"Nara," Kolo groaned, "are you injured?" The young paladin was paralyzed and lay on his back, toxin from the carrion crawler coursed through him, and although his body was numb, he still had the capacity of speech.
"I am hurt, but I will recover." Nara's blood stained robes were indeed ripped and tattered, held together on one of her shoulders by only a few threads. Her left breast and shoulder were exposed. A wound dripped red on her neck. She crawled over to her helpless twin brother, breathing hard from the recent battle.
"One escaped," said Kolo.
Nara looked down, feebly trying to pull her robes about her. "Yes, it slithered away, but I am certain you delivered a fatal blow."
"Good." The pride in his voice was evident even without a smile to shape the words. "What of Mother?" He followed up.
Nara had pulled her mother out from underneath a broken table, and dragged her gently on her back, next to Kolo. She brushed back a clump of wet black hair, and wiped some blood away. "She's not responding."
"Oh Gods!" Kolo commanded his body to move, but it didn't. It wouldn't. "Can you use your spells? Maybe you can get my arms to move."
"I'm sorry," tears mingled with blood ran down her cheeks. She continued attempting to cover herself, but the threadbare fabric wouldn't stay up. It continuously fell down to her waist. "I only have the stamina for but one more spell, at least until dawn."
"Then don't worry about me. Help mother."
Nara shook her head. "I've tried, but I fear it might be impossible."
"Why?"
"I do not have the required components to cast the spell I am considering," She sniffled, wiping her nose. "I searched everywhere, but the beasts, they destroyed everything."
She motioned around the small, destroyed hut. Broken vials and spilled potions were scattered around, and there was a gaping hole in the side of their home - where the carrion crawlers had broken through.
Kolo willed his body once again, but to no avail. He could move no more than a rock in a meadow could. "What spell?"
"A powerful one." She said bluntly. "I found some lily petals, and I have plenty of virgin blood," She touched her neck, and the small gash thereon, "And thank the Gods, the box of grave dust has managed to stay latched," She looked up to a nearby shelf, "but we do not have the seed of man."
"Seed of man?" Kolo asked.
"A man's permeates." Nara added.
Kolo looked confused.
"Bodily fluids, Kolo." She arched an eyebrow momentarily, but quickly moved on, waving a hand, "I don't have time to explain the details, we're running out of time."
Realization struck Kolo, and he groaned. "Oh."
"I can't cast the spell without all the accouterments."
"Curses!" Kolo swore. "Is there no substitute?"
"No. But don't worry, I'll find another way, I swear it." Nara grabbed an ornate wooden box etched with necromantic symbols from the shelf, and started frantically searching the room.
"How much do you need?"
"Huh?" Nara rummaged through the hut, collecting other components for the spell, barely registering the serious question from her brother.
"How much seed?"
"A vessel full," She held up a cracked drinking horn found within the debris, and pointed about three-quarters of the way up, "Roughly? About this much." She dropped it and continued her search. "But forget about it, I would never make it to the apothecary in time to get some." She wriggled underneath the table, and explored a cupboard. "No, No, No!" She pulled out with nothing other than a pout and a sigh, and threw her hands up in desperation. "I am sorry Kolo."
"Stop, Nara." Kolo commanded. "This is not your fault. And you are not going to find any 'permeates' in a cupboard anyhow."
"I know! But, what else can I do!"
"Calm yourself sister. look. At. Me."
Nara locked eyes with her twin, and found safety and comfort in them. She took a breath, collected her wits, and suddenly it dawned on her.
"You have some? In you? Right now?" She chewed on her lip, and swallowed hard.
"Yes."
"No, no no. I can't Kolo, maybe I can-"
"Nara. Stop!"
"No, I cannot."
"Yes, you can. You must! Now quickly before it's too late. Pull my britches down and set yourself to work."
"Are you sure about this?"
"Yes. But hurry!"
Nara scooted between his legs and pulled at his britches. Her exposed breast jiggled as she worked the thick heavy pants over his muscular abdomen and hips, and when they were released, so too was his manhood. It flopped out, and smacked her in the face with a meaty thwap. She flinched - in surprise of the gentle bop, but swiftly pulled the leathers all the way down to the ankles.
It took considerable effort to maneuver his limp, heavy weight, and when she was done, she was sweating, and panting from exertion.
And then, for a brief moment, she momentarily froze in a dreamlike trance, admiring the first cock she had ever laid eyes on. It was beautiful, and that it was attached to her brother made it no less appealing. She felt the side of her face where moments ago it had brushed against her so unexpectedly.
Her heart skipped a beat, and her nipples hardened.
She shook her head, blinked, and quickly came back to reality.
"What do I do?"
"Grab hold, and work it until you have what you need."
"Work it?"
"As if I were a dairy cow, and you needed her milk."
She looked befuddled.
"Gods, Nara. Work me as if you were working clay, such as pulling a handle for a pot."
"Oh brother, I'm so sorry." Her face blushed red and she took his weighty member into her soft hands. It was warm, almost hot to the touch, and she tentatively began fondling it. "Oh, gods forgive me."
"Worry not about the Gods, sister. Keep going."
"Like so?" she asked, tugging gently upon the flesh.
"Yes. That is quite pleasant."
She toyed with the cock, delighted by its softness and pliability. "Instruct me brother, I know not how to handle a cock, nor how to please a man. I don't want to hurt you."
"You are doing well, take your other hand, cup it, and hold fast to my scrotum. Fondle my sack gently, as you would a piece of dough, and I will rise."
She swirled his balls in her hand, kneading them with care.
"Like this brother?"
"Yes Nara. Clutch tightly now, and stroke me while I get harder."
"Harder?" she replied, unsure, but curious nonetheless.
"Oh yes," He moaned, "I could not resist touch such as yours for long. Soon I will be as hard as that drinking horn. As long, and nearly as wide too."
"Oh dear, from the beast's poisons?"
"No, sweet twin. The only toxins flowing through me now are those which you require, in a brew concocted by the delicate hands of a loving sister. God's Nara, how your brother's broth boils under your warm touch!"
"The seed of man." Nara proudly whispered, tightening her grip around his swelling manhood.
She squeezed his sack tightly.
"Sister, your breast," started Kolo.
She let go of his cock, and pulled her robes "I'm sorry, it won't stay up,"
"A blessing! Show me the other," commanded Kolo. "The sight of your tender mounds will help me create a potent medley. Release them, so that I too might find release."
Nara looked at her mother briefly, and then ripped the remainder of her robe away. She placed the fabric over her mother's closed eyes.
"Forgive us mother."
"Such beauty," sighed Kolo, "I shall stare now, as you continue. Grab hold again. But speak to me dear sister. Let your gentle breath, and soft words bring comfort to us both. For your beauty and touch are sublime, but your sweet whispers stir me deeply."
Nara quickly re-grasped her brother's cock, which had grown considerably. She could feel a pulse therein, which matched the speed and rhythm of her beating heart. "Oh brother, if it weren't for your strength and endurance the beasts would have taken more from me than my robe. They might have taken my life." She swayed, and cooed, moving her tender breasts back and forth as she chewed upon her lip in earnest.
"My hero. My savior." She held the swollen shaft tightly, leaned in close and whispered into his ear. "My brother."
Kolo moaned. And his cock reached its peak.
"My sister. My kin. I would give my life for you!"
"And I you." Nara leaned back up and smoothed her hand up and down. "Can you feel my hands brother? They hold you as tightly as my heart holds you."
"And my love for you grows with every stroke! Keep going, please," Kolo crooned. "Your grip," he instructed, "Tighten it! Wrap both your hands around my cock, like you would the hilt of a sword!"
