Yuuji's hands were bound above his head, a thigh bar connected to a rope in the ceiling forcing him to keep his legs spread open and up in the air. He's already blissed out, panting and sweating from his first two easy orgasms as Sukuna eased him into their long night. He was taught the color system and he trusted Sukuna, but this wasn't something he'd ever done before so he was a bit nervous.
So far, all Sukuna had done was spank him a bit, edge him obnoxiously with his fingers–which he secretly enjoyed, surprisingly–, and degrade him. They hadn't used any props or toys yet, and Yuuji was starting to get comfortable. He quickly realized that was a big mistake.
"Ever heard of a Hitachi wand?" Sukuna asked, reaching behind Yuuji to plug something in. When he came back into view, Yuuji saw a really large wand type toy with a bulbous head on it and felt his flush deepen.
"N-no sir." He responded immediately.
"Well today's your lucky day." Sukuna turned the large, powerful vibrator on low and looked up at Yuuji with a devilish smirk. "What's your color, baby?"
Yuuji's eyes widened as his pussy clenched, instantly leaking slick as he swallowed hard. "G-Green, sir."
"Good boy." Sukuna purred, dragging his fingers lightly over Yuuji's slicked up cunt. "New rule since you like to be such a needy little whore. If you want to cum, you have to get permission first. If you cum without permission, you'll be punished."
Yuuji's breath caught in his throat, his cock twitching not only at the concept but at the fact that Sukuna's dominant tone left zero room for argument.
"One more time. I won't ask again for a while. You'll just have to say it if need be. Color?" Sukuna eyed him dangerously. A shiver ran down Yuuji's spine as sweat dripped into his eyes. He nodded his head eagerly, biting back a groan at the thought of what was to come.
"Green, sir."
The glint in Sukuna's eyes matched the predatory smile on his lips. "Things are about to get a little more difficult, Yuuji. You're gonna feel a bit overwhelmed, but you're strong. I know you can handle it. If you're comfortable with what I just said and want to keep going, I promise you endless orgasms."
Endless orgasms? Yuuji couldn't stop the soft moan that left his swollen lips. He nodded his head fervently. "Please, sir."
Sukuna looked Yuuji over slowly, as if devouring him with his eyes while he ran his left palm slowly over Yuuji's defined abdomen, tracing light fingertips down the deep crease if Yuuji's V. "Daddy's gonna make you see stars, love." He whispered quietly, his voice gruff as he dragged the vibrating wand across Yuuji's folds, making sure to miss his swollen cock on purpose with every teasing stroke. Yuuji whimpered quietly, laying his head back and closing his eyes. "What is it baby? Such a needy little whore that you can't even wait just a few minutes for daddy to make you scream?" He chuckled darkly, eyeing Yuuji's fluttering cunt. "Still so wet and needy. What? Two times wasn't enough? So fucking selfish."
Yuuji whined quietly, forcing himself not to buck his hips. The last time he did that, Daddy denied his orgasm and left him sobbing. "I'm sorry, sir." Sukuna swatted his ass, earning Yuuji a painful sting that had his breath catching and teeth clenching. "D-daddy! I-I'm sorry, Daddy!" He quickly corrected himself.
"You learn so fast, baby. So proud of you." Sukuna whispered, watching every twitch Yuuji's body made as his left hand traced feather light touches along Yuuji's thigh. The praise went straight to Yuuji's cunt. His chest filled with pride, and a small smile crossed his lips. He made his daddy proud. Most of their play tonight had been degrading. He hadn't received much praise. That should have been a warning, but Yuuji was too naive to know any better.
As soon as the words left Sukuna's lips the now slick, vibrating bulb of the wand was pressed firmly against Yuuji's already sensitive clit and electricity shot through the boy's core. His legs instantly tried to close, but the bar between them kept them torturously open as his toes curled.
