Chapter Text

To say that Lucifer was nervous was an understatement. Alastor and himself have discussed this several times, and he knew that the Alpha was okay with it. But… the thought of sharing his heat with someone after so long still made him wary. Not so much of Alastor himself, but because of Lucifer.

He wanted this to be enjoyable for both of them. Lucifer knew that he could be clingy and whiny on a good day, but when he was in heat? Things got a lot more intense for him.

Alastor and himself have had sex before. They've done this song and dance. But this was the time where he would be ripe enough to have a baby. And the thought of having Alastor's child? It sent a pleased purr in the back of his throat.

Lucifer just wanted to please his Alpha.

But, there was no going back now. Here Lucifer was, standing behind the door of his Alpha's room. The little Omega brought his hand up toward the door and gave it a knock. Lucifer had suggested that they share his heat within his own room, but Alastor had assured him that they should share it in the Alpha's room. He said that he had a surprise for Lucifer, but he wasn't sure what the surprise could be.

“ Lucifer ~” Alastor purred as he opened the door for his darling mate. “Come in ~” He sing-songed as he motioned for the little Omega to enter his room. 

Lucifer looked so delectable. He had on his comfiest of clothes. A white tee shirt with a yellow duck on the front that was much too big for him, with the sleeves rolling down to show off his milky-white shoulder blades, and sky-blue shorts with even more ducks on them.

Not to mention the smell . His little Omega smelled so good right now. Spiced apples, caramel, and light burnt sugar . 

The fact that Lucifer was in heat? It only heightened the smell. It made Alastor’s mouth water. But he had to control himself. He could taste his sweet little Omega later.

Lucifer stepped into the room and his eyes widened as he got a perfect view of the bayou. Alastor had clearly been getting things set up for the two of them. Lucifer could see the stars more clearly, the moon was bright, the wind was a gentle breeze, and within the middle of the forest area laid a perfect nest that was filled with blankets and pillows.

“Alastor…” the little Omega was so touched and small tears were forming in his eyes. “It’s beautiful .”

Alastor let out a pleased rumble as his little Omega approved of the set up he had done. He knew that Lucifer was nervous about this day. Which was why he was adamant of the two of them sharing his room.

He already had the bayou in his room, so it would take next to little effort to make it the way he knew Lucifer would enjoy. Alastor wanted his little Omega to relax and be comfortable.

And to taste him.

“Let’s get a better view, my little Omega.” Alastor purred as he wrapped his large hand around Lucifer’s tiny one. His little Lucifer was so small , so perfect . And Alastor had every intention of letting Lucifer know it.

Lucifer let out a pleased sound when Alastor grabbed his hand. His Alpha smelled so delicious. He smelled like the forest, smoke, and whiskey. And being close to him made the scent even stronger and he could feel his shorts getting wet already.

Upon entering the woodsy area, Lucifer slowly let go of his mate’s hand to explore the makeshift nest and the perfect settings his Alpha had set up for them. It was absolutely perfect . Any doubts or nervousness were gone now.

Lucifer had chosen the perfect partner. The perfect Alpha . Alastor had wanted his Omega to be comfortable, to feel safe, and to be relaxed. 

But right now? All Lucifer wanted was Alastor on top of him and to become his .

“ Alastor ~” Lucifer purred as he slowly began to remove his clothes. He started with the shirt, tossing that to the side first before removing his shorts. Luckily for Alastor, Lucifer wasn’t wearing any underwear, so his beautiful pussy was out on display with little blonde pubes resting upon the mound. 

“I need you.”

And how was Alastor supposed to deny his perfect little mate what he wanted?

Alastor wasted no time as he rounded upon Lucifer and scooped his little Omega up and into his arms. He kissed him hungrily, his forked tongue running along the King’s bottom lip to ask for entrance. 

Lucifer opened his mouth with a heady moan as he allowed Alastor’s tongue entrance into his hot and wet mouth. Their tongues swirled together and it made the little Omega’s toes curl in pleasure at the taste of his Alpha and from how good it felt.

“Oh Luci ~” Alastor purred as he pulled away from the kiss to move the two of them over to the nest and he placed his little Omega upon it. He smelled so delicious right now. His milky white skin was shining from sweat. His beautiful pussy lips were dripping slick all over his thighs and their nest.

