Yandere Rengoku X Tanjirou

Marriage and yandere au

No one pov

It was 12 o'clock when tanjirou arrive Infront of their apartment building,each step he took is getting heavier by the second,his hand shaking a little as he reach fro the door knob and twist it open after unlocking it. Slowly he peak inside to see pitch black and let out a sigh of relief,thinking that his husband is already asleep. Oh how wrong he was.

"Now where did you go until pass midnight tanjirou dear?"

A deep familiar voice ask,he know who the voice belong to. Tanjirou inhale before he let out a nervous smile and look to the side to see his husband sitting in one of the couch,arms crossing against the sturdy chest.

"Uhm..I-I was out w-with a f-friend..."

Tanjirou stutter it out and whimper a bit,afraid that his husband is mad at him. With a sigh the blond stood up and made his way to his wife/husband and pull the smaller male in a hug. His chin resting on tanjirou shoulder and one of his hand is rubbing circle on tanjirou back while the other free hand wrapping tightly around tanjirou petite waist.

"Now now I'm not mad but next time...do tell me ok?"

Rengoku softly whisper and pull away from the hug. His hand under the red head male chin and brought it up to meet his eyes. The blond gaze fall on his partner pink plump lips and without him notice he already lean in. Capturing the other lips on his. Tanjirou wrap his arms around the taller male,eyes close savoring the kiss. Tongue dancing against eachother, exchanging saliva along the way. The suppose to be sweet kiss turn to a make out session in a second. The blond wonder down and pat tanjirou bum twice. Tanjirou understanding by what the blond want jump and wrap his leg around rengoku waist,lips still attached to the blond, tongue still dancing with a trail of drool on the corner of his lips. The blond catch his partner by putting his hand on tanjirou bum and walk away toward their bedroom.

That night fill with loud moans and grunts.

------------------------------------------------------------------------

Rengoku trace his finger on the bitemark he make on tanjirou neck,rengoku is a possessive man. He don't like to share especially his sweet little wife/husband.

"My sweet naive little tanjirou..."

He whisper,hand on the smaller neck,gliding it up and down making tanjirou shiver in his sleep.

"You were out with that woman didn't you?"

The blond question,his hand slip under the blanket to his partner nipple. Twisting it using his finger.

"So innocent..."

He mutter as he glide his hand back up to the smaller male neck.

"Not noticing how that woman look at you"

His thumb caressing Tanjirou slightly chubby cheeks,pinching it and chuckle when the smaller male whine and swat his hand away.

"But don't worry..."

He whisper as he brought the male closer to him, hand wrapping tightly on tanjirou waist. A sickening smile on the blond face.

"I'll protect you..my sweet little tanjirou"

Kanao walk on an alley with her phone in hand. To lost sliding her finger up and down on the phone screen that she didn't notice a tall figure following her. A knife in hand. A wide smile on it face.

Kanao stop on her track when a loud noise suddenly emerge. She look to her side to some mouse running away with it other kind. She let a breath while her hand on her chest,sliding down. But that doesn't last long. The sound of footstep could be heard next. The woman turn to look and widen her eyes when a tall figure,wearing a black hooding smiling at her with wide eyes. Arm up the air with knife in hand,ready to strike.

"This is what you get when you touch what's mine"

Is the last thing kanao heard before darkness engulfed her vision.
