Summary
     “So let me get this straight,” Toshinori begins. “This kid needs to
     drink my semen every day or else he’ll die?”
     The doctor winces. “Well… yes, that’s about the gist of it.”
     “And the special sequence in my DNA breaks down if it’s exposed to
     oxygen.”
     “Um, as I said, one thing that makes you so rare isn’t just that your
     genes are a match to the patient’s but also that you have an
     unusually stable DNA pattern that allows your donation to make it
     unscathed to the patient’s stomach and bloodstream at all. Normal DNA
     can’t be passed on to other people, but yours has an odd quirk, that
     lets it give its strength to the recipient.”
     “Okay, so not only does he need to drink my semen, it’s got to be
     straight from the source?”
Notes
     I’m no scientist. This is basically porn with the tiniest bit of
     plot. Roll with it, folks. Also, this is pure trash. Hop-on-the-
     train-to-hell trash. Mind the tags and read at your own risk.
***** Chapter 1 *****
.-.-.
Toshinori’s head is spinning. He hadn’t expected this when he’d gotten the call
about being a match. A few weeks ago he’d let some agency swab his cheek, since
they were talking about sick kids needing donors, and DNA matches, stuff like
that. Toshinori considers himself an upstanding citizen – he’s a police
officer, even. They said that if his DNA was right, then he could help some kid
who’d die otherwise, and that the procedure was noninvasive. Of course he’d
signed up.
He’d figured that it wouldn’t amount to anything, so he’d been surprised when
he got the call this morning. Nevertheless, Toshinori called off work and went
to the clinic. Then, the doctors started throwing around phrases like ‘seminal
consumption’ and ‘daily dose’. They had a whole presentation and scientific
terminology, and all of that. But all Toshinori got was the bottom line.
“So let me get this straight,” Toshinori begins. “This kid needs to drink my
semen every day or else he’ll die?”
The doctor winces. “Well… yes, that’s about the gist of it.”
“And the special sequence in my DNA breaks down if it’s exposed to oxygen.”
“Um, as I said, one thing that makes you so rare isn’t just that your genes are
a match to the patient’s but also that you have an unusually stable DNA pattern
that allows your donation to make it unscathed to the patient’s stomach and
bloodstream at all. Normal DNA can’t be passed on to other people, but yours
has an odd quirk, that lets it give its strength to the recipient.”
“Okay, so not only does he need to drink my semen, it’s got to be straight from
the source?”
“Unfortunately, yes.”
Toshinori stares at the doctor. The doctor stares back apologetically. “And if
I agree, I’ll have to let some little boy suck my dick daily for the rest of
our lives?”
“No, of course not!” blusters the man. “It’s a developmental disease, so with
the correct therapy, the patient should recover enough to be function in two to
four years. And don’t think of it like, ah, oral sex. Generally in these cases
the donor, uh, masturbates themselves and the patient places himself in a
receptive position merely at the very finish.”
“Oh,” Toshinori says thinly. “So I’ll just be jerking myself off onto a—what’d
you say, fourteen year old boy?—for two to four years.”
The doctor winces. “I know how it sounds. Really, I fully understand your
reservations. Any decent man would have them.” He leans forward, eyes pleading
with Toshinori. “But, Mr. Yagi you must understand. This patient has a
debilitating developmental disorder. He’ll probably be dead within the decade
if he doesn’t get treatment, and with it he should be able to live a long,
healthy life. You are literally the only man in our database who’s a match. Of
course, no one can force you to do such a thing, but please at least consider
it.”
Toshinori covers his eyes with his palm. Christ. So his choice is to defile the
kid or let him die? He sighs.
“Alright, fine. I’ll do it.”
“You will? I mean, excellent! I’ll set up an appointment for tomorrow, at your
convenience. Whenever you’re off work, just let me know and we’ll arrange it.”
~
The doctor’s office is clean, like this is any other normal day. Toshinori sits
on an examination table in a dressing gown, like he’s going to have a procedure
done, rather than lift up the edge of the dress and jerk his semen into a
little kid’s mouth. The doctor had gone over the important parts with him: make
sure the boy’s mouth was closed over the head of his penis, so that no oxygen
got it, try to aim his shots towards the roof of the kid’s mouth so that it
didn’t hit the back of his throat and make him gag, and make the kid lick up
every last drop. Of course Doc didn’t phrase it quite like that, but Toshinori
got the point.
The boy is ushered in shortly, fully clothed since he isn’t the one whose dick
juice is important, here. Toshinori spoke with the kid’s mom on the phone
yesterday. Talk about awkward. Apparently the boy, Izuku, had been on the
waiting list for nearly two years, so they were desperate. Much longer and the
therapy wouldn’t have a chance of working. Mrs. Midoriya was so grateful, so
understanding. It was weird as hell to have a mom thanking you for letting her
son suck you off.
“Hey,” says Toshinori lamely. “You’re Midoriya Izuku, right?”
The kid nods. “Um. Y-you’re Mr. Yagi?”
“Please, call me Toshinori.” Please. Toshinori is already off balance enough,
he doesn’t need the kid on his knees calling him ‘Mr. Yagi’ on top of it. He
tries to smile and reaches a hand out. “You mind if I call you Izuku?”
Izuku shrugs. “That’s okay Mr- I mean, Toshinori.” He takes Toshinori’s head
gently. As a cop, Toshinori is used to getting firm handshakes, but Izuku’s
grip is soft, like the skin of his hand.
Really, Izuku is a pretty kid. He’s not gorgeous by any means. Most people
would call him plain looking, with messy, curly hair and big green eyes. His
face is soft with youth, but it’s smooth and blemish free. He looks nervous.
“Hey, Izuku. Come sit next to me for a second.”
The boy blushes, but obliges instantly, hopping up onto the exam table. Jeez,
he’s an obedient kid. The doctor had gushed on about Izuku’s positive traits
when trying to get Toshinori to agree: good grades, great attitude, sweet,
bright future, the works. Toshinori could see it easily. This is the kind of
kid that’s a pleasure to teach and parent. It’s a shame that he has such a
terrible illness.
