"She won't ever like you, Shigeo," Ekubo supplies unhelpfully as he watches Mob
watching Tsubomi interact with her friends from a distance, the boy's eyes
glittering with adoration and illusions of the possibility of a relationship
between him and Tsubomi.
Mob doesn't seem to hear him, eyes following Tsubomi as a blush creeps across
his face from the feelings rising up within him and warming him.
"Shigeo. Did you hear me? She won't like you. Ever. But I like you so why don't
we join forces? We can be together the way you and Tsubomi-chan could never
be," Ekubo says, going to float in front of Mob's face so that Mob focuses on
him.
Mob does, but his eyebrows also scrunch together and he gives Ekubo an
irritated look. "You're annoying," he simply replies, and with one last longing
glance at a laughing Tsubomi, he turns away and leaves, leaving Ekubo to seethe
in the air.
"Annoying, huh? You haven't seen me at my worst, Shigeo, and you don't want
to..." he mutters to himself, glaring at Tsubomi before suddenly getting an
idea, and he dissipates into thin air with a lingering evil grin on his face.
===============================================================================
Tsubomi approaches Mob one afternoon during lunchtime. She taps a manicured
finger on his tense shoulder that is turned away from her as he hunches over
his homework, desperately trying to solve this Maths problem.
He jolts when she touches him, and she has to stifle a little giggle at that.
Mob-kun had always been rather odd but adorable. His pencil falls to the floor
with a quiet clatter.
"Tsu-Tsubomi-chan!" Mob manages, face red as he stares up at her in surprise.
What could she want with him? He leans down to pick up his pencil first, but
then realizes that if he does that it might seem like he was trying to look
under her school skirt so he sits back up ramrod straight in his seat, a
peculiar expression on his face. "Uh, um, was there something you wanted?" he
asks politely.
Tsubomi smiles at him and Mob thinks that this must be a dream. The last time
she'd smiled at him was years ago when they were still small and had really
high-pitched voices. "Oh, nothing much. It's just... I've been having some
trouble with my Maths homework and I see you doing yours so diligently all the
time so I assumed you must be good at it. So..." she drags out her vowels, "I
thought I'd invite you over to my house later today to help me with my
homework. What do you say, Mob-kun?"
"Uhh, um..." Mob starts to sweat as he weighs his options. He could say yes and
out himself as a complete fool in Maths and disappoint Tsubomi, or he could say
no, I'm sorry right now and avoid her being too disappointed in him. If he told
the truth, maybe she'd be more forgiving of his inadequacy. But then again...
he really wanted to hang out with Tsubomi and this was a great chance to do so!
Alone, too! Just the two of them! Mob's conscience wavered. Ah.
"Yes." Ah! He said it. Oops. He hadn't really meant to make a decision so quick
but his mind was weaker than his heart and so he only followed what his heart
told him to say.
"Okay, great!" Tsubomi beams at him, placing down on his desk a neat scrap of
paper with the time and location of where they should meet after school to walk
back to her place together written in pretty cursive on it. In a whirl of long
hair and flowery perfume befitting of her beauty, she leaves the classroom,
just as the bell that signals the end of lunch rings and students start to
filter back into class.
Mob's adoring gaze slides from her fluttering hair to her handwriting and the
words on the paper suddenly appear hyper-clear before his eyes and he has to
clutch at his stomach. The butterflies were violent today.
===============================================================================
"So what's it like at home, Mob-kun? What do you do at home?"
"Er, homework... And I watch some TV..."
"I see." Tsubomi suddenly seems uninterested, staring off somewhere else, but
at least they're still holding hands, Mob happily notes. "Are your parents
always home?"
"Yes, ah, my mother is a housewife. My dad works normal hours, but he comes
home for every meal after breakfast."
His eyes follow Tsubomi's higher ones as her wide, glittering pupils gaze at
another boy across the street. The boy is taller than Tsubomi, which means that
he's even taller than Mob, and he has a nice hairstyle, Mob thinks. He
suppresses a sigh. Ekubo might have been speaking the truth after all. What did
holding hands even signify anyway? Even friends held hands.
But then Tsubomi suddenly squeezes his hand that is clutched in hers, and when
he looks up, she's smiling at him. "Why'd you stop talking, Mob-kun?"
"Ah? Oh, um, then what about your parents? Are they always home?"
