Work Text:
August was practically bouncing with excitement as his older sister finally pulled into the driveway. Since she had started college he only really got to see her on holidays or a few times during summer break, so he was naturally excited to get to see her for so long. On top of that their parents had left for some long business retreat, so it was just going to be the two of them.
August ran up and hugged his sister as soon as she got out of her car, and just her scent alone had all his great memories of her flooding back. Lucie hugged her brother back just as eagerly, and they both let go after a few blissful moments.
“Wow, you’ve really changed since Christmas. I wouldn’t even think you were the same boy!”
August’s heart fluttered with euphoria when his sister called him a boy. He did in fact look a bit different. Mainly, he had cut his red hair into a bit of a ruffled pixie cut, with bangs still over his forehead. Aside from that and a bit of a wardrobe shift to a punk/goth vibe, he was essentially the same. Green eyes, freckles, pinkish skin, and a general femininity that made him look at best androgynous.
“Yeah!! I’m way happier with my hair now, plus it’s way easier to take care of.”
“You’re lucky you like it short so much, I still have to take care of this mess.”
Lucie gestured towards her curly brown hair, which went slightly past her shoulders. She had taken a lot more after their father, having brown eyes and dark skin. She was also of course a good bit taller than her younger brother. Lucie varied more in what she wore, though right now had on a red beanie and a varsity jacket.
August laughed as his sister ruffled his hair some more, and he quickly helped her get her things inside.
=====
It was probably ten PM by the time August was getting tired. He had been spending time with Lucie all day, and was actually up quite a bit later than normal. Though once his sister could tell he needed some rest she eventually accompanied him to his room. Lucie fished around in her brother’s closet for some pajamas, though most of what was in there was still pretty girly.
“Yeah, don’t bother with those. I prefer just sleeping in whatever I’m already wearing.”
“That must suck, man.” August’s heart lit up at that, even with how common and usually meaningless it was to call someone that. It still didn’t take away from the looming dysphoria though. August turned away from his older sister and curled up a little. Lucie sat down on his bed and rubbed his shoulder gently. “I know a pretty good way to help with dysphoria, y’know.”
August perked up slightly. “You do?”
“Yeah, you wanna see?”
“Mhm.” Lucie got up and switched the lights off, while also subtly locking the door out of instinct. She began undressing then, causing her younger brother to blush. “It’s okay dude, we’re family and all that. You gotta get naked too though.”
August nodded slowly, a bit confused, but still trusting his big sister. He began delicately pulling his clothes off and setting them aside, until he got to his panties. His chest was too flat to need a bra, although he still tried to cover it with his arms. Lucie smirked, being down to her underwear as well. “C’mon lil bro, men don’t gotta hide their chests.”
August’s face lit up more, and he blushed with euphoria this time as he uncovered his budding breasts.
“That’s it~” Lucie said, slipping into bed with the young boy. “You look so manly like that- Aside from these.“
Lucie was up against August’s back now, pulling on the hem of his panties.
“S-Should I take them off…?” He asked.
“Of course, what kinda man wears panties?”
With this confirmation August quickly pulled them off and tossed them to the side, breathing shakily now that he was fully exposed.
“Oh you look so handsome like this~”
“I-I do~?” August asked, his voice dripping with elation.
“Of course you do~ Now…” Lucie wrapped her arms around August’s chest and pulled him into her body. Her hands began gently exploring his small form, running over his chest stomach. He gasped and shook slightly at these sensitive touches, and he squirmed especially when she began rubbing both his breasts.
“I-I don’t think that I like this…”
“C’mon, little bro. Don’t you trust me~?”
“O-Of course I trust you.”
Lucie smirked and suddenly moved her hand over his pussy, pressing her middle finger into his slit. August immediately let out a scrawny moan, before his mouth was covered by Lucie’s hand.
“You have to be quiet, okay? Can you be a good boy and be quiet for me~?”
August quickly nodded and Lucie moved her hand away. He breathed shakily for a moment, but didn’t make any more noise.
“Oh that’s such a good boy~~”
August’s voice cracked a little from the horribly intense feeling between his legs. Lucie slowly began moving her hand up and down his slit and he let a breathy moan out uncontrollably. Lucie continued to rub his pussy and her little brother squirmed uncomfortably while struggling not to make any noise. That was all he was focusing on, as he didn’t want to think about how much he hated what she was doing. The way she was making him feel by touching him down there made him want to vomit, but he couldn’t think about that right now or else he might actually do it. Or worse, stop loving his big sister.
After a few moments of strained silence from August, Lucie decided to reward him again.
“Oh you’re such a good boy for me~ You’re such a strong, handsome boy~ You’re making your big sister so proud~”
August whined and Lucie could feel him getting wet. She quickened her pace and really felt him squirm, even feeling his breathing and his heartbeat while she had her hand on his exposed chest. Lucie kept whispering gender affirming nothings into the boy’s ear as she kept caressing his young, nubile body. She kept telling him how good of a boy he was and how happy he was making his big sister, his idol. Lucie knew he thought of her that way because for a long time now she had been keeping track of exactly how he acted around her and what he said about her, as well as which things she said that got her little brother all flushed and euphoric. She had been keeping track of it all in her mind, and that work was finally paying off exactly as she had hoped.
Lucie’s whispers only served to cloud August’s mind in a hazy fog, the euphoric phrases somehow mixing with his disgust while also exemplifying the undeniable pleasure she was forcing him to feel. August didn’t feel like he hated it anymore, but he *wanted* to hate it. Every fiber of his being was telling him what was happening was entirely abhorrent and disgusting, but every one of his big sister’s little touches and every one of her little words of encouragement only made him want to keep going. He wanted her to stop so badly, but he knew that if she did he would only ache for her to continue. He even knew that when this did eventually end he wouldn’t- he couldn’t see her any differently, aside from being even more attached to her. Lucie was showing him something no one had ever shown him in his life, so that had to mean that he was extremely special to her. He was the only person she would share this with. August took solace in that thought now, playing it over and over in his head.
It hurt now, but all this would do is make him love his big sister more.
Lucie pressed her finger deeper between August’s folds, causing him to let out a small squeak of pleasure.
“Shh, shh~ Be a good boy for Lucie, baby~”
A shiver ran up August’s body when he was called that. Something felt supremely wrong about that petname, but at the same time it made him feel even more elated. He nodded through the harsh sensations, willing himself to do just as his big sister had asked. Lucie whispered another ‘good boy’ in his ear, and, finally willing to go all the way, she carefully slid her finger deep inside him.
August had to shut this mouth as hard as he could to stop himself from moaning as loud as possible, and on top of that he had to grip the bed sheets so hard that it made his knuckles turn white. He suddenly felt his body convulse, and it took the tensing of most of his muscles to again stop him from letting out a screech of pleasure.
Lucie felt the pulsing of August’s pussy and the excess fluid dripping onto her fingers, and she quickly pulled out of him. What was no doubt his first orgasm was entirely caused by her, and the painfully hard member between her legs was desperate to be free of her panties. Her rationality was still intact though, as well as her love for her younger brother, so she knew that step would have to wait. Instead she wiped her hand off and wrapped her arms tightly around August, holding him close and bombarding him with love.
“You’re the best boy in the world~ No other man could make me as proud as you just did~ You’re special to me in a way absolutely no one else is~”
August naturally hung on his older sister’s every word, feeling his still rapidly beating heart swell with joy. He gently put one hand on Lucie’s and tried to close his legs as best he could to stop the uncomfortable pulsing and leaking. This did little, but it wasn’t long before both of them were asleep together anyway.
