Chapter 15 - NSFW

~ No one's pov:

"ahh- ahn-"

Soft moans echoes through the room, although it soon became unbearable for the omega.

"Stay still, Luci.. It won't be the same as the previous night," Diavolo growls threateningly into the omega's ear, making the omega whimpers in response.

The alpha kept a close eye on the omega as his fingers on one hand toys the omega's hardening nipple, it made the omega's body twitched and even gripping on the sheets.

'fuck.. I'm gonna die..' the omega thought negatively, yet his mind and body aren't on the same page of the story. His body enjoys it as much as he mentally denies it.

"D-Diavolo.. ngh~"

Lucifer whimpers out Diavolo's name, turning his head to the side so he could see the alpha behind him, whose definitely kissing the omega's shoulder and neck.

The fallen angel's fingers hooked the demon prince's pinky finger that's rubbing the omega's nipple so deadly gentle. It made the omega let out a low growl of impatience.

Diavolo noticed this and bites into Lucifer's shoulder that connects with his neck, making Lucifer gasped of the slight pleasure. Diavolo made sure to avoid marking him on his scent glands, he won't mark him. Not yet.

As Lucifer kept breathing hotly, Diavolo trailed his other hand down the omega's chest to his stomach just below the belly button, pressing on the spot where his womb should be located from the outside. It made Lucifer flinched and moaned softly.

The Alpha scanned the space between his fingers on Lucifer's womb and Lucifer's wet entrance that's rubbing against Diavolo's hardening shaft through the cloth, Diavolo then leaned in and kisses the omega's ear.

"..I'll have to reach this further inside you, yes?"

Diavolo softly growls as he kept pressing the spot and rubbing his finger on it, making Lucifer twitched in pleasure. Although Lucifer only let out whimpers and small moans, Diavolo could tell he's enjoying himself.

Upon the slightly unbearable sensation, Lucifer's other hand grabbed Diavolo's tightly; trying to pry the Alpha's finger from his stomach, which makes Diavolo chuckled in response.

"We've done this before, haven't we? It shouldn't be a problem you couldn't handle, Luci.."

Diavolo whispered as he kisses the back of Lucifer's ear, and it made the omega turned his head away with his hand covered that ear. Lucifer is trembling, "It just seems as though you are n-not gonna ask if I'd want you to..-"

"I don't have to," Lucifer flinched forward as Diavolo pressed his hardened shaft on the omega's soft bum, rubbing it against the slicked entrance of Lucifer's ass. Lucifer couldn't help but whimper at the slightly daring friction.

Noticing this, the prince moved his hand to grab under Lucifer's thigh and pulled apart the omega's legs, exposing his wet hole into view. Lucifer softly gasped as cold air hit the slicks on him and shivers, he grabbed the Alpha's hand that's gripping his thigh so tightly.

"w-wait, Dia.."

"yes?"

"This position is uncomfortable..," Diavolo couldn't see it, but Lucifer is blushing so madly that even his neck and ears turned red. And as the one to ensure Lucifer's heat to be taken care of, Diavolo stopped his teases and attempts before pulling Lucifer by the shoulder and pushed the omega onto his back on the bed.

Lucifer's breath hitched as Diavolo hovered over him and even keeping the omega's legs separated by his massive thighs. As those previous nights, the sight of Lucifer being all red and vulnerable gets him on edge – not to mention Lucifer's sweet scent that's covering the whole room.

Diavolo looked like a beast in Lucifer's eyes, the omega could barely see the Alpha's face at all. Both of Diavolo's hands are on either side of Lucifer's ribs, his thumbs continued to play with the fallen angel's nipples as he held him firmly under himself.

"You will have to look at me while I please you, alright?" Diavolo requested, his thumb started to rub circles on Lucifer's nipple. And the Alpha couldn't help but rubbing his member on Lucifer's, he needed that friction, that feeling of having this omega's skin against him.

Diavolo is not in rut. Nor even nearing that heat but seeing Lucifer this vulnerable and needy and at the same time, in denial of his heat – Diavolo couldn't help wanting to feel Lucifer again. Lucifer's scent is killing his senses.

Lucifer flinched as Diavolo grinds that massive shaft against his own, that his own cock hardened a bit more and throbbed. The omega is gritting his teeth as he let out a low moan, while Diavolo leaned down and kisses Lucifer on his Adam's apple, feeling that muscle slightly twitching within Lucifer's neck..

"Ahn.." Lucifer whimpers softly as he grounded his feet on the sheets, the omega also had started to buck his hips volunteeringly. Their throbbing hardness squeezed together between their bodies, making both of the men groaning.

"That's it.." Diavolo moved one of his hand down Lucifer's side and grabbed onto the omega's juicy ass cheek, softly. He'd pull Lucifer's hips against him more, while he humps against Lucifer a bit faster. The Alpha wants to make sure his omega is willingly spreading his legs.

Lucifer arched slightly as Diavolo increased the pace of his grinding. He, subconsciously, lifted one of his legs over Diavolo's arm as the omega is giving access to Diavolo to reach his heating hole.

"D-dia..!" Lucifer moaned. That's it.

The alpha lets out a deep yet soft growl, before pulling his hips back from the omega's. His golden orbs scanning the fallen angel's body – the slightly well-built muscles wrapped under the fair toned skin and the reddened and slicked intimate parts of him.

"..so beautiful," Diavolo praised.

The prince couldn't help his lips from grinning slyly from the sight, as his body shifted a bit more against the fallen angel's, "I'll have you.." the tempted alpha growls.

Lucifer held his breath as he shuddered under the prince's predatory gaze, that he missed out the important thing they both need of the situation. He let his pride slipped off of him and started to desperately grind against the alpha's throbbing shaft.

"Dia.. please.. I n-need you.." Lucifer panted. He flinches as he felt the prince's grasp grew tighter on his waist. He can feel Diavolo's length, the head of it, beginning to force it's way inside of his body.

"My omega," Diavolo thrusted, aggressively.
