Syrena though she'd have a little fun trying out some weaponry she captured. The best test subject, is, of course, Riptide, but it seems like he takes offense at being used like that..

The sounds of wet, slick thrusting echoed down the halls of the deserted gym, punctuated only by a female voice, low and throaty. "So, Syrena, thought you could just test your latest toy on me and get away with it?" There's a growl at the end of the sentence, as if the speaker has just found something pleasurable in asking the question.

"Fu-fuck! It's not like that, Riptide! I, ahh ahhh hahh, had no idea what it was goin-going, nnngh, to do!" The second voice was higher, more feminine, and apparently under some sort of duress. It became apparent just what that duress was as the black and white shark gave another thrust of her hips, driving the double-ended dildo deep into the tiger shark's cunt. The brave vigilante looked much the same as he always did, with one important exception - he was now a she. With both participants stripped of clothing, the change was quite conspicuous, from the swells of two shapely breasts where his pecs once were, to the soft folds that were currently home to a thick (and vibrating) slilicone shaft, an adequate replacement for the shark's usual equipment.

The heated thrusting continued unabated, juices running down both shark's groins, mixing together and dribbling into a puddle underneath them, with Riptide's words coming after each sickening sucking squelch. "Thought..uunf..you could just...fuck me over...nngh..like this, huh? Well, two can play at---ahh---that game! Who's getting fucked now?" A gloved hand reached out, grabbing a handful of titflesh and squeezing roughly, eliciting a half-scream half-moan from the tiger shark lying beneath her. "Sensitive, huh?" grinned the blacktip, teeth exposed as her lips curl back in a feral smile, "I should know now. Maybe if you're a good girl, I"ll let you suck on 'em later." Her bust was much less impressive that Syrena's plentiful mounds, but still shapely with metal D-rings dangling from the nips. As the tiger shark clawed at Rip's thighs, the other simply began to speed up, rolling her hips back and forth as she sunk the thick toy deep into the other's folds, savoring the feeling of power she held on top. Through all the moans, whimpers, and cries coming from Syrena's maw, there were also words of begging: 'Faster! Faster' "Harder!' 'F-fuck me!', spurring the vengeful shark on more and more, fingers beginning to work at squeezing the thick nipple.

It took only a minute before the tiger shark finally gave a loud, shuddering moan, voice raising an octave, lips clenching tight around the girthy length as her body twitched and jerked in orgasm, juices splattering onto Riptide's thighs and crotch. Exhausted, she laid back on the floor as the orgasm continued to course through her body, panting heavily, while Riptide grinned contently over her. "Good good, glad we got that out of the way.." Her arms move to hoist the tiger shark's legs over her shoulders, looking down now at her prey. "Don't worry though, I brought plenty of more toys to try out on you. Hope you didn't have any plans tonight, 'cause we'll be doing this until you pass out~" And all Syrena could do was moan as she felt the feeldoe once again slide deep into her cunt, walls clenched tight around it.
