Author: SO! This was meant to be a One-Shot, but since I still got favorites even now...I thought why not add a little more? This is Part I, but don't worry there's fun to be had here ;) The second part is just...another part of the plan, fufufu.

Also, if you love the story (or if it just made you laugh), Please send a love note! Or a Review or put me on your will for all your yaoi goods...*cough*

Enjoy!

(did I mention a review? hahaha. ok, I'll stop. Please don't hit me with that - unless you're Sonic. Now, thaaat's an idea...)

Saitama wasn't used to this new life with Genos and Sonic. Ever since that night, he's been fighting monsters non-stop and hasn't been home in a week…

Even now, he blushed about what happened. "I can't believe I made those noises…!" Mortified, he held his face in his hands.

Whatever. Just another day. I'll just keep fighting monsters - oh, I don't see anymore?

He calls up HQ: "Hel - "

"Saitama! It's you! W-Wher - ah, I mean, DON'T HANG UP." The operator yelled. "You cleaned up all the monsters?!"

"Yes. I want to know if there were more-"

"Now the C rank heroes have no work for today! Please take a vacation! We'll PAY you!"

"W-"

"That is all." Click.

Saitama dropped his arm. Siiiigh. A vacation? They really cared about their workers. I guess. Maybe Genos would like to go to the beach -

Uh. His face heated up again when he thought about the blonde cyborg and his natural…prowess. Why? Why did he like an old man like me? He never understood the younger generations…

Just when he was about to go fishing for food (again), a familiar voice shrieked from behind.

"SAITAMA!"

"MASTER!"

Saitama froze. Oh god. How did they find him? Before he could get his thoughts together and run, two bodies crashed into him. "Oof."

The trio crashed to the ground and next thing he knew, Genos clung to his waist in front while Sonic held his shoulders from behind. They clasped to him hard. "W-Where did you run off to, Master? Did you hate it that much?"

Genos's eyes were empty as if he saw the end of the world itself and Saitama felt a prick in his heart. Out of habit, he automatically tried to placate him. He was always bad with that shot puppy look of his. "No, no. It wasn't that…I liked it really, I did, so don't cry…" Wait, what was he saying?!

Sonic suddenly bit him from behind and it bled a little. He winced. That was another reason why all this was just scary. Ever since he succumbed to pleasure that night, his body was especially sensitive. The fact that he could actually bleed now was terrifying as it was exciting. Good news, he tested this phenomenon on the monsters, and found out that when the fighting was over, he was still the same as ever - Invincible. It was just with these two that his body changed. Like when they had s-s-s…Oh god.

Saitama could feel his face burn even more as the memories of that night replayed in his head.

Sonic hissed into his ear angrily, "Never again. You'll never leave us again. Saitama."

Genos nodded in front, his teary gaze suddenly replaced by burning orbs of fire. "Master. I cannot live without you."

Sonic then chirped, "So we decided to take you on a vacation. Somewhere nice, relaxing…and isolated. Expect to not leave for a while. It's time to make up for lost time. You'll looooove the activities we have planned…" He licked his neck and Saitama barely suppressed a shiver as he tried to struggle - only to fall over his now weakened knees. So embarrassing! The men didn't even flinch as they still sandwiched him. Sonic just nibbled on his neck as he said, "I've learned a few new…massages….to help your aching muscles after all that hero work. Sai~ta~ma~"

Genos stood up, lifting everyone - before he threw Sonic off Saitama's back like a cat tossing her kitten away. He then hugged Saitama around his waist to himself. "I've arranged for transport."

Saitama could feel a certain bulge rubbing against his asshole and he stiffened.

Immediately a flying car of some sort flew out of the sky. A silver beauty that made Ferrarris look bad and when it landed, the door swung open. "The Doctor's special line of brand cars that only the extremely wealthy can afford- it fundsed his research, but he gave me my own. Chronicle line. Now we can go anywhere."

Sonic stuck his tongue out from the ground and jumped to his feet in one swift motion.

Genos scoffed when he saw that, "Show-off ninja."

"Blockhead of a robot."

"Small peni - "

"Can you let me down already?" Saitama cut him off as if none of this were a big deal…except he had a plan. See, he tested another thing while he ran away -er, focused on work. Whenever he got close to the two men (he made sure to use his real full speed so they couldn't have noticed him), it only took a few seconds to retain his "Superman Cheat" he now called it. So as soon as Genos let go of him, he could immediately run off to the other side of the world.

Perfect Plan! Hahaha! Saitama cheered himself on.

Only to get crushed by Genos's merciless answer,

"No."

Sonic peered at the bald hero from the side and smiled knowingly…appreciating Saitama's guilty face. "I'm sure it's never occurred to our dear hero to run away from us like a coward, but now that we know you are weak to our presence due to our intimate staus, who knows how long it would take you to be in full power once we let go of you? That won't do. So, Genos and I finally agreed on something and are getting along like you wished before…"

Genos nodded as he spoke. "We decided not to let go of you not even once for the next week during our vacation."

