Notes
See the end of the work for notes
“Hey Mob-kun, hang back will you?”
Shigeo looked up from the free weight he was struggling to lift, attempting to
make his way to the rack. A bead of sweat rolled down the side of his face, his
chin, caught on his white shirt and blossomed. “What is it, Tome-san?” His arms
were shaking under the meager 5kg weight and blessed Hiroshi took it from him
and put it in its place.
“Just wanna talk to you for a second,” the girl said, her legs kicked up onto
the table, crossed over one another. Tome flipped a page in her magazine, not
looking at Shigeo or anyone else. The other members of the Telepathy Club were
already packing their bags, slinging them on, cleaning up snacks, wrapping up
their DS and Switch chargers.
Shigeo made a small sound of confirmation and made his way over to where he and
the other Body Improvement Club members had settled their bags. He had to set
Onigawara’s aside, to which he got a nervous “Oi!” from the boy who was still
so touchy, so gun shy, so scared, but he was able to dig around and find his
cellphone with some ease. Squatting on overworked legs, Shigeo flipped it open
and typed a quick text to the top of his few contacts.
Shishou, something has come up at school. I’m going to be late. I’ll let you
know when I’m leaving.
Shigeo remained in his squatting position, waiting for Reigen’s approval. The
Telepathy Club members were the first to leave, wishing Shigeo a good day as
they passed, which he returned without looking up from his small screen. The
Body Improvement Club continued to clean up around him, wiping down equipment
and making sure everything was in its proper place. Musashi was the last to
finally trail out, vacuuming up the crumbs the Telepathy Club left under the
table.
After one of the longest waits Shigeo had ever had to endure when it came to
his master speaking, just as he was trying to formulate a way to politely
reject Tome’s offer of one-on-one time, Reigen replied.
Yeah, no problem. It’s slow today anyway.
He’d been sleeping then.
Shigeo closed his phone and put it back in his bag, standing on weak legs, his
knees almost giving out, threatening to collapse him back to the floor. Musashi
grabbed his arm as he passed, helping Shigeo steady himself as his blood pumped
back to his dizzy head.
“Careful, Kageyama-kun,” he said good naturedly, offering Shigeo a large, warm
smile. Shigeo returned it, grateful to his friend who never judged him, always
supportive and pushing him in a positive way. Musashi reached behind Shigeo and
picked up his own bag, holding it away from his sweaty body. Shigeo knew the
other club members typically went to the gym for a quick shower and change, and
in the periphery of his mind, Shigeo longed to join them and shake the smell
off.
“Have a good afternoon, both of you.” Musashi was gone after that, leaving
Shigeo and Tome alone in the small, shared club room.
When Shigeo turned around to join Tome at the table, he jumped with a startled
sound to find her standing right behind him, magazine discarded.
“Uh- um- I-I,” Shigeo attempted. “Wh-…”
“I wanted to talk to you about something personal,” Tome said, a fist on her
hip, cocked to the side. She wore the same bored, passive expression she
usually did, her voice carrying the same deathly serious tone as when she
talked about espers and aliens and government conspiracies. She pointed
straight up, and Shigeo looked. When he saw nothing, he struggled to figure out
if she was talking about space again or if she was just gesticulating.
When she then pointed at Shigeo, head lolling to the side, he realized it was
the later.
Blunt as always, Tome asked: “Do you touch yourself?”
With a choked sound, Shigeo felt an electric shock run through him. His hair
shot straight up before falling back down to smack against his heated face. He
thought, feared, for a moment, he was going to pass out and ??? would take over
to save him from this situation in a way that would lack more tact than if
Shigeo had been left to handle it alone.
As Shigeo fumbled for words, Tome continued. “It’s fine,” Shigeo knew it was
fine, but the issue was in her asking! So boldly and in a public setting no
less! “I asked because I wanted to know if you ever thought about having
someone else help out.”
Shigeo wasn’t very good at reading situations, but Tome didn’t need to explain
any further for him to understand what she was going towards. He covered his
burning face with both hands, hair bobbing gently at just above his ears. He
could hear the free weights rattling in their rack.
“Have you ever heard of something called ‘friends with benefits’?”
Truthfully, Shigeo shook his head, still hiding behind his hands. He thought
friendship was the benefit, the benefit of braving social situations, of
putting himself out there, of pushing himself to grow. In exchange for his hard
work, he made friends.
Clearly there were still many things about society he didn’t fully understand.
Tome clicked her tongue and Shigeo heard a rustle of fabric. When he peeked
nervously, he saw that she had simply dropped her arm, straightening up a bit.
