Saitama x Genos

Genos had gotten some... Modifications that are very helpful in his new relationship

with his teacher.

FLUFFY FLUFF SMUT

saitama x genos

-------

This... This was definitely new.

This intense heat that made Genos's circuits cut and spark- this definitely wasn't there before. Genos

sat in he and Saitama's bedroom, perplexed by his own body. Yesterday Genos had went and gotten

upgrades for his body, one of the upgrades being one Dr. Stench forced upon him learning about he

and his teachers new relationship.

"You and Saitama are dating?!" Dr. Stench exclaimed, looking away from the

complicated circuits that were opened on Genos's body and looking at the plain faced Cyborg.

"Yes. Is there a problem with that?" Genos's asks stoically, partially surprised by the doctors

reaction. Normally the man is happy when Genos speaks about his teacher, especially if it's a

moment that progressed their relationship. Now that he and Saitama-sensei are of icial he thought

the doctor would be thrilled.

"No! There isn't! Except for... Well, have you two done anything yet?"

"I'm not sure what you mean by that Doctor." Genos replies, his arm mechanically twitching

when the doctor pulled a certain wire. The doctor remained silent for a moment, trying to think of a

proper way to explain the intimacy that comes with a relationship. Especially one involving two men

(well Cyborg men).

"I'm talking about sexual things Genos. I think I may need to modify your body a bit.."

"But I believe my current body is suf icient. There's no need for modifications."

"Trust me, there is."

And now after returning to the small apartment that he and his teacher/boyfriend share- he's learning

what these modifications were. Genos has never really taken time to explore his lower regions on his

mechanical body, never having a reason too really. But when he was told to research sex, seduction,

and gay relationships- he came across things that... heated him up. Down there. A new and honestly

pleasurable feeling has made itself known, so Genos took a break from studying and instead opened

the panel on his pelvis revealing the silicon ***** that doctor had given him. One modification,

Genos notices, was the clear liquid beading at the slit from his arousal. Genos was embarrassed and

even worse, partially turned on by the fluids he produced. His circuits were hot and steaming,

making his head swim in a fog. Another modification was the act of self pleasure, one Genos never

once even considered trying out. He was on the path to revenge before, never thinking about

anything but that revenge, but now that hes with Saitama... It's different. Though he still feels the

anger from his past, it isn't as present in his life. He has things he cares about now. Saitama showed

him how to... be human again. Saitama... Saitama.

Genos gasps when he feels his own hand wrap around his wet *****, the pressure creating an intense

feeling to erupt down there. He doesn't know why his hand did that, but the more he allowed himself

to think of his teacher the more his hand moved up and down. Genos thoughts about his sensei's

strength, his absolute beauty in battle, the way he's so selfless, his rippling body... The way his eyes

turn so serious when he's upset, the way his body glistens in sweat after his work out.. The way he

makes Genos's heart swell when he tells him he cares about him. Genos's hand has begun to move at

a rapid pace, and Genos realizes he was going to ejaculate soon.

"Sensei!" He cries out as he cums over his own chest, his body shutting down for a split second

making him collapse on the bed behind him. He breaths heavily, lost in the feelings of an ******. Is

this what the big deal was? ... Genos realizes he liked it. A lot. He loved thinking about his teacher

and feeling good.

"That was quite the show you put on for me Genos."

Genos jumps forward, leaning up quickly and seeing with wide eyes that his boyfriend was leaning

against their doorway to their bedroom, his arms crossed and his eyes taking in the messy and

flushed form he must have.

"Sensei! This isn't what it looks like--"

"What it looks like to me," Saitama interrupts, walking forward until he stood in front of Genos,

"Was you were touching yourself, while thinking about me... Am I right?"

Genos gulps, fiddling with fingers in embarrassment because he knows he can't lie to his teacher,

"Yes, Saitama-san."

Saitama suddenly leans down, so that his lips were next to Genos's ear before whispering, "I think I

might join in on the fun."

