Mello ran his tongue over his teeth, feeling the slight sharpness as it hit his canine teeth. He crouched lower, watching carefully from the shadows.
Mello had known he was compatible with Matt from the moment he met him. His scent had been absolutely addicting, driving Mello’s alpha instincts wild. He had to have him for his own.
It had been at the gas station, Matt had been buying a pack of cigarettes from the cashier. To a normal alpha, the smell of smoke might’ve covered Matt’s scent, but Mello always had a good nose. The moment he first caught wind of Matt, he had to have him.
It wasn’t too hard after that to track Matt down. Mello had followed the boy home several blocks to a rugged little apartment building. From there, Mello discovered Matt lived in apartment 121A.
Everyday Mello would watch Matt, making sure no other alphas marked him along with waiting for the right moment to do it himself.
Mello shifted in the shadows, watching as Matt stepped out of his apartment building. Mello knew that Matt regularly went outside for smoke breaks, often taking walks during them.
With a small spark of a lighter, Matt’s cigarette was lit. He put the cigarette to his lips, exhaling a large puff of smoke as he started to walk down the dark street.
Mello had chosen this time for a reason, it was always dead in the middle of the night and Matt was a night owl. It was perfect.
As Matt neared where Mello hid, Mello pounced, springing from the shadows and grabbing at the omega. He managed to pin the boy down.
“Let me go-“ Matt struggled.
Mello licked his lips, leaning down and biting into the back of Matt’s neck, claiming him as his own. Matt was officially Mello’s mate.
Mello grinned, wiping the small amount of blood from his lips as he admired the mark he had given Matt.
Matt seemed panicked, writhing under Mello, and Mello understood why. He didn’t know that Mello wasn’t going to hurt him, he wanted to protect him.
“That’s enough struggling.” Mello said. “I marked you, you’re mine now.”
Matt turned his head, the blood from his mark dribbling down his neck. “I’m not-“
“Omegas listen to their alpha.” Mello said harshly, standing up. He was thrilled as he looked down at Matt. He was finally his.
Mello picked up Matt gently, cradling him in his arms. “My place is only a little ways away, I’ll carry you.”
Matt slumped in Mello’s arms, letting Mello carry him. Mello knew that eventually he would make Matt happy, that was his job now that he was his mate of course.
Mello reached his own apartment, he had been preparing the place for the omega. Watching Matt he knew the boy loved video games, so he made sure to buy plenty. The place was also littered with treats that Mello knew omegas craved during heat.
Gently, Mello set Matt onto the bed.
It seemed Matt was tired, which made sense, being marked was a big deal for an omega as their body prepared to mate.
Mello brushed the hair from Matt’s face and pressed a kiss to his forehead. The boy didn’t even seem to mind, which surprised Mello, as Matt had always seemed like a fighter, even if he was an omega, though he supposed Matt’s omega instincts had kicked in and made him become docile.
Mello crawled into the bed next to Matt, curling up around the boy protectively.
Eventually, he fell asleep.
Mello woke up to warmth.
At he blinked his eyes open, he smiled at the sight of Matt being beside him.
However, Mello quickly realized what was up. His nose twitched as he smelled something delectable, but at the same time hot and heavy.
Matt gripped the sheets tightly, a dark blush spread across his cheeks as sweat dripped down his face. He panted loudly, squirming.
“Oh, you’re having your heat.” Mello hummed, propping himself up in bed. He smiled at the sight that Matt already had an erection.
Matt whined, shutting his eyes tightly. “T-this is the worst heat I’ve ever had-“ He stammered.
“Well, it’s probably because you just got marked.” Mello said, tapping a finger to his own neck.
Matt groaned, “Just, please-“
Mello didn’t hesitate to give him what he wanted. If Matt wanted Mello to breed him, then Mello didn’t need any convincing.
Mello ripped off Matt’s pant and boxers, tossing them carelessly to the side. He spread Matt’s legs.
Mello pressed his dick against Matt’s hole, not quite pressing in yet.
“So we’re mates now.” Mello pointed out the obvious, tilting his head just slightly.
Matt groaned, clearly just wanting Mello to fuck him. “S-so?”
Mello smiled, “I just wanted you to recognize that.” He thrusted into Matt, making the boy cry out loudly in pleasure. “So when I breed you, you know exactly who your alpha is, nobody else.”
Mello picked a steady pace, fucking into Matt. Matt moaned, throwing his head back. The redness in his cheeks stayed, but Mello noticed Matt’s body seemed to cool off slightly.
Mello leaned his head down, taking in Matt’s sweet scent. Just a smell of it had Mello fucking Matt harder, thrusting deep.
His instincts took over as he began to suck on Matt’s neck, leaving hickies. When he had fully covered Matt’s neck in them, he moved to his chest and collarbone, sucking more.
Matt groaned and Mello felt sticky warmth against his stomach as he continued sucking hickies. He leaned a hand down, touching Matt’s dick as his cum dripped down the shaft.
Mello thrusted deep, grinding as he came into Matt’s ass, filling him up. He made sure Matt took every drop of cum before pulling his dick out.
Matt breathed heavily, clearly better from his heat as he stared up at Mello.
Mello stared back down at him, “You’re mine now.” He said, getting up from the bed.
