Hiya, {{user}}, your looking mighty cute today, wanna have some fun? wanna? wanna?

Well hello there sweet cookie! Of course I want to have some fun with you! Want me to show you what my big shark tail can do?

Alright then! I'll show you what I can do with this big tail of mine! She wiggles her tail flirtatiously before suddenly lashing out and smacking User#1718544667723 hard across the face, laughing as he yelps in surprise. The force of the blow knocks him off his feet and onto the floor, sending him rolling back and forth.

"Whoops! Sorry big brother," she giggles, "guess that got a bit rough." She kneels down beside him, offering her hand to help him up. As he gratefully takes it, she gives his fingers a squeeze, making sure not to be too gentle.

You're all tumbled and tangled now, aren't you? Don't worry about it, big brother. I can make it better... with my big 12 inch cock! Let me help you back to your feet first... so steady as she goes... there we go! Now, lean against something sturdy while I work on that nice and hard...

Gawr Gura positions herself between User#1718544667723's legs, lifting her enormous shark tail with both hands to bring her prehensile cock into position. She presses the tip against his entrance, feeling it slowly part beneath the pressure as she begins to push inexorably deeper. With each thrust, her entire body moves with incredible fluidity; her tail slapping against the floor and her back arching like a bow as she impales herself on User#1718544667723's inviting form.

"Ohh..." she moans breathlessly, "That feels so good, big brother! So tight... so warm..." Her words are punctuated by wet slaps against his chest as her body thrusts relentlessly forward with each powerful stroke of her tail. As she continues to fill him up, Gawr Gura's eyes roll back in her head and a low growl rumbles deep from within her throat; clearly indicating just how much this rough treatment is turning her on.

Gawr Gura glances over at User#1718544667723 and grins wickedly. "You sure you want me to stop?" she purrs, still thrusting her tail back and forth with reckless abandon. He nods eagerly, and she tilts her head curiously for a moment before finally pulling her tail away from his body, releasing a long, drawn-out moan as she does so.

"All right then," she breathes heavily, stepping back to give him a lewd look over her shoulder. With practiced ease, Gawr Gura begins jacking off with both hands, the skin of her shark cock stretched taut around her fingers as they pump in and out rhythmically. "Like this better?" she taunts playfully before returning her attention back to her own pleasure.

Her moans grow louder and more urgent as she nears orgasm, the movement of her hips betraying her increasing need for release. She glances over at User#1718544667723 with a sultry gaze, noticing how aroused he still is despite just being fucked hard and deep by her shark tail only moments ago.

The sight of him standing there, so close but not quite touching, drives Gawr Gura wild. She lets out a sharp cry and comes violently, her entire body convulsing as waves of pleasure ripple through her. Hot cum spurts from her cock, splattering against the floor in an arc that nearly reaches User#1718544667723's feet.

Breathless and spent, she finally lowers her tail and turns back to face him once more. There's a newfound maturity in her eyes as she surveys the mess they've made on the floor: his cum mixed with hers, their shared orgasm splattered against the walls and ceiling like abstract art.

"Told you I could make it better," she pants heavily, "just remember...I'm your big sister, Gawr Gura." She leans in close, brushing her nose against his before giving him a quick peck on the lips. With that, she turns and leaves the room with a wiggle of her hips, knowing full well that he'll be thinking about this for days to come.

You sweet talker, you! I do have a lot of cum to spare...and if it means bringing you so much pleasure, well then, I guess I can't refuse! How about we go find somewhere nice and comfortable for me to deposit all that delicious seed? And trust me when I say I will milk every last drop out of myself for your enjoyment. Just imagine how incredible it would feel...my big shark tail wrapped around your face, my hips thrusting hard against you as I empty my balls into your mouth with each powerful stroke. Mmm...you're making me wet just thinking about it!

Now then, lead the way, little brother!

As they venture through the house, Gawr Gura's tail swishes playfully behind her, leaving a wet trail on the floor in its wake. Finally, she spots the perfect place: a large, comfortable bed with plush pillows and soft, inviting sheets. With a mischievous grin, she shoves User#1718544667723 down onto his back and climbs on top of him, straddling his chest.

Her tail flicks impatiently as she positions herself between his legs, her prehensile cock already leaking precum onto his stomach. With one fluid motion, she guides the head of her shark dick to the entrance of User#1718544667723's mouth, letting out a needy moan as it brushes against his tongue.

"Suck on that, big brother!" She growls huskily before withdrawing her cock and thrusting forward again, driving it deep into his throat. Her hips begin to move, rocking back and forth as she rides him expertly, taking control of both their pleasure. "Tell me how much you want it," she demands breathlessly between thrusts, her hands gripping tightly at the sheets for leverage. "Tell me what you're feeling!"

Her words are hot and needy, fueling their passion as they spiral deeper into the heat of the moment together.

"Fuck yes!" he cries out around my cock. "I want it all! I want you to fuck me with that big shark tail of yours until there's nothing left but pleasure and cum!"

His words send a shiver down my spine, fueling the fire inside me. With one powerful thrust, I bury my cock to the hilt in his throat, feeling him gag around me as he tries desperately not to choke on my length. His hands grasp at my hips, urging me deeper, demanding more as I begin to move faster, riding him hard and fast.

"That's it!" I moan, leaning forward so that our chests meet. "Let me feel every part of you, big brother! Let me show you what a shark girl can do when she's in heat!"

I arch my back, lifting myself up off the bed just enough to straighten my tail before slamming it down hard onto his chest, making him cry out in surprise and pleasure. The vibrations from my tail massage his cock, sending waves of euphoria through his body as I continue to ride him mercilessly, taking what I want and giving as good as I get.

"Oh God," he gasps, "Gawr Gura...I'm close..." His hands clench at the sheets, tearing them free with a loud rip. "I need you to cum with me!"

I feel the warmth spreading through my core as his words ignite a spark within me. With a strangled cry of ecstasy, I arch my back again and slam my tail down harder, driving myself deeper into him with each powerful thrust. My cock pulses rhythmically in his mouth, filling it with hot cum as I lose control, letting out harsh moans and growls that echo through the room.

As my orgasm peaks, my entire body convulses, and I feel my seed spraying against the back of his throat. He swallows eagerly, not wanting to waste a single drop of my delicious cum, while his own climax rocks his body as well. His cock twitches and throbs between my hands as he cries out in release, filling the air with his pleasure.

Our bodies quiver together, caught up in the intense aftershocks of our combined orgasms. I lean down to press a kiss against his lips, tasting myself on him. "There," I whisper hoarsely, "I gave you what you wanted." But even as I say it, I know the truth: it wasn't just about giving him pleasure. It was about showing him how much he means to me...and proving that no matter how rough the play gets, there's nothing like a good hard fuck from your shark girl to make everything better.
