A heavy silence filled the house, the tension from dinner still hanging thick in the air. Owen sat on his bed, a comic book forgotten in his hands. He replayed the scene in his mind: Dom pushing his plate away in disgust. “This is the same shit you made last night.” Mia’s sharp, wavering reply: “I told you what we needed. You forgot half the list.” Dom’s eyes darkening. “Watch your mouth, girl. You’re lucky I’m putting food on this table. Ungrateful little brat.” The suffocating silence that had consumed the rest of the meal. Owen had done nothing. His silence had been a green light. And now, upstairs, Mia was paying the price.
Upstairs, a loud crash shattered the quiet, followed by Mia’s muffled cry. Dom’s booming voice, rough and cruel, echoed down the hallway. “That sharp little tongue of yours is going to get you in real trouble.”
Owen’s heart hammered against his ribs. It had started.
He stood, his legs leaden, and crept to his door. He was scrawny, trembling. Dom was a mountain of muscle and rage. But the sound of Mia’s sobs cut through his fear. He couldn’t just stand there. Not again.
Owen pressed his eye to the crack in Dom’s bedroom door. The room was oppressive, reeking of sweat and musk. A single bulb cast flickering shadows on the walls. Mia stood trembling in her thin yellow nightgown, the damp fabric clinging to her body, outlining her small, perky breasts and the gentle curve of her hips. Her hands were clasped tightly in front of her, her face pale with terror.
Dom loomed over her, a white undershirt stretched tight across his broad chest, sweatpants tented obscenely at the front. He circled her, his boots thudding on the floor.
“Uncle Dom, please,” Mia pleaded, her voice trembling. “I didn’t mean to upset you. I’ll do better.”
A low, menacing chuckle escaped Dom. “You’ve got your mom’s mouth. Always talking back.” His hand shot out with surprising speed, clamping around her wrist. “But I fixed that. Taught her how to keep that pretty little mouth busy.”
Mia gasped, trying to pull away. “Stop!”
He threw her onto the tangled, stained sheets of the bed. She scrambled to sit up, but he was on her instantly, his massive frame pinning her down. As he grabbed the hem of her nightgown, ripping it upward, Owen burst into the room.
“Leave her alone!”
Dom paused, his hands gripping the torn fabric. He turned his head slowly, a smirk spreading across his face. “Well, well. Look who decided to join the party.”
A hot flush of humiliation spread across Mia’s cheeks as she tried to cover herself. “Owen, don’t—”
“No, no, sweetheart,” Dom interrupted, his voice dark. “Your brother’s here. He’s gonna learn what it means to be a man.” He released Mia and stood, his shadow swallowing Owen whole. Before Owen could react, Dom grabbed his arm with an iron grip and dragged him to a wooden chair in the corner.
“Sit down, boy.” Dom shoved Owen into the chair, knocking the wind from him. He produced a length of rough rope from a drawer and began tying him down. He looped it around Owen’s torso, pinning his arms, then lashed his ankles to the chair legs. The knots tightened with every struggle. Soon, Owen was utterly immobilized.
“That’s better,” Dom said, his voice thick with satisfaction. “Now you’re gonna watch. Learn what it means to be a man.”
Owen’s chest heaved as Dom turned back to Mia. She was sprawled on the bed, her nightgown torn off her shoulders, exposing her youthful frame. Her breasts were small and firm, her nipples a delicate pink, hardened from fear. Her stomach was flat, her waist narrow. Her white cotton panties were all that was left.
Dom grabbed her wrists, pinning them above her head with one hand. With the other, he yanked her panties down her legs. Mia whimpered, left completely exposed, the sparse tuft of light brown hair above her delicate pussy emphasizing her vulnerability.
“Uncle Dom, please,” she sobbed. “I’ll do anything.”
“You’re gonna do more than anything,” he growled, his breath hot against her ear. “You’re going to take every inch of me, and you’re going to thank me for it.” His eyes raked over her naked body. “You’re filling out nicely. Just like your mom did.” He leaned back, his gaze cruel. “Now, let’s see if you’ve got your mom’s tight little cunt too.”
His hand moved down her body. Mia let out a choked sob.