She was older than him, more comfortable with herself, and apparently her body,
but not by much. Shigeo chanced a glance up to her face and saw a blush forming
on her own cheeks. The sight helped release some of his nerves and he didn’t
notice that the window had been rattling in its pane until it stopped.
“Right,” Tome said, clearing her throat. She found Shigeo’s single eye from
behind his long, skinny fingers, and met his gaze. “It’s when friends who don’t
have feelings for each other do-“ and here she fumbled, voice cracking on the
next word, “s-stuff together. Just for fun, not for anything else. Just
because- because…” she cleared her throat again, finally averting her gaze. Her
fist remained at her mouth, hiding. “Because they trust each other.”
“Y-you-“ Shigeo’s voice came out hoarse, broken, an octave higher than usual,
“you want to do s-stuff like that….wi-with me?” His hands were shaking. Was
this real?
Tome’s face reddened further. “Only if you want to,” the words came out rushed.
She still wasn’t looking at him. “I want to- to try that sort of thing, but
you’re the only one-“ her voice dropped, quiet, Shigeo had to strain to hear,
“the only one I-…I trust with it.”
There was a long pause in which Shigeo didn’t know it was his turn to speak and
he felt his heart skip guiltily when Tome took it the wrong way.
“Like I said-!” She was back to her usual overbearing yet somehow still passive
demeanor. She made his head spin; it was like talking to a weird combination of
Reigen and Ritsu. “It’s only if you want to! We don’t have to do anything
you’re not comfortable with. Sorry I asked, I just figured…” she trailed off,
trying to get a read on a face Shigeo wouldn’t show. Her eyes darted up and he
was made keenly aware that his hair was still floating. “Well. Whatever,
doesn’t matter.”
Tome turned away from him, going back to her original spot at the table.
Stooping down, she grabbed the strap of her bag from where at some point in the
day it had fallen underneath the table.
It wasn’t until she was finished packing up her things and adjusting the strap
on her shoulder that Shigeo realized he’d just been silently standing there for
upwards of five minutes.
“Okay!” he blurt out.
Tome looked up from her backpack strap, embarrassed flush still dusting her
cheeks. There was a thick air hanging between them, an air Shigeo had quickly
learned was what awkward felt like. “What?”
“Okay,” Shigeo said a bit more secure. Slowly, he lowered his hands, worrying
his bottom lip and averting his gaze. “Okay to- for us- to you know…” he
fumbled, fingers twisting together at his chest, in his shirt. Tome didn’t
finish the thought for him and he realized he was going to have to make himself
clear. “We can…try doing stuff like that. T-…together.”
For a long, long moment nothing happened. Shigeo was nervous that he had
inadvertently ruined something. That in waiting too long to accept, he had
violated something unspoken and fragile between him and his friend. He feared
that maybe this heavy air would never leave, that they would be tainted. He
didn’t think so, but there were claws against the lobes of his brain, critical.
The longer Tome went just staring at him, the more and more the tension felt
like spoiled clothes, sour with dried milk. The more the rattling of the free
weights, and now the window again, sounded like Kageyama-kun don’t you like me.
The more the silence, the inaction, felt like watching the blood of his only
friend splatter under white sneakers, felt like gravel digging into his face,
palms, felt like the mewls of a cat—
“You’re shaking pretty bad.” Tome’s voice was cool, soothing. Her hands were
soft as they ran against his own. “We don’t have to.”
“It’s not that,” Shigeo choked out, relieved to see that when he traveled far,
far away from this moment, she had set her bag down and moved closer again. “I-
it’s not that…” the words were softer the second time, his eyes on her hands,
grounding. He hadn’t messed up, he hadn’t ruined it, he wasn’t in trouble, not
yet at least.
She was waiting again, and this time Shigeo realized it was his turn. “I was
just scared.” He swallowed. “I-I thought you were mad at me.” She snorted,
rolling her eyes, opening her mouth to speak, but Shigeo knew that if he
stopped now he wouldn’t recollect the courage to finish. “I want to. T-to try
at least.”
Heart wrenching pause before: “Okay.” The word was a whisper and Shigeo lifted
his eyes too late to not be caught off guard by her leaning in closer. She
wasn’t that much taller than him, but in that moment, he felt as though he was
standing at the foot of a mountain. His tongue dart out to lick his lips the
same moment she tried to press against them and she wound up kissing his
tongue.