Lucifer was such a delicious mess.

“You smell so divine , my little Omega. Your pussy is absolutely dripping , shall I take care of that for you?” Alastor purred as he licked his Alpha fangs as he stared hungrily upon his little mate. 

He was going to devour his little Omega.

“Yes, please .” Lucifer begged, his legs spreading as far as they could go and he whimpered as the action caused more slick to leak from his folds. His thighs were coated and sticky, but Lucifer was just too gone to care. And this was further proven by how his scent had heightened. 

“How could I ever say no to you, Luci?” Alastor rumbled as he positioned himself so that he was kneeling in front of his little mate. He pressed his face in close to get a better view of his dripping cunt and his mouth watered at having Lucifer’s taste on his tongue.

Not needing further instruction, the Alpha purred as he stuck out his forked tongue to lap at Lucifer’s sopping wet lips. At the first taste of his little Omega on his tongue, Alastor let out a deep groan .

“ Ha !” Lucifer gasped as he felt his Alpha’s tongue on his pussy. The action caused Lucifer’s legs to close around Alastor’s head. Well, they would have , had Alastor not chosen that moment to rest his hands on either side of his little Omega’s thighs.

“You taste so good, my little Omega. I am going to devour all of you.” Alastor promised as he gave Lucifer’s outer lips one last lick before slowly pushing his tongue inside of his pussy. If he thought the outside was delicious, nothing compared to how the inside of him tasted.

Lucifer was losing his mind . Every lick and flick of Alastor’s tongue inside of his pussy was driving him insane with pleasure. His thighs were quaking and shaking beneath his Alpha’s hands. His head was thrown back as his mouth opened wide from all the noises he was making. “Yes, Alastor! More !”

Alastor rumbled in approval from his little mate’s cries and eagerly stuck his tongue in even further. He swirled his tongue around in just the ways that Lucifer liked it and he made sure to hit his g-spot each and every time.

“Ah! Nghh -” Lucifer whimpered as he tried to calm himself, but it was impossible. The way Alastor’s tongue moved inside of him felt way too damn good . With each and every stroke upon his g-spot, it sent the little Omega into a frenzy. “Alastor… Alastor… -ha ! I am going to cum .”

Alastor’s red eyes were hot and hungry as he devoured every shake, movement, spasm, and sound from his little mate. Lucifer was so fucking cute and delicious. But, he didn’t want his little Omega to cum just yet. 

He wanted Lucifer to cum on his cock.

With that in mind, Alastor slowly removed his tongue from Lucifer’s cunt. He watched in amusement as his little mate’s tiny hole clenched upon nothing. He could not wait to have that tight and wet cavern sucking him in.

Lucifer whimpered at the loss. He had been so close . The heat within his lower abdomen was starting to consume him. “Al, I -”

“Shh, I’ve got you, my little mate .” Alastor rumbled as he pulled away for a moment so that he could remove his own clothes. When they had first had sex, he had been… rather nervous about his scars and fluff. 

Now? 

He had no reason to be nervous or ashamed of how he looked.

Lucifer accepted every part of him with no complaint and Alastor returned that sentiment.

Alastor’s cock was hot, heavy, and hard as it was released from his boxers. He was already dripping some pre. How could he not be so turned on when his little Omega tasted so sweet and made such lovely sounds?

Lucifer’s eyes widened in both neediness and desire as he stared at that huge monster cock. Alastor was always big, but now he was even bigger . And Lucifer had no one to blame but himself.

He rather liked it, if he was being honest.

“Are you ready, Luci? I am going to pump you full of my fawns.” Alastor promised as he wrapped one hand around his large cock and began pumping it slowly, his dark red eyes never once leaving Lucifer’s shaking form. His mind was starting to cloud with the thoughts of getting Lucifer pumped full of his seed and round with his fawn.

Lucifer was absolutely shaking right now. The prospect of having Alastor’s cock inside of him, becoming filled with his knot, perhaps a fawn ….

He wanted that.

No, he needed it.

“ Please .”

“I love it when you beg me, Omega .” Alastor rumbled as he moved so that he was laying on top of Lucifer. He leaned his face in closer and began to kiss his little mate.Alastor loved the taste of Lucifer’s mouth and he eagerly drank up any sounds that he made.