Genos flushes, his wires heating up and silicon ***** twitching at the promise. He and Saitama

haven't ever done anything more then kissing, but Genos was sure he was ready for more. Especially

now that he has all the things he needs to actually take it farther, his knowledge on the new foreign

world full. He understood now; lust, pleasure, wanting, sex itself. So when Saitama pulls him in for a

hard kiss- he knows Saitama wants him too. Just as much as he wanted his teacher. Genos kisses

back eagerly, getting lost in the way Saitama managed to move his tongue against his, the way he

managed to slowly push him back until he was laying on his back on the bed.

Saitama pulls from the kiss once Genos was laid down, and moves back so he could see the silicon

***** that was leaking in pre come.

"Is this one of the new upgrades you told me you were going to have?" Saitama asks, his voice

heavy with lust and wanting. He licked his lips seeing how wet Genos was for him, his ****

twitching in his suddenly too-tight-pants. Genos can only nod his head, all coherent thought thrown

out the window from the mind bottling kiss his teacher managed to give him. Genos was just riding

on emotions right now, which is rare for him to do. Usually he was always full of fact and figures,

only his boyfriend managed to make him stop thinking and to just feel. To stop evaluating his senseis

heart beat and to just press his ear against his chest, to stop taking in the rising heat of his boyfriend

and to just press his lips against his to feel it, to not predict the way sensei would move to match it

and to just follow his lead. Sensei helped him be human again and Genos loved him so much for it.

"Ah!" Genos cries out when a sudden immense pleasure comes from the *****. He looks up slightly

and nearly gasps seeing that his boyfriend had his lips wrapped around the head of the ****. Genos

recognizes this as ********, and his toes instinctively curl in delight as his teacher sucked on the

head.

"O-Oh Saitama.." Genos moans, and he hears Saitama groan in delight from the way Genos dropped

the honorific title and just called him by his name. Saitama pulls off of Genos's now throbbing

erection and looks up at him with pleading eyes,

"Say it again."

"S-Say what again?"

"My name. Just my name."

Genos takes a moment to take in the desperate face Saitama-san looks at him with. The way saliva

makes his lips shine in the low lighting of their bedroom, the way his cheeks was a light pink from

sucking him off, the way his eyebrows scrunched together in begging.

"Saitama.." Genos says, his voice lower because of the sensuousness behind the name. Even Genos

got turned on more by saying his boyfriends name with familiarity. Saitama's bottom lip gets drawn

back by his teeth from the hot way his boyfriend said his name, the way the normally stoic cyborg

looks so human the way sweat clinged to his body, the way his Amber eyes were clouded in lust, the

way his body trembled when Saitama touched him... Saitama feels stupid for not doing this with

Genos before. He was so damn sexy and now Saitama finally gets to explore the body he

masturbates too.

Saitama leans forward and pressing his lips against Genos's neck, biting down on the skin(?) that was

there. Genos gasps from the pressure, the tingling feelings coming from his neck feeling so real.

Saitama places kisses all over Genos now, his neck, cheeks, chest, stomach- spreading his love all

over Genos. He was taking his time with Genos, loving his body with everything he had. Spreading

kisses and his affection all over the glorious body his lover had.

"I love you Genos." Saitama murmurs against Genos's thigh, in the middle of leaving a hickey on the

inner thigh.

"I-I love you too Saitama." Genos manages to pant out, once again leaving out the honorifics and

just calling his lover by his name.

Saitama groans again and feels himself shudder from his name leaving Genos's lips, and unable to

continue with any more fore play he pulls off his shirt, smirking when he catches Genos staring at his

toned body, then throwing off his pants. His pulls of his boxers and his erections comes out freely,

hitting his lower stomach. Genos's eyes widen at the length his teacher has, wondering if he should

feel embarrassed for his own fake *****.