Tome laughed, pulling back only a few inches. “Wow.” At some point she had
pulled his hands from his shirt, from each other, and was holding them between
them. “Well they do say first kisses are usually pretty awkward but that was…”
Shigeo felt shame run through his already cold blood, heard something fall with
a clatter behind him. Tome didn’t even look, too used to his powers by now.
Wanting to make it up to her he tried again, letting his lips settle on hers.
Was this still her first kiss or did he ruin that for her? Did it even count if
they didn’t have feelings for each other?
Tome’s hand at the back of his head kept him from spiraling too far outside of
himself. Even though she was pulling him up, pulling him closer, his now freed
hand hovering in mid-air, suspended, unsure, Tome didn’t deepen the kiss. It
remained chaste, if more firm. He didn’t know if he was allowed to touch her.
But he found that it didn’t matter just yet because he soon had to pull away,
gasping for breath. Despite her previously firm hold on his head, she allowed
him to move without much resistance.
“Jeez, Mob-kun,” she said, “you’re supposed to breathe out of your nose.”
Shigeo was left with the shocking worry that maybe that hadn’t been her first
kiss. She was a year ahead of him, she did have a fair number of friends in
Shigeo’s eyes. Maybe she’d messed around with people before. The thought of her
in this very room, with another Telepathy Club member, or at a small party, shy
and awkward and chiding some other boy- some other girl maybe even- Shigeo
couldn’t think about that. Tsubome was always the first girl his mind conjured
up, even if he was still reeling from his rejection. The thought of Tome and
Tsubome kissing as part of some game or dare at those parties Ritsu warned him
about where kids would drink alcohol and smoke- It was getting him too hot, he
had to lock that away.
He came back down from the clouds at the gentle pat pat of Tome’s hand against
his cheek.
“You gonna live?”
Shigeo tried to say “yes” but it came out as a throaty, guttural grunt.
Tome laughed again, shifting, and Shigeo realized they were still pulled up
close to each other. And that made him realize, with fear and shame and
embarrassment, that maybe the kissing, maybe the thought of Tome and Tsubome
together, had gotten him a little hotter than he had realized.
His first instinct was to pull back, drop to the ground, and beg for
forgiveness, but at the first twitch of his body Tome held more firmly onto
him. “It’s okay,” she said, “isn’t that what we’re trying out?”
Shigeo’s head was spinning, he couldn’t see straight, he couldn’t believe Tome
wasn’t disgusted by him, wasn’t pushing him violently away, wasn’t running off
to tell everyone about what a pervert he was, wasn’t telling the other boys he
attacked her, wasn’t riling them up to jump him in the bathroom, in the
hallway, in the parking lot, after school between classes walking home—
“Can I touch it?”
“A-ah-?”
Tome motioned between them, trying to keep her face passive but her blush
giving her away. “Can I touch it?”
“Ngh-“
The inflection of whatever word he’d tried to sputter out was enough for Tome
and she slowly, so slowly, reached her hand down and pressed against the
erection straining against the front of Shigeo’s gym shorts. He gasped, hips
stuttering, and Tome’s hand in his hair kept him grounded, kept him from
embarrassing himself too much. At first, she was only pressing the heel of her
hand against it, fingers wrapped loosely around his thigh, but the longer they
stood the more confident she grew in his consent and then Shigeo really thought
he was about to die because there was a girl holding his dick.
Tome gave a few loose-fisted strokes, humming softly. “I thought they were
bigger than this.” Shigeo was too busy seeing stars to feel insulted. She
didn’t stop stroking him, growing more confident as he doubled over, leaning
his forehead against her shoulder, panting heavily. “I guess it gets bigger as
you grow, like tits.” Shigeo opened his eyes blearily, realizing how close he
was to her tits.
“Ca-can I-?”
“Yeah go ahead.”
Shigeo reached up with the hand that Tome had first left dangling between them,
not even realizing he’d just been standing in the position she left him in like
a total freak. He cupped her breast, head spinning again as he gave a gentle
squeeze. Tome’s boobs were nothing to write home about, smaller than even
Shigeo’s small hand, but god it was a boob and it was a girl’s boob and it was
real and Shigeo thought he was dreaming.
As Shigeo gave a few emboldened squeezes, Tome sucked in a breath and Shigeo
realized that Tome was not wearing a bra. He realized this because, as his
fingers slipped over the soft cotton of her school uniform, he felt her nipple
pressing firm against him.
He really was going to pass out.
Instead of that, however, his knees buckled and thankfully he was leaning
mostly against Tome. She was able to catch him easily, hissing in annoyance.
