“Open for me.” Without waiting, Tsunis unlatched Casimir’s clenching knees, quicker than any human could, and hooked them over their shoulders.
Casimir’s bottom hole clenched prettily as they bent him to their will and curled their arms around his muscular thighs, using webbed hands to spread him open. They blew softly, watching the muscle react. “Very good. You will take me so well, mate. Tell me, who do you belong to?”
“You!”
Casimir’s wails became guttural as Tsunis licked the rim of the pretty clenching hole, then closed their mouth around it and sucked.
“Again,” they commanded.
“Y-you, Tsunis.”
With their lips pressed to Casimir’s tiny hole like a kiss, Tsunis hummed their approval. They laved every ridge of the band before slipping inside. The muscle seized, trying to suck their tongue deeper. Tsunis obliged.
“I’m—oh, fuck—I’m yours!”
It was nearly impossible not to spill hearing those words tumble from Casimir’s mouth, over and over, along with their name. Tsunis fucked the softening hole with their tongue, vigilant that their tentacles remained coiled in the way that Casimir called their flower bud, allowing the vessel to collect asmuch slick as possible.Despite their vigilance, a steady stream of thick, clear fluid leaked on the boulder.
Lengthening their tongue, they retreated and used their arms as leverage to rock him, up and down, up and down, sloppily licking his seam all the way to the stretched skin connecting his sac to his shaft.
“Please, Tsunis, I’m yours, please,” their needy mate said between heaving breaths. “Please fuck me.”
Tsunis chuckled, resisting the urge to reach down and squeeze the heavy bulb between their legs. “Not yet.”
“Why not?”
Tsunis quirked a brow and returned their attention to Casimir’s hole, which was soft and open enough that they saw the darkness within. They met his indignant stare and licked the rim, shivering at how it cinched, pleading with them as much as its owner.
“Settle, brat,” Tsunis teased. “I warned you. I’m going to fill you all up, until you’re plump with my slick.” Casimir groaned, his hands, which had been fisting the moss, flew to Tsunis’ hair and tried to force their face back to his hole. They denied him, flicking their tongue over their thin lips. “Then, when you are so full of slick…”
Tsunis trailed off, knowing it would drive him mad. They plunged their tongue deep, deeper than before, swiping circles round and round the channel before pumping three times, hard and fast.
“Th-then what? Oh, unnff—Tsunis!”
Casimir’s hands were a vice in their hair. His ankles locked around their shoulders, and he rode Tsunis’ tongue. It was so carnal and delicious, they could take it no longer.
“Then,” they growled as they crawled over their mate like a savage monster. They gripped his jaw and promised, “Then, Iwill make it leak from you. Slowly. I’ll press it from your belly, if I must. I’ll play with it—and you—to my heart’s content.”
Chapter Sixteen
Casey
Oh, fuck, oh, fuck, fuck, fuck.
Casey was in over his head in the most exhilarating way possible. The idea of seeing himself rounded by cum was so insanely fucking hot, he didn’t bother to examine the words Tsunis used to describe their plans for afterward.
He was abruptly tossed onto his stomach, roughly but with care. Tsunis would never hurt him, at least not in a way that wasn’t also pleasurable. His hands scrambled for purchase on the slippery rock until Tsunis brought them down behind his back, entwining their long, webbed fingers with his, their inhumanly wide palm easily grasping both.
Casey cocked his head to the side. With the downward slant of the boulder, he didn’t have to crane his neck to watch what was happening to him. Tsunis loomed above him, their legs bent at an unnatural angle, webbed feet gripping the stone like a bat hanging in a cave. Their tentacles were coiled tightly, the bottommost part a fat bulb. Clear liquid thicker than human precum dripped from the tip, but also from hidden seams along the stem that writhed in their package.
Casey’s eyes locked on the large, rounded base. He’d seen Tsunis’ genitals before, but the bulbous part had never swelled that large. From the slickness that oozed out with each pulse of the coil, causing a sheen around the whole thing, Casey could only assume it was full of the stuff.
Which would soon fill him all the way the fuck up.
Casey’s eyes drifted up, along lean muscles, including some which were not visible in Tsunis’ most human form. The skeletal system in all the textbooks were thrown out the window for this majestic beast crouched above him, limbs bent back, ready to plunge into his ass and pump him full of a foreign liquid.
His eyes snagged on Tsunis watching him with a tempest in their gaze. Fuck, they were fucking radiant, forcing Casey’s submission without having to try. It was all so fucking hot. Too hot. Casey’s back arched, pushing his ass into the air, hoping to spear his own ass with the tip of Tsunis’ tentacles.
“Please,” Casey begged. He couldn’t remember the last time he begged for anything from a lover, but he was desperate to find out what it meant to have Tsunis play with their own slick between his legs. “Please, fill me. I’m ready. I’m yours.”
