Atsushi had fulfilled Dazai's predictions a little too perfectly. As soon as he closed the bathroom door, he was leaning against the other side, sliding down the door slowly. It took him a few moments for him to calm himself, and during that time, he found himself breathing in Dazai's scent. He didn't know what was going on with him today, and he was honestly shocked by his impulses.
He had never felt anything like this before, even around his crushes at the orphanage. That was obviously all this was going to be for him; a crush on a kind, sexy older man that wouldn't run any… deeper… right? Or maybe it was just teenage hormones changing from self hatred into specific impulses. This was completely natural. One hundred percent normal. He just needed to take care of himself a little, especially the hardening bulge in his pants, and then he wouldn't be nearly as flustered as before.
With that reasoning in mind, he began to slowly strip. His clothes were basically shreds by this point, and between the storm and an extended period of homelessness, they were almost grafted onto his body. He looked over at the clean clothes with a small smile. It had been ages since he had something clean to wear, and even longer since he had a shower. He tossed his old rags into the trash before turning the shower handle and stepping in. He didn't know much about Dazai, but he knew so long as that man was around, he wouldn't have to worry about clothes again. Part of him was still worried though as he scrubbed various soaps in his hair and across his body, that if stayed around Dazai, that what he was about to do would become a terrible habit.
Atsushi dragged his sud-covered hands slowly down his thin, pale body, washing everywhere but the one place that wanted it the most. He had always been reluctant to touch that specific area, especially at times like this where it demanded his attention, and yet, it had to be done. He knew full well a cold shower wouldn't help him this time. Normally, he chose not to use his imagination when he did this; he would just stare at a blank wall or close his eyes and enjoy the darkness, but this wasn't a normal action for him to begin with. He closed his eyes as his fingers wrapped around his length and let out a sharp gasp; he was much more sensitive this time than any of the others.
Biting his lip, he began to stroke his erection slowly. He knew this apartment had thin walls, he could hear Dazai's double suicide song earlier from the kitchen. He knew he had to be quiet or Dazai would hear him touching himself, but he kind of wanted Dazai to hear at the same time. He had no way of knowing, for the time being, if Dazai was gay; and he doubted Dazai wanted him already if he was, but he knew he still wanted the man.
He imagined Dazai pressed against his back in the shower, the brunette's hand wrapped around his own, guiding him as he stroked his member, picking up speed. Atsushi moaned quietly, he was already so close from the image alone. He could almost hear Dazai whispering in his ear, telling him how to do it. "Lighten up your grip a little bit, yes just like that. Good boy~" He moaned louder and almost came from just that one imaginary praise. He was sure Dazai heard him that time, but maybe he would think it's just because of the hot water. Yeah, that's what it would be.
Atsushi saw a flash of lightning close by in his peripheral, but he didn't care by this point; he was too deep into his imagination and trying his best to hide any further sounds. His legs began to tremble, he held onto the wall for balance. His vision went white as his unevenly cut hair and his breathing became erratic. Atsushi screamed with pleasure as thunder shook the building, knocking out the power. He was worried, but it was too late; the orgasm knocked him to his knees where he stayed quivering as soap bottles rained down on him, letting the water wash away his mess in his half-panicked, half-overstimulated state of mind.
"Atsushi-kun! Are you okay?" Dazai burst into the bathroom when he didn't answer to find the dim silhouette of the boy on the shower floor, undoubtedly bruised from the plastic bottles.
"I-I'm fine, Dazai-san," he replied, turning off the shower. "W-would you mind handing me a towel? A-and not looking please?" Atsushi squeaked from embarrassment, hiding his body from those pretty brown eyes. Dazai gave him a big soft towel, but knowing full well the boy couldn't see him, he took this opportunity to look him over; he had been good enough for today given that he had stayed outside of the bathroom when Atsushi was moaning his name in the shower. Dazai has always seen very well in the dark, and when lightning was still flashing for a split second at a time, he could see even better; every part of the boy from the suds still clinging to his ankle to his soft, creamy thighs to the pink head of his cock, continuing to the blush that still painted everything from his chest to his adorable expression. He was biting his bottom lip, staring wide-eyed at Dazai as his right arm covered his perky nipples and his left was locked in a straight line between his legs. He couldn't wait to see this in more light, but that would have to wait until at least tomorrow; he wanted the boy to trust him after all.
Dazai licked his lips, "Do you need help up?" He asked, crouching down to Atsushi's level with his eyes closed-as far as Atsushi could see, that is. Atsushi nodded, taking Dazai's hand. Dazai lifted them both until they were standing, "I'll get some flashlights," Dazai's smile carried in his voice, "Be careful getting dressed," and with that, Dazai left Atsushi to dress himself. Atsushi let out a sigh of relief as he slipped into the clothes Dazai gave him earlier.