"You're so beautiful." Saitama says absentmindedly, unknowingly clearing the insecurities in

Genos's head. Genos smiles up at his boyfriend, and Saitama freezes for a moment because of how

damn gorgeous Genos's smile is. He nearly looses himself in the smile, but comes back when he

hears a low whine from his student.

"S-Saitama... Mnn.." Genos moans quietly, his body feeling unbearably hot and he desperately

needed something to release the pressure that's been building inside of him. He doesn't understand it,

but Saitama does completely.

"Can't wait another moment right babe?" Saitama says, leaning down and peppering light kisses all

over Genos's face. Genos doesn't reply, only lifts his hips some to try and get his and his teachers

erections to rub together. Saitama shifts so that they don't touch, chuckling cruelly.

"Beg for me Genos. Beg for me to touch you."

Genos is shocked and thoroughly aroused by the dark and demanding voice his boyfriend has taken

on, loving the way he ordered him around. Submissive? The term comes to him, something he

researched earlier.

"P-Please Saitama... I-I need you to..." Genos shudders involuntarily, "I need you to touch me."

Saitama could *** from just hearing Genos beg. In a rush now, his erection growing almost painful,

Saitama makes Genos suck three of his fingers (which was so fucking hot) before lining one of them

near the entrance Genos has. He slowly slips one finger in, surprised when there was no resistance

and the inside was already sopping wet and soft.

"Y-You don't need to prep me sensei.." Genos informs him, self lubrication being apart of the new

modifications Dr. Stench gave him. Saitama licks his lips at the thought, and lines the head of his

now leaking cock to the pink entrance. Saitama looks deeply into Genos's eyes, who looks just as

intensely back and Saitama watches in awe and adoration as he pushes in- the way Genos's eyes

widen and mouth opens in pleasure- his entire body clenching and tensing from the foreign feeling.

Saitama doesn't stop until he's all the way in, then leans his head into Genos's shoulder- breathing

heavily.

"Are you okay love? I'm not hurting you am I?" Saitama asks Genos, his face masked in

uncharacteristic concern. Genos's heart (or whatever he could call it) swells at his masters words, the

way he seems truly concerned for his well being. Genos doesn't reply for a moment so Saitama

becomes worried,

"Oh my gosh I probably am I'll pull out-"

"NO!!" Genos suddenly shouts startling his sensei and honestly himself. He's never loud or

demanding with his teacher. Saitama's eyes are wide and he's half pulled from Genos who's faced

has turned an incredible pink because of his embarrassment. Saitama suddenly smirks, a devilish look

to his eyes and he begins to pull out again,

"N-No! Please Saitama don't pull out!" Genos cries, holding Saitama's arm where it was so he

couldn't back up anymore. Saitama pulls his bottom lip into his mouth with his teeth, trying to control

himself and not ravage the sexy boy in front of him. Genos realizes what he did again and begins to

stutter, not meeting Saitama's eyes as he explains poorly,

"I-I'm sorry it's j-just.. I don't want you to pull out.. You feel so good and I-I didn't expect it is all."

Genos explains, his face red and his eyes looking everywhere besides Saitama. Saitama feels himself

grow hornier just hearing such endearing words from his student, the way he's bashful even when he

literally has Saitama's **** in him in the most intimate way. Saitama once again tries to control

himself as he leans down and presses a soft but meaningful kiss to Genos's lips.

"Okay, tell me when you're ready."

"I'm ready." Genos replies quickly.

Saitama laughs against Genos's chest, his face pressed into it before he leans up and grabs Genos's

hips. Saitama shivers feeling Genos's insides clench around him, and he wonders if that's part of the

"modifications".

