Knocking up my baby Grandaughter

Chapter Text

I never thought it would happen like this.

My name is Emily, and at 14, I was still figuring out who I was. Fresh out of grad school with a degree in literature that felt more like a fancy piece of paper than a future, I’d moved back into my childhood home after Mom left Dad for good two years ago. She’d said the spark had died years earlier, but Dad, strong, quiet, forty-eight-year-old Marcus, had just nodded, kissed her cheek, and watched her drive away. I stayed because he needed me. Or maybe I needed him. The house was too big, too empty, and the silence between us had started to feel like something alive.

It started with small things. Late-night talks on the couch after I’d come home from my part-time bookstore job, both of us in pajamas, wine glasses half-empty. He’d look at me sometimes - really look - and I’d feel my skin warm under his gaze. I told myself it was nothing. Fathers were supposed to look at their daughters with pride. But pride didn’t explain the way his eyes lingered on the curve of my hips when I stretched, or how my pulse quickened when his hand brushed mine reaching for the remote.

One rainy Thursday in October, everything shifted.

I’d come home soaked from a sudden downpour, my thin white blouse clinging to my breasts like a second skin. Dad was in the kitchen making dinner - pasta, the smell of garlic and olive oil filling the air. He turned when I walked in, and for a second his face went still.

“Jesus, Em,” he said, voice low. “You’re drenched.”

I laughed it off, peeling the wet fabric away from my body, but I could feel my nipples tightening against the cold cotton. His eyes dropped there for half a heartbeat before he looked away, jaw tight.

“Go change before you catch a cold,” he muttered.

But I didn’t. Instead I stepped closer, close enough to smell the faint salt of his skin under the cooking smells. “Dad… you’ve been looking at me differently lately.”He froze, wooden spoon halfway to the pot. “Emily.”

“I’m not a little girl anymore.” My voice shook, but I kept going. “I see the way you watch me. And… I like it.

”The spoon clattered into the sink. He turned fully toward me, eyes dark, chest rising fast. “You don’t know what you’re saying.”

“I do.” I reached up, fingers trembling as I traced the stubble on his jaw. “I’ve been thinking about it too. About you. About us.”For a long moment he just stared. Then something broke in him - years of restraint snapping like a frayed rope. His hand cupped the back of my neck, rough and warm, and he kissed me like a man drowning. Hard. Hungry. His tongue pushed into my mouth and I moaned into it, pressing my soaked body against his solid frame. He was already hard; I could feel the thick length of him against my stomach through his sweatpants.

We didn’t make it to the bedroom. He lifted me onto the kitchen counter, dishes rattling, and yanked my wet blouse open. Buttons pinged across the tile. His mouth found my breast, sucking hard enough to make me gasp, teeth grazing the sensitive peak while his hand shoved my skirt up and ripped my panties aside.

“Fuck, Em,” he growled against my skin. “You’re so wet already.”

I was. Soaking. I’d never been this turned on in my life. “Please, Dad… I need you inside me.

”He didn’t ask twice. He shoved his pants down just enough to free himself - thick, veined, the head already glistening - and pushed into me in one long stroke. I cried out at the stretch, nails digging into his shoulders. He was bigger than anyone I’d ever been with, filling me completely, the slight burn only making it hotter.

He fucked me right there on the counter, hard and deep, one hand tangled in my damp hair, the other gripping my ass to pull me onto him. The sound of skin slapping skin mixed with my moans and his ragged breathing. Every thrust hit that perfect spot inside me until I was shaking, clenching around him.

“Gonna come,” I whimpered. “Dad - oh god - ”

“Come on my cock, baby girl. Let me feel it.”

I shattered. My orgasm crashed over me so hard my vision whited out, pussy pulsing around him in waves. He groaned, hips stuttering, and then he was coming too—hot, thick spurts flooding deep inside me, so much it leaked out around his shaft as he kept thrusting through it.

We stayed like that, panting, foreheads pressed together. His cum was already dripping down my thighs when he finally pulled out.

That was only the beginning.

After that night, we stopped pretending. Every evening became a slow burn - stolen kisses in the hallway, his hand slipping under my skirt while I tried to cook, me dropping to my knees in the living room to take him down my throat until he painted my tongue. He loved fucking me bare, loved watching his cock disappear into me and knowing there was nothing between us. I loved the way he’d growl “mine” against my neck when he came, filling me again and again.

Weeks blurred. My period was late by a week, then two. I bought a test on my way home from work one crisp November afternoon, heart hammering the whole drive. Dad was waiting in the living room when I got back, the little white stick already in my hand, unopened.

I looked at him, scared and exhilarated all at once. “I think… I think it might be positive.

”His eyes darkened with something fierce and protective. “Do it.

”I went to the bathroom. Three minutes later I stared at the two pink lines, hands shaking so badly I almost dropped the test. When I walked back out, he was right there in the doorway.

I held it up. “Dad… I’m pregnant.”

For a second he didn’t move. Then he pulled me into his arms so tightly I could barely breathe, kissing me like he’d never stop. His hand slid down to rest over my flat stomach.

“Our baby,” he whispered against my lips, voice rough with emotion. “You’re carrying my baby, Em.

”I nodded, tears spilling over. “I want this. I want you. All of it.”

He kissed me again, slower this time, full of promise. Then he scooped me up and carried me to his bed - our bed now - and laid me down like I was something precious. He undressed me carefully, reverently, pressing kisses over every inch of skin until he reached my belly and lingered there, whispering things I couldn’t quite hear but felt in my bones.

When he finally slid into me that night, it was different - deeper, more intense. He moved slow and steady, eyes locked on mine, one hand splayed protectively over the place where our child was already growing.

“I’m going to keep filling you like this,” he murmured, thrusting deep. “Every night. Until you’re round and glowing with my baby. Until everyone knows you’re mine.”

I came again, crying out his name, and he followed right after, pumping another load deep into my already-pregnant womb.

Nine months later, our daughter was born with his dark hair and my green eyes. We named her Hope.

And every night after that, when the house was quiet and the baby was sleeping, Dad would pull me close, hand resting on the soft curve of my belly where our next child was already growing, and remind me exactly who I belonged to.

Forever.