Toshinori puts a hand on the center of Izuku’s back, right between his shoulder
blades. The boy flinches, but doesn’t move away. Toshinori sighs and pulls
away, placing his arm behind the kid so that he could feel it, but hopefully
wouldn’t feel boxed in. “I just wanted to tell you that you don’t have to do
this if you don’t want to.”
Izuku is silent, but Toshinori waits patiently for him. “If we don’t, I’ll die.
Mom said so.”
Christ. What a fucked-up situation. “Yeah, but it doesn’t have to be me. If you
don’t feel comfortable with me, then you can wait for someone else to match
with you.” Toshinori peers down at Izuku, but the boy doesn’t look in his
direction.
“No one else will match,” mumbles Izuku. “It took two years for them to find
you.”
Toshinori feels helpless. “Okay, but. You know that you can choose not to do
this, right? Yes, you’ll get sick, but that’s your choice. No one can decide
for you that you’re better off doing something you don’t want just because
it’ll make you live longer.”
That gets Izuku’s attention. The boy finally looks up at him. “Really?”
“Yes. If you want.”
The kid’s gaping. “No one- no one ever told me that, before.”
“Well it’s the truth,” says Toshinori firmly.
Izuku bites at his trembling lower lip. “Oh.” He gulps. “I don’t-” His voice
cracks. “I don’t want to die.”
Toshinori hops off the bench and faces Izuku, grabbing the boy’s shoulders.
“You don’t have to. If you want, we can do this and you’ll be fine. Or you can
decide not to. But either way, the choice is yours- not your mom’s, or the
doctor’s, or mine. This is something for you.” He pokes Izuku’s chest gently.
“Okay?”
The boy nods, and then sniffles. He leans forward until his forehead rests on
Toshinori’s chest. “Okay.” He wraps his arms around Toshinori’s middle, sliding
off the table so that their bodies are pressed together. “I want to live, Mr.
Yagi.”
“Toshinori,” he corrects gently. He strokes one hand through Izuku’s hair and
the other down the boy’s back. Despite himself, he feels his dick twitch with
interest. Toshinori wouldn’t describe himself as a pedophile. He’s had plenty
of fulfilling relationships with adult men and women, and never once felt the
need to seduce some little kid. But he can appreciate it, the soft suppleness
of Izuku’s young body, his sweet innocence. That’s the crux of it, this kid is
so freaking sweet, and Toshinori’s already a little bit in love with him. He
wants to cradle the boy’s fragile body, and protect him from the harsh things
in the world. And right now, the best way to keep Izuku safe is with
Toshinori’s cock.
“You’re really nice, Mr. Ya- I mean, Toshinori,” Izuku mumbles against his
chest.
“That’s how it should be.” Toshinori rubs Izuku’s head, and the kid presses
against him harder. He’s probably never had anyone touch him like this before.
“You should only do stuff like this with someone who’s nice to you, my boy.”
“Kay,” agrees Izuku easily. He shifts so that his cheek is pressed against
Toshinori’s breast. “But you’re nice to me. So it’s okay for me to let you put
your penis in my mouth, right?”
Fucking hell. “Uh huh,” Toshinori rasps, throat suddenly dry like the Sahara.
“If that’s what you want.”
Izuku starts drawing shapes on Toshinori’s bare back. He’s a big man, and the
hospital gown doesn’t stretch across his bulging torso very easily. The kid’s
arms only barely reach to Toshinori’s spine. Toshinori’s dick is getting hard.
He thought this was going to be like pulling nails, but a twisted, perverted
part of him can’t wait to see Izuku’s sweet little mouth wrapped around his
cock.
“Is it going to taste good?” asks Izuku innocently.
“Probably not,” Toshinori admits. “The- uh, my er, penis will taste fine, like
if you sucked on your fingers, but what comes out won’t. It’s kind of like cold
medication. It doesn’t taste good but you have to swallow it all down anyway.”
“Oh,” says Izuku, disappointed. “I tried mine, and it was really bad. I kind of
hoped that was just me.”
“Right,” Toshinori grits out. Jesus is this kid for real? “I can see why you-
why you’d do that. There are some foods that are rumored to make your… semen
taste good. Maybe we can try that.”
“Yeah,” agrees Izuku enthusiastically. He squeezes Toshinori tightly, although
the force is nothing for a huge man like him. “You’d do that for me?”
“Izuku,” sighs Toshinori. “I’ll do whatever it takes to make this better for
you.” His hard cock is pressing against Izuku’s stomach, and the boy giggles.
“That’s really nice, Mr. Toshinori.” Toshinori almost corrects him, but figures
that it’s close enough. Izuku pulls back and smiles at him. “I thought, um. I
mean- they teach you in school, not to let strange men, uh…”
“Do this sort of thing?” suggests Toshinori wryly.
Izuku blushes prettily. “Um. Basically, yeah. So I thought anyone who would-
who’d agree, um. They’d…”
“Be a pervert?”
“Yeah,” mumbles Izuku shyly. “But, you’re so nice to me. I don’t think I’ll
mind this so much, if it’s you.”
“Well it is me,” smiles Toshinori. He strokes a hand through Izuku’s hair
again, and the boy’s eyelids flutter. He leans his cheek against Toshinori’s
palm. “So do you think you want to do this, sweetheart?” If they waited much
longer, Toshinori might waste a dose of Izuku’s medicine prematurely.
“Sweetheart?” blushes Izuku.
“Do you not like that?”
Izuku shakes his head, and then nods. “N-no, I mean, I don’t not like it- I do
like it, I mean.”
Toshinori smiles and squeezes the boy against him. “Then I’ll call you that,
sweetheart. What about my question?”
“I-I-I think. Um. I want you to help me, Mr. Toshinori,” whispers Izuku.
“You think, sweetheart, or you know?”
“I know.” Izuku looks up at Toshinori wide-eyed. “I really like you, Mr.
Toshinori.”
Toshinori chuckles and leans down, kissing the boy on the forehead. “I really
like you, too, Izuku. Why don’t we get you comfortable?”
Izuku allows himself to be lead easily, and sinks down on his knees after
Toshinori stacks a couple of pillows there. “Okay, here’s what we’re going to
do, sweetheart.” The doubt is entirely gone from Toshinori’s mind. He’s too far
gone. “I’m going to take out my penis, and then you’re going to put the head of
it in your mouth. The head is the part that’s colored pink. You have to make
sure to wrap your lips around it tightly, so that no air gets in.”
