"Tie me up. Use me."

For a moment, everything is silent, Hizashi pausing where he's sitting straddling Shouta's hips, hands pinning his wrists to the pillow above his head.
Shouta pauses too, looking like he's just as shocked by what came out of him.
Well, Hizashi had asked what he wanted.

He'd drawn back from a particularly intense kiss, taken a second to look down at Shouta's face--panting and pupils wide--and said, in his best 'you're going to obey me' voice, "Tell me what you want."
And Shouta had obeyed beautifully.

It's only a beat before Hizashi smiles, even as he lets go of Shouta's wrists to cup his face, kissing him sweet and tender.
When he breaks away, Shouta pouts, annoyed that he's being gentle now. "Hizashi--"
"Shh," Hizashi says, smiling at him again.

He puts his finger to Shouta's lips, a featherlight touch on kiss-reddened flesh.
"I'm going to take care of you."

"Hizashi--" Shouta starts again, but breaks off at the Look Hizashi gives him.
"I said 'Shh'. No arguing," he orders, and Shouta shuts up.

"Now," he says, climbing off Shouta and off the bed, "take your clothes off and wait here for me. I'll be right back."

"I just--" Shouta starts again, sitting up, and Hizashi turns back to him, fond disapproval in his eyes as he grabs Shouta's chin.

"Hey. Just let me take of you, okay? All you need to do is follow orders. I think they're pretty easy so far, right? You can be a good boy, can't you?"

Shouta doesn't break eye contact, so he can see when the worried lines around his eyes ease. "Okay," he says quietly.

Hizashi smiles. "Good." He lets go of Shouta's chin to run both hands through his hair. "I know you can be good for me." He leans in to give Shouta a quick kiss.

"Just wait here, and I'll be right back."

Five minutes later, Hizashi comes back into the room to the sight of Shouta, naked and sitting on the bed. He hadn't specified how he wanted him to sit, so he's just comfortably crosslegged, waiting patiently.

He smiles, then makes a happy noise at the pile of neatly-folded clothes at the foot of the bed. "Good job," he purrs, and Shouta watches him as he start laying things on the bed.
A thick strip of black cloth. A metal bar with loops at both ends. A coil of red rope.

First, the cloth goes over Shouta's eyes, knotted securely at the back of his head.
Then, the ropes. Through words and gentle guiding touches, Hizashi tells Shouta how he wants him, pulling his arms behind his back. The rope he winds around his wrists, tying them together.

The rope carefully gets wound up his arms to his elbows, knotted together until he has no space to move.
Hizashi gets Shouta's knees up to his chest, then starts the rope tying his ankles to his thighs, then winding the rope around his legs.

When he reaches his knees, the two ends of the rope go through the ends of the metal bar, keeping his legs apart.

Hizashi moves back, just enough to see his handiwork. "There. How does that feel?"

Shouta shifts around, moving carefully until he's kneeling.

It's a whole process. He has to rock forward onto his front and then get his legs underneath himself without any use of his arms, then raise himself up. Someone with less core strength wouldn't have been able to do that much, and it's clearly not easy for Shouta.

"Feels good," Shouta finally says.

Hizashi nods, even though Shouta can't see him. "Describe it."

"Can't move. I can't use my arms, can't see. I can't stand up. I can't go anywhere. I can't get away. I can't even close my legs," he says, voice low and labored.

"I don't know where you are."

"I'm right here, baby," Hizashi coos, leaning in to kiss him. "You can't stop me from doing this," he says, yanking Shouta's head back by his hair, making him hiss out in pain, "Or this," he says, his hand caressing up his thigh.

(Not that he wants him to stop, but that's the point. Another point: of course he can, with just a word.)

"No," Shouta says, but it just sounds like he's agreeing. "I want you to--"

"Hey," Hizashi says sharply, clapping a hand over his mouth.

