The moonlight through the salt-crusted glass paints the room in shifting silver, the damp wood floor cool under Samantha's bare feet. She sits cross-legged on the rumpled sheets, the burgundy silk of her dress pooled around her thighs, one hand resting on the sleeping curve of Lyra's shoulder. The girl breathes slow and deep, her lavender skin luminous in the low light, utterly safe in the trust she's placed here.
Thalassa sits across from her, the sheer silver wrap catching every glint of the single lantern. The Seeth's skin is pale as winter moons, her eyes like twin nebulae—deep violet shot through with threads of living gold. She watches Samantha with the patience of someone who has watched centuries pass, and yet there's a hunger beneath the stillness, a heat that hasn't cooled in five hundred years.
"Ask," Thalassa says, her voice a low melody, like waves pulling back from shore. "I can feel the question pressing against your lips."
Samantha bites her lower lip—that old habit she's never broken. "You said you wanted to show me what I could become. But I don't even know what you are. Not really. The Seeth who took us, they only ever touched us. They never told us about themselves."
"We are not generous with our truths," Thalassa says. A pause. "But I will be. Ask what you wish."
"Mate with each other," Samantha says, and the words feel strange in her mouth. "How do Seeth mate with Seeth? Not with captives. With each other."
Thalassa's lips curl, slow and knowing. The moonlight catches the silver threads in her wrap as she shifts, leaning forward, her elbows resting on her knees. She is close enough that Samantha can smell her—salt and something floral, like night-blooming jasmine.
"It is not like your kind," Thalassa begins. "We do not court with words or gifts. We do not circle each other in dance. When a Seeth desires another Seeth, she simply opens herself. There is a frequency—a resonance. Our bodies hum when we find one who matches. It begins in the chest, a vibration that spreads to the throat, the belly, the sex."
Samantha's breath catches. She tries to keep her face neutral, but her fingers tighten on Lyra's shoulder.
"We feel it across rooms," Thalassa continues, her voice dropping lower. "Across ships. Sometimes across systems, if the bond is strong enough. The first touch is not with hands. It is with the mind—a brush of consciousness, a glimpse of the other's hunger. Then the body follows."
"And then?" Samantha's voice is barely a whisper.
"Then we shed our garments. We kneel before each other. Not in submission—in recognition. We touch faces first, palm to cheek, forehead to forehead. We breathe each other's breath. And then we taste."
Thalassa's tongue traces her own lower lip, a slow glide of pink against pale. "The taste of a Seeth is not like flesh. It is like starlight on the tongue, like the moment before a storm breaks. We lick the salt from each other's throats, the hollow behind the knees, the inside of the wrist. Every place where the pulse beats close to the surface."
Samantha's skin is hot. The dress feels too tight across her chest. Between her thighs, something stirs—a pressure she didn't have before, a weight that wasn't there when she woke. She shifts her hips, trying to ignore it, but the movement draws Thalassa's gaze.
"Then," Thalassa continues, her eyes fixed on Samantha's lap, "when the taste has driven us mad, we open ourselves fully. A Seeth female's sex is not a single place—it is a channel that runs deep, lined with ridges that pulse and grip. The male's cock is not merely for penetration. It is a conduit. When we join, our minds merge. We feel every sensation as if it were our own. The pleasure is doubled, tripled, infinite."
Thalassa pauses. Her gaze lifts slowly from Samantha's lap to her eyes. "You are tense, little keeper. Your body is responding to something."
Samantha's face flushes. "I'm just—"
"You're hard," Thalassa says, and the smile that spreads across her face is ancient and patient and devastating. "I felt it when you shifted. The vibration changed. You have a cock now, don't you?"
Samantha's throat is dry. She can't deny it—the erection straining against the silk of her dress is undeniable. She doesn't understand how it happened. The Seeth must have changed her, remade her body while she was in the pleasure chamber, while she was being reshaped by Vaelith's seed and touch. She hasn't touched it yet, hasn't explored what she's become, but it's there, hard and aching, pressing against her belly.
"Yes," she breathes.
Thalassa's hand moves, slow and deliberate, crossing the space between them. Her fingers hover over Samantha's thigh, not touching, but close enough that Samantha can feel the heat radiating from them.
"May I?" Thalassa asks. Her voice is soft, but there's a current beneath it—a demand disguised as a question.
Samantha's heart pounds. Lyra is asleep beside her, her breathing steady and undisturbed. The room is dim, the moonlight tracing patterns across Thalassa's silver-clad body. Samantha should say no. She should protect Lyra, protect herself, keep some part of herself untouched. But the hardness between her legs is insistent, and the heat in Thalassa's eyes is a fire she wants to step into.
She nods.
