“It’s to wake up, my love.”
Your eyes flutter open to see Duke Leto Atreides standing over your bed, one of his hands brushing back some of your hair away from your face. He smiles warmly when you tiredly meet his gaze, and holds out an open palm. You take it and let him help you sit up, though that’s as far as he’s willing to let you go. Leto hovers his hands over your baby bump, borderline paranoid about you doing anything that could jeopardize the health of the baby.
“I thought my appointment with the doctor wasn’t until next week, my lord…” You yawn, resting your hands on your belly as you fight off sleep. Being heavily pregnant was no easy task, and most days it feels like you have as much energy as a corpse.
“It is, I simply wanted to see you.” Leto answers, petting your hair and curling one arm around your lower back to support it. “When we’re alone, get rid of the ‘my lord’, what we have is more than the results of an obligation.”
You sigh, leaning into his touch as you consider his words. Months ago, you were just another member of the Duke’s harem. One of many meant to produce heirs until your body shriveled up. Your family was noteworthy but not noble enough to stay afloat, you heard that the Duke was looking for breeders and you left without looking back. Though you will admit that Leto Atreides is not the worst man you could’ve taken inside you. He was gentle and the way he kissed you suggested that he felt more than just gratitude.
You pretended to not mind the sounds and stories you heard from the other concubines in the beginning. You knew perfectly well what you were signing up for, the feelings came from nowhere, you swear.
Leto’s mannerisms during sex were impossibly adoring and intimate, and he would tell you were special every time in the midst of the afterglow. You stopped hearing heart dropping noises and nauseating stories, and the day after you found out you were pregnant you heard nothing at all. The Duke took longer than usual to meet with you that night.

“I’m sorry I kept you waiting.” Leto calls out, wrapping his arms around you from behind as you get ready for bed.
You finish tying the strings of your nightgown and turn around to face him. There are strange little flecks of red in the wrinkles on his face, but they could be a trick of the light so you brush the curiosity off.
“I am always waiting for you, my lord.” You repeat the same thing you say everyday, noting the way the corners of his smile flatten in displeasure.
He cups your face and walks the both of you backwards towards the bed, shooting his hands out to keep himself from crushing you when you inevitably fall on it.
Time passes by in a blur, every moment filled with cries of “Daddy” and overzealous movement from him that punches the breath of your lungs. He’s not incredibly rough, just passionate enough to have tears dot your lashes and his thumb buried in your mouth. Every kiss is a hot swirling mess of saliva and tongues colliding that gets you so wet, you really believe it could kill you.
“Mm, your tongue feels amazing, clumsily chasing after mine.” Leto grunts at some point, rutting and slamming his balls against your ass with no rhyme or reason. “The tightest cunt i’ve ever had, fuck-“
You hum around his thumb, suckling on it like he’s your god and his thick fingers in your mouth are your only reason to live. He grinds his teeth together when you make eye contact, and you struggle to keep it up as you hollow out your cheeks around his coarse digits.
“Wanna make you proud, Daddy, gonna be so good for you.” The words are muffled past the point of comprehension, but your eyes allow him to get the gist.
If you were not already pregnant, the flood of fresh cum in your pussy would’ve done the trick. You clench around your lord’s fat cock and let yourself break, squirting all over yourself.
When you come to, Leto’s busying himself with latching onto your tits like a leech and bullying your battered pussy.
“These are already so sensitive, aren’t they? And to think that I made them that way…” Leto trails off, licking a broad stripe over your nipple and pinching your clit.
You jolt and throw your head back, “Yes, Daddy, you did.”
He groans at the frequently used name, pinching your clit harder and digging his fingers in deeper. You’ve had more orgasms than you ever thought possible in the last hour alone, but your lord was insatiable like this. His head is too high in the clouds with visions of his future family to calm down.
Your legs shake but he takes his hand away from your clit and smooths his palm over your thigh to steady you.
“It’s alright, you know i won’t be too rough honey, you can take it. You’ve already taken my seed beautifully, growing my son in your womb.”
You know there’s no chance of stopping until Leto’s sure that he’s kissed and lavished every inch of your delectable body in Daddy’s attention. He gives each of your buds a ‘Goodbye for now’ kiss and wipes down the dips in your hips with his tongue, soothing the love bites and caressing the necklace of bruises around your neck he left when he lost control.

The bed sinks with Leto’s added weight, and your cheeks warm as you come back to the present. You look down at your joined hands to see a box clenched tightly in his free one. Like he’s scared of dropping it. You gaze up at him questioningly and he smiles once again before softly kissing the skin between your eyes.
Next thing you know, Duke Leto Atreides is kneeling before you and opening the box to reveal a large ring. It’s magnificently crafted and all the details align with your taste perfectly.
“Will you marry me?”