Toshinori ruffles the boy’s hair while Izuku gazes up at him intently. “Then,
I’m going to rub my hand on my penis until the medicine comes out, alright?”
“Yes, Mr. Toshinori.”
God, Izuku’s such a sweet, obedient boy. “You have to swallow it all before you
open your mouth. And then I’m going to make sure to get the last drops out as
well, so wait for that too.”
“Got it, Mr. Toshinori.”
Toshinori smiles down at the cute kid and ruffles his hair again. Izuku hums in
pleasure. “Alright sweetheart. Are you ready?”
“Yeah. Thank you Mr. Toshinori!” grins Izuku.
Fuck. That’s it. Toshinori whips out his dick and Izuku’s eyes widen. “It’s so
big,” he whispers.
“Don’t worry, sweetheart,” pants Toshinori. “You’ve only got to take in the
head. See?” He pulls back his foreskin and shows the pink tip to the boy.
“Oh, that’s not so bad.”
Izuku leans forward and wraps his lips around Toshinori. “Fuck!” swears the
man.
The boy flinches back, and Toshinori’s cock slips out. “D-did I do s-something
wrong, Mr. Toshinori?”
“No!” Toshinori sinks a hand into Izuku’s curly hair, scratching his scalp
lightly. “I was just surprised, sweetheart. Try again.”
Nodding, Izuku leans down and fits Toshinori’s dick into his mouth. He licks
his tongue along the underside of Toshinori’s cock in order to guide it in,
since neither of them are using their hands. Toshinori shudders, but bites his
lip, trying not to surprise the kid again.
“Okay.” Toshinori takes a breath and tries again. “Okay, I’m going to wrap my
hand around my penis and stroke it, now. I’ll let you know when the medicine is
coming.”
“Mmmmhm,” hums Izuku, sending vibrations down Toshinori’s dick. He’s licking at
the head, maybe unconsciously. Or hell, maybe he likes the taste. Either way,
this is the hardest Toshinori’s been in years.
He grabs the base of his cock and moves forward until his knuckles bump against
Izuku’s lips. Toshinori keeps stroking and stroking, feeling his sweaty balls
draw up closely to his body. With his free hand, he rubs Izuku’s head, since
the kid seemed to like it. “You’re doing so good, sweetheart. You’re such a
great kid, Izuku.”
Izuku can’t smile since the corners of his mouth are pressed against
Toshinori’s hard dick, but his eyes look happy, gazing up into Toshinori’s own.
Toshinori’s hips twitch forward unconsciously, but Izuku doesn’t protest, just
grabbing at Toshinori’s naked thighs for balance. God. “Yeah, that’s it
sweetheart. Just a little bit longer.” He rubs himself harder, accidently
bumping the kid’s mouth a few times. “Okay, it’s coming now. Get ready Izuku.”
“Mmmhm.”
Fuck, that moan tips Toshinori over the edge, and he shoots his cum right into
the boy’s mouth. He barely stops himself from shoving his cock down with it.
Izuku’s face scrunches up in displeasure, but his throat works obediently as he
swallows rapidly. “That’s great. That’s so good, sweetheart.” He shifts his
hand from Izuku’s head to his cheek. “Just a little bit more.” Toshinori grunts
as he shoots one last squirt, and the boy laps it up greedily.
Toshinori’s chest is working hard, since he’s panting rapidly. “Okay. Okay,
Izuku. Just one last little bit.” He presses a finger to the base of his cock
and draws it forward, milking out the last drops. “Just take your tongue and-”
Toshinori moans softly when Izuku licks him without being asked. “Yeah, that
was perfect. Now just swallow that. Is it gone?”
“Mmmmhm.”
“Great.” Toshinori reaches down and grabs Izuku by his armpits, hoisting him
upwards. His softening penis falls out of Izuku’s surprised mouth, but he wraps
his legs around Toshinori’s waist reflexively. Once Toshinori has the kid
securely in his arms, he kisses Izuku’s cheek. “That was fantastic, sweetheart.
You did so good. I know that was hard.”
Izuku blushes and tucks his head against Toshinori’s neck, wrapping his arms
around the man’s shoulders. “It wasn’t that hard, Mr. Toshinori. You did all
the work.”
One of Toshinori’s hands is under Izuku’s bum, supporting the boy, so he rubs
the other one up and down Izuku’s back. “That’s not true. You did something
important, that you were nervous about. We’re going to help you get better,
okay?”
“Okay Mr. Toshinori.” He shifts. “No one’s held me like this since I was a
little kid,” he mumbles.
Right. The boy’s small for his age, but he’s still a fourteen-year-old.
Toshinori doubts his mother had been able to hold him up for the better part of
the last decade. “Do you like it, sweetheart?”
“Yeah Mr. Toshinori. It’s nice.” Izuku’s fingers flex against the skin of
Toshinori’s back. His gown had fallen off at some point during their session.
“Um, Mr. Toshinori?”
“Yes, Izuku?”
“Will you keep being my donor?” he whispers.
Toshinori squeezes the boy affectionately. “Only if you want me to,
sweetheart.”
Izuku nods against him. “Yeah. I- I want to. I, um, really like you, Mr.
Toshinori.”
“I really like you too, Izuku,” Toshinori chuckles. “I’d be happy to help you
any way I can.”
Izuku’s shoulders shake, and Toshinori realizes that the boy’s crying. He sits
down on a nearby chair, cradling the boy gently in his lap. “Shh,” he says.
“What’s wrong, sweetheart?”
“U-um. I’m just… really glad that you matched with me, Mr. Toshinori,” sniffles
Izuku.
“Oh sweetheart,” huffs Toshinori. “I’m really glad that I matched with you,
too.”
Despite his original expectations, Toshinori figured that the next two to four
years would be a lot better than he’d ever imagined.

Chapter Notes
See the end of the chapter for notes
.-.-.
After the third day in a row jerking his cum into Izuku’s mouth, the doctor
gave them license to take their activities home. It wasn’t convenient for
either Toshinori nor the Midoriyas to keep meeting up at the doctor’s office.
