hinagikus failed courage tests

katsura hinagiku, after being shamed on her fear of heights. caused her to lose an event race. eager to overcome her fear she returns to the bridge alone,wetting herself, as she fails to cross it. feelings and her pride fight to overcome this fear even if it means wearing diapers.

After the incident with Hayate, Hinagiku decides to confront her fears head-on, and goes off to confront her fear of heights by going up a tall building by herself. While she does manage to make it across the bridge, she eventually loses her nerve and starts panicking, wetting herself. so even if she crossed the bridge with her eyes closed. she was ashamed that she dident notice her accident. feeling she failed, but inspite this an excitement she dident understand or admit welled up in her. as if she had found something new. something that made her feel excited and happy. on her walk home once her spats and leggings was dried.taking an alternate route to avoid being seen. she saw them, Adult diapers. blushing furiously as she passed the display of the undergarmets. she felt embarrassed and shamefully happy she thought as she walked away.Hinagiku is a high school student attending the Hakuo Academy, shes too big for diapers. the embarrsment of such a thing made her bite her lip. trying to ignore how it made her feel. but she wanted to cross the bridge without wetting herself. and her clothes was soaked. she hated it. but she found herself going into the store, and buying a very infantile and thick set of adult diapers. and despite the shame she knew she would feel later. she changed into a diaper. wearing it under her school uniform. as she went out to confront her fear of heights. she crossed the bridge holding onto the railing tightly. as if she were a child again. and as she did her skirt was lifted up slightly by the wind. exposing her diaper underneath.but she was so scared she dident notice, having her first accident in the diaper. the warm feelings flooding her tender regions. a new erotic feeling was blooming along side her fear in that moment. as if she were experiencing both at once.and suddenly she noticed it. the wetness between her legs. and how her diaper rubbed her pussy with ever step.the weight of her shame pressing upon her womanhood, the humiliation of it all.she looked down to see she was peeing in her diaper. and not noticing it. where had her skirt gone!

"My...my pants!"

She quickly pulled it back down, but when she tried to cover herself, she realized that her skirt was now wet right through her panties. The embarrassment of that realization was too much for her, and she started crying. falling to the center of the bridge the heavy padding rubbing her most intimate regions.

"I'm gonna die...in a diaper , everyones gonna rember hinagiku as the girl who died on a bridge in a diaper."

she couldn't believe it. she was humiliated and ashamed. but she couldnt stop herself. the shame she felt was making her want it more. wanting to get it over with before anyone saw her. she took a deep breath and closed her eyes, trying to ignore the burning sensation in her crotch. and opened her legs wide. moving forward she allowed herself to fall forwards, her hands clutching at the railing as she crawled like a baby. "but i am doing it right?" hinagiku thought, concentrating on the pleasurable sensation to help forget her fears.

as she moved her fingers lightly against her pussy. wetting her diaper she felt the wetness from inside her vagina soak through the diaper and leak down her thighs. suddenly the burning sensation in her cunt grew stronger, her body tensing up as an orgasm began to build. she moaned loudly, grunting as she came. her face turning red as she climaxed, squeezing her eyes shut tight and biting her lip hard. falling exausted on the other side of the bridge tingling with pleasure. she rolled over onto her back, lying there panting as she tried to regain some composure.

"i cant believe I just did that...why did I do that? why did i let myself go like that?" hinagiku wondered aloud as she lay there. her thoughts running wild as she got snuck home.

The next day at school, Hinagiku finds herself avoiding many of her friends. She's afraid that they will find out about what happened on the bridge yesterday. her thoughts drifting towards going to her lookout tower to look down at the school. but she felt insecure about doing so. at least not without another diaper on. She walks around the school in a daze, trying to figure out if she can put one of her spare diapers in her bag or hide it somewhere. Finally she settles on putting it in her locker and locking it. Taking it out in the morning to change herself before class and leaving it in her locker for the rest of the day.

"I hope noone sees me with my diaper bulging out of my skirt..."

As she opens her locker to grab her gym shorts, she notices that they wont fit over her thick pillow like baby diaper. she now had to choose to either go around school without the security of the spats or the security of her diaper.

