Yuji opened his eyes and found himself in, possibly, the weirdest situation he had ever been in. And that was saying a lot. Sitting up as much as he could, he blinked, looking around at the small cabin he was in. Considering last time he checked, he was at school, in his dorm room, he wasn’t quite sure how he got here. Or how he had ended up in the condition he was in. Which was naked, but tied up in red ribbons that were shockingly strong enough to keep him from breaking out. After a moment, he focused completely on the ribbon, trying to break free anyway he could.
He was so focused on the ribbons that kept him immobile that he didn’t hear the footsteps coming towards him until he heard a very familiar chuckle. Looking up, he wasn’t shocked to see Sukuna standing there, looking overly amused.
“Sukuna! What’s going on!” Yuji demanded as he struggled, trying to get untied.
“Why, Yuji~ Don’t you know it’s Christmastime?” Sukuna asked, clapping his hands, causing lights to suddenly turn on above him.
Yuji blinked when he looked up and realized he wasn’t just laying on the floor, but he was actually laying under a huge tree, covered in colored lights and balls. Putting two and two together, Yuji flushed.
“Wait, am I…?” Yuji squeaked.
“My present? Oh yes. I thought it was appropriate.” Sukuna grinned as he knelt down.
Yuji yelped as he was dragged out from under the tree and placed on Sukuna’s lap. He squirmed a bit, flushing as Sukuna ran his hands over Yuji’s chest and tied arms.
“I was right, the red looks so pretty on you. Of course, I would like it better if it was rope, but this is fine too.” Sukuna purred.
“What are you…?” Yuji trailed off, biting his lip.
“Why, I’m enjoying my Christmas present, Yuji. I’m sure I will get plenty of use out of it.” Sukuna snickered.
“Ah~” Yuji moaned lightly as Sukuna ran his hands over Yuji’s nipples, making them harden into peaks.
Sukuna nipped at his throat, grinning as Yuji’s body started to relax into his own. His little host was learning, leaning towards his touch with each sigh of pleasure and delight. He was beginning to understand that only Sukuna could give him the pleasure he craved. Yuji squirmed again and whimpered, his dick twitching to life as Sukuna touched and rubbed every inch of available skin.
“Look at you. All wrapped up nice and tight. Unable to do anything as I touch you as much as I want.” Sukuna whispered in his ear.
Yuji shivered a bit, but didn’t move away. If anything, he pressed closer.
“I’m going to untie you bit by bit, taking my time with each inch. When I’m done, you are going to beg me to fuck you. Hard and fast.” Sukuna said as he started with Yuji’s legs.
He cut the piece holding his legs together, pulling them apart so he could run his hands over Yuji’s thighs and calves, squeezing and running his nails over the sensitive skin. He even snickered at the sight of a little gold bow on the very tip of Yuji’s dick, matching the one on Yuji’s head.
“Feels good.” Yuji slurred a little.
Drunk on the warmth of Sukuna’s body and the soft touching, Yuji closed his eyes and sighed. His breathing hitched when his hands drifted closer and closer to Yuji’s dick, but moved right past it, going over his hips instead.
“You didn’t think it was that easy, did you?” Sukuna snickered.
Sukuna ground his dick against Yuji’s ass and nipped harsly at his shoulder.
“You are my present. You exist for my pleasure. You will come when I decide you will.” Sukuna hissed and Yuji squeezed his hands together.
“P-Please?” Yuji whimpered.
Sukuna perked up a bit, curious.
“Please what?” Sukuna ran his nails over Yuji’s abs and Yuji whined.
Yuji turned his head and kissed Sukuna’s cheek, much to his surprise. Yuji’s eyes were watery and his face was flushed.
“C-Can I have a kiss?” Yuji muttered.
Sukuna hummed, pretending to think about it, just to make Yuji’s face fall, looking quite heartbroken before Sukuna’s hand came up and he cupped the back of his head, pressing their lips together harshly. Yuji moaned, pressing closer, opening his mouth when Sukuna requested it. In response, Sukuna’s other hand moved down and lightly rubbed Yuji’s tip. Yuji whined loudly and Sukuna pulled back, delighted at the glazed over look in his eyes.
“Look at you. Look how happy you are, completely at my mercy. I could play with you until you are completely mindless. I could keep you like this for hours. Watching you fall apart until you can’t even think straight anymore. Unable to think about anything except my cock.” Sukuna stated sweetly.
Yuji’s eyes widened and he looked a little scared, but Sukuna just kissed his cheek.
“But that’s an idea for later. Right now, I’m going to tell you what I want. I want to open you up and use your cute, little ass as my own personal cumdumpster.” Sukuna nuzzled his neck and Yuji whimpered.
“Sukuna~” Yuji whined as Sukuna settled his teeth against Yuji’s neck and pressed hard enough to make an indentation.
Yuji jerked when he felt a finger slip into him. He didn’t even realize when Sukuna had pulled some lube out from under the tree and covered his finger. He sighed, feeling the finger move around, hoping the curse would take some mercy on him and touch that one place inside him, but he doubted it.
“You know, Yuji, I know exactly what you are thinking. How much you want me to touch that little piece inside you, but not to worry. I’m going to take good care of my little gift.” Sukuna stated.
