This was going to be the death of Kieran. It truly was.

Do you have any idea what it was like for a dominant alpha in rut to force himself to remain sane, with an omega in heat right there?

Kieran was next to the front door, waiting for whoever it was to bring him a damned collar. Goosebumps formed on his skin as his core temperature continued to decrease.

"Mmm, feels good," Teru moaned, referring to how amazing it felt for the alpha's body to extinguish his heat fever. He wiggled, almost thrashing, to let Kieran know he wanted to be put down.

Once the sly omega was on his knees, he pulled down the hemline of Kieran's pants in one swift motion. His cock sprung out until the head rested on Teru's lips. Kieran's nails dug into the walls, scratching the white paint. He was trying his best not to give in to his instincts. Not yet.

Don't look. Don't look. Whatever you do, don't look, he thought, staring daggers into the drywall.

He felt light nibbles making their way down his shaft before returning to the tip. The size was beginning to swell, a sure sign of an impending knot. Kieran purred deeply from distress. Where the fuck was the collar?

Teru's small mouth tried to blow the enormous length, but he could only take in a few inches. The alpha winced when Teru made nicks with his teeth. These skills were a dead giveaway that it was his first time to give a blowjob. Still, it pleased him knowing no one has penetrated this virgin throat.

Just a peek wouldn't hurt, right? his inner alpha taunted. Kieran did the one thing he told himself not to do – he looked down.

His breath hitched when he saw Teru's shameless face with half a cock in his mouth. Saliva fell down his chin as he attempted to suck. The sounds were unbelievably lewd. Teru had his own dick out, aggressively stroking it with his ass pushed out.

The human's canines were longer than usual. Kieran didn't recall omegas having such a trait while in heat. Either way, it was sexy as hell.

Are you sure you're human? the vamp wanted to ask.

And then that happened.

Panicked, Kieran grabbed a handful of Teru's hair and pulled his cock away. Teru yelped from the roughness.

Kieran didn't mean to but...

He knotted. Again. It enlarged in size. Just a millisecond later, it would've attached itself to Teru's mouth and the last thing he wanted was to suffocate him. Like knotting a uterus, you couldn't just forcefully extract a knot; it didn't discriminate where it wanted to lock and fertilize especially during a rut.

Teru sat there obediently, analyzing Kieran's struggle with heart-filled eyes.

Talking was becoming increasingly difficult, so Kieran growled a warning to the omega. It translated as, Whatever you're thinking, don't do it.

Ignoring the caution, Teru lightly sucked on the tip as if it was a straw before wrapping his plump lips around the head.

Kieran jumped at the sensation. He was going to lose control. Just when he was about to attack...

KNOCK. KNOCK.

Finally.

Kieran cracked the door open and stuck his hand out to accept the collars, not intending to see whoever brought them. "Give it," he gruffed.

Heels clicked on the floor outside. Kieran knew those shoes.

Blaise.

"I overheard Charles asking another doctor to deliver these to you, but I took the liberty of doing it myself," Blaise said with a meddling expression, holding up three yellow collars. "Why do you need them when you can just bite that human already—" He stopped talking mid-sentence and inhaled deeply, smelling the pheromone concoction of heat and rut together.

"Oh...OH!" he exclaimed, coming to the realization of what was happening in the penthouse. The door pushed inward, slamming into Kieran's face and Teru's side. Blaise's sin wanted to join. "Let me in, big brother," Lust cooed.

Teru clung to Kieran's leg and buried his face into the sweatpants, whimpering from the bruise that would show later from being smacked with a heavy door.

The alpha's omega was in danger.

His Pride had enough of people easily gaining access to his territory.

Kieran's cock unknotted, as if knowing he would need to be in top-notch condition in case he needed to defend his possessions. A knot would've deterred him from winning.

His long fangs snapped at Lust's intruding hand, almost ripping off a finger.

"SHIT!" Blaise screamed and dropped the collars - his manicured pinky dangled there with nothing but a shred of skin keeping it attached to the bone. Kieran caught the leather straps mid-air before slamming the door shut. The locks automatically bolted in place, making it impossible for anyone to enter without the code.

Teru shook from the presence of unfamiliar dominant alpha pheromones. Kieran picked him up again before going to the main bedroom. Blaise was throwing a fit in the hallway, but who gave a fuck?

He placed Teru on the bed, who began to spread his legs like a female dog that wanted to be bred. Slick saturated his clothes.

Kieran unlocked the collar and went to wrap it around Teru's throat. With it, Kieran could ravage him all he wanted without holding back.

Teru saw him coming closer with the thick strap and smacked Kieran's hand away. A sliver of revulsion flashed in those lustful brown eyes. "No!" he yelled with a wave of bitter pheromones.

"You—"

"NO!"

Teru moved away from him. His Pride panged at seeing the action since an omega would naturally want to cling to him during this difficult time.

"Yes. No control." His speech was now reduced to basic words. "Be still."

Again, he lifted the collar at Teru, but he grasped Kieran's wrist to stop him. "NO! Don't want. Scared," Teru cried, "I'm scared, alpha."

They had a stare-down – omega vs alpha. Technically, Kieran could use his dominant scent to make him do what he wanted, but he didn't resort to that.

Kieran squeezed tightly on the collar before letting it go. It thumped to the floor. He kicked it under the bed. The bitter smell went away once it was out of view.

He gave up.

The alpha lunged at the omega.

It would be heat vs rut from here on out.