"This is a bad idea...but I just want to be able to look at the school view without holding his hand." and with that she choose to put on the diaper under her uniform.

having it bulge out of her skirt as she walked to the toilet. only to take it off and leave it in her locker after using it.

the feeling of the thick padded diaper against her sensitive pussy made her feel embarrassed. but she needed it badly.

"Why did I have to wear a diaper? Why do I need this?"

She looks at herself in the bathroom mirror, feeling very self-conscious. But she pushes those thoughts aside as she gets dressed. And as she walks to the lookout, she feels strangely giddy.

"I still don't know what the point of wearing diapers is...but I gotta say...it feels good."

Her first time on the lookout, Hinagiku's heart beats faster as she looks down at the school, as if on cue the childish excitement of seeing the school. and the erotic sensation of her accident all kick in.

"How long has it been since I've been here?"

She looks around. It seems so strange to see the school this way, as if she were looking down at it from above.

"It's been so long."

She takes a deep breath. Inhaling deeply, she steps out onto the top of the lookout. She feels a rush of excitement as she looks down at the school below. Her heart beating fast as she slowly moves forward until she reaches the edge. The sensation of the thick padding rubbing against her pussy and clit makes her gasp in surprise, causing her let out a soft girlish moan. one she dident know she had. and then before she knew it she was standing on the edge with her legs spread apart. letting her skirt lift up a bit, her diaper pressing on the bar she clinged to for support.

"I can't believe I'm doing this...this is so embarrassing..." she says to herself, her hips bucking as she trembles. letting another sharp moan leave her lips.

"Oh...ohhhh...I'm gonna...i'm gonna cum... I can't hold it anymore!" she cried out, her hips jerking as she came. a wave of pleasure washing over her as she squeezed her eyes shut tight and bit her lip hard.

"Ahhh...ahhhh...ahhhhhh..."

Afterward, Hinagiku stands there panting, her diaper damp with her own cum and pee. She looks around, feeling embarrassed at the mess she made. She wipes herself off, trying to clean herself as best she can.

"Ugh...I can't believe I did that. but the view, was nice right."

She sighs heavily. telling herself the half truth, not wanting to admit to even herself the unexpected climax she had with a diaper. With that she turns to the school and begins walking home, feeling oddly aroused as she thinks about what might have happened if anyone had seen.

"Maybe I should put on a diaper whenever I go out and use the lookout."

Her thoughts wander as she walks home.

"If I wore diapers all the time maybe I'd be able to act less like a little girl, and enjoy heights like any normal girl."

But she doesn't really mean that. She just wants to feel like a real girl, one who someone can take care of her the way she cares for others.

A few days pass. Hinagiku is more relaxed around her friends, even though she has yet to tell them about her accident, or wearing diapers. She continues to wear her diapers around the house, trying to convince herself that she just needs them for comfort. "It's not like I actually like the way they feel or anything," she tells herself, thinking about how she feels embarrassed while wearing them. But she knows that she can't tell them the truth. They would think she was crazy.

"They'll probably laugh at me if I told them I wear diapers."

And besides, her fear of heights hasn't abated. in fact it only got worse. She avoids going out on the lookout finding just looking at it she was wetting her diaper from her office chair.

"What's wrong with me? This isn't normal!" she said breathing heavy clutching the swelling padding.

"I need to stop...but I...can't...I have to go on it again...I have to face my fear...I have to try once more." she told herself attempting to ignore how aroused she was feeling, or how she was getting a sexual high off of feeling scared and ashamed.

Once again she makes her way to the lookout, her hand still on her diaper. As she approached the door she felt her heart begin to pound as she gripped the doorknob. She opened it and stepped out onto the top of the lookout. looking down at the school body from above.

"This is stupid...I'm just feeling horny..." she thought, pulling her skirt up slightly to expose her diaper. "Just because I'm wearing a diaper does that mean I have to show everyone?" she asked herself, moving forward as she could feel herself becoming excited.

"I don't really have to be naked right?" she thought, crossing the threshold and letting her skirt fall back down again.

Having her skirt rise up a bit made her realize that she was exposing quite a lot of leg for a girl her age. She felt her cheeks grow hot as she looked down at herself, knowing full well the people in the school were watching her.

"What am I doing? This is dumb. I'm going to get caught out here..."

