Big Sister Sayo's Cheering Up her Bunny Brother!

It has been four days since the UA entrance exam and Izuku taking part in the practical exam though he only got ten points and couldn't get more when the exam ended, Izuku felt like he had failed everything he worked hard for including the effort his family and All Might helped him through the training.

"(After everything I did, it wasn't enough.)" Izuku thought sad as he is walking home from school.

"Hey, Izuku!" Sayo called out, waving at him while waiting in front of their house.

"Oh, Sayo, you're home now?" Izuku surprised to see his big sister here.

"What? Are you not happy to see your big sister today, and I wanted to spend the day with you?" Sayo played like her feeling is hurt.

"Uh, wait, I didn't mean anything like that! I was just surprised since you usually work at the hospital with mom by now." Izuku clarified.

"I know silly, I was just messing with you." Sayo grinned with her tongue sticking out a bit.

"I have a day off today and figured I use it see how my future hero little brother is doing." Sayo explained.

"Well, I'm doing okay… for the most part." Izuku sighed at the last part.

"Are you still bump out about the practical exam?" Sayo asked.

"Yeah, I feel like I really let you all down after helping me get this far." Izuku said.

"Hey, come on, you don't know that for sure since the result letter hadn't come in, yet which should be a few days from now." Sayo pointed out.

"Besides, you remember what mom said when you came home?" Sayo asked.

"Yeah, she said the exam have things that they don't tell the examines until they get the result letter though I still don't know what that means." Izuku recalled those words and look at his big sister.

"Sorry, little bro, but I promise mom I wouldn't tell even though I took the exam myself back when I was your age." Sayo mentioned.

"Right, guess the answer will be in the result letter I'll get soon." Izuku said as he can wait for that.

"That's the spirit. Now let's go inside and play some video games, I've been dying to play this new game I got last week with you!" Sayo wrapped one arm around Izuku and drags him to the house.

"Uh, okay, I don't have homework today anyway." Izuku informed.

The young Midoriya siblings came inside the house and play the fighting video game Sayo mentioned as they are having fun together, which is what Sayo is hoping for to cheer up her younger brother though feel kind of bad to not tell him about the hidden purpose of the UA practical exam. But she figures that seeing his reaction when the result letter comes in would be worth the trouble and know that everything Izuku worked hard for will be rewarded, and then she started thinking about what kind of reward she should give to her little brother.

"Looks like I got you now, Sayo!" Izuku said.

"Huh?" Sayo snapped out of her thoughts and quickly got back in the game.

The two battle each other until the match ended when both of the characters they were playing as were taken out at the same time, thus the round ended in a tie.

"Oh man, that was fun. Right, Izuku?" Sayo asked.

"Yeah, it sure has been a while since I played any video games with you. Can't image why I stop playing with you." Izuku chuckled.

"Probably because of all the studying and training you've been going through for the past ten months, but I didn't mind the wait if it means I can see you happy." Sayo stated.

"Thanks, I'm glad to have you always being there to cheer me up whenever I'm down." Izuku smiled.

"Always little brother, always." Sayo nodded and pulled Izuku into a hug and he return the embrace.

Then the mood started to kick in as they look at each other in the eyes for a few moments and then leaning their faces closer with their lips outward a little as they are just a few inches closer.

Sayo's cellphone went off stopping the two from advancing their approach as she reaches her right arm to get it while Izuku quickly turn his head around upon realizing what was about to happen and his face turning red. The blue hair older sister see the caller ID is their mom and press the green phone symbol on the screen of her phone.

"Hey mom, what's up?" Sayo asked.

"Hey Sayo, just calling to check on how are you and Izuku are doing." Yuko said.

"We're doing great, playing a video game together and enjoying each other's company too. You could say we're getting closer." Sayo reported with a slight teasing tone.

"That's good to hear, I also have to inform you guys that I'll be coming home really late tonight." Yuko informed.

"If that's the case then it must be a patient with a serious bad condition." Sayo figured as something like that happens at the hospital they work at.

"Indeed, four Pro Heroes were fighting this one villain that has a Quirk to control other people's blood. They were able to stop the villain, but they suffered heavy injuries on themselves, you two will have to do dinner without me." Yuko explained the situation.

"Not to worry, mom, we'll save you some dinner and give my hope for those Pro Heroes." Sayo said.

"I will, bye." Yuko said before hanging up.