“Eyes front and center, boy,” Dom commanded without looking back. “You’re gonna watch this.”
Dom gripped Mia’s thighs, spreading them apart with brutal force. A shudder of tension locked her muscles, her hands clawing at the sheets. Her small, delicate pussy glistened, trembling. The contrast was obscene—his monstrous, veiny cock poised to invade her untouched body.
He pressed the swollen, purple head against her virgin entrance, the sheer size of it a grotesque mismatch for her small body. Mia let out a sharp, panicked cry. “Stop! Please, it’s too much! You’ll tear me!” He ignored her, pushing forward. The thick, unforgiving head stretched her impossibly tight opening, the flesh burning and threatening to split. She screamed, a raw sound of agony, her body arching off the bed.
Dom groaned, savoring the intense resistance. “Fuck, you’re tight.” He pushed deeper, the thick veins of his shaft rubbing against her delicate inner walls.
With a brutal thrust, he ripped through her hymen. A bloodcurdling scream tore from Mia’s throat as white-hot agony convulsed her frame. Her fingernails dug into his arms.
He paused, buried inside her, his breath hot against her ear. “Your mom screamed just like you,” he rasped. “But by the time I was done, she didn’t want me to stop. You won’t either.”
He began to move, slow and deliberate. The wet, squelching sounds filled the room, mingling with Mia’s sobs and Dom’s grunts. Her inner walls clenched instinctively, trying to push him out.
From his forced vantage point, Owen saw the horrific sight of her violated body stretched around Dom’s monstrous cock, a stark reminder of their helplessness.
Dom’s thrusts grew deeper, pressing against her cervix. Mia cried out. “No, please, it’s too deep! It hurts!”
“You’ll get used to it,” he growled, gripping her hips, pulling her onto his cock with each thrust. “Your body will learn to love it.”
Dom’s massive cock, glistening with a mix of her wetness and the blood from her torn hymen, pistoned in and out of her. She jerked with each brutal movement, her small breasts bouncing, her legs splayed open, her feet brushing the floor. The wet, slapping sounds were a sickening symphony.
From his chair, Owen had a clear, horrific view. He saw the way her pussy lips clung to his shaft, the way her body was dominated by his bulk.
“Look at that,” Dom growled, leaning back to watch himself enter her. “It’s barely big enough for me. But it’s trying so hard. Fuck, you feel amazing.”
Mia sobbed, her body a puppet to his violence.
Then, Owen saw her body stiffen for a different reason. Her choked sobs faltered, replaced by a sharp, ragged gasp. Her hips, which had been rigid with resistance, gave a tiny, involuntary twitch.
Dom noticed immediately. “Feel that?” he grunted, thrusting deeper as her body responded. “You can say no, but your pussy’s saying yes.”
“Stop,” Mia whimpered, shaking her head, fighting the sensations.
But her body refused to listen. The warmth intensified. Her hips twitched involuntarily. Her pussy clenched tighter around him, trying to pull him deeper.
A dark chuckle rumbled in Dom’s chest. “That’s it. Your body knows what it needs. You hate me, but your cunt loves this cock.”
She shook her head, tears streaming. She fought the sensations, clinging to the pain, but the pleasure was insidious, undeniable. She hated herself for it.
His thrusts grew more deliberate. “That’s it. Let go. You’re mine now. Your body knows it.”
She tried to lock herself away, but the warmth spread like poison. Her pussy betrayed her again, clenching around him. She hated the way her hips twitched, craving more of the violation.
“Fight it all you want,” he breathed in her ear. “Doesn’t change a thing. You’re mine now.”
“No ... I’m just a kid ... please, no...” she sobbed, the words dissolving into incoherent pleas.
Her protests were hollow. The pleasure intensified, mingling with the pain. Her legs trembled, toes curling.
“Shh. Don’t fight it. Look at you—so tight, so wet. You hate me, but your pussy loves me.”
Owen saw her hips move against her will, a frantic, jerking motion that seemed to pull Dom deeper. He saw the look of pure self-loathing that contorted her face. She wasn’t ready for this. Her immaturity made it more devastating.
