. Livia squeezed her eyes shut and willingly spread her legs to the raging waves.

***

Triton sank his teeth into the slender neck that was letting out ragged breaths.

When he left teeth marks on the slim, clean neck, deeper furrows formed along the already elongated neckline that was straining with heavy breaths. He licked it with his tongue as he moved his body downward.

The br*asts he had just been sucking and biting through wet fabric now lay exposed, tempting him. Despite her being thin, they were quite full and round, enticingly plump. He cupped them with both hands, slowly savoring them with his tongue and teeth as if tasting them.

“Ahh…!”

Livia’s warm flesh melted in Triton’s mouth. When he couldn’t resist and took a large bite of the supple flesh, a wet moan burst forth. He ran his tongue along the n*pple that had hardened to a point in surprise. Harsh breaths escaped from Livia’s mouth, which she was covering with the back of her hand.

“…Hnn.”

He didn’t like either the mouth belatedly trying to stifle moans or the tightly clenched teeth. Did she think she could draw pleasure from him with such a passive attitude?

Damn it all, she was right though….

Triton sneered at himself as he suddenly bit down on the deep pink n*pple.

“Ah!”

The cry-like moan was pleasant to hear. He kneaded her warm br*asts with both hands while tasting them as he pleased. Beneath the trembling br*asts, her rapidly breathing ribcage looked fragile.

Need to fatten her up.

Triton thought absently as he traced the protruding bone contours with his fingertips, not realizing how much more it made Livia’s skin crawl. She looked down at him with wary eyes, startled.

But her eyes were already wet and feverish with *rousal. Triton maintained eye contact as he casually sucked her br*ast. His hand traveled down her squirming waistline and grabbed her plump b*ttocks. And when he slowly slipped his fingertips between her spread b*ttocks, Livia frantically grabbed his shoulders.

“Hnng…! J-just, hurry…!”

“Inexperienced, I see.”

“…!”

“Looking at you, you seem to think it’s just about sticking it in and coming.”

Foolish and innocent Livia.

Triton licked Livia’s cheek and whispered against her reddened earlobe.

“Just f*cking and coming won’t get you my heart, Livia.”

Livia’s movements stopped. He could see her suppressing that remarkable temperament of hers that usually showed its claws at any provocation. While admirable…

“You’ll have to try harder.”

That wouldn’t be nearly enough.

When he inserted his fingers between her plump folds, her soaking wet hole twitched and nibbled at his fingers. He felt a w*tness different in consistency and temperature from the spring water. The tight hole pushed against his fingers, but Triton paid it no mind and pushed in deeper.

“Ah, ngh…!”

Livia, who had been letting out moans, opened her eyes wid, feeling uncomfortable. She had bitten her lip so hard it was bleeding.

Triton’s sensitive nose caught the scent of Livia’s blood. The raw scent this woman could produce. His mouth watered. A hunger resembling lust tightened his stomach. Just as his tongue was about to lick his lips, Livia, who had been moaning with a deeply furrowed brow, grabbed Triton’s cheek.

Just as he thought her humiliation-filled gaze was drawing closer, he tasted blood. A shiver ran through his body as if scales were sprouting all over. He felt her mouth, which had only known how to bite when invaded, now sucking deeply on his tongue. Just from that little thing, heat rose throughout Triton’s body.

The smoldering heat in his heart burst into flames.

Livia, who had drawn his tongue into her mouth, nibbled on it clumsily. She touched his teeth with her tongue tip, and lifted her hips that had been sitting on his center to rub her s*x against him. The soft flesh of her inner thighs pretended to swallow his sharply risen member, inexpertly but eagerly.

Ah, Livia.

Curses rose in his mind as his vision turned red. The violent shark instinct he had kept surged up.

Triton lifted Livia out of the splashing water as if pulling her up by the roots, and laid her down outside the spring. While devouring the lips of Livia, who had frozen in surprise at the sudden change, he burrowed between her legs.

Though he wanted to thrust in right away, he gritted his teeth and held back.

Generally, a merman’s member was longer and thicker than a human male’s g*nitalia. Moreover, a shark tribe’s s*x organ differed in both shape and function from ordinary ones, so putting it in raw would destroy her womb.
