It all start when Hiyo asked.
"Oniichan? Why do you have gauze tape on your feet?" Hiyo asked noticing Yokozawa walking practically barefoot around the house.
Yokozawa glanced down before saying "Oh, my feet are still a little beat up after I went to the gym yesterday."
Kirishima looked up from editing his manuscript curious, in all the months of dating Yokozawa, he never mentions he did any form of exercise or that he went to a gym. Granted, he didn't really know what Yokozawa did in his spare time as a hobby or for leisure, and it wouldn't hurt to pry.
"Since when do you go to the gym?" Kirishima asked before mentally slapping himself at how that sound. He noticed how Yokozawa had to refrain from glaring at him in Hiyo's presence.
"I go to the gym four times a week," Yokozawa said his tone changing slightly.
Damn, he should really apologize or try to recover before his sex privileges are taken away. But as always when it comes to Yokozawa, his brain and mouth are working on two separate plains.
"You don't look like it," Kirishima let slip, realizing his mistake immediately. He notices the unhappy eye twitch Yokozawa gives him with a straight face.
"Not everyone who goes to the gym can look as sculpted as you Kirishima-san," Yokozawa replied before going into the kitchen.
"Papa! You tease too much, I think you hurt Oniichan feelings," Hiyo reprimanded him.
"I think so too," Kirishima said watching Yokozawa out of the corner of his eye.
After that conversation, Yokozawa didn't speak to Kirishima for three straight days unless it was about work. On the fourth day, after putting Hiyo to bed a bit early, Kirishima drove to Yokozawa's apartment and rang the doorbell. And to his surprise, Takano opened Yokozawa's door but he hadn't noticed him yet.
"Don't you dare get up!" Takano said pointedly to someone behind him, most likely Yokozawa "You need to stay off your feet for a while."
Takano then turned to face a stone-faced Kirishima. "Kirishima-san? What are you doing here?"
"I came to check on Yokozawa," Kirishima said smoothly. "Is he home?"
Takano looked like he was about to say something when a familiar voice said tiredly. "Masamune? Who is it?"
"Nobody important," Takano said blocking the door "Didn't I tell you to lay down, you're going to collapse at this rate."
"…going," Yokozawa said retreating.
Takano then turned back to Kirishima. "He needs rest right now, I suggest you talk to him tomorrow." And with that, he closed the door on Kirishima's face. Kirishima was usually a laid back person in most situations but whenever it came to Takano and Yokozawa, he'd be lying if he said he wasn't jealous. He had to calm himself down before he did anything irrational, he just had to talk to Yokozawa tomorrow…
"Why were you with Takano last night!?" Kirishima exclaimed catching Yokozawa off guard as he was drinking his coffee. Kirishima stopped and waited, watching as Yokozawa tried to compose himself before giving him an impressive glare.
"So, you did come to my apartment last night," Yokozawa said glaring at Kirishima.
"I was…I wanted to apologize," Kirishima sighed before giving Yokozawa a cold look "But then Takano answered the door."
Yokozawa breathed through his nose before saying "I went to the gym yesterday and pushed my body to its limits, I ended up straining my back muscles and Takano came over to help. I didn't call him on purpose."
Kirishima pouted. "You could have called me…"
Yokozawa didn't answer him but just raised an eyebrow staring at him. The pair was quiet for a few moments before Kirishima asked. "Is it too much to ask to come with you?"
"Eh?" Yokozawa questioned "You're not serious…are you?"
"What?" Kirishima asked.
"You wouldn't last a second at the gym I go to," Yokozawa said bluntly.
Kirishima's eyes narrowed. "Wanna make a bet?"
Yokozawa raised an eyebrow before giving Kirishima one of his rare smirks. "What kind?"
"If I can last an hour with you at the gym, you must do whatever I want in the bedroom for a week," Kirishima stated.
Yokozawa thought about for a moment. "Let's raises the stakes a little, you last two hours with me at the gym and I do whatever you want for two weeks. But if I win you are not allowed to touch me for two weeks. Do we have a deal?"