"Nope," Tsubomi shakes her head, silky locks brushing againt Mob's cheek in an
almost flirty way. "My parents both work from sunrise to sunset, and they never
have time for me, which means they're never at home. Lucky us," she says
sarcastically, "But also, lucky us," she repeats in a different tone of voice
and Mob wonders what she means, but then she smiles at him again and all of his
thoughts slip out of his head onto the pavement below them.
===============================================================================
Mob was beginning to regret saying yes. He sweats and suffers for an
excruciating half an hour over the very first Maths question in Tsubomi's
notebook. Tsubomi watches him, resting her head on her arm that's on the table.
She looks bored, Mob observes quickly when his eyes flit up to glance at her.
He's about to open his mouth to confess that he in fact is a complete dunce at
Maths when she suddenly reaches out and shuts her notebook closed in front of
him and confesses first.
"I like you, Mob-kun."
"Hah? Ah, the Maths homework, I'm sorry I-"
"Forget the homework, it's boring. I said that I like you." She levels a gaze
at him, a look that, to Mob, seems to carry a burden of expectations and if he
can't meet them...
It takes some time for Mob to make sense of her words. Then he turns
unhealthily red and starts to sweat even more. He feels ridiculous. He wants to
laugh out loud, but then Tsubomi-chan might get freaked out by him and not like
him anymore. Best to reply coherently and casually.
"I like you, too..." Mob stutters out in reply, blushing harder than he's ever
had in his entire life.
"Really? Great!" She flashes a grin at him for several seconds then her sweet
expression changes to something more predatory. "Ne, Mob-kun... If you like me
will you do as I say?"
Without thinking twice, Mob nods like the good, eager-to-please boy that he is.
"Then... Kiss me."
It's unexpected and Mob is caught off-guard for a moment there, but he quickly
recovers. A kiss is easy. A kiss is what he's always wanted to have with
Tsubomi-chan. Easy.
So Mob leans over the table and kisses her, an innocent smush of the lips. It's
not enough for Tsubomi. Her arms grab him over the table and drag him towards
her, surprisingly strong arms lifting him over their homework and into her lap.
She's really strong. With Mob now in her lap, she controls the kiss, threading
her fingers a little too roughly through his soft hair and biting his tongue
and lips. Mob lets her. It's sort of exciting in a confusing way. A hard nip
that brings blood rushing through the cut in his lip makes him jerk away,
suddenly a little scared of her, but Tsubomi is stronger than he is physically
and she instead pulls him back even closer, this time bringing his limp hands
to her developing breasts, making him touch, encouraging him to squeeze them.
Things are going too fast for Mob to be comfortable with them. He licks at his
bleeding lip nervously. Tsubomi's grip on his hands is painful, and she's
crushing his stiff fingers against her chest, trying to entice him to touch. It
tightens and tightens the longer Mob stalls, so he finally unfurls some fingers
as best as he can through Tsubomi's grip, and he touches her breast. Through
her school uniform, he can trace the lace lining of her bra and the curve of
her soft breasts underneath. He paws at them, hoping that it's what she wants.
A thousand thoughts race through his mind but none pause long enough for him to
make sense of them, so he goes blank.
Tsubomi seems to like what he's doing enough to hug him tighter and she sighs
into his hair. "You're so cute, Mob-kun... Your hands touching me feels so
good."
Mob blinks, cheek smushed into her collarbone and his hands still against her
breasts. "Um, Tsubomi-chan... Maybe we should stop..." he suggests as he tries
to pull away because he's getting hard in his uniform pants but he's also a
little scared of her now and how strongly she's coming onto him. His previous
illusions and fantasies of her being gentle and sweet are fast fading. He had
always thought Tsubomi would be soft and lovely when they finally did stuff
together but this was going in a very different direction than he expected and
it's getting kind of unpleasant.
Tsubomi just tells him to shut up and throws herself at him again, locking
their lips together so forcefully that Mob is forced to fall backwards onto the
floor, his head hitting the wood with a loud thud. He groans in pain but
Tsubomi only giggles.
She then slides down his body like a little seductress, pushing his shirt up
out of the way and in a blur of events, Mob's pants are undone and his dick is
in her mouth and she's sucking noisily and messily, getting her saliva
everywhere.
"Your dick is so small and cute, Mob-kun, just like you," she takes her mouth
off him to tell him, pulling off his pants and underwear fully before going
back down on him. Mob grimaces embarrassedly, then lets a small noise slip out
when she expertly tongues around the head of his cock.