Suddenly she hears a voice call out from behind her: "Hey! What are you doing?!"

Hinagiku turned around to see that it was one of her friends.

"What?" she said defensively. "I just wanted to look down at the school."

She looked down at her diaper, which was bulging out of her skirt, making it obvious that she was wearing one. Hinagiku felt her cheeks growing warm. hayate just looked at her and closed the door.

"Come on Hayate...tell me what's going on." she said, annoyed.

"are you ok hinagiku your face is red" hinagiku blushed a deep scarlet,saying back "Its just stuffy in here thats all! so I-i wanted some fresh air." her thighs rubbing together. feeling more aroused at seeing hayate while in such an weakened state.Hayate looked at her and smiled. hinagikus letting out a soft pant as she felt more warmness flooding her diaper. helpless and aware of her accident as the boy she liked was looking at her, all while she was peeing the diaper under her uniform.Hinagiku's eyes widened as she felt another wave of embarrassment wash over her.

"I can't believe I did that...again!"

"Why am I doing this? This is so embarrassing..."

Hinagiku sits there, feeling both embarrassed and aroused by the situation. it was all she could do to not start playing with herself.

"I can't believe I'm acting like this. Why am I letting myself go like this?"

She looks away from Hayate, feeling guilty.

"I should be able to control myself. This isn't like me."

But she couldn't help it. The embarrassment and shame of being discovered, coupled with the arousal she felt from wearing a diaper, made her body betray her. She felt her thighs getting moister, and the warmth between her legs growing deeper and stronger.

"I just want to cum..."

She looks at Hayate, hoping he didn't notice her condition. She tries to cover up, but her hands shake as she fumbles with her skirt. hayate worried only comes closer to her. she began to cry fearing shed get caught.

"I.I'm so embarassed...please don't tell anyone..."

she begs him softly, her hands shaking as she clutches her skirt. hayate looks at her confused. touching her forhead "oh are you running a fever Hina? let me go get you some medicine right away" the kindness making her wail softly. orgasming right in front of him eye to eye.

"I'm sorry...soo muhhh..."

her orgasm washing over her as she lets out a faint girly moan into his ear. she quickly covers up, her hands trembling as she tries to hide the wet spot forming on her skirt. her diaper was leaking. the sensation of the warm liquid soaking through her panties only making her feel even more ashamed. hayate worried left hinagiku alone .

"I'm so stupid..." she said to herself, throwing off her uniform to get changed. naked in her diaper. she fondles the padding, looking at her reflection. her face was flushed, her cheeks red.

"I can't believe I did that...again."

She feels a flush of excitement as she wonders if she might have another accident. Her thoughts turn to the other times she's worn a diaper. In particular, the last time she was wearing one when Hayate found her.

"I wonder if he saw me...if he noticed my diaper. would he treat me like a big baby the way he does for nagi."

She imagines him carrying her around and feeding her a bottle. And she feels warm and wet between her legs. rubbing the diaper with her hand. craving his affection.

"I can't believe I'm acting like this...why am I letting myself go like this?" she humps the diaper to her hand. watching her play with herself. moaning and cooing needily. feeling warm all over and her thighs rubbing eachother as she spreads her legs apart.

"I'm just acting like a baby...like a little girl...but look at yourself hina this is the real you a flat breasted big baby, only pretending to be a big girl"

her body burning with desire. desperately wanting to cum. looking at her adult perception melt away sinking into erotic pleasure. her hips bucking as she rubs herself against the padded padding, her diaper now soaked with her own cum.rubbing on her tender needy pussy. her mind flooding with pleasure. she feels her arms shaking as she gets closer to cumming.

"Oh god...oh...ohhhh...ahhhh...ahhhhhhhh..."

Hinagiku cries out, her hips bucking as she begins to come.

"Ahhhh...ahhh...ahhhhhh..."

The warm liquid gushes forth, filling her leaking diaper.

Her hips bucking wildly as she cums. her breasts bouncing as she rides out her climax.

"Ahhh...ahhhhh...ahhhh..."

Afterward, Hinagiku lies there panting, feeling exhausted. She looks down at her messy diaper. It was soiled from her release, and she had to change herself right away. but her body felt heavy. the carpet was wet. and she knew she had to lie there for a while before she could stand up. but he could return any moment. crawling weakly and desperatly to make it like it never happened.