“Come on, Mob,” she chided, “haven’t you ever watched porn before?” He had but
he didn’t think he had the strength to defend himself. “You’re not being sexy
at all right now.”
Tome practically dragged him over to the club table, Shigeo’s legs kicking
uselessly under him as his feet tried to find purchase on the waxed hard wood.
She rest herself against the edge, not quite sitting but not quite standing,
letting Shigeo recover from his boob-touch induced delirium.
“Alright,” she grunted, patting her hand on his back and Shigeo hadn’t even
realized she’d let go of his dick, “you clearly don’t know what you’re doing.”
Sitting up, Shigeo blurted out: “Have you had sex before, Tome-san?!” His hair
was standing completely on end again, and in his periphery he could see things
floating aimlessly about the room.
“What?! No! Of course I haven’t! God, Mob, I just know a thing or two!” Get a
clue get a clue get a clue “Come on I didn’t mean in like that come here- Look
I’ll help you out okay, I’ll tell you what to do and by the time we’re done
here you’ll be an expert! As your senpai and club president it’s my duty to
teach you everything I know!”
“I’m not a part of Telepathy Club, Tome-sa-“
“That’s not the point!” Tome beat her chest with her fist, pumping herself up
in a way that matched her smug, determined expression, careful of Shigeo who
she had tucked up against her. “The point is, I’m going to teach you so you
don’t embarrass yourself when you get with a girl you’re actually trying to
impress!”
“O-oh…” Shigeo’s hand fidgeted against Tome’s shirt. “But I am trying to
impress you.”
“Yeah well,” Tome returned to her usual expression, letting her arm drop,
“you’re not doing a very good job.”
Tome shifted them, making Shigeo support his own weight for the first time in
what felt to Shigeo like ages, tangling their legs together and having Shigeo
lean his hips against hers. “There, now j-just-“ She took hold of his hand,
hesitating, nervous, the blush was back.
With dawning realization, Shigeo’s eyes widened. Tome had touched him, now he
was going to touch her. His throat tightened up, all the blood in his body
splitting between his face and his dick, which he noted with absolute horror
was pressed up against Tome’s smooth, pale thigh, right below where her skirt
ended. His fingers twitched around Tome’s hand, both tense and just on the
brink of losing composure.
Shigeo only had a barely working understanding regarding vaginas. He’d seen
them in porn and in his sexual health textbooks, but it wasn’t like either of
those sources gave a play-by-play demonstration of how you were supposed to
jerk a girl off. Dicks were simple, easy, just grab it and hang on. Shigeo
could do that, once he’d learned how to reel in his powers enough to handle it,
at least. And this didn’t have anything to do with being an adult, so Shishou
hadn’t taught him, and this didn’t have anything to do with being socially apt,
so Ritsu hadn’t taught him, and this didn’t have anything to do with being God,
so Dimple hadn’t taught him, so when Shigeo mustered up all courage he could
scrape from within his heart and stuck his hand under Tome’s skirt, pressing
against her soft, damp underwear, he had no idea where to begin.
Tome let out a startled yelp, hips stuttering against Shigeo’s. His first
instinct was to yank his hand away, and he would have been able to if Tome
didn’t have an iron grip on his wrist. “B-bold,” she stuttered in such a way it
almost sounded chiding, but Shigeo could tell by the look on her face the tone
was directed at herself. Shigeo didn’t know if it was funny or insulting that
Tome felt bested by him of all people. But her eyes were closed and her jaw was
jutting out to hide how her lips were trembling and she continued to keep his
hand there, so he decided to just let it go and focus on the fact he was up a
girl’s skirt.
Keeping a firm grip on his hand, Tome adjusted herself against him, having to
open her eyes a crack as she did so but making sure to keep her gaze downcast.
Shigeo felt the softness of her underwear against his skin, feeling the way it
caught against one of his nails, how damp and warm it was. He was panting,
rocking his hips back against hers, hand gripping tight against the table.
“Right there,” Tome said breathlessly, positioning Shigeo’s hand where she
wanted it. “Just, you know-“ her eyes finally flit back up to his, and she
could see through the half-lidded haze he was less present than he normally
was, “just- rub it.”
So Shigeo rubbed it.
The keen Tome let out as she arched backwards into the desk, twisting one leg
around one of Shigeo’s, grip tightening around his wrist- the keen was enough
to cause Shigeo to snap his head to the club room door. He knew the student
counsel was roaming around, making sure students were gone and club rooms were
properly cleaned. The student counsel. God. Ritsu. What would his little
brother say if he caught him in such a compromising position?
