For a few hours, you and Tsukki study together and review the material. Once you're done, you both quietly review to yourselves. You lay on Tsukishima's bed while he sits at his desk. After a while, you realize you are no longer retaining any more information. You look up and see Tsukishima studying as though he's right in the middle of learning. You continue observing him as you take in his handsome features. You smile to yourself thinking of how lucky that you are to be with him, although he does piss you off a lot. You shake off your thoughts and try to get in a bit more studying since he's still working, but you just aren't learning anything new.

"Ugh," you groan as you put your head down in your notebook, "this sucks."

"Are you confused about something?" Tsukishima asks.

You pick yourself up and shake your head no.

"You got any more of those cute mnemonics to help me?" you say a bit flirtatiously.

"No," he says unbothered as he turns his head back to his notebook.

"Tsukki," you whine "no fair."

"No fair?" he says quickly turning his head back over to you.

You stare at him in shock since he got so worked up over that.

"I let you into my house and helped you study," he lectures "I could have-"

"Yeah I know," you mumble "but now we're just reviewing separately and it's no fun anymore."

Tsukishima closes his notebook and turns himself around to face you.

"I can walk you home now if you want, Y/N," he calmly tells you.

"Uh, n-no that's not what I was saying," you stutter as you feel blush dust across your face.

"What did you want then?" he asks while looking genuinely confused.

"Well, I thought maybe we could hang out together," you reply as you give him a nervous smile.

Tsukishima groans and you immediately close your notebook.

"Is that a yes, Tsukki?" you ask happily.

"Yeah whatever, but don't call me that," he tells you.

You give him a huge smile and jump off his bed. You put away your notebook and turn back to him.

"So what's there to do in your house?" you shrug.

You watch as Tsukishima puts away his notebook and then sits on his bed.

"I dunno."

"Well," you say as you sit down next to him, "I'm sure you can think of something."

Tsukishima leans his head against the wall and stares up at the ceiling.

"Tsukki," you pout at him "I'm bored."

Tsukishima looks back at you and you feel your stomach turn. You can't help but think back to when he kissed you yesterday. You watch as he stares back up at his ceiling and bite your lip.

"Can I ask you something?" you ask as you scoot closer to him.

"Sure," he says in a bored tone.

"Why did you kiss me yesterday?"

Tsukishima continues to look up at his ceiling. You watch him, hoping some kind of body language will give you any kind of positive response.

"I wanted to make sure you knew not to do that with anyone else besides me," he says as he tilts his head to look at you.

You feel your face heat up and get chills the second he looks over at you.

"How did you find out-"

"That Kuroo kissed you? Don't worry about it, it doesn't really matter since now you know not to do it again."

As you stare into Tsukishima's eyes, you see a different look on his face. Immediately you bite your lip, trying to come up with an excuse without being too flustered.

"I-I'm sorry I didn't mean-"

You're interrupted by Tsukishima suddenly slamming you down on his bed. You look up to see him laying on top of you, pinning your arms on either side of your head. You try to say anything to him, but you're way too flustered.

Is he going to...

"So tell me," he says in a deeper voice than usual "did you learn your lesson."

You nod, unable to make any other noises or movements. You watch as his classic smirk extends across his lips.

"T-Tsukki," you mutter.

As you call out to him, he lets go of you and sits up.

"Sorry," he says as he looks down "I got too carried away."

"Huh?!" you ask surprised.

I thought for sure he was going to make a move on me.

As Tsukishima continues to stare down towards the floor, you sit up and place your hand on his cheek.

"You don't have to apologize for that. I just wasn't expecting it, that's all," you smile.

You turn his face to look towards your own. You gaze into his eyes a moment before leaning in to kiss him. Immediately you feel how soft his lips are. Tsukki gently touches your bottom lip with his tongue and you allow him an entrance. You slowly lean back until you're laying down with him on top of you. You put your wrist in his hands and he slams them down against the bed again, causing you to take a sharp breath in. Tsukki tilts back a bit and takes in your body underneath his. He then leans back in and kisses your neck. As he gets near your ear you hear him whisper to you.

"If I fuck you until you can't walk I'll know for sure you've learned your lesson."

As chills once again go through your body, you feel his hands squeeze your wrists tighter.