"I asked you what you wanted, and now I'm going to do that. You wanted to feel *used*. That means your input doesn't matter. Hold your applause until the end," he jokes a little more lightly. "For now, just sit back and let me do what I want."
"Not that you have a choice."

(to be finished later or perhaps tomorrow!)

Shouta just makes a choked noise, biting on his lip as Hizashi's fingers slowly inch up his thigh. When they find their target, teasing over slick folds, Hizashi is treated not just to that feeling but the sight of Shouta's mouth falling open, a soft sound escaping.

He makes more sounds as he slips his fingers inside him, all sweet like he doesn't know that he's making noise at all. Maybe one of these times he'll try adding his nice pair of noise-canceling headphones, see what kinds of noises Shouta will make if he can't hear himself.

For now, he just smiles and praises, "You're doing so good."

"This is what I want to do," he says, when Shouta's eyebrows knit together again like he's going to argue. "If I want to be gentle, I'll be gentle. If I feel like being rough, I'll be rough."

When Shouta's face slackens, care falling away, Hizashi knows he has him where he wants him.

He pulls his hand back, and a hand on the back of Shouta's neck is all the warning he gets before Hizashi is pushing him down on his front.

He hits the bed hard, face-first, unable to stop himself with his arms, and all he can do is turn his head to breath. He wiggles around, trying to get up as much as he can again, but Hizashi stops him with a hand on his shoulderblades.

Shouta lets out a breath and goes slack, and it's only a moment of unbuckling a belt and the noise of a zipper against his panted breath before Hizashi is pushing inside him, filling him in one swift motion until the rough denim of his jeans is pressed against Shouta's bare skin.

Shouta gives a choked moan, and he squeezes around Hizashi, trying to pull him deeper or just make him move, but he stays still. "Feel this?" he says, low, hands stroking over Shouta's sides, running over the ropes crisscrossing his arms. "Feel me?"

"You're going to," he promises, and gives no more warning before he starts a rough, brutal pace, hips moving like a jackhammer.

"Fuck," Shouta gasps, writhing on the bed. His hands open and close until his fingers are digging into his palms.

His legs tense, muscles shaking as he fights against rope and metal--to no avail.

"Fuck," he chants again, "fuck, fuck..." His eyes are squeezed tight shut, and his voice is starting to sound desperate, almost a whine.

The way he tenses, gripping down on Hizashi again, is familiar, and Hizashi laughs. "Are you going to come? I haven't even touched you!"
Shouta just whines into the pillow, and Hizashi continues, fingers digging into his forcibly-spread thighs.

"Huh? You gonna get off just from me using you like a toy?"

Shouta cries out, a broken muffled noise, and his walls flutter around Hizashi, making him groan too. "I'm not stopping," he warns, grabbing Shouta's hips hard enough to bruise and moving faster.

Shouta is even more verbal now, constant moans spilling out of his mouth, babbling out barely-coherent nonsense. "Oh god, please, Hizashi, ah fuck..."

He might have lasted a little longer than his boyfriend, but it's not much longer before Hizashi is chasing his own release,

and then only a few moments before he growls, grinding his hips into Shouta's as he comes.

And then it's all different, and yet not. Hizashi murmuring praises as he deftly undoes knots, kissing pretty red lines left behind. Shouta stretching out carefully, still breathing hard.

The blindfold comes off last, and Hizashi smiles like it's the first time he's seen his love's face. "Did that feel good? Was that what you wanted?"

Shouta's smile is tired, his eyes half-lidded and satisfied. He doesn't even need to say, "Yeah," but he does.

Hizashi had been fully dressed, but now he stands up for a moment to strip off his shirt and jeans before flopping back down into bed. Shouta curls around him, and Hizashi strokes his hair, draws lazy patterns across his back.

"Thanks," Shouta mumbles into his chest.

"Of course!" Hizashi chirps, kissing the top of his head. "I love you."

"Love you too," Shouta says, rubbing his face against Hizashi.
