When He Slaps Your Butt

(That picture killed me XD)
Saitama
You went to the market to refill the fridge at your apartment, Saitama was there too, not because of sales either since it wasn't Saturday. "Master Saitama, it's (Y/n)." Saitama looked up from a can with a 'Huh' to see you walking with a shopping basket on your arm. "So it is. Hey, (Y/n)." You were too zoned out to hear him call your name, he repeated himself another time while walking up to you. "Hey." You gave a confused look, about to turn around before Saitama's hand left your butt after smacking it, softly but loudly." "I said 'hey' three times." You blushed and closed your lips after a yelp and as Saitama walked away, back towards Genos, making you give him playful narrow eyes as you tried your best not to make your butt rubbing noticeable. "Geez." "Master." "Yes Genos it was necessary. She's lucky I controlled my strength."
Genos
You stayed the night at with Genos, well you came over for dinner but ended up staying late and reading Saitama's manga until you fell asleep in room Genos stole from the next door people, meaning he made a hole in the wall to the bedroom since it was their spare. Genos and you were going to go grocery shopping but you still continued to sleep and he didn't know how to wake you. "Hey. Genos's girlfriend. Wake up." You didn't budge, you continued to keep your eyes shut and sleep, Saitama then looked back at the tv. "Welp. I tried." Genos placed his hand to his chin. "How else could I wake her up besides telling her to?" He looked over at Saitama after hearing his player die. "Just give her a tap on the butt and ask again." Genos looked back at you then did so, put instead of a tap, the back of his hand left a small red mark, it was a soft pop but still echoed, making you sit up in bed with a small yelp. "Genos?!" "My apologies. But it's time to wake up." You have a groan after he left the room and went towards the kitchen, you gave narrowed eyes and made your way to the bathroom while rubbing your butt, you saw Saitama's face was shocked with a smirk. "It was you huh?" "I said tap." After you went into the bathroom, Saitama turned to Genos with a grin while Genos gave a head tilt. "You touched the butt Genos. How was it?" "Well. This was unexpected than the first time Master." "Huh?!"
Mumen Rider
It was in the evening when you got off of work, usually it would of been late but, you managed to get time off. You were on your way back to the apartment, you texted Mumen, he didn't reply so you figured he was busy. But he wasn't, he gave Saitama a ride and happened to being heading your direction, he smiled seeing you, he then gave a small chuckle and continued to petal just for him to extend his hand, you gave a small yelp after Mumen gave you a soft pop on the butt when riding past you, then stopped and looked at you with a smirk "Hop on." You blushed with a small giggle, walking over to him and getting on his bike pegs and held him tightly under the arms. He chuckled and rode off as you pecked his cheek. "You could of just slowed down and say 'hey'." "True but. Thought you might like that way more." You hit his shoulder, making him chuckle and you blushed deeply.
Zombieman
You were walking the streets of City C with Zombieman, you and him just went out to eat and to see if Metal Bat had any reports since he was in that city at the time. As the two of you stopped at the walkway to cross the street, Zombieman's phone went off, causing him to peck your head and walk away. "Hey there." You lifted up your head to see a young guy smirking at you. "Need help crossing the street gorgeous?" You blushed but gave parted lips and looked away, just as you did, Zombieman came up behind you, after seeing your pink cheeks, and gave you a slap on the butt before pulling you close by the waist. "Is there a problem?" The guy looked away with a head shake then winked. "I guess that's your property?" He walked away, you looked up at Zombieman, whose hand was still on your waist, as he looked at the passing cars. "Really?" "Well. You are mine." You giggled as he pecked your head and took your hand with a smirk.
Metal Bat
You were doing dishes when Metal Bat came into your house, he looked beaten up, you gave parted lips jut for him to walk up to you. "I'm fine don't worry." You smiled with a small head nod, he kissed your cheek before walking past you giving you a side ways tap on your butt with his bat. "Hey." "Don't hit me with your bat." He smirked and gave a laugh, then backed up as you looked back over at the sink, he walked back again but popped your butt with his hand. "There? That better?" You blushed and gave a small laugh, he placed his bat on the counter then opened up the icebox with a chuckle. You wrapped your arms around him and kissed his back. "Uh huh." He turned to face you, hugging you with a soda in his hand, closing icebox then placed a hand on your butt once more. You then hit his chest, making him laugh and walk away. "Lucky I don't hit you with a bat.." "Hm?" "Nothing. Love you."