They worked out a good schedule (and meeting Mrs. Midoriya in person was just
as awkward as Toshinori feared, despite the woman’s best efforts). Izuku’s mom
worked as a waitress on the evenings. It turned out that the boy’s father was a
walk-out, who didn’t even have the decency to pay child support. The woman
could barely keep a roof over Izuku’s head, let alone the medical bills. She’d
offered shakily to compensate him for Izuku’s therapy, but Toshinori had
adamantly refused. He got more than enough out of their arrangement, not that
he was about to tell her that.
Normally, Izuku would go home and take care of himself all night, but Toshinori
was high up enough at work to be assigned day shifts consistently. Therefore,
it made more sense for the boy to take the train to Toshinori’s house after he
got off of school. Neither one of the Midoriyas expected him to do more than
give the boy his medicine, but Toshinori had every intention of looking after
the kid and making sure that he got a good meal in him.
So when he gets a knock on his door promptly at five thirty pm, Toshinori isn’t
surprised. He grins widely as he swings it open, seeing Izuku shyly standing on
the other side. The boy’s hands are clutching the straps of his backpack, and
he scuffs his toe against the welcome mat. “Hi, Mr. Toshinori.”
“Izuku! Welcome!” Toshinori steps aside. “Please, come in.”
Instead of entering, Izuku walks straight into Toshinori, tucking his head
against the man’s chest and wrapping his arms around his waist. Toshinori
chuckles and squeezes him gently, nudging him out of the way of the door so
that he can close it. “How was school, sweetheart?”
“Good,” mumbles the boy.
Toshinori runs a hand through the kid’s messy hair, and Izuku shudders against
him. Over the past few days they’d built up a bit of a routine. It turns out
that the boy is a cuddler, and Toshinori’s happy to indulge him. Whatever makes
it easier for Izuku to take his medicine. “Do you have any homework, Izuku?”
“I can get it done after I go home, Mr. Toshinori.” The kid doesn’t lift his
face from the man’s chest. “I’m a good student.”
Toshinori chuckles and turns the boy so that he’s tucked underneath his arm,
and leads him into the kitchen. “Of course you are, sweetheart. I just thought
that you could do it here instead while I make us some dinner.”
“Y-you don’t have to.” Izuku blushes and turns his face towards Toshinori, like
he wants to hug again. “I don’t want to be a bother.”
“You could never be a bother, sweetheart.”
So Toshinori cooks them a quick meal, just pasta with meat sauce, while Izuku
quietly does his work at the kitchen table. He makes sure to compliment the boy
and offer a comforting touch—a ruffle of his hair or squeeze to his
shoulder—every so often. The kid seems to need physical encouragement like a
flower needs the sun, and he’d perk up every time.
“Thank you, Mr. Toshinori,” he says when the man puts a plate in front of him.
Izuku looks down at it like it’s a five star cuisine. “You don’t… you’re
already so nice to me. You don’t have to be so nice.”
“Izuku.” He tips the boy’s chin upwards to meet his eyes. “I like being nice to
you. It makes me happy to see you smile.”
Toshinori is rewarded with a tentative one, and his own face splits in
response. “Yeah, just like that sweetheart. You’re going to come here every day
for a long time. I want you to be comfortable, like it’s home.”
Izuku’s smile widens. “Okay, Mr. Toshinori.”
Once they finish their meals, Toshinori places a firm hand in between the boy’s
shoulder blades and guides him to the living room, sitting them down on the
couch. “Do you want to watch some TV, sweetheart?”
“No, Mr. Toshinori.” He looks shyly up at the man. “Can I take my medicine,
now?”
Toshinori’s heart melts. “Alright, Izuku. Are you sure that you want to?” He
asks every day, even if the answer is the same.
“Yeah, I’m sure,” smiles Izuku. “Thank you.”
He rubs a hand through the boy’s hair, causing him to shiver and lean into
Toshinori’s side. “Okay, sweetheart. Let’s put a cushion on the floor, between
my legs.”
Izuku knows the rest by now, kneeling down on the pillow and waiting obediently
for Toshinori. This part is new. Normally Toshinori is already in a hospital
gown by the time that the boy’s face is so close to his crotch. Toshinori pulls
off his pants, twisting a bit to work them around Izuku. When he got home, he’d
only put on sweatpants, not bothering to wear anything underneath. He’s chubbed
up a little bit, but is still mostly flaccid. “Okay sweetheart, I’ll work on it
for a little while and tell you when to get ready, alright?”
“No, it’s okay Mr. Toshinori. I’ll help.”
Izuku rests his hands on the tops of Toshinori’s thighs, feeling at the hair
there. Toshinori had noticed that the boy was pretty curious about the man’s
body, and would explore a bit if he let him. The kid ducks his head and takes
Toshinori’s soft cock in his mouth, far deeper than they’d ever done. Since
he’s soft, Izuku can fit in all of him, nose bumping against Toshinori’s blonde
pubes.
“Hey, sweetheart.” Toshinori grabs the boy’s head gently and lifts him off
reluctantly. His dick twitches in protest. “You don’t have to do that.”
“I know, Mr. Toshinori.” Izuku stares up at him imploringly. “But I want to
help. You already do so much for me. I can make it easier for you.”
“It’s… this isn’t a chore, sweetheart.” Toshinori rubs the back of the kid’s
neck. “I do this because I want to help you get better.” And because it felt
fantastic, but that was neither here nor there. “If you want to help, you can,
but don’t do it just because you feel guilty.”
“I won’t!” promises Izuku. “I swear I want to help. Please?”
Hell, Toshinori isn’t a saint. He can’t say no to a pretty boy begging to suck
his dick. “Okay, sweetheart, but if you ever want to stop-”
“Thanks!” Izuku dives back down, eagerly suckling Toshinori’s dick to full
hardness. Of course, he’s not really giving Toshinori a blow job; he probably
doesn’t even know how. Instead he licks and sucks like a baby on a bottle,
slowly taking in less and less and Toshinori’s cock inflates. The man grabs his
shaft as soon as he’s able, giving himself a few firm pumps as Izuku helpfully
works his tongue underneath his foreskin.
“That’s so good, sweetheart,” mutters Toshinori. He rubs Izuku’s hair, just
like the boy likes. “You did such a good job. I’m so glad to have you, Izuku.”
