First Time

(I died laughing. Don't know why but I just did XD gotta luv Mumen.) Saitama
"You're cheating!" You sat up on your knees next to Saitama as you played a video game with him, he just shrugged as he laid on his mattress. "Not my fault you suck." You narrowed your eyes and looked at him, he looked at you then glanced down then back at the tv. "Didn't know you had my hoodie. I was looking for that." You gave an eye roll then looked around and got up. "Where's Genos?" "At the Heroes Association. Why?" You gave a shoulder shrug before you stretched and sat behind him on the mattress and looked into the back of his head at your reflection. "Staring at my head?" "Maybe." "Seeing how pretty you are?" You blushed then hit his shoulder with red cheeks. "Shut up." He paused the game and looked at you. "Last time I try to be nice." You smiled and gave an eye roll then pressed your lips to his, he kissed back then placed down the remote control and put his hand on yours. Your eyes slightly widened seeing how much he was kissing back then you pulled away. "Sorry." He rolled back on his side then picked up his game control before you took it away. "Hm?" You glanced away then down with sealed lips before looking up at him. "Saitama." "I know. And I'm ready if you are." Your eyes slightly widened as he stared at you, you felt your cheeks heat up then you look down with a smile. "I am." He gave a nod then took your hand and put it around him and pressed his lips yours. You woke up to the sound of knocking at the door, you glanced down to see Saitama laying on you with his arms underneath you and him snoring with his face on the upper part of your chest. "Master Saitama." "Saitama. Get up Genos is back." Saitama groaned as you shrugged his shoulders and mumbled. "Okay." "Really?! Genos can you wait a second!?" "As you request Miss (Y/n)." Saitama chuckled as you gave narrowed eyes to him. "Poor Genos."
Genos
Surprisingly Dr. Katsuno let you off of work early. You gave a sigh seeing that Genos didn't need a repair to say but you were able to finish up a project you've been working on for weeks. Once you stepped inside your apartment you immediately went to go change. "(Y/n)." You smiled and went to the door still putting on a shirt to see Genos there. "Hey you." He gave an nod then kissed your hand before stepping inside. "What brings you here?" "Well for one. I haven't seen you at all today. And reason number two is that. I must discuss something with you." You smiled with a confused face expression then gave a nod. "What is it?" He gave you a nod once you laid on the couch staring up at him as he shut the door then looked at you. "After talking with Saitama and after visiting Dr. Katsuno. I think now it's the appropriate times to discuss." You gave a smile then stood up off the couch. "Twenty words or less Genos, what is it?" "It'd be an honor if you were my first." Your eyes widened as you took a step back with parted lips, he stared at you until you glanced back up at him. "But Genos." "You have to trust me on this (Y/n)." You gave a small nod then gave a smile after he cupped your cheek. "Okay." You pecked his lips, he then pulled you close to him and kissed you deeply until your hands went around his neck. Your (e/c) eyes fluttered open to see Genos laying next to you, you gave a small smile seeing his eyes were shut. You covered yourself more in blankets once you rolled to the side with Geno's arm still around you, you pushed back his blonde hair. You smiled seeing him still asleep, you closed your eyes and did the same with a chuckle under your breath. "I have a feeling Saitama is going to hear about this..."
Mumen Rider
You gave a small smile with a nod as you walked beside Mumen as he pushed his bike up the stairs of your apartment and into the room. "That's my day for ya." He gave chuckle and took off his helmet, but keeping his shades on as he sat on the couch and took of his shoes. You approached him and gave a smile, he looked up at you and took your hand, kissing it. "Yes Beauty?" You pressed your lips to him, he tensed then relaxed and kissed back, you sat on his lap and placed your hands to his cheek as his arms went around you, when he pulled back with light pink cheeks, he looked away. "Mumen, I'm ready if you are?" He looked back at you, pushing your hair to the side with a calm smile and nod, he stood up and followed you to your room, once the two of you entered it, you wrapped your arms around his neck, kissing him deeply once more as his hands rested on your waist. A couple of hours later you woke up on Mumen, you smiled and rubbed his bare and toned chest your hand was on, just for him to rub your lower back. You looked up to see him with his eyes shut and a calm smile, you gave a small giggle and kissed his cheek. "I love you." "And I love you." He pulled you closer to him, making you smile and him do the same.
