Dazai leaned back, trying to put some distance between him and the man who just pulled his blanket off for no reason. He was supposed to go to bed, no? "Mori, what are you-"
"Shh," cooed Mori, coming even closer, on all fours on the bed. "Don't call me Mori, okay? Call me something else..." said he, as he pushed Dazai down and started feeling Dazai's sides under his clothes. "I should have put a nightgown on you..."
Dazai was frozen in place. Why was Mori touching him like that out of the blue? Maybe he should've seen this coming.
"Come on, Osamu. Why so silent suddenly? I hope you won't be like that the whole night."
"...I don't like how you're-" A squeeze of his hip pulling him further under Mori made him go quiet again. His expression didn't really show his panic though, and hopefully he'd keep it that way.
"Hm? What? Come on, now... I told you to call me something else, but you haven't called me anything."
It didn't take long before Mori was pulling Dazai's pants off, and that's what finally made him fight back. Almost instinctively, he attempted a light kick, his hands shooting up to try to shove the man away.
"Don't do that!"
Mori went still for a moment, but recovered soon enough and pinned Dazai's wrists to the bed.
"I've been nothing but nice to you so far, so you'd better behave yourself," said he, using his own legs to keep Dazai's still. He then freed one of his hands, using it to pull the stubborn boy's pants off. He left his panties on, which he had carefully selected for him, even while knowing he preferred boxers. Dazai had reluctantly agreed to wearing them, in the condition that his visible clothes are men's clothes.
"These fit you like a glove, don't they?"
"No... they don't..." Dazai's voice was growing quieter, less defiant, as he started to realize that he couldn't do anything. The man on top of him was clearly much stronger than he was, and there was just no way he would let him go. He couldn't move his wrists an inch.
Mori used his knees to push apart Dazai's legs, and lowered his head to the boy's neck for a kiss. With what little defiance he had in him, Dazai lowered his head so as to not give him access to his neck.
"I was trying to be nice, you know. But if you won't cooperate, I suppose I'll just get straight to the point," said Mori, before lowering his free hand and, through the thin fabric of the panties, started rubbing at the boy's clit.
"Ah-" Dazai let out a small whimper, shocked at the sudden touch in that place. He turned his head away and buried it into the plush pillow underneath him, making sure he couldn't make another sound.
"Oh? How cute. I suppose I'll have to free up my hands a bit." Pulling his hand away from there, Mori quickly unbuckled his belt, the lack of one hand making it a little difficult as he folded and maneuvered it into makeshift handcuffs. Of course meeting some resistance from Dazai, which was rendered useless, he used it to cuff his wrists and tie them to the headboard.
Now, with a free hand, Mori grabbed Dazai's hair, and turned his head forward, not letting him muffle himself into a pillow.
Dazai's breath hitched at the slight pain, but he didn't say anything, especially now that he had absolutely no idea on how to get out of there.
Mori's right hand went back to rubbing circles on the boy's clit, a bit harder now than before.
"Mnh- ah!" Dazai's legs twitched, attempting to close, but unable to do so around Mori's own legs. His heart was palpitating, and he kind of hoped it would give him a heart attack and kill him.
Soon enough, Mori switched from outside to shoving his hand inside the panties, feeling around at the clit and the entrance just below. "Why don't you call me Ougai?"
"We're- we're not... close like that.." Dazai protested, trying to keep his voice normal.
"Really? I think we're rather close at the moment, Osamu," said Mori, before shoving a finger inside Dazai, using the boy's own wetness as lubrication.
"Ah!" He cried out, his muscles tightening around Mori's finger, attempting to push him out. "D- don't- ah, call me- ah!" And he let out another sound as the long finger inside him pressed right into his g-spot. "Mori, I don't like that.. please..."
"Please, what? You're still calling me that. Do you think I should put another one in?"
He didn't really wait for an answer, he instead took the liberty himself of choosing to do so, and shoved another finger inside. Now, an adult man with hands such as his, obviously had fingers much bigger than Dazai's thin and delicate ones, and so, the difference in feeling when they were inside was rather great, it was much more filling.
