****** Yo-kai Negasus: Alternate Ending ******
by BlueDragonKaiser
Summary
     Alternate ending to the Negasus episode where instead of his father's
     sock, Keita smells his mom's panties.
"Mom, I'm home!" Keita shouted as he walked in the house. He could tell by the
smell coming from the kitchen that they were having curry for dinner again, but
anything was fine with him at that point given that he didn't eat lunch. All
day at school he had been hounded by an annoying Yo-kai named Negasus who made
him do all sorts of naughty things. He even almost grabbed Fumika's butt when
no one was looking thanks to Negasus' influence before being stopped by his Yo-
kai friend Jibanyan, but deep, deep down that's probably something he's always
wanted to do anyway. Not only did he have a huge crush on her, but it was no
secret that Fumika has the best ass out of all the girls at Springdale
Elementary and isn't afraid to show it given those tight blue shorts she always
wears.
He walked in the laundry room to find his mother who had just put a load of
clothes into the dryer. "Welcome home honey!" she replied. "Dinner's ready but
first thing you need to do is wash your hands."
"Okay."
As his mom began to walk out of the room, she notices a pair of her panties on
the floor. "Oh dear, I'm so clumsy." She said while picking them up. "I've been
so caught up with the cooking and cleaning all day that I didn't even notice my
favorite panties didn't get washed with the last load. Oh well, guess they'll
just have to wait until the next one." Keita's mom put the yellow, cotton,
lace-trimmed panties in the laundry bin on top of the other clothes and walked
out of the room. After washing his hands, Keita spots the panties and suddenly
feels a strange force overcome him. It was the power of Negasus who followed
him home even after bothering him all day at school. Keita walked over to the
laundry bin and picked the panties up, holding them with both hands. It was
clear what Negasus wanted him to do but Whisper, Keita's Yo-kai Butler, and
Jibanyan tried to talk some sense into him.
"N-now wait a minute, Keita," Whisper began. "I know Negasus has made you do
some questionable things today, but those are literally your mother's panties
man!"
"Nyeah snyap out of it, Keita!" Commanded Jibanyan. "This is too much!"
Keita examined the panties closely. They didn't look stained or anything
meaning his mom didn't wear them too much this week. He checked the tag to see
that they were a size 8 which didn't make sense considering how big his mom's
ass is. Was she wearing them to turn on his dad? Was she trying to lose weight
to fit back into them? Either way he knew one thing, they were bunched up her
butt the whole time and she had a serious cameltoe going on.
"Keita please!" begged Whisper. "Think about what you're doing!"
"It's nyot like smelling a dirty sock, nya~!" Jibanyan shouted. "Underwear is
sacred, nya~! You'll be nyo different than an old ordinyary purrrvert, nya~!"
"I know these are mom's panties," Keita thought to himself. "And I know how
wrong smelling them would be. But if I don't, I'll never know..." Keita inched
the panties closer to his nose as Whisper and Jibanyan both begged him to stop
while Negasus, on the other hand, was laughing his ass off at the sight. The
panties were only millimeters away from his nose. His heart was pounding like a
taiko drum. After one last plea from Whisper and Jibanyan, Keita pressed the
panties against his face and took a big whiff.
An awkward silence then filled the room afterward with Whisper and Jibanyan
both in a state of disbelief with their jaws hanging wide open. Negasus was in
the corner snickering, waiting for Keita's reaction to the smell of his
mother's panties. Keita himself just stared at the panties for a few seconds
before saying anything. "I... I... I..." Negasus was holding his mouth shut
while still snickering. He just knew Keita was going to regret ever doing
something so deplorable and his reaction would be priceless.
"I love it." Keita finally said while blushing and taking another whiff of the
panties. "It's not a sweet scent nor is it a bad one. It's like... a perfectly
balanced odor. I could smell it all day." Hearing this put Negasus in a state
of disbelief as well. Was his power really that strong?
"Negasus truly is a fearsome Yo-kai." Stated Whisper. "Making a boy attracted
to the scent of his own mother's panties. How evil!"
"Um, Whisper," started Jibanyan. "I don't think Nyegasus has anything to with
that, nya~. I mean look at his face. Clearly, he's horrified by this too,
nya~."
"Well if that's true, then that means..."
The two both look back at Keita who's still smelling the panties and has them
pushed up to his face while swaying his hips left and right.
"I can't believe this," Whisper said in disbelief. "Negasus made him smell the
panties but he's attracted to the smell on his own. My master is an...
olfactophile!"
"Nyooo!" shouted Jibanyan. "Eh, what's that, nya~?"
"It means he's sexually aroused by scents and odors. In this case, the scent of
panties that have been worn by a beautiful woman! Who also in this case just
happens to be his own mother!"
"That's sick, nya~! Keita, you're a giant purrvert, nya~!"
Keita was too lost in the scent of his mother's panties to even pay attention
to what his friends were saying. Soon he felt himself growing erect so he
started rubbing his crotch with one hand and smelling the panties with the
other before falling to the ground.
