This Life Is On My Side

Summary:

Camilla and Leo give in to deep desires, ones that shouldn't be given in to.

Work Text:

Camilla couldn’t remember much of her early childhood. The earliest memory she had was seeing all her siblings together, in front of their father, King Garon. No mother to be seen. As they grew older, their father became more disdainful of the world around him. Some days, he wouldn’t even leave the throne room to tend to his children. She later picked up that none of them were bound by blood. Rather, all of them, except for Xander, were born from concubines. Women who yearned for Garon’s heart after the death of Queen Katerina.

With no motherly figure in their lives, she felt it was best to be that figure for her siblings, even Xander, the eldest of the four. If their father couldn’t bother to even spare a glance at them, she would give them the attention they needed, no, the attention they deserved. She would always remind them that they had each other, that nothing could break a family.

As they continued to grow up, Xander eventually grew out of the need for care and guidance. He was focused on his duties as crown prince of Nohr. He no longer had time to be with his siblings. And when he did, it was always short. Camilla was rather quick to adapt to this sudden change of pace between her and her elder brother. He had grown to hold himself high. He was more than capable of caring for himself. Perhaps her job was done with him.

Elise, being the youngest, still got the right amount of attention from Camilla, maybe a little bit more than enough. They would play games, share a meal, and explore the castle every single day. She never tired of her younger sister’s energy. But she knew that, one day, Elise would grow past the need for her. So, she’d make the most of their time together.

And then there was Leo.

When Leo was going through adolescence, he found himself focusing less on his magical studies, for there was something far more important to spend his time on. Constantly caring for him day after day, Camilla was taking up more of his mind. It was wrong, and he knew that at his age. Her well-developed body, even back then, caught his attention more than the magic he had been so enthusiastic about a short time ago.

Eventually, he discovered the act of self-pleasure.

From that point forward, night after night, Leo would masturbate before he would fall asleep. And every single time, it would be about Camilla. He would imagine her naked body. Her luscious curves. It was routine for him. By day, he was the same studious, intelligent Leo his siblings had known him as. But by night, he was jerking himself off thinking about his older sister.

Until one night, after reaching his climax, he was filled with regret. Every night, his seed was spilled in the name of his sibling. It wasn’t right. When the two would spend time together, he struggled between looking at her deep purple irises and the cleavage she proudly put on display with her clothing. It wasn’t right. When they walked through the massive hallways of the castle, he would fall back ever slightly, just to get a look at her ass, swaying with each step she took. He swore she did it on purpose, accentuating the curves for the attention. Still, it wasn’t right for him to be the one giving it to her.

That’s when he swore to himself, he would no longer spend his nights dwelling on Camilla. For his safety, for her, for the rest of his siblings, he would try to forget about these feelings. There was a subtle change in Leo’s attitude from that point forward. Every time Camilla tried to spend some time with her dear brother, he would turn away. “I must continue with my studies,” he’d say. His days were now spent in his room, or in the castle’s vast library, only ever seeing his siblings for supper. Every other time, he was alone.

It went like that for years. Camilla had grown used to Leo’s distance. As much as it pained her to see her younger brother pulling himself away from her and the others in the name of perfecting his craft, she had a respect for his dedication and chose to leave him be. Besides, she still had Elise and Corrin. Leo was at the same age when Xander started to distance himself, she believed it was inevitable for him to do the same.

But that wasn’t true. It couldn’t be farther from the truth. In fact, the more Leo stayed away, the more he yearned to go back to the old days.

He missed being able to spend so much time with Camilla. But he felt it was too late to ask for her care already. How embarrassing would it be for him to ask that at his age? Those feelings for her returned, and they were stronger than ever before. Eventually, he relapsed on those nights of self-pleasure. He began to masturbate again, still thinking of his elder sister and her further-developed body. Those plump lips, her large breasts, her curvy backside and full thighs. It felt disgusting, yet so good at the same time to be dwelling on the image.

And on one faithful night, as he came close to reaching his climax, Camilla made the abnormal decision to check on her little brother before heading to bed herself.

She saw him, his loungewear off, cock at full mast, his hand gently wrapping around it. His body became tense seeing a familiar set of purple hair peeking through his doorway. “S-Sister,” he said in a panic. “I-It’s not what it looks like!” He needed to stop, but how could he when the one and only subject of fantasy was standing in front of him? His hand slowly continued to stroke at his member.

It was disgusting. Pervasive. Camilla should have been disgusted. She should have left, closed the door, and spent the night attempting to forget what she saw. But she didn’t.

In fact, in some twisted way, it intrigued her. So much so that she found herself walking ever closer to Leo. Her mouth was slightly open as she stared at her brother’s cock. “Tell me, dear brother…” her voice caused his cock to throb in his hand. “Would you like some help?”

