Summary
     Ochaco takes what she wants from him.
     Bakugou thinks he's in control.
Notes
     written for my friend Indy.
     Inspired by this_fanart by the wonderful Syblatortue.

.
It all started after the Sports Festival.
 
Bakugou had never taken notice of her before. To be fair, he hadn't really
taken notice of anyone until the Sports Festival. He hadn't even paid attention
to his classmates quirks, but he did remember hers.
The gravity girl. The one who could make things float, Uraraka Ochaco.
And fuck if she didn't put up a good fight. The only problem is, she just gave
out right when things were getting good, leaving Bakugou wanting more.
But somewhere along the way things got out of hand.
It's how he finds himself after classes have ended one day, lining up his bare
cock with her entrance and pushing in. She moans, all fingers but her pinkies
gripping tightly around the edges of the desk where her front is pressed flush
against it. Her rear hangs off the side and he clutches at her hips, squeezing
in through the tight heat until he can see his pubes kissing her lips. They're
shiny with her slick and swollen, evidence of her guilt. She's been thinking
about this all day, just as he has.
She's so fucking wet and she clenches around him when he doesn't start moving
right away.
“Hurry,” She says quietly, voice breathless, little brows pinched as she looks
over her shoulder at him. “Before somebody catches us.”
Bakugou grits his teeth, winding a free hand into her hair and tugs, snapping
her head back sharply. She hisses, struggling against his grip to glare at him.
He smirks at her, though it's more of a grimace with the way his lips pull back
over his teeth, like a wild dog ready to snarl.
Soft fingers wind back to graze against his thigh and he pauses, glancing down.
They're all touching him except the pinky, which is poised a mere centimeter
above the skin. His eyes flicker back to meet hers, where her delicate mouth
hikes up at the edges. His mouth closes, lips pursing.
So that's the game she wants to play. He can humor her.
Gently, he unwinds his fingers from her hair, sliding them down until his hand
fits in the curve of her lower back. He pulls back until only the head remains
inside and thrusts back in, pushing her hips against the desk roughly. Her ass
cheeks jiggle from the impact and she cries out.
“Yes,” She pants, “Right there.”
Fuck you, bitch, he wants to say. She's lucky he's even giving her the time of
day. He doesn't need her approval, Bakugou knows he's hot shit, anyone with
eyes would want to fuck him if given the chance.
He fucks into her then, starts out rough and hard, cock bottoming out with each
thrust but she doesn't seem to mind, in fact it looks like the opposite. Every
slide of his cock through her slick heat draws a sharp gasp from her. She
grinds back against him, and when she comes it's with a broken “Bakugou!~”,
pussy squeezing around his shaft repeatedly until it pushes him over the edge.
He pulls out and shoots his load on her ass, painting her pale cheeks in soft
white.
She kinda looks beautiful. Maybe he'll put up with her being a little bossy if
this is the result.
 
.
.
.
 
The bus ride to the training camp was supposed to be a time for Bakugou to
unwind and relax before what would surely be a week of hell. He took his seat
near the back away from everyone else, sat his bag on the seat next to him and
turned towards the window.
Don't bother me, is the message he was going for.
But then sweet rosy cheeks approached at some point during the ride, small
hands picked the bag up and shoved it in the overhead bin and a round, pert
behind took its place.
 
Ochaco has her legs spread underneath the blanket she brought with her and he's
two fingers knuckle deep in her. Her silky folds are so drenched they make a
squelching sound every time he moves his hand and he should be cautious,
someone like Jirou or Shouji might hear, but every time he goes to remove his
hand she squeezes her thighs together and traps him.
(And to be honest? It's fucking hot.)
He moves his fingers, slow and deliberately, mapping out the grooves and
indentations in her walls, committing them to memory. If he's going to finger
this girl, he's gonna do it well, and he needs to know what he's working with.
When he comes across a rough nub he presses into it and she gasps.
Iida glances back at them from where he's sitting two rows ahead and Ochaco
smiles sweetly at him before turning to look at Bakugou.
She speaks in a quiet, casual tone. “I just thought of something!” She leans
in, Iida still watching with a critical eye, and whispers in his ear, “I wanna
taste you.”
Bakugou comes in his pants.
 
.
.

