Emma stood outside her father’s study, her heart pounding in her chest. She clutched the list of ground rules she’d scribbled down, her hands trembling slightly. Taking a deep breath, she knocked on the door, the sound echoing in the quiet hallway.
“Come in,” her father’s voice called from inside. Emma pushed the door open and stepped into the room. Her father sat at his desk, his broad frame silhouetted by the soft glow of the desk lamp. He looked up as she entered, his expression unreadable.
“Dad,” she began, her voice slightly shaky. “I’ve ... I’ve made a decision.”
Her father leaned back in his chair, his eyes narrowing slightly. “And?”
Emma swallowed hard, forcing herself to maintain eye contact. “I’ll do it. But we need to set some ground rules. I need to feel like I have some control over this.”
Her father’s lips curved into a faint, almost imperceptible smile. “Alright,” he said, his tone deceptively calm. “Let’s hear them.”
Emma took a deep breath, her voice trembling as she began. “First, it has to be ... clinical. Just about the act itself. No kissing, no cuddling. I can’t ... I can’t handle it being anything else.”
Her father’s smile widened, his eyes glinting with something that made Emma’s stomach churn. “Clinical, huh?” he said, his voice low and smooth. “Emma, I appreciate your ... pragmatism. But there are things about sex—about conception—that you don’t understand yet.”
She shook her head, her cheeks flushing with embarrassment and anger. “I don’t care about positions or techniques. I just ... I just want to get it over with.”
Her father chuckled softly, leaning forward in his chair. “It’s not that simple, sweetheart. Conception isn’t always guaranteed the first time. We might need to try different ... approaches to make sure it takes. And some of them might feel ... uncomfortable at first. But I’ll guide you through it. You’ll see.”
Emma’s stomach twisted at the implication. She hadn’t considered the possibility of it happening more than once, or that her father might push for more than she was willing to give. “I ... I just want it to be quick,” she said, her voice barely above a whisper.
Her father nodded, his expression softening, though his eyes still held that unsettling intensity. “I understand. But we have to be realistic about this. If it doesn’t work the first time, we’ll need to try again. And who knows? You might end up ... enjoying it. We should keep an open mind.”
Emma’s face burned at the suggestion, her body tense with a mix of fear and shame. She hated the way he looked at her, the way his eyes seemed to linger on her body, as if already imagining what she would look like beneath him.
“It ... it should be in my room,” Emma said finally, her voice trembling. “I need to feel ... safe.”
Her father raised an eyebrow, a sly smile tugging at the corners of his lips. “Your room, huh? Alright. We’ll make it comfortable for you. But Emma, you have to understand ... this isn’t going to be easy for me either. I’ll need to ... prepare you. Make sure you’re ready.”
Emma’s face burned at the implication, her body tense with a mix of fear and shame. She hated the way he looked at her, the way his eyes seemed to linger on her body, as if already imagining what she would look like beneath him. “I ... I’ll be ready,” she said, her voice barely audible.
Her father smirked, leaning back in his chair. “Good. Because it’s going to be a lot for you to handle your first time.”
Emma’s breath hitched, her mind conjuring images she didn’t want to acknowledge. She’d overheard her friends talking about their dads once, their voices hushed and giggly, as they lounged by the pool during one of their summer hangouts.
“Emma’s dad is, like, huge,” Sophia had said, her voice dripping with awe.
“I know, right?” Olivia had chimed in, blushing furiously. “I mean, you can’t not notice. He’s always wearing those tight swim trunks, and it’s just ... there. Like, front and center.”
Amy had giggled, covering her mouth with her hand. “I don’t know how Emma doesn’t die of embarrassment. I’d never be able to look my dad in the eye if I were her.”
Emma had pretended not to hear, her cheeks burning as she focused on the pool float she was inflating, but their words had stuck with her. She’d noticed it too, of course—how could she not? Her father was always casual, almost careless, about his body. He’d lounge by the pool in his snug swim trunks, his muscular frame on full display, and Emma would catch herself glancing at the prominent bulge that always seemed too there. She’d look away quickly, her heart racing, but the image would linger, haunting her thoughts long after he’d left.
Now, as she stood in his study, the memory of those summer days felt like a cruel joke.
Her father leaned forward, his voice dropping to a low, almost intimate tone. “You know, I’ve always been ... generous in that department. It’s going to be a lot for you to handle your first time. I’ll go slow, but ... it’s going to stretch you. You might feel some discomfort.”
Emma’s breath hitched, her mind conjuring vivid images—his thick cock, the sheer size of it, the way it might feel to stretch her wide, to fill her completely. The thought made her stomach twist with a mix of revulsion and something else—something she didn’t want to name.
“I ... I’ll manage,” she whispered, her voice trembling.