Blue Fire
"Hey you." You gave a small hug towards Tornado, you stopped by at the Association to see her and to go out for lunch, you did plan on going to see Blue Fire but you had no idea where he was at the time. As you and her talked, the elevator door opened to reveal him, he gave a confused look seeing you there then gave a head shake and walked up behind you. Before you could speak, a soft but yet lightly echoing pop from your butt cut you off.
You gave widened eyes and bright pink cheeks at as he walked by, Tornado has gasped lips, Blue Fire kept walking, he then stopped and turned his head just a bit, you saw a smirk on the corner of his cheek before he continued to walk away. "Wow. Didn't realize he was the kinda guy?" You smiled and rubbed the bottom of your butt. "You have no idea."
Stinger
You were sitting on the couch with Stinger, the both of you making small talk while cuddling before there was a knock at the door. "Oh. Hey." You gave a small smile towards Lighting Max, he gave a small nod and requested for Stinger, you were about to call Stinger's name so the three of you could go to the city as planned before he came up behind you with a smirk towards Max. You yelped after he popped your butt. you then placed your hand to it and rubbed softly as he stood next to Max after walking past you. "That hurt!"
"They call me Stinger for a reason." You narrowed your eyes, Max gave sealed lips as Stinger chuckled, seconds later he made 'ow' sound after you punched his arm with a smirk after walking down the steps, then pushed past the two of them as the looked at each other.
Sweet Mask
You and Amai were both on your way to a restaurant, on business, but also on a date, he wanted to treat you to a night so he decided to bring you to the new eatery in city A. While walking, a group of reporters came out of no where, taking pictures and asking questions. "Amai, are you with this women?" You gave an eye roll, Amai just chuckled and pushed his blue hair back. "Yes. This is my beautiful girlfriend." Sweet Mask then gave you a soft pop on the butt before pulling you closer to him, smirking as you gave parted lips and light pink cheeks, after that he took your hand and pulled you into the restaurant, leaving you still flustered that he did so.
Sonic
While walking with Puri, Sonic saw you talking with your friend (F/n), the two of you just finished having lunch together. Sonic smirked seeing you bend one knee to where the half side of your butt went up (you know that standing position girls do while waiting  with crossed arms XD) "Aren't you going to give her a pop on her behind" Sonic raised an eyebrow with a confused look. "Just do it. She'll love it." Sonic then gave an eye roll after Puri gave him a small nudge on the shoulder. He then sighed, as you gave a small nod, Sonic gave you a soft slap on the butt, you turn with light pink cheeks and narrowed eyes, Sonic's eyes widened as he took a step back, you then smiled and blushed with a small giggle and waved off your friend, then raised an eyebrow towards him. "Sonic? What's on your mind?" You giggled, making him 'Tch' with a eye roll before waking away, just for Puri to wink at you.
Flashy Flash
"(Y/n)!" You and both Flashy turned to see Tornado hovering over to the both of you with her arms crossed and narrowed eyes, you gave a confused look at her when she planted her feet on the ground and smiled when she looked over at Flashy. "Hope you don't mind that I steal your girlfriend." He didn't have a smile, just a straight face, Tornado knew he smiled, he couldn't help it when he was around you but, he knew that he didn't want you to go. "Okay." When you stood up from the desk, about to walk away, Flashy gave you a soft pop on the butt, making you look to him and Tornado widen her eyes. "Love you." You blushed with a smile after looking down, Tornado grabbed your hand and pulled you to the door as she rambled.
Garou
It was your day off, Garou was still asleep in your room since he stayed over, you have just gotten out of bed planning on taking a shower because you were freezing. You stripped out of your pants, you heard your phone go off minutes later, you rushed to get it, it was your dad. After getting off the phone with him, Garou was up smirking seeing you stand in your undergarments as you stood in the bathroom, you gave a small sigh and when you did, it then turned into a yelp after Garou gave you a loud pop on the butt. "Sexy." "Ow! Garou?!" Garou chuckled and continued to walk down the hall, you held your butt and rubbed it with narrowed eyes, you wanted to smirk but if you did he'll probably to do again. You locked the bathroom door, you heard him laughing and that made you laugh, but when you checked your bottom, your right cheek was red. "Garou you're an asshole!" "Yep. Love you." "Uh huh..love you too."