"Ooh— fuck !!" It was all Yuuji could manage as Sukuna immediately turned the vibrations up, punching the air out of Yuuji's lungs and sending him spiraling quickly to his next orgasm. Luckily he still had enough sense to him to remember he was supposed to ask for permission before cumming. He wasn't sure if he would be able to stop it if Sukuna said no at this point, though. "D-Daddy! Please—I'm gonna–oh my god–I need to—please!!!" He cried out, his legs lifting his hips off the mattress as he tried his best to hold himself back from the edge.
"Not yet baby. Come on, hold it for daddy." Sukuna cooed as he gently rubbed the wand over Yuuj's throbbing clit, watching the boy beneath him writh beautifully.
"Daddy—I can't! Please–nghh!–Please let me cum! Please!" Tears brimmed pitifully in Yuuji's eyes now, his skin on fire as his stomach coiled tighter than it ever has. It started off as a lot but it quickly became too much .
"Do you need to cum baby? You wanna cum for daddy??" Sukuna asked, the usual calm and in control tone of his voice wavering slightly as excitement gets the better of him. Yuuji was just too beautiful like this. Sukuna's cock throbbed painfully in his jeans but he wanted to focus on Yuuji. He would focus on that later. Right now, he wanted to tear his boy apart first.
"Please! Fuck—Daddy please! Let me cum! I can't take it!" Yuuji made eye contact with Sukuna and regretted it immediately. The look in Sukuna's eyes pushed him to his breaking point. If Sukuna said no this time, he was getting punished for sure.
"Cum." Sukuna commanded and it was like a switch was flipped in Yuuji's brain. He let go completely as his vision whited out, a high pitched, nearly feminine sounding whine left his lips as pure, white hot pleasure crashed over him, making his legs shake violently in their restraints as his eyes crossed.
Sukuna watched in amazement as Yuuji's body bowed entirely off of the bed by the strength in his legs alone and he had to swallow hard and take a deep breath so he didn't cum on the spot. When Yuuji finally came down from his high and started squirming and crying out from the overstimulation, Sukuna removed the wand from his cock and allowed him to catch his breath.
"What do you say baby?" Sukuna asked, running a soothing palm over Yuuji's abdomen and smiling when Yuuji's stomach reflexively sank, hips pulling away the closer his hand got to his sensitive cunt.
"T-Thank you, Daddy. Thank you, Daddy." Yuuji continued to repeat the words like a prayer as he panted, eyes closed.
"I want you to thank me every time you cum tonight. Understood???" Yuuji nodded his head immediately, earning a rough smack to his thigh.
"Ah! Yes, sir—Daddy! Yes, Daddy!" He redeemed, adrenaline coursing through him and he felt like he was on cloud 9 right then. His body was sore but God it felt amazing. Everything felt amazing until all too soon, that magic wand was back on his overly sensitive clit and yuuji almost screamed, instantly running from the overwhelming vibrations. It was way too much too soon. He couldn't take it. He just couldn't.
"No! I can't—Daddy I can't!" Yuuji cried, body trembling and writhing as pain mixed heavily with pleasure and confused all of his senses, his body running on instinct alone as it tried to get away.
"Come on baby. You can do it. You're doing so good. Take it for Daddy. Be Daddy's good boy." Sukuna soothed lovingly before sadistically turning up the vibrations a notch and basking in the beautiful screams emitting from his boy.
Yuuji's toes curled so tightly it was borderline painful as that awful pleasure crept back up on him again quicker this time, taking him by surprise. "Daddy! Can I please!" He screamed, hands fighting hard against their bindings as Yuuji rose off the bed once more, unable to speak properly.
"Yes baby. Give me another." Before Sukuna even finished talking, Yuuji was screaming, letting go completely and snapping like a bow as he came unglued under his Daddy's ministrations. Unlike before, It was immediately over stimulating and Sukuna didn't intend on giving him a break this time.
Yuuji panicked. Tears fell freely down his cheeks as he writhed painfully against the torturous pleasure. His cunt gushed slick beneath him and every time his pussy clenched, he felt the vibrations stronger against his pulsing clit.
