Chapter Text
Katsuki for a really long time had no idea how to get her sexual frustrations out. She knew what masturbating was but she just couldn't bring herself to do it.
She was only in the eighth grade but she knew that she developed late. Her tits where so small last year that you could call her a boy. But now a days, her chest is so filled out that she can feel eyes on her everywhere she goes. Even shitty deku stares at them when they talk.
Katsuki also learned that most people start to touch themselves at around nine or ten, so she felt like she was losing that stupid battle. So, she decided to ask the first person that came to mind. Deku.
She still remembers when she was ten and went to his house to hang, and when inko let her in, she said that izuku was not coming out of his room, which katsuki said was stupid but she was actually worried. So as soon as she walked in, there deku was, touching himself. It only made katsuki blush as he yelled sorry over and over when she left and walked home.
It was kind of funny when ten year old katsuki didn't look izuku in the eyes for over a month. Even when her parents took them to dinner at there house, she still couldn't do it.
So when katsuki was about to leave school, she walked up to izuku who was in his locker, probably grabbing his things. "Shitty deku, I need help."
"Oh, hi, with what kacchan."
"Teach me how to masturbate." Katsuki swore she saw izukus soul leave his body. "I know what it is but I dont know how to do it."
"I dont think you can kacchan, your a girl." Izuku said with his face a full shade of red
"What the fucks that supposed to mean!" Katsuki yelled. What the hell did deku know, he wasn't female.
"Well, you um you dont have a...penis."
"Fucking so what, just because I dont have a stupid cock doesn't mean I can't touch myself. Woman have things that make them feel good! Right?"
"Well, I dont know, but I dont think its, possible for you kacchan."
"Oh ill fucking show you its possible."
"What."
"Shut the fuck up you bitch." Katsuki then punched izuku slightly in the shoulder. If he said she couldn't, she would find out how to do it and record herself and show his shitty ass.
On katsukis way home, she looked up how woman masturbate and read everything she could on what to do. She read up on everything and when she got home she would do it.
As soon as she got home, katsuki took her shoes off and ran up stairs, dismissing her moms attempts to get her for dinner.
Katsuki sate down on her bed and looked up videos on masturbating. She found a website that she clicked on that sent her to a video on what to do and the steps to doing it.
The girl in the video said that she would need to take off her pants. So katsuki grabbed the rim of her skirt and lifted up her legs and slowly took it off. The next step for some reason was her shirt, but the woman said it was optional so katsuki left her shirt on. Then she said the most important part was to take your panties off. Katsuki blushed a little at that but did as told. She slowly took off her panties until she felt the cold air on her still smooth pussy. She hadn't grown any hair yet and she kind of wondered why.
The next thing the woman said was to spread her legs and touch her clit, but of course, katsuki had no idea what her clit was so she kept her eyes on the video as she spread her legs. The woman then touched her small nub and said to rub how you like. Katsuki still barely knew what she was doing but that didn't let it stop her as she did as told. She put her middle finger on her own little nub and started to rub.
Katsuki didn't really feel good yet but she kept going. The woman said that that was it but she said she would cum before she turned the video off. Katsuki didn't know what that ment so she just stopped watching.
The next thing she did was pull up her camera and record. She didn't say anything as she minuvered her camera to stand up on a toy on her bed. She then laid back as she started back up again.
She rubbed at her clitortoise for about five minutes before she felt something. It was okay at this point but she was now starting to blush as she sped up her finger. About ten minutes later, katsuki was a moaning mess. Her hair was now sticking to her forehead and he right arm was covering her eyes as she kept going as fast she could before a weird unfamiliar heat made its way down to her abdomen. She stopped for a second as she felt something in her clitortoise, but she missed the feeling and kept going. But before she knew it, the feeling was back and her eyes rolled into the back of her head as her pussy clenched and her hole squeezed around nothing. She was panting as the feeling went away.
Katsuki laid there for a while before she stopped the video. She then got up and grabbed her panties and skirt. She put her panties back on but put her skirt away in the top of her dresser. She started to change and grabbed her sweat pants and tank top from her middle drawer.
She made her way down to the living room to eat dinner, but she soon started to miss that strange feeling. Katsuki dicided that she would do it again after she ate.
Instead of doing it in her room, katsuki need to take a shower so she took her phone and recorded herself while sitting on the toilet lid. She took her pants and underwear off and her shirt and bra. It made her feel uncomfortable but she delt with it as she started to record with her phone on the floor, prompt on a thing of toilet paper.
As she researched earlier, katsuki learned that some people put there fingers inside there vaginas and pump in and out, so katsuki did just that. She took her fingers and put them inside her naked body as she pushed her fingers up. She kept her other hand and fingers on her clit as she rubbed them both. She already felt that welcoming feeling as she just let it slip by, her pussy spasming as she closed her eyes and knit her brows.
She panted for a while before she stopped the recording and got in the shower. Katsuki wasn't recording but she dicided to do it one more time while she stood in the shower, massaging her breasts as she came. She soon washed her hair and got out.
When she put her clothing back on, katsuki put her phone in her pocket as she walked down the stairs.
"Brat, I need you to go out to the store." Mitsuki said
"Why can't you do it?" Katsuki said back as she rolled her eyes.
"I was going to, but I have a meeting i can't miss, so I need you to take my grocery list and go to the store. Its on the counter with my wallet. Your fathers already in the car, we love you thanks. See you tonight." Mitsuki then closed the door.