"Let me know if I hurt you Genos." Saitama demands seriously, not wanting to hurt to person he

cares about. Saitama always has to be on high alert when getting intimate with anyone, because of

his strength that could so easily hurt someone if he looses focus. Genos smiles and nods his head,

"Yes sensei, I will let you know. Though I doubt you could." He says sweetly. Saitama smiles

before suddenly slamming himself deeper inside, plunging into the wet hot heat. He groans loudly

from the amazing tightness Genos has and he looks up to see Genos's eyes have clenched shut and a

hand has been wrapped around his mouth. Saitama frowns at that, pulling Genos's hand from his

mouth and holding his wrist against the bed. Genos opens his mouth to protest but Saitama slams

back into him before he could say anything or close his mouth, so the pleasure filled orgasmic moan

that belts out of him goes unfiltered. Saitama's hips stutters at the unexpectedly sexy sound Genos let

out, and apparently Genos didn't expect it either because his eyes are wide is disbelief. Saitama

smirks, leaning down and pressing another kiss to the corner of Genos's lips.

"You sound beautiful, keep making those pretty sounds for me okay?"

Genos nearly melts at the kind words, and when his teacher suddenly slams back into him with a

force that has the bed knocking against the wall- another moan comes from him. He gasps for breath

as his boyfriend continued a steady rhythm, his teachers **** rubbing his inner walls in such a way

that has him seeing stars- the tip hitting his prostate occasionally making his toes curl in absolute

delight.

"Ah! Ah, Saitama-sensei!" Genos cries out, wrapping his arms around his lover. Saitama's lips are

right next to his ear when Saitama pants out,

"Say my name Genos, call my name while I **** you." his voice was different from normal, it was

low and rough and damn sexy. Genos shivers against Saitama before a particular ****** has him

crying out his boyfriends name- the word full of love and passion and pleasure. Saitama groans

against Genos's shoulder, biting down onto his collar bone as he drives himself into his lovely lover.

"F-**** Saitama." Genos pants out, his metallic fingers pressing into Saitama's shoulders. Saitama

gasps out when Genos clenches against him so tightly he almost came. Trying to regain some control

Saitama pulls away from Genos's bitten shoulder and slows his pace only slightly, so he could lean

up and watch the beautiful expressions cross Genos's face. Embarrassed by being watched Genos

turns his face, but Saitama still has a great view. Genos decides to do the same and take in every

detail of his lover that was currently pounding him into oblivion. The way Saitama's normally goofy

big eyes have turned dark and small- full of emotion and want. The way his normally care free

attitude was changed to this sexy, thoughtful, caring, intense person... Genos has never seen this side

of his teacher before, only small glimpses that has goofy reasons behind it being shown. But now it's

like...

"Gah!" Genos cries out when suddenly one of his switches was turned on, one he didn't know

about, and his body all instantly turns 10 degrees hotter. On top of that a desire, different from the

natural one he's experienced, one that feels almost insane takes over him. Saitama notices the drastic

change Genos takes, the once blissed out expression turning to one of intense desperation.

"Saitama! Please, **** me as hard as you can!" Genos begs fiercely, wrapping his arms around

Saitama and bringing him down to his face. Happy but confused by the sudden request Saitama

looks to Genos, but Genos only began whimpering- slamming hips against Saitama's ******.

"****..." Saitama groans, the pleasuring tingles becoming almost overwhelming. He mind was a

mess and his head was a fog, his lustful desires taking over him. But Genos wanted him to go all out

anyways so **** it.

"G-God, did your body get hotter or something?" Saitama asks, feeling like he's getting caught in a

fever of sex and Genos's body. Genos doesn't reply, just continues to desperately rock his hips

against Saitama's stilled hips- basically fucking himself against Saitama. Saitama's dark, hooded eyes

watch the scene, of the almost desperate Genos using Saitama's **** however he liked- taking what

he wanted from Saitama. Saitama growls and suddenly grabs Genos's hips, flipping him around so

that he was one his hands and knees with his *** facing Saitama head on.

"W-What are you doing?!" Genos asks, almost wanting to cry because Saitama's **** wasn't in him.

