Light of Courage by Imouto Kitten

Chapter 2: Bathtime

As Taichi sits down in the warm water, Hikari sits down between his 
legs, her tiny tush pressing against his crotch. Realizing he forgot to 
grab a washcloth, Taichi decides to pour some of the body wash his 
parents use with Hikari, a special gentle formula designed with a baby's 
sensitive skin in mind, directly into his palms and starts to wash his 
little sister by rubbing his bare hands all over her naked body. As he 
does so, his immature boyhood starts to grow stiff from touching a naked 
girl in such an intimate, yet innocent fashion, but knowing nothing of 
sex, the boy ignores it as he makes sure to wash every nook and cranny 
Hikari has in common with himself.

But the girl isn't as keen to ignore the unintentional effect she's 
having on her big brother, eventually asking, "Is that Onii-chan's 
thingy poking my butt?"

"Yeah, I guess it is." replies Taichi, not thinking much of the 
situation, knowing that getting all stiff like it is at the moment is 
just something his thing does from time-to-time.

"Can I look at it? Papa never lets me get a good look at his when I take 
a bath with Papa." Asks the little girl, curious about how boys and 
girls are different from each other.

Not thinking that their father might have good reason to discourage 
Hikari's innocent curiosity, the boy answers, "Sure, go ahead.

"Yay!" cries the girl, standing up, giving her brother an up close view 
of her cute, little butt as water cascades off her tiny half moons 
before she turns around and drops to all fours, nearly coming nose to 
tip with her brother's boyhood, exclaiming, "It's a lot smaller and 
cuter than Papa's, at least from the glimpses I get of Papa's when Papa 
gives me a bath." Taichi blushes and takes her words as the compliment 
they are meant to be, as ignorant as his sister of the fact that calling 
a boy's thing small is usually an insult. Embarrassed at having a girl 
looking at his privates so closely, he fails to notice Hikari reaching a 
hand for his shaft, only snapping back to reality when she asks, "Can I 
touch it?"

"Uh, sure." replies Taichi mere seconds before his sister's tiny fingers 
wrap around him, the boy letting out a moan of pleasure as Hikari's 
touch sends a jolt of electricity up his spine.

Worried, Hikari asks, "Did that hurt, Onii-chan?"

"No," replies the boy with a pant, "In fact, it felt really good."

Encouraged by this declaration, Hikari starts running her hand up and 
down her brother's length before leaning down even further to rub her 
cheek against it, commenting, "Onii-chan's thingy is so warm and stiff." 
Blushing she asks, "Is it okay if I call Onii-chan's thingy Ototo-chan?"

Finding the idea of his little sister calling her big brother's thing 
'little brother' strikes Taichi as absolutely adorable, so he replies, 
"Sure, go ahead." as he runs his fingers through her short hair.

Hikari gives her brother a smile before doing something that honestly 
surprises her as much as it does him. Perhaps having a warm protrusion 
rubbing against her cheek reawakens a dormant suckling reflex, or some 
unknown instinct tells her it'll make her big brother feel good, but for 
one reason or another, Hikari suddenly opens her mouth and swallows her 
brother's boyhood all the way to his balls and starts sucking like a 
starving infant at her mother's teat. Though not sure why she started, 
the increased volume of her brother's moans and the way he starts to 
massage her scalp only encourage Hikari to continue giving her brother 
his first blowjob, not that either has any idea that that's what she's 
doing, and the little girl is soon bobbing her head enthusiastically 
upon her brother's boyhood.

Taichi can feel something building in his loins, and though he has no 
clue what is happening, he's disappointed all the same when Hikari 
suddenly pulls her mouth from his member, making him whine, "Why...Why 
did you stop?"

"Onii-chan," starts the little girl, "my kitty feels tingly, and it not 
the tingly I get when I gotta potty."

Scratching his head in thought, Taichi eventually comes to the 
conclusion, "Maybe your kitty is trying to tell you it wants to be 
played with like you've been playing with my thingy."

"That must be it!" Cries the little girl before turning around, all but 
thrusting her girlhood in her brother's face as she declares, "Please 
Onii-chan, play with my kitty!"

Today wasn't the first time Taichi has seen his sister naked, and he has 
seen his mother naked on the many occasions he bathed with her prior to 
becoming old enough to take baths by himself, but he's never seen a 
girl's privates so closely before, much less been given permission to 
actually touch a girl there, so the boy is both excited and nervous as 
he reaches his hands out and uses his thumbs to part Hikari's folds. As 
he does so, the scent of little girl sends his head spinning and it 
takes a force of will to focus enough to see the two tiny holes and the 
equally tiny nub that his sister's netherlips had been concealing.

Probing each in turn, the smaller hole, which he would much later learn 
to be the opening to her urethra, proves too small for any of his finger 
tips to enter, but the slightly larger hole proves receptive to being 
filled with his finger, Hikari crying out, "Feels good!" as she lets out 
a low moaning and shivers from her brother's touch, only to let out a 
loud gasp as his thumb grazes her tiny clit.

Hearing his sister's cry, it's Taichi's turn to ask, "Did I hurt you?"

"No, Onii-chan," replies Hikari, trembling in pleasure, "It felt super 
good!"

