A/N: I've been really obsessed with Red Keeper lately but the problem is, there's no Red Keeper/Reader fanfiction so I took matters into my own hands. If you recognize it from Ranger Reject, I don't own it.

You rushed over to an empty guest room, catching a brief glimpse of yourself all dolled up in the mirror as you plopped yourself on your bed, crying into the pillow as the day's events played in your mind. It had just been one party, you were at the Ranger Headquarters wearing the red dress Red Keeper liked. You stood by his side, smiling to collect one of the many sponsors at the event. Getting ignored by these very men while they talked to Red Keeper. Acknowledged by them only as an object, mocked and belittled with Red Keeper encouraging them. Insulting your intelligence, your abilities, your own worth and, when you tried to get a word in, immediately dismissed. You had run off, bearing more than you could take. Locking yourself in one of the empty guest rooms for solace trying to convince yourself you were safe until a brutal knock reminded you that you were anything but.

"(Y/N)!" Red Keeper yelled from the other side. "Unlock this door!"

You buried your face further into your pillow, wanting to silence the voice that had caused you misery.

"Now, (Y/N)!" he yelled again as he violently knocked.

You covered your head with your pillow hoping that if you ignored it, if you ignored him, he'd give up and go back to the party. Surround himself with admirers who stroked his massive ego. Unfortunately, he wasn't one to be deterred.

"(Y/N), if you don't unlock this door, I'm breaking it down!" he yelled at you.

You finally lifted your head from the pillow, angrily turning towards the door as your heart pounded. If it were anyone else, you would've just continued ignoring them but you knew that Red Keeper was more than capable of breaking the door down. You got up from your bed, not even bothering to fix yourself up as you opened the door.

"What do you want?" you demanded as you saw him on the other side.

Red Keeper froze, looking at the tears in your eyes as they fell down your cheeks.

"(Y/N)?" he asked. "You look like a mess."

Great, the first words out of his mouth and it was the most insulting thing he could think of.

"If I am, it's because of you," you told him.

"Now now, (Y/N), don't be like that," Red Keeper said cupping your cheeks in his gloved hands.

He wiped away your tears, his lips formed into a frown as his cold leathery gloved hand stroked your cheek. Your body shook, torn between whether to put your hand on his or to toss it aside.

"Was this about the party?" Red Keeper asked in his sweetest voice. "It was just a joke. I never met to hurt you."

You looked into the red visor blocking his eyes. A part of you wondering if they were mocking you. Beaming with a sick pride about the bimbo he had wrapped around his finger.

"You did," you said as you backed away.

You wanted him to know you were hurt. That you hated being treated like you were no different from his divine sword, an object he carried around and showed off to the public for attention.

"You could've talked to me about it," Red Keeper said walking towards you. "Instead you left me all on my own." Red Keeper stepped inside, shutting the door behind him. "Leaving me to face the fakes and suck-ups without my beautiful girlfriend by my side." He gave you a sadistic smile as you found yourself backed up against the wall. "Making me the laughing stock of the people who keep the Ranger Battalion afloat."

You were about to run, dash for the door but Red Keeper wrapped his hand around your neck, lifting you up against the very wall that kept you from escaping. Your heart pounding as his sadistic smile grew wider.

"I wonder, (Y/N), how should I punish you?" he teased. "I could just beat you but then I'd ruin that pretty face." Red Keeper's grip tightened, making your head feel light. "Choke the life out of you?" Red Keeper's grip loosened. "No, what good would the lesson be if you're not alive to learn it?"

You told your body to fight, to struggle against him with every ounce of strength you possessed but it was frozen stiff as your mind started to scream. The sorrow and anger replaced by fear as Red Keeper kept you in his grip. The psychopath threw you on the bed without so much as a warning, pinning you down and taking your lips roughly before you could escape. You froze but your heart started to pound in a new way as you wrapped your arms around his waist, pulling him closer and deepening the kiss as passion took over. Red Keeper's tongue entered your mouth, exploring every inch as his hand ran up your leg. The touch of his hand reminded you of your anger from before and causing you to push him away.

"Stop!" you told him.

Red Keeper ignored you, moving his mouth to your neck and sucking on it sharply enough to leave a mark reminding everyone that you were his and only his. Despite your anger with him, you couldn't help the moans that escaped your lips, moans that grew louder as you felt his hand going underneath your panties, his finger slowing spinning your clit into tight circles. Red Keeper took his lips away from your neck, looking down on you underneath that sexy red visor.

"I'm sorry, (Y/N)," he said as his finger started to speed up. "Did you want me to stop?"

Red Keeper's finger moved to your entrance, ghosting your pussy lips. He gave an innocent smile while he traced your opening, feeling how wet he had made you. Your mind was screaming, "Run! Get this mad man off!" Yet your body ached for him.

"No," you said desperately gazing up into his visor. "Please."