Saitama could only look at them blankly. Dumbfounded. They thought this through that much?! Creepy?! "Eh? Not even once?!"

"Mm-Hmm~" Sonic nuzzled his cheek to the hero's, purring like a satisfied kitten over his first rat hunt. "We'll be in constant contact~"

"Not even to - "

Genos cut in. "Eating, sleeping, letting out waste, and especially baths. Well, not that you need leave our side during this time. I made sure the HQ gave you a vacation."

"You called them?!" Saitama's eyes bulged as he tried not to think too hard about the last things Genos mentioned.

"I am Class S. I'll do anything for you, Master." His eyes burned into Saitama's as if daring him to look away. "Anything."

Sonic then had to put in, "Well. Not like you'll have the opportunity to run. What with our dicks plunging into you at all hours. Think of this as our love nest time!"

"WHAT!?"

"Time to go!"

And with that the hero was whisked away into paradise…

Four hours later.

Saitama could only gape at the sight. "I-I thought this was vacation? Where's the beach?"

In front of him was only a small cabin. Complete with fireplace, wood stove, and a king-sized bed with metal chains hanging off the side and a couple of good ol' blindfolds laid out on the silken sheets.

He could feel the intense gaze on his back, his body still wrapped around Genos who trapped him with a bear hug. "W-W-What-"

Genos's voice was lower than normal, in fact it held a tinge of predatory vibes. "Master. You left us for a week without notice. Without a trace. If it weren't for your call to the HQ and my preparedness, they wouldn't have tracked your location via GPS and sent me your location. Do you know what you put us through? No idea where you went, how you were, what you felt. Just gone."

Saitama felt a pang in his heart and said, "I'm sorr - " He moaned as he suddenly found himself on the bed, his butt in the air and Genos's warm hand pressed against the small of his back.

Why did they keep cutting him off?!

"Master. I'll give you the night of your life - and you'll never want to leave again. You are mine. Mine." He snatched at Saitama's tights and simply ripped them off - not caring that it was a one piece. Now bare, his ass hung out in the air and he could feel the cold breeze from the cabin window graze his unbelievably sensitive skin.

A sudden heat came over him and Saitama moaned, the soft silk of the sheets amplifying the sensations. Genos rubbed his fingers, strangely smooth and warm now, around his buttocks.

"Mm!?"

He even gave a lick down there and Saitama jolted. "Do-Don't…"

Genos gave a naughty, playful look from above, his tongue on his butt cheek as he said, "Nice view." Then he flicked his tongue and gave a sexy grin as if saying 'you can't stop me'. What happened to the obedient student from before? Who was this bad boy! Did he fail as a teacher? What kind of man was he?!

During Saitama's existential crisis, Sonic, the lithe ninja that he was, crawled smoothly across the bed. He hovered over Saitama's panting face with a cheshire grin leaning closer and closer….

To peck his nose cutely.

Saitama startled and felt relief. Guess Sonic was being nice to him? Maybe he could get Genos to stop -

Suddenly he couldnt' breathe as a wet tongue wrestled with his. Plunging his tongue in forcefully, Sonic tightly pulled at the back of Saitama's neck to deepen the kiss, lips mashing together in a hot mess sending tingles down his gut.

Slurping noises came out and Saitama could only lose himself to the deep kiss. He itched down there while Genos played with his ass, teasing him with soft strokes and nipping at his flesh playfully. The feeling got worse as a burning sensation ran down his spine and his spread apart legs manhandled by the cyborg's heated metal hands.

"Gh—! Please…I can't take anymore…" Saitama moaned pitifully as one side of him was mortified by the lewd noises and the other side just wanted something hard and hot to ram up him. His body still couldn't forget that night, it itched and heated up. The tickling sensations got worse and his face felt all flushed with excitement.

When did his body turn into this needy mess? It was only one night and he felt nothing all week when he avoided these two…But now that they're touching him all over, their masculine scent and electrifying eyes making their presence intolerable. They made him hot, pleasurable, weak…

He hadn't felt so vulnerable, so real in so long. And he was afraid he was starting to like it.

"Ahn." Saitama gave a particularly wet moan when his now stiffened member jerked across the silken sheet below him as Genos pressed his ass down onto the bed, massaging his buttocks - groping here and there - and making sure the hero's long legs were still spread wide open.

Genos groaned, "Master, you have a little more bounce to your bottom half now. It seems we can go even longer this time." He kneaded slowly but strongly as Saitama squirmed against the sheets. "Be a good boy, Master. I'm softening your flesh. You'll need to loosen your muscles for when we pound into you." He said it so matter-of-factly, those dirty words poured from his mouth with no shame.

Saitama alternated between embarrassement and arousal, his dick grew harder at his apprentice's words.

Meanwhile, Sonic shed his clothes and placed himself before Saitama's lips. He chuckled darkly before hoarsely whispering close to his ear, "We're going to have our way with you now, my - dear - hero~" His breath, hot puffs that tickled the hero's ear lobes and he had to bite his lips to keep from panting out.

