If there was one thing that Ronald Weasley despised, it was hand-me-downs.
His entire life, he'd been given his brother's cast-offs: his robes, his room, his books, his bloody familiar, even his wand for Merlin's sake!
It wouldn't have been so bad if all his siblings had been subjected to the same fate, but it seemed like there was always one reason or another for everyone else to have nicer, newer things than him. Bill and Charlie had been through school when Mum and Dad could still afford to buy them new or at least high quality secondhand. Percy was always getting presents for his high marks or making prefect or just being an all-around boot licker. And the twins, while Mum did buy them secondhand, ran through things faster than she could replace or repair them, so they at least got a rotating selection. Between their side hustles and their penchant for shoplifting (which Mum conveniently turned a blind eye to since it benefited her financially), they hadn't had to suffer nearly as much as Ron had throughout the years.
Growing up with Ginny was the one bright light in his childhood. She was the one thing he got to have that nobody else in his family did.
The twins might make her laugh with glee, but only Ron knew how to make her sigh with pleasure. Percy might be the one she went to for help with her studies, but it was Ron she came to in the middle of the night when nobody else was awake, her quiet moans muffled by a pillow or swallowed up by the pressure of his mouth on hers. Bill and Charlie might be the cool older brothers who knew just how to impress her, but Ron was the one who knew what every inch of Ginny tasted like and just where to touch her so that she came apart beneath him.
He wasn't sure exactly what the tipping point had been– the stack of girlie mags they found when snooping through the twins' room, accidentally walking in on Percy having a wank, or maybe even spying on Bill and his girlfriend as they fucked in the garden, thinking no one was around to see them 69 on the old stone bench they had out back. Either way, it had been like this for as long as Ron could remember: him and Ginny, exploring each other's bodies every chance they got.
The two years that Fred and George had gone off to Hogwarts without them were some of the best months of Ron's life. Mum was too distracted with housework and book club and whatever else a stay-at-home witch did to occupy her time. She was perfectly content to let Ron and Ginny amuse themselves all day, so long as they were down in time for breakfast and back in time for dinner with their father.
Most days, like today, they would play outside in the garden for an hour or two before sneaking back inside the house and up to Ron's room for some fun. Today, however, Ginny was itching to try something new.
"No, Gin, we shouldn't."
"Oh come on, big brother" she whined, pouting with those kissable pink lips that Ron had a weakness for. "It's like, one of the only things we haven't tried!"
"We're too young for that Gin," Ron blushed. "The other stuff is nice, but ten and nine is too young for…" He trailed off, too embarrassed to say it out loud.
Ginny had no such qualms.
"For fucking? Really, big brother, you'd think you wouldn't be so shy after all these years." Her bright brown eyes sparkled like honey in the sun, and he felt a swooping flutter in his stomach at the sight.
Merlin, she's so pretty. I'm so lucky to have her all to myself. Despite their copious amount of experience together, he was still nervous to do… that.
Pulling her thin tank top up and training bra up and over her head in one fluid motion, she crawled over to where he was sitting up against the headboard and straddled him, grinding herself on his lap and arching her back so that he had the perfect angle to pop one of her small, sensitive nipples into his mouth. Which he did happily, suckling on one of the rosy buds until it became a stiff peak before switching to the other with practiced ease.
She hummed with satisfaction, the sound shooting straight to Ron's cock, his erection fairly sizable for a boy his age. As he rutted against the thin fabric of her shorts, a part of him began to wish for more.
His mind was made up for him when Ginny shoved him lightly up against the headboard and claimed his mouth with her own, their tongues tangling for dominance before she pulled away and breathlessly asked, "Please, Ron. You're going away next year and I–" her voice broke, "I just want you to give me something to remember you by when I'm left all alone here."
Ron cupped her face in his hands and used his thumbs to gently wipe away the few stray tears that had fallen down her cheeks. Their next kiss was much more tender and chaste as Ron tried to pour all of the love and adoration he felt for his little sister into the gesture.
"Okay," he said softly when the kiss had ended.
"Okay? Okay!" All doubt melted away with the look of pure joy that she gave him at his words. Suddenly nervous, she bit her bottom lip and said, "I guess we should both get naked then, right?"
He gulped, nodding his head in silent agreement. She took a deep breath and reached for the hem of his shirt, helping him get it off. Soon enough, they were both laid bare to the other, nothing in between them but heat, trust, and desire.
Over the years, he'd probably touched and seen her naked body millions of times, from when they were toddlers washing each other's naughty parts to when he'd first walk in on her touching herself and she'd invited him to join in, but there was something special about the way she looked today, waiting patiently in his bed like a princess waiting for her prince.
Maybe it was her slightly parted, slightly swollen lips as she looked up at him with something that took his breath away. Or the constellations of freckles spanning nearly every part of her, ones he'd mapped over and over again with his mouth and hands. Or the knowledge that the glistening sheen across her exposed slit was all because she wanted him inside her. Him. Nobody else.
Sliding his cock completely inside his sister's unbelievably tight hole for the first time was an exquisite experience that would be burned into his mind forever especially on those long, lonely nights where he would be forced to stroke himself in the privacy of his four-poster bed at Hogwarts, hundreds of kilometers away from the girl who owned his heart. As he came deep inside her, coating her too-young womb with his seed, Ron vowed that she would never have anyone else.
She was his, and Ronald Billius Weasley was done with having to settle for leftovers.