He was brought back to the girl holding him in position when the nails of her
free hand dug into the fat of his arm. There was a flicker of other nails,
perfectly manicured and painted, neat and just long enough, digging into
clothing, skin, hair, but Tome sounded so good and felt so good and smelled so
good that the memory of Minori was gone as quickly as it came. Shigeo bent
downwards against her, feeling her chest heaving against his. He was panting
against her neck, warm and wet, sucking back in his own stale breath. The table
below them was shuddering and jumping with every twitch of Tome’s body as
Shigeo rubbed her off, humped against her sharp, jutting hip bone.
It was Shigeo’s turn to yelp out in surprise as a shaking hand wrapped around
his erection. The hold was too firm and uncoordinated (and that was saying
something considering it had been well established Shigeo was not an expert
when it came to sex), but he wasn’t complaining. In fact, he proved that Tome’s
inexperienced jerking was greatly appreciated by the way he moaned her name
against the damp spot on her school uniform.
In addition to his lacking sexual prowess, Shigeo was also not exactly shooting
massive, thick loads. But that didn’t mean he totally appreciated the mess he
made in his underwear. Underwear he didn’t have a fresh change of. Underwear he
was going to have to put back on after his shower, wear during work, and walk
all the way back home in. Maybe even though dinner, if Reigen decided he didn’t
want to be alone. Even still, Shigeo made absolutely no attempt to pull away
from Tome’s hand as he came, stilling every movement except the weak,
distracted pawing at her underwear.
“Senpai,” he whimpered when he’d finally managed to suck in enough breath.
“You’re doing so good, Mob-kun,” Tome panted, one hand rubbing soothingly at
Shigeo’s back. She was still panting, squirming. Shigeo hadn’t noticed just how
sweaty he was until now, how badly he must stink. “Come on, keep going, I’m-
I’m almost there.”
Shigeo tried to steady himself, sitting up so his weight would be off of her
and he wouldn’t be tempted to grope at her boobs any more. He placed his weight
on one arm, shaky from the work out and the waves of pleasure still
occasionally drifting through him. The right thing to do would be to keep his
eyes open, to look at her and watch for her reactions, to learn how to do this
right, to know if she really came or if she faked it for his ego like he heard
some boys in his class whispering about. Shigeo knew himself better than that,
though, so he felt barely any shame when not even five seconds into that he
squeezed his eyes shut, face hot.
It only took a few more minutes of careful, steady rubbing before Tome finally
reached her own peak. Once again she was arching up into Shigeo, gripping him
tight, coiling around him. He’d always been a mouse in her grasp. Shigeo
learned that he didn’t need his eyes to know this; it was like sensing an aura.
Not literally, of course, because Tome was completely normal, perfectly
typical. But he could feel the minute ways the hand on his back twitched, the
way her legs tightened and loosened around his, how her body was winding up,
hips instinctually twitching to guide him into a pattern, a rhythm. He could
hear how her voice hitched, how she tried to stifle moans that snuck out half
way as sputtering little sighs and gasps, trying not to pride himself with her
humming Mm’s that maybe could have possibly been the start of his well-warn
nickname. Using these subtle but powerful cues, Shigeo knew that he’d been able
to do what some of the other boys claimed was totally impossible.
Tome came back to herself much more quickly than he had, sitting up and looking
at him, tired.
“Did I do it?”
“Yeah isn’t it obvious.”
“No, I mean,” Shigeo chewed his lower lip, glancing away for only a second,
“did I impress you?”
Tome stared at him quizzically for a beat, two, before Shigeo saw realization
flash in her eyes. She laughed and ruffled his hair. He hadn’t noticed it had
bent back to the will of gravity until that moment. “Yeah,” she said, “you
did.”
They didn’t jump back away from each other like they’d been burnt, and there
was no awkward disengaging. Tome and Shigeo simply untangled themselves fluid
and natural, an organic end to a forced coupling. Tome returned to her
backpack, straightening up her uniform and looking for stains. Shigeo went to
his backpack and gym bag, riffling through the clothes, desperate to see if
he’d forgotten to unpack what he’d warn the previous day with no luck. Shigeo
sighed, resigned to his come-sticky fate. Maybe if it was really as slow as
Reigen indicated he’d be able to go home early. Maybe skip all together.
“That was nice,” Tome said from somewhere above him. Shigeo stood up, taking a
bag in each hand.
“Yeah, it was.”
The two smiled at one another and with a quiet, almost shy set of goodbyes,
they turned in opposite directions out the door.
