When He's Angry

Smut Warning
BottomKiri, TopBaku
They're older in this one and it's quirkless. Also it's my first smut fic so don't judge me.

Eijiro was angry. That's a rare emotion for him. Katsuki knew this, and was thoroughly scared. It's always scary when his sweetheart of a fiancé is angry. He was going to go out for the night, maybe run some errands, but Eijiro had different plans.
"Sit your ass down," his boyfriend said. He does as he's told, sitting down on the couch of their house. He's learned to listen when sweet Eijiro cusses. He tenses up a bit as his angry boyfriend climbs into his lap and straddles him, wrapping his arms around his neck.
"Uh...Ei? What are you doing?" Bakugou says, a light blush dusting his cheeks.
"I need to express this anger somehow, and I don't feel like punching a wall." He cups the back of Katsuki's head, raking his fingers through his hair.
Katsuki sighs and presses a soft kiss to his boyfriend's lips.
"What did you have in mind?" He says, wrapping his arms around Eijiro's waist, massaging the small of his back, trying to relax him. Eijiro reaches back and grabs Katsuki's hands.
"Just follow my lead," he says seductively, as he slides Katsuki's hands down to his rear, and leaving them there. He slides his hands up his boyfriend's chest, and around his neck, locking his fingers together and rubbing the sides of Katsuki's neck with his thumbs. Katsuki's cheeks flush pink as he cups his boyfriend's rear, as directed.
"Damn, you're fucking needy when you're angry." he says, smirking.
"Just shut up and kiss me, dammit." Eijiro says, pulling Katsuki in for a passionate kiss.
It takes a second, but Katsuki kisses back, gently squeezing his boyfriend's ass. Eijiro's cheeks flush pink and he lets out a small, breathy moan. He snakes a hand up Katsuki's shirt and starts feeling up his chest, while keeping his other hand on the back of his neck. The kiss separates for a moment, giving them a chance to breath. Eijiro doesn't let up. He leans in and starts kissing Katsuki's neck and jawline.
"Nngh...Ei..." Katsuki moans. This feels good. He closes his eyes and melts into his boyfriend's necking, then feels a sharp pain as Eijiro bites down on his neck. His breath hitches.
"Ow- hey!"
Eijiro feels a lump in Katsuki's pants press up against his crotch. He chuckles and licks the bite mark, making Katsuki shiver.
"Such a masochist," he says.
"Mmnh...S-shut up..." Katsuki moans. Eijiro pulls back and cups his flustered boyfriend's cheek. He runs his thumb over his bottom lip and pulls it down, then leans back in, kissing him passionately again. He grinds against the lump as he slips his tongue into his boyfriend's mouth. Katsuki is a bit surprised by this, but allows their tongues to connect, swirling with each other, combining their saliva.
"Ha...mmm..." his breathing becomes a bit heavy as he feels his body getting hotter, his pants getting tighter as Eijiro grinds against him. He feels a small lump in Eijiro's shorts pressing against his stomach.
"Ha...fu- ha...Ei..." he moans, squeezing his boyfriend's ass a bit harder.
"You're very excited, aren't you? You got bigger for me." Eijiro says coyly as he pulls back from the kiss, a line of saliva dribbling down from their lips.
"S-shut up...f-fucking hypocrite..." Katsuki breathes. Eijiro chuckles and pushes his boyfriend down so that he's laying back on the couch.
"What are you-" Katsuki is interrupted.
"Just relax," Eijiro says, pulling up his boyfriend's shirt and leaning down and kissing his chest, starting at his clavicles and slowly working his way down. "I'll take care of you, baby." Katsuki let's out a few soft moans and pleasured grunts, covering his mouth with the back of his hand. Eijiro moves down, covering Katsuki's chest and stomach with kisses. His hands snake downwards and stop at Katsuki's belt. He unbuckles it and undoes his pants, slowly pulling them down.
"W-wait...Ei..." Katsuki pleads. Eijiro humors him, gently running his fingers along the lump in his boyfriend's boxers, making him shiver.
"Ha...f-fuck...l-let me make you- ngh...feel good...t-too." He says, uncovering his mouth. The bulge in Eijiro's shorts gets bigger. He smirks and sits up on his knees, looking down at his boyfriend.
"You can help me prepare if you want, baby," he says seductively, making a circle with his index finger and his thumb and holding it up to his mouth, sticking his tongue through it. Katsuki smirks back, scoots himself up and leans against the arm of the couch.
