When the ten-foot Seeth—their night-sky eyes and soft skin hiding the tentacles coiled in their backs—abduct twins Alex and Samantha, they don’t just want their bodies; they want the hatred between brother and sister. The Seeth kill as easily as they rape, consent is a turnoff, and virgin siblings who can’t stand each other are the ultimate prize. Now Alex and Samantha must survive a ship of bizarre, beautiful aliens who will force them to mate with each other—or die trying to refuse.

MEET THE CHARACTERS

Alex

18 years old, 6 feet tall with a lean athletic build honed by years of competitive swimming. Short-cropped blond hair and sharp blue eyes that hold a permanent edge of resentment, especially when his sister is in the room. A dusting of freckles across his nose is the only soft thing about him—everything else is coiled tension and quiet defiance.

Samantha

Petite and deceptively delicate at 5'3", with a soft femininity that masks an iron will. Long platinum-blond hair cascades past her shoulders, framing a heart-shaped face with wide hazel eyes that can go from innocent to venomous in a heartbeat. Full curves that she's self-conscious about, though she'd never admit it—she carries herself like she's daring the world to underestimate her.

Vaelith

A towering Seeth female standing exactly 10 feet tall, her body a symphony of impossible elegance and predatory grace. Skin the color of moonlight on still water, impossibly soft to the touch, stretched over muscle that moves like oil. Long silver hair that seems to have its own gravity, and eyes like twin galaxies—deep violet shot through with pinpricks of starlight that swirl when she's aroused or angry. Full breasts that strain against the living silk she wears, and between her thighs, a cock that would make human men weep—thick, ridged, and always half-hard in her presence.

Zarven

A male Seeth with skin the color of burnished bronze and hair like a waterfall of obsidian, falling past his shoulders in waves. His eyes are deep amber shot through with threads of molten gold, and his face is all sharp angles and cruel beauty. Standing 10'3", he's broader than Vaelith, with a chest that could cave in a human skull and hands that look made for violence—but his cock is what draws the eye, a monstrous length that hangs heavy even when soft, lined with subtle ridges that promise both agony and ecstasy.

K'lthix

A creature from a methane world, standing 7 feet tall on four segmented legs that end in delicate three-fingered hands. Its upper body is humanoid but wrong—translucent skin revealing organs that pulse with bioluminescent blue light, a face with too many eyes (seven, arranged in a crescent) and a mouth that splits sideways when it speaks. Between its legs, a slit that can extrude a glowing, prehensile organ that pulses with heat and light.

Ryll

A captive from a water world, Ryll is a humanoid female with skin the color of seafoam, smooth and slick to the touch. Her hair is a mass of living tendrils, pale green and constantly moving, sensing the air around her. Gills pulse at her throat, and her eyes are solid black with no iris or pupil, depthless and unnerving. She's 6 feet tall, slender, with small breasts and wide hips, her body built for swimming through crushing depths—and for wrapping around a partner in ways that leave them breathless.

Assessment Protocol

The cold air hits Alex's skin as the Seeth peel away his clothes, leaving him exposed on the examination slab. Across the room, Samantha is being stripped too, her full breasts bared, her long hair spilling over the metal as she twists against her bonds. Zarven's amber eyes trace the length of Alex's body, lingering on his cock with a predator's interest. 'Virgins,' the male Seeth breathes, his voice like grinding stone. 'The family bond will make them exquisite.' Vaelith's hand glides up Samantha's inner thigh, and Alex watches his sister's back arch, hears her bitten-off moan of shame. Their eyes meet across the chamber. For once, the hatred isn't there—just terror, and something that looks like a plea. Alex's cock twitches, and he can't tell if it's fear or the way Vaelith's fingers are disappearing between Samantha's legs.

Spiral Together

His hand wraps around his cock, and the feel of his own palm—dry, calloused—is nothing like the silk of her skin, but he strokes anyway, slow and deliberate, matching the rhythm of her fingers. Her eyes track every inch of his shaft, her lips parted, her cheeks flushed in the starlight. She whimpers when he speeds up, and he feels the power of it—the way she's unraveling for him, the way her body answers the sight of his. The air thickens with the smell of her, sweet and sharp, and he knows she's close because her thighs start to shake, her knuckles white where she grips the sheets. He sight and smell of her consumes him and he strokes his cock harder and faster to his sister.

Chapter 3

Alex and Samantha stare at each other longingly. They struggle with the idea of fucking each other. They want it but don't want to give in to desire. Alex's cock hardens under his skirt, it pokes out and Samantha's pussy moistents at the sight. Her silk dress becoming wet from her pussy. The walls hum with the pleasure of both. Alex feels Samantha's desire through the wall and Samantha feels Alex's hunger through the wall. Samantha likes how her brother looks in the skirt. Alex is hesitant but Samantha takes charge and convinces Alex that if they don't then the seeth will kill them.She slowly gets on her knees in front of Alex, ready to suck her twin brothers cock

Zarven tells them that if they are submerged in this they can turn younger. Zarven tells Alex. You wanted to be taken younger nows your chance. How old did you wish to be taken?

Your body would change but your mind stays as it is now. Zarven picks a young age, before Alex could even get hard. Alex says yes daddy and proceeds to the age regression tub.
