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.