The kid pulls back, a string of saliva connecting his lips to Toshinori’s cock
until it breaks. He smiles up at Toshinori. “Did I help?” he asks brightly.
“Yeah, sweetheart. You helped a lot.” Toshinori pulls Izuku’s face closer and
smears the head of his dick against the boy’s lips as if it were a tube of
lipstick.
He’s broken out of his spell when Izuku obligingly opens up his mouth and
suckles on just the head of his penis. Right, he’s doing this for medical
reasons, and it’s completely inappropriate for him to be smearing his precum on
the boy’s face like that. Luckily, the kid seemed to think that he was just
trying to get him to open up.
“Alright,” Toshinori says guiltily. “I’ll start using my hand, now.”
His cock pops out of Izuku’s mouth and the boy blinks up at him. “Um, Mr.
Toshinori?”
“Yes, sweetheart? Do you want to stop?”
Izuku shakes his head. “No, sir. I was just wondering, um. Can I use my hand on
you instead?”
For a moment, Toshinori can’t do anything but gape at the kid. Izuku blushes.
“I mean, it’s only that I don’t like it when your hand hits my lips. They get
sore.” He touches his fingers to his pretty pink mouth, as if in demonstration.
“Right,” rasps Toshinori. “Well, I don’t see why that would be a problem.
You’ll have to do a good job, though, or the medicine won’t come out.”
“I will! I promise, Mr. Toshinori,” says Izuku determinedly. “I can rub you
really good.”
Toshinori’s tempted to ask the boy if he’s had practice on himself, but that
seems to cross the fragile line between what’s medical and what’s sexual.
“Okay, sweetheart. Go ahead and give it a shot.”
Izuku reaches out and wraps a hand around him firmly, pumping a couple of
times. “Oh,” he says softly. “It’s so differently like this.” It’s said in a
whisper, and Toshinori doesn’t think he’s meant to hear, so he doesn’t respond.
Izuku has a tendency to mumble to himself and forget that other people are
listening. “Mr. Toshinori is so much bigger than me. My hand barely fits around
him. And the angle is so strange. I hope that it’s good for him.” Well, that
answers that question. Is this how the boy jacks himself off? Toshinori
shudders at the thought.
The boy pulls gently on the skin of Toshinori’s cock until his head comes into
view, and then licks his lips and slides them over it. Toshinori’s penis throbs
in Izuku’s hand, and the kid squeezes it, jerking it firmly. The man rests his
hands on Izuku’s head and cards them through his hair, scratching behind his
ears where he knows the boy is sensitive.
Surely enough, Izuku groans appreciatively and relaxes his jaw, letting
Toshinori sink a little further into his gullet. Now that the boy has taken
over masturbating him, he seems to moving his head a bit in time with his hand.
Toshinori doesn’t think it’s intentional, since the kid’s head-bobbing is so
slight. Nevertheless, it feels fantastic. “You’re doing such a good job,
Izuku,” he praises warmly. “Your medicine is going to come out in no time.”
“Mmmhm.”
God, Toshinori loves it when Izuku hums like that. He increases the pressure of
his hands, not pushing the boy down on his cock, but just trying to show his
appreciation. He reaches down and massages the kid’s neck, working out the
knots as best he could. Izuku moans and jerks his hand faster. Toshinori times
his strokes through the kid’s hair so that he brushes it forward when his head
is going downward, softly encouraging him to take slightly more of him into his
mouth. The boy eventually slides down an inch or two below the head of his
cock, bobbing back up as he jerks his hand forward.
“Okay, sweetheart. The medicine is coming now. Are you ready?”
“Mmmmmm.” The little minx licks the underside of his cock encouragingly.
Toshinori grabs either side of the boy’s head and gently pulls him forward and
back, working his mouth a little on his shaft. Izuku’s hard pumps faster now
that he doesn’t have to worry about his mouth.
“Ugh,” grunts Toshinori as he spills out onto the sweet kid’s tongue. Izuku
doesn’t even make a face. Now that he’s gotten a man-sized load of cum in his
cute little mouth for the fourth day in a row, he takes it like a pro,
swallowing immediately and not losing a single drop. He licks at Toshinori’s
slit without needing any encouragement, milking ever bit of semen that he can
get, hungry for his medication. He nurses on the man’s hard cock for a little
bit longer than necessary, and when it slips out of his mouth, Toshinori
immediately feels guilty. He’d crossed a line by encouraging the boy to work
his dick like that.
However, Izuku grins up at him, teeth stained off-white with a bit of his cum.
“Thanks, Mr. Toshinori!” he says brightly, just like he always does. “It’s a
lot better when I use my hand on you, so my neck doesn’t get so sore.”
“Oh sweetheart,” coos Toshinori. “Why didn’t you say so?” Like always, he
scoops Izuku up and kisses his cheek, cuddling the boy on his lap. “I didn’t
know that your neck was getting sore.”
“I didn’t want to be ungrateful,” mumbles the kid. “You’re so nice to me
already.”
“You could never be ungrateful, sweetheart.” Toshinori pulls Izuku in so that
the boy’s head is tucked under his chin. The kid doesn’t hesitate at all to
curl up on a grown man’s naked lap. He never does, probably unfazed by it after
swallowing Toshinori’s semen day after day. “I love helping you, and I want to
make it as good for you as I can, okay? Always tell me things like that.”
“Okay,” says the boy softly into his neck. “I really like you, Mr. Toshinori.”
“I really like you, too, Izuku,” chuckles Toshinori. They say this every day,
but the boy seems to need to hear it. “I think you’re so special, and I’m so
happy to spend time with you.”
“I’m not special,” refutes the kid shyly.
“Yes you are,” insists the blonde. “You’re my special sweetheart.”
Izuku seems to digest that for a moment, before snuffling and curling his hands
into Toshinori’s tank top. “Can I stay for a little bit, Mr. Toshinori?”
“Oh sweetheart.” Toshinori rubs a hand up and down Izuku’s back, cupping the
other one behind the boy’s head. “You can spend as much time here as you’d
like. It’s my pleasure to have you here with me.”