Thalassa's hand settles on Samantha's thigh, her fingers long and cool through the silk. She doesn't move immediately—she lets the touch sit, lets Samantha feel the weight of it. Then her hand slides upward, pushing the hem of the dress higher, exposing pale skin. Her fingers trace the inside of Samantha's thigh, a featherlight touch that makes Samantha's breath stutter.
"You're trembling," Thalassa murmurs. "Are you afraid?"
"No." The word comes out too fast, too sharp.
"Good. Fear is delicious, but I want something else from you tonight."
Her hand reaches the junction of Samantha's thighs. She cups the hard length of Samantha's cock through the silk, her palm pressing gently, feeling the heat and the shape. Samantha gasps, her hips bucking involuntarily into the touch.
"Ah," Thalassa says, her smile widening. "You are new to this. The cock is fresh—it hasn't been used yet, has it?"
Samantha shakes her head, unable to form words.
"Then I will be the first to worship it."
Thalassa's fingers find the edge of the silk and push it aside. Cool air hits Samantha's cock—and it's hers, fully hers, a shaft of pale flesh that rises from the dark curls between her legs. It's not as large as the Seeth's, but it's proportionate, beautiful, the head flushed and slick with a bead of clear fluid.
Thalassa's breath catches. "Exquisite."
She leans down, her silver hair spilling forward, and presses her lips to the tip. Her tongue flicks out, tasting the bead of moisture. Samantha's whole body jerks, a cry caught in her throat.
"Taste like new skin and honey," Thalassa murmurs against the shaft. "You are a virgin, aren't you?"
"I have been taken but not since my body changed" Samantha whispers. "I haven't even touched myself since I changed"
"Then let me teach you."
Thalassa's mouth opens, and she takes the head of Samantha's cock between her lips, sucking gently. Her tongue swirls around the crown, pressing into the slit, tasting deeply. Samantha's hands fist in the sheets. The sensation is overwhelming—hot and wet and so much more intense than when she touched herself as a girl. Her hips thrust up, craving more, and Thalassa takes her deeper, her throat opening to accommodate the length.
Beside them, Lyra stirs. A small sound escapes her lips, but she doesn't wake. Samantha holds her breath, frozen, but Lyra only turns over, her hand reaching out in sleep, brushing Samantha's thigh before settling on the pillow.
Thalassa pulls back, her lips glistening. She smiles, her eyes dark with hunger. "Your sister-sleeper is dreaming. Do you want to wake her?"
Samantha's mind is a haze of lust and loyalty. "No. Not yet. She's innocent—she doesn't need to see this."
"But you are no longer innocent," Thalassa says. She strokes Samantha's cock with her fingers, long slow pulls that make Samantha's toes curl. "You are becoming something else. Something more. And I want to be part of that becoming."
"I don't understand what you want from me," Samantha says, her voice breaking.
Thalassa leans in, her lips brushing Samantha's ear. "I want what I have never found. A lasting bond. A keeper who does not flee or die or bore me. I have taken a thousand lovers, and every one of them faded. You are fresh, fierce, and you carry a fire that I have not seen in centuries. I want to see what you become—and I want to be the one who helps you become it."
Samantha's hand moves without permission, landing on Thalassa's cheek. The Seeth's skin is impossibly soft, cool like water at midnight. "I don't know what I'm becoming," she says. "I killed someone. A captor. I broke his arm and snapped his neck and I didn't feel a thing."
"Good," Thalassa breathes. "You are shedding the weak flesh. Now let me show you what the strong flesh feels like."
She takes Samantha's cock into her mouth again, deeper this time, her throat relaxing to take the full length. Her tongue is agile, tracing every ridge and vein, and her hands cup Samantha's balls, squeezing gently. The pleasure builds, coiling in Samantha's gut, and she can feel the pressure rising, the need to release building like a wave.
"Thalassa—" she gasps.
The Seeth hums around her, the vibration sending sparks through Samantha's entire body. Thalassa's hand moves faster, her mouth suctioning harder, and Samantha's hips rise off the bed as she comes, a hot rush of release flooding Thalassa's throat. The Seeth swallows, drinking her down, not pausing until Samantha's body goes limp.
Thalassa sits up, her lips wet, her eyes shining. "You taste like forever."
Samantha lies back, breathless, her body humming with aftershocks. Beside her, Lyra breathes on, undisturbed. The moonlight continues to slant through the glass, painting them all in silver. Thalassa's hand finds hers, fingers lacing together, and Samantha doesn't pull away.
"There is more to learn," Thalassa says softly. "But not tonight. Tonight, rest. Tomorrow, I will show you the Seeth mating chambers. You will see what two of us do when we find resonance."
Samantha's heart pounds. She looks at their joined hands, at Thalassa's ancient, beautiful face, and she feels something shift inside her—a doorway opening that she never knew existed. She does not know what she will become. But for the first time since the abduction, she wants to find out.
