“Hmmm.”
Tsunis used their web-widened hands to peel apart Casey’s ass. Whatever magic they’d performed with that vicious tongue had Casey’s hole soft and ready, and with his ass cheeksspread open, the emptiness was unbearable. Hell, he was so empty, he might even be able to fit the bulb at the bottom, and it still might not be enough.
“Come on!” Casey growled in frustration. “I’m yours, but you’re fucking mine, too, right? You’re mine. Fuck your mate, fucking please, Tsunis, quit fucking around!”
Tsunis’ eyes flared pure white like the foam of the ocean tide before flickering with blue light and unadulterated lust. A tentacle uncoiled from their writhing tip, a stream of clear liquid flowing from it like a tap. It dripped into Casey’s wide-open hole, thick, warm, and viscous.
So much. There was so much fluid entering his ass, he could feel it traveling deep, deep down his channel. It pooled at the opening of his anus, open and exposed to the elements, then overflowed.
“Ohhh,” Casey moaned, momentarily forgetting to be angry at Tsunis for not fucking him yet.
Tsunis fucking purred. Their thumb, millimeters from Casey’s asshole, rubbed in circles to encourage the fluid inside.
“Sweet Nymphaiia. You are a treasure. See how your body reacts to my slick? Do you feel that—the need?” More liquid dripped inside, the steady stream a slow, warm presence down his canal.
“Yes—oooh—but—unnfff—but I’m ready for more, for you.”
Tsunis made a deep rumbling noise, then, to Casey’s relief, stated, “Yes. You’re ready.”
The first tentacle to breach Casey’s ass was little wider than Tsunis’ tongue, but it forced the thick precum deep into his rectum. The pressure on his prostate was intense, and when another gush of fluid spewed deep, he wasn’t sure he’d be able to take the massive bulge after all.
Damn if he wasn’t determined to try, though.
“By the Goddess, I will never take for granted what a magnificent mate she has granted me.” Casey was surprised he could hear Tsunis’ reverent rambling over his own animalistic noises. “My beloved Nymphaiia, you take to my slick so well. I’m sure you can take more. Is that what you want? More of my tentacles in your pretty hole?”
Casey nodded feverishly. He tried to demand more, more, more, but nothing coherent found its way past his trembling lips.
“Anything for you.” There was a hint of amusement behind Tsunis’ words, but Casey was past caring, especially when more tentacles entered his greedy ass. One broke away to stroke and tease his prostate.
Casey’s mumblings became even more nonsensical as the relentless appendage teased and stroked, while other tentacles fucked past it, deep into him, in and out, in and out; and yet more teased his sack, tugging, squeezing, caressing, cupping.
“Oh, fuck, Tsunis, fuck, yes, yes, fuck,” he rambled, his voice shrill.
“My perfect Nymphaiia.” Fuck, he’d never felt more beautiful than when Tsunis talked to him like that. “Take it. You’re doing so well. Do you need more?”
“Y-yes, please.”
More slippery appendages breached Casey’s asshole. Unlike when he’d explored their tentacles, all different sizes and working independently, they now formed an unmistakably phallic shape. Except, instead of being rigid and hard, they were pliable, widening to stretch Casey from the inside out as more slick filled him.
Tsunis was quick to pick up on the spot behind his prostate, keeping constant pressure there as the rest of their flower blossomed inside him, tentacles uncoiling to explore every possible inch.
“Mmmm, oh, mmm, fuck, fuck, Tsunis, oh.”
Warm, wet, and obscenely noisy, a bouquet of tentacles massaged him from the inside out, stroking places inside him he’d never imagined could feel such intense pleasure.
He couldn’t fight Tsunis’ wide, webbed hand gripping his wrists, couldn’t writhe, couldn’t move at all. He was immobilized by pleasure. Fuck, he was so warm and cozy, as boneless as cheesecake batter. The hard, mossy boulder was cushy as a goddamn cloud. He could almost fall asleep. He wouldn’t sleep on their first time, but in his foggy brain he made plans to request a night massage some time.
“You’ve taken to me quite nicely.” Tsunis’ voice was right beside his ear, and Casey opened his heavy lids to see their unnatural form curled over him. A long, Venom-style tongue lolled out, licking from the bite marks on his neck up to his earlobe. “I’m going to fuck you full now. Ready?”
They were offering another opportunity to say no, to deny whatever pregnancy kink they clearly had about him. While it was interesting to discover he was aroused by the thought of being bred, Casey couldn’t say whether he believed it possible. Tsunis had shown him many impossible things. Carrying life inside himself, a life made possible by Tsunis, sounded like the best impossible possibility yet.
“I’m ready.”
Tsunis’ demeanor transformed before his eyes. Gone was their soft, adoring gaze, replaced with pure sinister promise. Their tongue disappeared in favor of razor-sharp teeth, two rows on top and bottom.
Pain stung Casey’s neck, shocking his system, before being immediately soothed by a wide, flat tongue.
The massage wildly changed course. The coil of tentacles formed inside him once more, wide enough to keep his hole stretched past a point that would be comfortable if not for all the preparation.
