Sally cornered Marie the next morning by the coffee machine. Marie stiffened, clutching her mug like a shield. “We need to talk about Helen and Lydia,” Sally announced, her voice honey-sweet but edged with steel. “Veronica’s thirteen now, right? A swimming prodigy. And Brianna—fifteen, cheer captain.” Marie’s knuckles whitened. “They’re children, Sally! Innocent!” Sally’s smile didn’t reach her eyes. “Innocence is overrated. Frank needs ... variety. Fresh blood to breed.” She leaned closer. “Think of the dynasty. His seed deserves the tightest, youngest cunts.” Marie recoiled. “You’re monstrous.” Sally shrugged. “I’m practical. And Frank agrees.”
Frank entered the kitchen, his presence silencing Marie’s protest. “Problem?” he asked, his gaze fixed on Sally. Marie spun to face him, desperation in her voice. “Frank, please! Don’t involve my nieces. They’re not like us—” Frank cut her off with a raised hand. “They’ll learn.” His tone brooked no argument. “Call Helen and Lydia. Arrange for Veronica and Brianna to spend the summer here.” Marie choked back a sob. Sally beamed. “Perfect. I’ll prepare the guest rooms ... close to ours.” Frank nodded, his eyes already distant, imagining the taste of untouched flesh. “Make sure they arrive by June first, that’s 2 weeks from now”
Marie’s hands trembled as she made a group WhatsApp call with her sister Helen and Lydia. “Helen? Lyida? It’s Marie...” Her voice cracked. Sally watched from the doorway, arms crossed, a predator’s patience in her stance. “How have you been? It’s been too long...” Marie forced a smile. Frank stood behind her, his presence a silent command. “We were thinking,” Marie continued, swallowing hard, “Veronica and Brianna should spend the summer with us. We’ve got the pool ... and Brianna could even help with cheer routines for Ava.”
Helen’s voice chirped through the speaker, oblivious. “Oh, Ronnie would love that! She just won regionals, you know.” Lydia chimed in, “Bri’s got nationals soon, but a break would do her good.” Marie’s knuckles whitened on the counter. “Perfect,” Frank interjected, his tone smooth as velvet. “We’ll expect them June first.” The call ended. Marie whirled around, eyes blazing. “They’re children, Frank! You can’t—” Sally stepped forward, cutting her off. “They’re family. And Frank deserves the tightest, purest cunts to breed.” She traced Frank’s jawline. “Veronica’s only thirteen. No period yet. Imagine breaking her in ... virgin blood on his cock.” Marie gagged. Frank gripped Marie’s chin, his thumb pressing into her pulse point. “Make the arrangements. Or shall I remind how you were the instigator who suggested Ava for your desire to have more kids.” Marie slumped, defeated. “Fine. I’ll book their flights.”
Later, Sally knelt before Frank in their bedroom, his cock heavy on her tongue. “They’ll arrive innocent,” she murmured between slow, worshipful sucks. “But Veronica...” She hollowed her cheeks, drawing a groan from him. “We’ll take her swimming. Get her alone.” Frank tangled his fingers in her hair, guiding her deeper. “And Brianna?” Sally pulled off, a slick strand connecting her lips to his tip. “Cheer practice. I’ll ‘spot’ her.” Her hand pumped his shaft. “Bend her over the mats. Let her feel your thickness before you even fuck her.” Frank’s hips jerked. “Yes.” Sally smiled, returning to her task with fervor. “I’ll prepare them for you, husband. Open them up ... so you can plant your seed right in their untouched wombs.”
The door creaked open. Janet stood there, belly enormous, her eyes dark with fury. “Planning to defile children now?” Sally didn’t pause, her mouth working Frank’s cock with obscene wet sounds. Frank met Janet’s glare. “Jealous?” Janet’s fists clenched. “They’re babies.” Sally pulled off with a pop. “And soon they’ll be mothers. Of Frank’s blood.” She nuzzled his balls. “Just like you were at seventeen, Janet. Or did you forget?” Janet’s face paled. Frank gestured her closer. “Suck her clit while Sally finishes me. Remind yourself who owns you.” Janet hesitated, then shuffled forward, lowering herself awkwardly beside Sally. As Sally took Frank back into her throat, Janet’s tongue flicked Sally’s swollen bud—a bitter servant to the dynasty. Frank’s groan echoed in the room. Breeding season had begun.
