Jealous Flames (Jealous Kyojuro Rengoku x F!Reader)

Rengoku watched you from a distance, he watched you smile and laugh with the Water Hashira….Giyu Tomioka. As he watched you from a distance, he couldn’t help but feel a little tingle in his heart. Were you cheating on him with Giyu? Was he not good enough for you?! As he clenched his fist, knuckles turning white he started to walk to your direction. While you didn’t pay attention to your boyfriend who was making his way towards you guys. You were far too busy laughing like a school girl with Giyu.

“Oh really? That’s very interesting Giyu!” You said giggling slightly. Giyu was your childhood friend, you’ve been friends with him forever now. Yes he was very quite but you didn’t mind at all. “So how are you and Shin-” You began to say but you were cut off by someone’s hand on your shoulder.

“Hello guys! Am I interpreting something..” 

Jumping slightly as you heard a loud booming voice, you turn around and see your boyfriend. “Hello Darling, oh not at all. Giyu and I were just talking.” You say sweetly, Rengoku just stared at you. Your smile at the moment made him frown, but he soon then forced a smile. “Then you wouldn’t mind if we talked.” 

You shook your head and turn to Giyu. “I’ll see you later Giyu.” You say smiling, as Rengoku grabbed your hand and before your friend could reply to you your jealous boyfriend pulled you away from him. Walking away from him, as you walk with him you smile at him. “Is there anything you need Sweetheart?” Rengoku didn’t answer, he was silent which made you frown. “Hey are you okay?” 

He didn’t answer you, he just continued to walk. After awhile you made it to his room he opened the door for you so you could walk in and he followed behind you. Closing the door behind him, he then looked at you. 

“You’ve been spending time with Water Boy.” He said harshly, looking at you. You could see the flames in his eyes. Wait was he jealous?

“Water boy? Who’s water boy?” You began to say, as you were confused but it hit you he was talking about Giyu. “Are you speaking of Giyu?” You shake your head and sigh. “Kyojuro, he’s only a friend.”

Rengoku scoffed and rolled his eyes at you, he crossed his arms over his chest. “Yeah right. Then why are you spending so much time with him? You’ve been spending more time with him rather than me Your Boyfriend!” He began to say, and raising his voice at you. “Are you cheating on me! Was I not good enough for you!” He began saying, as he took a step closer to you and looking down at you. 

“Are you being serious right now! Of course I’m not cheating on you, Like I said he’s only a friend!” You say, and taking a step back. And he just took a step closer to you. 

“Yeah right, I bet you’re a cheating little whore.” He said, smirking down at you. Rengoku was upset and angry at you. His comment made you frown, he’s never talked to you like that before. 

“Are you serious, I’m not cheating on you! Get it through your thick skull!” You say, and rolled your eyes. Soon after tears started to stream down your face. You push him away from you and walk past him. “You’re unbelievable!” 

As you wanted to walk passed him he grabbed you and pinned you against the wall. He placed his forehead against the wall, and he was breathing heavily. “Don’t you dare walk away from me.” He snarled close to your ear. “God..you little whore. Why I gotta punish you.” And with that he placed his lips against your neck. Quickly finding your sweet spot. His hands finding their way to your hips, grabbing them roughly. “You’re mine..” He growled out lowly. 

You just stood there shocked. You’ve never seen your boyfriend act like this. He was usually happy and cheerful towards you, and he was always so gentle towards you. “Rengoku..What are you doi-.” You began to say but were cut off with his lips smashing against yours. You wanted to push him away from you but this new attitude of his is making your knees weak and your underwear damp with your wetness. 

He didn’t pay attention to you, he quickly deepen the kiss. Licking the bottom of your lip asking for permission and to which you gladly granted. His tongue slipped inside your mouth, exploring on what is his. Both of your tongues fighting to dominate each other. And of course he won, he was making your knees weak to which you had to wrap your arms around his neck brining him closer against your body. 

He pulled away and both of you were breathing heavily. He looked at you and one of his hands grabbed your face quite roughly. “Hm I think you should be punished. Hm?” He said, and that hand slowly left your face and made it’s way to your neck. Wrapping his hand around your neck and applying a little bit of pressure. “You’re gonna stand there and do as I say, understood?” 

