Notes: I do not own Marvel or any of the characters mentioned. Nebula is my favorite character in the Marvel Cinematic Universe, so I am a sick person to torture her like this.

Caution: Rape and Incest (Kind of? She IS adopted, so I don't know how that plays out) Do not read if you find the concept disturbing.

Pain. That was all Nebula had felt for the past 5 hours. She could see her limbs floating around her that had been separated but not fully removed from her body slowly being ripped apart by the energy holding her in place.

Having been in this position countless times before, Nebula had tactics not to be broken under the enemy's hand. She tried to focus on the minor irritations, such as her throat hurting from screaming or the deep ache in her lungs from lack of oxygen. Her cries of pain had stopped an hour ago, or had it been 2? It was so difficult to keep track of time.

She had been so foolish to think she could defeat Thanos. She wondered where she would be now if she had taken Gamora's offer to join the Guardians. Yes, all her sister's friends were idiotic, but they were happy together. They had a sense of loyalty to each other, not wanting to leave anyone behind. If she had accepted their offer and stayed with them, then pursued her father, would they have come for her? She doubted it. Her sister maybe. But who would be that stupid to risk their life for her, after everything she'd done in an attempt to murder them?

Suddenly the pain stopped. The energy that had been ripping her limbs halted, leaving Nebula gasping for breath. She was thankful for the break for a few seconds but then was plagued by the fear of the process starting all over again. She would enjoy these painless moments while they lasted.

Nebula was so distracted from her recovery she didn't even notice Thanos enter the chamber until he spoke.

"Nebula. Once you were my most loyal and fearless follower. Now a pitiful traitor who grovels at my feet. Did you really believe you could've killed me?"

Nebula looked up at her father. She wasn't going to let him have the pleasure of mocking her.

"Take off these bonds and let's find out."

Thanos chuckled. "Stubborn until the end." He stepped forward, his gaze examining her disassembled form.

"You are a traitor," Thanos continued. He looked at her closer as if attempting to peer through her soul. "But you are still my daughter."

"Wrong," Nebula snapped. "You are a deranged man who stole me from my home planet and murdered my people. You taught me how to kill the innocent and make them suffer. You are no father, to neither me nor my sisters and brothers."

Thanos didn't say anything, just lifted his gauntlet toward her. Nebula closed her eyes, expecting him to finish her off. To her surprise, she could feel her cybernetic parts adjusting. The pieces that had been removed from her body rearranged themselves to their original form. The power that had held her in place slowly distributed her in a kneeling position on the floor. Nebula took a moment to examine herself, ensuring her body had been repositioned correctly. Then she glared up at her "father."

Thanos sensed her rage. "Sweet Nebula. You know that actions have consequences. You needed to be taught a lesson."

"In what? To never harm my dear old father who ripped me apart, and permanently destroyed my body?" Nebula declared bitterly. Thanos didn't respond immediately, but Nebula saw him eying her up and down.

"You are quite pleasing to the eye," Thanos muttered softly as if he was talking to himself and not at all to her. "You are beautiful despite your altered body."

Nebula flinched. She had hardly ever been called beautiful in her lifespan. Most looked at her in disgust. They believed that she chose to be ripped apart and replaced with tech, like some freaks who wanted to live out their dreams of obtaining the "ultimate body." Others would stare at her out of the corner of their eyes: confused, trying to figure out if she was a cyborg or a full-fledged droid. Beautiful wasn't a word that appeared in these circumstances. The only time anyone complimented her appearance was when passing a bar where drunks and playboys would try to hitch a pleasure ride by flirting with her.

Thanos lifted his gauntlet, forming a glowing portal in the air. Nebula peered inside the portal, hoping it was a way out of this cursed ship. To her disappointment, it was a bedroom. She looked up at Thanos confused. He just nudged her toward the opening. "Go on."

Nebula walked through the doorway, unsure of why he would want her in this room of all places. It was a simple chamber, with a very large bed in the middle of the room and a dresser stuffed in a corner that most likely contained someone's attire. Was this Thanos's bedroom? Why would he take her here? She shifted uncomfortably, she would've felt more at ease if he lead her into another prison or torture chamber.

She turned around to face her father only to stop abruptly. Thanos's body was…smaller. He was still big compared to the average man. He must've used the Reality Stone to make himself this way. For what, she had no clue. She opened her mouth to comment but Thanos interrupted.

"I know you hate me, Nebula. But everything I've ever done was to make you stronger. Although Gamora was always my favorite, I always did care for you." Nebula looked at him and burst out laughing. No way was he actually serious. "Like hell you did!" She sneered through her chuckles.

Thanos ignored her reaction and stepped closer, studying her face. "Perhaps I should show you how much I love you."