Someone tugs on his wrist before he's even fully awake, tugging him out of the
boy's room and outside into the brisk night air of the camp grounds. It's not
until they're both out of the lights and nearing the edge of the woods that he
stops.
“What the fuck are you doing?” He hisses, shoving his hands deep in the pockets
of his sleep pants.
She sidles up to him, pressing her chest against his front, teeth digging into
her soft pink lips. “I'm horny and I can't sleep.”
He shoves her off, but not forcefully. “That sounds like a you problem.”
Ochaco presses back against him unperturbed, this time wrapping her arms around
his middle. “But you can help me.” She whines softly, looking up at him through
her lashes. Her big doe eyes shine in the floodlights, her perpetual blush
growing darker as a hand roams down to cup the curve of Bakugou's ass. He sucks
in a breath, lip curling back over his teeth, and he's about to tell her to
fuck off again – he's tired - when she leans up on her tip toes and lightly
licks just above the collar of his tank top along the dip between his pecs.
“I'll ride you,” She says with complete innocence, “you won't even have to do
anything.”
He guesses he can allow that. “Fine.” He grumbles, and Ochaco is already
pulling him back to the woods, crossing the threshold and shrouding them in
nothing but the moonlight peeking through the trees.
They walk a little farther out, still close enough to the camp they can see the
floodlights but far enough away no one can see them through the thicket. Ochaco
pushes him down to sit against a tree and he lets her, pulling out his cock as
she shimmies out of her shorts. He's already hard just thinking about it, and
he wishes he had enough presence of mind earlier to grab his phone because he'd
love to get some pictures of her stretched around his cock, but before he can
even start to build on the images in his head she's sinking on his cock
already.
His hips snap up instinctively, filling her up. It's just as tight and hot and
soaking as he remembers, but before he can move again her hand is on his chest,
pinning him.
“Just let me-” She starts, cutting herself off with a moan as she cants her
hips up. She grinds her pelvis, rubbing her clit against him with each down
thrust.
Bakugou fumbles with the straps of her tank top and pulls the straps down her
arms. Her breasts spring free and he cups them, relishing in the way they
jiggle in his palms soft and plump as she bounces on his dick. She's still
pinning him against the tree with one hand, eyes squeezed shut in concentration
and Bakugou's eyes wander over her face to her breasts and down to her pussy
where it clings to his dick. She's so fucking gorgeous and riding him so well,
if she hadn't told him she was a virgin before their first time he wouldn't
have believed it.
“Fuck, girl,” He grunts, “Ride me,” and grips her hips, only to have her shove
his hands away.
Her eyes are still closed, brows furrowed. “Shhh, I'm almost there.” She places
her hands back on his chest, head falling forward. “Just – hold still.”
His cheeks burn with indignation and he's this close to shoving her off when
she slams her hips down, walls clenching around the base of his cock. She
clamps a hand over her mouth, smothering her own scream, hips erratically
jerking and rubbing against his lap, a flood of wet heat drenching him where
they're connected.
Fuck, he's coated in her juices but he won't complain about that, instead he
starts to rock his own hips up into her. He's so close, watching her soft
curves bouncing and moving over him, feeling her come on his cock, it's all so
much.
But Ochaco climbs off then, his dick slapping against his stomach wetly as she
extracts herself.
“What the fuck?” He snaps, reaching for her hips again. “I wasn't done.”
The bitch has the audacity to look surprised. “Oh!” She looks down at his cock,
still straining and red and now shiny with her. “Sorry, that's so rude of me.
Here-” And she takes his dick in her hand and starts pumping him so hard and
fast he lurches forward, curling in around her fist. He grabs her arm – this
isn't what he had in mind – but before he can manage to form words he feels his
balls drawing up and his cum spurting out, landing on the soft earth beneath
them.
It was utterly underwhelming. The way Ochaco smiles at him after, though, he
can't find it in him to stay mad at her.
 
.
.
.
 
