KINKTOBER DAY 16: Sex Pollen (comm from 'Carmilla')
Izuku is hit by a sex pollen, but the teachers decide to keep it secret, because it shouldn't be too much of a distraction. Simply put, he'll be extremely aroused around the person he is most attracted to if he's near them.+

"Midoriya, my boy," All Might asks gently, fingers linked, arms resting on his knees. It's a weekend, and Izuku's mother is in the kitchen whilst Aizawa and All Might discuss the situation with him. School starts again tomorrow after a short break, so they need to sort this out +

today. "Is there anyone who might cause you extreme discomfort during your classes? Please do not feel embarrassed to tell us, we're here to help you."
Izuku chews his lip. His mind goes to Uraraka. He'd been continuously flustered by her in the first year, but then again, Mei +

and Melissa had sort of flustered him too. It wasn't so much /her/ as it was that girls hadn't... really talked to him before that. He pictures her face, round and smiling, and although he likes recalling his closest friends, it doesn't /do/ anything more than that. Apart from +

that... who is he most attracted to in class? It's kind of a difficult question. He's still not quite sure what his /type/ is, really. Everyone in class is beautiful in their own way! But no one particularly comes to mind when he thinks, 'who do I find /hot/?'.
"I-I don't think +

so!" Izuku tells him, fiddling with his fingers. "There's no one I can think of right away..."
"So it might not be an immediate issue," All Might says to Aizawa. The other hero doesn't look convinced.
"You've had a few weeks away from the dorms, being thrust back into that life +

might have you suddenly realising that you are attracted to one of your classmates. Still, All Might raises a fair point. We'll keep this between us until it wears off. If there are any... incidents, you will be briefly excused from class, and afterwards we will ask the +

individual to keep their distance for a few days."
Izuku nods.
"R-Right," he says, chewing his bottom lip a little more. "Sorry for the trouble!"
"Not at all," All Might smiles, and Aizawa nods. Izuku feels a little less anxious now. Even if something does happen, he'll be fine.+

***
The first day back in classes is always weird. It takes a while to get into routine, but when Izuku arrives at class bright and early on Monday morning, ready to capture the day ahead of him, he's sure nothing will go wrong. He already saw half of his class in the dorms +

yesterday evening (the people who weren't unpacking or asleep), and nothing had happened. It's likely that the person he's attracted to most isn't even at U.A., let alone in his class. He smiles to himself as he sits down, pulling out a brand-new notebook. Today'll be wonderful!+

He greets his class as they filter in, some in groups, some alone. He'd be talking to Iida and Uraraka, but they seem to be caught up in a private conversation. His smile only brightens as he watches them talk animatedly. There's definitely something between them, and Izuku's +

content seeing it blossom.
"Hi, Momo!" he says, as she walks by.
"Todoroki, Shinsou, hi!" he chirps.
"Hey, Kaminari, hey, Kirishima!" he greets.
"Mineta," he nods.
"Aoyama, I love the shirt!" he compliments.
"Good morning, Kacch-"
Izuku's mid-sentence when a tight, /painful/ +

knot in his lower stomach has him groaning and curling forward into his desk.
"You okay, nerd?" Kacchan asks, stepping closer. The knot tightens, and a sudden rush of /heat/ ripples through him. He can barely supress a moan. His thighs tremble as he clenches them together, +

forcing a smile onto his face as he looks up and says:
"I'm fine! Must've eaten... something..."
It's a /mistake/ looking up, because Kacchan is gazing back at him with soft concern written across his face. The sun paints a halo around him, with his broad chest and angular body +

and /ohhh/. Izuku's hole twitches; he can feel himself hardening in his pants. This is bad. This is awful. He's always thought of Kacchan as amazing, but he didn't know he felt it like /that/.
"Want me to take you to Recovery Girl or some shit?" Kacchan grunts, placing a hand +

on his forehead against the fever. A year ago, Izuku would've been caught off guard, but since he and Kacchan have become friends, Kacchan's quite tactile. No, what catches him off-guard is how the touch /scalds/ him, sending continuous waves of red-hot arousal rippling through +