Taichi is relieved that she's enjoying herself, but also worried that 
she'll collapse into the bathwater with how she's trembling when he 
remembers how much better it felt when she was sucking his thing as 
opposed to just touching it. Turning her around, Taichi lifts her up so 
he can throw her legs over his shoulders and buries his tongue in her 
folds as he maintains a firm grip around her waist. Enjoying her taste 
and the moans this draws from her throat, he doesn't even mind as Hikari 
wraps her legs around his neck just short of tight enough to strangle 
and fists her tiny hands in his hair.

"Onii-chan," cries Hikari in ecstasy, "Onii-chan, my tummy feels all 
tight." Neither knows what is happening, but the little girl is nearing 
her very first orgasm, and her brother is enjoying eating her out too 
much to stop, so it isn't long before she's crying out, 
"Oniiiiiii-chaaaaaaan!" as her entire body convulses with her very first 
climax.

Sensing that she needs a break, Taichi lowers Hikari into his lap, 
crosses his legs under her butt as she pants against his bare chest as 
he comments, "You seem to really enjoy that."

"Wow, Onii-chan!" is all she can say in reply for several minutes.

Realizing that his thingy is still stiff and that his sister's girlhood 
is practically rubbing against his boyhood, Taichi gets an idea, 
"Hikari, you know that hole in your kitty I stuck my finger in?"

"Yeah, Onii-chan?"

"Do you think my thingy would fit in there?"

Tilting her head, but getting what her brother is probably thinking, she 
replies, "I don't know, but I bet it would feel great for both of us." 
Without any hesitation, Hikari lifts her butt from her brother's lap, 
and lining up his tip with her opening, drops back down. As her weight 
forces her brother's member into her immature cunny, tearing through her 
hymen in the process, Hikari lets out a scream of pain and clutches 
Taichi's shoulders as tight as she can.

Worried that he's seriously injured his little sister, Taichi makes to 
pull her off of his cock, but she shakes her head, chanting "No pull 
out, no pull out, no pull out! Hurts more if pull out!" Leaving the boy 
to watch as his sister grits her teeth and shuts her eyes against tears 
as she tries to endure her shredded virginity.

After what seems like an eternity, Hikari relaxes against her brother's 
chest once more, the pain subsiding, but when she tries to pull off of 
him, her nerves light up once more, but this time in pleasure instead of 
pain. Instead of pulling off completely, she sinks back down, and befor 
Taichi realizes it, his sister has made a 180 from when she first 
impaled herself on his member, bouncing in his lap with abandon, and 
considering it feels even better than when she was sucking him, the boy 
couldn't be happier.

Grabbing her tiny half-moons, Taichi starts to help Hikari move up and 
down on his shaft as she wraps her legs around his waist and her arms 
around his neck as well as she can. Both siblings can feel the 
sensations they recall from when the other was using their mouth on 
their privates building once more, and this time, Taichi isn't cut off 
just shy of climax as he experiences his own first orgasm. Though too 
young by several years to produce sperm, that doesn't stop Taichi's 
member from twitching violently in Hikari's depths, bringing her to 
climax once more, and though she's too young by even more to have viable 
eggs, that doesn't stop her pussy from trying to milk him for all he's 
worth.

The two sit panting in the bathtub for some time before hearing the 
buzzer from the dryer and Taichi suggests, "We should probably get out 
before Mama and Papa get home."

"Sure thing, Onii-chan." replies Hikari, finally pulling herself off her 
brother's now wilted boyhood.

After drying himself and his sister, Taichi retrieves Hikari's now dry 
pants and socks from the dryer and tosses them in the hamper with the 
rest of their clothes before leading Hikari to their room to get 
dressed.

###

When their mother gets home, she finds her two children in their room 
already dressed for bed, the boy in blue pajamas and the girl in a Pink 
nightie just short enough to show off the fresh pull-up she's wearing, 
the siblings playing video games together, Hikari nestled in her 
brother's lap.

Smiling down at her children, their mother comments, "Aren't you two 
just precious." before asking, "Did Hikari have any accidents while I 
was out?"

"No, mama!" the two lie in unison, matching innocent smiles on their 
faces.

Trusting her children too much to see through their deception, she 
replies, "I'm going to go start on dinner."

###

When bedtime rolls around, Hikari proudly announces, "I still dry!" As 
her mother removes her pull-up to put the girl in one of the thicker 
diapers she wears to bed.

"So you are," replies her mother, "I guess that means you get to try on 
a pair of the big girl panties I bought you while I was out tomorrow 
morning."

"Really?" cries the girl, Beaming up at her mother, "Thank you, mama!"

Sitting her daughter down on the floor, the older woman gives her 
daughter a pat on her diapered butt as she tells the young child, "Now, 
run off to bed."

"Nightie-night, Mama!" cries the girl as she runs off to the bedroom she 
shares with her brother. Seeing Taichi sitting on the side of the bottom 
bunk, she runs up to her brother, who catches her and pulls her into a 
hug and on to his lap. Whispering in his ear, Hikari happily declares, 
"Thank you, Onii-chan. Mama says I can wear big girl panties tomorrow."

"Glad to hear it." replies Taichi, happy to see his little sister happy 
and glad there's no signs of her tantrum from earlier.

When he finally sits her back on the floor, instead of climbing the 
ladder to her own bunk, Hikari asks shyly, "Onii-chan, can I sleep with 
you tonight?"

"Sure," replies her brother before adding teasingly, "But I'm not 
covering for you if you wet my bed."

"Onii-chaaaan!" she mock whines at his teasing before he scoots against 
the wall and she accepts his invitation to crawl into bed next to him.