Eventually she crawls to the edge of the room. The carpet was soaked. Her head aches from lying down for too long. She looks at herself in the mirror, and realizes that she's covered in a thick layer of sweat.

"I can't believe I did that...again."

She changes herself, wiping herself dry and changing her diaper. Then she crawls to get her spare uniform on.

"I hope he doesn't find out. I don't know what I'd do if he sees me like that..."

She makes her way back to her desk, hoping no one else will see her, crawling like a baby

"I can't believe I'm acting like this..." she slumps on her desk weakly.

Then Hayate returns. Hinagiku looks up at him, wondering what he's going to say, what he's going to do.

"Hina...you're not well?" Hayate asks.

She nods, feeling embarrassed.

"What cant a girl just be sick?" hina asked filled with shame. defensive for the soiled items she had hidden.

"Hina..." Hayate said hugging her. she blushes and looks away. "You don't have to be embarrassed about it" Hayate said giving her a kiss on the forehead.

Hinagiku blushes deeply too weak to resist the advances.

"oh i'm so sorry i havnt been there for you hina...i should have known something was wrong with you"

Hinagiku blushes hiding her smile.

"Hayate..." she whispered. biting her lip hoping the moment doesnt end.

"there's nothing to be ashamed of..." hayate said putting a damp towel on her head.

Hinagiku contemplates teasing him, wanting to see how far hed go to pamper her. to comfort her. to give her what she needs.Hinagiku blushes and smiles coyly , "so hayate do you just like have a thing for helpless girls?"

Hayate blushes "no no im just trying to help" he said taking out a glass jar.

Hinagiku takes the jar from him, sniffing at it curiously.

"what is it?" she asks.

"its an herbal remedy to help with fevers"

Hinagiku opens the lid and smells the contents.

"its kind of sweet..." she says, tasting it.

Hinagiku's eyes widen as she tastes her new medicine. It tasted sweet and fruity.

"it's good Hayate...thank you..."

"you're welcome..." he said kissing her forehead.

Hinagiku blushes, feeling a surge of arousal run through her body. she was really pamping her.

"I'm glad you like it" he said smiling.

Hinagiku giggled slightly, feeling her diaper beginning to swell.

"It's kinda hard to concentrate..." she says.

Hinagiku feels herself getting wetter.

"is something wrong hina?" hayate asked concerned.

"N-No." she said, blushing.wondering how she could be wet already. losing the composure to tease him more. goosebumps forming on her skin.Hinagiku blushes, feeling a rush of heat spread through her body.

"Hina...are you sure you're alright?"

Hinagiku looks up at him, suddenly feeling as if he could see her diaper. surely hes not noticing.

"I'm fine..." she whispers weakly, exausted from her climax, and emotions.

"I'll be better after I drink some water..." hinagiku says. "but your bottle is empty let get you some more." hayate replied grabbing her sports bottle to refill it. he dangeriously closed to where her used diaper and soiled uniform was hidden. Hinagiku looks away and blushes. "please dont notice" she thinks to herself.

"hey hayate?"

"yeah?"

"do you think im a big baby?" hinagiku whispers, curious to hear what he would say.

Hayate smiles "of course not! everyone gets sick hina here" he offers the bottle but she fumbles it as it falls. she looks up at him shyly.

"here..." he said picking it up again. putting it to her lip himself"drink up, hina."

Hinagiku drinks eagerly

"your thirsty huh?" he says looking down at her.

Hinagiku swallows the remaining liquid, blushing furiously.trying to enjoy the moment,feeling lightheaded.Hinagiku closes her eyes, feeling a tingle run down her spine as he nurses her with the bottle.Hinagiku blushes, feeling her heart flutter with desire, enjoying the sensation of being cared for.

"Hayate...I..." she starts, but then stops. "can we keep doing this?"

Hinagiku asks him, looking at him with her big brown eyes. Hoping he would agree.