"Mmm. Gimme your ass," he says, undressing his boyfriend with his eyes. Eijiro chuckles and gets off the couch. He feels himself up as he strips for his baby, leaving his shirt on. Katsuki watches and takes off his pants.
"You're such a fucking tease," Katsuki says, reaching into his boxers and easing himself up a bit. Eijiro comes back over and straddles Katsuki, facing away from him. He slips his hands into Katsuki's boxers and pulls them down, releasing his shaft, making it stand erect. He's already leaking a bit.
"Damn, baby. I made you this hard huh?" Eijiro says, leaning down and gently taking it in his hand.
"With how feisty you're being, it was hard not to be excited," Katsuki replies, grabbing Eijiro's rear again and pulling it towards him, spreading his cheeks with his thumbs. "You're already wet back here too." He starts giving him kisses all over his rear, and eating him out. Eijiro shivers and let's out a few soft, pleasured moans. He pulls Katsuki's shaft to the side and licks it, starting at the base and going up. He licks the precum off the head and sucks the tip a bit before letting it go further into his mouth, then in an out of his throat.
"Mmm fuck, you're so fucking good at that, Ei," Katsuki moans as he sucks on one of his fingers. "Your throat is so fucking tight." He traces Eijiro's hole before sliding his wet finger in, rubbing up inside him.
"Mmf- mmmnn..." Eijiro moans, still sucking Katsuki off. He wants more. Katsuki notices how fast he seems to be loosening up and sticks another finger in. He jolts a bit as Eijiro starts sucking him faster.
"E-Ei...gonna...c-cum...like that..." he says, letting out some pleasured moans, still fingering Eijiro's hole. Then it happens. He tenses up as he ejaculates inside Eijiro's throat.
"Ha...hah...sorry..." he breathes. He hears a slurping sound before Eijiro sits up and swallows. He turns to look at Katsuki, some white fluid dripping from his mouth. He licks his lips and wipes his mouth with the back of his hand.
"It's ok. I drank most of it," he says, smirking. "We wouldn't want to stain the couch." He turns around, now facing his boyfriend. He feels Katsuki's wet shaft rest against his ass. He's still hard. He reaches back and presses it into his crack, using his other hand to stroke himself. "I'm gonna ride you, ok?" He says, breathing a bit heavily as he jerks off.
"You're not done yet, and the condo-" Katsuki starts.
"Don't care. We're going rough and raw tonight, baby," Eijiro says, smiling coyly. Katsuki smiles up at him and sits up a bit. He cups his cheek and pulls him in for a kiss. Eijiro kisses him back then pushes him back down. He sits up on his knees and spreads his ass, then eases down onto Katsuki's dick. He let's go as he's penetrated by the head, then slides down, sucking Katsuki's dick into his wet ass.
"Ngh-ah! Ha ha...mmmnh," he moans as a chill runs up his spine. It hurts, but if feels so good.
"Ngh...fuck...tight..." Katsuki says.
"Hngh ah ha...I'm gonna- mm ah...move..." Eijiro says, rubbing the outside of his hole. Katsuki nods and Eijiro starts to slowly ride him, moving his hips and getting used to the rhythm, covering his mouth to muffle his moaning. Once he's got a rhythm down, he starts to move faster, moving his hips so that Katsuki's dick hits the right spot inside of him.
"Ha ha nngh ah...f-fuck!..." he moans, tears forming in the corners of his eyes from how much it hurts, shivering from how good it feels. Katsuki looks at his fiancé lovingly.
"You're so fucking beautiful and sexy Ei...let me hear your voice," he says, reaching up and grabbing his hand, pulling it away from his mouth. Eijiro slams down once more before stopping. His legs are getting tired, and he wants it faster. He pants, sticking his tongue out a bit, saliva dripping out of his mouth and running down his chin. He's trembling. Katsuki sits up and wraps his arms around his fiancé, pulling him close.
"Aw, Ei...are you sure this isn't too rough for you babe?" He says sympathetically, pressing soft kisses to his neck. Eijiro's ass feels so good, it's throbbing. He wants more. He cups Katsuki's cheeks and pulls him into a kiss, sliding his tongue inside his mouth once again. Katsuki kisses back, rubbing circles into his back. Once the kiss separates, Eijiro hooks his arms under Katsuki's, hugging him and gripping his shirt.
"B-baby...I want m-more..." he says, still trembling a little.
"More?" Katsuki repeats.