him. Izuku can't help it this time; he whimpers softly, face flushed red. Kacchan just looks more concerned, leaning in /closer/, which he shouldn't do, this is really bad, Izuku should-
"Midoriya." Aizawa's voice is like fresh water as Kacchan steps away. "All Might would like +

to see you in his office. Everyone else, in your seats."
Izuku sighs a breath of relief, nodding at Aizawa and quietly slinking out of the room.
***
"This /is/ a problem," All Might agrees. "Had been anyone else, we would have simply asked them to stay away, but with it being +

young Bakugou, it will be entirely more difficult."
"I'm sorry, All Might," Izuku repeats, burying his face in his hands. Why did it have to be /Kacchan/ of all people? It makes perfect sense, but it's also going to /ruin/ their friendship.
"Do not fret, dear boy," All Might +

reassures, patting his shoulder. "I had suspected something for a while between the two of you, but this provides an opportunity for you to consider how you want to progress with him in light of your feelings. Friend or more, he is irreplaceable in your life. I have faith that +

the two of you will make it past this just fine. Don't fear, young man!"
Aizawa enters the room just as Deku manages a wobbly smile.
"I've made the necessary arrangements," he says. "You may come back to class, Midoriya."
"N-Necessary arrangements?" Izuku echoes, heart dropping+

as he swallows.
"I have moved the seating temporarily, and have informed Bakugou that it would be best to keep his distance for a few days, out of no fault of his own," Aizawa clarifies.
"Did you tell him it was a Quirk?" Izuku worries. If he didn't, he knows what Kacchan's +

going to be thinking: that Izuku doesn't want to be around him. And telling present Kacchan that is dangerous. Past Kacchan would've taken it as Izuku looking down on him, but present Kacchan only goes as far to call it 'un-fucking-acceptable', in his own words. Izuku had tried +

to avoid him /once/ after they became friends, when he was beating himself up for failing a practical exam and didn't want Kacchan's aggressive reassurances. The blond had ripped the dorms apart hunting him down, and when he did, he'd slung him over his shoulder and carried him +

to his room, proceeding to tickle the life out of Izuku. Afterwards, they'd marathoned the AM movies and Kacchan had made him repeat "I am boo boo the fool for putting myself down" ten times. And that was minor. This? He's trapped. Kacchan's going to find him, and when he does, +

(ugh, look at the tweet limit, having the audacity to /exist/)

Izuku's going to have to somehow explain himself before he dissolves into a wet, lewd mess and permanently embarrasses himself.
"I didn't tell him it was a Quirk, I didn't want to put pressure on you," Aizawa says. Izuku appreciates his kindness, but he's completely doomed.+

***
Izuku's currently pushing against the door with all the strength he has (which is a sizeable amount). Kacchan's broken the lock on his door and is now pounding at it with his fists. He hasn't used his Quirk yet, but Izuku doesn't think it's long before he /does/ blow the +

door right off its hinges.
"Deku, fucking open the hell up, what is /with/ you today!?" Kacchan yells through the door.
"I can't let you in, Kacchan, I don't want to!" Izuku shouts back with equal force. "Stop disturbing everyone and leave me alone, I'll explain in a few days!"+

"Like hell you will!" Kacchan roars. "We've got our evening sparring session tomorrow and on Thursday, we've got our movie night on Wednesday, we've got the arcade thing on Friday, and fuck if you're missing all that! I'm gonna smash you at every single thing /including/ +

watching movies, and I can't fucking do that if you don't move your ass and let me in!"
Izuku winces. Their schedules /do/ kind of revolve around each other.
"W-We can reschedule," Izuku says weakly, yelping at a particularly forceful shove almost throws him off balance. +