Zombieman
You gave a small smile as you told your day to Zombieman after you asked as the two of you stepped into your apartment, after he took of his shoes and rested his axes in the same spot while you went to your room to change, when you pulled off your shirt, trying to cover, you stopped speaking and turned to see if Zombieman was still listening, he was but he was standing in the doorway, leaning against with the frame with the edges of his lips curled. "Hm?" He double blinked and went up to you, making you tense and bring the shirt up more. "Nothing, you're beautiful." You blushed and looked away, he then lifted up your chin and pecked your lips, looking away soon after, you cupped his cheek and that made him look towards you, you gave a small and nervous sigh. "I'm ready if you are.." Zombieman gave a small smirk, holding onto your bare sides and kissing you deeply. "I am." A couple of hours later, you laid in Zombieman's arms, half asleep, he held you close to him, tightening his grip around you after you kissed his chest. "I love you." "I love you. I always will." You smiled with a small hint of blush as he pull you closer to him, giving you a long kiss on your forehead before resting his chin on it.
Metal Bat
   After you walked up the stairs of your apartment with Metal Bat following behind you, listening to you talk about work after he asked, you stoped speaking once you stepped inside. "Why'd you stop?" You placed your keys on the counter and faced him as he raised an eyebrow at you, laying his bat against the wall. "Didn't think you were listening." "Well I was." "Uh huh." He then pulled you close to him and walked with you backwards towards your couch. "Well, I'm not lying." Metal Bat sat on the couch staring up at you as you sat in his lap facing him, making you blush and glance to the side with a small smile, he then kissed your chin, making you look at him and kiss your lips. "I love you." "And I love you." Your lips connected with his once more, his lips moved against yours as you placed your hands on his shoulder, you felt the tip of his tongue and pulled back, making him smirk and press his forehead to yours when you looked down. "I'm ready if you are." You blushed and cupped his cheeks, giving a head nod before he released you and followed you to your room, kissing you once more after the door shut. You laid halfway on Metal Bat when your eyes fluttered open hours later, you smiled feeling him stroke your (h/c) hair, making you hug him tighter. "Baby." You lifted up your head and looked at him, he was smirking with his  eyes shut as his hand began to rub your back. "Hm?" "I love you." You blushed with a smile and laid back on him as he smirked more. "I love you too."
Blue Fire
Blue Fire walked you home since it was late, he walked with his arms crossed and eyes shut as you twirled your keys with a small laugh, telling him about your day. When you unlocked your apartment door, you held the edge of it with a calm smile as Blue Fire stood outside. "Well..thanks for walking me ho-." Your eyes widened after Blue Fire told your hands and pressed his lips against yours deeply, you placed your arms around his neck as he placed his hands on your waist, when you pulled back, your forehead was pressed against his. "(Y/n). Words can't describe my feelings towards you." You blushed deeper, when you looked up, Blue Fire did the same. "Blue Fir-." "Be my fir-." After he cut you off, you cut him off with a small peck and a head nod and a smile. He then lifted up your chin and pulled you to his lips, both of you shutting your eyes in the process. Hours later, your (e/c) eyes fluttered open just to see Blue Fire's eyes shut as he laid on you underneath the sheets, his head above your chest as his arms were wrapped around you.

"I love you too."

You and Stinger made small talk as the two of you were on the way back to your house after you got off of work, it was late so he joined you on the walk home, his arm was locked with yours as you both smiled. "I love you." You blushed and looked to the side, making Stinger step in front of you and walk backwards as he held your hands. "I love you too." He pecked your forehead before glancing to the side after hitting the stair case of your house, when he looked back, your lips connected with his. He kissed you deeply, you did the same back before he pulled back. "Be my first." You gave parted lips and light pink cheeks after he whispered, he gave a small smile before glancing away.