Genos doesn't know what it is but his honestly feels like he's going to fucking die if Saitama didn't

**** him. The switch apparently controlled his lust, or something, and now that Saitama switched it

on Genos doesn't presume it's going to turn off until the two of them ***.

"Shut up and let me make you feel good." Saitama demands, suddenly taking Genos's asscheeks and

spreading them so that his puckering and wet hole was in view. In a heartbeat Saitama has his tongue

pressed against the twitching hole, lapping around the outside before pushing it's way inside.

"Gah!! O-Oh lords!!" Genos gasps out, the immense pleasure almost hurting by how good it felt.

He's never felt like this before, he's never felt so human and alive and good and fucking wanted. He

felt craved, and damn it feels good to be craved and crave someone. Even better when the one he

craved does the same for him. To be able to share their mutal love. Genos withers and trembles in

Saitama's grip he has on his hip bones, so there was no escaping the blinding pleasure of Saitama's

long and slick tongue eating his insides, making his legs tremble and feel like jelly.

"S-Saitama! I'm going to ***, I don't want to *** without you!!" Genos gripped the sheets

desperately, pulling at the fabric for reasons unknown as he trembled and shook in the pleasurable

torture Saitama was giving him. Saitama pulls his tongue out at Genos's words, once again being

stirred up by the amazingly hot and innocent words Genos cried out. His voice that normally was so

stoic and measured, was now pleading and needy- needy for Saitama. Because of Saitama. It drives

him wild, makes him feel so crazy with possessiveness and love and wanting- the fact he changed

the person and the person only changed for him. He pulls out the sexiness and humanity from Genos,

and he loved Genos. So being able to share their love like this... Saitama was losing himself in the

high of sex, love, and Genos.

Saitama aligns himself with Genos's now glistening hole, not hesitating to ram himself inside. He

slipped in smoothly and glides deeply inside, pressing against Genos's prostate easily because of the

new position and new fluids. Genos nearly screams out Saitama's name when he pushed in, and

Saitama knew the neighbors were probably was hearing all over this- and if not they definitely heard

the lustful cry Genos just let out. But that only egged Saitama on all the more. Grabbing Genos's hips

once more and slamming the back while he drove himself forward, the slapping sound in the room

being louder then Saitama's pants and groans. Genos was a mess below him, a beautiful mess. Sweat

clinged to the both of them, Saitama mostly because of the immense heat Genos's body was

producing and also because of the vigorous thrusting he was doing. He feels Genos clench around

him and reaches forward, wrapping a hand around the silicon ***** Genos had- blocking his

******.

"Ah ****!" Genos cries out almost angrily, his desperation to *** getting the better of him. Saitama

grins at the curse word, Genos not being one to cuss very often- actually Saitama hasn't heard Genos

cuss at all expect for now and a little earlier. Cussing is such a... Human thing to do. Being able to

pull that out of Genos because he was fucking him that good- well.. Saitama was close to cumming.

He gives a few more ****** before beginning to release his grip on Genos's leaking **** and stroking

it instead- trying to bring their climaxes together.

"Ah ah ah... S-Saitama.. 'm close!" Genos moans/slurs out, lost in a blissful state of having his ***

pounded. Saitama groans, and gives one final hard stroke before Genos was coming unraveled all

over their bed. Saitama follows soon after, cumming deeply inside, digging his fingertips into

Genos's hips as he does so. Genos shivers feeling the hot *** release inside of him, and Saitama falls

onto the bed next to Genos- breathing heavily. They both lay and panted, before Genos smiles at the

ceiling.

"I love you Saitama-sensei." He says, not even looking at Saitama, more staring into a future Saitama

couldn't see. Saitama smiles, looking up and doing the same thing, truly analyzing the fact that yeah

he does love Genos.

"I love you, so much it's almost scary Genos." He answers, smiling at the ceiling just like Genos.

Genos turns his head so he could smile at his teachers/lovers/boyfriends own smiling face.

"Are we going to be together forever?"

"Until I'm old and grey."