"Fuck that," Kacchan spits. "You let me in right now and explain your goddamn self or so help me I /will/ use my Quirk."
Izuku gulps. Kacchan's going to get in either way. He might as well keep his door intact in the process.
"Fine!" Izuku exclaims. "But you can't hold me +

accountable for anything!"
He moves away from the door and Kacchan immediately barges in, slamming the door behind him and pushing Izuku up against it, one hand on his waist and the other by his neck in the perfect kabedon. The effect is instantaneous: Izuku's leg buckle, weight+

supported entirely against Kacchan's body as he bites his lip to muffle a wanton moan.
"What the fuck?" Kacchan murmurs, keeping his grip on Izuku. Izuku pants, face red as he hardens in his trousers.
"Q-Quirk," he manages with a gasp. Kacchan blinks, before moving a hand to cup+

his face, gently tracing his jaw. Izuku's mouth falls open helplessly in a moan, and he chokes out, "K-Kacchan, w-what are you-mmff!?"
Izuku is silenced by two big fingers in his mouth. Kacchan rubs Izuku's lower lip with his thumb as Izuku salivates and moans around his +

fingers, tears springing to his eyes. Suddenly, Kacchan removes his fingers and steps back, sitting on the bed and sighing.
"It's an aphrodisiacal Quirk, isn't it?" Kacchan deduces. "Like sex pollen or something. Your mouth reacts to my touch even if you don't want it to, and +

your skin heats up wherever I touch it. Fuck, sorry for making you uncomfortable."
"I-It's okay, but-" Izuku needs to tell him that just moving away isn't enough, that he still feels his hole tighten just watching Kacchan lounge on the bed like he owns it, that he can't /look/ +

at him without a million different sexual fantasies filling his mind.
"What are the requirements?" Kacchan says, cutting Izuku off.
"R-Requirements?" Izuku swallows. "I-I don't know, I-"
"Bullshit, Aizawa targeted me for a reason, you're trying to stay away from me for a reason +

too," Kacchan points out. "I must be linked to the trigger. What is it? Oldest friend? Someone close to you? First person to touch you? Past... bully? I don't fucking know, tell me. And I'll know if you're lying, Deku, so don't even try it. I can handle it, whatever it is. Even +

if it's like 'someone you secretly hate' or something-"
"I-It would never be that!" Izuku cries angrily. Why would Kacchan even /say/ that!?
"Then what /is/ it?" Kacchan presses, and his demanding tone makes it hard to stand. Izuku wants to get on his knees and suck Kacchan's +

dick until he cums and-
"Attraction!" Izuku blurts out. "The person you're most sexually attracted to!"
The room is silent.
"You... You think of me like..." Kacchan says slowly, processing it. "Deku, do you fucking mean it?"
"O-Of course I do, I can't make it u-/ohhh/!" Izuku +

/does/ fall to his knees then, Kacchan rushing forward to catch him on reflex before considering what it'll do to Izuku. His hands steady under Izuku's ass, and Izuku's legs wrap around his waist as he buries his face in Kacchan's shoulder, moaning helplessly as his thighs +

trembles.
"K-Kacchan, please," he begs, hands curling into Kacchan's hair as he grinds forward against the blond. Kacchan moves backwards carefully, sitting them down on the bed with Izuku straddled in his lap as he supresses a groan of his own. "Kacchaaan, I need it, m-my body +

feels so /hot/, and I-I'm so /wet/, please, /please/!"
"What do you want me to do?" Kacchan whispers, pulling Izuku's face back as Izuku rolls his hips slowly against the blond, biting his lip at the friction.
"W-Want your cock," Izuku gasps, cheeks staining with tears as his +

body starts to grind faster against Kacchan's hardening cock on its own, his thick length slotting perfectly between Izuku's wet ass cheeks. "W-Want you to f-fuck my hole, Kacchan, /please/, I need it!"
"Then take it, baby," Kacchan says. "I'm not gonna do anything to you, +

because I don't know what you want when you're thinking clearly. But you can use me; my body belongs to /you/."
Later, when Izuku's mind isn't so hazy, recalling that statement makes his heart flip, but for now, it makes something /else/ flip in him as he immediately sinks to +

his knees, tugging Kacchan's trousers and underwear off in one go as Kacchan's thick, hard cock springs out, glistening. Izuku's mouth waters at how big it is, and he reaches out to stroke it a few times, marvelling at the size and girth. Kacchan groans, head tilting back as he +

lets Izuku use his dick however he wants. After a few strokes, Izuku leans forward, kitten licking from the tip down to the base and then kissing the head, before swirling the tip around his mouth. Kacchan bites his lip as Izuku slowly starts to take the whole, thick length in +

