Hello! This is my very first fan fic, so I hope it's decent enough! I'd love any pointers and advice. Thanks for reading, enjoy!

*I own nothing*

I watched as Saitama lounged on the futon, picking at his ear. I was hesitant to approach him and let him know dinner was ready. He seems to be particularly moody, especially these past few days. I've scanned him many times, yet no detection of any illness or imbalance. His heartbeat is slightly elevated, but it didn't seem to be of issue. I looked at him, confused as to how I could have upset my Sensei. Maybe I could just ask for his forgiveness and put an end to it. Maybe if he knew how much he really meant to me, he wouldn't be so upset towards me. I'm not exactly sure of what happened between us that led to this point. I understand my devotion can become overbearing for my master, but I just need him to know how much I care for him. Whatever it is, I wish to move past it as soon as possible. I don't enjoy receiving his cold shoulder.

~Saitama

'Ugh, fuck. He's watching me again', I thought to myself. I tried to act casual, picking at my ear and staring at the anime on tv. I felt bad at lashing out at him earlier. He really didn't even do anything wrong. I honestly hate thinking about it. The whole thing started when I had that strange, strange dream. I hadn't dreamt in years, so for the first after so long to be something so… lewd, was a bit unsettling. I remember hearing a gasp, followed by moaning. I could feel hands on my chest, I could feel someone.. Riding me. When I finally realized it was Genos, I had woken up, shooting straight out of bed and panting heavily. Genos continued to sleep next to me on his own futon, a soft whirring sound coming from his body. I wiped some sweat from my forehead and gulped, trying to get rid of the dryness in my throat. My panic only increased when I noticed my erection. I remember feeling guilty and ashamed when I saw it. Was it possible I was turned on by such an inappropriate dream? No, definitely not. I mean, everyone's bodies act strange sometimes, right? Anyway, since that dream a few days ago, I can't even look the kid in the eye. How could I? I'm his Sensei. Someone he respects and trusts. There's no way I could confront him. The worst of it all, every time I actually manage to look at him, I'm immediately reminded of the dream. I imagine hearing his moans, feeling his hands sliding down my chest as he sits up and glides back down over my... SEE! I'm doing it again! I can't keep this up. So for now, I avoid him. And, for some weird reason, my heart hurts because of it. I can see a pout on his usually stoic face. Usually I wouldn't care if I had hurt his feelings. But lately.. I can't help it. Obviously, something is wrong with me. I just need to figure out what.

~Genos

"Sensei! Dinner is ready. I have made udon noodles for you. I know how much you enjoy them." I announced. Hopefully some good food can resolve this. Master takes food very seriously, surely a good meal would help him forgive me of whatever I've done. "Uh.. yeah, okay" He yells back to me, rearranging the living room so that we may sit down to eat. I bring the bowls over to the table, and place his in front of him. He won't even look at me. I feel.. what, low on energy? No, that isn't it. I've scanned myself and I'm in perfect condition. So why is it I feel this way? I just feel drained, perhaps empty. I take note to see Dr. Kuseno after dinner. I sit myself opposite to Saitama and begin eating. I watch him slurp up his noodles. Surely he's enjoying them, yet he won't look in my direction. I can't take it anymore. Whatever I did, Master is surely acting childish in response. "Sensei.." I speak to him across the table. He keeps his eyes glued to the show on the television. There's that pain again. I see his hand resting on the table and decide to make a bold move. I reached out for his hand, grabbing it gently, yet firmly so that he knows how serious I am. "Saitama." I stated bluntly. As he finally turned to look at me, the expression on his face is one I had yet to see. Surprised and... is he blushing? I better scan him for a fever.

~Saitama

My body shivered the moment I felt Genos' hand on mine, I swallowed hard, forced to look at him. I could feel my face was warm, I must look like a fool. The look on his face let me know that I wasn't going to be able to avoid this. His hand felt.. comforting? No, that's ridiculous. And did he say Saitama? That alone made my heart pound. I looked at him for a moment. He was truly a perfect being. My eyes wondered down to his lips. Before I knew it, I was licking my own, wondering what his pretty mouth tasted like. 'Damn it, Saitama, keep yourself together!' I scolded myself. Finally I removed my hand from his, a little embarrassed I kept it there for so long. "Uh, yeah, Genos?" I asked him, trying my best to be nonchalant. I adjusted myself, attempting to ignore my growing erection. There was no reason for me to be acting like this. So what the hell was wrong with me? "Master, I know something is troubling you. You haven't been yourself lately, and I'm beginning to worry. If I have done something wrong to upset you, please forgive me. It is never my intention to be a nuisance-" I cut Genos off right there. Did the poor kid really think I was mad at him? Am I really that much of a piece of shit to not notice before? "Genos, please..' I responded. "You did nothing wrong. You're absolutely right, I haven't been myself. But it isn't your fault"...'other than the fact you're so damn attractive' I said to myself. "To be honest, I think I'm coming down with something. I'm having a lot of strange symptoms. I haven't been sick since I started training, so I'm just not sure how to deal with it, that all." Really, I wasn't lying to him. "Is that your reason for giving me the cold shoulder?" Genos said with a pout. 'This fucking kid... he's gonna be the death of me' I thought. "And for the record', he added, "I have scanned you plenty of times. Your body appears to be in perfect condition". "Genos, first off, please stop scanning me. Secondly, yeah, like I said, I'm just feeling a little under the weather and didn't know how to deal with it. Don't take it so personally." I replied a bit too harshly.

