Prompt: Gavincest non-con/dub-con dirty talk. Kristoph holds Klavier down and talks dirty to him until he comes. Klavier completely gets off on whatever Kristoph is saying, even though he doesn't want to. It's okay if Klavier starts trying to rub himself off on Kristoph or whatever table/wall/bed he's pinned against toward the end, but Kristoph himself shouldn't touch him more than is necessary to hold him in place.
Any time period is fine, but no crack please.

I attempted. c:

"Hey, little brother. Want to play a game?"

Kristoph smirked, but somehow managed to look as controlled as he ever did. He was arched backwards, not even touching his brother other than his palms that shoved into Klavier's forearms to hold him against his bedroom wall. Klavier himself was already breathing heavily in apprehension, interpreting the look on Kristoph's face as something other than what it really was. He wriggled his arms a little, because if he didn't fidget or move somehow he was going to go nuts. Kristoph leaned his head in towards Klavier's face, never touching him, hot breath just barely tickling his exposed ear.

"Klavier...I think we need to spend a bit more quality time together...to bond as brothers..."

Klavier didn't respond. He was transfixed on his older brother's voice, both hearing and feeling his inhaling and exhaling as he spoke--all the hills and valleys of his elegant way of speaking. Kristoph tightened his grip to make sure his little brother did not move, and continued.

"I'm not sure you realize what effect you have on me...You're a forbidden fruit, mein bruder..."

More hot breath in his ear. Klavier lidded his eyes and sighed heavily, legs twitching absently as his pants tightened. He loved his brother's accent--always more prominant than his. It was so...sultry, so seductive. His face heated up, and he struggled to keep a sharp concentration on his brother's words.

"Klavier...I want to take you, you know that? Don't you understand what I want to do to you? Every time I see you, schatzi. It's...overwhelming. I want to give you everything you've ever wanted. I want to make you scream. To scream, and never be able to forget it...You need to see me...to feel me every time you close your eyes..."

Why...Why was Kristoph so far away? Klavier needed him closer. His thrashed his hips forward, but they met with nothing but air. He whined loudly, wordlessly pleading for friction but not getting his desire fufilled. It was torture... He needed someone...something! Anything! But the closest thing was his brother...and he was too far out of reach. Klavier let out a throaty moan in both arousal and frustration--begging.

"...Getting anxious, Klavier?"

Kristoph let out a harsh chuckle, but it didn't feel harsh. It felt warm, and teasing. Klavier may have been looking too much into it, but he couldn't restrain himself. He fought against his brother's palms, trying to reach downward with his hands. However, Kristoph's grip was undying and forceful.

"Tch. Klavier, don't you remember?"

Kristoph moved his head down smoothly, his movements surreal. He was whispering into the base of Klavier's neck--still just far enough away that his brother could feel nothing but his breath.

Klavier...Can you really not control yourself? This is just a...conversation...That's all..."

The masked chiding tone of his older brother did nothing to help his situation. His erection poked clearly between his leatherbound legs, Kristoph acting as though he didn't even notice it. Didn't even notice his brother's burning desire. Klavier's fingers ached to help himself, but his older brother stopped him. If Kristoph didn't stop this soon, he was going to--

"However, what I said before still stands, bruder. The effect you have on me is...powerful. Dangerous. Strong..."

Klavier couldn't take it anymore. As much as he yearned for friction against him, as much as he wished he could just force his brother closer to him, feeling his tongue and his teeth move against his skin as he talked...

"B...Brother--Aah!" Klavier had been working to keep his mouth shut during the entire ordeal. He had to hold back as much as he could. But he couldn't. Not anymore. His face flushed red in lust and mortification as he felt himself slip off the edge, and he came without ever being touched, his climax hitting him hard. He bit his lip, trying to hold himself back, but it was far too late. He felt himself sink, and his breathing was slowly turning more regular as his color returned. Kristoph only tutted and shook his head, dropping his little brother, who slid down the wall slowly and tensed his arms to try and work feeling back into them.

"Such a shame, Klavier. I had hoped you weren't that weak..."