Her father chuckled, a dark, predatory sound. “That’s my girl. You’re stronger than you think. And trust me ... once you’re used to it, you’ll see why women can’t get enough of a man like me.”
Emma’s stomach churned at the words, but she forced herself to nod. She hated herself for agreeing to this, for letting him talk to her like this, but she knew she had no choice. She had to do this—for her mother, for her family.
Her father stood, his towering frame looming over her as he placed a hand on her shoulder. “I’ll take care of you, Emma. You won’t regret this. When should we start?”
Emma swallowed hard, her body trembling with a mix of fear and anticipation. “Tomorrow night,” she said, her voice barely audible. “After Mom’s asleep.”
Her father nodded, his smile widening. “Tomorrow night, then. I’ll make sure to ... prepare you properly.”
Emma nodded, her heart pounding in her chest as she turned and walked out of the room. She felt dirty, tainted, as if she’d just made a deal with the devil. But she knew there was no turning back now. She had to do this—for her family, for her mother.
But as she climbed the stairs to her room, the image of her father’s thick cock filling her virgin pussy lingered in her mind, a dark, forbidden fantasy that both repulsed and aroused her. She hated herself for it, but it was there, undeniable and insistent.
Emma sat on the edge of her bed, her heart pounding so loudly she was sure it could be heard down the hall. She’d changed into a soft nightgown, the fabric clinging to her trembling frame. Her mind was a whirlwind of conflicting emotions—fear, shame, and a perverse curiosity that she couldn’t quite suppress.
A soft knock on her door made her jump. “Come in,” she whispered, her voice barely audible.
The door creaked open, and her father stepped inside, closing it quietly behind him. He was shirtless, his muscular chest and broad shoulders on full display. Emma’s breath hitched as her eyes traveled lower, taking in the thick bulge straining against his sweatpants.
He approached the bed slowly, his eyes never leaving hers. “Are you ready?” he asked, his voice low and thick with an intensity that made her skin prickle.
She nodded, though her entire body was trembling. “I ... I think so.”
He sat down beside her, the mattress dipping under his weight. “You’re nervous,” he observed, his tone almost tender. “That’s natural. But I’ll take care of you, Emma. I promise.”
She nodded again, her throat too tight to speak. His fingers brushed against her cheek, and she flinched at the contact. “Relax,” he murmured. “I’m not going to hurt you. Not more than I have to.”
His words did little to ease her anxiety. She closed her eyes, trying to focus on anything but the size of him, the way his erection strained against his pants, and the terrifying prospect of trying to take something so large inside her.
A warm hand slid to her thigh, and Emma’s breath caught in her throat. “We’ll go slow,” he said, his voice a low rumble. “But I need you to trust me, Emma. Can you do that?”
She opened her eyes, meeting his gaze, and nodded despite the fear gripping her. “I’ll try.”
He leaned in, his lips brushing against her ear. “Good girl,” he whispered, his breath hot against her skin. “Now, lie back for me.”
Emma obeyed, her body stiff as she lay back against the pillows. Her father’s hands moved to the hem of her nightgown, lifting it slowly up her legs. She felt exposed, vulnerable, and she had to fight the urge to cover herself as he revealed her bare skin inch by inch.
“So beautiful,” he murmured, his voice thick with lust. “You have no idea how long I’ve waited for this.”
His hands moved to her thighs, gently spreading them apart. Emma’s breath hitched as she felt the cool air against her exposed skin. Her body was slender, her breasts small but pert, her nipples hardening under his gaze despite her shame. Her pussy was bare, smooth and hairless, a detail she hadn’t even thought to control but now felt excruciatingly exposed by.
“Shaved,” her father murmured, his voice thick with approval. “So soft ... so perfect.”
Emma’s face burned as his fingers traced closer to her core. She could feel herself betraying her own disgust, a slick warmth pooling between her legs as his touch sparked an unwanted response.
“You’re wet,” he observed, his voice low and rough with arousal. “Your body knows what it wants, even if you don’t.”
Her cheeks flushed with shame, but she couldn’t deny the truth in his words. His fingers brushed against her entrance, and she flinched at the intrusion.
“Shh,” he soothed, his thumb brushing against her clit in a way that made her gasp. “Just relax, Emma. Let me prepare you.”
She nodded, her body trembling as he worked a finger inside her, stretching her tight, virgin walls. The sensation was foreign, uncomfortable, but not entirely unpleasant. His finger probed deeper, and Emma’s breath caught as he encountered the thin barrier of her hymen.
“There it is,” he murmured, his voice thick with a mix of awe and hunger. “Your hymen ... so delicate. So pure.”
Emma’s stomach churned at the way he said it, like he was savoring her untouched state. His finger teased the barrier, pressing against it gently, testing its resistance.
“You’ve never let anyone touch you here,” he said, his voice dark with satisfaction. “But now ... now it’s mine.”
