Lily’s eyes darted between Ross and Thor, the dog panting and circling, his large, rock-hard cock swinging red and urgent between his hind legs. With a final bite of her lip, her gaze focused back on Ross, dark and unwavering. “Daddy?” she breathed, the word a hot whisper in the thick air. “I want you to help me try something.”

She didn’t wait. Her hands went to the hem of her tank top, pulling it over her head in one fluid motion, letting it drop to the floor. Her sleep shorts followed, kicked aside, and then she was just standing there, naked in the lamplight. Fifteen years old, all smooth skin and sharp angles, her small breasts tipped with tight, pink nipples. Her pussy glistened, dripping wet, a blatant invitation. Ross’s breath hitched, a raw sound torn from his chest. She stepped closer, placing her small hand over the one he had clenched on the arm of the chair. “He’s so big,” she whispered, nodding toward Thor, who whined and nudged her bare thigh with his wet nose. “I want to feel it. I want you to help him fill me up.” Her other hand trailed down Ross’s bare chest, over the tense ridges of his abdomen, until her fingers brushed the weeping head of his own cock. “You can watch. You can hold me. And then… then he can have you, too. I want to see that.”

Ross was wrecked. His conscience was a distant scream, drowned out by the pounding of his blood and the sight of her, so young and so hungry, begging for this corruption. His control, so carefully maintained for years, was ash. A low groan escaped him as her fingers curled around his length, stroking once, claiming him. “Lily,” he managed, his voice shattered. “Jesus Christ.”

“It’s okay,” she murmured, guiding his hand from the chair to her hip, her skin fever-hot under his calloused palm. She turned, presenting herself to the anxious dog, and used Ross’s hand to pull herself into a position, bending over, her back arched, her dripping cunt exposed. “Help him, daddy. Show him where to go.” Thor needed no further encouragement, his instincts overpowering. He mounted her in a single, clumsy lunge, his front paws scrabbling for purchase on her slender back. Ross watched, hypnotized, as the dog’s huge, tapered cock found her slick entrance, nudging against it. Lily gasped, her body jolting. “Hold me,” she pleaded, and Ross’s other arm came around her front, pinning her against him, feeling her heart hammer against his forearm.

With a grunt and a powerful thrust of his hips, Thor pushed inside. Lily cried out, a sharp, broken sound that wasn’t pain but shock at the stretch, the incredible, burning fullness. Ross felt it through her body, the invasion, the dog’s thick length burying itself deep into her young pussy. He watched, his own cock throbbing painfully, as Thor began to fuck her in earnest, a rapid, animal rhythm, the wet, slapping sounds obscene in the quiet room. Lily’s head fell back against Ross’s shoulder, her eyes squeezed shut, her mouth open on silent, ragged breaths. “He’s… he’s so deep,” she whimpered, her nails digging into the arm wrapped around her. “Daddy… I can feel him… everywhere.”

The dog’s pace became frantic, his panting turning to sharp, huffing grunts. Ross knew the signs. He tightened his hold on Lily, bracing her. “He’s gonna come,” Ross growled into her ear, the words filthy and true. Thor’s thrusts lost rhythm, becoming jerky, desperate pulses, and then he stilled, buried to the hilt, a long, shuddering whine tearing from his throat. Lily felt it—the hot, sudden flood filling her, pumping deep into her womb. She moaned, a low, continuous sound of overwhelmed sensation, her body clenching around the spurting cock. Ross held her through it, feeling the tremors that wracked her slight frame, watching the dog finally slump off her, his cock sliding out with a wet, final pop.

Lily turned in his arms, her body slick with sweat and the dog’s release. She pressed her forehead against Ross’s, her breath coming in hot, shallow puffs. “Your turn,” she whispered, the words a dark promise. Her small hand slid down his chest, over the tense plane of his stomach, and wrapped around his aching cock. She stroked him slowly, her thumb smearing the bead of precum over his sensitive head. “I want to watch him fill you up, daddy. I want to see you take it.”

Ross couldn’t speak. The animal heat of her, the smell of sex and dog and salt filled his lungs. Her eyes held his, unblinking, and in them he saw no shame, only a fierce, triumphant hunger. She guided his hand behind him, pressing his own palm against the small of his back. “Bend over the chair,” she murmured, her lips brushing his. “For me.”

The command unspooled the last thread of his resistance. He moved mechanically, turning from her, his builder’s hands gripping the worn velvet of the armchair. He bent, presenting himself, the cool air of the room a shock against his exposed skin. He heard Thor’s panting, the click of nails on hardwood as the dog circled, scenting the new opportunity. Lily’s hands were on his hips, her touch possessive. “He’s ready for you,” she said, her voice thick with arousal. “Just like I was.”

Ross felt the dog’s wet nose nudge against his inner thigh, then the blunt, insistent pressure of Thor’s cock against his entrance. He gritted his teeth, a low groan vibrating in his chest. Lily’s fingers dug into his hips, holding him steady. “Let him in,” she breathed, and it was her voice, her want, that made him relent, that made his body go slack with surrender. Thor pushed, and the stretch was immediate, burning, an impossible fullness that stole the air from Ross’s lungs. He dropped his forehead to the chair back, a strangled sound escaping him as the dog sheathed himself completely inside him.

The rhythm was brutal, instinctual. Each thrust drove Ross forward, the chair scraping against the floor with the force. Lily watched, her hand moving between her own legs, her fingers sliding through her wetness as she witnessed the animal taking her stepfather. Ross’s knuckles were white where he gripped the fabric, every muscle corded with strain and shocking, degrading pleasure. Thor’s panting became ragged, his thrusts turning jerky and deep. Ross felt the moment change, the dog’s cock swelling, pulsing inside him. “He’s gonna come,” Lily gasped, her own breathing frantic. “Take it, daddy. Take all of it.”

The orgasm ripped through the animal, a series of violent shudders. Ross felt the hot, liquid flood erupting deep inside him, filling him, a claiming that was both violation and absolution. A raw, broken noise was torn from his throat, his own untouched cock throbbing painfully between his legs. Thor slumped against him, spent, before withdrawing with a wet, final sound. Ross stayed bent over the chair, emptied and full, the dog’s seed already leaking down his thighs. Lily’s cool hand touched the small of his back, her fingers tracing the sweat there. She said nothing. She just watched.
