Work Text:

Katsuki watched a drunk woman leave the bar and didn’t think anything of it. It was when he saw two men signalling to each other and then leaving the bar did he start to think something.

He put his glass down and paid the bartender before going outside in search of the girl and the men.

He hears voices in an alleyway and goes to check. Unsurprisingly, the girl is being cornered by two men bigger than her in height and size.

Although she’s drunk, she’s clearly not stupid. She’s refusing to go with the men and constantly trying to escape from their hands.

Katsuki steps in before things get dirty. The two men, upon seeing his face, drop their tough guy persona and try to make up excuses for their actions. Katsuki isn’t hearing any of it.

He feeds each of them with a hard right to the face before taking the girl out front.

“Stay here. I’m going to get you water.”

He goes inside the bar and returns with a sealed bottle of water. The girl is crouching on the sidewalk, huddled over what looks to be her own vomit.

“Here, drink this. It’s sealed.” He hands her the bottle and watches as she chugs almost half before stopping.

“Is there anyone coming for you?” He really hopes that she didn’t come here alone or that she had a friend picking her up.

“No– *hic*”

Great.

“Can I go with you mister?”

What?

Katsuki is stunned. The correct thing to do would be to call a cab to take her home. Or call a friend to pick her up.

“No.” He firmly replies.

The girl stands up fully, looking up at him with her big watery green eyes. “Please?” She drawls. “I’ll be scared if I go alone.” She pouts.

Katsuki can’t bear the thought of her getting assaulted by more creeps so he reluctantly agrees.

He calls a cab to take them both back to his house. The girl, who he still doesn’t know the name of, is clinging to his arm with her head on his shoulder.

She’s slouched all up in his personal space and he has to restrain himself from pushing her away. She’s not in her right mind.

The cab comes to a stop outside his modernly fancy house. Tipping the driver generously, he helps the girl out of the cab and leads her inside. He gives her a glass of warm water while he makes his way to the guest room.

She stumbles after him. “This is where you’ll be staying till morning.”

“Ah thank you- what’s your name?”

“Katsuki.”

“Nice to meet you, I’m Izuku.”

Her words are still slurred but easier to understand now that she’s sobered up a little. “Yeah. Night.”

He turns and walks to his own room, not bothering to shower and just changes into comfortable clothes and slips under the blanket.

He’s on the tightrope of sleep and wake when he hears his bedroom door open. Not too much time has passed so it’s sensible to think that Izuku can’t fall asleep that fast on a drunk mind.

“Kat-suki?” He doesn’t respond. Maybe if she thinks he’s asleep she’ll go back to the guest room.

Seconds pass by without Katsuki hearing another sound. He assumes she went back.

Until he feels a small hand on his chest.

“Woah..” Her voice is soft and he almost doesn’t hear her.

Her hand dips lower, mapping out the shape of his abs before getting to the waistband of his sleep shorts. Her hand glides further to the soft print of his cock before he jumps up.

“What do you think you’re doing?” he questions as he grabs her hand.

“Ah- please- please let me suck-” A hiccup cuts her off.

She doesn’t need to finish her sentence, Katsuki can already guess what she wants. “No.”

Her face turns into a pout as she tries to free her hand. “Why not? I want to thank you for saving me.”

“Thank me by going to sleep. In the guest room.” he lets go of her hand, hoping that she turns around and leaves but she doesn’t.

Her hand moves back to Katsuki’s print and she squeezes it.

Holy fuck.

Katsuki’s mind blanks once that happens. “Go back to the room Izuku.” His voice holds no more authority as he asks one final time. Closing his eyes and laying back on the bed.

Izuku uses this opportunity to get on the bed with him and lean over so her mouth is near the bulge.

“But I really want to taste you Katsuki.”

She pulls his shorts and boxers down, allowing his hardening cock to spring out and almost hit her in the face. “So big…” she mutters in awe.

“Izuku-” She cuts him off by giving him a soft lick at the bulbous head. Her hand holds his shaft steady as she starts peppering kisses all over it.

