God, I'd love to slam my cock into my daughter as soon as she turns 18. Counting down the minutes, second by second, until I can finally feel my little girl clench down her extremely barely legal cunny around my cock.
"Shh, kiddo, Daddy's just taking what he needs. You can take it, baby. This is what I raised you for, after all." I'd grunt into my little fuckdoll's ears as the flames of her birthday candles flicker.
Large, veiny hands wrapped around her soft, teenage body — groping and pinching, mauling at her tight, youthful body. In and out, I'd drive my thick, grown up cock inside her tiny, pink fuckhole, stretching it out. Under me, she'd bury her face in her pillow, pushing her ass up to meet her dad's violent thrusts. Just a brainless little kid sexdoll for Daddy.
"Fuck, princess, you're so, so sloppy. Your cunny's such a filthy, wet mess right now. You love how hard Daddy's taking your fresh, tight cunt, don't you? Do you want to cum over Daddy's cock, baby? Do you want to be my silly little cocksleeve daughter?"
She'd groan incoherently into the pillow, cunt spasming around my grown cock. God, it'd feel so fucking good claiming my daughter as my personal cum dumpster. Dad's kiddo fuckhole.
But that wouldn't be it. I'd slide myself out of her leaky, drooling hole and crawl up to her limp head. I'd grab a fistful of her hair and raise her head up so she's eye level with my pulsing dick. I'd make her use her hands at first.
Tiny hands on such a big, thick cock. Such a gross, icky, obscene look. Her nails done up especially for her birthday slowly moving up and down my shaft as I look down at her face, twisted with lust.
"Go ahead, baby... use your lips. Kiss your siblings first," I'd say as her lips meet my balls. I'd groan, not from the sensation but from how utterly fucked up it'd be to make my own barely legal sextoy daughter make out with my balls.
"Such a good girl. I knew I raised you right, baby. And now that you're 18, we're going to have so much more fun, aren't we?" I'd tell her as her warm mouth meets the tip of my cock. She looks up at me, wide eyes, cheeks hollow as she sucks my dick and jerks it off slowly with her frail little hands.
"Shit, I can't wait to teach you all Daddy's nasty kinks and fantasies. I can't wait to groom all my vilest thoughts into you, baby. I'm going to teach my daughter how to drain her dad's balls so fucking hard. My own kiddo fuckslut, FUCK."
I'd groan one last time, hot jets of cum blasted down the back of my teenage daughter's throat less than an hour after her 18th birthday. I'd pull out slightly, watching my final streaks of icky cum spray her face. Marking her.
Making my daughter mine forever.
