Here Are Some Boyfriend Headcanons About Yu...

…because he is literally so perfect and I am completely obsessed with 100% of him 100% of the time..

Genre: Fluff, Smut MDNI 18+

Warnings: Explicit sexual content, Dominance, Edging, Overstimulation, Light choking, Spitting, Cum play, Possessiveness

SFW

• He’s not over-the-top with PDA, but his hands are always on you. A thumb on your hip when you’re standing next to him. A palm on your lower back when you’re walking through a crowd. It’s never loud, but it’s always there.

• When he talks to you, his voice naturally drops. He doesn’t do it on purpose, but when it’s just the two of you, it sounds deeper. Slower. Almost lazy. You live for it.

• He listens more than he talks. But when he does speak? It’s something sharp, soft, or too honest—“You looked so good today I forgot what I was doing for a second.” And then he’s back to sipping his drink like he didn’t just mess you up.

• Yu likes having you close, but he’s not clingy. He’ll sit next to you in silence for hours—legs brushing, pinky hooked around yours—completely content. But if you shift away, he notices. And pulls you right back.

• He’s observant as hell. You don’t even have to say you’re upset—he’ll see it. “What happened?” No fluff. No pressure. Just the space to let it out if you want to.

• You steal his clothes and he lets you—doesn’t even say anything. But if you wear something of his out, he’s watching you all night. Doesn’t hide it. He likes it when people know who you belong to.

• He’s quiet until someone flirts with you. Then his hand finds your thigh under the table, firm grip. “They done?” he’ll ask without even looking. Just calm. Sure of himself. Sure of you.

NSFW

• Yu doesn’t just have a high sex drive—he has stamina. Quiet, unshakable, lethal stamina. One round is never enough. He’ll pull out, flip you, slide back in, and say, “Not done,” like you didn’t just come twice already.

• He’ll keep you on the edge on purpose. Fingers deep, lips brushing your ear, voice flat: “Don’t cum yet.” And if you do? He pulls away and leaves you twitching, overstimulated, untouched, until you’re begging again.

• When you ride him, he watches everything. Doesn’t touch—just lets you use him, arms behind his head like it’s nothing. “Go ahead,” he says, like he’s letting you work for it. Like he knows you’ll fall apart first. You always do.

• He likes holding you down. One hand locked around your throat—not squeezing, just firm. Thumb under your chin to keep your eyes on him. “Look at me,” he says while fucking you slow. “That’s it. Watch yourself fall apart.”

• He spits in your mouth sometimes. No warning. Just leans in, thumb on your chin, and lets it drip. “Swallow.” His voice doesn’t change—but your whole body does.

• Yu’s the type to edge you with just his fingers until you’re sobbing, then press his forehead to yours and whisper, “One more.” And you give it to him. Even when it hurts. Even when you’re shaking. Especially then.

• He’ll cum on your stomach just to watch it drip. Rake his fingers through it. Drag it across your clit to keep you sensitive. Then slide two fingers back inside like, “Still open for me. Good girl.”

• When you’re too fucked out to answer, he smirks. Slaps your thigh once—light but firm. “Use your words.” And if you still can’t speak, he slows down. “You want more?” Another stroke. “Say it.” Another. Until you do.

• And afterward? He doesn’t rush to clean you up. He spreads you open with one hand and just stares, lips parted, breath calm. “You should see yourself right now.” Then dips his fingers back in just to feel it one more time.

headcanon: fluff

for yu nishinoyas birthday, happy birthday bud

you were waiting outside the gym for noya to finish up with practice thinking of the best way to surprise him

but he beat you to it

yu had hugged you from behind and then greeted you

just by looking you could tell he was extra happy about being able to spend his birthday with you 

now he didn’t want to do anything supper special so both of you decided to just go the Sakanoshita Market and eat nikuman

as you were walking and listening to one of his most recently updated playlists, you were also holding his pinky and ring finger

but the music playing wasn't enough to keep him from asking about your day and also telling you about his 

and with that he also couldn’t stop blushing from the idea of being this close to you

now you were about to step into the store, when noya gave you another hug but this time not from behind and with more affection than before

he was showing a more vulnerable side that you only saw maybe three times before and it caught you of guard but you didn't say anything, however, yu did break the silence 

“thank you for today,” he then went silent again but then said under his breath “damn, i really do love you”

your face inevitably followed the flushing of his into a bright red and responded with “i really do love you too”

once you had stopped talking to each other you noticed ukai staring at you and noya with disappointment that you both could have just waited to be alone and not in front of his store

but he didn’t scold you, instead he gave you both half off nikuman since noya did well in practice and it was his birthday

after finishing them, noya had walked you back to his house so you could celebrate with everyone else and the whole time yu stayed by your side and held your hand wall you wore his shirt and talked with saeko