He grabbed Nebula's arm and climbed up onto the bed, dragging Nebula along with him. His arms pinned her to the bed to make it difficult for her to move. He started to roughly tug her garments, trying to remove them from her small frame. Frightening images of what was about to commence flashed through her head. It made Nebula nauseous at the mere idea of her and her father practicing such unnatural acts. She knew he didn't need her permission for sex. She wasn't going to let that happen, not without a fight.

Thanos already had discarded her garments, leaving her in her bra and underwear. She took a deep breath. Using all her strength, she kicked him full force in the chest. Thanos stumbled back, falling off of the bed. This act of resistance only stunned him for a few seconds. Giving Nebula enough time to get off the bed and run towards the exit.

She didn't get far. She felt his large hand grab the back of her neck and drag her backward. Shoving her back on the bed, Nebula felt invisible bonds wrap around her wrists, pinning her to the mattress. Thanos towered over her and smirked.

"You're a smart girl. How far do you think that'll get you?"

"Obviously, enough to know when my father's an insane, perverted asshole!"

Thanos's hand reached over and brushed against her breasts, a little too close for comfort. Nebula twisted away from his touch.

Thanos sighed, irritated by her stubborn will. "I've already retrieved the information I need from you. What if I were to tell you that if you cooperate, I'll let you go."

If Nebula hadn't been in this vulnerable and humiliating position, she would've laughed.
"And what makes you think I'd believe you?"

Thanos gently placed her hand on her chin, lifting it to meet his eyes. "You know I don't lie, daughter."

Although Nebula would never admit it, the offer was tempting. Compliance in exchange for freedom. But how could she willingly let her father ruin her? After she'd left her father, she had promised herself that she would never obey his orders again. She would never break that promise.

"Surrender was never an option, you taught me that." Then Nebula bit down on his finger hard. Thanos pulled his hand away. He stared at the wound she had inflicted upon him, blood trickling down his fingers.

Thanos then ripped her bra and underwear off her body. The chilly air hit her and she shivered. But she had more important things to worry about other than the temperature.

Thanos used his large finger to slowly trace random shapes and patterns across Nebula's naked body. His large hands slid over her curves and breasts. He leaned over and kissed random parts of her body lovingly. In response, Nebula jerked up in hopes of headbutting him but missed.

"Hands off!"

"Hush, little one," Thanos murmured as if she were a child who needed to settle down.

Suddenly, Thanos swiftly pressed his lips to her own. Nebula let out a muffled shriek. She struggled to pull away and break away, but Thanos gripped the back of her head to steady her. His tongue found hers and explored the taste of her mouth hungrily. He kneaded and squeezed her bare breast eagerly, pressing himself against her, not caring if he crushed her petite body. Nebula was in desperate need of oxygen, the combination of his mouth covering hers and his large frame squeezing the air out of her lungs was making her feel dizzy. The instant she thought she would pass out Thanos pulled away, breaking the connection between their swollen lips. Nebula gasped out for air, dry heaving out of pure disgust.

"What the HELL was that!" Nebula screeched once she had caught her breath.

"Nebula," Thanos's tone was that of a disappointed parent scolding their child. "Perhaps I should tighten your restraints. But how I do like seeing you squirm under my touch…"

Thanos sat up and began removing his armor, never taking his eyes off Nebula. Once he'd removed a covering he tossed it aside, uncaring of where it landed. Then he started unbuckling his pants to which Nebula turned her head away. She felt a surge of power encircle her head, turning it back towards him.

Dangling between his legs was a huge purple cock. She couldn't help but stare, revolted at the disturbing sight. His member was huge and wrinkly, a lighter purple than the rest of his body. She wanted to throw up at the thought of that being forced inside her. It was much too big.

Then without warning, he stuffed one of his fingers into her hole. Nebula let out a loud long scream, not just in pain but also in surprise. His fingers were so huge, she was sure he was going to rip apart her pussy at any moment. But Thanos was careful, he must've had some experience for although her cunt hurt, it didn't tear. He removed his finger smoothly. He lifted his hand to mouth, his eyes never leaving hers, and licked the juices trickling down his hand. Nebula gagged. Thanos clicked his tongue in disapproval of her reaction.

"Stop being difficult, Nebula. All you're doing is making this harder on yourself."

"What kind of sick bastard gets off on his own daughter? Do you jerk off on the thoughts of touching Gamora too?"

Thanos ignored her comment. "Keep still, this is going to hurt more if you don't cooperate." Thanos grabbed both of her legs and with a swift tug and click, he forced her cybernetic legs into a different position. Spreading her legs wider for him. It hurt like hell, but Nebula held back a pained yelp. She needed to keep her spirit from crumbling apart, but even Thanos could tell she was losing the battle.

