Sharky was kissing her, fiercely and passionately and messily, carelessly nicking her lips with her sharp teeth. She licked the blood from them with a ferocious hunger, sucking Isla's lips until they were puffy, before she sent a pulse of healing magic through her and sealed the cuts. Her bruising, grazing kisses moved down Isla's jaw, down her neck, as her hands tugged the human hard against her cold body, her prehensile cock writhing between Isla's thighs. Isla pressed her legs together tight and moaned as the mermaid bucked her hips, the member sliding hard and fast against her clit, too impatient to wait to be inside her.
The entwined creatures, human and mermaid, sunk through the water into the seaweed forest on the sea floor. Above them, the sunlight glittered through the rippling water, distorted in the currents, and dolphins swam and played with each other, forgotten by the two who were engrossed in only each other. Belle was Isla's great love, but Sharky was something else entirely. She was terrifying, unpredictable, thrilling, and Isla knew to expect pain along with the pleasure, but she also knew every bit would be worth it.
Sharky sunk her teeth into Isla's neck and Isla cried out, shuddering as the sharp pain radiated through her body, but it soon dulled to a gentle throbbing as Sharky healed the worst of the damage and licked her teeth, excited by the blood she had been allowed to taste. She reached out to grab handfuls of seaweed, and pushed Isla's hands above her head, tying her wrists together. Holding her down, she grinned down at the human, trailing her nails down Isla's naked body, goosebumps following in their wake.
"I can't do this with my friends," Sharky murmured, her fingers finding Isla's pussy and pressing inside, making the human arch her back with a moan. "Humans are good."
"Better than dolphins?" Isla teased breathlessly, panting as her hips bucked against the mermaid's fingers.
"Maybe," the mermaid replied simply, before grabbing Isla by the hips and flipping her over. Isla sunk into the seaweed and sand, her bound hands stretched out in front of her, her ass in the air, presented lewdly for Sharky's pleasure. Sharky wasted no time in sliding her tentacle inside Isla, stretching her pussy with its thick ridges, tight against her slick walls as she started to thrust. Isla groaned in delight, the burning heat of the pleasure inside her making her toes curl. Oh, Sharky was good. She'd learned some tricks in the time they'd spent together. Isla was sure she'd never feel anything quite like her from anyone else.
Sharky fucked her, and fucked her good. Her thrusts were rough and hard and her hands left prints on Isla's hips and scratches down her back. Isla was helpless, tied and used but loving every second of it, filled by thick mermaid cock that hit deep inside and made her gasp and cry out in pleasure.
Sharky groaned, growled, snarled as she worked her hips hard against Isla's ass, sending the human into one orgasm and continuing on, building her up to another. Isla writhed and rocked and squirmed under her, burying her face in the sand, and finally letting out a scream of delight as Sharky fucked her into another orgasm. Her body shook and her pussy clenched and finally Sharky tipped over with her, groaning loud and digging her claws into her hips as she filled her with cum.
When Sharky pulled out and floated down to the sand, laying next to her with a satisfied, toothy grin, Isla flopped next to her, trembling from the intensity of the experience. The mermaid pulled her close, stroking her belly with her claws and sending more magic through her body, so considerate for her human lover despite her ferocity otherwise. While Sharky was a wild creature, untamed and rough, she'd mellowed with Isla's help. They'd spent many a fine day in each other's pleasurable company now, but it seemed that soon it would be coming to an end.
"I am leaving," Sharky blurted out in the comfortable silence. "My friends will swim south. I will go with them."
"Oh, no!" Isla propped herself up on her elbow, dismayed. She'd known this couldn't last forever, but she would miss the mermaid she shared with Belle. "When?"