his mouth, looking up at Kacchan through his eyelashes as he does. The tip of it hits his throat and he gags lightly, but continues pushing until he's got all of it in his mouth. It's /heavy/, and Izuku moans at the sensation of having his mouth so filled. But it's still not +

enough; his whole body is on fire and he needs /more/. So he starts bobbing, carefully at first, the addictive feeling making him speed up as he deepthroats Kacchan's dick. Obscene sounds fill the air as Izuku groans and sucks Kacchan's dick like it's the best thing he's ever +

tasted. From the way that Kacchan grips the sheets, jaw tensed, he's close, and Izuku is too, leaning down to jerk his own leaking dick in time to his mouth as he fucks his mouth on Kacchan's cock.
"Ohh, Deku, pull out, I'm g-gonna-" Kacchan stutters, but Izuku only sucks +

(you know what really sucks? the fucking tweet limit)

/harder/, bobbing up and down as he brings Kacchan closer and closer to the edge. And then, as he moves a hand to stroke Kacchan's thighs as he continues his ministrations, Kacchan lurches forward, spurting cum into his mouth. Izuku pulls off quickly and moves to jerk Kacchan +

off so that some of the cum coats his freckled face. He licks his lips as he finishes, grinning up at Kacchan.
"Fuck, Deku, you look..." Kacchan breathes, but he struggles to finish the sentence, staring down in awe at Izuku. Izuku giggles and wipes the cum from his face, +

smearing it a little more over his cheeks as he rubs it away. He gets up quickly, turning around and forcing his trousers over his thick ass as he strips. Izuku hears the way Kacchan's breath catches in his throats as Izuku exposes his round ass, sitting back on the bed and +

hovering over Kacchan's aching cock. His body is /so hot/ all over, it's the only way he can describe it, and sparks of arousal rush through him as he reaches back to grip Kacchan's dick and /sinks down on it/ in one smooth move. He moans like a /whore/; Kacchan moans and +

gasps loudly, grabbing handfuls of Izuku's fat ass. Izuku hums and shakes his ass, soft moans slipping continuously from his lips as he twerks against Kacchan's thick cock, getting used to the sensation of his hole being so stuffed. It feels /good/ being so full, something he +

tells Kacchan as he starts to /bounce/, propelling himself up and down with those powerful thighs.
"Yesss, Kacchan, Kacchan, Kacchan, your cock is so /big/ and /thick/, I'm so fulll," Izuku gasps, mouth open in a pant, eyes rolling back as he grinds down and rides Kacchan's cock+

non-stop, picking the pace as Kacchan leans forward and moans loudly against him. He sounds /heavenly/, and his voice only turns Izuku on more as he lifts himself, changing the angle so that he can wreck his own prostate. He cries out when he hits it perfectly, picking up the +

pace and getting louder and louder as he fucks himself on Kacchan's thick cock. His ass jiggles against Kacchan's body, his cock leaking pre-cum as brings himself closer to orgasm.
"Yessss, more, more, /moreeee/," Izuku gasps, moaning like a pornstar as he swivels his hips and +

Kacchan's cock pounds against his prostate. He can feel his climax approaching, and when Kacchan digs his hands harder into Izuku's soft, overflowing ass, he knows Kacchan is close too. He moves his hands, one playing with his nipples whilst he jerks himself off desperately with+

the other, his rhythm growing sloppy as he relentlessly slams his ass against Kacchan's cock.
"I-I, I-I'm gonna, ohhhh- K-Kacchan, I'm g-gonna-" Izuku chokes out.
Kacchan pants out a "same, Deku, oh /fuck/," and as Izuku bounces harder and deeper, Kacchan tips into an orgasm, +

big, thick cock throbbing as he plugs Izuku fat ass up with cum. The feeling of being so thoroughly filled sends Izuku over the edge too, and he arches back, screaming Kacchan's name as he cums all over himself and Kacchan's thighs. He keeps bouncing his ass through his orgasm, +

Kacchan's overstimulated groans keeping him going until he's ridden it out. The heat fades from his body as he pulls off Kacchan's dick, turning to cuddle into his chest.
***
(It's embarrassing explaining how it wore off so soon, but Izuku's got Kacchan all to himself, now.)
