Breaking the kiss, I smiled at him before releasing his chin so he could settle his head back against the front of my shoulder. Resting my hands on his chest, I stroked his nipples until he shivered, breath shuddering out of him.
“Now,” I murmured, resting my cheek against the side of his head, “get your cock nice and slippery with the lube.”
I heard him swallow hard as he obeyed, dropping the cock sleeve to pump lube into his palm. His hand was trembling lightly as he fisted his cock, but he let out a long sigh of pleasure. I watched hungrily as he stroked, slicking up his entire length and making the black gleam.
He pumped his fist again, then again as his head tipped back against my shoulder. His knees fell open wider, heels digging into the mattress and cute clawed toes flexing.
I smiled, still playing with his nipples as I murmured, “Okay, that’s enough.”
His fingers twitched, but he obediently let go of his cock. It flexed, the barbs pulsing and more pre-cum spilling onto his stomach.
“Pick up the sleeve.” I waited until he had. “Now slide it down over your cock, Greid.”
“F-fuck,” he breathed, his cock looking achingly stiff as he positioned the sleeve over its tip and began sliding it down.
“Slowly,” I rasped, transfixed as I watched his tapered cockhead emerge from the end of the sleeve, slick and bulbous. I wondered briefly if it was a toy designed specifically for demiurgus—if the material could hold up against the barbs when he worked it over his length. Or maybe he just got through a lot of them.
The first ring of barbs appeared, flaring up after being pinned down by the sleeve. Greid was trembling, panting lightly as he worked the sleeve down to his base—which took a while—before going still, clutching it tight.
“Good boy.” I kissed the side of his head. “Now slowly bring it back up. That’s it.” I waited until the sleeve had engulfed the head of his cock. “Back down just as slow.”
Greid had let go of my leg to clutch at the sheets, twisting the material in his fist. His thighs quaked, breaths leaving him in ragged pants. When the sleeve reached the base again, his dick bucked in the air, more pre-cum threading from the tip.
I could feel the tension in his body—how badly he wanted to slide that sleeve back up and start pumping fast. So I kept him waiting for a few moments, firmly stroking his nipples as we both went still, Greid’s body practically vibrating against me.
“Back up,” I murmured eventually, and he let out a sob of relief as he slid the sleeve back up his length, a little faster this time. I huffed in amusement, nuzzling the wildly fluttering tip of his ear. “I didn’t tell you that you could go faster, Greid. Keep it slow.”
“S-sorry,” he panted immediately, hand trembling as he held the sleeve around the head of his cock.
“It’s okay,” I crooned, dipping my head to kiss his cheek. “Does it feel good?”
“Yes. Fuck, Beryl.”
“Back down again. Slowly,” I emphasised, then kept it up for a few more minutes until Greid was shaking, his hips straining up with every downward stroke of the sleeve, as if he was fighting the urge to plunge his cock through it hard and fast.
“Hold it there,” I said eventually when it was once again engulfing the head of his cock. “Keep it still and fuck it, Greid, until I tell you to stop.”
His breath caught in his throat, hips instinctively flexing until the very tip of his cock peeked out from the sleeve. “I’ll c-come.”
“No you won’t,” I said easily. “Not until I say you can.”
“I d-don’t think I’ll be able to h-hold it.” He swallowed, letting go of the sheets to clutch my leg again. “I don’t want to disappoint you.”
I melted, hugging him to me as I kissed the side of his face. “You won’t, Greid. I won’t let you. Don’t worry. Just warn me when you’re about to come, okay?”
“Okay.” He gripped my leg tighter as he let out a shaky breath and arched his hips, pushing his cock through the sleeve. “Oh f-fuck.”
“God, that looks amazing,” I breathed, rapt as I watched his slick cockhead pop repeatedly in and out of sight. “Don’t stop until I tell you to, Greid.”
It was less than a minute before he was shuddering as he pumped his hips, his free hand moving restlessly over my leg and the blankets. “I’m g-gonna—”
“Stop,” I said immediately, and he let out a shaky exhalation of relief as he lowered his hips until the sleeve hovered over the tip. “Good boy.”
I stroked his chest in soothing circles, giving him a few seconds to calm down. His hearts were pounding under my palm, breaths shuddering out of him. Between his spread thighs, I could see his tail flicking anxiously against the sheets.
“You’re doing so well for me, Greid,” I murmured in his ear, chest squeezing tight when he shivered and turned his face to nuzzle into my throat. “Do you know how wet I am, watching you do this?”
He moaned, the desperation clear in his voice, but tension stiffened his limbs when I rasped, “Time to start stroking your cock again, Greid.”
He swallowed and slotted the sleeve back over the tip of his cock with a trembling hand.
“A little faster,” I said when he slid it down to the base. “Keep going. No stopping until I say you can. And no coming.”
“Oh god.” His body wound tighter and tighter as he stroked his cock, hips thrusting up to meet every downward plunge of the sleeve.
“Keep your hips still,” I said firmly, back to toying with his nipples. “Mm, good boy.”
Dipping my head, I nuzzled his ear before whispering, “Now you’ll think of me whenever you do this.”
He gasped for breath. “I already d-do.”
God, he was so sweet. Deciding to test the waters, I murmured, “Maybe next time I’ll tie your wrists to the headboard and do it myself. See how long I can keep you on the edge until I finally let you come.”
“F-fuck.” His hips jerked erratically as he pumped the sleeve over his cock faster. “Fuck—”
“Stop.”
He whipped the sleeve off his cock with a sob that was tinged with both relief and frustration. I gave him a few seconds, peppering kisses over his ear and the side of his face, before ordering, “Again.”
“I’ll c-come,” he got out, voice ragged.
“No you won’t.”
Groaning warily, he slid the sleeve back over his cock and broke out in a full-body shiver. “F-f-fuck, I’m so close.”
“Again, Greid,” I said sternly, watching as his free hand clenched the sheets, then gripped my ankle, then slid onto his inner thigh, moving restlessly like he didn’t know what to do with it.
My mouth quirked as I leaned down to his ear again. “Do you play with your ass when you do this?”
“Nnngh.” He swallowed thickly, chest heaving as he stroked his cock. “S-sometimes. Most of the time,” he admitted.
I grinned. “Give me your hand.”
He lifted the one off his thigh until I could clasp his wrist and draw it closer. Then I slid his middle finger into my mouth, sucking it and drenching it in saliva. Greid moaned, writhing between my legs, his hand going still on his cock and squeezing hard.
Releasing his finger, I rasped, “Stroke your hole. Don’t put your finger in, though.”
“Oh f-fuck.” He lowered his trembling hand, hitching his left knee higher on the bed to tilt his hips.
His hand slid between his splayed legs, palm resting against his tight sac. A shuddering moan left him as his head tilted back against my shoulder.