"Bye mom." Sayo said as she hung up.

"Mom got held back from work?" Izuku guessed.

"Yeah, said she won't be back for a while, so we'll be saving her some dinner." Sayo said.

"I see, must be nice working at the hospital to help all those people get better and seeing those smiling faces." Izuku imagined.

"It can be like that, but same can be said about the Pro heroes out there fighting the villains and seeing the people smile knowing they are safe. That's good." Sayo believed.

"Yeah, which is one of the main reasons why I wanted to be a hero in the first place." Izuku smiled.

"I know. How about we get dinner started." Sayo suggested.

"Sure." Izuku said as he got up and walked to the kitchen.

"(I can tell he's still a little bothered about the UA exam, maybe there's something else I can do to cheer him up.)" Sayo thought tried to think of a plan.

As she thinks, a memory pop into her head and it was the memory of her kissing Izuku on the lips when they were in the bathroom together before the UA entrance exam.

"Oh, I think I know how." Sayo smirked while mentally apologizing to her mom.

(Later)

Izuku is in his room sitting on his bed and lifting a dumbbell for a little late workout to keep his body in good shape to get ready for the result letter from UA, but he gets worried again that he may not get in. He knows he did well in the written test thanks to keeping up with his studies, and some help from his mom, but he thought back on the practical exam remember he only got ten points from beating this villain robots knowing he needed more than that. But his mind went to the memories of saving that orange hair girl and Ochaco, he felt proud of saving them.

"Hey Izuku, mind if I come in?" Sayo asked knocking on her door a bit.

"Sure, you can come in-AH?!" Izuku gasped as his face turns red when he saw Sayo walking in nothing but her very revealing underwear and bra.

"S-S-Sayo, what are doing wearing that?" Izuku asked.

"I just thought of a way to cheer up my green bunny brother since the entrance is still bothering you." Sayo answered as she sat down next to him.

"Huh, and what way is th-that?" Izuku asked stutter.

"I was thinking of doing something more than that kiss we did." Sayo grinned making her brother blushes harder.

"S-Sayo, I'm f-fine. There is no need to" Izuku's sentence was cut off when Sayo kissed him on the lips and hug his body, pressing her breasts against his chest.

Unlike the last kiss they did, this one is longer as Izuku slowly sinks in and wrap his arms around her body and his soul feels like a big firework explosion going off, and both his hands went down from the back to her butt giving the bottom cheeks a firm squeeze which made her moan in the kiss.

"Sorry, I wasn't, I mean I…" Izuku panicked as he didn't know what to do at this point.

"Don't worry, it's your first time. We'll take it slowly, together." Sayo said in a sexy and calm tone. She reach for the back to unclip her bra, throwing it down exposing them to her brother's eyes, and took Izuku's hand and place them onto her breasts as he gasps.

"Try giving them a good squeeze, and don't worry about being a little rough. You can do whatever you want with them." Sayo whispered in Izuku's ear.

Izuku gulp that he is touch a girl's breasts, much less his own sister's, for the first time in his life and clutch his hands a little to feel the fleshy orbs' softness in his palms and squeeze them a little harder making Sayo moan as she smiles. He continues squeezing them and start moving them around, he felt something poking at his hand and soon saw the nipples getting hard meaning Sayo is feeling arouse from this as is eyes became fixated on them, he moves a finger on one nipple making her yelp a little. His inner male instinct made him lean forward and lick the nipple with his tongue getting the taste of her big sister, then he starts sucking on it with his mouth making Sayo moan loud a little as she hugs him into her breasts more and he suck on the other nipple.

"Oh my, you really love my breasts, do you?" Sayo asked moaning for a moment before she push him off.

"I think it's time to let your little friend out." Sayo rubbed her finger on the harden part of his pants.

Sayo pushes Izuku to lay down on his bed and pulls his pants off to get a good look at his penis which has harden strong and standing about 11 inches and throbbing.

"When I first saw this, I couldn't stop thinking about how amazing it looks coming from the strong man I know." Sayo complimented as she pokes the tip.

"This feels embarrassing." Izuku said blusning.

"Don't worry, this is going to feel great for you in no time." Sayo said as she starts stroking the cock with her hands.

