Dazai smirks at his girlfriend from across the room.
(Y/n) winks at the brunette and continues her conversation with the president.
The said elder didn't pay attention to the young couple as he continued to talk about her next mission.
As the minutes tick by, the more devious the detective's plan for the night to come.
"Dazai, I presume you and Kunikida will be ready for next week?" The president questions, turning to the suicidal maniac.
"Of course, president. (Y/n) and I have plans tonight though, may we be excused?"
The older man smiles at the young woman and rubs her shoulder. "Have a nice night. Congratulations on your five year anniversary."
"Thank you Yuki." The woman responds and kisses the man's cheek. "See you tomorrow."
Dazai takes (Y/n) home and as soon as they are inside he kisses her neck.
The woman moans softly and tugs on his hair. "Dazai~" she whispers.
A growl exits his lips as he slams her hands above her head.
"I told you little mystery, I hate pain. Although my little mystery, I have no problem dishing it out."
Her arms wrap around his neck as he carries her to their bedroom.
"Five years and this is how our first time is gonna go?" She pouts and pokes his nose.
The brunette smirks. "Would you have it any other way?"
"No," she whispers.
"Good." He whispers back and throws her on the bed.
The couple throws their clothes to the ground and Dazai crawls up and hovers over her.
"You won't do anything too crazy right?"
"You know the safeword right?"
"Grapefruit." She responds and rips off his bandages.
The brunette laughs and nods. "I still think it would be funny if it was Kunikida."
(Y/n) rolls her eyes and grips his hair.
A groan slips out and he growls.
"Stop messing around."
"And I said-" Dazai throws her hands above her head. "No pain," he finishes. He bites and sucks on her neck to leave a dark mark just below her jaw.
The white bandages hold her hands together tightly.
(Y/n) whines cutely.
"Do that again and I'll tie one around your eyes."
The woman resigns to a pout but makes no noise.
Dazai smirks and nods. "Such a good little slut."
She rolls her hips but he holds her down.
He rubs the tip along her entrance, getting it wet with her juices.
"Osa~ please hurry." (Y/n) begs and tugs on her restraints.
Suddenly he thrusts balls deep inside her, causing her to moan loudly.
Her back arches off the bed and she grips the headboard tightly.
He pulls out all the way and slams back in again.
A whimper comes from the woman but she grips his face and smashes their lips together.
Dazai obliged and kissed back passionately.
His thrusts are slow but sharp.
Just as she was about to release he stops.
"Osa!" She exclaims looking into his eyes.
The brunette smirks and pulls away, getting off the bed.
"Y-you can't leave me like this. I was about to-"
"Oh I know, little mystery. I'll be right back I promise."
She cries out softly and thrusts up. She didn't want to wait so she went to touch herself.
Dazai slaps her hands away and ties them to the headboard. "I didn't say you could please yourself. That's my job."
"Then finish the job." She orders angrily.
The detective smirks and leaves the room.
(Y/n) whines loudly as she tugs on the bandages.
Soon enough Dazai comes back with a glass of water.
"You jerk! I'm soaking and you edge me and now you're ignoring me? I hate you!" She yells.
Dazai hovers over her once more and his hand squeezes her throat. "Run that by me again." He growls.
"I. Hate. You." She punctuates every word.
The man growls and bites her neck.
This time it bleeds but (Y/n) moans softly.
He licks up her blood and squeezes both her neck and hip.
"If you want it so bad then beg me. Like the slutty whore I know you are."
"Fuck me daddy~ I'm throbbing and dripping for only you. I need you inside me. Hard and rough. Use me but please~ please let me cum."
"Where's the fun in that?" Dazai questions and slams into his girlfriend, thrusting fast and hard.
(Y/n) moans loudly and bucks her hips wildly.
Dazai pulls out, flipping her onto her knees.
Her head hangs between her arms and her ass is up.
He slaps her ass hard, causing her to whimper and moan.
After each thrust he spanks her, getting harder each time.
After a while her ass is raw and tears are streaming down her cheeks.
"I-I need to cum. Please let me." She begs weakly.
Dazai presses his chest against her back and nibbles on her ear.
She pants heavily and grips the headboard.
"Cum." He orders and immediately she releases, moaning loudly.
He follows shortly after, after thrusting a few more times.
A low groan exits his lips.
"You're such a whore for me aren't you my little mystery?"
"Yes daddy," she whispers.
Dazai unties her hands and puts the bandages on the bedside table.
She gently rubs her fingers over her wrists and he notices.
"Why didn't you say anything?" He whispers and kisses each wrist gently.
"Because I am the masochist to your sadist."
Dazai frowns and holds her in his lap. "Yeah but I want you to feel pleasure too, not just pain."
"I did. I was a mess for you. Did you not see or hear me?" (Y/n) laughs softly.
Dazai sighs but nods. "As long as you're ok."
"I'm more than ok. Oh and I'm really sorry I said I hate you. I promise I don't. I just-"
"I understand. I can only imagine being edged like that."
(Y/n) smirks and lays down.
"That was not an invitation." The brunette counters.
"But the release is pure ecstasy when you're edged a few times." The woman offers.
"No. Happy 5 years though my little mystery."
(Y/n) kisses her boyfriend as he pulls her close.