Dazai's eyes rolled up for a moment at the feeling, legs twitching again. "Hah.. please, stop..." He wasn't a fan of begging anything of anyone, but he needed this to be over. Of course, it's not like it'd work anyway.
"Now why would I do that? You look so pretty like this," said he, while pumping his fingers in and out of the boy.
"Ngh- don't- don't call me... pretty..."
"Why? Would you prefer 'handsome'? See, I don't think you look very handsome at the moment. Right now, I think you look pretty. Beautiful, even."
It took until now for Dazai's barrier to finally crumble. It was all so overwhelming, all from the touch to the inability to escape, and now to the fact that Mori wasn't only disrespecting his lack of consent, but he was just disrespecting everything that held him on to humanity. His identity, his preferences, everything. Everything. A tear adorned his eye, which he tried to keep from falling, but failed.
"Come on now, you're so cute like this, why don't you say something?"
Mori was met with more silence. And so, getting a bit bored, he decided to move onto the next step. He took out a condom from his pocket, and after undoing his own pants and freeing his cock, he rolled it on. Luckily it was pre-lubed, so he didn't have to worry about that.
He leaned over Dazai again, and grabbed the back of his hair, forcing him to look at him in the eye. "Look at me, Osamu. Take a deep breath."
Somehow, despite his discomfort, Dazai looked up, his calmness perhaps thanks to some level of dissociation. He took a deep breath, idle.
"Good... now, feel me." And so, pulling the boy's panties to the side, he lined himself up. And slowly, but without stopping, he pushed himself inside to the hilt.
Dazai didn't let out a sound, but his mouth opened in what was almost a gasp. His hands clenched, and his legs felt tense, awkward, and shaky. It's like he could feel Mori not only in his canal, but all over him, and it was disconcerting. His chest moved up and down noticeably as he panted slightly.
"Good, you're... perfect..." Mori breathed out, feeling the tight muscles, warm around him. "Oh, yes, you are."
Soon enough, he started slowly moving, testing the waters. Dazai's eyes were wide, lips parted.
Once it was comfortable enough, Mori grabbed the back of Dazai's thigh with his free hand, still looking him in the eye, and lifted it before pushing in with a harsher thrust.
"A-ah!"
"You keep sounding so pretty, I'll never be able to stop," said Mori before thrusting again. And again, and again.
"Ah, ahn- hah!" Dazai's eyes were wet again from tears, and every time he tried to look away, Mori's grip on his hair kept him looking up.
"Now, my sweet, why don't you be a dear for daddy and call out his name?"
The title he used for himself nearly made Dazai's stomach turn, and the last thing the boy wanted was to do what Mori told him to. Still, reluctantly, he agreed. "Ah.. Ougai..."
"No, sweetheart. Not that one."
That just made it all worse. But each of Dazai's agreements to do something, were just in hopes that it would all end sooner. And so, he did as he was told. "... Daddy..." He said, feeling the uncomfortable heat of shame fill his head and the back of his neck, along with a major discomfort that's been there for a while now.
"Yes, sweetheart. Daddy's here," grunted Mori, as he continued thrusting, now with more force than before.
"Ah, hahh..." Dazai's walls still clenched with every thrust, making it that much more uncomfortable as Mori fucked him nonstop. "Nngh.."
"That's it, Osamu. Feel how daddy's inside you. It feels good. Good..." Mori let out a small, low moan of his own, as he started to get closer. And so, letting go of Dazai's hair, he moved his hand down and started rubbing his clit again.
"Ah! Ah, hah-!" Dazai's legs shook even more, as his most sensitive spot was touched all while he was being penetrated over and over again, making him feel a reluctant pleasure inside. "Hahh... ah..."
"Now, tell daddy how you feel. Are you close?"
"Ngh... ah.. y- yes..."
"Yes, what?"
"Yes, daddy...!"
Upon hearing the boy cry out that word, Mori couldn't help himself. He trusted even faster, erratic now, all whilst rubbing tight circles on his clit, all until both of them finished at once at the same time, leaving Mori feeling ecstatic, and Dazai absolutely disgusted.
