It’s not news to him that you like the feeling of his hand around your throat.
He’s been playing around with the idea for a while, now, whenever he’s touching you—just in subtle ways.
Whenever he kisses you, he places his hand just above your collarbone—not fully on your neck, but the tease is there—and slots his lips between yours with a sigh.
Or it’s when you two are out in public and it’s a little too busy and you easily become lost in the crowd—Tsukishima guides you with his hand wrapping delicately against your nape, keeping you close while he has you in his hold.
He always picked up on the way you reacted whenever he touched you there.
How blown your pupils would get.
How your breath would hitch with your lips parting with a small intake of breath.
How dazed you would look in the eyes—making him feel just a little smug about finding out a little secret about you that he plans to use one night.
It’s when he’s got you lying on the bed all pretty for him—looking up at him with starry eyes as he pumps two of his fingers in and out of your drenched pussy—with his other hand caressing your cheek, his thumb teasing your lower lip.
And he’s smirking down at you—in his usual lackadaisical way— with one of his knees sitting between your bent legs as he presses the pad of his thumb down onto your lower lip to pry your mouth open. “You always need something to suck on, don’t you?”
He teases you, his voice low and mirthful, and all it does is make your pussy clench as you moan—rolling your tongue out to flick it at his thumb before wrapping your warm mouth around it, your cheeks hollowing as you give his thumb a slow, indulgent suck.
“Shit,” It’s the way you keep eye contact with him as your head moves, leaving his thumb shiny with your saliva as you suck it, that sends heat down to his cock, making him feel light in the head. “You’re a needy little thing, you know.”
You make a sound that’s similar to a moan around his thumb, and your eyes flutter, going half-mast, as you bob your head and swirl your tongue around his thumb as if it was his cock instead.
And Tsukishima can’t help it—you look so desperate like this, your back arching against his hovering body, looking up at him so obediently, with your tits all perked up and nipples pert and pretty as you leak all over his hand—
It’s filthy and you—
“A perfect little slut,” Tsukishima lets those words slip out, a groan in his throat, and you choke a little with a whimper when you feel him press his thumb into your mouth a bit deeper, affection lacing his rather filthy words.
And you moan—low and wanting—when you hear him call you that, and Tsukishima can’t help but chuckle darkly as he leans in a little closer, his head tilting almost mockingly as he watches you with desire and affection. “Yeah?”
He curls his fingers to rub your spongey g-spot, his palm pressing against your swollen little clit for friction that sends heat up your tummy and chest. “You like being a little slut for me, sweetheart?”
Fuck.
“Looking like the mess that you are just because of me,” Tsukishima hums, his voice low. “You can hear just how soaked you are, you know.”
You whine around his thumb as your orgasm balances at the edge—ready to combust with how tight your muscles feel—and you nod.
God—you’re too perfect for him.
He can’t help the small smile that threatens to creep up on him, trying to focus on making you cum—for the second time tonight—on his fingers before he finally fucks you the way you both need him to and—
And then his eyes widen a little, turning more amorous when his eyes briefly flit down to your exposed throat—
“…You can get a little more messy for me, right baby?” It’s not a question.
Just a warning worded more sweetly.
Because before you even get a chance to respond to him—
You feel his thumb slip out of your mouth—making a wet popping sound with your spit connecting a thin, clear string from your mouth to his thumb, leaving you gasping for air—
Only for it to be partially taken away again when you feel long, calloused fingers gently wrap around the area just beneath your jawline—and your eyes widen as you look at him, your breath catching, and he watches you with a knowing look behind his eyes.
Like he knows that no matter what—you’ll trust him.
And he’s not wrong—you do.
Enough to let your eyes immediately soften into submission, your lips wet from your saliva, and you let out a small moan as you tilt your chin up—giving him more room for his fingers to hold and cover.
It brings out a hiss from him, low and breathy, and you see the way things primarily shift in his eyes when you begin to pant, moving your hips as he fucks you with his fingers—encouraging him to push harder and make you lose your mind.
And god—he listens almost instantly as he squeezes the sides of your neck a little more, and you moan as you get a little hazy in the head, your limbs loose as his fingers move inside you.
“Fuck, look at you,” Tsukishima lets out a small breath that’s almost a chuckle, and he watches you with his dick throbbing as you let him take the weakest part of your body into his own hands to play with.
Giving him that trust that gets him all heady and needy to just—
To just kiss you and fuck you and take all of you until all you feel, smell, taste, and hear is him.
“Always so good for me, sweetheart.”
He grinds his palm against your clit with more pressure, moving it in circles as his fingers get swallowed by your pulsing walls—and then he’s pressing his fingers into your pulse points a little more, slowly playing with your ability to breathe, feeling his hand heavy around your neck until—
“Oh fuck—Kei—shit—”
You gasp, shaky, and your lower spine draws tight when your eyes get blurry from the brief lack of air—and that seems to snap something deep within you as you cum furiously around his fingers, spasming and gasping with your senses turning numb—
“Just like that, baby—get all nasty for me—“
Tsukishima finger fucks you through it, watching with dark eyes as he loosens up his fingers around your throat—and clear fluids squirt out of your sopping pussy with every thrust of his wrist inside you.
You end up gushing fluids all over the bed and his thighs—but Tsukishima doesn’t care.
He’s too wound up and high on watching you cum on him to care about how sticky everything is—
It’ll only get messier once he gets his dick inside you anyway.
You cry, coming down from your high as air rushes into your lungs after your orgasm—your pussy clenching hard from wave after wave of pleasure—
“I’m going to fuck you now, okay?” You hear him breathe that out. “And fill you up just how you like it.”
You’re still too out of it to respond with anything other than a languid nod, feeling light and a puddle of fire at the same time as he kisses you so achingly soft that you melt against him.