Her slick brushes against his chin, and his tongue follows after, seeking out
her flavor.
Her waist is poised above his head where it's laid on the pillow in his dorm
room, panties discarded on the floor and skirt hiked up around her waist,
completely exposed to him.
“Bakugou-kun~” She sighs, lowering herself just enough so the tip of his tongue
can dip between her folds. “So impatient.”
His fingers tighten their hold around her thighs, squeezing in the soft meat.
Ochaco's body is so soft, that it's easy to forget how hard her spirit can
rage.
“You wanted to do this,” He snaps back, and her head tips back with a quiet
moan when she feels his hot breath fan over her cunt. “So, hurry the fuck up,
before someone catches us.” He finishes, throwing her words back at her. They
both that's not a real concern right now, no one is going to come busting in
Bakugou's dorm room even if he had left the door unlocked, but that's not the
point. He only agreed to all this to see her squirm, to prove he can be good at
anything he sets his mind too. Including eating pussy.
She lowers herself all the way then, settling down until her thighs are on
either side of his face, wet lips parting around his nose and mouth, and she
sighs. He pokes his tongue out and licks a slow, fat line from her hole to her
clit.
“Oh – Kacchan!”
He digs his fingers into her thighs then, harder, eyes flickering up over her
mound to meet her teasing smile. Knock that off he warns with his glare, but he
doesn't stop working his tongue, lips and teeth grazing over the sensitive
flesh. Her thighs quiver around his head and she sinks down farther, pressing
against Bakugou's face to where all he can smell and taste is her.
Her taste is sweet but mild, the scent feminine and enticing, and Bakugou finds
himself shutting his eyes then, giving into the feeling of her on his tongue,
her flavor filling his mouth. Her juices smear all across his cheeks and chin
as he licks, concentrating on a little stiff collection of nerves at her apex.
When he nips at it, she shudders, hands going down to grab his hair.
“Right there!” She gasps.
He works the spot over and over, ignoring the way she pulls on his blond locks,
ignoring the way she grinds down on him insistently – he pays attention only to
her taste and the sweet little noises she makes, high-pitched and airy.
“Good boy,” She croons, petting his hair when he seems to have found a
particularly satisfying rhythm. Her hips still and she lets him lap, the
fingers in his hair tightening painfully. “Don't you dare stop,” She tries to
threaten, but it comes out in a moan and he grins against her clit. His jaw
aches, his dick is straining in his pants untouched, but he presses on
unrelenting in search for more.
“Oh, Kacchan!” She cries, releasing his hair to stroke up her body and cup her
own breasts through her shirt. “Ah~ Kacchan, Kacchan!~” She's biting her lip,
head thrown back in ecstasy, and the sight goes straight to Bakugou's dick. He
starts thrusting his hips up into the air, seeking something, anything, to take
the edge off. She needs to stop calling him that, but the way it rolls off her
tongue sounds so good.
He sputters with anger he doesn't really feel, trying to peel her pussy off of
his mouth long enough to tell her to shut up with the nickname but her thighs
clamp harder around him. With a shout she grinds down, rubbing her clit against
his teeth and tongue, coming all over his face, soaking him with her fluids.
He hears the sound of a camera shutter and Ochaco climbs off as she tugs her
skirt back down. When he sits up, licking his lips and wiping his mouth with
the back of his hand, she's holding her phone up with the screen facing him.
Displayed is a picture of him, pale hair fanned out on his pillow and Ochaco's
soft thick thighs on either side, nose down obscured by her pubic mound. His
eyes are shut and his brows creased up like he's savoring a fine meal, her
slick smeared on his upper cheeks.
She brings the phone to her chest just as he jerks out to take it from her and
her hand pushes him away, and suddenly he's airborne, looking down at her from
somewhere half way between the bed and the ceiling.
“Goddammit, let me down, Round Face!”
She giggles, tucking the phone in the pocket of her skirt and stands off the
bed. “I will, don't worry.”
He flails his arms and legs, struggling against nothing, and the bubble of
anger he felt before explodes within him and makes his face burn. He lowers his
voice dangerously. “What are you going to do with that picture?”
“Nothing.” She answers innocently, eyes blinking owlishly. “I just like the way
you look with a mouthful of my pussy.”
He clenches his jaw. “Put me down.”
“Nuh uh, I'm not stupid, Bakugou-kun. Or should I keep calling you Kacchan?”
Her gaze travels down the length of his body, stopping at where precum has
moistened the crotch of his pants. “You seemed to like that.”
Small explosions pop off in his palm, but he's useless up here. He growls in
frustration, narrowing his eyes at her. She gives a cloying smile and opens the
door.
“I'll let you back down in a bit.” She motions at the bed, “I suggest not
struggling too much, so your landing is soft. See you in class tomorrow!”
Bakugou remains stuck like for another five minutes.
Ochaco left her panties on the floor.
When he finally lands on his bed with a soft thud, bouncing up and down, his
cock is still hard. That bitch left him hanging, though admittedly he wouldn't
want to jerk off someone who's threatening to blow him up, either.
He takes the panties from the floor and lifts them to his nose, inhaling deep
and flooding his senses with her scent of her arousal. His cock throbs and he
takes it out, stroking himself to completion, the wet panties still held to his
nose.