June first dawned sticky and bright. Veronica bounded out of the taxi first, her swimmer’s frame lean in denim shorts, a backpack slung over one shoulder. Brianna followed, more reserved, her cheerleader posture perfect even after the flight. Marie enveloped them in a hug that felt more like a cage, her lips brushing each niece’s cheek too quickly, too coldly. “Welcome home, darlings,” she murmured, her voice strained. Frank stepped forward next. His hug crushed Veronica first, one large hand splayed low on her back, the other cupping the nape of her neck, lingering. Veronica stiffened, her bright smile faltering. Brianna got the same treatment—Frank’s arms like steel bands, his face buried in her hair, inhaling deeply as his hands slid down to grip her waist, thumbs pressing just above her hip bones. Brianna pulled back first, eyes wide with discomfort. “Uncle Frank,” she breathed, flustered.
Inside, the house buzzed with chaotic warmth—Ava shushing a crying toddler, Sara jiggling her baby boy on her hip. Marie gestured toward the stairs. “Sleeping’s tight. Veronica, you’re with me. Ava’s in the nursery with the little ones. Sara’s in the guest room with baby Michael.” She avoided Brianna’s questioning gaze. “That leaves ... the study’s pull-out for you, Brianna. Frank will be in there too—it’s his office, but he’ll sleep on the sofa bed.” Brianna’s cheeks flushed crimson. “Share a room? With Uncle Frank? Aunt Marie, that’s ... I’m fifteen!” Marie busied herself with a teacup. “Just for a few nights, sweetheart. We’re full up.” Brianna’s voice rose, sharp with panic. “Can’t I sleep on the living room couch? Or with Veronica?” Frank appeared in the doorway, his presence silencing the room. “The study’s comfortable,” he stated, his tone leaving no room for argument. “You’ll be fine, Brianna.” His eyes traced her figure, slow and assessing. Brianna shivered.
The first two nights passed in tense silence. Brianna curled rigidly on her pull-out, her back to Frank. She barely slept, listening to his steady breathing, flinching at every rustle of sheets. Twice, deep in the night, she heard the soft click of the door. Frank slipped out—silent, predatory. She lay frozen, heart hammering, until he returned much later, smelling faintly of sweat and Ava’s perfume. He didn’t touch her. Just slid onto his pull-out bed, his breathing deepening almost instantly. Relief warred with a strange, gnawing unease. What was he doing? Where did he go? She dared not ask.
On the third night, exhaustion finally claimed her. Sometime near dawn, Brianna stirred, blinking in the grey pre-light filtering through the study curtains. She rolled over—and froze. Frank lay on his back, completely nude. The sheet pooled low on his hips, exposing the thick, heavy length of his flaccid cock resting against his thigh. Even soft, it was shockingly large—a monstrous, veined thing Brianna had never imagined possible. Her breath hitched, a choked gasp escaping her lips. Her eyes widened, glued to it, unable to look away. Heat flooded her cheeks, a confusing mix of terror and something else—fascination? Disgust? Her pulse roared in her ears.
Frank didn’t stir. He seemed deeply asleep, oblivious. Brianna squeezed her eyes shut, rolling violently back to her side, trembling. She pulled the thin blanket over her head, trying to erase the image burned into her mind. But it was impossible. The sheer size of him, the casual power in his nakedness ... It felt like a violation just seeing it. She lay rigid, heart pounding, wondering what kind of man her uncle truly was—and why the sight of him filled her with such paralyzing dread.
The next morning, Frank announced the pull-out couch Brianna slept on was broken. He showed her the bent frame and torn fabric near the hinges, shrugging. “Must have happened last night,” he said, his expression bland. “You’ll have to sleep in my bed tonight, Brianna. It’s large enough.” Brianna’s stomach dropped. “No! I’ll sleep on the floor!” Frank’s gaze hardened. “Don’t be ridiculous. It’s just sleeping.” Veronica shot her a sympathetic glance but said nothing, relieved her own bed beside Marie remained untouched. Brianna fled to the bathroom, locking the door. She pulled out her phone, hands shaking as she dialed her mom. “Mom, please,” she whispered, voice thick with panic. “Uncle Frank wants me to sleep in his bed. The couch broke. And ... Mom, he’s huge. Like a monster. I saw him naked! I’m scared!”
