You just came back from a mission to defeat a curse with Megumi and Yuji. You were exhausted and slightly hurt by the encounter, since you had some slight injuries. You walked into the building making your way to the weaponry not thinking much of it.
You couldn't stop thinking about what Nanami told you before you went on the mission. He showed a side of him you would never have expected from him. He told you with his usual stern voice "Be careful." Those words were replaying in your head and just the thought of it made your heart skip a beat.
You finally got the weaponry and you walked inside to clean your weapons. You closed the door behind you and once you looked inside, you saw Nanami toying and miticulously cleaning a gun. You felt your heartbeat go faster as a scenario pop into your mind. You brush it of as it was entirely sexual and cleared your throat to let it be known you were there.
Nanami looked up to see you in all your glory, your clothes hugging your body and despite the few cuts, he still thought to himself how hot you were. He felt his bulge growing in his pants and let out a grunt sitting up in the chair he was. He finally spoke up looking directly into your eyes. "You didn't listen to me" You were confused and taken aback by his words. You didn't really understand what he meant so you simply got more flustered and let out a gentle "W-what?"
He adjust his glasses before repeating his statement but added an explanation to it. "I told you to be careful, didn't I? Look at you. You were careless and now you are hurt." You felt yourself melt inside as your heart simply went faster in your chest. You didn't knew he cared so much, you didn't think it was that serious of a statement. You didn't know why but the right thing to do was to apologize. "I-I am sorry Nanami..." You broke eye contact as you couldnt bare to look at him longer. He let out a grunt and shook his head "An apology isn't enough, darling. You will have to, He paused and you heard him cuck his gun, prove to me that you are really sorry."
Your heart drop and your eyes went straight to the gun. Everything was so thrilling, it was straight out of a dream this couldn't really be happening could it. You gulped you felt yourself getting weaker barely able to stand but you tried to hide it. You finally spoke trying to play dumb even though you knew exactly what he wanted. "Killing me here would be really messy-" He let out a low growl as you stroke a nerve. "Dont play dumb with me, you are a slut for me. Dont you think I realized that, how you look at me hungrily, desperately? You crave me dont you? So get on your fucking knees"
You were at lost for words, all this time he knew. He saw through you like a open book. You let your pride go, he was right. The amount of time you masturbate yourself thinking it was him, moaning his name. You immediately dropped to your knees in front of him. You look up at him with desperate eyes. You looked at his bulge, god was it big and it just drove you more into this mindset of pure pleasure.
Nanami smirked letting out a small scoff "Good little whore, he pressed the gun to your temple, now get to work. Let's see if you can have the cum you crave so much and fantasize about." You nodded as the gun just made you feel more eager. You unbuckle his belt pulling his pants down before letting out a soft pant to the simple thought of sucking his cock. You pulled his pants down to show his treasure in all of his glory. It was big and exactly how you thought it would look like.
You finally took his cock in your mouth wrapping your lips on the tip gently bopping it as you twirl your tongue around it at the same occasion. You whimpered to the taste, it was exactly what you needed. After some few minutes you took more of his dick into your mouth, getting to the base of it, choking a little from having all of his cock in your mouth. Nanami grunted bucking his hips. You could feel his cock throbbing in your mouth, indicating that he was more than happy by what you were doing. You kept sucking, going up and down unto his cock. Your eyes watering from the gagging and the pleasure you felt. You were acting like a devoted cumslut for him and gosh he loved it. He spoke breathless and let out a giggle as well "Yes, darling, such a whore for me, argh yes haha..." He grunted and panted heavily "I am close darling, I am gonna cum in your mouth okay?"
You just went faster and harder as it triggered you. You needed that cum, that taste, desperately. Nanami grunted bucking his cock into your mouth letting a slight whimper as he ejaculated his thick load into your mouth. You felt your heart filled with joy and happiness as you swallowed the load without second thoughts. You pulled off to catch your breath some of his cum mixed with your drool running down your chin. You had that needy and devoted look stuck on your face. Nanami let out a chuckle before bringing the gun down on your chin to lift it up. "You belong to me now, is that clear darling?" You nodded looking lovingly into his eyes. He smirked and then put the gun down pulling his boxer as well as his pants before bringing you unto your lap. "Such a good little princess for me" He placed a hand on your cheek before kissing your lips softly. "You can rest on me if you want" He whispered out softly "I am so proud of you but next time..." He went to your ear smirking "Be careful"