Katsuki can’t help but think he’s doing something wrong by allowing a drunk girl to suck his cock but he makes no move to physically stop her. It’s not that he doesn’t want it, he’s actually well overdue for a good fuck, but the break in his celibacy streak being broken by a girl who looks way younger than him while she’s drunk isn’t exactly the scenario he had planned in his mind.

While he’s spiraling in his thoughts Izuku picks up the pace. Her hand moves rapidly up and down the shaft as her lips wrap around the head and she starts digging her tongue into the slit.

Katsuki’s groans of pleasure get more audible as he fights to not show any signs he’s enjoying this.

While he seems to be suffering, Izuku is having the time of her life babbling sentences to him.

“You taste so good.”
“You’re so big.”
“I might choke.”

Her babbling makes her saliva drip out of her mouth, down her chin and down the length of Katsuki’s cock making the slide of her hand wetter.

As she gets comfortable with just the tip she removes her hand and allows herself to sink down on his cock. She’s breathing harshly through her nose as she looks at Katsuki through hooded eyes.

Katsuki pulls her off for breath and she’s coughing up spit and precum all over his cock.

“Fuck my throat please.”

Well if she’s asking for it how could he refuse?

He guides her mouth back onto his cock and takes a hold of her hair as he slowly works more and more of himself into her small waiting mouth. Even when she begins to gag he doesn’t pull out, just lets her adjust to the added size before continuing on.

His hips gradually buck up to meet her mouth as he finds a steady rhythm to follow. She’s moaning and gagging around him hunched over his cock swallowing it like its food. He takes this time to look down at her properly.

She’s still in the same skimpy clothes she wore to the bar. She obviously wasn’t expecting to be at Katsuki’s house and intended to go back home at the end of the night. But things happen.

Her top is backless with only strings to tie around her neck and her waist. The skirt she’s wearing is so short he’s able to see the white cotton panties she has on.

He feels himself getting close to an orgasm so he informs her. She pulls off his cock, spit dripping from it as it plops down heavy and wet on Katsuki’s abdomen. “Please cum in my mouth.” Before she goes back down on him.

How can he deny her that?

He continues on with the quick pace he had before.

Izuku looks a mess. Mascara and eyeliner running down her freckles cheeks, spit covering the bottom half of her face as her teary eyes look up at Katsuki.

Just looking at how wrecked she is already is enough to push him over the edge. He cums in thick spurts down Izuku’s throat. She moans as she swallows it all, enjoying the slightly salty taste of him.

He pulls her off his cock allowing her to gasp for breath as she sits back on her heels.

“Can you go again?” Katsuki just came and she’s asking for round two already.

“Please? My pussy is so wet..” she mumbles.

Despite just cumming, Katsuki’s cock twitches in interest. Izuku takes that as a yes.

She moves off the bed to remove her panties before straddling Katsuki’s hips. He can feel the dampness of her bare pussy as she rests on his abdomen.

She reaches a hand behind her, grabbing Katsuki’s cock and leading it to her wet cunt. With no prep and no resistance, she sinks down all the way to the base. The moan she lets out is pornographic. Her cunt flutters rapidly around Katsuki’s cock, trying to get used to the size as he tries not to buck his hips.

Once izuku properly adjusts and the stretch becomes pleasurable she starts moving. Slowly at first, bouncing up and down and grinding in little circles.

Katsuki lets out some low moans of his own. Izuku was so tight, almost like a virgin.

Once Izuku picks up her bouncing he meets her hips halfway. They’re both moaning in unison, Izuku louder than Katsuki as the pleasure rapidly builds.

Izuku brings her hand down to rub at her clit in quick circles as she loses the rhythm of her bouncing. Katsuki makes up for it by holding her hips and slamming his cock up into her.

She cums in no time, and as much as Katsuki would love to see Izuku’s pussy dripping with his hot seed, he’d rather not get her pregnant during a one night stand.

He pulls out as the last of her spasms subside and ends up cumming on his abdomen again, adding to the mess of spit and Izuku’s slick.

Finally exhausted, Izuku lays next to Katsuki instead of going back to the guest room.

Katsuki sighs as he watches her drift off. He’s going to have one hell of a morning conversation.
