Dazai had been eyeing Chuuya's motorcycle since the day he got it. Trust Chuuya to spend his money on something so extravagant. It even matched his outfits, with its dark pink color. But Dazai couldn't completely make fun of him for it, not when it gave him ideas.
"I want to fuck you over that motorbike," Dazai told him.
"I'd like to see you try," Chuuya said. "I'm serious. I have to use my Ability to keep that thing balanced half the time, and with you there I can't. So I wanna see how you'll make this happen."
"Trust me, I will," Dazai said. He was good at making things happen.
He suspected the only reason Chuuya agreed to this at all was because he thought Dazai would fail, which only made Dazai more determined to pull this off.
As soon as they reached the alleyway where Chuuya had parked his bike, Dazai grabbed Chuuya and shoved him onto the seat, backwards, kissing him roughly as he did. Chuuya's hat slid off his head.
“We’re doing this here?” Chuuya asked, pulling back.
“Scared of getting caught?” Dazai challenged.
“I didn’t know you were an exhibitionist, Dazai,” Chuuya said.
Dazai pressed his lips to Chuuya’s again, tired of talking.
The motorbike, despite having its kickstand down, tottered dangerously. Chuuya pushed him back before he could force his tongue in Chuuya's mouth, and Dazai saw that his lips were very red from the force of the kiss. He tried again, and was pushed back.
"You don't wanna make out with me while trying to balance this thing. Unless...you're trying to be tender? Is this actually making love?" His lips curled, and even though it was a joke, they both knew that the last thing Dazai wanted was to make it seem like actual feelings were attached.
"Chuuya is awfully mouthy today," Dazai said.
"But I'm right."
Dazai placed his hand on Chuuya's chest and shoved him back, and Chuuya's head nearly hit the handlebars. Then he swung his own leg over the bike so that he was straddling it. His position felt precarious, and he wondered if he should have stayed leaning against the bike. But then he wouldn’t be able to do what he wanted, and Chuuya probably wouldn’t count it as proper motorcycle sex. He pulled Chuuya's legs up to balance on his shoulders. The whole time, Chuuya watched him with a half-smirk on his face.
Dazai knew that even if Chuuya could at any point use his Ability to help, he wouldn't.
Dazai made quick work of Chuuya's pants. Again, as he pulled them down over Chuuya’s thighs, the bike swayed. Dazai's legs strained with the effort of keeping it balanced.
Still, he undid his own pants and stroked himself in front of Chuuya. Chuuya looked unimpressed, but Dazai would change that. Once he was hard, he slid a condom over himself. He'd brought a small bottle of lube. As he toyed with Chuuya's entrance, Chuuya started to look slightly concerned.
Dazai couldn't understand why. He teased the tip of his cock at Chuuya's entrance, then pushed in.
Chuuya shuddered, and the sound he made spurred Dazai on. He thrust again, and as he did, he leaned forward to grasp Chuuya's shoulders. Chuuya had a strange expression on his face, like he was enjoying it but he also was distracted. One of his hands came up to grab Dazai's shirt.
During a particularly hard thrust, Dazai's foot on one side of the bike left the ground.
His other leg didn't have the strength to keep the balance that had been thrown off by his own movements. Before Dazai could register what was happening, Chuuya had moved, Dazai suddenly had his cock out in the open, and when he tried to lift his leg over the bike to get off, it fell over on top of him.
A sharp pain in his arm broke through the daze of falling over. He lifted his head to see Chuuya sprawled on the ground a few feet away. He tried to lift the bike, only to find it heavier than he thought it would be. He couldn't make it budge, and various bits of it dug into him, pinning him to the ground.
"I told you," Chuuya said, picking himself up and brushing off his clothes. He made sure to pull up his pants and place his hat back on his head before he went over and lifted the bike off Dazai.
He made it look so easy.
Dazai sat up. His left arm throbbed.
"Chuuya, I think my arm is broken."
Chuuya's eyes widened slightly. "Can you move it?"
Dazai tried, and winced. Chuuya knelt down in front of him and rolled up his sleeve, then used his knife to cut away the bandages. The forearm was bruised badly and had already started to swell.
"Oh," he said.
"This is all Chuuya's fault!" Dazai whined.
"Shut up. It was your idea." Chuuya grabbed him by the other arm, pulling him up and towards the street.
"Whoa, whoa!" Dazai dug his heels into the ground. "I'm still exposed!" He pulled his arm out of Chuuya's grip and began doing up his pants. He tossed the condom aside. "Are you taking me to Mori?"
"Fuck no," Chuuya snapped, grabbing his arm again and dragging him down the street. "My ass is a mess. You still have lube on your cock. I bet he knows but I don't want him to know like this. I'm taking you to an actual hospital."
"But--"
"We'll use fake names and be in and out. Would you rather have people we know deal with this and never let us live it down?"
"No..."
"Then shut the fuck up."
Dazai allowed Chuuya to drag him to the hospital. He would still have to explain the injury to Mori, but once he was cleaned up and clear-headed he would be able to come up with a suitable lie.
Chuuya seemed irritated, and Dazai felt annoyed and disappointed.
He hadn't gotten either of them off. One of his arms was out of commission. And he doubted Chuuya would be willing to help alleviate his frustrations after what had happened.
But none of that bothered him as much as Chuuya being able to say, “I told you so.” He knew Chuuya would never let him forget this.