You quickly nodded, making him smirk. He released his grip from your neck. Leaning in again he began to kiss your neck, he began to suck on your sensitive skin. “You’re mine…You don’t belong to water boy..” He said harshly against your skin. Making you whimper in enjoyment. As he was marking your neck you felt something poke your stomach, and he pulled away. “Ah look at that, you’ve got me hard.” He said, grabbing a fist full of your hair. “Now what are you going to do to help me out huh?” 

He pulled on your hair slightly, as he smirked at you. “Mmm Rengoku..” You moaned out. “I can help you you, you just have to let go of me.” 

He couldn’t help but smirk at you and your reaction. He let go of your hair and took a step back. You got on your knees and slowly started to undo his belt and bottoms. You threw the belt to the side and pulled down his pants down along with his boxers. His cock sprung up, precum dripping from it already. 

“Well hurry up before I shove it down your throat.” He said, grabbing your hair once again and began to guild your mouth to his hard cock. You placed a small kiss on the tip of his cock, earning a deep groan from him. And slowly you began to lick his shaft. Starting from his balls and making your way up, at this point you were teasing him. And he just gripped onto your hair more harshly. 

Getting the hint you stopped and slowly you wrapped your lips around his head, licking the sweet salty precum. And you slowly started to take his length into your mouth, you fully didn’t take in his whole length in since you didn’t wanna gag. You began to bob your head to his length and he just stood there biting his lip, throwing his head back. Hearing his deep moans made you wet, so with your other hand you shoved it down your bottoms rubbing your clit moaning around his hardness. 

“Who in the hell gave you permission to touch yourself!” He said, pulling your hair hard. Making you whimper against him. Quickly you removed your hand away from your bottoms and whimper. “I was planning on being nice to you but you asked for this,” He said, his hand making it’s way to the back of your head and forcing his full length in your mouth causing you to gag, but he just held you in place. “Suck it Princess. I bet you’re already used to sucking off Water Boy huh?”

As you take time to fully get used to his length in your mouth you slowly began to move your head. He let out a loud groan, throwing his head back. Closing his eyes as he enjoyed the moment. You tried your best not to gag around him, tears streaming down your eyes. “Hmphm” You moaned out. Rengoku eyes snapped back to you, and you both were looking at each other, staring at each other’s eyes. As you sucked him off, you grabbed his balls with a free hand and began to rub them gently. 

“Oh you keep that up you’re gonna make me cum Princess.” He moaned, and as you picked up your pace and rub his balls even more he began to thrust into your mouth. And after awhile he moaned out loudly and started to spill out his warm cum down your throat. “Don’t you dare spit it out, swallow everything.” He said harshly, you whimper and pulled away. Swallowing every drop of his jizz. 

Before you could react he pulled you up and pinned you against the wall. He began to rip your clothes off. And he removed his top off, now both of you were fully naked in front of each other. He placed a kiss on your lips and shoving his tongue into your mouth tasting himself. His fingers made their way down to your inner thighs, you got the hint and opened your legs for him. He began to rub your clit slowly. “God you’re so wet, and for what? Just by sucking me off? God you little whore.” 

You moaned into the kiss as he rubbed your clit, and he pulled away and looked you in the eye and without warning he shoved two fingers inside of you. “So fucking wet for me..is that right?” He said, as he moved his fingers in and out of your cunt. Making you moan out. “Yes, god I’m so wet for you.” 

Making him smirk, he looked at you. “Now that I think about it. Little dirty whore don’t deserve to moan.” He pulled his fingers out of your needy hole and he bent down and picked up his belt. “Now hold still.” He said, and he wrapped the belt around your mouth. “That’s better! Now where were we? Ah right~!” He said, and shoved his two fingers inside of you and slowly he moved him. In and out, a quick and rough pace. Making you moan, your moans were muffed by the belt.

And Rengoku just smirked, he watched you so intensely. As he moved his two fingers inside of you he knew your special and sweet spots so he did the best to hit them and while his thumb was rubbing your needy clit making you hitch your breath. “I bet water boy also fingers you like this right? But not as good as me right Princess?” 