"Please what?" Red Keeper asked innocently.

"Please... continue," you begged.

He put his gloved fingers in your wet pussy, causing your hips to rock as he thrusted them inside of you, his thumb stroking your clit as your moans grew louder.

"You like this?" he asked. "You like when I finger fuck you? Use your body as a toy?"

"Y-Yes!" you managed to say through your moans as you rocked your hips on his gloved fingers.

"You get pissed at me, tell me you want me to go away," Red Keeper mocked as his fingers explored inside of you. "But you need what I do to you. You love how I make you feel."

You stayed silent, closing your eyes as you focused on the caress of his thumb rubbing your clit while his fingers scissored inside of you. Consumed by your need for this man. This man who had threatened you and was now bringing you to new heights of pleasure. Red Keeper's fingers stopped, looking down on you like you were at his mercy, which you pretty much were.

"But are my fingers enough?" Red Keeper asked. "Or do you need more?"

"More," you admitted. "Please, I need more!"

"More of what?" Red Keeper taunted. "More of my fingers?" Your eyes traveled southward to the clear bulge in his pants. "Or do you want my cock?"

"Your cock!" you begged. "Please, I need that divine cock!"

Red Keeper turned you around, making you face the mirror and seeing the mess he had made of you. He gave a satisfied smile and pressed a button on his belt, turning his one piece suit into a two piece, and then freed his long hard cock.

"See what you do to me?" he asked, his hands gripping your head. "How hard you make me?

"Yes," you said, your eyes gazing hungrily at the cock in the mirror.

"You want this?" he taunted.

"Yes," you pleaded, your entrance begging for him to fill you. "I need your divine tool!"

"Then say you're sorry," he ordered. "Say to me, 'I'm sorry for humiliating you in front of everyone.'"

Your anger from earlier came back. You had humiliated him? He had humiliated you! Red Keeper yanked your hair, causing you to scream in both pain and pleasure. Your mind forgetting your anger once again and consumed with the need for his cock.

"I'm sorry I humiliated you!" you pleaded. "I'll never leave again! Please!"

Red Keeper gave a triumphant grin as he grabbed your hips, roughly shoving his cock into you. You let out a loud cry as your body rocked back and forth along his long and hard member.

"Now say the name of the man who brings you to your knees!" he ordered. "The man who makes you scream!"

"SOUSEI!" you screamed.

Red Keeper gave your ass a hard smack as he thrusted inside of you, causing you to yelp.

"RED KEEPER!" you screamed. "ONLY RED KEEPER!"

"Yes!" he cried out. "Now tell me who you belong to!"

"YOU!" you screamed. "ONLY YOU!"

Red Keeper pulled down the top of your dress, exposing your breasts as he pile drived into you. You watched yourself in the mirror as you saw your tits bouncing back and forth, your eyes rolling over to the back of your head and your mouth making the most wonderful screams as Red Keeper used you. Bringing you closer and closer to release.

"RED KEEPER!" you screamed. "I'M TRANSFORMING!"

"Yes, let it out!" he said, stroking your clit with his gloved finger.

You transformed all over his divine tool, rocking your hips as you released all over his cock. Red Keeper kept hold of you, thrusting a few more times until he fully released inside of you. You watched yourself in the mirror, panting as Red Keeper's grip loosened, collapsing on your bed. Red Keeper pulled out of you, falling to his knees and laid on top of you, stroking your hair as he smiled.

"You're mine," he reminded you.

"Yes," you said, your mind still in a daze. "All yours and only yours."

Your mind knew that none of this was right. That he was an evil and sadistic man. A psychopath who pretended to care about protecting the human race when, in reality, the only thing he cared about was protecting his own reputation. Yet your body needed him. How was it possible that someone so bad could make you feel so good? Make you crave and dread his touch? Red Keeper drew you out of your thoughts, stroking your hand as he laid soft kisses along your neck.

"Think you can behave yourself now?" Red Keeper asked.

Yes, the party. The one where you were supposed to suck up to the richest people in Japan for a desperate attempt at sponsors. Earlier you would've said no. You would've told him exactly where he could shove it and thrown him out. Now your head was so clouded in euphoria that all you could manage was a nod. A nod that promised to be his obedient pet as you came to a painful truth. That Red Keeper was your drug and, like an addict, you would do anything to get your next fix.

A/N: So, how was that for my first reader-insert lemon? Just know that I am not glorifying abusive relationships but, as this is Red Keeper, he's not someone you can have a healthy relationship with. I wanted to write something sadistic that could fit with his character, so I went with a terrible relationship that you can't leave because the sex is so addictive. As for the belt thing, I made that up just so you could have sex with him in his Dragon Keeper suit. Anyway, leave a comment letting me know what you think. I also have a Ranger Reject RP Book that you can check out if you're interested in role-playing in that world. I know I'd love to have you.
