TW: Incest, breeding kink, grooming?
You and Leona had always had a special bond. Some people would coo over how adorable it was - the second-born prince and his baby sister, always at each other's sides.
It was when Leona hit puberty that Farena had an issue with it. Leona was suddenly fighting Farena every step of the way and, as Leona pulled away, so did you.
He didn't know why.
He didn't know how Leona would be in your room begging: "Just the tip, please? It hurts so much, just help your big brother."
He didn't know that while he was running the country as you and Leona grew, Leona was ruining you.
Leona would be spending his rut buried within you, knotting you over and over again while silently hoping he would make you carry his pups.
During your heats, Leona either had you humping your little cunny onto his tongue or riding his large cock until your legs weren't able to carry any weight.
As the two of you grew, you only attached more to each other. When Leona was sixteen and was off to NRC, he insisted you go with him. Crowley had finally relented, allowing the two of you together to count as one student.
All that meant to Leona was that he had more time to fuck you senseless.
When Ruggie eventually turned up, Leona had a blast. Your heats would end up with your big brother knotting your cunt and his best friend in your ass.
"Get over here and let your big brother suck your tits, you know I sleep better when you let me."
His dorm room, empty classrooms, storage closets, and his personal favourite - the botanical garden - were all places he would drag you in order to fuck you dumb.
Your big brother's cock was the only cock you'd ever need. You were absolutely addicted to being stuffed full of his cum. His cocksleeve, his perfect little slutty cumdump. And if you were being especially good, then maybe he'd let his dormmates take turns filling you over and over again, turning you into a babbling mess of incoherent words.
There was hardly ever a moment you were empty.
"A-ah, n-nii-san! More, please, Leona-niiiii!"
"My good little slut, so drunk on your big brothers cock. You want me to knot you? Fill you with my pups so nobody can take you away or question who you belong to?"
You both already knew the answer. He'd trained you well, after all.