"of course! untill you feel better"Hinagiku smiled happily, eager to continue."mo-more water please" she said with a hint of seduction in her voice.Hayate blushes from her flirting tone."su-sure" he said, refilling her bottle.Hinagiku looks at him, longing for his attention. lost in her thoughts as hayate accidently spilled the water on her, soaking her last uniform."I'm sorry" he said apologetically.Hinagiku blushed, feeling a wave of wetness in her diaper. her damp uniform clinging to her skin. "let get you cleaned up before you get sicker" he said leading hinagiku by the hand.Hinagiku follows, happy to be taken care of. unaware the shape of her diaper was showing from her wet uniform. waddling behind him."I'm sorry about the mess..." he said, cleaning the floor. Hinagiku blushes, feeling embarrassed and turned on at the same time.she was holding hands with hayate! but as hayate looks up the diaper bulge was obvious. hina oblivious to this fact. as hayate was now blushing. "hina is that a diaper"

Wetness filled her diaper, thickening the fabric.

"I want you to take care of me Hayate..." hina said softly.

Hinagiku felt her diaper become even wetter.

"hina!" Hayate said shocked.

Hinagiku blushes."please" she pleaded.

Hinagiku was surprised by how easily she was confessing her feelings. she had never done anything like this before.

"I want you to take care of me Hayate.." she lifts her skirt letting him see the diaper.

Hinagiku blushes, realizing what she had just done. but she couldn't stop herself.

"Hina!"

"Please..." she moaned.

Hinagiku blushes, feeling her diaper growing wetter. peeing herself from fear shed reject him. but caught. she had no other choice.

Hinagiku feels a warmth between her legs, her diaper becoming a sticky mess.

"Hina!"

"Wet yourself?"

"yes..." she said softly.

Hinagiku's heart races.

"I'll take care of you...I promise..."

Hinagiku blushes, feeling his touch on her. she knows that he must have noticed her damp diaper. but instead of making fun of her, or leaving her to herself he was comforting her. it was only turning her on more.

"come on Hayate..."

"don't worry hina...I won't tell anyone"

Hinagiku blushes, feeling his fingers trace her diaper. she shivers at his gentle ministrations, letting him do whatever he wanted.

"I'm not a little girl anymore Hayate...not unless you treat me like one..."

"If it's what you want hina-"

Hinagiku's mind swirls with pleasure.

"I love it when you call me that..."

Hinagiku feels herself getting aroused.

Hinagiku blushes, feeling him look down at her.

"Please...just once...baby me like you baby nagi."

Hinagiku blushes at the words slipping out.

Hinagiku blushes, feeling her diaper grow heavier.

"i-if you want to..." she pleads.

Hinagiku feels herself getting wetter and wetter.

Hinagiku feels her diaper soggy.

Hinagiku blushes, undoing her uniform. her shame and nudity laid bare. wiggling in the pink baby diaper. in front of hayate. feeling the weight of it against her thighs.

Hinagiku blushes,"I-I'm sorry..." she says.

Hinagiku looks up at him, wondering what she had gotten herself into.

"Its ok...it's my fault for not being careful" he said looking down at hina. he gently picks her up and carries her

Hinagiku blushes, feeling his arms around her. she leans in closer. "I want you to take care of me Hayate..." she whispers.

Hinagiku blushes, feeling her diaper slip down.

Her diaper is soaked.

"I-I'm sorry..." hina said looking up at him with puppy dog eyes.

"Your fine..."

Hinagiku blushes, feeling his hand brushing against her diaper.

"Do you need a change?" he asks.

Hinagiku is confused, unsure how she should answer.

"I-I don't know..."

Hinagiku blushes, feeling embarrassed.

Hinagiku feels herself getting wetter.

Hinagiku blushes, feeling his fingers brush against her. She blushes harder, knowing that she shouldn't be getting turned on by this. But she can't help herself.

Hayate smiles ."its ok, i understand"

"You do?" hina gasping shocked.

"yeah..."

Hinagiku blushes, feeling his fingers tracing along her diaper.

"Do you want to stay like this?" he asks, looking down at her.

Hinagiku blushes, feeling her diaper grow heavy.

"I-I don't know..."

"Just for tonight? you can have the next day off from school"

"I...I don't know..."

Hinagiku blushes, feeling her diaper grow wetter.

Hinagiku looks up at him, wondering why he would go out of his way to take care of her.

"I-I..."
