The ship’s quiet hum was a steady backdrop to Osa’s voice. She lay nestled between Kichijō and Olanke on the bunk, the scent of their shared sex still heavy in the air. Her dark skin was slick with drying sweat, her small breasts rising and falling with each breath. She traced a finger over Kichijō’s tattoo, her voice low and confessional.

“My brother’s cock, ” Osa began, the memory vivid, “wasn’t like Vas’s. It was human. But it was... formidable. Long, and thick. A thick cock with a thick, plum-shaped head. It curved just slightly upward.” She shifted, a ghost of a smile on her lips. “When he was fully hard, a single vein would stand out along the underside, pulsing.”

Kichijō propped her head on a hand, listening intently. Olanke’s blue fingers stroked Osa’s bare shoulder.

“That first night of his vacation, ” Osa continued, “he was relentless. Five times. He fucked me like he was trying to claim something, like he was planting a flag. Missionary, doggy, me on top... each time, he’d hold my hips and just... pour himself into me. I’d feel his cum, hot and so much of it, flooding my pussy, dripping out of me after. My cunt would be so full, so used, and I’d be lying there, feeling it leak onto the sheets, and I’d just want him to do it again.”

Her own hand drifted down between her legs as she spoke, her fingers brushing over her own tender, swollen lips. She was getting wet again, just from the telling.

“The second day, four more loads. He’d wake me up with his mouth on my clit, and I’d be soaking before I was even fully awake. He’d tease me, sliding just the tip of that big head against my opening, making me beg for it. My pussy was so tight for him at first, always so tight. But he’d work it open, so gentle, so slow, until I was begging him to fuck me properly.”

Olanke’s breath hitched. “You begged?”

“Constantly, ” Osa whispered, her eyes closing. “I’d be spread out beneath him, my legs hooked over his arms, and I’d be pleading. ‘Please, fill me up. I need it. I need your cum deep inside me, I need to feel you claim my womb.’ It was... filthy. And it made him fuck me harder.”

Her fingers slipped inside herself, a soft gasp escaping her. She was mimicking the memory, fucking herself slowly with two fingers. Kichijō watched, her own arousal a sharp scent in the air.

“After he went back to work, it was twice a day. Morning and night. My pussy adapted. It was always ready for him, always wet, but it never stopped feeling incredible. That stretch, that fullness. I became obsessed with it. With the way his big cockhead would catch on my entrance every time he pushed back in. The sound it made.”

Osa opened her eyes, looking at her crewmates. Her expression was raw, hungry. “Do you know what it’s like? To have a man who knows exactly how to use a cock like that? Who knows how to breed you? I’d lie in the clinic on the moon, my belly starting to swell with his child, and I’d touch myself, thinking about that curve, that vein, the way his balls would slap against me...”

Kichijō couldn’t take it anymore. She moved, rolling to straddle Osa’s thigh, grinding her own slick cunt against the firm muscle. “Keep talking, ” she demanded, her voice rough.

Osa’s story was doing more than just arousing them; it was a blueprint. A revelation. Her petite frame, her neat, delicate pussy that was now so obviously hungry for immense, stretching girth. She was a converted size queen, and she was converting them with every word.

“On birth control, after the baby, the fucking was... recreational. Amazing, but different. But that first two weeks... that was purposeful. That was him trying to put a baby so deep inside me that nothing could stop it.” Osa’s breathing grew ragged as her fingers worked faster. “And when I was on the moon, feeling the first flutters of life he’d put in me... I’d dream of his cock. I’d fantasize about it being even bigger. Impossible bigger. Like Vas’s.”

Olanke’s hand joined Osa’s, her larger blue fingers covering Osa’s smaller dark ones, pushing them deeper inside Osa’s wet heat. “You want that now, ” Olanke stated, her voice a low thrum. “You want to be filled like that again.”

“Yes, ” Osa hissed, her back arching. “I want to be ruined. I want a cock so big it hurts in the best way. I want to feel that stretch for days after. I want to be drowned in cum.”

Kichijō leaned down, capturing Osa’s lips in a searing, sensual kiss. It was deep and consuming, all tongue and shared breath. When she broke away, she was panting. “We don’t have a Vas on board, ” she murmured against Osa’s mouth. “But we have hands. And mouths. And I have an idea.”

She shifted off Osa and moved to the small locker at the foot of the bunk. From it, she retrieved the Telchine dildo from their earlier play. It was still slick from earlier use, a thick, imposing length of shimmering, semi-rigid flesh.

Osa’s eyes locked on it, a fresh wave of want soaking her thighs. “That.”

“This, ” Kichijō agreed, crawling back onto the bunk. She positioned herself between Osa’s spread legs, the toy in hand. Olanke moved to support Osa’s head in her lap, her blue hands coming to cup Osa’s small, pert breasts, thumbs circling her pierced nipples.

Kichijō didn’t just push it in. She teased. She used the broad, flared head of the dildo to paint slow, wet circles around Osa’s entrance, spreading her own abundant arousal. Osa’s pussy glistened, her delicate, dark lips already puffy and flared from earlier, the pierced nub of her clit fully exposed and throbbing.

“Please, ” Osa begged, the word a breathy moan.

“Tell me what you want, ” Kichijō demanded, pressing the tip just slightly against the tight ring of muscle.

“I want you to fuck me with it. I want you to make me take it, like he did. Slow at first. I want to feel every fucking inch.”

Kichijō applied pressure. A gentle, rhythmic nudging. Osa’s body yielded, the tight entrance granting a millimeter, then two. The head, nearly as wide as Vas’s had been, began to sink in. A low, guttural moan tore from Osa’s throat. The stretch was immediate, exquisite. Kichijō pulled back, letting Osa’s pussy cling to the toy, the stretched orifice slowly trying to close.

Then she pressed again, a little deeper this time. The wet, schlicking sound was obscenely loud in the quiet room. In, out. Deeper each time. Osa’s hands fisted in the sheets, her hips lifting to meet each gentle invasion. Olanke pinched her nipples, rolling the metal bars between her fingers, sending jolts of pleasure-pain straight to Osa’s core.

“It’s so... big, ” Osa panted, her eyes squeezed shut. “It’s stretching me so good. Don’t stop. Fuck, don’t you dare stop.”

Kichijō complied, her own cunt aching with sympathy. She watched, mesmerized, as Osa’s tight little hole was slowly, meticulously conquered by the girthy toy. With each withdrawal, it glistened, coated in Osa’s creamy wetness. With each deeper penetration, Osa’s body trembled, her inner muscles fluttering around the invading shaft.

Finally, the final, thickest part of the toy slipped past her entrance with a wet, sucking pop. Kichijō hilted it, the base pressing firmly against Osa’s swollen lips and clit. Osa screamed, a sound of pure, unadulterated relief. She was full. Punishingly full.

“Now fuck me, ” Osa begged, her voice cracking. “Fuck me with it. Make me come on this fake cock. I need it. I need to feel like I’m being bred.”

Kichijō began to move.