“You’re so nice,” says Izuku again wondrously. “You’re the best, Mr. Toshi. I
want to stay here forever.”
Toshinori laughs at the boy’s cute new nickname for him. “Well, sweetheart, you
have to go to school and home, and things like that.” Before the boy can
deflate too much, he continues. “But you get to come here every single day, and
I’ll be so excited to see you.” Oh yes. So excited.
“Okay, Mr. Toshi,” sighs Izuku happily. “Thank you so much for being my donor.
I really liked helping you make my medicine.”
Jesus. “You can do that tomorrow, too, if you want sweetheart.”
“I can?”
“Yeah, you did a great job,” he encourages. “So good. I think you’re a great
helper.”
“Alright, Mr. Toshi.” He can feel the boy’s smile against his neck. “I can’t
wait to help you again tomorrow.”
“Me neither, sweetheart. Me neither.”

.-.-.
The waterpark is fairly crowded, many parents deciding to bring their kids on a
warm Saturday. When Toshinori had heard that Izuku had never gone, he’d decided
to bring the boy. So he bundled Izuku, and his mother up in the squad car, and
insisted on paying for their tickets. Inko protested profusely, but Toshinori
was unwilling to budge. He knew that Inko couldn’t afford it, and there was no
price Toshinori wouldn’t pay to see the sheer delight on Izuku’s face.
“Mr. Toshi! Let’s do it again!” Izuku beams up at him.
Toshinori chuckles and ruffles the boy’s wet hair. “Alright, go save our spot
in line.”
Izuku immediately darts forward, trying to beat a large family that’s headed
towards the start of the queue. Toshinori follows at a more sedate pace. Inko
isn’t much for the water rides, but she seems happy enough sitting by the wave
pool with a drink so Toshinori leaves her to it. He’s pretty happy himself,
draping an arm around Izuku’s shoulders once he catches up to the boy. The kid
leans into him, grinning. Toshinori’s heart melts at the sight of it, but it’s
a sensation that he’s used to now, after a month of daily contact with Izuku.
“So you were telling me why Batman’s the best?” prompts Toshinori.
“Oh yeah!” chimes Izuku. “He’s awesome because he doesn’t have any super powers
or anything. And he isn’t even like Iron Man who has a really advanced suit of
armor. Yeah, he’s got some neat toys but mostly it’s just him and his
convictions.”
Izuku chatters on about various superheroes while they wait in line. It’d
hadn’t taken Toshinori very long to discover the boy’s obsession. He’d kept it
somewhat hidden, since it in’t exactly ‘cool’ for a fourteen year old boy to be
so into cartoons and comics, but Toshinori still tries to slip him some
paraphernalia whenever he could get away with it. However, this time someone
interjects.
“Excuse me!” cries a tall boy a few spaces ahead of them. “I couldn’t help but
overhear you saying that Batman is the best superhero. I regret to inform you
that you are wrong! It is the Flash who is the coolest.” Light glints off of
the kid’s glasses menacingly.
Izuku gapes, leaning against Toshinori shyly. Toshinori frowns at the new kid,
ready to tell him off for his rudeness. Luckily though, someone intervenes. A
man, probably in his early twenties, lays a hand on the boy’s shoulder.
“Tenya, what did I tell you about being too intense?” the man sighs. He turns
to Izuku and smiles. “Please forgive my little brother. What he means to say is
that he also really likes DC, and would you like to talk about it with him?”
Izuku smiles back tentatively, glancing up at Toshinori in askance. Toshinori
chuckles and gently prods the boy forward. As far as he knows, Izuku doesn’t
have any friends, or at least not anyone that he talks to Toshinori about.
It’ll be good for the boy to have some interaction with other teenagers. And
now Toshinori can see that Tenya wasn’t trying to be offensive, but rather is
just an awkward kid.
Izuku bites his lip unsurely, but goes up in line to hang out with the other
boy. Toshinori watches fondly as Izuku gets more and more animated throughout
their conversation. The two of them seem to be making fast friends, and by the
time Tenya and his brother get to the front of the line Izuku looks
disappointed.
“I will wait for you at the bottom of this ride, Midoriya!” exclaims Tenya
loyally, before he and his brother shoot down the slide.
Toshinori grins and grabs Izuku again. “Do you want to hang out with him after
this?”
“Oh, um.” Izuku grabs hold of Toshinori’s arm that’s draped across his chest
and chews on his lip. “Iida’s really nice. I’m here with you, though, Mr.
Toshi.”
“You’re here to have fun,” corrects Toshinori gently. “We’ve had a ton of fun
so far. I’d be happy if you made a new friend. Besides, your mom probably would
appreciate some company.”
Izuku flushes, but seems pleased. It’s their turn to go down the slide now.
This ride has a two-person raft, where one rider sits in front of the other.
“Heavier guest in the back,” says the bored employee.
Obediently, Toshinori sits in the back of the raft. Since he’s so big, Izuku
has to wedge himself between Toshinori’s legs, resting his chest against the
man’s back. Toshinori grabs hold of the handles, while Izuku grips Toshinori’s
knees.
“Ready!” Izuku beams up at the ride-worker, who can’t help but smile back a
little. The boy’s joy is the most infectious thing Toshinori’s ever
encountered.
“Yaahooo!” yells Izuku as they hurtle through the twists and turns. Toshinori
laughs out loud, leaning his head down to press his cheek against the boy’s
curly hair. He has so much affection for this kid that he isn’t entirely sure
how it all fits inside of him.
When they get to the bottom and pull themselves out of the pool that catches
the riders, the Iida brothers are waiting faithfully. Izuku brightens at the
sight of them, and Toshinori knows he made the right decision. Though the boy
is tentative at first, when the older Iida offers to watch the kids, he quickly
acquiesces and runs off with his new friend. Toshinori waves goodbye before
trudging off to find Inko, who’s luxuriating in the sun with what looks to be a
rather alcoholic beverage.
He heaves himself onto the vacant chair next to her, suddenly feeling the
energy drain of running around a waterpark, trying to keep up with an exuberant
fourteen year old all morning.
“If you think this is bad, it’s nothing compared to when he was five,” Inko
says sagely. “Where’d he get off to?”
“He made a friend in one of the lines. Izuku’s with him and his older brother.”
