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.
“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.”
