Work Text:
Months have passed since Sigma joined the agency; a recommendation from Dazai himself. The man seemed ecstatic to have someone new to torment.
“A new victim,” as Kunikida put it. Though, the way Dazai would tease Sigma seemed… Different. Oftentimes, along with verbal teasing, Dazai would hug (and occasionally kiss) Sigma.
Neither of them thought much of it; it was just Dazai being Dazai.
The two had shared a living space.
For the first few weeks, Dazai had slept in the living room. Eventually, he wriggled his way into bed with Sigma.
At first, the two slept at least a foot apart. Day by day Dazai would scoot closer, and eventually, their backs would be flush against each other.
Before long neither of them could sleep without holding the other.
It had started with Dazai’s usual teasing.
“You’re no fun, Sigma.” His tone was whiny, drawing out Sigma’s name. His arms wrapped around Sigma’s waist, his chest flush with his back.
“Let go of me.” Despite Sigma’s dissatisfied tone, he leaned back into Dazai’s embrace. He had long since gotten used to the physical nature of Dazai’s teasing; he even began to enjoy it. A shiver went down his spine when he felt Dazai’s lips on the back of his neck.
“No thanks. Seeing you upset makes me happy.”
Sigma scoffed, “You’re insufferable.” He pushed Dazai off, turning around to face him. His brow twitched as Dazai wrapped his arms around him once more.
“But you love it.”
Sigma couldn't deny it; he did. Dazai made him feel human. He gave him a reason to live.
Dazai knew he wouldn't get a reply, simply smiling and capturing Sigma’s lips in a kiss.
Dazai’s tongue ghosted over Sigma’s lips. The ladder pushed away, staring at Dazai like he had seen a ghost.
That was a new one.
“What are you doing?” Sigma’s tone was a blend of surprise and displeasure.
Dazai simply smiled and pulled Sigma closer, “Just trust me, okay?”
Reluctantly Sigma allowed Dazai to kiss him again. This time he parted his lips, letting Dazai’s tongue slip into his mouth. Sigma’s brows furrowed, unsure of what to do.
There was a burning feeling in his gut, something he'd never felt before. It was like a flame that threatened to envelop him whole. He could feel his face heating up, his breathing becoming uneven. He grasped the front of Dazai’s vest with shaky hands.
Dazai pulled away with a large grin, “Wow! This view is even greater than I imagined,” he leaned in to kiss Sigma once more.
Sigma clicked his tongue, using his hand to block Dazai’s lips, “Don’t.”
Dazai licked his hand in response. Sigma was quick to shove him away, making a sound of disgust.
Something was off. Very off.
Sigma’s knees were weak and he felt himself tremble slightly. He felt like he was drowning; like that feeling in his gut rushed to his head and clouded his senses.
While at home Sigma only wore his turtleneck, forgoing the countless outer layers of his usual outfit. This made it easy for Dazai to slip his hands underneath, feeling his soft skin, and exploring every inch of Sigma’s upper body.
Each touch, every caress, leaving behind a feeling of pins and needles. The feeling of such a gentle, caring touch was completely foreign to Sigma.
“Such pretty skin,” Dazai cooed, “and such a beautiful figure.” His hands traced over the curves of Sigma’s hips.
Sigma laid bare on the futon, his legs tightly drawn together in an almost pathetic attempt to hide himself. Dazai, half-dressed, rummaged around the bottom of the closet, retrieving a small bottle.
Sigma’s face flushed when he caught sight of it, “Why do you just… Have that?” He frowned slightly.
“For a moment such as this.” Dazai smiled with mirth.
Of course, he predicted this. Sigma couldn't help but roll his eyes. He inhaled a sharp breath when he felt Dazai’s hands on his thighs.
“Just relax for me, ‘kay?” Dazai cooed in a playful tone. One of his lube-coated fingers circled Sigma’s rim, earning a small whimper. When that finger slipped inside, it felt almost impossible to relax. The feeling was unpleasant, accompanied by a dull pain. Sigma’s brow furrowed tightly.
Dazai’s eyes were filled with genuine concern as he leaned forward to kiss Sigma’s cheek softly. Such soft actions were a rarity coming from Dazai. Sigma hissed in pain as he began to move his finger.
Sigma willed his muscles to relax. The pain subsided and the resulting feeling was rather… pleasant. His grip on the duvet tightened.
“I’m adding another. Is that alright?” Dazai used his free hand to gently caress Sigma’s cheek. Sigma nodded in return.
The pain returned when a second finger was added. All of Sigma’s muscles tensed against his will.
Yet all of the displeasure seemed to disappear when Dazai’s lips met his. A small whimper escaped him as he relaxed once more.
Dazai curled his fingers-
“Ah!” A sharp sound of pleasure and surprise ripped out of Sigma. His back arched off the futon. The feeling seemed to ripple throughout his entire body, causing him to tremble.
Dazai looked extremely pleased with himself, curling his fingers again. Each time Dazai’s fingers brushed against Sigma’s prostate, the louder his moans became. He began to move his hips unconsciously, fucking himself on Dazai’s fingers.
“You’re quite needy for your first time,” Dazai removed his fingers. The resulting squelch grounded Sigma, making his face flush.
“Just shut up.” Sigma frowned as Dazai wiped his fingers on his inner thigh. He eyed Dazai as he removed his trousers, finally freeing his hard-on. Sigma pursed his lips and looked away.
“Why are you looking away now? Am I not pleasant to look at?” Dazai pried Sigma’s legs open, leaving them to rest on either side of his hips.
“Not particularly.” Sigma huffed, he could only pretend to be annoyed. This facade wouldn't last long, though.
Without warning Dazai plunged into him. Sigma cried out in pain, gripping the duvet under him like a lifeline. Dazai went completely still.
“Are you alright? Do you want to stop?” Dazai’s voice was soft, as was his gaze. His concern was genuine as he gazed at the man lying underneath him.
Sigma nodded slightly, “it's fine, keep going.” His legs wrapped around Dazai’s hips tightly, pulling him closer, their bodies flush with one another.
Dazai smiled softly, leaning forward to capture Sigma’s lips with his own. Both hands gripped Sigma’s waist tightly.
He began to thrust his hips at a slow pace. Sigma wrapped his arms around Dazai’s neck, kissing him between moans. Dazai’s pace quickened as Sigma’s body adapted to taking in his length.
Sigma’s moans became more desperate and his nails dug into Dazai’s back. He felt himself losing himself to pleasure. His back arched, all of his muscles clenched, and he cried out.
“Dazai!” The moan that followed was guttural as his eyes rolled back. His entire body quivered as he reached his climax, cum spilling onto his abdomen and pooling at his navel.
Hearing his name uttered in such a way sent Dazai over the edge. With one last, rough thrust of his hips, he groaned in ecstasy. All was still for a moment.
Cum leaked out of Sigma when Dazai pulled out, dripping onto the duvet. Neither of them could bother with the resulting mess currently.
Dazai collapsed next to Sigma and pulled him close. The two embraced tightly, as lovers would. Though neither of them felt human enough to experience “love.”
“I think,” Sigma paused, pondering what his next words should be, “I think you make me feel.” He felt somewhat stupid saying it out loud, but there were no words to describe what he was feeling in his soul.
“Yeah?” Dazai laughed, “I think you make me feel, too.”