~Genos

'Don't take it so personally' he says? Does he not understand that he is my world? My motivation to become a better person every day? I feel the emptiness settle again, reminding me I needed to see the Dr. Which gave me an idea. "Sensei,' I announced, "I am going to visit Dr. Kuseno after dinner, as I need him to check a few things for me. Perhaps you would like to come along and let him have a look at you, seeing as he's accustomed to treating people like yourself." Surely he would accept this offer, if he truly felt sick. "Well, yeah. I guess it wouldn't hurt to have him check me out. Plus it would give me a chance to finally meet the dude" Saitama responded. We quickly finished our meal and prepared to go visit Kuseno's office. I'm thankful he agreed to go. I would never forgive myself if Saitama became ill under my watch. My master quickly changed shirts before heading out the door. It was nearly impossible to not stare at his perfect physique. I imagined what his abs would look like with bite marks all over them. My train of thought was cut off when Saitama cleared his throat, standing there, waiting for me. I must be coming down with a virus as well with such lewd thoughts crossing my mind. "Please, follow me Sensei" I offered. And with that, we began on our way. The weather was cool, since it was nearly winter. I saw my Sensei shiver a little. He's never enjoyed cold weather. As I walked closer to him, I offered my arm. "Please, Sensei, take my arm. If you're feeling sickly, it wouldn't be wise to expose yourself to the cold." I stated. Though, if I was being honest with myself, his health wasn't my only reason for wanting him so close. He hesitated at first, then nodded slightly. Avoiding eye contact, he locked his arm with mine. I pulled him a bit closer and heated myself up. It was easy to be warmer with him so close, touching me. Clearly, a cyborg like myself couldn't get a fever. I'll be sure to mention this is Kuseno. I felt a tingle run through my circuits when I swore I felt him lean into me. I don't believe I could blush, but if I can, this would be the time. My wires were practically pulsating. Glancing over at Saitama, he was an image of pure beauty. Little puffs of air escaped his parted lips. Suddenly, all of the sparks running through my wires rushed down to my crotch. I had never been so thankful for the metal plate I had there, covering my erection. Though it was a bit uncomfortable.

~Saitama

I couldn't help but lean into Genos' warmth. His body felt amazing so close to mine, I wanted to push myself right up against him. But clearly, that wasn't going to happen. It's a good thing we were already on our way to see the doctor, because this was getting out of hand. I peeked over at Genos. Was he.. blushing? I never knew cyborgs could blush. Maybe it's just from warming himself up for me. Though he did say he wanted to see the doctor for his own reasons. Perhaps he was getting sick too. The thought of Genos not feeling well made me sad. Why, I'm not so sure. Was it really so wrong for a Master to worry for his disciple? Surely not. I couldn't help but to think of how lucky I was to have such an amazing person want to stay with me. There hasn't been a single person to want to stick with me, the caped baldy. I took this opportunity to nuzzle my head against his neck. I mean, I can always blame it on wanting to stay warm, right? My eyes closed at some point. It was so relaxing to be like this. To be so close after days of avoiding him. I never want to do that again. Our pace slowed, almost as if we were a couple taking a leisurely stroll. This was so nice. I snapped out of my little fantasy when we came to a stop. My eyes opened and I lifted my head up, though I didn't make an attempt to move my arm away from Genos'. He didn't try to move his either, which was comforting. "Sensei, we're here" Genos spoke softly into my ear. My whole body shuttered. Who the hell did he think he was, making a move like that? I snapped out of my trance and retreated away from him, clearing my throat. "Right, thanks." I stated. The look in his eyes.. he looked hurt. I tried my best to ignore him. I waited for him to walk up to the door and let us in. 'Please' I thought to myself, 'this doctor better know what he's doing". And with that, I followed Genos inside.
