All characters are over 18, fictional, and none of it ever happened. Think of it as a grimm fairytale.

A family planning man.
====================
I never felt such a large a cock or hand. He surprised me as I bent across the thick padded bedroom armchair, my eighteenth birthday gift he had given me that morning as I slowly woke. Over the back. Testing it for comfort. In my birthday satin nightie. He finally came to our room. Did he think I was tempting him? Perhaps.
His left hand went across my mouth and his weight settled on my back. I felt his hard cock for the first time. It was wonderful and full of promise and pressed into me. His right hand was around my waist and he pulled me back against his pelvis which he thrust forward. That night I learned for the first time, but not the last, how I love being trapped like that.
He lifted off for a moment to pull my nightie up and panties down. I kicked them off when he grunted at me. He spread my legs and I felt him pause, admiring his creation. Then he ran three deceptively gentle fingers of his right hand down my presented arse and between my legs. I knew if I struggled he wouldn't be gentle and I was tempted, but decided to be a "good girl" that first time.
He slid his first and third fingers along either side of my puffy pussy lips, and pushed his middle finger slowly through my slot, feeling everything, working back and forth. He was getting to know me. Getting to know what's his. He'd been waiting for today. Now he was exploring and taking what he'd waited for.
He took his time.
He pushed along my slot, wiggling through my inner lips and squeezing the outer lips. He felt my pee hole then backed up to press into my arse. Then forward again to work my clit. He was getting me ready. Wet. Engaged. Engorged. Warm. Tingly.
Then he pushed into my cunt and pressed gently at my hymen, feeling around for what seemed—and would become—a lifetime. After all it would soon be gone and he wanted to remember it.
"You're more beautiful than I dreamed," he finally said matter-of-factly, to himself, as if my body was none of my business.
I felt so chosen and so special.

Finally satisfied, his right hand returns and slides back to the front of my waist, under his satin gift to me, down to my downy gift to him.
Pressed against the armchair's coarseness I pretend to resist. I start to whine, "Nooo... Dad..."
Of course it has no effect, it's just further invitation and assurance. He knows me.
And he has his plan. I don't know it yet or how grand a plan it is, but we're going to learn soon, the two of us.
For now he slides his big palm down and cups and holds me like we've both dreamed of. His fingers work my bare skin, rough against smooth, strong to yielding, possessor to possession, intruder intruding, entering, claiming.
My blood carries his claim through my body, proclaiming, "We are being claimed. Owned. Put to purpose. Rejoice! Prepare! Awake! Partake!"
My arms, toes, breasts, cheeks, arse, nipples, sight, hearing and scenting nostrils all ignite. He has kindled a warm fire in me, soon to become a bonfire, and then a lifelong inferno.
He has the upper hand. He's dominant. I'm being overcome. I'm struggling for a breath, but still have enough to moan and groan.
Glowing colours and lightning flashes cross my emerald vision, which calls to my roaring blood, which breathes in his male musk, and that swells my breasts squeezed tight against my new padded chair, our breeding bench, one of his special gifts to us, and I am finally beneath his glorious weight.
My female reptile brain receives him as my pair-bond. My perfect lifelong mate has found me and I've found him. Sperm for my egg, semen for my womb, shaft for deep inside, his glans to nuzzle my uterus, his cock pulses to reward my orgasming cunt, my squeezing cunt to reward his pulsing shaft, my womb to receive his tribute from his balls, and give him his third child and first grandchild, first of many, and then great-grandchildren, and great-greats.
And she'll do the same when it's her turn.
Until now he was ever a gentleman. A caring and protective man. The best father and provider she and I could ever have. I know that will not change. We'll always be his loved and loving daughters.
But from today she and I are more than that. He never said. He didn't need. It was unspoken. In the family history, and his plans. We're in our place. He knows we're his. We're his birthright breeders, and he's opening us on our eighteenth birthday.
Now rough fingers—oh, his ever gloriously man-rough fingers—slick down into my slot and folds, to hidden holes, then slick back, to spread my eager waiting wetness around my swollen clit and lips.
Flashing lights and my roaring pulse drown out my last restraint. I'm keening now with no regard for anyone else in the household. As a token gesture he tightens his hand across my mouth, but he doesn't really care. They'll know soon enough.
I am a mare being put to service under a stud stallion. His strong left fingers are across my mouth like a service bridle, with two fingertips inside my cheeks as a steering bit. He's holding my mouth wide open. It's a grimace, a gaping wide-on, and my tongue is sticking out to its full extent through his fingers. He will tell us later it was like a slippery eel escaping, and we'll all laugh and cuddle.
As I moan, his right fingers—already deep inside my soft wetness—tense and stiffen, and he thrusts them in further. He is seeking what's his and whatever he finds he'll make his. His flesh, his pleasure, his reward, his cunt, his woman.
Oh my Lord, do not stop. Stiff finger, please find my small and untried entrance waiting just for you. Mine now yours. Thrusting in. Repeated. Preparing. Curling. Rummaging in my nest which waits impatiently yet patient. You will come in all good time. But quickly now, do not dally in your work. Yet please dilly-dally a while in me.
I feel pressure, pain and tearing. My maidenhead was my body's notional defence, existing only to yield to my sire. Now my sire is here. Sire, please violate me.
But my sire holds back. He won't tear my hymen with his finger. He'll use his cock. He has his plan.
I spread my legs wider, wanting his finger, even as I cry in muffled pain through his twisted fingers across and in my mouth. My tongue works wetly in and out between his fingers, tasting his salt. Is his semen salty?