With a free hand, he guided his rock-hard cock to Lucifer’s wet lips and gently nudged in between his hole and clit. The action causes the little Omega to moan within the kiss and arch his back. 

“Inside.” Lucifer whined as he pulled away from the kiss, his breath coming out in heavy pants and his chest was rising and falling from how excited and horny he was. “Inside, now .”

Alastor growled at the demand. He had wanted to take things a little slower, but oh well .

He must give the King what he wants, after all.

With a grunt, Alastor shoved his huge cock within Lucifer in one go. His balls smacking against his ass and he threw his head back in ecstacy. His little Omega’s tight and wet heat was sucking him in so well . It took everything he had to not start plowing into his cunt.

Lucifer let out a scream, his eyes rolled to the back of his head as Alastor’s fat monster cock was pressing inside of him in all the right places. His inner walls clenched around his cock, as though his pussy were trying to draw him in further. His abdomen had a small bump from where his Alpha’s dick laid within him…

And his g-spot… his cervix … 

Alastor’s monster was resting against it and it was driving him absolutely mad . 

“ Fuck !” The little King shouted as his body shook and tried to move, but Alastor’s body was so large compared to his own and he completely engulfed him, which made it impossible for him to move.

And Lucifer loved it.

Alastor chuckled deeply at Lucifer’s reaction. He waited for half a millisecond before he began thrusting inside of his little mate. His cunt was so tight, was so wet , and his little Omega was sucking him in so well. 

Alastor was going to break him.

After that first initial thrust, Alastor began pumping his cock into him harder and faster. His mind had gone completely blank aside from the fact that he needed to breed. He needed to impregnate. 

“Ngghhh….fuck, fuck, fuck, FUCK !” Lucifer screamed as he came as his Alpha practically plowed into his cunt. With each thrust, his body was moved by the force of them. He had drool running down the sides of his mouth as his Alpha kept hitting his g-spot with each thrust.

Even though Lucifer had practically orgasmed at least once or twice, Alastor kept going. All his mind could supply him with was breed, breed, breed and get pregnant, get pregnant, get pregnant . 

It didn’t matter that the little Omega’s cunt clenched around him. The tightness of his cunt drove him to fuck him harder, faster, deeper .

Lucifer couldn’t even form words at this point. His Alpha was breeding him so well. His mouth hung open as he silently screamed and held onto Alastor’s arms like a lifeline, his claws digging into his arm and breaking the skin.

The bayou was filled with skin slapping against skin, the wet sloshing and plopping noises of Alastor’s cock driving in and out of Lucifer’s cunt, and the noises coming out of their mouths.

Alastor was growling, grunting, and groaning as he continued to fuck his little mate. He could feel his knot forming and he smirked widely. “Take my knot, Luci. Take it .”

With one final thrust, Alastor shoved his knot inside of Lucifer and groaned as he came, his hot and thick seed pumping straight into Lucifer’s womb. There was so much cum that it slowly trickled out of his little mate’s pussy. It landed within his inner thighs and their nest.

Lucifer saw stars as he came around that fat knot, his pussy tried so hard to clench around that thick length, but it was too big.. Too thick. He whimpered as he could feel Alastor’s seed seep into his womb…

…and Lucifer knew that it would take.

He was definitely pregnant.

Lucifer didn’t have much time to think of that though as Alastor shifted and he whimpered as his cock was still locked in place, making sure that his little Omega took his seed and got pregnant.

“You did so well.” Alastor hummed as he leaned down and gently kissed Lucifer’s forehead. They were both sweaty, but the Alpha didn’t seem to mind. He rather loved his little mate being a mess.

Lucifer wouldn’t be himself if he wasn’t.

The little King hummed at the compliment and gently nuzzled against Alastor. He was content. He was happy . However, his eyes widened when he realized that Alastor’s cock had not softened after some time and he wondered what that was about…

But then he looked into Alastor’s eyes and he knew that he was fucked . (Pun intended)

“Oh Luci ~ I believe that I should keep fucking you. Just to make sure that you take my fawns .” Alastor smirked evilly as he loomed over his lover.

And Lucifer shuddered hard and swallowed thickly.

 Oh deer.