Despite the pleasure his brain is telling him he's feeling, he finds the
sensation of her drool dripping onto his abdomen rather gross and he shifts his
hips uncomfortably. He wants to push her away but if he does, would she ever
speak to him again? He didn't want her to never speak to him again. So he lets
her do what she wants to him even though he does shut his eyes tight and prays
that it's just a nightmarish wet dream.
Tsubomi keeps at it for a good while, the rhythm of her mouth slicking up and
down his cock never faltering. Mob's pleasure builds but at the same is beat
down by his internal mind battles. It's an odd game of push-and-pull, back-and-
forth with his orgasm; he's close but also so far from it because the
conflicting feelings in his system are muddling his head and hindering his
ability to surrender fully to the pleasure.
Finally she pops her mouth off his dark pink tip and grins up at him, tucking a
lock of hair behind her ears prettily and demurely, and Mob thinks to himself
how it's so jarring to see her like that after what just happened between them
the past ten minutes or so.
"You've lasted longer than I expected you to, Mob-kun."
Mob gives her a noise that briefly translates to an unconfident "I guess?" and
then she makes another move by crawling back up the length of his body. He
feels her skirt drag against the underside of his cock as she does so, and his
hips unwittingly jerk.
He's barely surprised anymore when she grabs his hand again and forces it down
her skirt and panties. His fingers touch hot flesh and he thinks, she's so wet.
"Make me moan, Mob-kun," she pleads, and Mob tries to, his fingers slipping
into her hot, wet vagina too easily. His inexperienced fingering is enough to
make her writhe about, almost cracking his frail wrist, so turned on she is.
Her strong hips jerk back and forth, making Mob's fingers slip out constantly.
When he pulls his fingers out of her panties later after she's cum for the
first time with a wail, they're coated with red. He spreads his fingers,
looking at the strings of reddish cum that hang from them in the light. His
eyes widen and he stops breathing. Fear hits him like a cinderblock to the
chest.
"It's okay," Tsubomi assures him, kissing his bloody fingers, and then she
presses her red lips to his own parted ones before pulling away to gaze at him
with lust-filled eyes. "I'm just on my period. You didn't hurt me."
Mob has gone deathly-pale. His dick has gone soft. Blood brings back bad
memories. Memories of his little brother lying unconscious on the concrete
pavement because of him.
"What? Are you afraid of a little blood? I'll help you get over your fear, Mob-
kun."
She proceeds to pull off her panties, blood-soaked pad and all, and throws them
to the side. She lifts up her skirt and bites the hem of it to hold to hold it
up, showing her pussy to Mob. Sparse pubic hairs cover her crotch region, and
further down Mob can see her clitoris peeking out from in between the thick
lips of her vagina. Her groin is red with smeared blood, and it drips out of
her in an odd rhythm to splatter onto the polished wooden floor. Mob watches,
fascinated yet horrified. He's never seen any part of a girl like this, and to
think that the very first girl whose parts he would see is Tsubomi... It would
have been unthinkable half an hour ago.
While he's off in his thoughts, Tsubomi places a hand on his cock and roughly
gives him a handjob. She strokes the flesh that hardens under her impatient
fingers, pulling the foreskin over and back from his tip. Mob's dick is the
perfect size for her dainty hands, and she loves watching the little head peek
through the circle of her thumb and index finger when she strokes downwards.
Mob isn't responding much but at least his dick is. Precum beads, and she
spreads it over his length quickly. When Tsubomi is satisfied enough with how
stiff his erection is, she swings a leg over his hips. She lines up Mob's dick
to her dripping, bloody pussy and settles down on it slowly, biting at her lush
lower lip and watching Mob's reaction through her long eyelashes.
When she drops her hips onto his, he jerks, as if woken up suddenly. He lifts
his head from the floor and blinks, and his eyes focus on hers. First there's
confusion, then fear slowly sets in again. The Tsubomi in his lap isn't the
Tsubomi he knows, or maybe he never knew her at all. His lips feel dry, crusted
with his own blood and hers, and he wants to lick them but he doesn't want to
taste that horrid metallic smell that already fills the air.
Mob starts to cry as Tsubomi rides him hard and fast. Her period is more than
enough lubrication to make the friction almost non-existant but Mob's cock
jabbing into her every time she bounces wildly on it is enough stimulation to
have her making guttural noises. It's scary, and Mob wishes he could detach the
bottom half of his body and crawl away from it and the girl that keeps sitting
on it.