Why did his body become so weak to pleasure? Was it really just about being his kryptonite…or was there something more?

Lost in a delicious red haze, all Saitama could make out was the free air grazing his bottom half, that reminded him that his ass was bare to the world under two laser hot gazes.

His latex suit all but gone and every touch, every scrape against a thread, every trail of hair that strewn across his shoulder, tantalized him. Bothered him in unmentionable ways to the point that it was all he could do from begging to make it stop. Everything felt on fire yet made him want more, more, more.

The world's strongest hero had officially fallen.

It was then that Sonic touched the tip of arched member inbetween Saitama's plump lips, the searing warmth of his mouth instinctively sucking the ninja in and Sonic clutched at the hero's head, moving back and forth.

"Nn, nn. Ahh…that's it, that's good. Very good indeed, Saitama dear." He swung his hips and rocked along with Saitama's bouncing head. "Thaaat's it…"

Meanwhile, Genos gave a jealous grunt and dug a finger into the hero's bottom lips. "Pay attention to me, Masterrr." Genos's eyes hazed as he slowly started to lose his reason, his blushing cheeks gave him a drunken look as he gazed at the fit hero. His idol. His mentor. His Master.

Locked between a villain and a hero without even able to use a bit of his godly strength, Saitama sighed in defeat.

I haven't tasted defeat in a long time…Oh no. What am I getting excited over?!

Oh god, oh god. He was going down dangerous waters. Why didn't he feel repulsed or angry right now? Was it because it was his precious disciple and some pitiful, persistent villain? Anti-villain? What was Sonic anyway…?

He yelped when two thick digits plunged into his bottom hole and Genos whispered in his ear, "I'm going to prepare you much, much more this time." He thrust his fingers in and out, breathing deeply above Saitama, as Saitama could only stare at the strangely entrancing sight.

"Nn! Not there, G-Genos. I-I-I can't…!" He immediately got up from Sonic's lap to push at Genos out of reflex only to be held back.

Two thin, yet hard as steel, arms wrapped from behind him. "We're not finished here. Dear." Sonic's voice lowered a pitch as he blew in the hero's ears.

"Wa - wah - Wait." Saitama could barely get a grip of himself as he almost came from that voice alone. Fuck.

Sonic gave a deep chuckle and simply pressed his lips to Saitama's, laying waste to his reason. His accurate fingers rubbed at his nipples and trailed down his abs, dancing and massaging in maddeningly erotic ways.

"Nn…"

Suddenly a big thing slid inbetween his ass and Saitama jolted. "Ah!"

Genos mumbled as he pushed himself in, trying to hold back from going like a dog. "You feel so hot, Master. It seems you've gotten used to my size…"

"Don't say such embarrasing thin - AH! Ah, Ah, AHhhhhhh!" He gave a heavy moan as the handsome cyborg swung in and out, twisting this way and that in a decent pace. As if jogging before a marathon, he kept at it, restraining himself. His dick making a mess of inside him. "Gen…Genos! What happ…to slow?! Ahh!"

"I'm sorry. I'm trying. It's taking all I can not to pound hard into you right now. You feel so hot and soft and it's sucking me in! Nn..! Master!"

"Genos! Ah, no, Ahhh!" Tears leaked from his eyes at the sudden waves of pleasure that hit hard. He was starting to feel a little numb.

Meanwhile Sonic had a wicked idea as he looked at the cyborg thrusting into the naked hero. "Genos. Let's commence to phase II."

Genos snapped his head up even lost in lust and grinned. "Good idea, mongrel."

"Fuck you. Up we go, dear~" Saitama was already lost to the world in pleasure when Sonic lifted his back up so he fell across the thrusting cyborg. Because of that movement, the angle got deeper and harder - "Ahhh! SO DEEP! GENOS, GENOS - "

"Dammit, I'm starting to feel jealous. Don't forget it's my turn next, bastard robot." Sonic glared maliciously at the fun the two were having. "Better not suddenly drop him."

"Just load the water, scum." Genos ignored Sonic and stood up from the bed, still bouncing Saitama off his dick as he wrapped his legs around his waist. "Good, Master. There. Just let yourself be felt by me." As if he could control every part of his body at will, Genos flawlessly walked toward the bathroom despite moving his dick up and down Saitama's ass vigorously.

Even Sonic had to do a double-take. "What kind of monster are you?"

"The big kind. Will you focus on the plan?"

Saitama's ears perked. "Y…You planned this far….AhnnnN!" He was starting to get weary as he couldn't take anymore pleasure.

Genos merely tightened his grip on the hero's ass, pressing him down hard on him, and smiled gently, "Shh…Don't worry, you'll feel even better in phase II."

"No….Ah, Ahhh…!"

Inside the room, a round bath that could fit five sat in the middle, dug into the ground and covered in blue marble tile. All sorts of lotions sat around the edge. Sonic set up the bath, ran the water….and brought a box out from the cupboards. All ready for action.

"Now…Time for Phase II."

Bathtime is calling.