Yuji yelped as he was thrown to the floor, his ass jerked up and his head forced down. He tried to move, but just like that, Sukuna shoved two fingers into him and pressed against that button that made stars explode in his eyes. Sukuna was rough, almost brutal compared to how gentle he had been before, but Yuji couldn’t have cared less. It felt so good, his whole body was on fire and he couldn’t control his mouth as he babbled and begged Sukuna to fuck him.
“P-Please! Please, Sukuna, please I want it so bad!” Yuji cried.
Sukuna snickered and pulled his fingers out before laying across Yuji’s back, his cock pressed against Yuji’s eager hole. Yuji tried to move back, tried to get Sukuna inside him, but Sukuna held him still.
“Yuji, tell me you want me. Tell me you want me to fill you up so good.” Sukuna cooed.
Yuji panted heavily, eyes wet, as he turned his head. Sukuna could only think about how adorable his host looked, completely at his mercy and mindless with pleasure. How he wanted to see this vision forever.
“Please! I want it so bad. I want you to fill me up!” Yuji moaned.
Sukuna pressed in just enough for the tip to pop past Yuji’s inner ring, but stopped again. Yuji sobbed, unable to understand why Sukuna was teasing him so much.
“Tell me how much you want my cum inside you. Tell me you want to be mine.” Sukuna growled.
Sukuna was panting too and Yuji felt a small bit of pride that he was able to get the King of Curses so riled up. Sukuna always seemed so untouchable and yet, Yuji had seen him lose control with just sex alone. Sure, he wasn’t in control, but it was nice to know he affected Sukuna just as much as Sukuna affected him.
“I want to be your’s! Please fill me up!” Yuji begged.
Sukuna pressed in a bit more and Yuji let out a wail. He felt like he would die if Sukuna didn’t fill him up soon. Sukuna pressed down on his back, nuzzled against his shoulder and their eyes were locked.
“My host. Only mine.” Sukuna muttered and then slammed in the rest of the way.
Yuji howled as Sukuna moved in him roughly. There was no pauses, no breaks, Sukuna pounded into him like he wanted Yuji to always remember the feel of his cock in his ass. Yuji clawed at the floor, trying not to lose his mind as Sukuna bit and scratched his shoulders and back. He could feel the skin tearing, but it almost added to it.
“Mine, mine, mine!” Sukuna growled.
Yuji whined as he felt blood roll down his back and sides. It hurt, but it also felt good and Yuji was falling into a dark, blissful place. Sukuna suddenly groaned, stopping completely and Yuji whined when he felt warm cum splash inside him. Sukuna paused, laying on top of him as Yuji squirmed.
“Sukuna. Please.” Yuji moaned.
“Not yet.” Sukuna muttered.
Yuji felt Sukuna twitch back to life inside him and gasped, unable to stop his eyes from rolling back in his head. He felt like his dick was about to explode, like every nerve in his body was standing on end. Sukuna pulled back and started to move inside him again, nice and slow, grinding against that special place and making sure to cause Yuji to feel like he was starting to go mad. He wanted it, he wanted it so badly. He hiccuped before he let out a sob.
“S-Sukuna.” Yuji muttered, voice hoarse.
Sukuna chuckled and his hand settled in Yuji’s hair, petting the sweat soaked strands. Yuji pressed against it, sighing, soaking up the affection.
“So good for me. Taking me so well. How happy you are with me inside you. Tell me, my dear host, if you could keep me inside you at all times, would you? Would you be happy, stuffed full of me every minute of every day?” Sukuna cooed.
Yuji nodded enthusiastically, his brain absolutely mush, but his imagination ran wild with the idea and he groaned as his cock gave a painful twitch. The idea of going to school, training, even going out on missions with Sukuna’s cock constantly inside him was extremely hot, Sukuna purred in delight, seeing the way his usually confident and defiant host fell to absolute pieces in his arms, under his ministrations.
“Yuji~ Tell me, pet, can you be a good boy for me and only come when I tell you to? Can I take that mean bow off your cock and have you stop yourself from exploding? I wonder.” Sukuna snickered.
Yuji was positive he couldn’t do it, was absolutely sure he would come the second Sukuna took the bow off, but there was something thrilling about the idea.
“I-I can’t!” Yuji whimpered.
Sukuna shrugged and grabbed the ribbon.
“I suggest you do as you are told or this is going to be painful, for you anyway.” Sukuna warned.
Yuji squeezed his eyes shut as Sukuna removed the bow and slammed against him. It was like trying to hold back a bomb, but somehow Yuji managed to. Sukuna hummed, quite impressed.
“Good boy. Look how well you follow orders.” Sukuna sneered as he grabbed Yuji’s hair and jerked his head up.
Yuji yelped, eyes wide as he leaned over, cock grinding against his pleasure button.
“Now, come.” Sukuna hissed.
Yuji blacked out when his body let go. When he woke up, he was curled against Sukuna’s chest, wrapped in a blanket and the ribbons were gone, leaving him free to move. He blinked sluggishly and just cuddled against Sukuna’s chest quietly, eyes closing as Sukuna played with his hair.
“Good boy.”