"Mhm...I want you to fuck me hard, a-and fast...p-please Katsuki..." he says, burying his face into his fiancé's shoulder. Amazing. He can go from being in control, to begging like a hungry dog.
"Ok Ei...wrap your legs around me," he says, moving his hands down to his thighs, grasping them firmly. Eijiro does as he's told, locking his ankles together behind Katsuki's back. Katsuki stands up, picking up his fiancé. He carries him across the room, being careful not to accidentally pull out, and braces him against a wall.
"I'll start slow. Ok?" Katsuki says, giving him gentle, but erotic kisses on his neck as he presses him into the wall.
"Ok..." Eijiro replies, squeezing his legs around him and clutching his shirt. Katsuki continues necking him and starts slowly thrusting into him, making Eijiro moan softly. After a minute, Eijiro asks him to go faster and he complies, cupping his rear with one hand and bracing his other on the wall.
"Ngh- mm...ha ah ha...b-baby...f-faster..." Eijiro begs, panting and salivating. Katsuki goes faster, pounding harder into him, and moving one of his legs up so that his shin rests on his shoulder. He keeps hitting Eijiro's prostate with every thrust.
"Ei...you feel good?" He asks between pleasured grunts. Eijiro claws at his back.
"Ah! Y-yes! Ha hah! A-amazing! You feel...so g-good...inside- A-ANH!" His moans of pleasure are louder and more frequent now. His ass feels amazing! He removes one hand from Katsuki's back and starts stroking himself.
"Agh- fuck...ha...I'm gonna c-cum..." Katsuki says, starting to slow down so he can pull out.
"Mnh! Me too...hah ah...d-don't stop...ah ha ha...I want it- ngh ah! ...f-fuck...inside! C-cum inside!" Eijiro pleads, arching his back as he gets closer. Katsuki nods and goes back to his previous speed, moving his fiancé's other leg into the same position as the first, panting like a dog. About 30 seconds later, they climax together. Eijiro's cum all over his shirt, while Katsuki's fills his hole and spills a bit, dripping onto the floor. They share a sweet kiss, both breathing heavily. Katsuki pulls out and carries Eijiro to the bathroom. Both of them are tired now, but Katsuki will still pamper his sweetheart of a fiancé. He sits down in the tub with him, taking their shirts off, and letting him lay back on his chest as he draws a warm bath. He washes them both, making sure there's almost no residue left. He even washes their hair, remembering to use Eijiro's tinted shampoo for his dyed red hair. Once they're done, he drains the tub and dries himself off, then wraps his sweetheart in a towel and carries him to the bedroom. He sets him down on the bed and gets dressed, putting on fresh boxers and pj pants. He gets a pair of boxers, pj pants, and a t-shirt out for Eijiro and starts dressing him, giving him lazy kisses on his stomach, shoulders, and cheeks. He lays down in the bed with him and pulls the covers up. He hugs his sleepy sweetheart close to his chest and gives him a lazy kiss on the top of his head. He whispers an 'I love you' before the both of them fall asleep. The next morning, Eijiro wakes up sore from the waist down. Katsuki isn't in the bed, but the curtains are open, letting the morning sunlight spill into the room. He sits up and yawns, rubbing his eyes.
"Good morning, Ei," says Katsuki, coming into the bedroom with a breakfast tray.
"Mmm. Morning," Eijiro replies, smiling.
Katsuki sets the breakfast tray over his fiancé's legs and sits on the bed. He's made him a plate of strawberry pancakes, and his protein drink.
"I figured you'd be fucking sore, so I called you in sick from work, and called myself in from work so I could stay and fucking take care of you. I've already cleaned up the living room from last night, and when you're done eating, I'll massage your back," Katsuki explains. Eijiro smiles and starts digging into the pancakes.
"Thanks, Katsuki," he says, taking a bite.
"You feel better now?" Katsuki asks.
"Yeah. I'm not mad any more, but I'm sore from the waist down," he chuckles.
"You asked for it, Ei," Katsuki says smugly. Eijiro laughs a little and kisses his cheek.
"You take such good care of me," he says, smiling.
"Damn fucking right I do," Katsuki replies, going to sit next to his fiancé. He pulls out his phone and starts scrolling through his notifications. Once Eijiro is done with his breakfast, he sets the tray aside and snuggles into his fiancé's chest, watching him scroll through his phone. Katsuki puts his free arm around him and kisses his forehead. They stay like that for awhile, just enjoying each other's company. It's a good thing they're getting married. They're meant for each other.

Oof I didn't realize how long that one was. Hope you enjoyed it.
