The cult chamber smelled of incense and candle smoke. Three robed leaders sat behind the obsidian table, their faces half-hidden in shadow. Sophie stood opposite them, arms folded, waiting.

One leader spoke first. “Sales of Futanari seed have dropped. Fewer women request direct impregnation. We need variety—different ethnic backgrounds—to bring demand back.”

Sophie raised an eyebrow. “And what exactly do you expect me to do?”

“We know a Futanari child only forms when the partners share a deep emotional bond,” the second leader said. “That is why we have chosen Chloe to impregnate Issabell.”

Sophie’s eyes narrowed. “Issa is Chloe’s half-sister. Rachel’s daughter from one of her ritual pregnancies. You’re asking for incest.”

The third leader answered without hesitation. “It is necessary. A Futanari nation cannot be built on a single bloodline.”

They ended the meeting with the secret salute: two quick strokes at groin height, as if stroking an invisible cock.


Sophie found Chloe curled up on her bed with a book. The girl looked up, cheeks already pink.

“I have a surprise,” Sophie said. “You and Issa are going to have a sleepover. Just the two of you, here in your room. Games, snacks, staying up late—then you sleep in the same bed.”

Chloe’s eyes widened. “Really? All night?”

“All night,” Sophie confirmed.

Chloe bounced on the mattress, beaming.


The first sleepover ended with both girls tangled under the covers. Chloe lay rigid, her massive cock throbbing against her thigh, refusing to soften. Every tiny shift of Issa’s body made it worse.

Issa stirred. In the dark she whispered, “You are hard, aren’t you? I can feel it pressing against my leg.”

Chloe swallowed. “Yeah. Sorry. It just won’t go down.”

“I can help,” Issa offered, voice small. “If you want me to.”

Chloe hesitated, then nodded.

She pushed her pajama pants down. Her cock sprang free, heavy and veined, the head already glistening with precum. Issa’s fingers wrapped around the thick shaft and began a slow, careful stroke.

“It’s so warm,” Issa murmured, her thumb brushing over the sensitive head. “And it’s getting bigger in my hand. Does that feel good when I touch you here?”

Chloe bit her lip, hips twitching. “Y-yeah… really good.”

Issa kept the rhythm steady, her grip firm but gentle. “Tell me what you like. Do you want me to go faster?”

“A little,” Chloe breathed. “Please.”

Issa increased the pace, her small hand sliding up and down the massive length. Chloe’s breathing grew ragged, her balls tightening as the pleasure built.

“I’m close,” Chloe gasped. “Issa, I’m going to—”

Thick ropes of cum splattered across the wooden floor, pulse after pulse erupting from Chloe’s cock. Issa kept stroking through the orgasm, milking every drop until Chloe’s shaft finally began to soften.

They fell asleep with the scent of sex in the air.


On the sixth sleepover, the girls lay facing each other after the lights were out.

“My body is weird,” Chloe mumbled. “This huge cock… nobody will ever want me.”

Issa’s voice was barely audible. “I am chubby. Small tits, fat ass. Same problem.”

Silence stretched, then Chloe reached out and touched Issa’s cheek. “I like how you look. Your curves are soft and warm.”

Issa’s eyes shone. “I like your cock. It’s big and strong and it makes me feel… wanted.”

They kissed—soft at first, then deeper. Clothes came off. Hands explored. Chloe’s fingers sank into Issa’s plush ass while Issa stroked the heavy length between her thighs.

“Can I taste you?” Issa asked, her voice trembling with desire.

Chloe nodded, her face flushed. “Please.”

Issa moved down between Chloe’s legs, her tongue tentatively licking the head of Chloe’s cock. “Mmm, it tastes salty and sweet at the same time,” she murmured before taking the head into her mouth.

Chloe gasped, her hips bucking slightly. “Issa… that feels amazing.”

Issa took more of the thick shaft into her mouth, her tongue swirling around the head while her hand stroked the base. She bobbed her head slowly, taking Chloe deeper with each movement.

“Your mouth is so warm,” Chloe moaned, her fingers tangling in Issa’s hair. “I’m getting so hard.”

Issa pulled back, saliva connecting her lips to Chloe’s cock. “I want you inside me,” she whispered. “I want to feel you stretching me open.”

Chloe climbed on top, her cock nudging against Issa’s wet entrance. “Are you sure?” she asked, her voice shaking.

“Yes,” Issa breathed. “I want this. I want you.”

Chloe pushed forward slowly, the head of her cock parting Issa’s folds. Inch by inch she sank into the tight, wet heat, both girls moaning as they joined.

“You’re so tight,” Chloe gasped, her hips stilling when she was fully buried inside Issa.

“You’re so big,” Issa whimpered, her legs wrapping around Chloe’s waist. “I can feel you everywhere.”

They moved together, breathing the same air. Chloe’s rhythm was slow and careful at first, each thrust drawing soft sounds from Issa’s throat.

“Faster,” Issa begged, her nails digging into Chloe’s back. “I want to feel you pounding into me.”

Chloe increased her pace, her hips slapping against Issa’s ass with each thrust. The wet sound of their joining filled the room, punctuated by their moans and gasps.

“Right there,” Issa cried out, her body arching. “Don’t stop, Chloe. Please don’t stop.”

Chloe’s rhythm faltered. The words burst out before she could stop them. “Issa, I love you. I love you so much.”

Issa’s legs tightened around her. “I love you too, Chloe. I’ve loved you for so long.”

Chloe’s heart slammed against her ribs. Her balls drew up hard. She pushed deep and came in long, pulsing surges, flooding Issa’s womb with hot, thick seed.

“I can feel it,” Issa moaned, her own orgasm washing over her. “You’re filling me up. So much cum…”

They fell asleep still joined, naked and clinging to each other, Chloe’s cock still twitching inside Issa’s cum-filled pussy.

By morning, Chloe’s seed had taken root. A new Futanari grew inside Issa’s belly.