"P-Prove it."

Tsukki lowers himself to kissing your neck. He lets his hands roam your body as you let out soft moans. He puts a hand to your back and sits you up on the bed. You pick your arms up as he lifts of your shirt and then you do the same to him. He then unsnaps your bra and pushes you back down on his bed. He continues kissing you and grabs one of your breasts. As you softly moan again he smirks down at you and moves his head down to suck on your bud while his other hand continues to squeeze your other breast.

"Tsukki," you whisper "your door's locked, right?"

"Yes," he groans, a bit annoyed at my question.

Tsukki moves his hand down from your breast to your inner thigh, causing you to whimper out to him. He looks up at you, watching your completely flustered face. You watch as he backs away and pulls off your skirt. He then picks up your legs and places his head between them. You feel as he shifts your panties to the side before licking your clit. He was starting out gently.

You bite your lip as you slightly squirm at the sensation. Tsukki spreads your legs further apart and lifts them slightly more. He begins sucking deeper than before.

"Tsukki," you moan out while reaching closer to your finish, "I'm gonna-"

Your voice trails off as he comes back up over top of you.

"Sit up," he says as he gets off of you.

As you sit, you watch him grab a condom from his desk and place it on his bed. The second you see it, you freeze.

He's really going to...

Your thoughts are interrupted as you watch Tsukishima unzip his pants and place them over his chair. He then proceeds to take off his glasses.

As he gets back on his bed, he grabs you to sit on him, but you don't move.

"No," you smirk to him.

You take a hair-tie from your wrist and pull your hair back into a ponytail. You get off the bed and kneel between Tsukishima's legs. You give him another slight grin as you grab the sides of his boxers. He helps you pull them off and you throw them to the side. After, you take your panties off as well. You take in his length for a moment before spitting into your hand.

You look up at him as you place your hand onto his shaft. You watch as the lust builds up in his eyes. As you continue to stroke him faster, he grunts out your name. You pause for a second when you hear him do that, as it takes you off guard. Tsukki uses this moment to grab you and pull you up towards him. You straddle him and he beings to attack your neck again.

You look to your side and see the condom on the bed. You grab it and rip it open.

"Do you want to?" Tsukki asks in between kisses.

"Of course I do," you say before giving him another kiss.

Tsukishima grabs onto your sides as you lift yourself up from him. You stroke your hand down his length, allowing the condom to fit over him. You align him to your entrance and sit down, taking him in.

"Fuck," he groans breathlessly.

You begin to grind yourself on his lap as you put your head onto his neck. You begin to leave a few hickies on his neck while you're there. You feel Tsukishima slide his hand down to your ass. His other hand turns you to face him. You watch as a grin forms on his face before feeling a hard smack on your ass. Your breath hitches and Tsukki takes the moment to grab your face. You allow him to kiss you as you continue to push yourself deeper into him.

As you take in all of Tsukishima, you let your head fall back. He grabs your waist and helps you get deeper inside of him. You let out a scream as you feel your orgasm building.

"Cum on me," Tsukishima growls.

You wrap your arms around Tsukishima's neck and pull him in closer to you as you reach your finish. You let your mouth open as you do, but only your breath escapes. You move your arms so your hands rest on his shoulders. You watch as he finishes shortly after, noticing how incredibly sexy he looks when he does.

Tsukishima pushes you down on the bed and kisses you gently. As he pulls away, you watch him get up to throw out his condom. You try to stand up, but your legs are really weak. Tsukki laughs as he sees you struggling.

"Stop trying to move around," he tells you "do you need something?"

"O-Oh well I should probably get dressed and go home."

Tsukishima throws you one of his huge shirts.

"Just stay over."

"Are you sure?"

"It's not like you can walk home anyway," he teases.

"Right," you mumble.

You reach down and grab your phone from off the floor.

"I'll just tell Keishin I'm staying at a friend's house."

"Like he'll believe that," Tsukki laughs.

"Shut up!" you say as you text your brother.

You put your phone back down once you're done and tell Tsukishima to come lay with you. Both of you get under the covers and you wrap your arms around him.

"Goodnight, Y/N," he whispers before kissing your forehead.

"Night," you mutter as you pull yourself closer to him.
