Buttercup and the Professor by Imouto Kitten

As he watches Blossom fly off, Professor Utonium realizes he completely 
forgot about Father's Day and starts to wonder if his other two 
daughters have surprises planned for him or if Blossom's performance was 
a distraction while Bubbles and Buttercup made preparations.

Deciding his paperwork can wait and feeling a bit parched, he decides 
heading for the kitchen for some refreshment is in order even if he's 
not about to walk into another surprise.

However, the house seems to be abandoned as he makes his way from his 
office to the kitchen to pour himself a tall glass of lemonade and then 
heads for the living room and takes a seat on the couch.

However, as he's enjoying his ice cold beverage, the peace and quiet is 
broken once more as a familiar voice calls out, "Yo, Pops!" and 
following the sound to its source, he finds the most aggressive of his 
daughters, the raven-haired powerpuff having also discarded her 
signature look, but having gone in the polar opposite direction of 
Blossom.

The tights and mary janes are gone, replaced with black, leather boots 
even taller than the stockings Blossom had worn, the matching skirt 
scandelously short to show off the same amount of bare thigh Blossom 
had. Covering the green-eyed girl's flat chest is what looks like the 
remains of a black t-shirt with a green, broken heart in the center of 
the chest, that had already been several sizes too small, the sleeves 
having been torn off and the trunk mostly cut off, leaving ragged edges 
and barely more fabric than was found in the tops to the girls' bikinis. 
Buttercup was also sporting a black leather belt around her waist and 
smaller belts worn as bracelets and as a choker, all of them studded 
with emerald green rhinestones that looked sharp enough to do real 
damage if even a normal person backhanded someone while wearing those 
bracelets.

The professor didn't know fashion well enough to know if what his 
daughter was wearing qualified as punk or goth, but he had to admit the 
outfit fit her punch first, ask questions later attitude and added to 
her general aura of intimidation.

Taking in the way he's looking at her, Buttercup comments, "Like what ya 
see, Pops?" as she floats closer, letting him get an upskirt view that 
reveals she skipped putting on underwear as well, "I heard Pinkie went 
fer a ride on yer joystick and I want some of that myself."

Before Professor Utonium can even react to her declaration, his pants 
have vanished in a flash of pastel green, and the raven-haired powerpuff 
is floating above his naked crotch, her rounded boot stroking his 
quickly hardening member.

"Not a bad size." comments Buttercup with a smirk once she has him at 
full mast once more, "Can't wait to feel it filling me up." and with no 
further foreplay, Buttercup straddles his lap and impales herself on her 
creator's cock, driving it balls deep in one, swift motion. As she 
starts to gyrate her hips, she grins up at the professor as she taunts, 
"Don't just sit there, Pops. As hard as ya are inside me, I bet yer just 
raring to feel up my tight, little ass and my itty, bitty titties.

Needing no further encouragement, Utonium wraps his hands around his 
daughter's slight frame, easily covering her back from shoulders to 
waist with his interleaved fingers as his thumbs press into the lobes of 
the broken heart on her top, the tiny nipples beneath like a pair of 
glass beads as he rolls them under his thumbs.

"Not bad, Pops," comments Buttercup, picking up speed, "but you'll need 
to do better to get me off."

Keeping his thumbs on her nipples, Utonium slides his fingers down 
Buttercup's back and under her belt, her small stature letting him knead 
her firm buttocks at the same time as her non-existant tits.

"Hmmm, that's more like it," comments Buttercup, arching her back to 
make it even easier for the professor to play with both her rear and 
chest at the same time before adding, "But I feel you twitching like 
crazy... are ya already about to shoot off inside me?"

"Ye-yes! I'm going to cum!" cries the professor.

Giving him a devilish grin, she replies, "NOt so fast, Pops!" before 
clamping down almost painfully around his shaft and doubling her speed 
as she leans forward, "I bet there's nothing you want more than to shoot 
your little girl full of spunk like ya did to Pinkie, but unlike mis 
honor roll, I'm no closeted slut who'll just let a guy creampie her 
without working for it. I'm a badass adorable loli goddess of war and if 
you want the honor of spilling your seed in my cunt, you better pay the 
proper tribute!"

"Please, Buttercup, Please let me cum!" Cries the professor, too far 
gone to care about the ethics of what's happening, much less scold his 
daughter for her foul language.

"Hmmm... begging's a good start, but your goddess demands more worship!"