"I'm outta here." Stated Jibanyan as he began to leave the room. "I can't
believe I'm friends with a guy who gets turned on by the smell of his own
mother's panties, nya~."
"I'm so disappointed in you Keita." Whisper cried while also leaving. "I can't
even look at you right now!"
Negasus began to leave too, leaving behind his Yo-kai medal as a sign of
defeat, but he hoped Keita never called him after this. Funnily enough, the
face he made on the medal is similar to the one he made after seeing how Keita
reacted to smell of his mother's underwear.
Keita ignored his friends' comments while still stroking himself to the smell
of his mom's panties. Soon he became completely erect to the point where his
pants were too tight in the front. "Well, regardless of how right or wrong this
is, it's too late to turn back." He said. He unbuttoned and unzipped his pants
causing them to fall to his knees. Before taking his briefs off, he noticed
that he already had precum as indicated by the throbbing wet spot where the tip
of his penis was. "Much too late." He then stripped the briefs off causing his
wang to bounce for a for a few seconds and kicked his pants and briefs away and
continued his pleasure session. He sat on the ground and gripped his wet cock
tightly, stroking it up and down with the panties pressed against his face.
Then the unthinkable happened. He began to fantasize about his mom wearing
nothing but a naked apron and those tight yellow panties while cooking dinner.
He imagined himself sneaking up behind his mother and surprising her by
pressing his face against her panty-clad ass with that wonderful feminine scent
filling his nostrils.
"Keita!" his fantasy mom exclaimed. "You know that isn't okay!"
"Bwah!" fantasy Keita screamed while blushing and falling back. "I'm sorry mom!
I don't know what came over me! I just... Really, really wanted to know how
your panties smelled for some reason. And I have to say, I really enjoy that
scent... A lot."
His mom began to blush as well and noticed that he was getting hard. "Well... I
suppose it is my fault to begin with. I wanted to surprise your father since he
works so hard, but I forgot you're at that age now. So by all means..." Keita's
mom stood over her son with her panties and cameltoe in his line of sight.
"Smell your mother's panties as much as you want!" She then fell on top of his
face, smothering him with her groin but not too much so she wouldn't cut off
his breathing.
Fantasy Keita was so turned by this that steam began to come out of his nose.
His cock throbbed with so much excitement that it felt like it would burst any
second (symbolizing how close he was to an orgasm in reality). Even Keita's
fantasy mom began to moan and get hot as Keita pressed his nose against her
plump vulva, thus stimulating her clitoris. "I'm so proud of you, Keita," she
said while trying her hardest to keep her composure. "You're just 11 but you're
already becoming a man so quickly. Soon you'll be able to please other
beautiful girls this way and many other ways but for now, show your mother how
much you enjoy her scent by cumming lots! Do it Keita! Please your mother!"
Keita took one last big whiff while (in reality) gripping his throbbing cock as
tight as he could stand it and felt himself climaxing. He and his fantasy
mother both moaned with their eyes closed and faces completely red as ropes of
stringy white cum shot from his dick and onto the floor while the panties were
pushed against his face. The strings then became a single hanging droplet which
took a minute or two before falling. With his orgasm over, Keita ended his
incestuous fantasy and removed the panties from his face. His heart and penis
began to calm down as he took a deep breath. "That was amazing," he said with
his eyes closed. "I never thought worn panties could ever have such an alluring
aroma." Keita's relieved smile turned into a look of concern. "Still, it's
really not okay for me to be fantasizing about my own mother like that. I mean
her scent is heavenly, but still."
Keita put his arms behind his head and looked up to the ceiling. "I guess I was
just too far gone for my conscience to get the better of me." He then closed
his eyes for a minute before realizing something. "Wait a minute! If mom's
scent is this good then that means other girls' scents are just as good if not
better! Including-" Keita began to get hard again and make a perverted face
where he looked up to the sky, his nostrils flared up, and his smile made it
look like he was drooling. "Fumi~."
"Keita are you alright?" His mom asked as she suddenly walked back into the
laundry room. "Your food will get col-" Keita's mom noticed the semen on the
floor, Keita's nudity and guilty expression, and the fact that he was holding
her favorite panties. It didn't take her long to connect the dots and she
slowly started to get pissed.
"N-Now wait a minute mom," Keita stammered. "This is just... I... I mean I'm
becoming a man right? So this is normal behavior! A-And once I get older I'll
be a perfect husband because I practiced as a kid! So you should be proud that
I'm growing up so fast right!?"
Every word Keita said pissed his mom off even more. Anger veins started to
appear on her fists and her head, her glasses began to glow, and her hair even
began to flare up. "Keita Amano..." she started. Finally she grew horns out of
her head and her teeth became sharp. "You are in so MUCH TROUBLEEEEE!" Her
shout was so intense that it could be from deepest regions of space. No one
knows what happened to Keita afterwards but it's said that his mother took
extreme measures to ensure that he never masturbated again.