Bakugou's gonna make her choke on his dick.
Smug bitch wouldn't stop giving him a knowing look every time Deku called him
'Kacchan' in class today, going so far as to even call him that herself, a
barely contained smile playing at her lips the whole time. He hates it, but now
when he hears that stupid nickname he can't think of anything but having
Ochaco's delectable cunt on his face and he finds himself with a stiffy in the
middle of math class.
So he texts her to meet him by the bathrooms over by the sparring grounds and
as soon as classes are over he books it there and waits inside the boy's
bathroom. He expects her to show up right after – if how riled up she was the
last time is any indication of how badly she wants him – but he ends up waiting
close to ten minutes before she shows up, light footsteps echoing against the
tiled wall.
“Bakugou-kun?” She calls, and then he's rounding the corner to grab her arm and
drag her into a stall, sitting her down on the toilet seat. He's got his pants
down and dick out a second later and presses the head against her lips.
“Suck.” He says simply. Her eyes flash up at him, and she drags her finger –
all except the pinkies, a veiled threat – up his thighs until she grasps his
cock.
That stupid smile, the one that scrunches up her eyes adorably and widens her
round cheeks, shows up, and she gives a small nod. “OK, Kacchan~” She coos, and
then she buries his dick to the base in her mouth.
Bakugou's cock twitches, the wet heat enveloping him so suddenly and strongly
that for a moment he's not sure he can stay on his feet. He braces a hand
against the stall and looks down at her with wide eyes, marveling at how such a
small tight little mouth can take so much of him. Her tongue swirls as she bobs
back and forth, her locks of hair swaying and a strand sticks to his shaft
where it's wet with spit. She pulls back with a pop, a line of saliva still
connecting her lips to his tip. There's a glint in her eye.
“I wanna try something.” She says.
He bares his teeth, “Just suck my dick.”
“You'll like it, I promise.” She huffs.
“You said that about the other thing.”
“And did you not like it? I want my panties back, by the way.”
His cock is aching, and he can't deny her anything, not when she looks at him
like that. He purses his lips and nods, glancing away. “Fine.”
She smiles, lips stretching around his cock once again as she swallows him
down. Then something prods his asshole.
He hisses, hips jerking forward on reflex and Ochaco gags around his dick where
it's gone too far back, and holy fuck he's pretty sure he could come just
looking at that. It's just enough distraction that she's able to worm an index
finger between his cheeks again and push it past his tight ring of muscle. It's
dry and it drags on the way in, and Bakugou wraps a hand around her neck in
retaliation. He squeezes just the slightest, but doesn't fight her or pull away
when her finger presses in deeper.
It feels weird, like something should definitely not be going in that way, but
Ochaco seems to notice his discomfort and she starts rocking back and forth
over his dick faster, taking him deeper. Her throat constricts around his cock
head when she sucks him all the way in, and the dual sensation – of fucking
into something while something fucks into him – is unexpectedly pleasant. He
lifts a foot on the toilet to give her better access and relaxes, lets her take
care of him.
And boy does she fucking take care of him. She slips her finger farther inside
him and seeks out a bundle of nerves different from the rest, and when she pets
her finger over it Bakugou thinks he's been shocked. He doubles over, bracing
himself against the stall, pupils blown wide and a sound he's never made before
in his life pulled out of him. Ochaco seems to take it as some kind of
encouragement and she repeats the action, stroking over his prostate again and
again while she sucks and slurps along his cock, and the next thing Bakugou
knows is he's coming, painting the inside of her mouth with his spunk.
He's puffing and cursing and moaning and god, this has gotten out of hand, he
doesn't feel like himself at all when he's around this girl. He feels so
strange, so different, like he'd do anything just to watch her squirm and cream
her panties. It's not like him at all, and he hates it.
But after he comes he doesn't argue or fight back when she takes his fingers
and shoves them up her dripping hole.
 
.
.
.
 
Bakugou's on all fours stretched open on the bed. Ochaco's pink teddy bear
stares at him where it's propped up along the wall, and he feels the bed shift
behind him. The snap of a lid opening, and then the cold trickle of lube
hitting and sliding down his ass crack makes his spine straighten. A thin
finger smears the fluid around his hole where it's pulled tight around the
strap-on, and he shivers when it moves. He feels so full.
He's sure he looks a mess right now and he's grateful Ochaco can't see his face
from her position behind him, but when she starts to snap her hips against him
again, thrusting the huge dildo deep inside he realizes it doesn't matter.
Bakugou is wailing louder than he's ever made her, he's choking on noises that
are half-moan and half-sob, spit drooling down his chin as his eyes roll to the
back of his head. His asshole is on fire, burning as it stretches impossibly
wide, but when it brushes against his sweet spot it makes it all better.
“Does that feel good, Kacchan?” She asks in a sickeningly sweet pitch, delicate
hands gripping his narrow hips tightly.
He nods, but groans out a “Fuck you” anyway. She may own his ass, his dick, and
his heart, but she doesn't own his spirit.
(Not yet, anyway)
He earns a smack on the ass for the back-talk. He loves the sting.
Ochaco goes slow, takes him apart on her own time, and Bakugou comes untouched,
crying out her name so loud everyone in the dorms must hear his pathetic
submission. As the delirium from his orgasm dispels, he feels her wiping away
the sweat from his brow, rubbing the pad of her thumb across his cheekbone in
an almost tender manner.
She's whispering soothing words to him, “You were so good for me, Bakugou-kun,
you're the best at this. When you've recovered, I have a reward for you.”
He's laying on the bed, eyelids heavy with lethargy, and her words smooth out
the crinkle in his brow, make his eternal frown even out. She appears before
him with the strap-on removed, naked body flush with excitement, nipples hard.
He can see her thighs slick with her desire for him.
“Open your mouth,” She smiles at him, and swings a leg around to straddle his
head.
When she sinks down, he's smiling back.