Inko pauses, a cautiously pleased expression on her face. “Oh. That’s… that’s
great.”
Toshinori hesitates, before continuing. “I get the impression that he doesn’t
have many friends?”
“No,” admits Inko. “He’s such a shy, sweet child. It makes him an easy target
for school bullies.”
“Oh,” says Toshinori lamely, disappointed even though he’d expected it.
Inko smiles at him. “It’s not all bad, though. He used to be so sad all the
time. He’d put on a brave face for me, obviously, but I could see through it no
problem. Since he met you, though, he’s been so happy.” Her eyes shine with
emotion. “I never imagined that we would get so lucky.”
Toshinori feels suddenly, horribly awkward. “It’s not luck,” he mutters. He’s
defiling a child, and despite himself he can’t help but love it every single
time Izuku’s pink lips wrap themselves around his cock.
“Toshinori,” Inko says, studying him. “I haven’t had this conversation with you
before, since I wanted to respect your privacy, but I think it’s time.”
“Oh?” asks Toshinori, sounding somewhat strangled.
“I’m not an idiot,” chuckles Inko wryly. “Toshinori, I knew exactly what my
son’s therapy entailed. I had a perception of what kind of man would willingly
allow a young boy to do what Izuku has to do. And since it’s his life on the
line, we would be forced to accept whichever match came to us.”
“I’m sorry,” murmurs Toshinori miserably.
“Don’t be,” smiles Inko. “That’s the thing. I made a devil’s bargain with
myself. I decided that I’d figure out how to pay for therapy, or treatment. If
it took twenty years for him to overcome the harm his donor would do to him,
well, at least he’d be alive for it.” She took a sip of her drink, using the
pause to wipe at her misty eyes. “I never even dared to hope that it could be
someone who is so good for him, in every sense of the word.”
Toshinori is completely flabbergasted. How could she possibly think that this
was good? “Inko I-”
“You love my son,” Inko interjects. “Don’t you?”
“I’m very fond of Izuku,” hedges Toshinori.
Inko snorts. “Anyone with eyes can see how much you adore him.”
It’s true. Although he hasn’t admitted it yet, he certainly loves Izuku. He’s
the kind of boy that’s impossible not to love. It’s a strange, twisted kind of
love though, somewhere between paternal affection and romantic passion. “Yes,”
Toshinori acknowledges.
“You love him, and he loves you back,” nods Inko. “Toshinori, you’d cut off
your own arm before you hurt him.”
“I’m not… I’m not entirely different from those men that you imagined,”
Toshinori sighs.
“Like I said,” laughs Inko. “I’m not an idiot. I can tell that the ‘medical’
aspect of this isn’t exactly a chore for you.”
Toshinori flushes. “Inko-”
“I don’t care,” interrupts Inko. She smiles at Toshinori. “You’re good for my
son, Toshinori. In every way. He’s never-” her voice hitched. “He’s never been
so happy. I’m grateful to you for being the source of that happiness. I’m glad
that you’re in Izuku’s life, and not only because of his illness. So Toshinori,
stop being so guilty. You may well be the best thing that’s ever happened to
him.”
Just then, Izuku comes scurrying around the corner, into their line of sight.
He makes a bee line towards Toshinori, collapsing onto the man in a heap.
“Oof,” grunts Toshinori, reflexively wrapping his arms around the kid. He feels
guilty for their contact, remembering that the boy’s mother is right next to
him. However, Inko is smiling at them indulgently, and with effort Toshinori
reins in his guilt. She approves- more than that, she’s grateful. And she makes
a good point. If she’s happy, and Izuku’s happy, why shouldn’t Toshinori enjoy
his relationship with the boy as well? This isn’t a traditional scenario.
Izuku’s going to be sucking his dick regardless of whether Toshinori pretends
not to like it.
Toshinori squeezes Izuku, finally allowing himself to enjoy the feeling of the
boy’s slick skin against his own. Izuku’s got his cheek pressed against
Toshinori’s chest, humming as the man rubs his back gently.
“Where did the Iida brothers go?” asks Toshinori.
“They had to go,” mumbles Izuku. “But Tensai got my phone number and Iida
texted me.” He glances over at Inko. “I think I made a new friend, mom.”
“That’s fantastic!” beams Inko.
“Thank you for bringing me here, Mr. Toshi.” Izuku’s fingers curl against his
ribs as he leans a bit more into Toshinori.
“It was my pleasure, my boy.”
.-.-.
It wasn’t long before they had to leave. Inko had a night shift and so
Toshinori drove her home. Izuku was going to be spending the night at
Toshinori’s apartment. He hadn’t wanted to put on his shirt after the
waterpark, complaining about the heat. It’s a bit illicit, having a shirtless
boy in his squad car. Toshinori has to resist peeking at him too much lest he
get a bit to, ah, excited.
When they get home, Toshinori shoulders Izuku’s bag and guides the boy upstairs
with a hand between his bare shoulder blades. Izuku eagerly grabs the keys and
unlocks the door, scampering inside. Toshinori follows him into the bedroom,
dropping the by the bathroom.
“Ooof,” he says as Izuku turns around and tackls him. Toshinori allows the boy
to wrestle him onto the bed, arranging themselves like they’d been laying at
the park. As he strokes his hands down Izuku’s smooth back, he regrets putting
his own shirt back on. Izuku had the right idea. Toshinori runs his fingers
through the kid’s still damp hair, and Izuku burrows his face down into
Toshinori’s chest, humming with pleasure.
“Did you have a good time today, sweetheart?” Toshinori asks softly.
“Yeah,” mumbles Izuku. “Thanks for taking me.”
“I love making you happy, baby boy. It really was my pleasure.”
Suddenly, Izuku pushes himself up to his knees, hands on Toshinori’s chest.
Toshinori grabs onto his hips to steady him, trying to ignore the way his
fingers nearly wrap around the boy’s bare waist. “You do, you know?”
“Hm?” asks Toshinori, frowning bemusedly up at Izuku, who’s looking at him
intently.
“You make me really happy,” insists Izuku. “I love hanging out with you. I
don’t ever feel, uh, bad or anything when I’m here.”