Making you throw you head back and whimper against the damn belt. Rengoku just chuckled at your reaction. As he picked up his pace you started to shiver, your legs began to shake and he took notice in this. “Such a weak little whore huh? Very well then wrap your legs around my waist I’ll hold you.” 

And you did what he told you, wrapping your legs around his waist and he held you up and against the wall. 

He felt your walls began to clench around his finger and he quickly pulled them out. “You don’t deserve to cum…not yet.” Making you whimper and roll your eyes. God if only this damn belt wasn’t around your mouth. As his fingers were covered in your wet juices he couldn’t help but suck on his own fingers moaning to himself. “So fucking delicious…mm you’re tasty.”

“Now are you ready to take my lovely cock huh?” He said, looking at you deep in your eyes. You just nodded and he smiled sweety at you and placed a gentle kiss on your lips. He align his needy hard cock to your hole and slowly he pushed himself inside you, feeling your walls clench around him. Making him groan loudly. “God you’re so tight.” 

Your muffed moans sounded so good to him. As he was fully inside of you he gave you the time adjust to his size. After awhile he began to move his hips in and out. His hips rocking against you. As he held you tight, you wrap your legs more against his hips. Moving your hips with his pace. 

Rengoku started to move roughly against your hips. Hitting your sweet spots, he knew you so well. He knew how to make your knees weak for him. “God you’re a good little slut huh?” He asked you, looking into your eyes. And he saw your eyes, tears streaming down your face and your muffed moans. You just nodded and moaned against the belt. He smirked and took off the belt around your mouth and threw it across the room. Pressing his lips against yours, sucking on your bottom lip making you moan out for him. 

“Oh god Rengoku~” You moaned against his lips. Deeping the heated kiss you guys have going on. 

He pulled away, biting your lower lip. “You take me cock so well? Do you also take water boy’s cock well too?” He said, his hips moving more rough with you. Hitting your g-spot making you gasp out.

“No, I’m only yours…I’m your whore.” You moan out, as he began to hit your g-spot. “Fuck, you’re m-making me f-feel so good honey.” You say out, gasping. Leaning and you placing your head on his shoulder. Making him chuckle, he began to move faster than ever. His balls slapping against your skin.

“I’m close princess…I want you to cum with me.” He said. “I want you to rub your clit for me, can you do that?’ He cooed against your ear. 

You reacted to quickly and your hand making it’s way your clit and you began to rub your bundle of joy with two fingers. Both of you were moaning eachorther’s names. 

“Fuck I’m close Rengoku!” You moan out.

“Me too! Fuck…now!” He moaned out, spilling inside of you. Your walls tighten against him and soon after you came around his cock. He just stood there holding you, both of you panting heavily. Catching your breath, the orgasm taking so much from you. You went limp, and Rengoku noticed this and carried you over to his bed. He then pulled out, moaning softly. He watched your wet hole filled with his cum. 

As you laid on the bed, he sat besides you. The room was filled with pure silence until he spoke softly. “I’m sorry I don’t know what came over me Y/N.” He said, laying besides you. 

You look at him and sigh and lay your head on his chest. “No it’s okay..I just don’t know why you’re so jealous over Giyu.” 

“It’s because, you spend so much time with him. And I guess I just felt left out..” He said, looking down and away from you. Making you frown and sigh. You have been spending more time with him so you can see why he got jealous.

“I’m sorry Sweetheart, I didn’t mean to hurt your feelings. But I assure you he’s only a friend. The reason why I’ve been spending more time with him is because he needed help finding the courage to ask out Shinobu.” You say, and immediately Rengoku turned red and was mentally screaming. 

“Oh my! I’m so sorry Y/N! I didn’t know!” He began to ramble feeling embarrassed now. You giggle and place a kiss on his lips to shut him up. He was surprised and returned the kiss, after awhile you pulled away.

“And besides why would I pick Water Boy if I already you.” You say, teasing him about the name he was calling your friend. And Rengoku bluhsed even more. 

“Please don’t remind me of that!” He said whimpering softly making you giggle. You playfully roll your eyes. “Oh okay you handsome flame.” 

“Hey Y/N…I love you.” He said. 

“I love you too Sweetheart.” You say back.