Izuku let out a little moaning sound which was cute to Sayo as she is going to give her brother his first blowjob, she can feel the penis warmth in her hands and stick out her tongue to lick the length making this feel good for Izuku as he moans a little louder. She swirls her tongue around on the tip for a little while before she sucks on in and engulf the cock into her mouth, she bobs her head a little slow to get the pleasurable feeling through to Izuku.

"Oh wow, your mouth feels so go!" Izuku moaned.

"(That's right, Izuku. Get turn on more from your big sister!)" Sayo thought moaned.

She sucks the cock more as she can feel Izuku's body twitching from the pleasure of the blowjob and felt the meaty pole of Izuku Jr getting harder in her mouth.

"Oh, it looks like you're about to cum. Let me make this special." Sayo sandwiched Izuku's penis into her large boobs rubbing them together.

"S-Sayo, that's too much! I'll… I'm gonna… AAH!" Izuku screamed as his cock released a big load of white seum like a water fountain as some splat on Sayo's face and breasts.

"Wow, I wasn't expecting you to release so much at once." Sayo surprised and licks the cum finding Izuku's taste to be good.

"Yeah, it was great. Thanks for giving me this new experience." Izuku thanked.

"You're making it sound like we're done here." Sayo smirked.

"W-We're not?" Izuku shocked.

"Not according to your little friend here." Sayo pointed at Izuku's cock still harden and strong.

"I think it's time we get to main course, little brother." Sayo removed her underwear, tossing it to the floor and positioned herself above the cock.

"W-Wait, are you really sure about this?" Izuku asked, and Sayo press her finger on his lips.

"I wouldn't be doing this if I didn't love so you more than a brother." Sayo answered, and pushes herself down, struggle on the first half until she came all the way down and little blood came out as she screams.

"Are you alright, Sayo!" Izuku asked worry.

"Don't worry, this just means we both have taken each other's virginity." Sayo said.

"Each other's… that means you were…" Izuku gasped of realization and Sayo leans down to kiss him on the lips again.

"Now let make this a truly sister and brother moment." Sayo declared as she starts moving her hips down and up, a little fast of how exciting this is for her.

Feeling his sister's pussy tightly wrap around his cock feels good to Izuku as he moans from the intense pleasure he is having; he grabs onto her hips to pull her down harder and thrusting his cock deeper inside of her as she moans crazy of the experience.

"(Yes, this is it! This is what I've always wanted from him!)" Sayo thought moaned smiling.

Izuku looks up seeing the smiling face on Sayo as she enjoys having her pussy being fucked by him and his body is enjoying this too with the sex feeling goes into his mind, his eyes wander to the sight of her breasts bouncing freely and latch his hands onto them for a stronger groping.

"Ah! Izuku! This feels so good, I love you! I love you and your big cock!" Sayo confessed before she leans down kissing him again as he kissed her back.

Her pussy gets tighter from the continue fucking as Izuku's cock keeps ramming through the tightness and the jolts of pleasure coursing through Sayo's body as she can feel her womb getting hit as it desires this boy's cock.

Sayo has always dreamt of doing this with Izuku for a long time, probably a couple of years or so when she saw how much he is growing and after the ten months of training made him even manly than ever as she couldn't hold herself back anymore.

"Sayo, I… I think I'm about to cum again!" Izuku warned.

"Oh, yes, go on and let it out in me!" Sayo moaned.

"What? But if I do that then you'll get pregnant!" Izuku gasped.

"Don't worry about that, I took a pill before coming to your room. You can let out as much as you want!" Sayo informed while moaning.

"S-Sayo!" Izuku lifted himself up and hug his big sister.

"Yes, yes, give me all of your cum now!" Sayo moaned.

A moment later, Sayo slammed herself down against Izuku's flesh and his penis started to release more white cum inside her pussy as she screams of joy.

"That was amazing, my green bunny." Sayo said as she and Izuku are lying down together.

"Yeah, it was though I was really scared about cumming inside of you." Izuku panted a little.

"Come on, I've been a nurse for years. I know how to be prepared for these sorts of things." Sayo stated.

"So, what we did… does that mean we're a couple now or something?" Izuku asked.

"I believe we are, even though we're brother and sister, and it's already too late to turn back now." Sayo answered, snuggling her cheek on his.

"It just feels so weird." Izuku sighed.

"Well, I'm sure you'll get use to it. Speaking of which, I think you should do the same to mom." Sayo suggested.

"Okay, well-Wait, what?!" Izuku asked shock and Sayo giggles.