Toshinori peers curiously up at the boy. He rubs his hands up and down Izuku’s
waist a bit, ignoring the kid’s shivers, probably ticklish. “Were you listening
in on me and your mother talking?”
Izuku blushes prettily. “Just a little bit,” he mumbles. “Not on purpose!”
“It’s okay,” soothes Toshinori. “I understand.” He considers it for a moment.
What use is it to feel guilty when everyone involved keep insisting to him how
happy they are about the situation? He needs to focus on what’s best for Izuku,
and right now it seems that what the boy needs is reassurance that he’s making
Toshinori as happy as the other way around.
“I’m glad that I make you happy, sweetheart.” He smiles up at Izuku. “You know,
you make me really happy, too. It gets lonely in this apartment by myself, and
I always love having you here. You’re the best part of my day.”
That might’ve been a bit too much, because Izuku’s eyes are as wide as his
grin. Toshinori chuckles and reels the boy back downwards, squeezing him
against his chest. Izuku wriggles against him, and so Toshinori loosens his
grip. To his surprise though, the boy squirms downwards, and Toshinori doesn’t
quite understand what he’s doing until he starts mouthing at the front of his
shorts.
“Oh shiiiii-oot,” Toshinori corrects himself at the last second. Izuku notices,
if the huff of a laugh that the minx breathes against his dick is any
indication. He rests his hands on Izuku’s curly hair, scratching gently at his
scalp. The boy groans a bit, mouthing harder at Toshinori’s chubbed up cock.
After a month of daily blowjobs, Izuku has gotten far less tentative. He proves
it by hooking his fingers into the waistband of Toshinori’s shorts, pulling
downwards. Toshinori lifts his hips helpfully, and Izuku gives his bare cock a
lick before struggling to his knees to pull the offending article of clothing
off entirely.
Toshinori spreads his legs, letting Izuku settle between them. At this point,
the boy isn’t so much receiving his medicine as giving him a full-on blowjob.
It happened gradually, and Toshinori isn’t sure how much of it resulted from
his own gentle coaxing and how much was Izuku’s idea. Nevertheless, the boy
takes most of the cock easily down his throat. One of his hands rests on
Toshinori’s stomach, below his shirt, to steady himself. After all, Izuku
barely needs a single fist to wrap around the part of Toshinori’s penis that he
can’t take.
“You taste like chlorine,” the boy complains. Before Toshinori can offer to
shower, Izuku slurps his cock back down, pressing his tongue expertly against
the underside. His hips twitch upwards and he grabs the boy’s head, working it
up and down his dick. Toshinori knows Izuku’s limits, and is careful not to
push him to the point where he gags. He loves the feel of the boy’s hot, wet
lips sliding up and down his erection. Izuku allows himself to be manipulated
for a while, and then pauses at the top, working his tongue in between the head
of Toshinori’s cock and his foreskin.
“Oh fuuu… cru-ud.” Toshinori pants. “That’s so good, baby boy. You’re doing
great.” He rubs Izuku’s scalp appreciatively and the boy hums. Toshinori drags
the kid’s mouth down to his fist in response. The little minx knows what that
does to him. Izuku meets his gaze, a devious light in his eyes. The boy starts
humming, working his mouth and fist up and down Toshinori’s rock hard cock.
He slams his head back down onto his pillows, biting his lip so that he doesn’t
start swearing in response to the sensation. Toshinori feels the vibrations of
Izuku’s throat reverberating to his core, and his balls draw up tightly. He
barely resists cumming right down the boy’s hungry gullet. He doesn’t look away
though. The sight of slick cock disappearing in between Izuku’s cute pink lips
is almost as good as the feel of it.
Toshinori thrusts his hips upwards, and Izuku makes a surprised noise before
adjusting. He pushes the boy’s bangs backwards, and grins down at him. “You
ready?”
“Mmm hm,” hums the kid, redoubling his efforts. He wraps his free hand tightly
around Toshinori’s dick, and his cock looks obscenely big in Izuku’s small
hands. The boy can barely touch his fingers together around the girth of it.
Izuku’s hot mouth slides up and down the top half of his cock rapidly.
Toshinori can pull the boy’s head down and thrust his hips up rapidly, Izuku’s
hands preventing him from taking in too much. As he fucks himself into the wet
heat of the boy, Toshinori can’t help but imagine what it would be like to fuck
the kid properly. He wonders what kind of noises Izuku would make, if his mouth
were free to moan and sigh.
That image is too much for him, and Toshinori shoots his semen into the boy’s
mouth. Izuku rides out the man’s twitching and aftershocks like a pro, expertly
gobbling up every last drop. Toshinori can barely breathe, luxuriating in the
feet of Izuku’s sweet tongue sliding against the slit of his cock.
Toshinori gives himself a couple of minutes to relax before reaching down and
grabbing Izuku under his armpits. He’d learned that the boy would suckle on his
cock long after it went soft, never seeming to tire of it. Toshinori drags him
up, though the boy twists so that his back is to Toshinori’s front. Recently,
Izuku has preferred for Toshinori to spoon him during their post-orgasmic
cuddles.
Obediently, Toshinori curls himself around the boy, whose knees are drawn
halfway to his chest. He rubs his hand just below Izuku’s knee. “You were so
wonderful, sweetheart.” He presses a kiss to the boy’s curly hair. “That was so
good.”
“I liked it, too, Mr. Toshi,” insists Izuku. The boy shifts a little bit,
drawing his knees up tighter.
Toshinori isn’t quite sure why Izuku switched from facing him when they cuddled
to facing away, but regardless, it never takes him more than a few minutes to
relax. It’s not long before Toshinori can wrap an arm around Izuku’s chest,
rubbing a hand up and down the boy’s bare torso. He tries with limited success
to ignore the way that Izuku’s rear presses against his dick. He continues to
whisper sweet nothings into the boy’s ear, only stopping when he realizes that
the kid has fallen asleep.
Toshinori chuckles softly. He’s still got to get some dinner in the boy, but he
can’t complain. There will be plenty of time for all of that later. For now, he
shifts Izuku’s pliant body a bit to make him more comfortable. He wouldn’t
trade this for the world.

     Hm. I wonder why Izuku wouldn't want his front pressing against
     Toshinori's after their "activities". What could it be?