The rubbing of Mob's hard cock against the front of her pussy feels amazing,
and Tsubomi angles her hips so she can keep most of the pressure on that feel-
good spot. Warm tingles run up her body, making her nipples hard and pointy
under her clothes. She groans and moans and gasps and under any other
circumstance, Mob would have found it all a huge turn-on, but this stranger who
was using him was only traumatizing him. She slides herself up and down on his
cock, leaving it bright red and wet, blood slowly pooling at the base of it and
dripping down the sides of his hips. Her rhythm gets more erratic and she
breathes harder. She's about to cum.
"I love you, Mob-kun!" Tsubomi cries out, palms pressed flat to the wooden
floor as she slams her wet, convulsing pussy down onto Mob's cock that twitches
in response. "Say you love me, say you love me back!" she wails as she cums,
thighs spreading and closing as she rides out the waves, and Mob grits his
teeth and throws his head back, hands balled into fists as his own orgasm is
literally forced out of him. He really doesn't want to cum in her, but she
refuses to let him go, squatting still, seating herself snug on his softening
cock again. It feels awful. He hasn't stopped crying.
After Tsubomi calms down and has stopped twitching she suddenly looms over his
face, too close for comfort, and her eyes are wide and so near that Mob could
count the red veins in her eyeballs if he wanted to. Her hands that are dirtied
with her blood and her cum come to grasp at the sides of Mob's face, nails
digging into the soft flesh of his cheeks painfully. She presses her forehead
to his too quickly, knocking them together, and whispers, "Say you love me,
Mob-kun."
Mob can't. He can't say those precious words to this girl who isn't Tsubomi-
chan. He closes his eyes instead and wishes she would slap him or something.
Anything.
"I'm sorry," is what he says instead, sobbing, and finally, after a long moment
of increasingly uncomfortable silence, Tsubomi stands, blood and cum dripping
rapidly from her crotch when she lifts herself off of his flaccid dick.
She doesn't look at him when she simply tells him to leave.
"I'm sorry," Mob repeats, getting up onto his knees and bowing to her, his
forehead touching the warm fluid-covered floor. His tears slide towards his
forehead and drip off his brows.
"Get up and leave!" Tsubomi shouts as she presses tissues to her crotch, and
the white blossoms with diluted red. Leaving some tissue stuffed in between her
thighs, she grabs more and squats with her legs together to start cleaning the
floor, ignoring Mob.
Mob lifts his heavy head and stands, his unwanted red wings framing his crotch,
cum splattered over his abdomen and down his thighs, blood and sweat dripping
from his forehead as snot and tears and drool slip down his face.
"I'm sorry," he says again, wiping half-heartedly at the mess on his face. He
needs her to know that he never meant for things to happen this way. Even
though Tsubomi practically forced herself on him, Mob still felt horrible about
cumming in her. He felt guilty for not being able to enjoy the moment with her.
He saw it as his own shortcoming, not hers.
Taking pity on him, Tsubomi stands from where she had been squatting and
cleaning the floor, and points to her right. "The bathroom is there. Show
yourself out when you're done, and lock the door behind yourself. And Mob-kun,"
she turns her head to look at him, and Mob cannot decipher her expression,
"Don't ever look at or talk to me again."
Mob thinks he sees her cheeks go crimson as she walks away to her bedroom but
he turns away as per her request and goes to the bathroom with his pants and
underwear to clean himself up.
When he's done, he leaves without a goodbye, though he says another apology as
he steps over the frame of her doorway to go home. He locks the door behind him
from the inside, and it shuts with finality.
He reaches home with his face wet from tears and snot again, and quickly leaves
to his room before anyone catches him and questions his condition.
===============================================================================
Tsubomi goes to lie down on her bed after her shower where she had thoroughly
cleaned out her insides of Mob's remaining cum and the blood that could be
washed away for now.
She closes her eyes, and a green spirit with red cheeks slips out through her
neck, leaving her to fall unconscious into a deep sleep.
Ekubo watches her for a while, then disappears through her bedroom wall.
"That should be enough to discourage Shigeo."

Murasakibara’s side and can rest his head on the other boy’s shoulder.
“Get off,” the larger boy demands with no fire. “You’re sticky.”
“It’s your fault,” Himuro says against the other boy’s clinging jersey. “Be
generous.”
“Get off,” Murasakibara says again, but he makes no move to enforce his order.
When Himuro doesn’t move for another minute, his arm moves in so his fingers
land heavy on the other’s waist, he heaves a sigh of resignation into Himuro’s
hair, and when Himuro drapes his arm over the other boy’s stomach he doesn’t
move away.
