Sango and Kohaku by Imouto Kitten

It had taken all of her skill at tracking a target and several retreats 
to avoid one of Naraku's incarnations being privy to their meeting, but 
Sango finally stood within striking distance of her little brother, 
Kohaku with no one else close enough to interfere. The preteen boy had 
been reduced to a mere shell of the kind soul Sango had known growing up 
thanks to the machinations of Naraku, and she needed their meeting to be 
as private as possible for what she had planned.

Stepping into the clearing where Kohaku is sitting, staring off into 
space, Sango deliberately gets her brother's attention in order to bait 
him into attacking. She easily blocks his thrown Kusarigama with her 
Hiraikotsu, letting the smaller blade's chain wrap around the gigantic 
boomerang before thrusting one end of the massive weapon into the soft 
dirt.

Before the less experienced slayer can compensate for his primary weapon 
being so effortlessly disabled, Sango has closed the distance between 
them, knocked the chain from his hand, and dropping to her knees,wrapped 
the much shorter boy in an embrace so tight he has no hope of unpinning 
his arms from his sides.

Once the boy stops struggling, realising his attempts to escape are 
utile, Sango risks moving a hand up to undo the straps holding his gas 
mask in place, letting the protective item fall to the ground and giving 
her the first up close look of her brother's entire face since that 
horrible day when he had been tricked into slaughtering their entire 
village, a day that feels like it was an eternity ago.

Running her fingers through Kohaku's hair as she examines his face, so 
familiar, yet completely devoid of the warmth she remembers, she can't 
help shedding tears as she comments, "It's despicable what Naraku has 
done to you. I can only hope the kind boy I remember is still in there 
and that this will reawaken him." With that, she captures her brother's 
lips in a kiss, his eyes going wide in the first sign of emotion he's 
displayed since she found him.

Interpreting his apparent shock as a good sign and capitalizing on it, 
Sango uses her teeth to crack the capsule of aphrodisiac she'd been 
hiding under her tongue and quickly pushes it past their joined lips, 
keeping her tongue in his mouth long enough to ensure the drug has time 
to be absorbed through the lining of his oral cavity.

By the time she breaks the kiss, there is nothing for Kohaku to spit out 
except the inert capsule, and while Sango can feel the aphrodisiac 
having an affect on her, her brother, between longer exposure, a greater 
area of exposure,,,,,, and significantly lower body mass should've 
gotten at least ten times the effective dose she did and is soon showing 
the signs of just that.

"Wha-What did you do to me?" asks the boy, holding his head as some of 
his old self breaks through the monotone that is one of the symptoms of 
Naraku's control.

"I just gave you something I hope will help me remind you of who you use 
to be." Replies Sango before pulling Kohaku against her, his head coming 
to rest between her breasts.

Reaching down, she finds him tenting his bodysuit, and undoing the 
concealed fly, frees his boyhood and starts to stroke him. Between the 
drug and her ministrations, her brother is helpless to break free of 
Sango's grip, and Kohaku is soon moaning at his sister's touch, pleasure 
partially overriding Naraku's influence.

Using her other hand to tilt Kohaku's head up, Sango smiles down at her 
brother as she asks, "Do you like that, little brother?" Kohaku is 
unable to give a coherent reply, but Sango interprets his moans and the 
way he's starting to buck his hips against her hand as affirmation.

Without any warning, Sango removes her hand from Kohaku's young cock, 
making the boy whine in need, but before he can voice any protest at the 
loss of stimulation, Sango has dropped to her knees, turned him around 
to face her once more, and taken his preteen prick balls deep in her 
mouth, making him moan even louder as she starts sucking as if trying to 
outdo Miroku's Wind Tunnel.

Another crack in Naraku's control makes itself known as Kohaku cries 
out, "Some...something is happening!" mere seconds before he shoots his 
load down Sango's throat.

As the boy recovers from what Sango suspects is his first orgasm since 
his disaster of a first hunt, Sango finds a soft spot in the ground and 
lays down, undoing the hidden fly of her own bodysuit to expose her 
femininity before commanding, "Come here, Kohaku, make love to your dear 
sister." Driven as much by instinct as passion thanks to Naraku's 
residual influence, Kohaku obeys his sister's summons, and once he's 
kneeling between her parted thighs, she guides his tip to her opening 
before placing a hand on his butt and pushing him inside her.

Once buried in his sister's folds, instinct takes over and Kohaku is 
soon fucking his sister like a wild buck rutting a doe at the height of 
mating season, both siblings moaning loudly as they give in to their 
shared desire.

Before long, Kohaku cries out, not a trace of Naraku's control in his 
voice, "San-Sango! I'm...I'm gonna cum!"

"Yes! Do it Kohaku! Flood your sister's womb with your incestuous seed!" 
cries Sango in a combination of ecstasy and triumph, the former from 
getting a hard fuck for the first time in far too long, the latter from 
seeming to have succeeded at breaking Naruku's hold on her brother.

Curling her spine to account for the height difference, Sango captures 
her brother's lips in a kiss just as the siblings reach their climax in 
unison, Kohaku flooding his sister's womb for the first time in what 
feels like forever as her pussy tries to milk his balls dry.

Breaking the kiss, Sango declares, "I love you, little brother." As her 
consciousness starts to fade from such an overwhelming climax after 
months of involuntary abstinence.

The last thing Sango hears before she passes out is Kohaku saying, "I 
love you, too, Onee-chan."

###

When Sango comes too, she is alone in the clearing, the only sign that 
Kohaku was ever there his seed seeping from her well fucked pussy. 
Though she apparently failed to free her brother from being Naraku's 
puppet, she's hopeful that brief moment of lucidity she saw from Kohaku 
as they shared an orgasm is proof that she can get through to her 
brother and that she's on the right track with trying to remind him of 
the fun they had together prior to that terrible day.