Katsuki was alone which was nice but she knew her mom would have a cow if she didn't do it. But before that, katsuki sate down on the living room couch and put her phone on the table on a candle as she laid back and put her hand down her pants and her other hand up her shirt. She wanted this one to be quick so she started to rub super fast as she tweeked at her nipples. She threw her haed back as she spasmed in her pants. She immediately got up and stopped recording.
Katsuki then grabbed her moms wallet and the list as she put her shoes on and walked out the door. She took her keys from her pocket and locked the door as she walked to the store. The list was small so katsuki didn't have to grab a cart and just got a basket as she walked inside. She looked at her moms list which was short but, katsuki walked to the bathroom first as she went inside.
Katsuki stepped into a stall as she lowered her pants and panties and hit record as she started to rub at her clit that was puffy from the constant touch. She sped up her hand as someone left. She then put it in her pussy and started to pump her fingers. She moaned as she came, her fingers still inside her puffy pussy. She hit the stop button on her phone and pulled up her pants.
The store wasn't very full on Friday nights for some reason, so it made it easy for her to get her stuff and go.
As katsuki walked home with the grocery bag over her shoulder, she stopped at a store. It said they had a sale, so katsuki wanted to see what the store was and what they sold.
It was a pretty big place as she walked in, but a guy at the front asked for her ID, which katsuki didn't have with her, but her mom and her looked so much a like that katsuki showed off her mothers. The guy said 'okay you may browse' as katsuki walked more in.
The stuff inside looked weird as she walked around. They kind of looked like penises...oh. so that was when katsuki figured out she was in a sex shop. She blushed a little but, she knew what she needed to do. In her research she learned that some woman use vibrators which made masturbating feel ten times better.
So as katsuki looked around, she got a call from her mom. Mitsuki told her that for some reason, izuku and inko where coming for dinner tomorrow, which katsuki just hung up. That just ment katsuki needed to do more as fast she could. So, she grabbed an eleven inch dildo and a high maximum vibrator and bought them with her moms money. She used her credit card at the store so she still had some cash which made it easier for her mom to not notice.
Katsuki bought her items and left to walk home. She was still pretty far away as she sate on a bench with no one around. So, she grabbed her new vibrator and put one of the bits in her pussy and the other part just kind of rested on her clit. She pushed a button on it and it started. Katsuki moaned almost immediately. It was already alot but she pressed it about two more times and put it to high speed as she shakily got out her phone and hit record.
She put her hand in between her legs and shivered as it became to much. Something ended up coming out of her urethra. She thought she pissed herself, but it felt to good to be that.
Katsuki kept walking home with the vibrator on low as she went.
When she got home, katsuki went up stairs after she put stuff away. She then sate on her floor and grabbed the dildo she bought and stuck it to the floor. She grabbed her phone and put herself on the toy and hit record. It was very slim so she sank down on it pretty fast.
Her pussy had been ready for this for about three hours. She started to bounce while on her knees and was already moaning after a minute. She then felt that weird feeling from earlier as she squirt so hard that it reached her phone. She cringed as she whiped it off with her jacket sleeve.
For some odd reason she apologized but she shouldn't have as it was only deku who would see this.
After she cleaned off her phone, she came about three more times before she fell backwards a panting mess. She should have hit the stop button but who cares, deku will just have to see her pussy throb for about five minutes.
At this point, she had cum about ten times.
Before her parents got home, she had about two times on the dildo again, three on The vibrator, and about five on her fingers alone. Around twenty starting from four to midnight.
Katsuki had past out not to long after she fingered herself one more time.
The next morning, katsuki dicided she would put her videos on her computer and edit them. It was about a three hour video when she cut out everything but her orgasms. But uncut was around seven hours long.
It was finally dinner time when she finally finished editing the video. She was kind of excited for deku to watch the video. Not because she wanted him to watch her but because she wanted to prove him fucking wrong.
Izuku and inko had came over at about three, but dinner wouldn't be ready for a while since mitsuki seamed to always work hard when they came by.
So while she worked and inko helped, izuku just kind of sate on The couch remembering his conversation with katsuki yesterday and was kind of nervous. But katsuki walked down the stairs and snapped her fingers "deku."
"Oh, yes."
"Get the fuck up here." Katsuki whispered. She was excited to prove the bastard wrong.
So she walked back to her room as izuku walked behind her. When they where both inside, katsuki closed and locked her door.
"So, about yesterday."
"I'm sorry kacchan, i-i didn't know what i was saying."
"Thats not it deku. I'm not angry, I just wanted to prove you wrong, and I did. I hope you know that."
"Wait you..."
"Yup. Woman can do it you idiot. Alot sometimes too."
"You-you mean you..." izuku studdered while blushing.
"Yup, I. Can. Masturbate. And to really prove you wrong, I'm gonna show you." Katsuki said with a smirk on her face. "Sit back and relax. I'm gonna go sit and watch t.v. while you watch. You're gonna be here a while."
"Why"
"Because, its three hours. Have fun." Katsuki then left izuku to watch the edited version. She clicked play then left the room.
Katsuki sate at the couch when inko walked up to her "hi katsuki, how have you been."
"I've been okay."
"Wheres izuku."
"Oh, he's a little busy." Katsuki said with a smirk. She knew what deku was doing and it made her happy to know that he was wrong.
I mean, he was definitely going to jerk off to her, but, that's not the fucking point.