Deep in the night, unbeknownst to anyone residing in Castle Krakenburg, two of the Nohrian royal siblings were together.

And they were doing something that siblings shouldn’t have been doing together.

Leo was sat on Camilla’s lap, her soft and plump lips were showering his cheek and neck with kisses as she was slowly, methodically, stroking his cock. It didn’t take long for her to know the pace and speed that pleasured her dear brother best. Hearing his moans and whimpers, the occasional, “Sister…” as she pleasured him was like music to her ears. She only ever wanted to take care of her siblings.

As he let out a moan, failing to dampen its volume with his hand, his hips bucked as a few strands of semen shot out from his tip, staining Camilla’s hand. She was quick to snag one last drop with her index and bring it up to her mouth. Leo could only watch as she licked her hand clean of his fluids, teasing him with one final view of it resting on her tongue before she swallowed it all. She said nothing, only giggled with a coy smile on her face.

“Do you feel better, dear?” she asked him.

That day forward, whenever Leo felt the need to release, all he needed to do was call on Camilla to help. It was a win for them both. Camilla was able to take care of her brother again, and Leo was able to indulge in his sister jerking him off.

“Let your big sister take care of you,” she would always say in a sultry voice before taking the reins.

For a while, all she would do was use her hand. It got the job done, it satisfied her brother and his urges. But one day she was feeling racy. “Let me know when you’re getting close, dear brother,” she requested.

The moment he yelped out that he was close to climaxing, she quickly repositioned himself, shoving his entire length into her mouth, throating it all. She would suck him off for only a few seconds before he’d buck his hips again, and she’d taste his seed straight from the tap. She moaned with each spurt of semen that pumped out of his tip and down her gullet.

From that point, she’d begin to use her mouth regularly to pleasure Leo.

As each day passed, her methods became more and more risqué. She had gone from using her hand to her mouth, to eventually teasing him with other parts of her body. She would slide his cock between her heavy breasts, squishing them together and almost suffocating his rod with pleasure. She’d grind on him, teasing him with both of her orifices, getting so close where a simply push of a finger would guide him into her deepest regions, but letting it slide so gently past them.

They knew all too well that this was wrong. But to them, it felt so right.

On some days, Leo would be the one going to Camilla’s bedroom in the evening, practically begging for her help. He would suck on her nipples like a baby as she gently teased his cock, looking at him with a loving and caring gaze. The same one she wore when they were younger. Only this time, it meant something completely new.

Soon after, Leo began to pleasure Camilla. “I want you to pleasure me too, Leo,” she requested. He was happy to oblige. Anything for his big sister. He’d use his hands and mouth to satisfy Camilla’s own urges. They no longer pleasured themselves, they were only pleasuring each other.

It was only inevitable for them to take the next big step.

They had enough with the teasing. Now they were making love. Camilla was unable to suppress her moans as Leo would thrust slowly, yet deeply inside of her. He’d bury his face in her chest to stifle his own grunts and moans of pleasure. He had perfected the skill of pulling out before climaxing rather quickly. When he felt himself getting closer to that point, he’d quickly slide himself out of Camilla, stroking his cock at a rapid pace before releasing several strands of semen all over his sister’s body.

The lovemaking eventually became something more primal. They were no longer making love. They were fucking. And they were fucking hard. Whether it was Leo on top, bending his sister over her own bed and tugging at her purple hair to see the faces she’d make. Or if it was Camilla on top, riding him until her hips were sore. Though Leo always preferred that she took control.

They had become animals. Their moans were no longer being suppressed. It was as if they wanted the maids and butlers of the castle, their siblings, even their own father, to hear two siblings of the Nohrian royal family giving into their carnal instincts on one another.

As ferocity increased, so too did their need for pleasure. Now, their time together was no longer exclusive to the late evenings. In the mornings, Camilla would help Leo with the erection he found himself with as soon as he woke up. In the afternoons, Leo would bury his tongue deep into Camilla’s pussy. Before supper, they were kissing one another, everywhere, no crevice went untouched by lips. But late evenings were still their only opportunity to indulge.

“I want to feel you deep inside me, dear brother,” she said one night, spreading her holes open, allowing Leo to see her anus, winking in need. He didn’t hesitate to stick his cock in, opening it up, beginning to morph the hole to his cock. She was gripping the bedsheets as he thrusted himself deeper and deeper inside of her.

Anal became another part of the routine.

And at the end of each night, after spending close to an hour, sometimes more, of teasing, loving, fucking, they found themselves holding one another. Their naked bodies intertwined as they cuddled. Even if their energy was spent, more time was spent vigorously kissing, letting their tongues tango.

“I love you, Camilla.” Leo would say at the end of each night.

Camilla would gently hum, pressing one final kiss on his forehead. “I love you too, Leo," she would reply right after.
