He’d never knotted inside anyone, but that thought yanked at something visceral inside him.
Kai wasn’t thinking about it. He leaned forward, burying every last inch of his cock into Micah. Then he reached past Micah’s shoulder, and shoved his slick-coated fingers into Spike’s mouth.
Spike groaned around him. He sucked Micah’s taste from Kai’s fingers like how he would Kai’s cock, his tongue damp, the sucking pressure in his mouth sending a jolt straight to Kai’s balls.
Kai swore, snapping his hips up, grinding against Micah’s prostate. Micah shuddered against him, his ass squeezing.
But this wasn’t enough. Kai wrapped his arms around Micah, lifting him up. Then he shuffled forward and dropped Micah onto Spike, Micah’s legs opening around his other alpha.
Spike grinned, reaching between Micah’s thighs. He touched where Micah’s hole had stretched open around Kai’s cock, drawing an embarrassed whimper from the professor.
Micah was so damn sweet. And Kai’s hunger thickened. When Spike caressed Micah’s cock, Kai fucked deep, grinding Micah against Spike’s palm. Micah writhed.
“He fucks hard, doesn’t he?” Spike whispered.
Micah whined, his body damp with a sheen of sweat. Gods, he sounded good.
Kai shoved their omega down against Spike, then fucked deep into Micah, rolling his hips, grasping Micah’s cheeks and spreading them so he could see Micah’s hole clinging around him, tight and pink and trying to suck all the come out of Kai.
Spike planted his feet on the mattress, lifting both himself and Micah. It was a good angle, perfect for Kai to plow inside their omega.
“Gonna come,” Kai gasped, his cock swelling, his balls pulling tight, so fucking heavy with need.
“Come inside him,” Spike whispered. “Knot him. I want to see him take your knot.”
Kai growled, his cock pulsing, the tightness of Micah’s body easing the pressure in his cock. Spike shoved Micah down onto Kai, and Micah made a helpless, choked sound, his entire body squeezing like he was coming a third time.
Kai’s release ripped through his body like a thunderclap. He grasped Micah’s hips and buried his cock deep, pulsing, spurting jets and jets of come into their omega.
He leaned in and almost sank his teeth into Micah. Almost.
Kai glimpsed the silvery bite mark on Micah’s scent gland, and stopped himself at the last moment. That’s my mark.
And now that marking kind of felt right on Micah’s shoulder.
Thoroughly emptied, Kai fell forward, spasming with pleasure. Strong hands caught him. Kai fumbled with the sheets, finding some support before he crushed Micah under his weight.
“Fuck,” he rasped, trying to catch his breath. That had been different from sex with Spike. Less animalistic fighting, more pleasure for Micah.
“You made Micah come a third time,” Spike whispered, his breathing ragged. “So—So fucking hot when he—when he came all over me.”
Then his voice broke, and Kai cracked his eyes open, in time to watch Spike’s face scrunch up as he came.
Yeah, that was always hot, too.
Kai reached around Spike, pulling them all onto their sides so none of them would be crushed.
Then his knot began to swell—he’d never knotted inside an omega before. Kai snuffled, about to pull out on instinct.
But Micah touched his hip, looking over his shoulder. “Stay,” Micah whispered. “Kai.”
Kai swallowed hard. He met Spike’s eyes—Spike, who had begged time and again for Kai’s knot, except Kai had never dared give it to him. Maybe he’d been afraid that he wouldn’t want to let go of Spike if they ever got that intimate.
But Spike wasn’t jealous. He grinned, squeezing Kai’s hip.
“I’ll knot inside Micah,” Kai rasped, forcing himself to stay. Just this once.
Spike wriggled, satisfied. “You’re the first person he’s ever knotted with, Micah,” Spike whispered. “Tell me if it’s good.”
Micah’s flush went all the way up to his ears. Kai wished he could see Micah’s face—he could already imagine Micah’s eyes darting away, his tongue licking over his bitten-red lips.
“I-I will,” Micah said. “But shouldn’t you be the one...”
“I’m happy that you’re Kai’s first,” Spike answered, brushing Micah’s cheek tenderly. “Just like you were mine, and I was his.”
It was sappy as hell. If Spike had said that earlier today, Kai would’ve felt left out again.
Except his knot grew inside Micah, a firm pressure stretching Micah open, and this... it was intimate, too. He’d had Micah for himself. He’d mated roughly with Micah, half-expecting Micah to stop him, except Micah had welcomed every savage thrust.
It felt like Kai had forged something with Micah with that sex—trust, intimacy. And now Kai was here with Spike and Micah, tangled with them. He wasn’t on the outside looking in anymore.
So seeing Spike soft like this, caressing Micah, making sure Micah was happy... it made something in Kai’s heart settle.
Something in him whispered, Spike’s a good alpha. He’s important to me. I want him.
And then Kai needed to see both their faces, except he couldn’t, knotted behind Micah as he was.
Kai shuffled into a half-sitting position, his full knot tugging inside Micah, sending pleasure thrumming through their bodies. He grunted; Micah gasped, and Spike grinned.
“One of these days, we need to make you come like that,” Spike whispered, patting Micah’s cock. “Kai fucking you with his knot.”
“Not sure I can do that,” Kai muttered, rolling his hips to test the give. Pleasure slid through his veins. “No space to fuck.”
“There’s grinding.” Spike raised his eyebrows. “Gotta get creative, Kai. I’m gonna beat your record.”
“Of?”
“Making Micah come thrice.” Spike wriggled. “Between you and me, I think Micah’s come reservoir is gonna get drained so dry.”
Micah yelped, his face turning beet-red. “Spike!”
“You know it’s true.” Spike grinned. “But maybe after you recover from today—Kai seriously fucks hard. Your sweet ass needs some TLC now. All the tender lovin’.”
“By you?” Kai asked dryly.
Micah clammed up, his ears pink.
Spike perked up. “You know, what if TLC meant ‘tender loving cock’? Tender loving come?”
“He’s a potty-mouthed lecher,” Kai said, touching his knuckles to Micah’s back. “Ignore him.”
Spike grinned, reaching
