Request: Tsukishima precious little stepsister decided to help him out by releasing some of the stress he's had, could you also add a breeding kink in there ?
I completely forgot about the breeding kink bit halfway through so I apologize for that but I’ve done quite a few breeding kink drabbles.
Warnings: incest, creampie, mean comments (but I wouldn’t consider it degradation? I’ll tag it just in case), College AU, fingering, edging
Kei-nii + relieving stress
With finals approaching and practices at volleyball getting more intense, Kei spends most of his time inside his room, studying, when he’s at home. You only see him when he gets food, taking his dinner back to his room to continue studying. If he’s not at home, he’s spending extra hours practicing at the gym. Whenever you see him, and you look at how tense his shoulders are, you always try to reach out to him. But he always has clipped words to say to you, you immediately backing off as he continues doing what he does. He’s always been like this, ever since your father married his mom.
Your mom tried to explain he’s always been this way, telling you he’s just stressed and the best thing to do is support him from the sidelines. Despite her advice, you wish to be of more help. He’s never shown he liked you, so you figured the best way to support was to stay out of his way and his sight, but you really wanted to help him. Talking a bit more with Akiteru, you realized that perhaps Kei just needs someone to silently be with him, rather than talk to him.
Well, what better way to silently help then offer hugs or even cuddles? A massage could work, too! With a pep in your step, you go up to Kei’s room and gently knock, him opening the door shortly after. “Oh, food. Thanks.” Short and clipped, like usual.
“Yes! Uh, I also wanted to, um, offer some support,” you start by saying, looking at your hands near your skirt. Still haven’t changed from your day clothes, you feel more self-conscious in the attire than your pajamas.
“Oh? Again? Didn’t I already tell you I didn’t need your help or support? I need to study,” he narrows his eyes, you can feel them on you. But you hold your ground.
“I thought you could use some cuddles, so I figured I’d offer my body as support. I’m not as smart as you, so I figured you wouldn’t need my help in that department. Or!” You get a little loud, startling him. “I could give you a massage,” you’re a bit more confident in your tone now, waiting for his response. After a moment, he sighs.
“Fine. I’ll accept your kind offer, dear sister of mine,” he slowly moves out of the way. “Lay on the bed,” he commands. His tone… it’s a bit different from before. You do what he says, however, laying down on the bed and waiting for him to lay down beside you. “So, I can technically use your body however I see fit, correct?” He sits between your legs, making you nervous.
“Um, yeah!” You decide to not try and correct him it’s only cuddles, hoping this will make him like you more. It’s been years, but you hope he’ll finally see you as a proper sister. “Which ever way benefits you the most,”
“Perfect,” he smirks, flipping your skirt up to see your panties. “I need to relieve some stress, anyways,” he continues, but you don’t stop him, hands slowly coming to his arms. “You can touch me, I won’t hurt you. Just no nail scratches. I have a game on Saturday,”
“O-Okay,” you say, letting his lips trail against your throat as his long fingers dive into your panties, pushing themselves into you only to find wetness.
“Oh? Seems like someone thought of another way. Cuddles and massages? A bad excuse for trying to make your offer less taboo, I suppose,” he continues to talk, wiggling his fingers inside before rubbing against your walls, feeling you squirm from the sensation. “You seem to enjoy that. Desperate much?”
“N-No! I’m not desperate,” you try to reason, but his face is in front of yours and your words get caught in your throat.
“Desperate for your big brother to actually show interest in you? That’s it, isn’t it? You’re not very subtle, you know,” he explains, so uninterested as if he isn’t currently fingering your cunt. Attempts to bite back are easily dying, pressure against your walls getting too much until you’re completely arching off his bed, riding a high— then it’s gone. “Not quite yet. You need to wait for me, dear sister.”
You respond by moaning, feeling his fingers pulling your panties down and tossing them somewhere else. The air brushes against your wet entrance, making you shiver. Something warm presses against it almost immediately, however, only to rub against your sensitive nerves. “Kei…”
“Be patient. You’re so needy,” he looks down at you, finding you to be in a state of disarray, satisfied with himself. Pushing his cock into you, you have to bite your hand to keep from being too loud, knowing Akiteru’s room isn’t too far from Kei’s. Kei doesn’t make you wait too long to start thrusting, finding himself just as needy and desperate as you.
Sounds escape your lips, teeth removing themselves from your thumb to give the skin a break, but you can keep quiet. Kei momentarily stops, flipping you over so your face is in the pillows, continuing his rhythm. Harsh slaps against your ass having you screaming into the pillows, feeling him put himself over you to brace himself, thrusts getting harder and sloppier with each one.
“You gonna cum? Gotta wait for me, you know?” His tone is mocking, a warning that if you try to finish first, he’ll punish you. The possibility has you clenching around him, a cry as you find release on his cock. “I didn’t say to fucking cum,” he practically growls, a few more harsh thrusts before he pushes his entire cock inside, finishing inside. “Take it all,”
“N-Not inside—“ you try to say, but your voice is weak and hoarse from muffled screams and cries. It’s too late, but you can’t find it in yourself to care when Kei presses a kiss to your head.
“Thank you. The best sister I could ask for,” he whispers. Before you can say anything back, he does another thrust. “Oh? You thought we were done? I have 54 minutes left of my hour break. We have plenty of time to relieve stress. Get ready.”
