Ame gripped violently on Gura's hips, spreading her legs just so, allowing the detective to get a full view of her pussy. She tested with a single finger - as expected, even if her mind was unaware of what was happening, her body was reacting as it should. Which meant Ame had the privilege of getting a taste of Gura "down there".
She dove right in, licking her outer folds, sometimes plunging her tongue as deep as it would go, sometimes circling her little clitty, all the time smelling and tasting Gura's unconscious arousal, tasting vaguely of seafood but not off-putting in the slightest. Tasting Gura's most special place set her own into gear as well; with one hand, she reached down to stroke her own pussy, reaching in with a finger and moaning to herself when it came out shiny slick. She slipped it into Gura's own moistened slit, enjoying the slight contrast in tightness and slickness, spreading her own love juices to mix with hers as she focused her mouth on sucking and nipping at the shark's clitoris. Her other hand wandered freely, cupping Gura's ass, kneading and squeezing, appreciating the powerful musculature of a creature who spent most of her life swimming underwater.
She paused, thinking about toying with Gura's asshole, the tiny, clean pucker just slightly south of her current location. Ah, but wouldn't it be better to fuck her ass with her own strap on? Ame imagined it, stretching the poor hole wide open, not caring about easing it in; Gura was frozen anyway, what need was there to be gentle?
The thought sent another chill down Ame's spine. A bit more play, perhaps. Besides… she had nearly neglected the rest of Gura's body - namely, her legs and shark like tail.
But really, who could possibly forget her tail? Ame spit into her hands, rubbing the widest part of the tail, just where it met up with the base of her spine. She stroked outwards along the tail length, feeling how the smooth surface contrasted against Gura's more human features, then stroked back in towards the base, feeling the sudden roughness… that was unexpected, Ame thought, how much effort did Gura take to make sure her tail didn't scrape against either she or Ina during sex?
In thanks, Ame teased Gura, running all of her fingers down the underside of her tail, praying to whatever Atlantean deity existed that she would feel that when time restarted. And so it was that Ame immersed herself in Gura, writhing and swimming in her, enjoying the feel of her skin, the smell and taste of her the fluids in her mouth and on her skin and in her pussy, fluids which Ame had basically consumed in their entirety and replaced with her own.
Watson's hips started to move and gyrate on their own as she started to grind against Gura's leg, hearing the sound of her slick pussy leaving a telltale trail on the exposed calf before shimmying up to her thighs, enjoying the sight of the helpless shark being thoroughly ravished by her… And without any warning, the dam broke, and Ame's first orgasm shook her to her core.
