It's only casual for the both of you to be intimate with each other without any plans to be in a commited relationship. It was almost evening when you just woke up on his bed, again. You glanced all over the room and your eyes met his figure on the bedside, smoking. You slowly sat up and asked him if you could have some cigarette.

He narrows his eyes at you in response.

"you've never asked me for a cigarette before."

Sukuna takes in another drag, exhaling the smoke out through his nose.

"Don't tell me you're starting to get addicted to me or something."

There's a hint of amusement in his tone as he says this. His eyes still on you, still trailing along your body, taking in every curve, every mark littered on your skin.

"Addicted? In your dreams." You said.

He snorts at your response, finding your denial amusing.

"Hmph, says the one currently in my bed, smoking my cigarettes."

Sukuna smirks, taking another drag of his cig, eyes still roaming over your body. His gaze is both intense and amused, as if he was finding this whole situation quite entertaining.
