The prince’s room was silent except for the sound of rustling sheets and the distant croak of something large moving through the marsh below the window, and his sister’s soft breathing. Orias was sitting at his desk by the window, the core from the lizard in front of him. He stared at it, his mind lost in thought.
The core was black, with streaks of red running through it; it was a mana core, the source of magic and All monsters had one, and the bigger the monster, the bigger the core. There was no S-rank or F-rank, only the size mattered.
A quiet laugh escaped him.
“Size does matter.”
The core began to glow and he held his hand out, the crystal floating into his palm. On his right wrist, just below the palm, an organ began to glow. His mana crystal. The organ that allowed him to cast magic.
Mana crystals were different for every species. For humans, it was on the wrist, for dragons it was on their chest but one thing in common was only a small handful of people had them.
“Like an appendix, but actually useful,” he muttered.
Pressing the monster’s core against his organ, he closed his eyes and focused. Mana flowed from the core and into his body. The warmth spread through his veins, and he let out a sigh.
“I’m charging my batteries.”
Across the room, Isabella stirred in her sleep, her eyes fluttering open. She looked at her brother and sat up on the right side of the bed; she was used to his late-night ramblings.
“Are you planning on becoming an electric fish?” She asked.
He nodded. “It’s my backup plan if the prince thing doesn’t work out.”
She stretched her arms above her head and yawned. “Well, at least you’ll be able to light up the dark.”
Orias placed the core back on the desk, half of its red color was gone.
“Do you need to charge yours, sis?” He asked.
Showing him her wrist, he saw the same organ as his but fully blue. “Nope, still half-full.”
He shrugged and leaned back in his chair. “If you want to come with me to the capital, you need to be at full mana. You’ll need it for your transformation.”
She crawled out of bed, her boobs hanging free. He couldn’t help but stare. The soft flesh jiggled with each movement and he was entranced. Before he realized it, his face was buried in her chest. The smell of vanilla and sweat filled his nose.
“Sleep, idiot. I’ll charge later before we leave,” she said, her fingers running through his hair.
He exhaled and wrapped his arms around her waist, lifting her up and placing her in the middle of the bed. Her legs parted and invited him. He crawled between them and rested his head on her stomach, just above her pubic hair.
The faint sweet scent of her arousal filled his nostrils. His body heated up and his blood flowed south. A hand touched his cheek, gently caressing him.
“Twice in one night? You’re really desperate, huh brother?” She teased.
“Who knows we might die in the capital, I have to make sure I don’t leave any sisters unsatisfied in this life.” He murmured, his breath hot on her skin.
She pushed his head lower, his face now inches away from her cunt. She never wore panties to bed, always preferring to be free and accessible to him.
Her little bud was already swollen, and the wetness was dripping onto the sheets.
Bringing his mouth down he kissed her clit. A gasp escaped her lips.
“We can’t have you staining the sheets Bella, I have to clean up your mess.” He said.
He licked her, his tongue circling her bud. Her legs wrapped around his head, pulling him closer. His fingers dug into her thighs as he continued to eat her out, her sweet nectar flowing into his mouth.
“Nhng~ brother, I’m close!”
Putting a finger inside her, he curled it and rubbed against her special spot.
Isabella moaned, her back arching.
His sister’s moans were music to his ears, and he continued to thrust his finger.
“Aaah! Yesh, like that! Aaaahn!”
She came, her juices coating his face.
He lapped her up, not wasting a single drop. When he was done, he sat up and wiped his mouth with the back of his hand.
The sight before him was beautiful. His sister was panting, her chest rising and falling rapidly, her nipples erect and her legs spread wide. Her eyes were half-lidded, and her cheeks were red.
Grabbing his dick, he stroked it, the precum smearing on her lower stomach.
Isabella watched him with eyes full of desire.
“Are you going to put it in or not?” She asked, her voice husky.
He grinned and lined his cock at her entrance. Slowly he pushed in, feeling her wetness surround him. She moaned, her hands gripping the sheets.
Orias leaned down, his face inches away from hers. Once he was fully inside, reaching her deepest parts, he stopped.
They stared at each other, their breathing synchronized.
“Can we stay like this for a while?” She asked, her ruby eyes staring into his.
He nodded and brought her into a hug. They stayed like that for a few minutes, just enjoying the feeling of being connected in the most intimate way possible.
Neither of them moved.
A kiss landed on her neck, and he started to move. The sound of wet squelching and the slap of skin filled the bedroom. He kept his thrusts slow and deep.
Outside, something screamed in the marsh and went quiet.
“I love you Bella.” He whispered into her ear.
A smile graced her lips and she tightened her walls around him. “I know.”
He groaned and started to move faster.
The bed creaked under their weight, the headboard hitting the wall.
Orias lifted her legs and put them on his shoulders, his cock reaching deeper than before.
“Ah! Right there brother! Nnngh!” She moaned.
The pleasure was building up, and he could feel his orgasm approaching. Her inner flesh gripped him, urging him to spill his seed inside her.
Going faster, he pounded her harder than before. His glans rubbing against her cervix. The bed was shaking and the room was filled with the sound of their lovemaking.
They kissed, their saliva mixing.
With a grunt, he came, his hot cum filling her womb. Isabella followed, her body trembled and her legs shook. He stayed inside her, his cock still hard.
Slowly he pulled out, his cum leaking from her gaping hole. He grabbed a towel and wiped her clean. The white towel was now stained with their fluids. He tossed it aside and laid down next to her.
She cuddled up to him, her naked body pressing against his.
“Should we tell mom about this?” She asked, her fingers drawing circles on his chest.
He snorted. “That’s a great idea Bella, let’s tell mom that her twins are fucking each other. I’m sure she’ll be thrilled.”
Bella laughed and kissed his cheek. “She’d faint”
Squeezing her ass, he said, “Well, let’s save that for another day. We have a long road trip tomorrow, so let’s get some sleep.”
She nodded and closed her eyes.
The candle on the desk burned down to nothing, and the core sat dark beside it.