"Deal," Kirishima said before he felt uneasy at the smug expression Yokozawa was giving him.
"Meet me at my place by nine thirty tomorrow," Yokozawa said walking back to his floor "you're lucky it's the weekend otherwise, I would have had you up at four thirty in the morning."
Kirishima suddenly got the feeling that he may have dug his own grave.
The next morning Kirishima dress in casual workout attire before driving to Yokozawa's apartment complex to find him waiting for him on the sidewalk. Kirishima tried not to stare at Yokozawa's workout attire, Yokozawa was in a black tank top and black sweatpants that shaped his lean figure, he also had on black sneakers and a backpack slung over his shoulder.
"Good, you're on time," Yokozawa said, "Here's the address, hopefully, we can get parking."
Kirishima had a sinking feeling that he was about to have his ass handed to him but keep his cocky carefree attitude on. The drive was silent with the occasional direction from Yokozawa, soon Kirishima was following Yokozawa on the street before Yokozawa held open an unmarked gray door for Kirishima.
"Come on then, we don't have all day," Yokozawa said.
Kirishima walked in only for his jaw to drop, he now understood why Yokozawa was smug back at the office. The gym Yokozawa worked out at was an aerial circus gym, for people who trained to be in the circus. Kirishima looked around and saw body contortionists bending like they had no bones, women on silks doing flawless routines and teenagers doing advanced gymnastics on high bars.
"Close your mouth Kirishima-san," Yokozawa teased "You'll catch flies that way."
Kirishima snapped out of his shock just as a woman walked over to them on her hands with her leg practically folded into her back.
"Hey Takafumi," A familiar voice said.
"Aikawa?" Yokozawa questioned.
Kirishima then recognized her as she straightens herself up, she was Usami-san's editor. Soon the pair started chatting forgetting that Kirishima was even there before Aikawa turned to him and said "Well, have fun. Yokozawa's regimen puts some of the instructors to shame."
Kirishima chuckled nervously as she left, Yokozawa, on the other hand, nudged his shoulder and head out chalk powder and gauze tape.
"I don't want your skin peeling off by the end of this," Yokozawa said before slipping off his sneakers.
Kirishima gulped. "Go easy on me, will you?"
Yokozawa raised an eyebrow before giving Kirishima a smirk that sent chills down his spine. "Try and keep up old man."
In the end, Kirishima last only forty-five minutes before he called it quits and ended up watching Yokozawa bend, flex and perform tricks he never thought he'd see in his lifetime. At one point Yokozawa was in a full split on the aerial silk and Kirishima could help but to wonder if he'll ever see that in the bedroom. Currently, they were back at Kirishima's apartment, Yokozawa was taking care of an extremely sore Kirishima.
"Do you need an ice pack for your crotch?" Yokozawa asked as he placed two ice pack under Kirishima's knees as Kirishima nearly took off the skin off them attempting to spin around the high bar.
"Yes please," Kirishima groaned. His back and hips were killing him, he was lucky enough that Yokozawa placed his bruised feet in a large basin of warm water to relax them.
"Well looks like I won," Yokozawa said but there was no smugness to it.
"Yokozawa, I have a question," Kirishima said looking over to him "You do that for leisure?"
"Yes, I used to do competitive gymnastics until I was eighteen before I quit," Yokozawa said his cheeks starting to gain a pink hue "But I still like training and the exercise so I just stopped being competitive and did it for fun."
"You really are amazing Takafumi," Kirishima said watching as Yokozawa blush darken "I'm so lucky to have you."
"S-says the guy who could keep up with me on the bar," Yokozawa said looking away from Kirishima "A-and the deals still on you know, you can't touch me for two weeks."
Kirishima smiled to himself seeing Yokozawa's embarrassment not caring at all about the bet. "I love you."
"D-don't be an idiot!" Yokozawa snapped but the blush on face said otherwise.