"Daddy! Please ! Stop! Stop—hurts ! S'too much!" Yuuji slured, coughing between endless cries and moans as he choked on his own spit and drool. He felt like he was going to pass out. This was too much. He was getting scared.
Sukuna groaned, cock twitching painfully as it continued to soak through his briefs. He knew he was going too far for this to be their first time, but Yuuji hadn't said a color yet. He had to comfort him–to calm him down or Sukuna was positive he would yell red soon and end their session. He can fix this.
"Shh. Shh. Its okay baby. You're okay. Everything's fine. You're so strong for me. One more. Daddy just wants one more. You can do it. You look so perfect right now–so beautiful–so perfect for me." Sukuna's praise echod through Yuuji's rattled mind and overpowered his fear in a way he couldn't quite understand. He had to remind himself he wasn't in danger. Daddy would never really hurt him. This was a scene, and afterwards he would hold Yuuji with gentle hands and loving touches.
With a new kind of determination, Yuuji nodded, taking a deep, shuttering breath between gasps as he forced himself not to squirm so much and grit his teeth painfully, trying his best to handle the extreme overstimulation. The brilliant smile on his Daddy's face solidified his decision and made him feel more confident in it. Sukuna was elated that Yuuji had agreed to keep going but his inner sadism was roaring its ugly head as Yuuji tried to suppress his movement and be quieter. He couldn't have that. That was fine. Nothing wrong with a grand finale, he supposed.
Sukuna turned up the vibrations to the last notch, and waited for Yuuji's shocked scream and to quickly force two of his fingers deep inside of his drenched pussy, curving them upwards and began to finger fuck his hole at a torturous speed, nailing his g spot as he waved the wand over Yuuji's enlarged clit in small, rapid strokes.
The pleasure instantly outweighed the pain as Yuuji gasped so hard it hurt his chest, vision blacking out momentarily when he forgot to breathe. This was a new level of pleasure. Something addicting and terrifying at the same time; like the warnings people give you to not have sex on molly. Yuuji couldn't think anymore. He couldn't talk. He could only feel and force himself to breathe in short, sharp gasps as his body curled in on itself this time, strangling waves of body shaking pleasure rippling from his head to his toes in the best, most mind blowing ways possible as his orgasm tore through him at lightning speed, not being mindful enough to even care about rules or whatever punishment that might happen later at this point.
Yuuji felt something different with this orgasm though. Instead of clenching down tightly on Sukuna's fingers like he usually would, he felt his body push contractually until he was squirting like a fountain all over Sukuna, surprising the older who, without missing a beat, fucked him through it as he screamed his gratefulness. Sukuna and Yuuji had been together for almost a year at this point and they fucked like bunnies but he had never seen Yuuji do that .
He was so shocked he almost stopped, but the animalistic noises coming from Yuuji kept him on task as the boy howled and groaned, until shockingly, he squirted a second time, thoroughly soaking Sukuna and the bed beneath him before Sukuna finally decided now would be a good time to stop before Yuuji became dehydrated and actually did end up passing out. He removed his fingers, wiping them on the sheets and turned off the wand, setting it aside. He made quick work of releasing Yuuji from his confines and crawled into the bed, pulling the boy into his lap and kissing his head, doting lovingly on him.
"You did so well. So fucking good for me baby. I'm so proud of you—so lucky to have you. Thank you, baby. Thank you so much." He whispered, forcing his dazed and fucked out sub to drink the water he kept on hand until he was coherent enough to talk.
"'m I gettin' punished?" Yuuji slured quietly. Sukuna gave him a confused look for a moment before his eyes widened, and he couldn't stop the chuckle from leaving his throat.
"No baby. No you're not getting punished. You were absolutely perfect tonight. Now let's get you into the bath, yeah?"
Yuuji hummed contently, nodding slightly as he nuzzled into Sukunas chest and began to doze quickly. Yuuji can't wait to see what else Daddy will show him.