Desperate to please, the professor slides a hand down the back of 
Buttercup's skirt, cupping the entirety of her tight little ass, his 
middle finger sliding along her buttcrack as his other digits knead her 
tiny half moons. At the same time, he reaches up the front of her skirt 
with his other hand, and just as his thumb finds her clit,the middle 
finger of the other hand finds her rosebud, pushing hard against both, 
much to her satisfaction.

"YES! Finger fuck my asshole! Crush my clit!" cries Buttercup, 
continuing to gyrate on the cock buried in her cunt, "Heh, you really 
know how to please a little girl... bet you've secretly been a pedo this 
whole time and never made a move on me, Pinkie, or Blondie because we 
could make mincemeat of you if you ever tried something we didn't 
like... sure would explain why a man with multiple doctorates and no 
girlfriend was trying to make perfect, little girls in his lab."

Struggling to keep up fingering her clit and anus, the professor 
replies, "It's not like that." and he truly means that. Sure, he could 
imagine some mad scientist engineering their idea of the perfect lover, 
but he genuinely never had a sexual thought about any of his girls 
before today.

Dropping balls deep and grinding against him, Buttercup teases him 
further, "Come on, Pops, no need to deny it, I'm already riding yer 
joystick, not like I'm going to take ya to jail at this point... 
besides, I can feel how tight yer balls are against my butt, they're 
ready to burst. Come on, just admit you've always been a pervy, pedo 
prof who's always wanted to plunder powerpuff pussy and shoot yer nasty 
spunk deep in the bellies of little girls."

"I swear, I've never had such thoughts!" cries Utonium, certain that his 
daughter's assault would have made him shoot several times over if not 
for the death grip her twat has on his shaft.

"Well, if ya ain't going to be honest," StartsButtercup, "Perhaps I 
should just squeeze until it falls off... You know to protect innocent, 
little girls who can't defend themselves from your depravity... though I 
wouldn't mind keeping it as a toy for my own use..." and to illustrate 
her point, the professor can feel the ring of muscle around the base of 
his shaft tighten even further, erasing any doubt that his daughter 
could perform a penectomy just with her internal muscles.

Deciding he's better off playing along, Utonium cries out, "Oh, who am I 
kidding! You're right, I'm a pathetic pedophile of a professor, and when 
I started the Perfect Little Girl Project, I was hoping to make a 
perfectly obedient daughter I could mold into the perfect, little sex 
kitten... but then I had to smash that flask of Chemical X and ruined 
everything..."

"Good thing for you Pops, I'm a tigeress willing to reward your 
honesty," Comments Buttercup, moving even faster on the professor's 
prick, "Now, tell me what you want to do to your little goddess of war."

"I want to pump her full of my cum, to defile the innermost reaches of 
her forbidden fruit. I want her to use me as her personal cum fountain 
everyday for the rest of my life." As the professor admits to the urges 
her actions have awakened in him, she can feel herself approaching her 
climax, and deciding he's worked enough for it, she stops concentrating 
on keeping his cock clamped shut... not that it makes much difference, 
as when her climax hits, her internal muscles clench involuntarily, 
milking him for all he's worth, but too tightly to actually extract any 
of his seed, and its only as Buttercup collapses against his stomach and 
goes boneless in afterglow that her passage finally loosens enough to 
let his overdue ejaculation to erupt forth, splattering her womb and 
filling her tummy with an extra warmth as she basks in afterglow.

But the most aggressive of his daughters isn't quite done with him yet, 
and after recovering from her climax, she lifts off his cock and rises 
high enough to give him a worm's eye view of his seed running down the 
inside of her thighs. Crossing her arms, she mock scolds, "Look at the 
mess you made. You better be prepared to clean it up, Pops!" and before 
he can respond, she's spun around in mid-air and plopped her rear upon 
his face, the creampie he gave her starting to seep into his open mouth 
almost immediately.

Taking the hint, Utonium starts eating out Buttercup's pussy, the 
raven-haired girl moaning appreciatively, still sensitive from her 
recent climax.

"Not bad, Pops." Comments Buttercup after a minute or two of having her 
cunny cleaned by her creator's tongue, "I think you deserve me returning 
the favor. With that, she slides off his face and down his body towards 
his cock, taking the now limp appendage into her mouth and licking away 
their combined juices.

By the time she's done cleaning him, he's at half mast once more, but 
instead of finishing the blowjob, she merely takes to the air and gives 
him a saucy smile before declaring, "Happy Father's day, Pops!" and 
flying off, leaving the professor more than a bit tired and 
half-aroused.
