Beautiful little monster x cold on the outside, unhinged on the inside top
Pheromones: Pearl Jasmine x Polar Snow
Bai Nian grew up alone in a slum on a garbage planet.
An eighteen-year-old Omega, soft and beautiful, and the object of many people's covetous attention.
By day, he kept company with the corpses of bizarre, misshapen bugs.
By night, the golden-eyed, cat-eared boy on the Star Net comforted countless listeners suffering from insomnia.
Some said he was an angel descended to earth.
Only Bai Nian knew he was a little monster.
One day, the little monster met his guardian.
A cold, unfeeling Alpha general.
But Bai Nian loved the way he smelled.
It reminded him of the endless snowfall in his dreams.
The little monster was shackled and made his guardian's Omega in name only.
He knew the general was always suspicious that he was an insect.
He clasped his left hand behind his back. In the small cracks in his palm, golden tentacles curled uneasily into a ball.
He mustn't... be discovered.
He would be killed.
Late one night, Bai Nian ran into a man who looked exactly like his guardian.
Only his eyes weren't the familiar silvery gray, but a deep, bottomless black.
An Omega in heat had a fragile will, and the secret in his palm was laid bare.
The man toyed cruelly with the soft golden tentacles, his cold pheromones teasing the Omega's gland.
"I can keep your secret."
"In exchange, let me give you a temporary mark."
"Don't worry. Pei Mo won't find out."
The Omega sank into the pheromones, identical to those of his guardian.
The melted snow's domineering cold covered the soft, delicate heart of jasmine.
The next morning, the moment the Omega turned around, Pei Mo clearly saw the bite mark that had yet to fade on the gland at the back of his neck.
His expression instantly turned cold.
Of course. An Omega this pretty and delicate couldn't have survived on a place like the garbage planet without some kind of skill.
Later, the little monster who ran away was caught and thrown onto the bed.
The golden tentacles in his palm were forcibly pulled out and split into several strands. Each one was tightly bound by the black tentacles reaching from the other man's palm, entwined in a desperate, dying embrace.
The monitoring collar around his neck, which he had finally managed to remove, was replaced by a thin silver chain. Its end rested in the Alpha's hand.
Bai Nian sobbed, "Please, don't kill me. I won't run away again."
The Alpha caressed the Omega's beautiful face. Madness flared in his eyes, though his voice was utterly tender.
"How could I bear to?"
He was a demon reborn from hell, and he would defile the divine once more.
Note:
1. A space setting with a touch of cosmic horror, written just for fun. (Though it's probably easy to tell what inspired me, I still have to shout that Nian Nian and Old Pei are not blood-related! There's a ton of original worldbuilding in this story!)
2. On the surface, Nian Nian and Old Pei have an eight-year age gap. The actual gap is up to your interpretation.
3. There may be a side pairing, depending on my mood. It might appear in an extra chapter.
4. I'll add more if I think of anything.
