(I happened to see KHR mention so I need to take my shot, Superbi Squalo my beloved) Once upon a time, a mermaid sought to best warriors across land and sea. Exchanging your tail and voice for the legs needed to pursue him, you're finally face to face with the Sword Emperor himself. A flurry of blows as you both dance along the tide like frenzied sharks, tensions are high, and bloodlust leads to a more carnal sort. You may not be using those new legs for a while after..... (cowgirl, competitive sex, is this enemies to lovers?)
"Voi--when I'm through with you here, you better guide me to that witch who took your voice and your scales."
Amidst the harsh crash of waves along the rocky shores, the Sword Emperor's voice cut through the noise, his tone as loud as it was taunting.
You could not look back to him nor answer him--Squalo. That right was lost to you, as signified by your broken blade that was strewn across the shoreline where the two of you clashed.
Not to mention that you were currently positioned on all fours upon the sand before him as further demonstration of your defeat, kept anchored in place by the iron-clad grip of his hands on your hips.
"Still undecided between making her give you back your tail or--"
Dark laughter broke free from his lips.
"--have her make me just like you, sirena."
At this, your head flew back towards him in surprise, your expression shocked.
You were just met by a look of sheer domineering arrogance, befitting his title of Emperor. Even as blood continued to trickle from the cut your blade managed to leave upon his cheek, he was as prideful as ever as he licked his lips just before snapping his hips right against your bared backside, tearing a silent cry of pleasure from your throat.
Continuing to savor his victory over you, Squalo pressed on with ravaging you further, drilling his cock further into your drooling core with not a thought of mercy in mind. As he watched your body tremble, your arms buckling as you did your best to remain upright, he only smirked as he went on with,
"Clumsy as you are on land, you successfully struck me regardless."
His left hand relinquished its hold on your hip to instead reach for your hair, tugging back at your locks as his lips met your ear with the wicked whisper of, "You better not disappoint me when I take the fight down to your depths, sirena. Indulge me in a swimming race too while you're at it."
Feeling your walls clamp down on his cock upon hearing his words only made his smirk widen.
That witch better give him some shark fins.
You already went so far to meet him by land. It was only right that he chase you down to the very depths of the ocean.