He positioned his cock right above her clit. Nebula could feel the warmth that radiated from it. Thanos slowly rubbed his member against her entrance, torturing Nebula with anticipation. Then he thrust his hips forward, cock filling every inch of her pussy. It hurt on every level of emotional pain. Yet, through the curtain of mental agony, was an intense pleasure.

Thanos rocked back and forth, sliding his member in and out. Nebula couldn't decide what was worse, her father's abusing her clit or the fact that a part of her enjoyed it. Her skull pounded, her head hurting at the sickening idea. She wanted the Guardians to show up and rescue her from this torment. She wanted to punch her father and run far away from here. But most of all she wanted to curl up in a ball and just cry.

Memories flooded her mind. She had only ever cried once. It had been the day her first limb had been removed. She was 15 and had returned after a failed mission awaiting her punishment. Even then, she waited until the operation was over, and she returned to her room so no one would see her cry. No, she would not give him the pleasure of seeing tears. But that did not stop her from screaming.

Thanos smiled as he saw his daughter struggling to block out the feelings of both pain and pleasure this experience forced on her.

"Enjoying ourselves, aren't we?" Thanos taunted, ramming his penis deeper into her hole, causing to Nebula arch her back painfully.

"Oh, F*** you!" Nebula screamed in anger.

"Language, child. If you don't learn to control your mouth, I'll gag you." Then he paused the abuse and looked thoughtful. "Or perhaps, your mouth can be used for a different purpose."

Nebula froze as her mind contemplated his words. "Oh, you just try. Afterward, you'd better hope that the reality stone can make a new cock, not that you have much of one anyway."

Thanos chuckled, "You have the true spirit of a warrior, almost as strong as Gamora. Let's see how long it'll take to break that spirit."

He squeezed her buttocks and groped her small breasts. He leaned forward, planting his lips on her neck, scattering love bites across her shoulders.

"You vile, disgusting monster!" Nebula shrieked ramming her torso against his chest trying to get away from him.

Despite her harsh insults, Nebula could tell she wasn't going to last much longer. Thanos was breaking her. She could feel tears brimming in her cybernetic eyes. It took every ounce of will to hold them back. She met the crazed man's lust-filled eyes. Perhaps if she let her guard down for just a moment. Let him see her true pain he would stop…

"Please Father," Nebula pleaded, her voice lowering to a small whimper. "Don't do this. I'll do better. I'll be better. I'll never fail or try to leave you again."

Thanos laughed, his voice rumbling and echoing throughout the chamber. "I thought we established before; you are a traitor. Therefore, you have no say in your future, little girl."

Nebula could feel herself coming close. Thanos was pleased to hear her moan softly. He grabbed her slim hips and pressed himself into her as deep as he could. Then they both hit orgasm. Nebula screamed as she came. Nebula's eyes rolled back into her head, and she closed them as the wave of pleasure rolled over her. Finally, a huge load of his sperm was ejected into her nonexistent womb. Thanos finally stopped pumping into her. He carefully pulled his massive cock out of her weeping pussy. He sat up and started wiping cum off both his and her thighs. She felt her invisible bonds loosen and disappear. To Nebula's outrage, Thanos wasn't even breathing that hard.

Nebula felt disgusting. It almost wasn't real. The cruel man who had raised her since infancy had raped her. Like an object to be discarded. Maybe because she already was nothing more than just that. An object to be used and tossed aside. That's when the tears came.

She felt big arms wrap around her gently and lift her. Nebula let herself go limp. She didn't even try to fight back. What was the point? Nebula felt tears drip off her cheeks as Thanos cradled her in his lap tenderly, like a child.

He whispered softly in her ear. "Shh. Daddy's here to protect you." If only those words were true.

Nebula trembled as she quietly sobbed. She didn't bother wiping away the tears trickling down her face. Tears of pain. Tears of anger. Tears of rejection. Tears of disgust. She was unloved by everyone. Who would have her now that her father had ruined her? She doubted Gamora could stand her if she learned of how Thanos had performed such a sick act on her.

After several minutes, her tears ceased. She looked up at her father to discover that he had returned to his original size. She glanced down to discover that both of their bodies were clothed. As if it had never happened.

Thanos carefully laid her down on the bed. He was gentle, acting like the caring father he claimed to be.

"There, there, child. It's all over now." Nebula couldn't believe how calm his voice was. Had he forgotten him molesting her just a few minutes ago?

His large finger pressed against her cheek softly. "You may stay here and rest. Don't go anywhere." His eyes flashed in warning. He leaned over and pressed his lips against her forehead gently. Then he stood up and left the room.

Nebula fell back on the mattress, staring up at the ceiling. She didn't even look at the door. If she even attempted escape, how many soldiers would be waiting to stop her outside? Nebula wiped a stray tear from her cheek. There was no point in crying again. After all, how would tears cleanse her damaged soul?
